Southern Cross Gold Drills 0.6 m @ 972 g/t Gold in Apollo and Drills Easternmost Mineralization

September 02, 2026 6:00 AM EDT | Source: Southern Cross Gold Consolidated Ltd.

Vancouver, British Columbia and Melbourne, Australia--(Newsfile Corp. - September 2, 2026) - Southern Cross Gold Consolidated Ltd (TSX: SXGC) (ASX: SX2) (OTCQX: SXGCF) (FSE: MV3) ("SXGC", "SX2" or the "Company") announces results from five drill holes at the 100%-owned Sunday Creek Gold-Antimony Project in Victoria, showing the increase in grade at depth in Apollo and extended Sunday Creek to its furthest eastern point to date with high grades in up-dip areas of Apollo East (Figures 2 to 6).

SDDSC222W1 returned the headline result, 0.6 m @ 993.2 g/t AuEq (972.0 g/t Au, 8.9% Sb) from 808.5 m, the 9th best composite intersection drilled at Sunday Creek, 620 m below surface. SDDSC227 returned the shallowest high-grade intersection drilled in Apollo East, 5.1 m @ 27.2 g/t AuEq including 2.6 m @ 51.1 g/t AuEq from 260.9 m and only 144 m below surface, and the most easterly and shallowest drill intersection on the project, along with an antimony assay of 32.5% Sb. Five individual assays in this release exceed 50 g/t Au, ranging from 97.6 g/t to 972.0 g/t.

Four High Level Takeaways: 

  1. Grades continue to strengthen at depth in Apollo. SDDSC222W1 returned 0.6 m @ 993.2 g/t AuEq (972.0 g/t Au, 8.9% Sb) from 808.5 m, extending the A130 vein set 40 m below its known vertical depth extent. The intersection ranks as the 9th best intersection drilled at Sunday Creek to date, returned approximately 620 m below surface. 

  2. High-grade mineralization now extends much closer to surface in Apollo East. SDDSC223 and SDDSC227 both extended the Apollo East vein sets up-dip, with SDDSC223 returning 97.6 g/t Au, 144 m below surface, and SDDSC227 delivering 5.1 m @ 27.2 g/t AuEq (18.4 g/t Au, 3.7% Sb) from 260.9 m, including individual assays of 186.0 g/t Au and 116.0 g/t Au. Both high-grade assays sit inside a 2.6 m @ 51.1 g/t AuEq interval. 

  3. The Apollo East corridor keeps expanding along strike to the east. SDDSC222 alone intersected seven separate Apollo East vein sets across prospective terrain and combined with the up-dip results from SDDSC223 and SDDSC227, Apollo East is now defined across 140 m of horizontal strike, reinforcing that this is a broad, multi-vein system. Apollo East is one of five mineralized areas along 1,550 m of drill-defined host strike, of which approximately 650 m has been intensively drill tested. SDDSC227 also returned the easternmost significant intersection drilled at the main Sunday Creek Project to date, approximately 110 m below surface and directly beneath mineralization identified in the MTSC001 trench completed in 2021, which it likely extends down-dip. 

  4. Antimony grades strengthen alongside the gold in shallow Apollo East. SDDSC227 returned 32.5% Sb, one of five individual assays above 15% Sb reported for Apollo East. Together, they show Apollo East carries high-grade gold and meaningful antimony grades into shallow areas. The 186.0 g/t Au assay carried 5.2% Sb, and SDDSC222 returned three individual assays above 15% Sb at depth, showing antimony tenor is carried through the full vertical extent of the system. 

Michael Hudson, President & CEO, states: "This release does two things at once. SDDSC222 and its wedge SDDSC222W1 pushed Apollo down-dip, returning 972 g/t gold over 0.6 m at 620 metres vertical depth, our 9th best intersection at Sunday Creek. SDDSC223 and SDDSC227 extended Apollo East to its shallowest and easternmost extensions. Grades keep improving with depth at Sunday Creek rather than tailing off, but they are not absent at surface either.

"SDDSC227 makes the point better than any hole here: 32.5% antimony, alongside individual gold assays of 186.0 g/t and 116.0 g/t, all within 144 m of surface. SDDSC227 returned 5.1 m @ 27.2 g/t gold equivalent including 2.6 m @ 51.1 g/t and also delivered the easternmost significant intersection drilled at Sunday Creek to date, 110 m below mineralization we trenched at MTSC001 back in 2021. Apollo East is open to the east and we intend to keep pushing it in that direction.

"We are growing Apollo and Apollo East in both directions at once, and with eleven rigs turning, results pending from 72 holes and our 200,000 m program running through to Q1 2027, we expect to keep delivering."

SDDSC222W1 returned the 9th best composite result on the project to date which is located approximately 620 m below surface, extending the A130 vein set 40 m deeper. SDDSC222W1 intersected a further 125 m of down-hole prospective terrain, including a broad 20 m zone of lower-grade mineralization from 873.2 m confirming down-dip structural continuation of multiple Apollo vein sets. Highlights included: 

  • 0.6 m @ 993.2 g/t AuEq (972.0 g/t Au, 8.9% Sb) from 808.5 m

For Those Who Like the Details - Highlights: 

SDDSC223 returned 97.6 g/t Au with 1.7% Sb over 0.10 m from 280.5 m, about 144 m below surface, in a narrow, previously undefined gold-rich vein set hosted in altered sediments. SDDSC223 remained within prospective terrain for 163 m down-hole and tested the southern-most strike continuation of multiple Apollo East vein sets. Highlights include:

SDDSC227 intersected seven vein sets in the upper Apollo East, with the best results from two narrow, closely spaced high-grade zones: 116.0 g/t Au with 32.5% Sb over 0.5 m from 260.9 m and 186.0 g/t Au and 5.2% Sb over 0.2 m from 263.4 m. Both sit within a broader mineralized zone and are among the shallowest high-grade intersections drilled within Apollo East to date: The upper zone sits 144 m below surface and is the shallowest high-grade intersection drilled in Apollo East to date, while a further intersection in the hole is the easternmost significant intersection drilled at the main Sunday Creek Project, approximately 110 m below surface mineralization identified in the MTSC001 trench.

