A prospector's need includes an ASSAYER, which is a person who tests ore or metals to determine their composition and quality. They also need a PAN, which is a shallow container used for washing earth or gravel in order to separate out valuable minerals. A PICKAXE is also necessary, which is a tool with a sharp point at one end and a handle at the other, used for breaking up rocks and soil. Finally, a grubstake is a loan of money or supplies given to a prospector in exchange for a share of any profits made from a mining venture.
