Talon Metals has revealed a sulphide discovery of over 8.25m during its drilling at the Tamarack Nickel-Copper-Cobalt Project in Minnesota, US.
This development emerges as part of a feasibility study being conducted by Talon Metals, which holds the majority interest in the project.
The drill hole, initially inspected at a 649m depth, was extended to assess a borehole electromagnetic signal detected in the data.
According to Talon Metals, the mineralisation was encountered at a depth of 707.75m, with sulphide content reaching 95%, pointing to potentially high-grade nickel deposits. The intercept lies roughly 150m below and 50m south of previously identified mineralisation within Tamarack’s resource zone.
This new finding could represent an expansive zone for massive sulphides, given the minimal drilling activity in the vicinity, said the company. A borehole EM survey on the extended drill hole is said to have found a strong off-hole conductor, leading to additional drilling activities targeting this anomaly.
Talon Metals COO and chief exploration officer Brian Goldner said: “Our exploration team has done it again, using borehole EM to guide the in-house drilling capability resulted in an exciting discovery in an area that is outside of the Tamarack resource.
“Our mineralisation model for Tamarack is that the nickel mineralisation was draining down through the intrusive system and pooled up at the bottom of the MSU near the 14TK0171 intercept. Instead of terminating there, this drilling clearly shows that the MSU continued to drain further down into a new area that currently has a lack of drilling.”
The Tamarack project aims to offer domestic nickel supply for electric vehicle manufacturing. Operated through a joint venture with Rio Tinto, the project encompasses Tamarack North and South Projects covering approximately 31,000 acres of land.
Talon Metals has earned a 51% stake in the project by fulfilling financial and developmental criteria set with Rio Tinto, including cash payments and exploration investments. The former plans to raise its ownership to 60% by completing a feasibility study and further financial obligations by March 2026.
Under their operational agreement, Talon Metals leads the exploration strategy. Once Talon Metals’ ownership reaches 60%, Rio Tinto must either contribute financially or dilute its interest.
Talon Metals possesses full control over the off-take agreements regarding product sales.