Drill Hole Discussion

This release reports results from five drill holes at the Sunday Creek Gold-Antimony Project, extending both the Apollo and Apollo East areas of the project. All holes were drilled in an east to west orientation.

Holes reported show the increase in grade at depth in Apollo and extend Sunday Creek to its furthest eastern point to date with high grades in up-dip areas of Apollo East (Figures 2 to 6).

SDDSC222

SDDSC222 was drilled to test the up-dip extension of previously unrecognised Apollo East vein sets and to provide south-bounding information for Apollo vein sets at depth.

The hole intersected a broad zone of stacked subvertical mineralization between 533.4 m and 651.4 m, with higher-grade zones towards the base of the interval. Cumulatively SDDSC222 tested 135 m of down-hole prospective terrain within Apollo East, intersecting seven Apollo East vein sets. SDDSC222 provided 40 m to 70 m up-dip extensions of several Apollo East vein sets from previously defined drilling including SDDSC170A (refer to ASX announcement dated 8 September 2025) and SDDSC181 (refer to ASX announcement dated 17 December 2025).

Drilling intersected the Admiral Fault from approximately 732 m. Rather than close the hole out at its originally planned 770 m depth, the strength of results above the fault supported extending and wedging SDDSC222 at 747.7 m to continue as SDDSC222W1, allowing a single hole to also capture targets originally planned for a separate future drill hole, an estimated saving of around 750 m of future drilling.

Selected composite highlights from SDDSC222 included:

  • 1.0 m @ 17.7 g/t AuEq (0.4 g/t Au, 7.2% Sb) from 575.4 m, including:

    • 0.4 m @ 43.1 g/t AuEq (0.8 g/t Au, 17.7% Sb) from 575.4 m

  • 5.7 m @ 7.5 g/t AuEq (4.3 g/t Au, 1.3% Sb) from 597.3 m, including:

    • 3.4 m @ 10.8 g/t AuEq (6.1 g/t Au, 1.9% Sb) from 598.4 m

  • 1.0 m @ 7.8 g/t AuEq (5.6 g/t Au, 0.9% Sb) from 605.2 m

  • 0.9 m @ 17.5 g/t AuEq (3.8 g/t Au, 5.7% Sb) from 619.1 m

  • 2.1 m @ 20.0 g/t AuEq (20.0 g/t Au, 0.0% Sb) from 635.8 m, including

    • 0.4 m @ 108.0 g/t AuEq (108.0 g/t Au, 0.0% Sb) from 635.8 m

  • 2.1 m @ 6.8 g/t AuEq (4.4 g/t Au, 1.0% Sb) from 640.8 m, including:

    • 1.6 m @ 8.2 g/t AuEq (5.6 g/t Au, 1.1% Sb) from 640.8 m

SDDSC222 intersected one individual assay exceeding 50 g/t Au:

  • 108.0 g/t Au & 0.02% Sb over 0.38 m from 635.78 m

Additionally, SDDSC222 returned three (3) individual assays exceeding 15% antimony

  • 17.70% Sb & 0.8 g/t Au over 0.40 m from 575.43 m

  • 18.30% Sb & 20.7 g/t Au over 0.10 m from 619.79 m

  • 26.20% Sb & 5.2 g/t Au over 0.11 m from 619.89 m

SDDSC222W1

SDDSC222W1 continued from the SDDSC222 wedge point before intersecting a 0.6 m mineralized quartz-stibnite shear vein (high grade core) from 808.5 m as the standout result of this hole, returning 0.6 m @ 993.2 g/t AuEq (972.0 g/t Au, 8.9% Sb) and represents the 9th best composite intersection returned at Sunday Creek to date (see Figure 1). This intersection also increases the known vertical depth extent of the Apollo A130 vein set by approximately 40 m. This intercept sits approximately 620 m below surface, consistent with the pattern observed elsewhere at Sunday Creek of grades improving with depth.

In total SDDSC222W1 broadly intersected 125 m of down-hole prospective terrain, including a broad 20 m zone of lower-grade mineralization from 873.2 m to 893.2 m confirming down-dip structural continuation of the multiple vein sets.

Beyond 900 m drilling added useful strike-extent information on multiple Apollo vein sets at depth and will aid in future targeting.

Selected composite highlights include:

SDDSC222W1:

  • 0.6 m @ 993.2 g/t AuEq (972.0 g/t Au, 8.9% Sb) from 808.5 m

SDDSC222W1 intersected one individual assay exceeding 50 g/t Au:

  • 972.0 g/t Au & 8.85% Sb over 0.60 m from 808.52 m

SDDSC223

SDDSC223 tested the up-dip continuation of Apollo East vein sets and the southern-most strike continuation of multiple Apollo East vein-sets. SDDSC223 intersected several mineralized zones of antimony and gold, with the best results within the upper part of the hole, associated with a high-grade (97.6 g/t Au & 1.7% Sb over 0.10 m) sample within a previously undefined gold-rich vein set hosted within altered sediments, approximately 144 m below surface. In total SDDSC223 stayed within prospective terrain for 163 m downhole.

