The 2025 Exploration Program at the Samapleu-Grata Nickel-Copper Project Identifies New Polymetallic Mineralization 10 kilometers to the South-Southwest of the Existing Mineral Resources

(TheNewswire)

Highlights of the 2025 Exploration Program:

• New discovery of polymetallic mineralization at theMossikro Prospect located 10 kilometers to the south-southwest of theexisting Samapleu and Grata Deposits.

• Significant new polymetallic mineralization alsoidentified to the southwest of the Samapleu Extension Deposit withinthe 2024 Preliminary Economic Assessment area but outside of thecurrent Mineral Resource Estimate.

• New mineralized discoveries demonstrate the potentialfor expansion of the existing Mineral Resource as well as the regionalscale potential of the Project.

Montreal, Quebec – TheNewswire- September 9, 2025 – Sama ResourcesInc. (“ Sama ” or the “ Company ”) (TSXV: SME) (OTC: SAMMF) together with its joint venturepartner Ivanhoe Electric Inc. (“Ivanhoe Electric”) (NYSE American:IE; TSX: IE), is pleased to provide an update on the 2025 explorationprogram at the polymetallic Samapleu-Grata Nickel-Copper Project (the“Project”) in Côte d'Ivoire, West Africa, which includes thepolymetallic Samapleu and Grata Deposits which were the focus of the2024 Preliminary Economic Assessment (the “2024 PEA Area”) (referto Sama’s March 21, 2024news release ). The Project is a 60/40joint venture between Ivanhoe Electric and Sama, with Sama acting asthe operator (the “Joint Venture”). In addition to a 60% interestat the Project level, Ivanhoe Electric also owns 22.7% of the commonshares of Sama.

The 2025 exploration program includes 4,500 meters(“m”) of diamond drilling as well as updated environmental andsocial baseline studies to support Project advancement toward a miningpermit application (refer to Sama’s May 27, 2025news release ).

To date, approximately 840m of exploration drillinghave been completed at the Mossikro Prospect 10 kilometers (“km”)to the south-southwest of the existing mineral resources. Drilling hasalso been conducted to the southwest of the Samapleu ExtensionDeposit.

Drilling has identified new polymetallic mineralizationin both areas.

Dr. Marc-Antoine Audet, President and Chief ExecutiveOfficer of Sama Resources, commented, “ The discoveryof Samapleu-like polymetallic mineralization at the Mossikro Prospectis further testament to the regional prospectivity of the broaderSamapleu-Grata Project. To date and since the initial Samapleu Maindiscovery in 2010, across the 835 square kilometer license area, everyregional electromagnetic conductor that has been drilled has yieldedthe discovery of additional polymetallic mineralization, and manyremain untested. In addition, resource expansion drilling at theSamapleu Extension continues to intersect thick intervals ofpolymetallic mineralization, with the potential to add additionalresources within the area of our 2024 Preliminary Economic Assessment.We plan to complete downhole electromagnetic surveys in these areas torefine the extensions of the sulfide mineralization intersected andsupport follow-up exploration drilling. Together with our partner Ivanhoe Electric, we are advancingone of West Africa’s most promising polymetallic Projects, whilemaintaining our strong commitment to environmental stewardship andcommunity development. ”

Discovery of new polymetallic mineralization at theMossikro Prospect, characterized by a similar geophysical signature asthe Samapleu and Grata Deposits, mineralization style, and host rockgeology, is validation of the regionalexploration model, and reaffirms the district-scale potential of theProject. Since Sama commenced exploration activities in 2010 anddiscovered the Samapleu Main and Extension Deposits, regionalexploration targeting electromagnetic conductors has so far yieldedmineralized zones at Grata (on which a mineral resource wassubsequently declared), and at the Yepleu and Bounta prospects. Thediscovery at Mossikro adds to these successes, with further anomaliesyet to be evaluated (Figure 1).

New Massive and Semi-Massive Sulfide MineralizationDiscovered at the Mossikro Prospect

At the Mossikro Prospect, two drill holes totaling 536mwere completed over approximately 200m of the prospective strikelength of the regional 4km by 1.5km conductive anomaly detected in the2013 airborne geophysical survey. Drilling intersected polymetallicmineralization in both holes, characterized by semi-massive to massivesulfide mineralization hosted in a narrow interval of the prospectiveultramafic intrusive. Downhole time-domain electromagnetic surveyingwill be used to detect potential expansions and thicker accumulationsof mineralization.

At a 0.10% nickel (“Ni”) cut-off grade, comparableto the $16.34 per tonne net-smelter return cut-off used for theSamapleu and Grata Mineral Resource Estimate, highlights from theMossikro Prospect include (Table 1):

• S-354: 5.62m grading 0.67% Copper (“Cu”)Eq 1 from 167.28mdepth

• S-355: 5.90m grading 0.29% CuEq from 184.25mdepth

  • including 1.25m grading 0.80% CuEq starting at 184.25mdepth

Resource Expansion Drilling at the Samapleu ExtensionDeposit Provides the Opportunity to Grow the Existing Samapleu MineralResource

Resource expansion drilling at the polymetallicSamapleu Extension Deposit was designed to step out from the SamapleuMineral Resource Estimate and explore an area where past drilling in2022 intersected high-grade, copper-rich, and polymetallicmineralization. Hole S-353 totaling 303m, was completed at thesouthwestern (“SW”) edge of the Samapleu Extension Deposit,successfully expanding mineralization laterally to the SW andvertically. Mineralization at the SW edge of the Samapleu ExtensionDeposit demonstrates the growth potential of Mineral Resources withinthe 2024 PEA Area. Downhole time-domain electromagnetic surveying willbe used to support further resource expansion drilling.

At a 0.10% Ni cut-off grade, comparable to the $16.34per tonne net-smelter return cut-off used for the Samapleu and GrataMineral Resource Estimate, highlights from Samapleu Extension include(Table 1):

• S-353: 99.55m grading 0.48% CuEq from 15.55mdepth

  • including 7.15m grading 1.27% CuEq from 20.80mdepth

• and 5.30m grading 0.62% CuEq from 181.70mdepth

  • including 0.30m grading 2.69% CuEq from 14.50 mdepth

• and 81.20m grading 0.57% CuEq from 191.5mdepth

  • including 18.85m grading 0.76% CuEq from 227.00mdepth

  • and including 0.40m grading 3.96% CuEq from 259.00mdepth

The 2025 Exploration Program still has 3,000m ofFurther Drilling to be Completed

A 3,000m infill drilling program is scheduled to beginthis fall at the Grata Deposit which is designed to upgrade InferredResources to Indicated Resources, improving the confidence of MineralResource for future economic and engineering studies. The GrataDeposit accounts for nearly 70% of the Inferred Resources used in the2024 Preliminary Economic Assessment, comprising 67.3 million tonnesgrading 0.24% Ni, 0.25% Cu, 0.01% cobalt (“Co”), 0.26 grams pertonne (“g/t”) of palladium (“Pd”), 0.10 g/t of platinum(“Pt”), and 0.04 g/t of gold (“Au”).

Environmental Studies in Support of Future Permittingare Ongoing

The 2025 exploration program also included furtherenvironmental and social studies within the 2024 PEA Area to updateprevious studies completed at the Samapleu Deposit and collectbaseline data for the Grata Deposit. Fieldwork, including wildlife andvegetation inventory, water sampling, was completed by SIMPAE. Theprogram was completed to current national and international permittingstandards to support the Project’s permitting and futuredevelopment.
