Solis Minerals Ltd.: Solis Announces 22 Lithium Exploration Licences Acquired in Brazil

• Solis Minerals has acquired 22 exploration licences covering a total area of 248 km² (24,800 hectares) in northeastern Brazil.
• The regional structural geological setting is similar to Latin Resources' Colina deposit with large granitic intrusives located proximal to meta sedimentary-volcanic sequences.
• Borborema project areas are greenfield sites and have seen limited to no systematic exploration for Lithium-Cesium-Tantalum (LCT) bearing pegmatites.
• Team to be deployed to commence reconnaissance and field mapping to design initial geochemical sampling programmes and target generation.
• The Company continues to identify and evaluate exploration opportunities, primarily in the battery metals space in South America.
• Well funded with approximately A$2.1 million cash to undertake first-pass exploration efforts at these new lithium opportunities.

Vancouver, British Columbia--(Newsfile Corp. - February 15, 2023) - Solis Minerals Ltd. (ASX: SLM) (TSXV: SLMN) (OTCQB: SLMFF) (FSE: 08W) ("Solis Minerals" or "the Company") is pleased to provide shareholders with an update on acquiring 22 exploration licence application areas in northeast Brazil ("Borborema Project"). The licences acquired are located within the states of "Rio Grande Do Norte" and "Paraiba" close to major regional centres such as Natal and Recife, both well-serviced and boasting good infrastructure and services.

CEO Jason Cubitt commented:

"Brazil is fast becoming a Tier 1 destination for hard rock lithium explorers and producers alike. The value to be generated is significant in the short term through building an extensive portfolio of prospective lithium ground in the country to complement our copper exploration assets in Peru. Brazil is still very much in its infancy with lithium exploration and offers a junior explorer such as Solis an exceptional opportunity to discover a material asset. Having our largest shareholder, Latin Resources, in the country will expedite the commencement of exploration and building of the team needed to advance these projects. I am excited to see our team commence first-pass reconnaissance and mapping programmes over the coming months."

Brazil Lithium Projects

Borborema Project

The Company has now secured the acquisition of 22 licence areas in the northeast of Brazil, with settlement expected to occur within 30 days. The tenements cover a total area of 24,800 hectares in predominantly greenfield terrain. The tenements have yet to be exposed to systematic modern exploration techniques targeting LCT-bearing pegmatite systems. Historically the Borborema pegmatitic province has been reported to host several mineralised pegmatite occurrences and artisanal works producing Be, Nb-Ta, Li, Sn, gems, quartz, feldspar and others. Historical mining in the region, and the presence of the Niobium-Tantalum, Lithium and feldspars, indicate the area is endowed with LCT-bearing pegmatite systems.

The most prospective potential host units for the mineralised pegmatites are similar to the suite hosting the Colina-Salinas pegmatites held by Latin Resources Limited in the state of Minas Gerais. They consist predominantly of metavolcanic and metasedimentary rocks (schist, gneiss and quartzites) from the Serido Formation, located close to the large granitoids from the G3 suite (pink/red in Figure 1) with batholiths, stocks and dykes represented. The G3 suite is the main intrusive system in the province and potentially the source of any emplaced pegmatite bodies. The licence areas acquired have been systematically selected to be close to, or straddle, the contact zone between these granitic intrusives and surrounding metavolcanic sequences and the zone referred to as the "Goldilocks Zone" in exploration for LCT-bearing systems.

The Company has completed the initial compilation of available historical geological data and will now follow up with a comprehensive field programme specifically aimed at generating near-term drill targets. The Company has recently expanded the team by adding a Senior Project Geologist in Brazil who is currently undergoing onsite training at Latin Resources' Salinas Lithium Project in Minas Gerais. Once completed in mid-February and subject to the final access agreement, the team will be mobilised to commence systematic regional mapping and soil and rock chip geochemical sampling to generate drill targets and identify the most prospective terrain within the licence areas.

APPENDIX 2

JORC Code, 2012 Edition - Table 1

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections)

Criteria	JORC Code explanation	Commentary
Sampling techniques	Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where 'industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.	N/A No sampling has been undertaken by Solis Minerals.
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).	N/A - No drilling has been undertaken.
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.	N/A - No drilling has been undertaken.
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.	N/A - No drilling has been undertaken.
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. Whether sample sizes are appropriate to the grain size of the material being sampled.	N/A - No drilling has been undertaken.
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.	N/A - No assay results are being reported.
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.	N/A - No assay results are being reported.
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.	Data is shown using the UTM SIRGAS 2000 zone 23 South grid system.
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.	N/A - No drilling has been undertaken.
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.	N/A - No drilling has been undertaken.'
Sample security	The measures taken to ensure sample security.	N/A - No drilling has been undertaken.
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 Minerals 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.	The Borborema Project area consists of 22 exploration licences held in the name of Onça Mineração Ltda, which is to become a wholly owned subsidiary of Solis Minerals Limited on settlement of the proposed acquisition. Exploration Licences: 846.232/2022, 846.233/2022, 846.234/2022, 848.411/2022, 848.412/2022, 848.413/2022, 848.414/2022, 848.415/2022, 848.416/2022, 848.417/2022, 848.418/2022, 848.419/2022, 848.420/2022, 848.423/2022, 848.424/2022, 848.425/2022, 848.426/2022, 848.427/2022, 848.428/2022, 848.429/2022, 848.430/2022, 848.431/2022 are 100% fully owned by Onça Mineração Ltda. Licences have been granted and now will pass to the ANM (Brazilian Mining Agency) for manual review and validation before final publication in the Governments official Gazette.
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties..	N/A - the Company is not aware of any previous exploration being undertaken within the tenements.
Geology	Deposit type, geological setting and style of mineralisation.	Prospective potential host units for the mineralised pegmatites are similar to the suite hosting the Colina-Salinas pegmatites held by Latin Resources Limited (ASX:LRS) in the state of Minas Gerais. They consist predominantly of metavolcanic and metasedimentary rocks (schist, gneiss and quartzites) from the Serido formation, located close to the large Granitoids from the G3 suite with batholiths, stocks and dykes represented.
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.	N/A no new drilling data is included in this report.
Data aggregation methods	In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated.	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.	The Company has included various maps and figures showing the sample results and geological context.
Balanced reporting	Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced avoiding misleading reporting of Exploration Results.	N/A no new results are included in this report.
Other substantive exploration data	Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	N/A no new results are included in this report.
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 Minerals will undertake extensive validation field confirmation and sampling of the regional geological setting of various target areas identified from the historical data and recent remote sensing over the Borborema Project area. It is premature to provide diagrams of possible extensions.
