October 12, 2022 9:24 AM EDT | Source: Solis Minerals Ltd.
- Seven tenements granted in the highly prospective southern Peruvian Copper belt, southeast of world class Toquepala Au/Ag/Cu/Mo Porphyry Mine.
- Solis' new Cinto Project straddles the regional scale Incapuquio Fault system, and is interpreted to be similar rocks that host Toquepala, 15km to the northwest.
- Worldview-3 remote sensing data and alteration interpretation being completed over key Solis' Peruvian projects - indentifying new drill targets at Ilo Este.
- Field check of highlighted anomalies and detailed geological mapping to commence immediately in preparation for drill testing.
Vancouver, British Columbia--(Newsfile Corp. - October 12, 2022) - Solis Minerals Ltd. (ASX: SLM) (TSXV: SLMN) (FSE: 08W) ("Solis Minerals" or "the Company") is excited to announce it has received confirmation of grants for a series of largely contiguous tenements totalling 3,200ha in the highly prospective southern Peruvian Copper belt, located some 15km to the southeast of the world class Toquepala Au/Ag/Cu/Mo Porphyry Mine (Figure 1 and Appendix 1). The new project will be called the Cinto Project.
The Company has completed the initial compilation of available geological and other data sets over the area, including the acquisition of new remote-sensing satellite data (comprising the Worldview-3[1] platform, amongst others) covering Cinto and Solis' other Peruvian copper projects. Specialist consultant interpretation of this new satellite data has highlighted several priority zones of favourable alteration - particularly at Ilo Este- which has never been tested. Field geological teams will mobilise shortly to undertake detailed field checking, mapping and systematic sampling of the highlighted alteration anomalies in preparation for drill testing. Detailed Worldview-3 data has been acquired over Cinto and is being processed.
CEO Jason Cubitt commented:
"This is an exciting development for Solis shareholders as the Cinto Project offers an opportunity to be the first exploration company to use modern exploration techniques on a staked area, located near one of Peru's largest copper producers, Toquepala mine[2]. With the same major structural controls, and similar rock type and age to Toquepala (57 Ma - 57 million years), we intend to advance this project to a drill-ready stage and offer Solis shareholders exposure to another world-class target in Peru's Southwest copper belt. The Company remains fully funded for this year's field season."

Cinto Copper Project
The northern permits are underlain by igneous rocks of the Cretaceous Toquepala Group and the late Cretaceous-early Tertiary batholith related to the Toquepala porphyry mine some 15km to the northwest.
The regional Incapuquio fault crosses the permits and the underlying igneous rocks are covered by recent sediments, generally south of the fault and increasing in thickness to the southwest.
Several zones of hydrothermal alteration in the concessions are noted in published geological maps. The Company has recently acquired Worldview-3 satellite imagery to assist in rapid delineation of priority areas which will be followed up with geological mapping and rock sampling. The satellite data is currently being processed. Potential drill target identification would initiate permit applications for first-pass drill programs.
Ilo Este Copper Project
The Ilo Este (east) Project comprises four contiguous tenements covering an area of approximately 3,200ha (Figure 2). They are located about 110km northwest of the town of Tacna (Appendix 1).

Exploration undertaken by previous owners at Ilo Este included 12 reverse circulation (RC) drill holes (2000) and 12 diamond drill holes (2014-16), which were successful in identifying copper-gold mineralisation and interpreted to be part of a Cu-Au porphyry system. Mineralisation is differentiated into two types:
1) Oxide zone - green copper oxide minerals (brocanite, atacamite, malachite, neocite, hematite and manganese oxides) with carbonate staining that occurs across both the southern and northern intrusion belts and occurring to depths of approximately 80m.
2) Hypogene mineralisation - copper sulphides (chalcopyrite-bornite-pyrite) occur as disseminations, in fractures and within quartz veins that occur as a random stockwork within porphyritic granodiorite and porphyritic quartz diorite of the northern intrusive belt.
Although it is thought that the parts of llo Este porphyry system may have been deeply eroded down to the potassic zone, there remains the potential to discover higher grade mineralisation in areas of the porphyry that have been less eroded as well as a lower-grade orebody within the remnants of the porphyry. There is also potential for the intrusive belts to continue under cover to the south and east and to have been offset by a major fault (the Chololo Fault) striking to the northeast that could have offset the upper portion of the porphyry. This upper part could potentially host a higher grade phyllic zone of mineralisation.

