That's from the old mercury mines in the area and erosion from naturally enriched mercury soil/runoff from naturally enriched geothermal springs, not the McLaughlin gold mine.
(The Wikipedia article is for the Sulfur Bank Mercury Mine. The McLaughlin mine is referenced due to how gold was discovered, but it's about 15 miles away)
