The Denver Gold Group, Inc (DGG) connects global capital with global mining. It is organized as a Colorado nonprofit business association and represents seven-eighths of the world's publicly traded precious metal production and known mineral reserves and resources.
As the only independent and conflict-of-interest-free investment platform, Denver Gold Group is dedicated to the exclusive support of precious metal miners. DGG has a 33-year track record through every investment cycle. Underscoring the value and leverage it brings to the mining industry, fees to members have remained unchanged for eight years, and are on average nearly half the cost of other industry conferences.
DGG also supports and promotes various precious metal investment and education initiatives, often in collaboration with other mining and mineral industry business associations.