The Company has recently undertaken Worldview-3 satellite imagery studies and is interpreting the data. Based on initial results indicating untested alteration, it is envisaged that further areas for exploration north of the Chololo fault (Figure 4) will be subject to geological ground mapping, rock sampling, and renewed alteration domain interpretation. South of the Chololo fault, in areas of recent geological cover, a ground magnetic geophysical survey will be undertaken in areas viewed to contain favourable underlying structural architecture to host porphyry-style intrusives. These programs, combined with data from previous drilling, will allow drill planning to proceed in the coming months and permitting to be initiated.

Ilo Norte Copper Project
The Ilo Norte Project area (Figure 5) consists of eight Mining Concessions covering a total area of 7,700ha approximately 20km northeast from the Pacific coastal town of Ilo, in the Ilo Province, Department of Moquegua of Sothern Peru (Appendix 1).

The geology of the llo Norte Project area consists of andesitic pyroclastics, andesitic volcanics belonging to the Chocolate Formation and younger Quaternary cover sediments (Figure 6 and Appendix 1).
Exploration undertaken by previous owners at Ilo Norte included eight RC holes (2011) and 16 diamond holes (2014). Mineralisation encountered at llo Norte is interpreted to be part of an IOCG-type deposit contained within the highly altered andesitic volcaniclastics of the Chocolate Formation. Contact metamorphism and metasomatism have produced at least five phases of widespread development of mostly lentiform economic mineral assemblages including copper, gold, silver, zinc and minor cobalt.

The Company is planning to acquire Worldview-3 satellite data at Ilo Norte in the coming months when climatic conditions are more favourable. This will augment the planning of the exploration programs which will be principally based around extending ground magnetics surveys over cover, and IP surveys where geological and access condition allow in the west of the area. This data, combined with previous drill results and structural interpretation, is expected to assist planning of future drilling.
Proposed Work Program
Cinto: Process Worldview-3 data, identify zones of interest. Mapping, prospecting leading to identification of potential drill targets. Initiate drill permitting leading to potential drill programs.
Ilo Este: Follow-up field visits to newly identified alteration areas. Mapping and prospecting leading to identification of potential drill targets (0-3 months). Follow-up south of regional fault with ground mag survey for additional targets. Initiate drill permitting leading to potential drill programs in 2023.
Ilo Norte: Acquire Worldview-3 satellite imagery (0-3 months). Follow-up with field visits. Complete IP and ground mag surveys where practical. Initiate drill permitting leading to potential drill programs in 2023.

