Keystone & Edison Project
The Keystone Project consists of 137 BLM lode claims and the Edison Patented claim covering areas of prospective LCT-pegmatites. The claims are located near the township of Keystone, an area is famous for the production of lithium in the form of very large spodumene crystals and also near the Edison and Etta lithium producing mines. The Etta Mine operated for >60 years (1898 to 1960), and was at times, the main source of spodumene in the world; recording a head grade of c. 6.0% Li2O and yielded up to >14m long spodumene crystals; reportedly the largest ever mined worldwide.
The Edison Lithium Mine is located on a patented claim. This historic mine was first worked in 1917 with subsequent sporadic periods of mining. The mine consisted of open cut and underground operations.
