…there are loads of different copper minerals, but a large number of them form first in the ground as chalcopyrite and then through the effects of weathering are changed into other minerals like malachite, cuprite and chrysocolla.
I (enjoy) Twain’s description of a gold mine, “A hole in the ground with a liar at the top.” Some humor here? You bet, but I’m sure he meant it to be a real eye opener as well.

Epithermal deposits form in the ground at shallow depths. They are popular with prospectors because can yield very rich deposits and they are widespread in the Western US.

Lately my mind has been involved with group 4 of the transition elements, namely titanium, zirconium, and hafnium. They all have similar chemical properties. Of greatest interest to economic geologists and miners is that these valuable elements often occur together in sands.
There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.
