Somerset Minerals Limited advised that results have now been received from the late-2025 regional geophysical and geochemical programs completed across its flagship Coppermine Project in Canada. The Company?s airborne gradiometer magnetic survey and first-pass glacial till geochemical survey have successfully delivered Somerset?s key objective, serving to identifying multiple new undercover exploration targets where strong copper anomalies coincide with demagnetised magnetic features, interpreted as altered (and potentially mineralised) fault corridors. The standout result is the newly defined Talisker Corridor, now ranked as Somerset?s highest-priority regional target.

Talisker comprises a highly anomalous and very strong ~17 km-long coincident geochemical and geophysical anomaly, which contains 4 of the 10 samples that contained >1,000 ppm Cu from the survey, and a peak value of 3,790 ppm Cu (0.38% Cu) in till, an exceptional outcome for a first-pass, district-scale survey. Talisker is located just ~5 km from White Cliff Minerals? Danvers deposit and is interpreted to connect to the same fault that hosts the Danvers deposit (the Teshierpi Fault), which significantly increases the prospectivity of the corridor and its likelihood to also contain high-grade copper mineralisation.

The strongest responses are developed in areas with little to no outcrop and minimal historical exploration, supporting Somerset?s view that sizeable copper systems likely remain concealed beneath a thin (1?10 m) veneer of cover, which shields much of the landholding. Somerset has appointed a geophysical contractor to undertake several IP surveys, including at Talisker, which is scheduled to begin in early-March. At Jura, Somerset has appointed a diamond drilling contractor for a ~3,000 m diamond drilling program, with mobilisation targeted for late February, to accelerate follow-up drilling at Jura North.

The program is designed to materially grow the Jura North discovery by testing mineralisation along strike and down dip, while also assessing potential parallel lodes highlighted by the recent IP?resistivity survey. Somerset Minerals has completed a major district-scale targeting program across the Coppermine Project, designed to identify coincident geochemical and geophysical anomalies beneath widespread shallow cover and fast-track the next generation of copper discoveries. The Company?s recent drilling focus at Jura (including Jura North) represents less than 5% of the broader 1,665 km² landholding, yet the project area contains over 112 mapped copper occurrences and the same Copper Creek basaltic stratigraphy and fault architecture that hosts high-grade, structurally controlled copper mineralisation regionally.

The regional program combined (i) an airborne gradiometer magnetic survey (approximately 11,000 line-km flown on 200 m line spacing) to map undercover fault corridors and alteration footprints, and (ii) a first-pass glacial till geochemistry survey (1,488 samples) to detect copper and multi-element pathfinder anomalies sourced from buried bedrock. Interpretation has identified multiple coincident anomalies where coherent copper?silver anomalies align with linear demagnetised features, interpreted to represent hematite-altered fault zones, an association that matches existing high-grade mineralisation intercepted in drilling throughout Copper Creek Formation. The standout result is a ~17 km long geochemical and geophysical anomaly (the ?Talisker?

anomaly), defined by a cluster of eight geochemically anomalous till samples, coincident with a major north?south fault zone that is observed to connect into the same fault architecture that hosts the Danvers deposit owned by White Cliff Minerals. This deposit has provided recent drill intercepts of up to 90m @ 4% Cu & 7.5g/t Ag from surface, and 30.5m @ 2.49% Cu from 7.62m. The strongest responses occur in areas with little to no outcrop and minimal historical exploration, supporting the Company?s view that significant copper systems may remain concealed beneath a thin (1?10 m) veneer of cover which shields most of the landholding.

Key program highlights include: 1,488 till samples collected; ten samples returning >1,000 ppm Cu, including a peak of 3,790 ppm Cu (0.38% Cu); and an extensive network of previously unmapped demagnetised corridors and structural features that materially expands the Company?s inventory of priority targets. Follow-up is planned to refine the anomalous zones through targeted infill sampling and ground-based geophysics, with the objective of rapidly converting corridor-scale anomalies into discrete, drill-ready targets. In 2025, Somerset completed the first regional glacial till geochemistry survey across the Coppermine Project, collecting 1,488 samples on a 1 km × 1 km grid (with tighter infill over the Jura area).

The program was designed as an objective, district-scale screening tool to detect copper and pathfinder element anomalies within glacial cover, and to prioritise undercover targets across highly prospective but historically underexplored Copper Creek basalts. Sampling targeted fresh, unweathered C-horizon material exposed in frost boils, which provides an effective medium in glaciated terrains because it can contain finely ground mineralised material transported from buried bedrock sources. The survey has returned multiple coherent copper and silver anomalies supported by a robust multi-element pathfinder signature consistent with hydrothermal, fault-hosted copper mineralisation.

Ten samples returned copper concentrations exceeding 1,000 ppm, including a peak value of 3,790 ppm Cu (0.38% Cu), which is considered exceptional for a first-pass, regional-scale till dataset. Elevated copper values show strong positive correlations with Ag, Se, In, Hg, Mo, Pd and sulphur?an element association characteristic of the ore-forming hydrothermal system recognised in existing drilling and surface datasets across the project. High sulphur values and Cu?Fe?S relationships are interpreted to reflect the presence of finely ground copper sulphides (including chalcocite and chalcopyrite) within the till, providing direct support that mineralised bedrock material is contributing to the anomalous geochemical response.

The inclusion of pathfinder elements (Ag, In, Se, Hg, Mo, Pd and S) materially improves confidence in anomaly classification by helping distinguish true hydrothermal copper signatures from background lithological variation, and by assisting in recognising potential zoning patterns (for example, Cu?Ag dominant cores with potential for more distal halo responses).
