Solis Minerals Announces: Anomaly Confirms Drill Target Zone During IP Study at Ilo Este, Peru

HIGHLIGHTS

• The Induced Polarisation (IP) geophysical study at Ilo Este Porphyry Copper (Cu) project has identified a large high magnitude chargeability anomaly.

• The IP anomaly located at contact with previously identified magnetic anomaly.

• Combined geophysics and site geology result in confirmation of a highly prospective large-scale untested drill zone.

• Surface mapping and sampling identifies areas of potassic altered porphyritic microdiorites with associated copper oxides (Malachite).

• Drill site selection is underway and drill permitting processes initiated.

West Leederville, Western Australia--(Newsfile Corp. - December 14, 2023) - Solis Minerals Limited (ASX: SLM) ("Solis" or the "Company") is pleased to announce the completion of the Induced Polarisation (IP) study at its Ilo Este project Peru.

Executive Director, Matthew Boyes, commented:

"Ilo Este is shaping up to be a compelling porphyry copper target with the successful identification by our team in Peru of an extremely prospective high chargeability anomaly located in close proximity to the previously identified large magnetic anomaly."

"The drill programme planning has already commenced to allow us to test these anomalies with drilling next year. A semi-detailed environmental impact study will now be undertaken to select drill sites to test these exciting targets. Historical drilling returned highly anomalous values for copper and gold but clearly missed the highest priority target areas generated in this newly acquired IP data combined with reprocessed magnetic data."

"Surface mapping and reconnaissance programmes is ongoing on all our Peruvian land package. A continuous process of project evaluation is underway with a view to growing our already large, quality exploration portfolio."

Ilo Este Project

Solis has advanced exploration at the Ilo Este project in Peru. Based on Worldview-3 satellite imaging acquired in late 2022, exploration has focused on altered areas that have not been subject to any drilling (Figure 7). Detailed geological mapping in this zone combined with rock geochemistry surveys1 identified an area of strong potassic alteration in porphyry microdiorites with commonly associated malachite (copper oxide mineral).

Magnetic Vector Inversion Analysis

A Magnetic Vector Inversion (MVI) of 2014 ground magnetometry survey data was undertaken in August 20232. The MVI, carried out by Fathom Geophysics, utilised modern software and filters which outlined a magnetic susceptibility anomaly in the south of the area identified as the Southern Magnetic Anomaly (see Figure 1). Other magnetic susceptibility anomalies in the permits, specifically the Northern Magnetic Anomaly, have been drilled by previous explorers and shown to be magnetite-rich areas associated with porphyry copper style mineralisation and alteration. Subsequent to the MVI results, the Southern Magnetic Anomaly was targeted by an Induced Polarisation (IP) survey in September 2023 (see Figures 1 & 7). The IP survey of total line length 10.5km was conducted in September 2023 by Real Eagle Explorations EIRL of Lima.

The high chargeability anomaly (>20mV/V) has dimensions of 1,250m length and 200-400m width. It is detectable from approximately 100m below surface to 500m below surface (the base of the survey - see Figures 3 & 4). The magnetic and IP anomalies have not been previously drilled. A diamond drill hole drilled on its northern margin off the IP anomaly (IE-DDH005-15) returned 291m @0.21g/t Au3 in altered volcanics and porphyritic quartz microdiorites. One RC hole from 2002 (YAR RC hole) was drilled towards the IP anomaly to a depth of 198m. The identity of this hole is uncertain in old databases, but little high-grade mineralisation was viewed in relevant assay files. Inspection of the drill platform during the IP survey revealed that the drill hole was collared in and drilled sub-parallel to a large (up to 40m wide) barren post-mineral dyke.

The source of the Northern Magnetic Anomaly (Figure 1) is interpreted from mapping and mineralogy as a deeply eroded porphyry system, and this is supported by its proximity to batholith rocks of the area. In contrast, the Southern Magnetic Anomaly is more distal from the Cretaceous coastal batholith and is associated with rocks of a more porphyritic nature of probable Cretaceous age, intruding older rocks such as the Jurassic Chocolate Formation which are potential mineralisation hosts. The Southern Magnetic Anomaly area is considered to hold considerably more potential to conserve uneroded porphyry-style mineralisation.

Mapping and selected rock geochemistry has shown that the high chargeability anomaly is principally located in steeply southerly dipping porphyritic quartz microdiorites of probable Cretaceous age with strong zones of potassic alteration. At surface the IP anomaly itself is partially covered by an andesite with lesser geochemical response. Copper oxides are commonly present in the form of malachite (see Figure 6). This rock intrudes into altered Jurassic volcanics of the Chocolate Formation. Structures parallel to the regional cross- Andean Chololo structure, which occurs south of the anomaly, control the limits of the Southern Magnetic Anomaly and the high chargeability anomaly. Downthrow is to the south-east and a further exploration target exists in downthrown blocks adjacent to the Chololo fault. Several Andean strike structures, apparently post-mineralisation, cross the anomalies. Some are occupied by post-mineral dykes such as that encountered in the YAR RC hole shown in Figure 4. The high degree of faulting gives the area a generally low resistivity as evidenced by the IP survey (see Figure 5).

