Untested Deep Targets at Jura Pose Both Opportunity and Exploration Risk

Deepening Mineralisation at Jura

Somerset Minerals Limited (ASX – SMM) has unveiled compelling new geophysical evidence from its Jura Prospect within the Coppermine Project in Nunavut, Canada. The recent induced polarisation (IP) and resistivity surveys reveal a mineralised copper zone extending to at least 600 metres below surface, significantly deeper than previous drilling which reached around 160 metres. Notably, the conductivity of this zone strengthens with depth, a geophysical hallmark often associated with thicker and higher-grade copper sulphide mineralisation.

These findings build on recent drilling successes at Jura North, where intercepts such as 42.7 metres at 2.69% copper and 59.4 metres at 1.50% copper have already demonstrated the prospect’s potential. The geophysical data now suggest that this mineralised corridor continues well beyond the depths tested to date, opening the door to a potentially substantial underground resource.

Untapped Parallel and Southern Targets

Beyond the main mineralised zone, the surveys have identified a parallel hanging wall zone exhibiting low resistivity over approximately 400 metres of strike length, which remains untested by drilling. Additionally, a new target at Jura South has been delineated by a resistivity low extending at least 600 metres below surface, coinciding with a modeled fault zone but lacking any historic drilling or outcrop exposure. These targets represent exciting opportunities to expand the footprint of mineralisation within the Coppermine Project.

Complementing the resistivity data, the IP survey has highlighted highly chargeable anomalies proximal to known mineralisation, possibly indicating coarser-grained sulphides or distinct mineralisation styles such as flow-top replacements. One particularly large chargeable anomaly between survey areas remains poorly constrained but is considered a high-priority target for further investigation.

Strategic Exploration and Upcoming Catalysts

Somerset’s Managing Director, Chris Hansen, emphasised the scale potential of Jura and the broader Coppermine Project, noting that Jura accounts for less than 5% of the company’s extensive 1,665 square kilometre landholding. The company is advancing plans for deeper step-out drilling to test the down-dip extensions and parallel lodes identified by geophysics. Assay results from six recently completed drill holes are expected within the next two to four weeks, while a regional airborne magnetic survey is nearing completion, promising a pipeline of new targets across the belt.

The Coppermine Project’s geological setting is analogous to the prolific Keweenaw Peninsula copper deposits in Michigan, featuring structurally controlled, high-grade copper mineralisation hosted in basalt flows and fault zones. Somerset’s disciplined approach integrates petrographic analysis, geophysics, and drilling to systematically unlock this potential.

Looking Ahead

With multiple untested targets and encouraging geophysical signatures, Somerset Minerals is poised to accelerate exploration at Coppermine. The combination of expanding mineralisation at depth, new parallel zones, and regional targeting efforts could transform the project into a multi-deposit copper camp, attracting significant market attention as results unfold.
