A new study has revealed the US states where prospectors are most likely to find gold, with California ranking first due to its high concentration of known gold locations.
The analysis by Coinfully, a company specialising in rare coin buying and appraisals, used data from the United States Geological Survey Mineral Resources Data System. Researchers examined locations where gold ore has been found or produced as a commodity and calculated the number of sites per 1,000 square miles in each state.
Top 10 states by gold location density
- California leads the rankings with 10,373 gold locations across 155,779 square miles, giving it 66.59 sites per 1,000 square miles. The state’s strong showing reflects its long association with the 1849 Gold Rush and the mineral-rich Sierra Nevada region.
- Washington ranks second, recording 2,271 locations over 66,455 square miles. Its density of 34.17 sites per 1,000 square miles places it firmly behind California but ahead of all other states.
- Oregon takes third place with 3,015 locations across 95,988 square miles, resulting in 31.41 sites per 1,000 square miles.
- Nevada ranks fourth, with 3,393 locations in 109,781 square miles, producing a density of 30.91 sites per 1,000 square miles.
- Idaho is fifth, recording 2,350 locations within 82,643 square miles. This equates to 28.44 sites per 1,000 square miles.
- Arizona places sixth with 1,977 locations across 113,594 square miles, giving it a density of 17.40 per 1,000 square miles.
- Colorado ranks seventh. The state has 1,543 locations spread over 103,642 square miles, amounting to 14.89 sites per 1,000 square miles.
- Montana is eighth with 1,923 locations across 145,546 square miles, producing a density of 13.21 per 1,000 square miles.
- Alaska places ninth. Although it has 5,264 recorded gold locations, the second-highest total in the country, its vast land area of 570,641 square miles lowers its density to 9.22 sites per 1,000 square miles.
- Utah rounds out the top ten with 613 locations across 82,169 square miles, resulting in 7.46 sites per 1,000 square miles.
Wyatt McDonald, president of Coinfully, said: “At the end of the day, everyone dreams of being able to find gold one way or another, or at least coming across something of value, even if it’s another precious metal. Both for businesses and for individuals, if you’re looking to ‘strike lucky’, then it really is worth investing more time in the top ten states.”
“All of them share similar geological landscapes and environments, ideal for these metals, and if you’re in a state that isn’t in the top ten, it’s still worth looking for environments within your state that are similar to those in the top ten.”
The USGS database catalogues known mineral occurrences, including historical prospecting sites, mines, and deposits. While the findings highlight where reported gold locations are most densely concentrated, actual prospecting success depends on access, regulations, land status, and geological knowledge.
Recent USGS mineral commodity summaries show that modern large-scale gold production remains concentrated in states such as Nevada and Alaska. However, this study focuses on occurrence density, which may be more relevant to individual prospectors than industrial-scale mining output.
