A "minor gold deposit" refers to a low-grade gold deposit that has a relatively small amount of gold. Synonyms for a minor gold deposit include marginal gold deposit, modest gold deposit, and small-scale gold deposit. These terms all describe deposits that have limited value or potential for commercial mining operations. Other related terms include "micro-deposit" and "sub-economic deposit". It is important to note that a minor gold deposit can still provide opportunities for small-scale mining operations and can contribute to local economies. However, they are generally not viewed as economically viable for larger-scale mining due to their limited gold content.
