Stillwater West PGE (Montana)

Home / Stillwater West PGE (Montana)

In June 2017, Group Ten Metals entered an agreement to acquire a 100% interest in the Stillwater West project, consisting of 282 claims adjacent to, and contiguous with, Sibanye Gold’s Stillwater mine in south central Montana, USA. Sibanye acquired the operation, which is the highest-grade platinum group element (PGE) producer in the world and the largest outside South Africa and Russia, through a US$2.2 billion May 2017 acquisition of Stillwater Mining Co. Group Ten’s acquisition of the highly-prospective Stillwater West project positions the Company as the second-largest land holder in the Stillwater ultramafic complex. The acquisition includes a substantial exploration database that is currently under review by the Group Ten technical team.

The Stillwater and East Boulder mines occur along the Johns-Manville (J-M) Reef, the richest PGE deposit in the world with over 19.9 million ounces of proven and probable palladium and platinum ore reserves at an average grade of 15.64 grams/tonne)1. Group Ten’s Stillwater West project covers over 2,200 hectares (22 square kilometers) in two claim groups with each parcel including over 17 kilometers of strike length parallel to the J-M Reef within the Stillwater layered ultramafic complex.

Past work on the Stillwater West project includes broad soil and rock geochemical sampling, geologic mapping and some initial drilling. Results of these programs demonstrate the occurrence of multi-kilometric scale areas of highly anomalous palladium, platinum, gold, copper and nickel values in soil and rock samples and resulted in the identification of multiple targets with a primary focus on high-grade PGE and gold deposits.
The acquisition follows our strategy of acquiring high-quality assets in world-class districts and complements our portfolio of holdings in the Kluane Ultramafic Belt in Yukon adjacent to Wellgreen Platinum, and in the Rainy River district of Ontario adjacent to First Mining Finance’s Goldlund project. Prior work on the project generated significant geological and exploration data which will be instrumental in Group Ten’s advancement of the project.
