Solis Minerals Ltd.: Solis Bolsters Copper Landholding in Peru

HIGHLIGHTS

• New applications cover 6,400 hectares of highly prospective copper ground across a coastal belt located directly between Ilo Norte and Ilo Este

• Areas were previously held by Anaconda Copper. Ground visits indicate the area has received limited exploration

• Total of 43,500 hectares pegged, mostly in the coastal belt, establishing Solis as a significant landholder in a highly prospective and emerging belt with porphyry copper potential

• Two drill permit applications now underway over Ilo Este and Ilo Norte (Chancho al Palo). Cinto application in planning phase

• Copper mineralisation in association with silicification and alteration identified outcropping at surface on new application areas

• Follow-up mapping and initial geophysical studies to commence immediately

• Solis continues to review potential acquisitions in various jurisdictions and commodity spaces with a focus on copper and lithium projects which are drill ready or with mineralised systems already identified

West Leederville, Western Australia--(Newsfile Corp. - May 10, 2024) - Solis Minerals Limited (ASX: SLM) ("Solis" or the "Company") is pleased to announce an update on recent applications for new copper exploration licences in Peru. Solis has successfully applied for a 6,400-hectare package comprising of seven licences of largely underexplored exploration areas in a highly prospective coastal belt, which were pegged on the 2nd of May (see Figure1). The areas were previously held by Anaconda Copper. Field visits by Solis teams indicate minimal ground exploration has been carried out in recent times.

The Company now holds a significant landholding of 43,500 hectares principally along a coastal belt bounded to the west by batholiths of Jurassic and Cretaceous age (see Figure 2). Based on the outcropping porphyry copper mineralisation at Ilo Este, Solis considers that the eastern margins of the batholiths represent highly prospective areas for porphyry copper occurrences emplaced in volcanic or volcaniclastic rocks.

Executive Director, Matthew Boyes, commented: "We are very pleased to further bolster our portfolio through the addition of a large land package containing highly prospective copper exploration ground in Peru. Solis is building a compelling portfolio of exploration properties in an underexplored porphyry belt, with excellent access and existing infrastructure. Drill permits are advancing as quickly as possible in conjunction with our ongoing non-invasive exploration efforts, preparing us to commence drilling once all necessary approvals are obtained and first drill sites are finalised.

"Solis continues to review and progress potential acquisitions in the copper and lithium space across targeted areas of South America and has two teams dedicated to the evaluation process, which is now bearing significant fruit. In the next 6-12 months will see advancements across our pipeline of copper exploration projects in Peru as we continue to look to add to our Brazilian portfolio of lithium properties."

New Applications: Site Visits

Solis' geologists have visited the area of recent applications and identified alteration and copper mineralisation1 in outcrops 8km north-west along strike and in a similar geological setting to known porphyry-style mineralisation at Ilo Este (see Figures 3 & 4 below).

¹The presence copper oxide samples indicates a mineral species only and should not be considered a substitute for analytical results. Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analysis where concentrations or grades are the factor of primary economic interest

The copper mineralisation identified, and its associated alteration, is considered a "pathfinder" exploration indicator for the potential presence of associated porphyry copper mineralisation in the tenements. Such mineralisation and alteration do not guarantee the presence of associated porphyry mineralisation and thus the significance of the images and estimates are strictly in the context of exploration potential.

The mapping crews are now mobilising to site to systematically cover the entire tenement package and identify areas of highest prospectivity. Low-cost drone magnetic studies in conjunction with remote sensing data interpretation will be carried out and followed up with Induced Polarisation (IP) studies over areas of interest to identify and evaluate primary drill targets.

Drill permitting

Both Ilo Este and Ilo Norte have been recently covered by magnetic and IP surveys that have identified drill targets and drill permitting to test these targets is underway.

Community engagement has commenced at Cinto as part of the process to advance the drill permitting over the project area. Cinto is located 15km SE of the major Toquepala Cu porphyry deposit in northern Tacna which has seen many benefits from the mining canon associated with existing mines.

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.

• Rock chip and grab samples were taken from outcrop which exhibited visible copper oxide mineralisation, the samples are considered to be as representative as possible of the outcropping although they are grab samples and not representative of the body of mineralisation as a whole.

• Chanco al Palo Induced Polarisation survey (IP).. Equipment used are: Receptor RX,GDD/ Model GRx8-32-16ch; Transmitter TX 11, model Walcer KW 10; and Generator model 01 Honda EG6500CX 24 HP. Acquisition parameters:

parameter	mode of acquisition
measurements	time domain
electrode config	PDP (multidipole)
dipole extension	100 m
separ'n factor	10
measurement windows	20
delay time	2
Stacks	10
Reps	2
measured Vp range	1 to 5582.4 mV
injected current intensity (mA):	0 to 1990 mA

Ilo Este magnetometry survey sample regime described in the body of this release.

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).

• All historical drilling carried out at Ilo Este and Ilo Norte has been completed using diamond drilling at NQ core diameters

• 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 samples are logged and rock type lithologies, oxidation and quantities of and types of mineralisation noted

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.

• No drill core or systematic rock channel sampling is reported in this announcement

• Rock chip samples taken are to be considered of appropriate size and representativity to ascertain if copper and or precious metal mineralisation is present at the discovered outcrops, follow up systematic sampling will occur only a granted EIA and permit is obtained to undertake ground disturbing activities.

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.

• No new assay results are published in this release

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. All data is stored in an electronic Access Database.

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 samples and historic drill hole collar locations were captured using a handheld GPS and DGPS.

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.

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.

• No drilling data is reported in this announcement all historic drill holes have been designed at all times to cut the orientation of interpreted and mapped outcropping mineralisation perpendicular to strike of the interpreted structures as to accurately as possible estimate the true width of the target bodies.

• 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 of the available geological and other publicly available data.

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.	All mineral tenure in Peru is currently in good standing a full table of tenements currently under application and which have been granted is included in this release as APPENDIX 1 "Mining concessions table"
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties.	Significant exploration has been carried out by the Company and previous owners on Ilo Este and Ilo Norte tenement packages and all work has been previously publicly disclosed in previous ASX announcements. Minimal historical exploration is believed to have occurred on the recent applications referred to in the announcement.
Geology	Deposit type, geological setting and style of mineralisation.	Prospective potential mineralisation is interpreted to be hosted along the eastern margin of the coastal Cretaceous batholith, porphyry style mineralisation has the potential to form along this major regional trend Peru- Prospective potential IOCG and porphyry copper-gold deposits.
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.	No data aggregation was used in reported exploration results.
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').	No drillhole or intercept data is reported in this announcement
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 including GPOS coordinates on local projection
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.	No assay results were reported in this announcement
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.
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 Priority for Solis is the EIA and drill permitting which will progress on the Chancho al Palo and Ilo Este assets throughout the year, Solis will commence drill permitting processes at Cinto and advance where possible utilising no invasive techniques on all new applications areas
