Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some examples of what is mined. Why mine? Mining is a money making business. Most mined products are exported, hence you will need to obtain an export license. Look into that too. If you don’t intend to drill directly. the best way to get a good start in the industry is to contact the mining companies and ask for problems they face and what you can do about them.
