Solis Announces Additional High-Grade Copper Confirmed at Cinto, Peru

Rhea-AI Summary

Solis Minerals (ASX: SLM) has announced additional high-grade copper mineralization at its Cinto Project in Peru. Recent channel sampling revealed significant results, including 26.5m @ 0.28% Cu (Channel 11), with a high-grade section of 5.4m @1.0% Cu. Previous sampling had shown results of 23.4m @ 0.88% Cu and 16.8m @ 0.52% Cu.

The copper mineralization extends across a potential area of 3km long and 0.75km wide. The project is located 15km southeast of the Toquepala mine, one of Peru's largest copper operations. Four distinct mineralization types have been identified, predominantly in breccias. The company has initiated permitting for drilling scheduled to begin in the second half of 2025.

The project's geological setting along the Incapuquio Fault System is considered favorable for large-scale porphyry copper deposits. Geophysical data from drone magnetometry supports scale potential and highlights new target areas.

West Leederville, Western Australia--(Newsfile Corp. - April 22, 2025) - Latin American focused copper-gold explorer Solis Minerals Limited (ASX: SLM) ("Solis Minerals" or the "Company") is pleased to announce an update on copper mineralisation identified in channel samples at the Cinto Project in Peru.

Chief Executive Officer, Mitch Thomas, commented:

"These results confirm the significant potential at the Cinto Project, where we've substantially expanded Solis' porphyry copper mineralisation footprint. Notably, we're seeing mineralisation styles similar to those at the major Toquepala mine, just 15km away. Geophysical data from drone magnetometry supports scale potential and highlights new target areas. As a stand-alone project, Cinto is a compelling copper porphyry target.

Our on-ground team recently hosted site visits for our technical director Mike Parker and myself across our project portfolio. Visible mineralisation at surface at Ilo Este and Cinto was a highlight. The clear, visible prospectivity in our projects very much aligns with our objective of identifying copper-gold resources that have potential to host large-scale mining in one of the world's leading copper producing regions.

With drilling set to begin at Chancho al Palo³ and Ilo Este this quarter, and Cinto advancing toward drilling in the second half of 2025, Solis Minerals' portfolio of 100% owned projects has incredible potential for discovery of multiple copper-gold resources capable of supporting mining operations."

Summary

Exploration results at Cinto from channel sampling (Table 1) show a continuation of the mineralised breccia zones previously announced on 11 February 2025. A new channel, Channel 11, situated between previously reported Channels 7 and 8, reported 26.5m @ 0.28% Cu, including 5.39m @ 1.0% Cu.

The copper mineralisation encountered at Cinto to date is predominantly in breccias, the major mineralisation host at Toquepala, 15km northwest of Cinto. Four mineralisation types have been identified in distinct zones. Cinto is situated on the major Incapuquio Fault System which favoured the emplacement of intrusions related to large-scale porphyry copper deposits of Toquepala, Quellaveco, and Cuajone (Figure 1). Toquepala is one of Peru's oldest and largest copper producers (200ktpa copper production).

Cinto Project

The Cinto Project consists of six granted tenements totalling 2,700Ha and five applications totalling 2,800Ha in the highly prospective Cenozoic Porphyry Belt of southern Peru, located some 15km to the southeast of the world class Toquepala Copper Mine (Figure 1). Cinto is geologically distinct from the rest of Solis' tenements which are situated in the older Jurassic-Cretaceous Coastal Belt of Peru (Figure 2).

In addition to the rock geochemistry results reported on February 11, 2025, further results of rock and channel geochemistry sampling programs carried out at Cinto in the first quarter of 2025 continue to yield highly encouraging results that confirm porphyry mineralisation over a broad area. Rock samples were collected from outcrops of interest or on a sampling grid, whilst channel samples were continuous samples taken across zones of outcropping mineralisation, usually related to old workings or eroded gullies.

