Copper Sulphides Present over 250m in Hole 3

Mostazal Copper Project, Chile

  • Third diamond hole continues to demonstrate a very large copper system has been discovered at Mostazal, with the first three diamond holes intersecting 250m-444m wide mineralised zones:
    • 362m copper mineralised zone (from surface) in hole #1
    • 444m copper mineralised zone (from surface) in hole #2
    • +250m copper mineralised zone (from 256m) in hole #3
  • The scale of the surface "manto" copper system has been considerably enhanced by Solis' early drilling.
  • Plans underway to expand the drilling program based on exceptional early drilling success.
  • Assay results from samples are expected in March.
  • Solis to verify historical drilling of the area to assist in establishing a JORC / NI 43-101 Mineral Resource for the surface manto copper system.

Vancouver, British Columbia--(Newsfile Corp. - February 24, 2022) - Solis Minerals Ltd. (ASX: SLM) (TSXV: SLMN) (FSE: 08W) ("Solis Minerals" or "the Company") is pleased to provide further updates in relation to the current diamond drilling campaign at the Company's Mostazal Copper Project in Chile ("Mostazal" or "the Project").

Drilling of the Company's third diamond hole MODD003 is now complete, and logging indicates that the hole has potentially intersected a large, deep copper sulphide mineralisation system of over 250m in thickness, with the field team logging pyrite, chalcopyrite, bornite and chalcocite sulphides occurring as amygdales, disseminations, fracture fillings (Figure 1), or in veinlets throughout this zone. The significance of this sulphide mineralisation is under assessment by the Company's geology team, with detailed logging underway and assays yet to be received.

Hole MODD003, a deep vertical hole (drilled to 528m) to the southeast of the previous two holes drilled by the Company, was designed to test a broad IP geophysical target which the Company has interpreted to represent a potential feeder system for the widespread near surface manto copper mineralisation (Figure 2 and Figure 3).

CEO Jason Cubitt commented:

"Drilling of our initial campaign of diamond holes at Mostazal is progressing very well. We have intersected widespread copper sulphide mineralisation in all three holes completed to date, with our latest hole MODD003 the deepest hole drilled at the project thus far.

"We are working to understand the significance of the over 250m sulphide zone in MODD003 and, while we have not yet seen the typical alteration system that we would expect to see associated with our original porphyry target, we are extremely encouraged by the significant size of the mineralisation system we have intersected. The addition of detailed down hole geophysical data together with the assay results from sampling of this core will be required to better understand the extent of the mineralised system at Mostazal. The Company is also planning to conduct Induced Polarization (IP) and/or Magnetotellurics (MT) geophysical surveys down to 500m depth or more to better assist in the hunt for the main feeder system.

"These first drill holes were designed to test the near surface manto-style mineralisation encountered in the historical drilling, and our logging has confirmed the presence of widespread alteration and disseminated copper sulphide mineralisation throughout all three holes completed so far.

"The drill rig has now moved onto MODD004, our last planned hole of this initial phase of drilling. This drillhole is targeting a high-tenor copper-in-soil anomaly to the east of the main manto mineralisation and mining area and may represent the eastern extension of the known mineralisation or the surface expression of a separate mineralised system below the main manto stacked lenses."

Preliminary assessments of the core from MODD003 show copper sulphides over an interval of approximately 250m starting from a depth of approximately 270m, which appears to correlate with the core of the modelled geophysical IP chargeability anomaly (Figure 2).

Similar to holes MODD001 and MODD002, sulphide mineralisation in MODD003 comprises chalcopyrite, chalcocite+/-bornite occurring as amygdales, disseminations, fracture fillings or in veinlets throughout the sulphide zone. Final mineralised intervals remain to be defined based on pending assay results.

The Company is currently engaged in discussions with local down-hole geophysical contractors in Chile in order to undertake a detailed physical property survey. This data will assist the Company in matching the logged lithologies and sulphide mineralisation to the surface IP response. This data in conjunction with the final assay results will enable the development of a detailed model for the observed mineralisation.

Lithologies intersected in MODD003, were again similar to those in MODD001 and MODD002 with a series of altered (haematite/chlorite/albite), amygdaloidal to fragmental porphyritic andesites throughout the hole; with a zone of approximately 20m containing a series of fine grained, locally highly fractured micro-diorite intrusive dykes from 344m (Figure 1).

