Integra Resources (ITRG) said Thursday the US Bureau of Land Management has accepted an updated mine plan of operations for the DeLamar gold-silver project in Idaho.

The plan incorporates nearly three years of environmental studies and proposed activities, which will now serve as the basis for a federal environmental review, the company said. The plan prioritizes siting mine features on previously disturbed ground, reduces potential water impact, and leverages processing capacity at its Florida Canyon mine, Integra added.

The company said it will now begin work on its environmental impact statement with the publication of Notice of Intent, and expects to release an updated feasibility study for DeLamar in Q4.

Shares of the company were down more than 2% in recent premarket activity Thursday.
