(Vale, OR) -- The Bureau of Land Management has approved the Grassy Mountain Gold Mine near Vale in Eastern Oregon. State permits are still needed before the project can move forward. The BLM fast-tracked the project under President Trump's directive to increase mining in the U.S. The mine will cover 470 acres and use a cyanide solution to extract gold and silver from the soil. About two-billion dollars in gold and silver are expected to be mined over the next 20 years.
