Two online resources, MineCache.com and GoldMapsOnline.com use public data including the U.S. Bureau of Land Management’s library of active and unclaimed gold mines. GoldMapsOnline.com is a fee-based map provider; users view mines in Google Earth by state, as explained on GoldMapsOnline.com.
MineCache.com also uses Google Earth and charges a fee for viewing maps. The service offers a seven-day free trial that clients use to research historical and current gold mines inside the borders of the United States. The data updates automatically each month and other resources include information for staking a claim after identifying an eligible location, as outlined on MineCache.com.
