You non treasure hunters will never understand...Locating the gold is the easy part....Determining if it is going to be a lode claim or a placer claim is very important. Determining how the operation is to be run takes a lot of studying of local , state and federal laws... Access is also very important as tons of equipment and supplies will have to be brought in.
If you are filing a Placer claim it is simple to get enough partners to claim 100’s of acres if you can trust them but many areas do not allow open pit mining. With a lode claim it is much harder as there are regulations on withes and distance that you can claim....
Any way you look at it there will be millions of dollars invested before dig your first ounce of gold...Art
