Project Description

Pacific Soda, LLC owns rights to mine trona resources on private lands and leased BLM administered lands in the Kemmerer Field Office in Sweetwater County, Wyoming. 
The proposed mine permit area includes two BLM leased sections and three private sections, located south of I-80 and west of Wyoming State Highway 530, south of the town of Green River, Wyoming. 
The Mine Plan, if approved by the BLM, would allow Pacific Soda to construct mining facilities and employ solution mining technologies to develop their BLM leased minerals by mining trona beds 2,300 feet below the surface and processing that trona for market.
Trona is a mineral used to make baking soda as well as soda ash, which is a component of lithium batteries and glass used for solar energy. Pacific Soda estimates that approximately 23.5 million tons of trona are in reserve on each section of land within the proposed project area, that mining would occur on each section 9 to 10 years, and that mined trona would be refined to produce approximately 6.0 million metric tons of marketable soda ash per year and 440,900 metric tons of sodium bicarbonate (baking soda) per year.