Selected composite highlights include:

  • 1.0 m @ 7.0 g/t AuEq (3.2 g/t Au, 1.6% Sb) from 236.7 m, including:

    • 0.8 m @ 8.9 g/t AuEq (3.8 g/t Au, 2.1% Sb) from 236.7 m

  • 2.3 m @ 13.9 g/t AuEq (11.2 g/t Au, 1.1% Sb) from 245.3 m

  • 0.1 m @ 48.6 g/t AuEq (41.0 g/t Au, 3.2% Sb) from 266.1 m

  • 1.4 m @ 11.4 g/t AuEq (10.9 g/t Au, 0.2% Sb) from 280.1 m, including:

    • 0.1 m @ 101.6 g/t AuEq (97.6 g/t Au, 1.66% Sb) from 280.45 m

SDDSC227

SDDSC227 tested the upper Apollo East vein sets and returned 32.5% Sb, along with individual gold assays of 186.0 g/t Au and 116.0 g/t Au, both tied to a mineralized stibnite vein. Those two closely spaced high-grade zones sit within a broader 5.1 m at 27.2 g/t AuEq. This is the shallowest high-grade intersection drilled within Apollo East to date, 144 m below surface.

Higher in the same hole, SDDSC227 returned the easternmost significant intersection drilled at the main Sunday Creek Project to date, returning 0.8 m @ 10.8 g/t AuEq (7.8 g/t Au, 1.3% Sb) from 209.0 m, approximately 110 m below surface. It sits directly down-dip of gold-antimony mineralization exposed at surface in exploration trenches, 110 m above, and is interpreted as its down-dip extension. These trenches returned (TSX Mawson Gold news release dated 6 October 2021):

  • Trench MTSC001: 14.0 m @ 12.2 g/t AuEq (11.5 g/t Au,0.3% Sb), including:

    • 8.0 m @ 20.6 g/t AuEq (19.6 g/t Au, 0.4% Sb)

  • Trench MTSC002: 2.0 m @ 5.4 g/t AuEq (4.9 g/t Au, 0.2% Sb)

Selected composite highlights include:

  • 0.8 m @ 10.8 g/t AuEq (7.8 g/t Au, 1.3% Sb) from 209.0 m

  • 5.1 m @ 27.2 g/t AuEq (18.4 g/t Au, 3.7% Sb) from 260.9 m, including

    • 2.6 m @ 51.1 g/t AuEq (34.2 g/t Au, 7.1% Sb) from 260.9 m

  • 7.8 m @ 5.8 g/t AuEq (3.7 g/t Au, 0.9% Sb) from 323.8 m, including

    • 1.3 m @ 10.2 g/t AuEq (8.7 g/t Au, 0.6% Sb) from 325.9 m

    • 0.4 m @ 47.6 g/t AuEq (25.1 g/t Au, 9.4% Sb) from 328.6 m

  • 0.3 m @ 44.0 g/t AuEq (44.0 g/t Au, 0.0% Sb) from 334.9 m

SDDSC227 intersected two individual assays exceeding 50 g/t Au:

  • 116.0 g/t Au & 32.50% Sb over 0.48 m from 260.88 m

  • 186.0 g/t Au & 5.19% Sb over 0.16 m from 263.37 m

In addition to the plus 50 g/t Au grades listed above, SDDSC227 returned one (1) additional individual assay exceeding 15% antimony:

  • 18.00% Sb & 37.4 g/t Au over 0.20 m from 328.82 m

SDDSC234

SDDSC234 tested the down-dip continuation of Apollo East vein sets confirmed in the preceding holes. Although SDDSC234 intersected close to 150 m of prospective terrain including dyke and altered sediments, it returned more modest results than the other Apollo East holes in this release, as it skimmed the southern strike extension of multiple Apollo East vein sets. SDDSC234 also provided a 70 m up-dip extension from previously released hole SDDSC124 on the A179 vein set (ASX announcement dated 26 September 2024).

Selected composite highlights include:

  • 0.3 m @ 7.7 g/t AuEq (7.2 g/t Au, 0.2% Sb) from 268.8 m

  • 1.1 m @ 7.0 g/t AuEq (5.4 g/t Au, 0.7% Sb) from 323.4 m, including:

    • 0.6 m @ 11.6 g/t AuEq (9.0 g/t Au, 1.1% Sb) from 323.9 m

Pending Results and Update

Eleven drill rigs are currently operational at Sunday Creek. Results are pending from 72 holes, comprising 50 holes at Sunday Creek and 22 regional holes, all currently being processed and analyzed. These include eleven holes actively being drilled and three abandoned holes (Figure 3). The Company's 200,000 m drill program continues through to Q1 2027.

About Sunday Creek

The Sunday Creek epizonal-style gold project is located 60 km north of Melbourne within 16,900 hectares ("Ha") of granted exploration tenements. SXGC is also the freehold landholder of 2,296 Ha that forms the key portion in and around the main drilled area at the Sunday Creek Project.