Channels 11 and 12 were sampled in an eroded gully zone between previously reported Channels 7, 8, and 9. Channel 11, situated between previously reported Channels 7 and 8, reported 26.5m @ 0.28% Cu, including 5.39m at 1.0% Cu and 7.19m @ 0.2% Cu (Table 1). Channel 12, a continuation of Channel 11 between previously reported Channels 8 and 9, reported no significant copper mineralisation due to partial cover with barren volcanics.

Field observations at the site of Channels 7-9, and 11-12 (this release), show that the intrusive hydrothermal breccia is massive in nature with undefined limits due to poor exposure. The channel sample results therefore do not represent a true width of mineralisation.

A strong correlation is identified between copper mineralisation defined in the geochemical program and previously reported magnetic low geophysical anomalies⁴ (Figure 4). In the northeast of the licence, all channel samples and the majority of copper-anomalous rock samples fall within a magnetic low of dimensions 3km x 0.75km with the low core having a surface area of 1.75km² creating scope for scale. This magnetic low anomaly is interpreted as being caused by magnetite destruction, a common occurrence in porphyry deposits where late-stage mineralising fluids react with magnetic minerals in a host rock, altering them to non-magnetic mineral species.

Previous Exploration

Prior to Solis Minerals acquiring the Cinto tenements, limited systematic exploration had been completed and there are no records of previous drill programs. Solis Minerals commenced exploration with a WorldView-3 remote sensing survey, followed up by geological mapping. In 2023 and 2024, reconnaissance rock sampling led to the identification of an area of in-situ copper oxide mineralisation in old workings in the northeast of the property. Solis Minerals completed a drone magnetometry survey that identified areas of low magnetic response coincident and extending beyond the reconnaissance mineralisation⁴. Rock and channel sampling was expanded in late 2024 with some 530 samples taken in total. Previous exploration results are summarised in Figures 5 and 6.

Cinto Structural Setting

Cinto sits astride or just south of the regional transcurrent Incapuquio Fault System (Figures 1 & 6). The fault's corridor of influence includes en echelon faults, and subparallel fault structures. In the Cinto area, the fault corridor has an approximate width of 2.5km across its predominant NW-SE strike direction. This fault system is believed to have influenced the emplacement of Late Cretaceous to Early Palaeogene (Cenozoic) granodioritic, dioritic, and monzonitic intrusions as well as related volcanic rocks of the Toquepala Group⁵. The large-scale copper porphyry deposits of Cuajone, Quellaveco, and Toquepala were formed during this intrusive phase (Figure 2) and are associated with, or emplaced within, volcanics of the Toquepala Group.

Cinto Geochemical Sampling 2025

During Q1 2025, 125 rock samples were collected (Tables 1-4). Of these, 102 were outcrop rock samples and 23 were channel samples from 2 separate channels. Channel sampling was carried out in an area of good to continuous outcrop, principally facilitated by gully erosion. The Q1 2025 program complements the 2023/2024² geochemistry and brings the total rock sampling inventory at Cinto to 655 samples.

The 23 channel sample results from the Q1 2025 program are summarised in Table 1 with details in Table 3, Appendix 1.

Table 1: Summary of channel sample geochemical assay results from Cinto Project. Zones highlighted in bold are >0.5% Cu. True length is calculated taking into account the linearity of the sampling line. Sampling was done in an area of poorly constrained massive breccia outcrop and does not reflect true width. For location coordinates of channel samples and all assays, refer Table 3, Appendix 1.

Additionally, 102 rock outcrop samples were analysed. Of these, 62 samples were collected on an approximate 50 x 100m grid over an area of 0.4km2 in the north-east of the Cinto tenements. The remaining 40 samples were collected on an approximate 200 x 200m grid over two areas totalling 1.8km2 in the north-central area of the tenements. The results from these samples (Table 2, Table 4, Appendix 1) show a correlation of copper mineralisation with alteration (low magnetic response areas) around structures (Figure 7). Table 2 shows the highest Cu assays returned in rocks (does not include channel samples) and their geological context.

