Pablo… I have worked with mines from turquoise to gold; and my “sense” is not very supportive of your dream. All mining requires a tremendous amount of initial capital investment… a single earth mover is easily over $500,000 USA… let alone buildings,processing equipment, people & payrolls, and buyers and markets. And there are always unexpected expenses in 6+ figure range. I thought that your questions about “legal costs and permits” was too minor and seemed too far off the mark of what it will really take to open a successful mining operation. However, if you are a real mover and shaker, know how to get investors and partners, and are a terrific manager and highly outgoing… more power to you, and I hope you can realize your dream. Good luck.