Gold and antimony form in a relay of vein sets that cut across a steeply dipping zone of intensely altered rocks (the "host"). These vein sets are like a "Golden Ladder" structure where the main host extends between the side rails deep into the earth, with multiple cross-cutting vein sets that host the gold forming the rungs. At Apollo, Golden Dyke and Rising Sun these individual 'rungs' have been defined over a 600 m depth extent from surface to over 1,200 m below surface, are 2.5 m to 3.5 m wide (median widths), locally up to 10 m, and 20 m to 100 m in strike.

Cumulatively, 283 drill holes for 136,940.59 m have been reported from Sunday Creek since late 2020. This amount includes five holes for 929 m that have been drilled for geotechnical purposes and 23 holes for 3,104.12 m that were abandoned due to deviation or hole conditions. Fourteen drill holes for 2,382.74 m have been reported regionally outside of the main Sunday Creek drill area. A total of 64 historic drill holes for 5,599 m were completed from the late 1960s to 2008. The project now contains a total of ninety-eight (98) composite intersections exceeding 100 g/t Au and eighty-three (83) composite intersections between 50 g/t and 100 g/t Au, and one-hundred and eleven (111) composite intersections exceeding 10% Sb by applying a 1 m (down hole length) @ 5 g/t AuEq lower cut.

Southern Cross Gold's systematic drill program is strategically targeting these significant vein formations, which are currently drill defined over 1,550 m strike of the host dyke/sediment ("rails of the ladder") from Christina to Apollo prospects, of which approximately 650 m has been more intensively drill tested (Golden Dyke to Apollo). At least 125 'rungs' have been defined to date, defined by high-grade intercepts (20 g/t Au to >7,330 g/t Au) along with lower grade edges. Ongoing step-out drilling is aiming to uncover the potential extent of this mineralized system (Figure 4).

Geologically, the project is located within the Melbourne Structural Zone in the Lachlan Fold Belt. The regional host to the Sunday Creek mineralization is an interbedded turbidite sequence of siltstones and minor sandstones metamorphosed to sub-greenschist facies and folded into a set of open north-west trending folds.

Further Information

Further discussion and analysis of the Sunday Creek project is available through the interactive Vrify 3D animations, presentations and videos all available on the SXGC website. These data, along with an interview on these results with President & CEO/Managing Director Michael Hudson can be viewed at www.southerncrossgold.com.

No upper gold grade cut is applied in the averaging and intervals are reported as drill thickness. However, during future Mineral Resource studies, the requirement for assay top cutting will be assessed. The Company notes that due to rounding of assay results to one significant figure, minor variations in calculated composite grades may occur.

Figures 2 to 6 show project location, plan and longitudinal views of drill results reported here and Tables 1 to 3 provide collar and assay data. The true thickness of the mineralized intervals reported individually as estimated true widths ("ETW"), otherwise they are interpreted to be approximately 55% to 80% of the sampled thickness for other reported holes. Lower grades were cut at 1.0 g/t AuEq lower cutoff over a maximum width of 2 m with higher grades cut at 5.0 g/t AuEq lower cutoff over a maximum of 1 m width.

Critical Metal Epizonal Gold-Antimony Deposits

Sunday Creek (Figure 5) is an epizonal gold-antimony deposit formed in the late Devonian (like Fosterville, Costerfield and Redcastle), 60 million years later than mesozonal gold systems formed in Victoria (for example Ballarat and Bendigo). Epizonal deposits are a form of orogenic gold deposit classified according to their depth of formation: epizonal (<6 km), mesozonal (6 km to 12 km) and hypozonal (>12 km).

Epizonal deposits in Victoria often have associated high levels of the critical metal, antimony, and Sunday Creek is no exception. China claims a 56 per cent share of global mined supplies of antimony, according to a 2023 European Union study. Antimony features highly on the critical minerals lists of many countries including Australia, the United States of America, Canada, Japan and the European Union. Australia ranks seventh for antimony production despite all production coming from a single mine at Costerfield in Victoria, located nearby to all SXGC projects. Antimony alloys with lead and tin which results in improved properties for solders, munitions, bearings and batteries. Antimony is a prominent additive for halogen-containing flame retardants. Adequate supplies of antimony are critical to the world's energy transition, and to the high-tech industry, especially the semiconductor and defence sectors where it is a critical additive to primers in munitions.

Antimony represents approximately 15% to 17% in situ recoverable value of Sunday Creek at an AuEq of 2.39 ratio.

About Southern Cross Gold Consolidated Limited (TSX: SXGC) (ASX: SX2) (OTCQX: SXGCF) (FSE: MV3)

Southern Cross Gold Consolidated Ltd. (TSX: SXGC) (ASX: SX2) (OTCQX: SXGCF), is defining a leading gold-antimony project at the Sunday Creek Gold-Antimony Project, located 60 km north of Melbourne. Sunday Creek is a significant gold and antimony drill discovery in a Tier 1 location, with high-grade drill results including 98 composite intersections exceeding 100 g/t Au from 142.5 km of drilling (including historic drilling). The mineralization follows a "Golden Ladder" structure over 12 km of interpreted strike length, with structures drill tested from surface to 1,200 m depth.

Sunday Creek's strategic value is enhanced by its dual-metal profile. The Company has a critical mineral that the Western world needs. This has gained increased significance following China's export restrictions on antimony, a critical metal for defence and semiconductor applications. Southern Cross' inclusion in the US Defense Industrial Base Consortium (DIBC) and Australia's AUKUS-related legislative changes position it as a potential key Western antimony supplier.