APPENDIX 2
JORC Code, 2012 Edition - Table 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
| Criteria | JORC Code explanation | Commentary |
| 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 mineralisation 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 mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.
| - Sampling across the Ilo Este and Ilo Norte projects has included rock chip sampling from trenches, and rock outcrops, and reverse circulation (RC) and diamond drilling. There is no record of previous exploration at the Cinto Project.
- There is no detailed record of how outcrop or trench chip sampling was completed or the size of the samples.
- RC drilling was completed by Peruvian Latin Resources at Ilo Norte (8 holes for 2,690m completed in 2011) and Rio Tinto at Ilo Este (12 holes for 2,128m completed in 2000).
- Apart from collar locations there are no other records available for the Rio Tinto drilling.
- The RC holes completed by Peruvian Latin Resources had 1,345 samples collected over 2m intervals.
- Diamond drilling was completed by Peruvian Latin Resources at Ilo Este (3 holes for 2,073m completed in 2014-15) and Compania Minera Zahena SAC at both Ilo Norte (16 holes for 12,658 m completed in 2014) and Ilo Este (9 holes for 5,322m completed in 2015-16).
- Diamond core was sampled nominally on 2m (Peruvian Latin Resources) or 3m (Compania Minera Zahena SAC) intervals.
|
| 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).
| - Reverse circulation samples were collected from a rig-mounted cyclone in large plastic bags before being split down to a 4-5kg sample using a 2-tier riffle splitter and then placed into calico bags for despatch to the lab. There is no record of the bit type used for either of the RC drilling programs but the hole completed by Peruvian Latin Resources used 5½ inch bit.
- Diamond drill holes completed by Peruvian Latin Resources at Ilo Este were initially drilled as PQ size (85mm core diameter) to depths varying between 87-109m and were then drilled at HQ size (63.5mm core diameter) until the end of hole. All the holes were completed using a standard tube.
- Diamond drill holes completed by Compania Minera Zahena SAC at Ilo Este were drilled as HQ size (63.5mm core diameter) until the end of hole. All the holes were completed using a standard tube.
- Diamond drill holes completed by Compania Minera Zahena SAC at Ilo Norte were drilled using a combination of HQ size (63.5mm core diameter), NQ (core diameter 47.6mm) and in one drill hole BQ (core diameter 36.5mm) for the last 88m. All the holes were completed using a standard tube.

| - RC samples were collected from a rig-mounted cyclone in large plastic bags before being split down to a 4-5kg sample using a 2-tier riffle splitter. The splitter was cleaned with compressed air between each sample. All the samples were recorded as dry.
- Diamond core was sampled by company technicians under supervision of company geologists using a diamond saw to cut along the axis of the core taking care to representively split any visible mineralisation. Half core samples over two or three-metre intervals were bagged for dispatch to SGS laboratories in Peru. (SGS del Peru S.A.C laboratory in Arequipa for sample preparation and then to the SGS laboratory in Lima for analysis).
- Laboratory sample preparation consisted of weighing the samples upon receipt, crushing the samples so 70% <2 mm, splitting off approximately 1,000g of sample and then pulverising the coarse split to 85% passing 75µ.
- Laboratory sample preparation for diamond drill samples consisted of jaw crushing the samples to a 1/4 inch and then riffle split to obtain 200-250g for pulverising.
- Blanks and field duplicates were inserted at a rate of approximately 1 in 40 to 1 in 50 samples each and certified reference standards were inserted approximately 1 in 20. Laboratory duplicates were also undertaken approximately 1 in 40 samples.
|
| 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.

- dip and azimuth of the hole
- 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.
| - N/A no new drilling data is included in this report
|
| 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.

- No cut-offs have been applied when reporting of mineralised intersections.
- The average copper, gold and silver grades reported for each mineralised intersection include both mineralised and non-mineralised samples.
- No metal equivalents have been used.
|
| Relationship between mineralisation widths and intercept lengths | - These relationships are particularly important in the reporting of Exploration Results.
- If the geometry of the mineralisation 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').
| - N/A no new drilling data is included in this report.
|
| 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 Company has included various maps and figures showing the sample results and geological context.
|
| 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 avoiding misleading reporting of Exploration Results.
| - N/A no new results are included in this report.
|
| 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.
| - The mineralised intersections are reported in context with supporting geological, geochemical and geophysical data at each deposit.
|
| 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).

[1] The Worldview-3 satellite collects multispectral data in the visible and near infrared (VNIR) and shortwave infrared (SWIR) wavelengths. The eight VNIR bands have resolution of 1.24m and the eight SWIR bands have resolution of 3.7m. VNIR data are most useful for highlighting iron-bearing phases like the mineral goethite while the SWIR data are most useful for mapping hydrous phases like the minerals muscovite and kaolinite. Combining these multispectral results with geology and other data provides a powerful exploration tool.
