Somerset Minerals Confirms New High-Grade Copper-Silver Discovery at Talisker

Maiden Drilling Confirms Blind Copper-Silver Discovery

Somerset Minerals Limited (ASX:SMM) has kicked off its maiden reverse circulation (RC) drilling program at the Talisker copper target within its flagship Coppermine Project in Canada with striking results. The first two holes, TARC0003 and TARC0008, both intercepted thick zones of high-grade copper-silver mineralisation beneath a thin glacial cover, confirming a new, largely blind copper discovery.

TARC0003 returned 36.6 metres at 1.62% copper and 11.8 grams per tonne silver from 22.9 metres, including a standout 9.1 metres at 4.39% copper and 28.8 grams per tonne silver. Meanwhile, TARC0008 intersected a broader mineralised envelope of approximately 79 metres, including 38.1 metres at 1.27% copper and 7.4 grams per tonne silver from 41.15 metres, with peak assays hitting 6.32% copper and 42.7 grams per tonne silver over 3.05 metres. Both holes were drilled just 80 metres apart on separate section lines, underscoring the consistency of the mineralisation.

Talisker: A Systematic Approach Pays Off

What makes this discovery particularly noteworthy is that Talisker had never been drill tested before, despite being a large 17-kilometre-long corridor defined by coincident geochemical and geophysical anomalies. The mineralisation lies concealed beneath 1 to 10 metres of glacial cover, making it a challenging target. Somerset’s success is a testament to its meticulous, multi-disciplinary targeting approach that integrated regional till geochemistry, high-resolution magnetic geophysics, detailed structural mapping, and infill soil sampling.

Managing Director Chris Hansen described the results as "phenomenal," highlighting that the discovery validates the company’s targeting methodology and boosts confidence in the roughly 20 other analogous targets across the district. The Talisker corridor sits only about 4 kilometres from White Cliff Minerals’ Danvers deposit, which recently reported its own high-grade copper intercepts, suggesting a highly prospective regional structural setting.

Ongoing Drilling and Exploration Upside

The maiden RC program is well underway, with 14 holes completed for approximately 2,200 metres, testing just a central 2-kilometre segment of the Talisker corridor. Assays for the remaining 12 holes are expected on a rolling basis over the coming weeks. Somerset holds permits for up to 100 drill holes, enabling immediate follow-up drilling to expand and delineate the discovery.

The company is now focused on integrating the drilling results with detailed geological logging, multi-element geochemistry, and pending laboratory assays from a 641-sample infill soil program to refine the geometry of the mineralisation and prioritise future drill targets along the corridor. With the broader 17-kilometre Talisker corridor remaining almost entirely untested, the discovery opens a significant pipeline of drill-ready exploration opportunities.

Regional Context and Project Scale

Somerset’s Coppermine Project is one of the largest landholders in the region, covering 1,677 square kilometres in Nunavut’s Kitikmeot region. The geology is analogous to the Keweenaw Peninsula copper deposits in Michigan, known for high-grade native copper in continental flood basalts. The project hosts multiple high-priority targets beyond Talisker, including the Jura, Laphroaig, and Ardbeg districts, each showing promising copper-silver mineralisation supported by historic and recent sampling and drilling.

The Talisker discovery adds a compelling new chapter to Somerset’s exploration story, with the maiden drilling results providing a robust foundation for resource development. The company’s systematic approach to exploring beneath glacial cover and its ability to convert geochemical and geophysical anomalies into tangible drill success distinguishes it in a region that has seen limited exploration since the 1960s.