Technical fundamentals further strengthen the investment case, with preliminary metallurgical work showing non-refractory mineralization suitable for conventional processing and gold recoveries of 93% to 98% through gravity and flotation.

With a strong cash position, 2,296 Ha of strategic freehold land ownership, and a large 200 km drill program planned through Q1 2027, SXGC is well-positioned to advance this globally significant gold-antimony discovery in a tier-one jurisdiction, delivering milestone by milestone.

NI 43-101 Technical Background and Qualified Person

Kenneth Bush, Head of Exploration for SXGC, a Member of Australian Institute of Geoscientists and a Registered Professional Geologist in the fields of Mining and Exploration (#10315), is the Qualified Person as defined by the NI 43-101. They have prepared, reviewed, verified and approved the technical contents of this release.

Analytical samples are transported to the Bendigo facility of On Site Laboratory Services ("On Site") which operates under both an ISO 9001 and NATA quality systems. Samples were prepared and analyzed for gold using the fire assay technique (PE01S method; 25 gram charge), followed by measuring the gold in solution with flame AAS equipment. Samples for multi-element analysis (BM011 and over-range methods as required) use aqua regia digestion and ICP-OES analysis. The QA/QC program of Southern Cross Gold consists of the systematic insertion of certified standards of known gold content, blanks within interpreted mineralized rock and quarter core duplicates. In addition, On Site inserts blanks and standards into the analytical process.

SXGC considers that both gold and antimony that are included in the gold equivalent calculation ("AuEq") have reasonable potential to be recovered and sold at Sunday Creek, given current geochemical understanding, historic production statistics and geologically analogous mining operations. Historically, ore from Sunday Creek was treated onsite or shipped to the Costerfield mine, located 54 km to the northwest of the project, for processing during WW1. The Costerfield mine corridor, now owned by Alkane Resources (previously Mandalay Resources) contains two million ounces of equivalent gold (Mandalay Resources Q3 2021 Results), and in 2020 was the sixth highest-grade global underground mine and a top 5 global producer of antimony.

SXGC considers that it is appropriate to adopt the same gold equivalent variables as Mandalay Resources Ltd in its 2024 End of Year Mineral Reserves and Resources Press Release, dated February 20, 2025. The gold equivalence formula used by Mandalay Resources was calculated using Costerfield's 2024 production costs, using a gold price of US$2,500 per ounce, an antimony price of US$19,000 per tonne and 2024 total year metal recoveries of 91% for gold and 92% for antimony, and is as follows:

AuEq = Au (g/t) + 2.39 × Sb (%)

Based on the latest Costerfield calculation and given the similar geological styles and historic toll treatment of Sunday Creek mineralization at Costerfield, SXGC considers that a AuEq = Au (g/t) + 2.39 × Sb (%) is appropriate to use for the initial exploration targeting of gold-antimony mineralization at Sunday Creek.

