Talon Metals Marks Completion of Public Scoping Comment Period for Tamarack Mining Project
Tamarack’s Humboldt mill pivot delays the feasibility study to the second half of 2026 following the completion of the scoping study.
Talon Metals Corp. announced on September 14, 2026, the completion of the 60-day public scoping comment period for the Environmental Impact Statement (EIS) regarding the Tamarack Nickel-Copper-Cobalt Project. The Minnesota Department of Natural Resources (MN DNR) will now review the submitted comments and issue a Final Scoping Decision, which will dictate the scope of the subsequent state EIS.
Next regulatory steps include the preparation of a Draft EIS, a Final EIS, an additional public comment period, and the MN DNR's determination of EIS adequacy. The company continues parallel preparation for future state and federal permit applications.
Project design has been refined to reduce surface impacts, including a ~19-acre reduction in long-term surface facilities, enclosed ore handling, no exposed surface waste rock stockpiles, and zero in-state tailings generation or storage. Talon retains a 51% interest in Tamarack with an earn-in right to increase ownership to 60% in partnership with Rio Tinto.
Talon Metals Corp. (TLO) completed a scoping comment period, a procedural permitting milestone that was widely expected. The completion of this period does not alter the company’s financials, production guidance, or project timeline.
The primary driver of recent price action was the September 10 announcement that Tamarack ore will be processed at the existing Humboldt Mill instead of the greenfield Beulah facility. This strategic shift reduces upfront capital expenditure risk by leveraging existing infrastructure. The market had already priced in this development, with the stock rallying from $7.19 on August 13 to a high of $11.20 on September 10.
Market reaction to the latest release has been muted, reflecting the routine nature of the update. No guidance walk-backs or new financial metrics were disclosed.
Talon Metals Corp. (TLO) operates as a multi-asset U.S. nickel-copper company following the January 2026 acquisition of Lundin Mining's Eagle Mine and Humboldt Mill. The Eagle Mine is an underground nickel-copper operation in Michigan's Upper Peninsula that has been in operation since 2014. The Humboldt Mill is a conventional flotation processing facility in Michigan, which has been selected to process ore from the Tamarack Project. The Tamarack Project is a high-grade nickel-copper-cobalt project located in central Minnesota and is currently in the environmental review phase. Additionally, the company holds a Michigan Land Package of approximately 400,000 acres adjacent to the Eagle Mine and Humboldt Mill, hosting exploration targets including Boulderdash and Roland.
