California-Engels Mining Company (CAEN), founded in 1922 and headquartered in Roseville, California, owns and leases mineral and timber properties primarily in the Lights Creek Mining District of Plumas County in northern California; its core assets include 36 patented lode mining claims covering 736 acres plus 339 acres of other patented lands at the Engels and Superior copper mines, alongside a certified tree farm, rock aggregate resources, and interests in five additional patented lode claims spanning 100 acres in the Genesee Mining District. The company generates revenue from timber sales, land and rock aggregate leasing, mining leases for copper, gold, and silver extraction, rental income, bookkeeping services, and investment activities, with the Engels Mine holding an estimated mineral resource of 19 million tons at 0.63% copper grade containing 487 million pounds of contained copper. It historically pioneered the first all-flotation copper mill in the United States in 1915, supporting significant local employment and dividends during peak operations that shipped ore to smelters in Utah. Recent financials reflect strong earnings growth of 487.6% over the past year on revenue of approximately $88,600 from trailing twelve months, with a market capitalization around $2.8 million and ongoing efforts to advance mine resumption amid stable stock pricing near $4 per share as of late 2025. The company maintains continuous operations as lessor without noted recent acquisitions, partnerships, funding rounds, or major strategic shifts in the last 1-2 years, focusing on resource development in the western United States non-energy minerals sector.
