What you are proposing is doable, but your question is kind of generic, it's like "I want a drink". A drink of what? Your location matters. A gold mine in Iowa makes no sense, but one in Georgia does. Shipwrecks? Buried hoards? I'd suggest you decide upfront what you want to go after and you will have to have a rock solid plan in writing before anyone will invest in it. Partners can be problematic, employees, not as much. It's a lot to consider. With a few notable exceptions, those guys make the news, most "treasure" is accidentally found. Like most of the Roman and Celtic hoards in the UK and some of the washed up shipwreck items in the US. The biggest gold nugget found in North Carolina was found outside somebody's house. The owner used it as a door stop, until they finally took it to have an expert look at it. Your will need an enormous amount of time and an even larger amount of money to hire people and look for treasure. I'm a realist, and have found two hoards and other good stuff by planning and being at the right place BEFORE anyone else got there. It has been a ton of work also.
