SANKAMAP ADVANCES TOWARD INAUGURAL DRILLING AT KUMA PROPERTY IN THE SOLOMON ISLANDS

Sankamap Metals Inc. has provided an exploration update from its 4,500-hectare Kuma property, located approximately 37 kilometres southeast of Honiara in south-central Guadalcanal, Solomon Islands.

In preparation for its inaugural drill program, the company has mobilized a field crew to advance camp construction, complete drill pad development and conduct rock sampling, while integrating existing data to refine and prioritize high-potential targets.

The Kuma property is strategically located along a highly prospective trend that hosts several major deposits, including Lihir (1) and Panguna (2), both sharing geological similarities to the Kuma property.

(1) Lihir containing 71 million ounces (oz) gold (Au) (310 million tonnes (t) containing 23 million oz Au at 2.3 grams per tonne (g/t) proven plus probable (P&P), 520 million t containing 39 million oz Au at 2.3 g/t indicated, 81 million t containing five million oz Au at 1.9 g/t measured, 61 million t containing 4.9 million oz Au at 2.3 g/i inferred).

(2) Panguna containing 19.3 million oz Au plus 5.3 million t copper (Cu) (1.5 million t containing 16.1 million oz Au at 0.33 g/t and 4.6 million t Cu at 0.3 per cent indicated, 300 million t containing 3.2 million oz Au at 0.4 g/t and 700,000 t Cu inferred).

Chief executive officer John Florek commented:

"We are excited to launch our inaugural drill program at Kuma. With ongoing fieldwork, including camp and drill pad development, rock sampling, and a drill rig on route to the property, we are well positioned to advance high-potential targets. The team is focused on efficiently progressing the program in this highly prospective region, with drilling on track to begin in February, 2026.

"Kuma benefits from established in-country support, located approximately 15 kilometres south of the producing Gold Ridge mine (3). Compelling historical and recent exploration results indicate the presence of a significant mineralized system, interpreted to be analogous to porphyry-style copper-gold systems. Notably, historical boulder sampling has returned values of up to 13.5 g/t Au and 11.7 per cent Cu, underscoring the exceptional exploration potential."

(3) Goldridge containing 8.4 million oz Au (23 million t containing 860,000 oz Au at 1.15 g/t measured, 79 million t containing 3.1 million oz Au at 1.2 g/t indicated, 89 million t containing 3.3 million oz Au at 1.14 g/t inferred (191 million t containing 7.2 million oz Au at 1.17 g/t), 13.4 million t containing 590,000 oz Au at 1.28 g/t proven, 14.3 million t containing 600,000 oz Au at 1.30 probable (P&P 27.7 million t containing 1.2 million oz Au at 1.29 g/t)).

Highlights:

• Drill pad construction at Kuma completed to support the upcoming program;
• Field crew mobilized to advance camp construction and rock sampling;
• Reconnaissance sampling near the drill pad continuing to refine target confidence;
• Additional downstream sampling conducted to expand the target area;
• Drill rig dispatched to Guadalcanal to begin operations;
• Exploration program focused on discovering new mineralization and prioritizing future drill targets based on alteration, copper and gold geochemical anomalies, and coincident geophysical responses;
• Timing remains on track to commence drilling at Kuma in February, 2026.

Field program update -- Kuma property

Field activities at the Kuma property are focused on preparing for the planned inaugural drill program, including pad and camp construction, as well as prospecting and sampling. Initial drill pad construction has been completed, establishing the groundwork for safe and efficient drilling operations. Camp construction is under way and expected to be completed in the coming weeks.

The company has completed an initial phase of surface rock sampling, with 44 samples collected and shipped to Australia for geochemical analysis and hyperspectral characterization. Sampling was conducted to complement historical data sets, refine the geological understanding and support continuing drill targeting. Additional surface rock sampling is planned across other prospective areas of the property, including near numerous additional geophysical anomalies, as field activities continue.

Encouraging cross-cutting relationships observed in the field indicate multiple phases of veining and mineralization, consistent with a long-lived hydrothermal system. Recent sampling highlights early-stage stockwork quartz veining that is overprinted by later, cross-cutting quartz-sulphide veins containing abundant pyrite.

Quality assurance and control procedures

Sample preparation and analysis were completed at the ALS Global facility in Brisbane, Australia, which is accredited by the National Association of Testing Authorities (NATA) and compliant with international standard ISO/IEC 17025. Samples were analyzed using four-acid digestion methods on 34 elements, including HF-HNO3-HClO4 digestion, HCl leach and ICP-AES (inductively coupled plasma atomic emission spectroscopy). Gold was analyzed by fire assay using a 50-gram sample under ALS analytical code Au-AA26. Hyperspectral analysis was conducted on all samples using ALS analytical code TRSPEC-20, which uses a TerraSpec 4 HR spectrometer. A secure chain-of-custody procedure was maintained during sample storage and transportation. Sankamap uses industry standards for collecting samples taken on the Kuma property, internal quality assurance and quality control (QA/QC) procedures were followed by ALS.

About Sankamap Metals Inc.

Sankamap Metals 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.

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 (Cu-Au) 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.
