Pinyon conducted a preliminary assessment of the economic benefits of the Moonlight-Superior Mining Project located in Plumas County, California. The Project is located approximately 10 miles northeast of Greenville, California in Plumas County, and approximately 100 miles northwest of Reno, Nevada.
The Project will develop copper, silver, and gold resources from three deposits in the County. Pinyon estimated economic impacts over project’s 15-year lifespan, with a total economic benefit of 689 new annual jobs and $234.9 million in annual Gross Regional Product in the first 10 years of operations. A press release from the Project is located here.
Pinyon used the capital expenses described and summarized in the Preliminary Economic Assessment (PEA) prepared by Global Resource Engineering (GRE) in 2025 for U.S Copper, along with the IMPLAN data and software system, to estimate the economic impacts in terms of economic output, employment, and Gross Regional Product (GRP) in Plumas County. Capital investments would primarily occur prior to operations during the construction phase but would also occur sporadically over the 15-year life of the Project. In total, capital investments are anticipated to be $1.3 billion in 2024 dollars.
