SIGNIFICANT GOLD AND COPPER POTENTIAL AT OCEANIA PROJECT

Sankamap Metals Inc. has provided an exploration update from its 24,000-hectare Fauro property, located in the Shortland Islands, Western province, Solomon Islands.

Recent prospecting and geological mapping at the Meriguna target within the Fauro property were undertaken to validate historical sampling results and further refine target generation. Historical exploration at Meriguna includes drill intercepts of up to 35 metres grading 2.08 grams per tonne gold, trench results of eight metres at 27.95 g/t Au and rock samples returning values of up to 173 g/t Au. In addition, limited alluvial mining is currently being conducted by local landowners, providing further evidence of significant near-surface gold mineralization.

Chief executive officer John Florek commented: "Sankamap is actively advancing two significant mineralized systems within its 100-per-cent-owned Oceania project. Both the Kuma and Fauro projects demonstrate strong potential for significant gold and copper mineralization.

"At the Fauro property, multiple mineralized targets are situated along the rim of an ancient volcanic caldera, where sampling has returned exceptional gold and copper results. Recent work at the Kiovakase target has yielded high-grade gold values of up to 19.25 g/t Au, together with standout copper values reaching 4.09 per cent Cu (see press release dated July 16, 2025).

"Recent sampling at the Meriguna target, located approximately 2.5 km north of Kiovakase, has also identified strong mineralization comparable to that observed at Meriguna, further highlighting the scale and continuity of the mineralized system."

Highlights:

• Visible gold identified throughout the property in surface alluvial workings from local artisanal miners at the Meriguna prospect.
• Rock samples collected at Meriguna display similar alteration observed at the company's Kiovakase target located 2.5 kilometres to the south.
• Recent sampling at the Kiovakase target returned values of up to 19.25 g/t Au and 4.09 per cent Cu, representing the highest copper grades reported to date on the Fauro property and supporting potential for a porphyry system at depth.
• The continuing exploration program at the Fauro property is focused on expanding and refining historical mineralized zones to generate high-priority drill targets for 2026.

Discussion

The Fauro property is strategically situated along a regional copper-gold trend known for hosting major deposits, including Panguna and Lihir (see press release dated May 7, 2025). Fauro shares key tectonic and geological features with both Panguna and Lihir, and is situated in a largely underexplored region.

Lihir containing 71 million ounces gold (310 million tonnes containing 23 Moz Au at 2.3 g/t proven plus probable, 520 Mt containing 39 Moz Au at 2.3 g/t indicated, 81 Mt containing five Moz Au at 1.9 g/t measured and 61 Mt containing 4.9 Moz Au at 2.3 g/t inferred) and Panguna containing 19.3 Moz Au plus 5.3 Mt Cu (1.5 Mt containing 16.1 Moz Au at 0.33 g/t and 4.6 Mt Cu at 0.3 per cent indicated, and 300 Mt containing 3.2 Moz Au at 0.4 g/t and 0.7 Mt Cu inferred).

The initial phase of the exploration program at Fauro was strategically designed to validate historical surficial assay results, engage with local communities, and evaluate terrain and logistical conditions in preparation for a forthcoming drill campaign. As part of this effort, 15 preliminary grab samples were collected from the Meriguna target, one of three historically explored zones on the property.

The Meriguna target is underpinned by historically elevated trench, drill and grab sample grades. The area is also subject to active local alluvial mining, where gold is visually observable at surface through panning and sluicing, providing additional confirmation of significant near-surface mineralization.

Quality assurance and control procedures

Sample preparation and analysis was completed at the Brisbane, Australia, ALS Global facility accredited by the National Association of Testing Authorities and compliant with international standards ISO/IEC 17025. Samples were analyzed using four-acid digestion methods on 34 elements: HF-HNO3-HClO4 acid digestion, HCl leach and ACP-AES. Gold was analyzed using the fire assay technique with a 50-gram sample under the ALS code Au-AA26. A secure chain of custody procedure was maintained in storing and transporting samples. Sankamap uses industry standards for collecting samples taken on the Fauro property, and internal quality assurance and quality control procedures were followed by ALS.

Next steps at the Fauro property -- 2026 exploration

Historical drilling, surface sampling and geophysical work at the Fauro property have identified multiple near-surface epithermal gold systems with potential for an underlying porphyry system. Recent rock sampling at the Meriguna target is intended to confirm significant surface gold mineralization.

A phased exploration program is planned for 2026, beginning with continuation of systematic sampling to validate historical surface results. These data will guide follow-up geophysical surveys, if warranted, targeting signatures characteristic of porphyry and epithermal systems.

Results will be integrated with existing data sets to design a focused drill program aimed at confirming historical intersections and testing extensions of mineralization that remain open at depth and along strike.

About Sankamap Metals Inc.

Sankamap is a Canadian mineral exploration company dedicated to the discovery and development of high-grade copper and gold deposits through its flagship Oceania project, located in the South Pacific. The company's fully permitted assets are strategically positioned in the Solomon Islands, along a prolific geological trend that hosts major copper-gold deposits, including Newmont's Lihir mine, with a resource of 71.9 million ounces of gold (310 Mt containing 23 Moz Au at 2.3 g/t proven plus probable, 520 Mt containing 39 Moz Au at 2.3 g/t indicated, 81 Mt containing five Moz Au at 1.9 g/t measured and 61 Mt containing 4.9 Moz Au at 2.3 g/t inferred).

Exploration is actively advancing at both the Kuma and Fauro properties, part of Sankamap's Oceania project in the Solomon Islands. Historical work has already highlighted the mineral potential of both sites, which lie along a highly prospective copper and gold-bearing trend, suggesting the possibility of further, yet-to-be-discovered deposits.

At Kuma, the property is believed to host an underexplored and largely untested porphyry copper-gold system. Historical rock chip sampling has returned consistently elevated gold values above 0.5 g/t Au, including a standout sample assaying 11.7 per cent Cu and 13.5 g/t Au, underscoring the area's significant potential.

At Fauro, particularly at the Meriguna target, historical trenching has returned highly encouraging results, including 8.0 metres at 27.95 g/t Au and 14.0 metres at 8.94 g/t Au. Complementing these results are exceptional grab sample assays, including historical values of up to 173 g/t Au, along with recent sampling by Sankamap at the Kiovakase target, which returned numerous high-grade copper values, reaching up to 4.09 per cent Cu. In addition, limited historical shallow drilling intersected 35.0 metres at 2.08 g/t Au, further underscoring the property's strong mineral potential and the merit for continued exploration. With a commitment to systematic exploration and a team of experienced professionals, Sankamap aims to unlock the untapped potential of underexplored regions and create substantial value for its shareholders.
