Join the Asheville Museum of History (AMoH) Wednesday, September 20 at 9AM as we hike to a former mica mine near Burnsville, North Carolina. This event is free but registration is required. Carpooling is necessary as parking is limited.
Join us as we explore the geologic and human history of mining in the Spruce Pine region. We are led by Dr. William Miller, a geologist, and Trevor Freeman, public programs director for the Asheville Museum of History. Local resident John Bennett may join us to discuss some his family history and more about the local mines nearby.
The Mine
The Ray Mine is located in one of scores of igneous rock bodies in the Spruce Pine mining district which began as magmas that were injected into an existing bedrock formation known as the Ashe Metamorphic Suite 375-400 million years ago. The intrusion is made of coarsely crystalline granodiorite which is composed of feldspar, quartz, and muscovite mica, plus lesser amounts of other minerals, including tourmaline, beryl, and apatite.
The Ray was sporadically mined mainly for high quality muscovite from about 1867 until the 1940s. Compared to its sister intrusions currently being mined for high purity quartz and feldspar in Spruce Pine, the Ray is rather puny but one of few designated mineral collecting localities in the National Forest where visitors are allowed to take home the minerals they find on the ground surface and can easily carry.
Nine small shafts/cuts occur at the mine, but they are either partially fenced off and filled with rubble or overgrown with vegetation. The mine site now looks like most other nearby hills but with mineral and rock specimens strewn about.