CriteriaJORC Code explanationCommentary
Sampling techniques
  • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.
  • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
  • Aspects of the determination of mineralization that are Material to the Public Report.
  • In cases where 'industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralization types (e.g. submarine nodules) may warrant disclosure of detailed information.
  • Sampling has been conducted on drill core (half core for >90% and quarter core for check samples), grab samples (field samples of in-situ bedrock and boulders; including duplicate samples), trench samples (rock chips, including duplicates) and soil samples (including duplicate samples).
    Locations of field samples were obtained by using a GPS, generally to an accuracy of within 5 metres. Drill hole and trench locations have been confirmed to <1 metre using a differential GPS.
    Samples locations have also been verified by plotting locations on the high-resolution Lidar maps
  • Drill core is marked for cutting and cut using an automated diamond saw used by Company staff in Kilmore.
    Samples are bagged at the core saw and transported to the Bendigo On Site Laboratory for assay.
    At On Site samples are crushed using a jaw crusher combined with a rotary splitter and a 1 kg split is separated for pulverizing (LM5) and assay.
  • Standard fire assay techniques are used for gold assay on a 25 g charge by experienced staff (used to dealing with high sulfide and stibnite-rich charges). On Site gold method by fire assay code PE01S.
  • Screen fire assay is used to understand gold grain-size distribution where coarse gold is evident.
  • ICP-OES is used to analyze the aqua regia digested pulp for an additional 12 elements (method BM011) and over-range antimony is measured using flame AAS (method known as B050).
  • Soil samples were sieved in the field and an 80-mesh sample bagged and transported to ALS Global laboratories in Brisbane for super-low level gold analysis on a 50 g samples by method ST44 (using aqua regia and ICP-MS).
  • Grab and rock chip samples are generally submitted to On Site Laboratories for standard fire assay and 12 element ICP-OES as described above.
Drilling techniques
  • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.).
  • HQ or NQ diameter diamond drill core, oriented using Axis Champ orientation tool with the orientation line marked on the base of the drill core by the driller/offsider.
    A standard 3 metre core barrel has been found to be most effective in both the hard and soft rocks in the project.
Drill sample recovery
  • Method of recording and assessing core and chip sample recoveries and results assessed.
  • Measures taken to maximise sample recovery and ensure representative nature of the samples.
  • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.
  • Core recoveries were maximised using HQ or NQ diamond drill core with careful control over water pressure to maintain soft-rock integrity and prevent loss of fines from soft drill core. Recoveries are determined on a metre-by-metre basis in the core shed using a tape measure against marked up drill core checking against driller's core blocks.
  • Plots of grade versus recovery and RQD (described below) show no trends relating to loss of drill core, or fines.
Logging
  • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
  • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography.
  • The total length and percentage of the relevant intersections logged.
  • Geotechnical logging of the drill core takes place on racks in the company core shed.
    Core orientations marked at the drill rig are checked for consistency, and base of core orientation lines are marked on core where two or more orientations match within 10 degrees.
    Core recoveries are measured for each metre
    RQD measurements (cumulative quantity of core sticks > 10 cm in a metre) are made on a metre-by-metre basis.
  • Each tray of drill core is photographed (wet and dry) after it is fully marked up for sampling and cutting.
  • The ½ core cutting line is placed approximately 10 degrees above the orientation line so the orientation line is retained in the core tray for future work.
  • Geological logging of drill core includes the following parameters:
    Rock types, lithology
    Alteration
    Structural information (orientations of veins, bedding, fractures using standard alpha-beta measurements from orientation line; or, in the case of un-oriented parts of the core, the alpha angles are measured)
    Veining (quartz, carbonate, stibnite)
    Key minerals (visible under hand lens, e.g. gold, stibnite)
  • 100% of drill core is logged for all components described above into the company MX logging database.
  • Logging is fully quantitative, although the description of lithology and alteration relies on visible observations by trained geologists.
  • Each tray of drill core is photographed (wet and dry) after it is fully marked up for sampling and cutting.
  • Logging is considered to be at an appropriate quantitative standard to use in future studies.
Sub-sampling techniques and sample preparation
  • If core, whether cut or sawn and whether quarter, half or all core taken.
  • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry.
  • For all sample types, the nature, quality and appropriateness of the sample preparation technique.
  • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
  • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.
  • Whether sample sizes are appropriate to the grain size of the material being sampled.
  • Drill core is typically half-core sampled using an Almonte core saw. The drill core orientation line is retained.
  • Quarter and half core is used when taking sampling duplicates (termed FDUP in the database).
  • Sampling representivity is maximised by always taking the same side of the drill core (whenever oriented),and consistently drawing a cut line on the core where orientation is not possible. The field technician draws these lines.
  • Sample sizes are maximised for coarse gold by using half core, and using quarter core and half core splits (laboratory duplicates) allows an estimation of nugget effect.
  • In mineralized rock the company uses approximately 10% of core duplicates, certified reference materials (suitable OREAS materials), laboratory sample duplicates and instrument repeats.
  • In the soil sampling program duplicates were obtained every 25th sample and the laboratory inserted low-level gold standards regularly into the sample flow.
Quality of assay data and laboratory tests
  • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
  • For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.
  • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.
  • The fire assay technique for gold used by On Site is a globally recognised method, and over-range follow-ups including gravimetric finish and screen fire assay are standard. Of significance at the On Site laboratory is the presence of fire assay personnel who are experienced in dealing with high sulfide charges (especially those with high stibnite contents) – this substantially reduces the risk of inaccurate reporting in complex sulfide-gold charges.
  • Where screen fire assay is used, this assay will be reported instead of the original fire assay.
  • The ICP-OES technique is a standard analytical technique for assessing elemental concentrations. The digest used (aqua regia) is excellent for the dissolution of sulfides (in this case generally stibnite, pyrite and trace arsenopyrite), but other silicate-hosted elements, in particular vanadium (V), may only be partially dissolved. These silicate-hosted elements are not important in the determination of the quantity of gold, antimony, arsenic or sulphur.
