I'm not entirely sure, but the Kings River Pyrg appears to be located on the other side of Thacker Pass from where the mine will be. Meaning: it's habitat is on the "south side of the road", which would place it on the west side of the ridge upon which the mine will be sited on the east side.

Also...from one of the earlier links: "Old growth sagebrush"? LOL! [Though I do believe that sagebrush is an often overlooked, yet important plant in the intermountain west...]