Cinto Mineralisation Style

Increased mapping and additional sampling in the north-east of the Cinto tenements has identified four porphyry mineralisation styles to date, namely:

- Brecciated andesitic tuffs associated with or invaded by intrusive hydrothermal breccias (Type A);

- Intrusive hydrothermal breccias (Type B);

- Dioritic and monzodioritic intrusions, often with propylitic or argillic alteration (Type C);

- Granodioritic batholith, commonly with chlorite (Type D)

The mineralisation styles are distributed from west to east across the area with Types A and B dominating in higher topographic zones, leading to Type C in fault valleys formed by the Incapuquio Fault, and Type D furthest east in exposed batholith (Figure 8). The position of the mineralisation in the system is high-level (A+B), mid-level (C), to basal (D).

The general geology of the area consists of Toquepala Group volcanic rocks that are coeval (contemporaneous) with porphyry formation and emplacement. Porphyry mineralisation can be assumed to be emplaced into the base of the volcanics at various levels facilitated by the Incapuquio Fault system or its splays. Cover rocks consist of barren Toquepala Group volcanics, often andestic tuffs. Erosion and structural displacement has created a configuration of shallow to deeper mineralisation styles from west to east (A to D) as shown in Figure 8.

Gullies that cut through barren tuffs have locally exposed some high-level mineralisation (igneous hydrothermal breccias and volcanics, Type B and A). Type C, mid-level, intrusive mineralisation appears to be outcropping or in deeply incised areas. Barren tuffs cover much of the area, as reflected in the rock geochemistry program. Isolated basal-type mineralisation in the batholith (Type D) is found in the east of the area in deeply eroded terrain, upthrown, north of a major Incapuquio fault valley. Irrespective of mineralisation type, magnetic lows largely encompass mineralised areas as previously described. Whilst no continuity is currently established, the size of the various mineralisation zones in discontinuous outcrop is commonly up to 500m in length and of unknown width.

In the area of Channel Samples 1-4 (Figure 6), the mineralisation is localised in intrusive hydrothermal breccias (Type B) that are associated with quartz veining forming as a matrix in grossly brecciated and phylically altered units (Type A). Copper oxides are visible in the quartz veining and replacing tuffs in patches. Millimetric size clasts and textures in the veins and wallrocks are characteristic of intrusive hydrothermal breccias.

In the areas of Channel Samples 6-12 (Figure 6), the mineralisation occurs in intrusive hydrothermal breccias (Type B) that have impacted andesitic tuffs of the Toquepala Group. Brecciation consists of quartz veining that separates and cross-cuts angular tuff clasts of roughly 2-10cm size. Alteration includes abundant phyllic alteration and silicification. Copper oxide minerals occur in the quartz veins and also in patches and segregations in the clasts.

The above occurrences both resemble various phases of mineralisation at the Toquepala Copper Mine, some 15km northwest of Cinto, where intrusive hydrothermal breccias are a significant mineralisation host. The geochemistry reveals low to sporadic gold values which also resemble Toquepala. Generally low molybdenum values can be attributed to oxidation.

Results of the technical surveys

Following up on 2024 geophysical programs, the latest (current release) channel sampling and rock sampling geochemical results have:

• Confirmed the presence of porphyry style copper mineralisation in favourable structural locations with analogous characteristics to the nearby Toquepala porphyry.

• Demonstrated the wide footprint of mineralisation and capacity for scale.

• Enabled identification of four porphyry mineralisation styles that will greatly aid design of geophysical (IP) surveys and ultimately drill targets.

• Demonstrated a strong spatial correlation of copper mineralisation with the magnetic low geophysical anomaly that indicates a zone of hydrothermal alteration. Several such areas, particularly to the west of the project, have yet to be evaluated, indicating a potential for further large-scale mineralised systems at Cinto (Figure 7).

