The Ray Mica Mines are located on Hurricane Mountain, 4.0 km (2.5 miles) SSE of Burnsville (coordinates of record), in the Bolen's Creek area, on National Forest land.

Mineralization is a mica-rich pegmatite. Additional commodities include U & Th.

Workings include 10 verticle shafts, which remain open.

See Forest Service for designated area for collecting.

Attention North Carolina rockhounds! The Ray Mica Mine site in Burnsville is now posted as a day use only area. It is also posted that entering any mine no matter depth or distance is under 'Emergency Temporary Closure', adding some confusion on whether surface collecting is still allowed.

According to a local rock shop owner in Spruce Pine, the sign was posted recently because a 'renegade' hunter camped up there for about a week, creating quite a mess outside the usual dig area. There are now blue flags on the trees, walking up the creek on the right which I'm assuming are creating an ok collecting area.

Collecting at this site could be on it's toes right now with the Forest Service, and installing their new signs could be a way a restricting it in the future.

Let's not let this site turn into the once Walker Creek Kyanite site that is now subjected to strict, no collecting laws.