Drilling has now commenced on MODD004 located to the east of the Company's previous holes, where existing surface geochemistry has highlighted a large high-tenor copper-in-soil anomaly (Figure 3 and Figure 4). Recent reconnaissance of this area has confirmed the presence of artisanal mining in the area, with a number of separate manto lodes being exploited. Despite these obvious signs of mineralisation, this eastern area has remained relatively untested by previous explorers.

Figure 4: Mostazal Copper Project - copper-in-soil contours and drill collar locations

To view an enhanced version of Figure 4, please visit:

This area lies well to the east of the main mining area at Mostazal and may be interpreted to potentially represent the eastern extension of the known manto system, or the surface expression of a separate deeper manto system below the main stacked manto lenses being exploited by artisanal miners. MODD004 has a planned depth of up to 500m and will further test the near surface manto environment as well as the potential blind system at depth.

While the Company is waiting for assay results from this initial phase of drilling, a program of detailed structural surface mapping and relogging of the historical drill core will be initiated, with the aim of developing a more robust geological model for the extensive near surface manto copper mineralisation and supporting the estimation of a maiden JORC Resource at Mostazal.

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section)


JORC Code explanation


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 Mostazal Copper Project is located in the commune of Diego de Almagro, in the Chañaral Province of the Third Atacama Region, Chile approximately 80km northeast of the city of Copiapo.
  • The Mostazal Copper Project consists of eight Exploitation Mining Concessions covering an area of 1,317 ha that were constituted in accordance with the Chilean mining Code 1993.
  • The eight concessions are currently 100% owned by a series of legal Mining Companies (Sociedad Legal Minera), each of which are owned by two shareholders, who are also the owners of Sociedad Legal Minera Mostazal.

Exploration done by other parties

  • Acknowledgment and appraisal of exploration by other parties.
  • Sociedad Legal Minera Mostazal completed reconnaissance sampling and mining activities at the project between 2005 and 2008.
  • Galilea Minerals conducted trench and outcrop sampling in 2008 and produced an exploration target for the M-01 mineralised lens based upon previous geological mapping and surface sampling.
  • IMT Exploraciones completed soil, trench and outcrop sampling, diamond drilling, and ground magnetic and induced polarization geophysical surveys between 2011 and 2013.
  • APGC Corp Chile Spa produced a foreign estimate for the Mostazal Copper Project in 2015 using the diamond drilling data, surface sampling and mapping.
  • Santiago Metals Limitada completed geological mapping over the project area in 2016.


  • Deposit type, geological setting and style of mineralisation.
  • The Mostazal Copper Project area consists of fine grained to porphyritic andesites lava flows and breccias of the Jurassic - lower Cretaceous age Sierra Fraga Formation, that are locally interbedded with volcaniclastic sediments. The andesites are intruded by a series of dacite porphyry dykes of Paleocene to Eocene age that typically trend northeast - southwest. The western and southeastern portions of the project area covered by late-stage Tertiary Atacama gravels with thicknesses ranging from a few metres to a few tens of metres. More recent Quaternary age sediments including sand, gravel, colluvium, and silt cover occurs throughout the project area.
  • Mineralisation identified at the Mostazal Copper Project consists of several stacked stratified and discontinuous copper-silver (Cu-Ag) mineralised lenses or 'mantos' within the andesitic volcanic rocks that strike to the north-northwest and dip to the west, subparallel to the host andesites flow banding.

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
    • 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.
  • A summary of the current Mostazal drilling data/ hole locations is included in Table 1 of this document.

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.
  • Intersection have been calculated as length weighted averages.
  • Selected intersections are reported above a nominal intersection grade cutoff of >0.5% Cu, with a maximum of 3m of internal dilution.
  • No metal equivalent values 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').
  • Calculated intersections are reported as down-hole widths. There is insufficient data at this to enable to calculation of true width intersections.


  • 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.
  • All analytical results for copper and silver from historical programs have been reported.
  • Assay results for Solis Minerals' drilling are pending.

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.

  • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
  • Solis Minerals will undertake extensive validation and field confirmation of the various targets identified from the historical data at the Mostazal Copper Project.
  • A comprehensive work program for the Mostazal Copper Project has been proposed and will include additional diamond drilling, relogging and sampling of the existing diamond drill core, geological mapping and down-hole geophysics.
  • Solis Minerals is currently undertaking diamond drilling at Mostazal.