Next Steps for Cinto

Based on the geochemistry results, Induced-Polarisation (IP) programs are being planned to define drill targets. A scope of work has been confirmed with a domestic supplier with mobilisation currently being coordinated. Results can be expected in Q2 2025. Drill permitting, including archaeological surveys, will commence with a target of drilling in the second half of 2025.

Solis Minerals will continue to investigate the potential of Cinto by testing the as yet unexplored low magnetic anomalies through a combination of mapping and rock geochemistry. Further areas for IP follow-up and drill target definition are expected to become apparent once all the tenement is explored.

JORC Code, 2012 Edition - Table 1

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 representativity 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 a30 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.	125 rock chip and grab samples were collected in Q1 2025 from outcrops. Of these, 85 samples were collected on an approximate 50 x 100m grid over an area of 0.4km2 in the north-east of the Cinto tenements including two channel samples. Remaining 40 samples were collected on an approximate 200 x 200m grid over two areas totalling 1.8km2 in the north-central area of the tenements. Within these areas, where visible copper oxide mineralisation was observed, further samples were taken off-grid to outline zones of interest. Coordinate position and assay results of each sample are shown in Table 4. The samples are considered to be as representative as possible of the exposure albeit by their nature that chip and grab samples do not reflect the overall grade of any mineralisation encountered. Samples were representatively hand-cobbed to approximately 2.5kg mass for lab submission. These samples complement 530 samples taken previously (see ASX Release dated 10th Feb 2025 ). Within the rock sampling grid, 23 channel samples were taken from 2 separate channels of maximum and minimum field length 26.5m and 13.70m respectively. A total of 40.20m of channels were sampled (field length - see below for true length). Channel samples were taken on visible mineralisation exposures that were created by old (>50 years) small-scale workings or gully erosion. Channel 11 was principally an eroded gully and Channel 12 ended in old workings. Within constraints of practicality, channels were sampled to cross mineralisation strike at a high angle and were designed to represent true widths albeit in the area sampled the mineralisation appears to form a massive outcrop with lesser assumed linear nature. The channel samples were adjusted from sampled length to true length where exposure configuration caused curvature of the channel. Channels 11 and 12 were adjusted in this manner from GIS plans. Channel samples were taken in consistent fashion to maintain representative samples. In areas with old workings, usually more friable, the channels were dug approximately 10-20 cm wide by 10-20cm deep. In areas of natural exposure the channels were chipped to 20-30cm wide by 5-10cm deep. Bulk samples were collected on a tarp. Sample lengths were 2.0m, (one exception at 1.50m). Coordinate position and assay results of each channel sample are shown in Table 3. The coordinates are considered the centrepoint of the channel sample.
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).	No historic or new drilling has been reported in this announcement
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.	No drilling reported herein
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.	No drilling reported in this announcement Rock chip and grab samples were logged and rock type lithologies, oxidation and quantities of and types of mineralisation noted. Channel samples are logged in a similar but continuous fashion to construct a strip log of the channel. All channels were logged, 2 in total, for a total of 40.20m of logging (field length) (100% logged).
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 representativity 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.	Systematic rock channel sampling was taken and separated on a tarp - usually up to 30-50kgs per linear metre. Samples were usually friable rock or chips of <3cm and were coned and quartered to produce samples of 3kgs for lab submission. Tarps and shovels/picks were cleaned after each sampling. Across the whole program, field duplicates were taken and reported excellent correlation. The sample procedure and preparation is considered appropriate for the nature of the base metal mineralisation tested and it's distribution throughout the sample. Rock chip and grab samples taken were to be considered of appropriate size and representativity to ascertain if copper and or precious metal mineralisation is present at the outcrops.
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.	All rock chips were assayed by ALS in Lima. Methods used were total assay of sample: Preparation PREP31 Analysis Au-AA23 and ME-ICP61 Cu OG-62 for overlimit Cu >1% Pb OG-62 for overlimit Pb >1% Zn OG-62 for overlimit Zn >1% Ag OG-62 for overlimit Ag >100ppm OREAS standards, blanks, and field duplicates were inserted at appropriate intervals and reported within required 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.	All Solis data is verified by the Competent Person. Channel sample intersections have been checked by alternative company director with prerequisite experience. All data is stored in an electronic database and sample rejects are stored in company warehouses. Competent Person and company CEO have visited the site and observed sampling techniques and quality control. Channel sample intersections and widths were established as per field layout adjustments.
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.	All sample locations were captured using a handheld GPS in WGS84 19S. Rock and chip samples are points. Channel sample intervals have their centrepoint as their GPS location.
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.	No set sample spacing or pattern has been applied due to the preliminary nature of the sampling programme. Exposures of mineralisation were tested where found and not on a regular pattern. The distribution of the mineralisation allows commentary on potential scope of mineralisation but does not imply continuity.
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 mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.	Channel Sample orientation was designed to cross mineralisation at a high angle where possible and appropriate in the exposures. The area in question is part of a more massive outcrop, only partly exposed by gully erosion, and exhibits little local structural control. No bias has been introduced in current drilling and sampling.
Sample security	The measures taken to ensure sample security.	All samples are bagged onsite under supervision of Solis staff, all bags are then sealed and couriered to the relevant laboratories with all relevant submission documentation. All samples once received are logged into the lab and notice of each sample received is sent and cross checked with sample dispatch.
Audits or reviews	The results of any audits or reviews of sampling techniques and data.	There have been no detailed external audits or reviews undertaken. Solis has conducted an internal technical review and site visit by the Competent Person and the company CEO.

