Highlights

• Solis signs binding agreement effective May 29, 2023 to acquire the "Jaguar" project in Bahia state, north-east Brazil

• Jaguar pegmatite has confirmed Spodumene grades in oxidised pegmatite up to 4.95% Li2O from rock chip samples

• Extensive pegmatite body mapped over 1km of strike, with widths in excess of 50m with coarse visible Spodumene exposed across pegmatite body

• Solis' largest shareholder, Latin Resources, to provide exploration guidance and country experience

• The Jaguar pegmatite is located proximal to a large granitic source, and its geological setting is consistent with other hard rock lithium provinces in Brazil

• Jaguar project is located on a granted mining lease with permits in place to commence drilling. Solis has secured a drill rig and plans to initiate drilling in June

Vancouver, British Columbia--(Newsfile Corp. - May 31, 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 its entry into a binding option agreement to purchase the "Jaguar" hard rock Lithium project in Bahia State Brazil.

Executive Director Matthew Boyes quoted:

"Brazil is fast becoming a significant player in the hard rock Lithium space. Solis's primary objective is to quickly position itself by acquiring highly prospective underexplored projects in the northeast of Brazil. The Jaguar pegmatite hosts confirm LCT-bearing pegmatites with some of the coarsest and most abundant Spodumene occurrences I have seen. These tenements in what may be a new Lithium province are a fantastic addition to our already large tenement position in the northeast of Brazil, and with drilling to commence immediately, I am excited by this opportunity to better understand the potential of this very exciting system."

Sampling and Li2O grade confirmation

A series of surface samples were collected from the exposed portion of the Jaguar pegmatite within an artisanal open pit or "Garimpo" located at the Jaguar project (see Table 1 and Figures 1 & 2). Samples were taken from the Spodumene-rich pegmatite quartz core primarily to confirm the grade of the visible Spodumene mineralisation. All samples were assayed at SGS GEOSOL Laboratories Ltda Brazil (see Appendix 2 for additional information on the quality of assay data and laboratory tests). A field campaign will commence in the coming weeks to complete systematic geochemical sampling of all the known outcrops plus mapping and target generation for follow-up drill programmes; Solis has secured a drill rig and plans to commence drilling in June.

Project Location

The tenements 871427/2006 and 873426/2021 are located in the province of Bahia in northeast Brazil. The tenements cover a combined area of 1,143Ha with mineral extraction rights granted for the extraction of dimension on the northernmost tenement. The Jaguar project is located 86km from Petrolina and Juazeiro, two major regional cities on the San Francisco River, which forms the border between Pernambuco and Bahia states. Road access is via a paved highway and 4km of unsealed track to the project. Hydro-generated power is distributed along the main highway and located within 4.5km of the northern 871427 tenement. Land use is restricted to goat pasture and vegetation and is typical of a semi-arid tropical environment.

APPENDIX 2

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 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.	Sampling was predominantly cut channels and rock chips. Sampling was focused on confirmation of mineralisation of Lithium from selected mineral species in the case of Jaguar "Weathered Spodumene". Samples are not to considered representative of exposed widths of the pegmatite body, samples were not collected over standard widths or perpendicular to orebody orientations. Samples size ranged between 1.5-3kg and industry standard an acceptable weight to ascertain a representative sample for preparation and assay.
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.	Solis Minerals geologists logged all sample noting mineralogy, lithology, alteration and weathering sate of samples obtained. Logging is both quantitative and qualitative in nature. All samples including any submitted CRM material are individually photographed before submission.
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.	Samples were taken to check the grades of exposed spodumene mineralisation, no systematic sampling across known exposed pegmatites was completed, samples were rock chips only and no systematic channel sampling completed to date. Duplicate samples were taken and stored for future reference. Samples are considered to be representative of exposed Spodumene crystals within Jaguar open pit and of appropriate size with respect to sampled material.
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 samples were assayed at SGS GEOSOL Laboratories Ltda Brazil. Analysis procedures are considered to be appropriate for Lithium and multielement analysis. Rock chips and grab samples are assayed via ICM90A (fusion by sodium peroxide and finish with ICP-MS/ICP-OES) for a 56-element suite at the SGS Geosol Laboratorios located at Vespasiano/Minas Gerais, Brazil. If lithium results are above 15,000ppm, the Lab analyze the pulp samples just for lithium through ICP90Q (fusion by sodium peroxide and finish with ICP/OES). Solis inserted industry standard OREAS CRM for analysis, standards utilised were OREAS 750 and OREAS 22h, reported values are within 1SD of CRM certified values.
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 Minerals data is verified by the Competent person. All data is stored in an electronic Access Database. Assay data and results is reported, unadjusted. Li2O results used in the market are converted from Li results multiplying it by the industry factor 2.153.
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. All samples were captured using a handheld GPS.
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 die 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.	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 Jaguar Project area consists of 2 exploration licences held in the name of Marica Mineração Ltda, and Ingramar Ltda. Onca Mineracao has signed a binding option agreement sheet with both companies giving Onca the right to purchase 100% of both licences "see section terms of agreement" in release. Exploration Licences: 871427/2006, 872376/2021. Licences are in good standing and have no known environmental or liabilities of any kind.
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) located close to the large Granitoids from the G3 suite with batholiths, stocks and dykes represented. Pegmatites are located within 0-5km of the granite contacts.
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 including all known outcropping pegmatites. Solis has signed a diamond drill contract for 2500m of HQ diameter drill core to be performed on existing targets and below the known outcropping mineralisation at the Jaguar project. It is premature to provide diagrams of possible extensions.
