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
Highlights of the 2025 Exploration Program:
• New discovery of polymetallic mineralization at the Mossikro Prospect located 10
kilometers to the south-southwest of the existing Samapleu and Grata Deposits.
• Significant new polymetallic mineralization also identified to the southwest of the
Samapleu Extension Deposit within the 2024 Preliminary Economic Assessment area but
outside of the current Mineral Resource Estimate.
• New mineralized discoveries demonstrate the potential for expansion of the existing
Mineral Resource as well as the regional scale potential of the Project.
Montreal, Quebec – September 9, 2025 – Sama Resources Inc. (“Sama” or the “Company”) (TSXV:
SME) (OTC: SAMMF) together with its joint venture partner Ivanhoe Electric Inc. (“Ivanhoe Electric”)
(NYSE American: IE; TSX: IE), is pleased to provide an update on the 2025 exploration program at the
polymetallic Samapleu-Grata Nickel-Copper Project (the “Project”) in Côte d'Ivoire, West Africa, which
includes the polymetallic Samapleu and Grata Deposits which were the focus of the 2024 Preliminary
Economic Assessment (the “2024 PEA Area”) (refer to Sama’s March 21, 2024 news release). The Project
is a 60/40 joint venture between Ivanhoe Electric and Sama, with Sama acting as the operator (the “Joint
Venture”). In addition to a 60% interest at the Project level, Ivanhoe Electric also owns 22.7% of the
common shares of Sama.
The 2025 exploration program include s 4,500 meters (“m”) of diamond drilling as well as updated
environmental and social baseline studies to support Project advancement toward a mining permit
application (refer to Sama’s May 27, 2025 news release).
To date, approximately 840m of exploration drilling have been completed at the Mossikro Prospect 10
kilometers (“ km”) to the south- southwest of the existing mineral resources . Drilling has also been
conducted to the southwest of the Samapleu Extension Deposit.
Drilling has identified new polymetallic mineralization in both areas.
Dr. Marc-Antoine Audet, President and Chief Executive Officer of Sama Resources , commented, “The
discovery of Samapleu-like polymetallic mineralization at the Mossikro Prospect is further testament to
the regional prospectivity of the broader Samapleu-Grata Project. To date and since the initial Samapleu
Main discovery in 2010, across the 835 square kilometer license area, every regional electromagnetic
conductor that has been drilled has yielded the discovery of additional polymetallic mineralization, and
many remain untested. In addition, resource expansion drilling at the Samapleu Extension continues to
intersect thick intervals of polymetallic mineralization , with the potential to add additional resources
within the area of our 2024 Preliminary Economic Assessment . We plan to complete downhole
electromagnetic surveys in these areas to refine the extensions of the sulfide mineralization intersected
and support follow-up exploration drilling. Together with our partner Ivanhoe Electric, we are advancing
one of West Africa’s most promising polymetallic P rojects, while maintaining our strong commitment to
environmental stewardship and community development.”
Discovery of new polymetallic mineralization at the Mossikro Prospect , characterized by a similar
geophysical signature as the Samapleu and Grata Deposits, mineralization style, and host rock geology, is
validation of the regional exploration model, and reaffirms the district-scale potential of the Project. Since
Sama commenced exploration activities in 20 10 and discovered the Samapleu Main and Extension
Deposits, regional exploration targeting electromagnetic conductors has so far yielded mineralized zones
at Grata (on which a mineral resource was subsequently declared), and at the Yepleu and Bounta prospects.
The discovery at Mossikro adds to these successes, with further anomalies yet to be evaluated (Figure 1).

program, and other regional targets and prospects.
New Massive and Semi-Massive Sulfide Mineralization Discovered at the Mossikro Prospect
At the Mossikro Prospect, two drill holes totaling 536m were completed over approximately 200m of the
prospective strike length of the regional 4km by 1.5km conductive anomaly detected in the 2013 airborne
geophysical survey. Drilling intersected polymetallic mineralization in both holes, characterized by semi-
massive to massive sulfide mineralizatio n hosted in a nar row interval of the prospective ultramafic
intrusive. Downhole time-domain electromagnetic surveying will be used to detect potential expansions
and thicker accumulations of mineralization.
At a 0.10% nickel (“Ni”) cut-off grade, comparable to the $16.34 per tonne net-smelter return cut-off used
for the Samapleu and Grata Mineral Resource Estimate, highlights from the Mossikro Prospect include
(Table 1):
• S-354: 5.62m grading 0.67% Copper (“Cu”) Eq1 from 167.28m depth
• S-355: 5.90m grading 0.29% CuEq from 184.25m depth
o including 1.25m grading 0.80% CuEq starting at 184.25m depth
Resource Expansion Drilling at the Samapleu Extension Deposit Provides the Opportunity to
Grow the Existing Samapleu Mineral Resource
Resource expansion drilling at the polymetallic Samapleu Extension Deposit was designed to step out
from the Samapleu Mineral Resource Estimate and explore an area where past drilling in 2022 intersected
high-grade, copper-rich, and polymetallic mineralization. Hole S-353 totaling 303m, was completed at the
southwestern (“SW”) edge of the Samapleu Extension Deposit, successfully expanding mineralization
laterally to the SW and vertically. Mineralization at the SW edge of the Samapleu Extension Deposit
demonstrates the growth potential of Mineral Resources within the 2024 P EA Area. Downhole time -
domain electromagnetic surveying will be used to support further resource expansion drilling.
At a 0.10% Ni cut-off grade, comparable to the $16.34 per tonne net-smelter return cut-off used for the
Samapleu and Grata Mineral Resource Estimate, highlights from Samapleu Extension include (Table 1):
• S-353: 99.55m grading 0.48% CuEq from 15.55m depth
o including 7.15m grading 1.27% CuEq from 20.80m depth
• and 5.30m grading 0.62% CuEq from 181.70m depth
o including 0.30m grading 2.69% CuEq from 14.50 m depth
• and 81.20m grading 0.57% CuEq from 191.5m depth
o including 18.85m grading 0.76% CuEq from 227.00m depth
o and including 0.40m grading 3.96% CuEq from 259.00m depth
The 2025 Exploration Program still has 3,000m of Further Drilling to be Completed
A 3,000m infill drilling program is scheduled to begin this fall at the Grata Deposit which is designed to
upgrade Inferred Resources to Indicated Resources, improving the confidence of Mineral Resource for
future economic and engineering studies . The Grata D eposit accounts for nearly 70% of the Inferred
Resources used in the 2024 P reliminary Economic Assessment, comprising 67.3 million tonnes grading
0.24% Ni, 0.25% Cu, 0.01% cobalt (“Co”), 0.26 grams per tonne (“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 Permitting are Ongoing
The 2025 exploration program also included further environmental and social studies within the 2024
PEA Area to update previous studies completed at the Samapleu Deposit and collect baseline data for the
Grata Deposit. Fieldwork, including wildlife and vegetation inventory, water sampling, was completed by
SIMPAE. The program was completed to current national and international permitting standards to
support the Project’s permitting and future development.