 

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section)

Criteria	JORC Code explanation	Commentary
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.	Cinto mineral tenure in Peru is currently in good standing. A recent (January 2025) application to the north of the current tenure is under review. There is no guarantee this area will be granted and it is not material to this release. Community in the area is working under an access agreement with Solis.
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties.	The Cinto property has had no systematic exploration carried out by previous owners No records of previous drilling exist in the mining ministry.
Geology	Deposit type, geological setting and style of mineralisation.	The area is well-known for the occurrence of porphyry Cu deposits. Particularly Toquepala mine 15km northwest in similar geology and structural setting. Cenozoic intrusives have been emplaced in coeval volcanics with alteration and mineralisation to produce bulk mineable porphyry Cu deposits. Low gold, moderate Mo. Igneous hyrothermal (phreatic) breccias are commonly mineralised at Toquepala. This style of mineralisation is being observed at Cinto.
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.	No drillhole data is reported in this release

 

Criteria	JORC Code explanation	Commentary
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.	Individual Channel Samples were treated as continuous intersections and grades calculated using weighted average techniques. Total overall channel grades were reported. Subsequently higher grade included sections, if present, were reported separately. Selection was made on Cu grade cut-off of 0.1% Cu where practical. Other metal cut-offs coincided or were less distinct than Cu. Individual lower grade results were maintained in higher grade intersections where geological continuity was deemed appropriate. Channel 11 example (Cu only) 0.00- 29.50m (26.50m true length) @0.28% Cu - total 0.00-6.00m (5.39m true length) @ 1.00% Cu - included 10.00-18.00m (7.19m true length) @ 0.20% Cu - inc.
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').	The area channel sampled in this release forms part of a more massive mineralised system only partly exposed by gully erosion. True width not known.
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 location of sampled outcrop and channel samples. GPS coordinates of Channel Samples are provided in Table 3. GPS coordinates of rock and chip samples are provided in Table 4.
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.	Assay results for Au, Ag, Cu, Mo, Pb and Zn are presented in total for work related to this release.
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 Company is not aware of any other substantive exploration data relevant to its activities that has not been previously reported and referenced in this release.
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.	IP surveys are planned on the existing channel sample results. Untested areas will be mapped and channel sampled if appropriate. Further IP surveys could be planned. All programs are designed to delineate drill targeting.
