Somerset Confirms New Copper Discovery With 36.6m at 1.62% Cu First Two Holes
Somerset Minerals confirms new copper-silver discovery at Talisker with first two holes
Somerset Minerals (ASX:SMM) has confirmed a new copper-silver discovery at the Talisker target within its flagship Coppermine Project in Nunavut, Canada, with assay results from the first two holes of its maiden reverse circulation (RC) drill program. Both holes intersected thick, high-grade mineralised zones beneath thin glacial cover along a corridor that had never been drilled before.
The headline intercepts are TARC0003: 36.6m @ 1.62% Cu & 11.8g/t Ag from 22.9m, including 9.1m @ 4.39% Cu & 28.8g/t Ag, and TARC0008: 38.1m @ 1.27% Cu & 7.4g/t Ag from 41.1m plus 35.1m @ 1.01% Cu & 4.7g/t Ag from surface. These represent the first-ever drill testing of the ~17km Talisker corridor — a genuine greenfields discovery built systematically from regional geochemistry, geophysics, and structural mapping over the past 17 months since project acquisition in April 2025.
The discovery validates Somerset’s targeting methodology across a district-scale land position of 1,677km², where the company holds the largest tenure over the prospective Copper Creek Formation basalts. With 12 holes still awaiting assays and permits in place for up to 100 holes, the news flow runway is clear and the exploration upside remains largely untested.

Breaking down the maiden drill results
Both holes returned thick mineralised envelopes extending over significant downhole lengths. TARC0003 intersected two zones of copper-silver mineralisation within a broader ~53m mineralised envelope, while TARC0008 was mineralised over a ~79m downhole envelope from surface, interrupted by only 6.1m of internal low-grade material.
| Hole ID | From (m) | Width (m) | Cu (%) | Ag (g/t) |
|---|---|---|---|---|
| TARC0003 | 22.9 | 36.6 | 1.62 | 11.80 |
| including | 36.6 | 9.1 | 4.39 | 28.82 |
| including | 44.2 | 1.5 | 9.09 | 64.60 |
| and | 70.1 | 6.1 | 1.29 | 2.68 |
| TARC0008 | 0.0 | 35.1 | 1.01 | 4.67 |
| including | 24.4 | 6.1 | 4.50 | 21.35 |
| and | 41.1 | 38.1 | 1.27 | 7.43 |

What stands out
- Peak assay: 9.09% Cu & 64.6g/t Ag in TARC0003 (1.5m interval at 44.2m depth)
- Near-surface mineralisation: TARC0008 mineralised over ~79m downhole from surface, with two high-grade zones separated by minimal internal dilution
- Consistent silver association: All mineralised zones carry elevated silver grades, with individual intervals reaching 64.6g/t Ag and broader zones averaging 28.8g/t Ag
- Spatial continuity: Two holes drilled 80m apart on separate section lines both returned thick, high-grade intercepts, demonstrating mineralisation continuity along strike
How a “blind” discovery was built from scratch
Talisker is a greenfields discovery in the truest sense: mineralisation is largely concealed beneath 1–10m of glacial cover, with no outcrop, no historical drilling, and no visible surface expression across most of the corridor. The strongest geochemical responses occur in areas with little to no outcrop and no prior exploration. This is “blind” mineralisation — invisible from the surface, requiring systematic targeting to locate and drill-test.
The discovery workflow de-risked the target layer by layer. Regional till geochemistry in 2025 identified anomalous copper clusters across the district. High-resolution magnetic geophysics in 2025 mapped a major north-south striking fault zone with a demagnetised signature interpreted to reflect intense hydrothermal alteration over widths up to 300m. Detailed structural mapping in 2026 refined the fault geometry, and a 641-sample infill soil program in June 2026 outlined a spatially cohesive 3.4km anomaly centre along the corridor.
Over 17 months, from project acquisition in April 2025 to the current discovery in August 2026, the company systematically reduced the search space from 1,600km² down to a central 3.4km target zone. Surface rock chip sampling across the corridor in June 2026 returned assays up to 36.4% Cu & 214g/t Ag, confirming high-grade mineralisation at surface where outcrop exists.
The discovery validates the repeatable nature of this targeting methodology across Somerset’s broader land position. The company has identified ~20 analogous targets across the district using the same workflow, and the success at Talisker de-risks the exploration potential of these untested targets.
Chris Hansen, Managing Director
“…To convert that dataset into a copper discovery with the first two holes reported is emphatic validation of our targeting methodology, and it gives us enormous confidence in the pipeline of the ~20 other analogous targets we hold across the district. This program is testing just a central 2km of a ~17km corridor that had never seen a drillhole.”
The neighbourhood — proximity to White Cliff’s Danvers
Talisker sits only ~4km from White Cliff Minerals’ (ASX:WCN) Danvers deposit, on a linked regional structure. The Talisker fault connects into the Teshierpi Fault Zone that hosts Danvers, reinforcing the structural setting’s prospectivity. In June 2026, White Cliff reported new high-grade copper results at Danvers, where drillhole DAN26012 returned 19.81m @ 6.64% Cu from 152.4m, including 3.05m @ 17.68% Cu.
The proximity to Danvers does not guarantee comparable results at Talisker. However, the structural linkage and similar geological setting support the broader district’s copper potential.
What’s next for Somerset
The news flow runway is clear and the exploration capacity is already in place. The key near-term catalysts include:
- Rolling assay results: Assays for the remaining 12 holes (~2,200m drilled to date) expected over the coming weeks
- Final soil assays: Laboratory assays from the 641-sample infill soil program pending, which will refine the anomaly geometry and prioritise follow-up targets
- Discovery refinement: Integration of drilling results, geological logging, and multi-element geochemistry to define mineralisation continuity and geometry
- Immediate follow-up capacity: Permits in place for up to 100 holes, allowing immediate drill response to successful results
The maiden program is testing only a central ~2km of the ~17km Talisker corridor. The bulk of the corridor remains untested, representing significant exploration upside that can be systematically drill-tested as results from the current program are integrated and interpreted.

Why this matters for investors
Somerset has confirmed a new high-grade copper-silver discovery on the first two holes drilled along a 17km corridor that had never been drill-tested. The discovery is underpinned by a proven, repeatable targeting methodology that systematically identified mineralisation beneath glacial cover, reducing the search space from 1,600km² to a 3.4km anomaly centre over 17 months. The methodology is now being applied to ~20 analogous targets across the district.
The near-term catalyst pipeline is strong. With 12 holes awaiting assays, permits for up to 100 holes, and only ~2km of a 17km corridor tested, the company has the permitting, drilling capacity, and exploration runway to follow up this discovery immediately. This is early-stage exploration and no resource has been defined, but the discovery de-risks the broader exploration thesis and validates the company’s systematic approach to targeting blind mineralisation at district scale.