³ Erratum. Drill hole ID: IE-DDH-005-15 was first reported in the Company's IPO prospectus dated 3^rd December 2021. The Company wishes to advise that the hole reported an intercept of 213 metres at 0.13% Cu. The Company wishes to advise the market that this non-material intercept was incorrectly reported, and should have been reported as 291 metres at 0.21 g/t Au from 102 metres.

⁴ The presence of copper oxides in hand specimen 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.

Next Steps

The combination of exploration methods has produced geologically well-supported drill targets over a strike-length of >1km in an area that is previously undrilled. The area is considered highly prospective to host porphyry copper style mineralisation due to the known occurrence of this style of mineralisation on the property, the favourable geology, and robust geophysical anomalies. Drill permitting for a semi-detailed EIA is being initiated and typically takes up to 12 months to final approval and drilling.

APPENDIX 3

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. 2023 rock geochemical sampling at Ilo Este was done on a 200 x 100m grid or where access roads exposed suitable faces for sampling. A total of 154 rock samples were collected. At each site, 12 to 15 subsamples of up to 0.3kg each were taken and split to a single composite of approximately 2.5kg. The composite was analysed using ICP methods at accredited laboratories in Peru. 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.

 

Criteria	JORC Code explanation	Commentary
		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.
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.	RC sample recovery was assessed visually and from sample weights recorded at the laboratory. Core barrel length and core length measurements were made so that core recoveries could be estimated. Recoveries were good and no significant core loss was experienced.
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.	The RC drill holes completed by Peruvian Latin Resources were qualitatively logged for lithology, alteration, and mineralisation. All diamond drill core was qualitatively logged for lithology, alteration and mineralisation which has been inspected qualitatively. No geotechnical logging was performed. Photographs were taken of all the core in sample boxes.
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.	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 Representatively 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).

 

Criteria	JORC Code explanation	Commentary
	Whether sample sizes are appropriate to the grain size of the material being sampled.	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. 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.	RC samples were assayed for 22 elements using an X-ray florescence assay technique (ME-XRF). Gold was assayed in diamond drill holes using a 30g fire assay, which is considered a total assay technique. Copper and 35 other elements were assayed in diamond drill holes using ICP- AES following a 4-acid digest and is considered total for Cu and Zn. This method is considered suitable for Cu and other base metals considering the matrix minerals present in the deposit. Analytical techniques and procedures are appropriate for the style of mineralisation. Blanks and field duplicates were inserted at a rate of approximately 1 in 40 samples each and certified reference standards were inserted approximately 1 in 20. Laboratory duplicates were also undertaken approximately 1 in 40 samples.
		Mobile Drone-mounted magnetometer with fixed base station magnetometer. Altitude of drone approximately 30m and ground speed 10m/second. 25 readings per second in continuous mode. Acquisition geographic datum: WGS84/19SStandard acquisition time zone: GMT IGRF (International Geomagnetic Reference Field) for May 2023 Ilo Norte project: Magnetic Field Intensity 23,147.8 nT Inclination -12.5 deg Declination -6.2 deg. 29 lines of total length 150km were flown in a direction N90E. 9 N-S tie lines were flown. Diurnal variations were checked from the Base Station magnetometer and despiking carried out before processing of total magnetic field data. Minimal solar activity was noted during the survey
		Logistics and data acquisition were carried out by contractors under direct supervision of Solis. After despiking and altitude and flight direction adjustments, of the 4,517,789 readings taken, 22,024 (0.49%) were rejected for QAQC reasons by the contractor. Processing was carried out by the contractor using 3D inversion modelling to identify subsurface magnetic susceptibility. Maps were produced in WGS84/19S datum for total magnetic field, analytic signal, reduction to pole, and first vertical magnetic derivative.

 

Criteria	JORC Code explanation	Commentary
		At Ilo Este an IP survey of total line length 10.5km was conducted in September 2023 by Real Eagle Explorations EIRL of Lima. A 10 channel Iris Elrec-Pro Receptor and an Innova Electronics (5000W/3000V) transmitter were used. Acquisition mode used was a pole-dipole configuration with a dipole separation of 100m to a nominal depth of 500m.
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.	There has been no verification of significant intersections by either independent or alternative company personnel. There have been no twin drill holes completed. There have been no adjustments made to the assay data. Sample data recorded in the field was entered into Excel spreadsheets and verified and cross checked against assay reports from the laboratory. Logging data was entered into Excel spreadsheets and subsequently cross checked against hand drawn summary logs. All data is stored electronically in a company server-based file system with regular offsite back-ups.
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.	Drill holes completed by Peruvian Latin Resources had collar surveys completed using a hand help GPS unit. Down hole surveys were not undertaken. The diamond drill holes completed by Compañía Minera Zahena S.A.C. had drill hole collars surveyed with a handheld GARMIN GPS (Model GPSMAP 64s) and downhole surveys completed every 50- 100 m with a Ranger Survey Systems FlexIT survey tool. Data has been collected in UTM zone 19S coordinates. The Ilo topography is a 1:5,000 scale Digital Terrain Model generated from digital restitution of ortho-rectified 1:20,000 scale aerial photography and associated ground controls. The accuracy is considered adequate for the current early phase of exploration at each project.
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.	Historical drilling at both deposits has been completed on an irregular grid and at varying orientations. Given the mineralisation is structurally controlled and/or discreet this drill spacing is too wide to interpret continuity between drill holes. Sample compositing has not been applied.

