So let’s dive in and see what I can do to convince you that this is the year you should be out staking your own claims.
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
