How much gold and silver is left to be mined in California?

As of now, the exact amount of gold and silver left to be mined in California is difficult to determine, as it depends on various factors including new exploration technologies and economic viability. Historically, California has produced significant amounts of both metals, especially during the Gold Rush era. Current estimates suggest that while large deposits have been depleted, there are still undiscovered reserves, particularly in less accessible areas. However, ongoing mining operations and environmental regulations can impact the feasibility of extracting these remaining resources.
