Project Background 

Pinson is an underground mine located outside of Golconda, Nevada in Humboldt County. Underground test mining was conducted in the early 2010’s following the completion of open-pit operations that lasted between 1980 and 1999. Since Osgood Mining Company, LLC acquired the Mine in 2015, it has been placed on care and maintenance. Sunstone provided environmental support for the Mine on all aspects of permitting and compliance from 2016 through early 2020. 

Other Projects 

Pit Lake and Monitor Well Sampling 

Sunstone supported Osgood Mining Company by sampling the pit lake and monitor wells between 2016 and 2020. Pinson has one pit lake at the mine that requires annual sampling and multiple groundwater monitor wells that require quarterly sampling. Utilizing a pudgy, Sunstone collected three water quality samples at different depths in the lake. Using a sonde device, we captured water quality data at every foot of depth. We compiled and submitted this data in reports to the agency in compliance with the Water Pollution Control Permit.
