Even with the decades of mining and exploration, much of the Comstock is still underdeveloped and its potential not fully tapped.
It’s not easy to figure out what is best without testing, and so a certain level of confusion has developed about how small the ore ought to be crushed.
Fortunately, there are products on the market that can address these problems and make a small-scale mining operation feasible.
They tend to be big, coming in large to extremely large sizes. They can also be amazingly rich and produce huge amounts of very high-grade ore.
Since we know that the secret to breaking rock is applying force from the inside out (putting tension on the rock), we will be looking at ways we can generate force using human and machine power.