  • A portable XRF has been used in a qualitative manner on drill core to ensure appropriate core samples have been taken (no pXRF data are reported or included in the MX database).
  • Acceptable levels of accuracy and precision have been established using the following methods
    ¼ duplicates – half core is split into quarters and given separate sample numbers (commonly in mineralized core) – low to medium gold grades indicate strong correlation, dropping as the gold grade increases over 100 g/t Au.
    ½ duplicates – core is split into halves and given separate sample numbers (commonly in mineralized core) – low to medium gold grades indicate strong correlation, dropping as the gold grade increases over 100 g/t Au.
    Washes – washes are inserted post visible gold or >1% visible stibnite to ensure contamination is minimised during the preparation stage
    Blanks – blanks are inserted after visible gold and in strongly mineralized rocks to confirm that the crushing and pulping are not affected by gold smearing onto the crusher and LM5 swing mill surfaces. Results are excellent, generally below detection limit and a single sample at 0.03 g/t Au.
    Certified Reference Materials – OREAS CRMs have been used throughout the project including blanks, low (<1 g/t Au), medium (up to 5 g/t Au) and high-grade gold samples (> 5 g/t Au). Results are automatically checked on data import into the MX database to fall within 2 standard deviations of the expected value.
    Laboratory splits – On Site conducts splits of both coarse crush and pulp duplicates as quality control and reports all data. In particular, high Au samples have the most repeats.
    Laboratory CRMs – On Site regularly inserts their own CRM materials into the process flow and reports all data
    Laboratory precision – duplicate measurements of solutions (both Au from fire assay and other elements from the aqua regia digests) are made regularly by the laboratory and reported.
  • Accuracy and precision have been determined carefully by using the sampling and measurement techniques described above during the sampling (accuracy) and laboratory (accuracy and precision) stages of the analysis.
  • Soil sample company duplicates and laboratory certified reference materials all fall within expected ranges.
Verification of sampling and assaying
  • The verification of significant intersections by either independent or alternative company personnel.
  • The use of twinned holes.
  • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
  • Discuss any adjustment to assay data.
  • The Independent Geologist has visited Sunday Creek drill sites and inspected drill core held at the Kilmore core shed - 11 December 2024 S.Tambanis.
  • The CP & QP, Mr Kenneth Bush has visually inspected the drill core from holes in this release. The drill intersections match both the geological descriptions in the database and the expected assay data (for example, gold and stibnite visible in drill core is matched by high Au and Sb results in assays).
  • In addition, on receipt of results Company geologists assess the gold, antimony and arsenic results to verify that the intersections returned expected data.
  • The electronic data storage in the MX database is of a high standard. Primary logging data are entered directly by the geologists and field technicians and the assay data are electronically matched against sample number on return from the laboratory.
  • Certified reference materials, ¼ core field duplicates (FDUP), laboratory splits and duplicates and instrument repeats are all recorded in the database.
  • Exports of data include all primary data, from hole SDDSC077B onwards after discussion with SRK Consulting. Prior to this gold was averaged across primary, field and lab duplicates.
  • Adjustments to assay data are recorded by MX, and none are present (or required).
  • Twinned drill holes are not available at this stage of the project.
Location of data points
  • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.
  • Specification of the grid system used.
  • Quality and adequacy of topographic control.
  • Differential GPS used to locate drill collars, trenches and some workings
  • Standard GPS for some field locations (grab and soils samples), verified against Lidar data.
  • Downhole surveys are collected by either electronic single-shot, REFLEX EZ-TRAC multi-shot or Imdex/Axis north-seeking gyro or a combination. During drilling, surveys are completed at a maximum of 30m intervals, with multi-shot surveys completed at hole completion or upon request by geologists at 3m intervals during drilling unless ground conditions are unsuitable.
  • The grid system used throughout is Geocentric datum of Australia 1994; Map Grid Zone 55 (GDA94_Z55), also referred to as ELSG 28355. Reported azimuths also relate to MGA55 (GDA94_Z55).
  • Topographic control is excellent owing to sub 10 cm accuracy from Lidar data.
Data spacing and distribution
  • Data spacing for reporting of Exploration Results.
  • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.
  • Whether sample compositing has been applied.
  • The data spacing is suitable for reporting of exploration results – evidence for this is based on the improving predictability of high-grade gold-antimony intersections.
  • At this time, the data spacing and distribution are not sufficient for the reporting of Mineral Resource Estimates. This however may change as knowledge of grade controls increase with future drill programs.
  • Samples have been composited to a 1 g/t AuEq over 2.0 m width for lower grades and 5 g/t AuEq over 1.0 m width for higher grades in table 3. All individual assays above 0.1 g/t AuEq have been reported to two decimal places with no compositing in table 4.
Orientation of data in relation to geological structure
  • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
  • If the relationship between the drilling orientation and the orientation of key mineralized structures is considered to have introduced a sampling bias, this should be assessed and reported if material.
  • The true thickness of the mineralized intervals reported are interpreted to be approximately 55-80% of the sampled thickness.
  • Drilling is oriented in an optimum direction when considering the combination of host rock orientation and apparent vein control on gold and antimony grade.
    The steep nature of some of the veins may give increases in apparent thickness of some intersections, but more drilling is required to quantify.
  • A sampling bias is not evident from the data collected to date (drill holes cut across mineralized structures at a moderate angle).
Sample security
  • The measures taken to ensure sample security.
  • Drill core is delivered to the Kilmore core logging shed by either the drill contractor or company field staff. Samples are marked up and cut by company staff at the Kilmore core shed, in an automated diamond saw and bagged before loaded onto strapped secured pallets and trucked by company staff to Bendigo for submission to the laboratory. There is no evidence in any stage of the process, or in the data for any sample security issues.
Audits or reviews
  • The results of any audits or reviews of sampling techniques and data.
  • Continuous monitoring of CRM results, blanks and duplicates is undertaken by geologists and the company data geologist. Mr Kenneth Bush for SXG has the orientation, logging and assay data.