 

 

Criteria	JORC Code explanation	Commentary
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.	Due to the wide spaced drilling and variable nature of the mineralisation at each deposit the relationship between the sample length and the true thicknesses of the mineralisation is currently unknown.
Sample security	The measures taken to ensure sample security.	Company representatives completed the despatch and transport of samples to Lima in numbered and locked containers. At no time were the samples accessed by third party personnel. Diamond drill core is stored in a warehouse at the llo East project. Coarse rejects and sample pulps were initially stored at the SGS Laboratory warehouse before being returned to Peruvian Latin Resources.
Audits or reviews	The results of any audits or reviews of sampling techniques and data.	There have been no detailed audits or reviews of the historical or recent sampling techniques. Solis has conducted an internal technical review of the historical Ilo Project data.
Other Substantive Data	Other exploration data	Results of magnetic inversion and ground induced polarisation survey please refer to body of text in this ASX release. Results of the rockchip geochemical survey are displayed in Figure 1 of this ASX release.

 

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.	Please see concession list in Appendix 1 of this ASX news release. All granted permits or applications are 100% held or initiated by Westminster Peru SAC - the Peruvian subsidiary of Solis Minerals. The Ilo Este Project area consists of 4 exploration licences of total area 3,200 Ha. A further application for one licence of 400 Ha has been submitted. The Ilo Norte Project Area consists of 8 exploration licences of total area 7,700 Ha. The Cinto Project Area consists of 6 exploration licences of total area 2,700 Ha. Further applications for two licences of total area 500 Ha have been submitted. The Regional Exploration Project Area consists of 13 exploration licences of total area 11.500 Ha. Further applications for 12 licences of total area 10,100 Ha have been submitted. Licences are in good standing and have no known environmental or other liabilities of any kind.
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties.	A complete technical description of previous exploration is available in Section 8 of the Solis Minerals Prospectus published on 10th November 2021. Table 1 of this ASX release provides a summary of the exploration activities.
Geology	Deposit type, geological setting and style of mineralisation.	A complete geological description is available in Section 8 of the Solis Minerals Prospectus published on 10th November 2021. Mineralisation at Ilo Este is interpreted to be a Cu-Au porphyry system due to characteristic alteration and mineralisation suites. A Northern Belt (containing the Northern Magnetic Anomaly) is thought to be deeply eroded. A Southern Belt (containing the Southern Magnetic Anomaly) shows evidence of lesser erosion and potential to host more mineralisation than the Northern Belt. Oxide zone - copper oxides (principally malachite) occur sporadically across the Northern and Southern Belts. Oxides are hosted by outcropping porphyritic quartz diorite and porphyritic granodiorite in the Northen Belt indicating deep erosion. In the Southern Belt a porphyritic quartz microdiorite, more distal from the granodiorite batholith, principally hosts oxides indicating lesser erosion. Sulphide zone - only encountered in the Northern Belt by diamond drilling. Copper sulphides (chalcopyrite-bornite) occur sporadically in stockwork veins and disseminations in porphyritic granodiorite and porphyritic quartz diorite.

 

		The main area of the Southern Belt has not been subject to any diamond drilling to date and no data on potential sulphide zones is available. Mineralisation at Ilo Norte is interpreted to be an IOCG type deposit contained within highly altered andesitic volcaniclastics of the Jurassic Chocolate Fornation. Contact metamorphism and metasomatism have produced at least 5 phases of widespread development of mostly lentiform mineral assemblages including copper, gold, silver, zinc, and minor cobalt.
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 complete description of drilling programs, assaying, and results is available in Section 8 of the Solis Minerals Prospectus published on 10th November 2021.

 

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.	N/A no new drilling data is included in this report.

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.	N/A no new drilling data is included in this report.
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
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.	A description of other exploration data up to 2021 is available in Section 8 of the Solis Minerals Prospectus published on 10th November 2021. Magnetic Vector Inversions were carried out on previous Teck datasets (2004) using modern software. This generated several magnetic anomalies which, after review and geological ranking, were staked by licence applications in the Regional Exploration program. A drone magnetometry survey of 150km line length was flown in 2023 over the southern part of Ilo Norte in an area known as Chancho al Palo. Four magnetic anomalies were identified for follow-up. Data related to the Ilo Este 2023 geochemistry, magnetic inversion, and Induced Polarisation survey are included in the text of this ASX 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.	Solis is initiating drill permitting at Ilo Este. Follow-up geophysical programs will follow at Ilo Norte (IP) to test for sulphides at depth at Chancho al Palo. Targeted drone magnetometry surveys will be carried out on prospective areas across all projects where warranted. Regional exploration consisting of mapping and geochemistry will be undertaken at priority areas in the Regional Exploration licences.
