Significant Discovery Made in Drilling at Tamarack Copper-Nickel Mine in the US

According to a report on Mining.com, Talon Metals announced that it had made a "historic" discovery at its Tamarack copper-nickel project in Minnesota.

The drilling encountered a cumulative 34.9 meters of massive sulphide orebody, marking the thickest intersection at the property. The previous record, set in 2022, was 23.4 meters.

Brian Goldner, Head of Exploration and Operations at Talon, stated that while grade data was not yet available, this was a "defining moment" for the Tamarack project.

The sulphide mineralization encountered in this drilling is similar to historical drillholes recently examined, which previously intersected 8.25 meters of ore with 12.62% nickel, 13.88% copper, and 17.95 g/t platinum group metals, in addition to gold, resulting in a nickel equivalent grade of 23.28%.

Since early February, Talon's exploration team has been conducting infill and extension drilling to provide a robust basis for a feasibility study. The first significant discovery from this work was the previously mentioned 8.25-meter massive sulphide intersection. The most recent discovery is four times that size.

"In my 19 years of working at Tamarack, I have never seen mineralization like this," Goldner said in a press release. "This clearly indicates that Tamarack is a world-class copper-nickel deposit."

The Tamarack project has an inferred mineral resource of 8.6 million mt at 1.73% nickel and 0.92% copper, and an indicated mineral resource of 8.5 million mt at 0.83% nickel and 0.55% copper.

Currently, Talon Metals is the majority shareholder (51%) of the Tamarack project, with Rio Tinto as the investment partner.