 

Section 2 Reporting of Exploration Results

CriteriaJORC Code explanationCommentary
Mineral tenement
and land tenure
status
  • Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
  • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.
  • The Sunday Creek Project, previously known as the Clonbinane Project, is covered by the Retention Licence RL 6040 and is surrounded by Exploration Licence EL6163 and Exploration Licence EL7232. All the licences are 100% held by Clonbinane Goldfield Pty Ltd, a wholly owned subsidiary company of Southern Cross Gold Ltd.
Exploration done by
other parties
  • Acknowledgment and appraisal of exploration by other parties.
  • The Sunday Creek project is a high level orogenic (or epizonal) Fosterville-style deposit. Small scale mining has been undertaken in the project area since the 1880s continuing through to the early 1900s. Historical production occurred with multiple small shafts and alluvial workings across the Clonbinane Goldfield permits. Production of note occurred at the Clonbinane area with total production being reported as 41,000 oz gold at a grade of 33 g/t gold (Leggo and Holdsworth, 2013)
  • Work in and nearby to the Sunday Creek Project area by previous explorers typically focused on finding bulk, shallow deposits. Beadell Resources were the first to drill deeper targets and Southern Cross have continued their work in the Sunday Creek Project area.
  • EL54 - Eastern Prospectors Pty Ltd
    Rock chip sampling around Christina, Apollo and Golden Dyke mines.
    Rock chip sampling down the Christina mine shaft. Resistivity survey over the Golden Dyke. Five diamond drill holes around Christina, two of which have assays.
  • ELs 872 & 975 - CRA Exploration Pty Ltd
    Exploration focused on finding low grade, high tonnage deposits. The tenements were relinquished after the area was found to be prospective but not economic.
    Stream sediment samples around the Golden Dyke and Reedy Creek areas. Results were better around the Golden Dyke. 45 dump samples around Golden Dyke old workings showed good correlation between gold, arsenic and antimony.
    Soil samples over the Golden Dyke to define boundaries of dyke and mineralization. Two costeans parallel to the Golden Dyke targeting soil anomalies. Costeans since rehabilitated by SXG.
  • ELs 827 & 1520 - BHP Minerals Ltd
    Exploration targeting open cut gold mineralization peripheral to SXG tenements.
  • ELs 1534, 1603 & 3129 - Ausminde Holdings Pty Ltd
    Targeting shallow, low grade gold. Trenching around the Golden Dyke prospect and results interpreted along with CRAs costeans. 29 RC/Aircore holes totalling 959 m sunk into the Apollo, Rising Sun and Golden Dyke target areas.
  • ELs 4460 & 4987 - Beadell Resources Ltd
    ELs 4460 and 4497 were granted to Beadell Resources in November 2007. Beadell successfully drilled 30 RC holes, including second diamond tail holes in the Golden Dyke/Apollo target areas.
  • Both tenements were 100% acquired by Auminco Goldfields Pty Ltd in late 2012 and combined into one tenement EL4987.
  • Nagambie Resources Ltd purchased Auminco Goldfields in July 2014. EL4987 expired late 2015, during which time Nagambie Resources applied for a retention licence (RL6040) covering three square kilometres over the Sunday Creek Project. RL6040 was granted July 2017.
  • Clonbinane Goldfield Pty Ltd was purchased by Mawson Gold Ltd in February 2020.
  • Mawson drilled 30 holes for 6,928 m and made the first discoveries to depth.
Geology
  • Deposit type, geological setting and style of
  • mineralization.
  • Refer to the description in the main body of the release.
Drill hole Information
  • A summary of all information material to the understanding of the exploration results including a tabulation of the following
  • information for all Material drill holes:
    • easting and northing of the drill hole collar
    • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
    • dip and azimuth of the hole
    • down hole length and interception depth
    • hole length.
  • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.
  • Refer to appendices
Data aggregation methods
  • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high-grades) and cut-off grades are usually Material and should be stated.
  • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
  • The assumptions used for any reporting of metal equivalent values should be clearly stated.
  • See "Further Information" and "Metal Equivalent Calculation" in main text of press release.
Relationship
between
mineralization
widths and
intercept lengths
  • These relationships are particularly important in the reporting of Exploration Results.
  • If the geometry of the mineralization with respect to the drill hole angle is known, its nature should be reported.
  • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g 'down hole
  • length, true width not known').
  • See reporting of true widths in the body of the press release.
Diagrams
  • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.
  • The results of the diamond drilling are displayed in the figures in the announcement.
Balanced reporting
  • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high-grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.
  • All results above 0.1 g/t Au have been tabulated in this announcement. The results are considered representative with no intended bias.
  • Core loss, where material, is disclosed in tabulated drill intersections.
Other substantive exploration data
  • Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.
  • Preliminary testing was reported in January 11, 2024. This established the general metallurgical test procedure for samples from the Sunday Creek deposits and demonstrated the basis for confidence in establishing prospects for economic recovery of contained gold and antimony to three separate products:
    • Metallic gold product by gravity recovery
    • Antimony-gold flotation concentrate
    • Pyrite-arsenopyrite-gold flotation concentrate
  • Testing has now been expanded to include samples from additional zones of the mineral deposits and to refine metallurgical processes. The aim was to improve aspects of antimony concentrate production, maximise gold recovery to a high-grade metallic product, and to further investigate the nature of gold occurrence.
  • The work, conducted by ALS Burnie Laboratories, focused on:
    • Improving selectivity between sulphide minerals in the antimony flotation stage whilst maintaining high overall gold recovery.
    • Further processing of the flotation concentrates, to assess the metallurgical response of contained gold.
    • Mineralogical examination of selected product samples.
  • It was demonstrated that, with appropriate process conditions, high antimony and gold recovery could be maintained whilst rejecting arsenic and iron sulphides in the first flotation stage. The antimony concentrate produced (~50% Sb, <0.2% As) is deemed to be attractive to the smelter market.
  • Recovery of antimony to concentrate varied with feed type, and ranged from 83% to 93% for the samples tested from the antimony rich zones.
  • Additional metallic gold was recovered from the flotation concentrate by gravity separation.
  • The gold grade of the concentrate is a function of the proportion of feed gold associated with arsenic-iron sulphides, the ratio of gold to antimony in the feed, the gold recovered to the metallic gold product, and the flotation rate of gold in the first flotation stage.
  • High overall gold recovery was achieved with all samples tested.
  • Further Work
    • Additional characterization testing across deposit zones
    • Locked cycle testing to confirm overall recoveries
    • Multi-stage cleaning optimization to maximize concentrate quality
    • Pilot plant evaluation of larger samples
    • Process plant design studies targeting Q1 2027 completion
Further work
  • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).
  • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
  • The Company has stated it will drill 200,000 m through 2025 to Q1 2027.
  • See diagrams in presentation which highlight current and future drill plans.
