Brian Goldner

Brian Goldner is Chief Exploration Officer of Talon Metals Corp. (TSX: TLO), the junior explorer advancing the Tamarack nickel-copper-cobalt project in central Minnesota. He runs the multi-rig drill programs that have delivered Tamarack's highest-grade results to date, which makes him a first-hand source for investors tracking one of the most advanced nickel exploration projects in the United States.

He is a Tamarack specialist by training. Goldner holds geology and geography degrees from Gustavus Adolphus College and completed his master's thesis on the Tamarack Intrusion — the geological body that hosts the deposit — at the University of Minnesota Duluth. He spent about 15 years with Rio Tinto's nickel exploration team, much of it at Tamarack, and was seconded to Talon from 2018 before taking over as Vice President of Exploration on a permanent basis in July 2021. During the secondment he helped lead the drilling that discovered the CGO East and CGO West massive sulphide zones — rock made up largely of metal sulphide minerals, the high-grade material miners seek — outside the deposit's known resource at the time.

Leading Talon's exploration since then, he directed the campaigns that established the Vault Zone below the original Tamarack Resource Area in May 2025 and confirmed a fourth mineralized level in it by December 2025. In September 2026, Talon reported a record 46.43-metre intercept in drill hole 25TK0562A assaying 13.37% nickel and 16.54% copper, along with cobalt, platinum, palladium and gold. An assay is a laboratory measurement of the metal content in drilled rock.

His approach pairs geophysics with in-house drilling: the team tests geophysical targets hole by hole and updates the geological model after every result. Goldner has described Tamarack in three dimensions, with dense sulphide liquid draining downward into deeper pools as the intrusion cooled — the model that led the drillers to the Vault Zone beneath the original resource. He also favours publishing complete data; after the record intercept, he said the individual assay result for every sample was released so the grades could be judged directly.

Investors can follow Goldner through Talon's news releases, his recurring presentations at the Metals Investor Forum, and interviews such as his November 2025 conversation with analyst Robert Sinn on step-out drilling (holes drilled beyond the known resource to test for new mineralization). The project has drawn US government support for exploration, including a US$20.6 million award, and his drill programs are a direct read on whether Minnesota yields a domestic source of battery metals.
