Berkeley Springs

West Virginia, United States · Open Pit

Operating
Silica Sand
Overview
The Berkeley Springs site includes 4,435 acres of owned land with subsurface mineral and water rights. The initial discovery and mining of the Oriskany sandstone deposit near Berkeley Springs occurred in the late 1800s.
Production
The mine produces whole grain, ground, and fine ground silica. These products serve a variety of markets, including glass, building products, foundries, chemicals, and fillers and extenders. The addition of limestone and sandstone aggregates serves the construction materials sector in the eastern United States.
Processing
The Berkeley Springs facility employs hard rock mining methods to extract high-purity sandstone. The processing plant utilises primary, secondary, and tertiary crushing, grinding, flotation, dewatering, fluid bed drying, mechanical screening, and rotary drying. The plant uses propane, fuel oil, and electricity in its processes. In addition to silica products, the facility produces a synthetic magnesium-silica product called Florisil and has expanded its operations to include a limestone processing operation.
Expansion
Expansion of blasting operations to extend mine life; added a limestone processing operation.

Mine life
21 years
Production
The project has a Mineral Resource estimate of 10.3 million tonnes at 1.03% Li2O. This is comprised of 6.1 million tonnes at 1.25% Li2O in the Indicated category and 4.1 million tonnes at 0.76% Li2O in the Inferred category. The project also has a maiden rubidium resource of 8.3 million tonnes at 0.27% Rb2O. An offtake agreement has been executed with LG Energy Solution for 25% of the first five years of production. The PEA highlights a potential for 207,000 tonnes per year of SC5.5 spodumene production.
Processing
The project will utilise a DMS (Dense Media Separation) concentrator to produce a 5.5% Spodumene Concentrate. A one-tonne spodumene concentrate sample from the Seymour project has undergone pilot testing at EcoPro Innovation's facility in South Korea, successfully producing battery-grade lithium hydroxide. This testing confirmed that Seymour concentrates are suitable for producing battery-grade lithium hydroxide using conventional processing techniques.
Equipment
The mining fleet outlined in the Preliminary Economic Assessment includes two 250-tonne excavators. One excavator will be used for bulk waste movement, while the other will focus on mining feed material. The project layout includes a processing plant, mining infrastructure, and water management infrastructure.
