Somerset Minerals Traces Copper Across 1.6km With 91% of Anomaly Untested
Key Takeaways
- Twelve holes from Somerset Minerals' maiden RC program at Talisker have confirmed copper-silver mineralisation across 1.6km of strike, with standout intercepts including 30.5m @ 0.71% Cu from 126.5m (TARC0010) and 18.3m @ 0.66% Cu from 15.2m (TARC0004).
- The 1.6km tested represents only 9% of the full 17km Talisker anomaly, with the main demagnetised fault zone — interpreted as the highest-priority target — remaining largely untested by drilling.
- TARC0010 extended high-grade copper approximately 240m north of the original discovery holes, while TARC0004 confirmed mineralisation approximately 1km to the south, demonstrating genuine lateral continuity.
- Somerset holds permits for up to 100 holes across the licence area, with assays for the final two holes (TARC0013 and TARC0014) expected within 2–3 weeks and a significantly larger follow-up program being planned.
- Beyond Talisker, the 1,677km² Coppermine landholding hosts three additional high-priority targets — Jons Pit, Skye, and Jura — each with high-grade surface samples and the same basalt-hosted structural setting.
Copper confirmed across 1.6km — and Somerset has barely scratched the surface
Twelve holes reported to date have traced copper-silver mineralisation across 1.6km of strike at the Talisker target, yet that represents roughly 9% of the 17km Talisker anomaly. Somerset Minerals (ASX: SMM) announced the latest batch of assay results from its maiden reverse circulation (RC) drill program at the Talisker copper-silver target, part of the company’s flagship Coppermine Project in Nunavut, Canada.
The maiden program comprised 14 holes for 2,170m in total, with assays for the final two holes (TARC0013 and TARC0014) still pending. What the first 12 holes have confirmed is that ore-grade copper is present across a strike extent that, on the scale of the full anomaly, has barely been tested.

Standout intercepts build on the August discovery holes
The latest batch of results includes ten holes, of which eight returned copper above the reporting cut-off. Three results stand out.
New assays — key intercepts from this release
- TARC0010: 30.5m @ 0.71% Cu & 2.7 g/t Ag from 126.5m, including 12.2m @ 1.58% Cu & 5.8 g/t Ag from 143.3m, including 4.6m @ 3.38% Cu & 12.6 g/t Ag from 146.3m — the deepest high-grade copper intersected at Talisker to date, approximately 240m north of the discovery holes
- TARC0004: 18.3m @ 0.66% Cu & 1.2 g/t Ag from 15.2m, including 4.6m @ 1.78% Cu & 3.5 g/t Ag from 29.0m, including 1.5m @ 4.95% Cu & 9.7 g/t Ag from 30.48m — approximately 1km south of the discovery area
- TARC0002: 18.3m @ 0.44% Cu & 2.2 g/t Ag from 1.5m — directly beneath a surface float sample grading 25.8% Cu & 191 g/t Ag

Context from the August discovery holes
Readers who missed the August announcement should note the benchmark those results set. TARC0003 returned 36.58m @ 1.62% Cu & 11.8 g/t Ag from 22.86m, while TARC0008 returned 38.1m @ 1.27% Cu & 7.4 g/t Ag from 41.15m. Both holes intersected two distinct zones of mineralisation within broader mineralised envelopes, establishing the foundation that subsequent holes have now extended to the north and south.
For readers wanting the full picture behind those benchmark intercepts, our full explainer on the August Talisker discovery holes covers the peak assay grades, dual mineralised zones, and the geophysical targeting methodology that placed those first two drill collars.
What makes Talisker a genuine district-scale opportunity
To understand why the untested ground matters, it helps to understand what the Talisker anomaly actually is. The 17km feature is a coincident geochemical and geophysical anomaly, meaning both soil chemistry and airborne magnetics point to the same north-south fault corridor. That combination is significant: it suggests a large, coherent mineralising system, not isolated surface showings.
The key to the system is the demagnetised zone at its core. The basalts hosting Talisker are normally strongly magnetic. Where hot, copper-bearing fluids have moved through the fault zone, they can destroy the magnetic mineral magnetite and convert it to non-magnetic hematite, leaving a “magnetic low” in the data. Somerset interprets this large demagnetised zone as the footprint of intense hydrothermal alteration, and its core as the most likely location of the largest volume of mineralising fluid flow. In plain terms: the non-magnetic zone is where the plumbing was biggest.
Here is the critical point for investors. The maiden program deliberately targeted the periphery of that demagnetised zone, drilling on its margins where outcrop helped guide the early drill pads. Only two drill sections have tested the main demagnetised zone along the full 17km anomaly, and both intersected copper. The core of the system — the highest-priority target — remains largely untested. Geological analogies to consider (noting these are proximate comparisons, not guarantees) include the nearby Danvers deposit 4km to the south (90m @ 4% Cu from surface, ASX:WCN) and Jura (42.7m @ 2.69% Cu), both in the same structural setting.
Chris Hansen, Managing Director
“The main demagnetised fault zone at the heart of the anomaly, which we interpret as the most intensely altered part of the system, remains largely untested. That is the next opportunity. We believe the first 14 holes have materially de-risked the system, and proven ore-grade copper occurs at Talisker…”

What’s next — a larger program across four targets
The near-term pipeline is tangible and already permitted. Somerset holds approvals for up to 100 holes across the licence area, removing a key execution risk that often delays junior explorers at this stage.
Immediate catalysts
- Assays for TARC0013 and TARC0014 are expected within 2–3 weeks — both holes intersected wide zones of alteration, which the company flags as a positive indicator
- A significantly larger drill program is being planned to test the main demagnetised Talisker zone, with approximately 15km of strike remaining undrilled along the anomaly
- Maiden drill tests are planned for the Skye and Jons Pit targets
The district beyond Talisker
Talisker sits within a 1,677km² Coppermine landholding that hosts three additional high-priority copper targets, each with its own high-grade surface story:
- Jons Pit: Located ~5km south of current drilling; flow-top replacement style mineralisation that has never been drill tested; surface samples grading up to 19.85% Cu & 13.4 g/t Ag
- Skye: A Priority-1 coincident soil and magnetic anomaly approximately ~60km east of Talisker; maiden rock chips returned up to 46.3% Cu & 25.1 g/t Ag (massive bornite hosted in sandstone)
- Jura: Approximately ~60km east of Talisker; a 7km high-grade trend where 2025 drilling returned 42.7m @ 2.69% Cu from 15.2m
The spread of high-grade copper across targets 5km to ~60km apart, in the same basalt sequence and structural setting, is what underpins the district-scale character of the project.
The Jura copper trend extends over 7km and shares the same basalt-hosted fault architecture as Talisker, with high-grade surface samples and confirmed drill intercepts establishing it as a standalone target rather than a footnote to the Talisker program.
