A single piece of gold ore generally has very little actual gold content Although a very rich ore may have some visible gold present the vast majority do not actually have any visible gold present and only crushing and processing of the ore will release the gold within to host materialProducing from this ore concentrate 233oz of gold per pound 66oz of Pd per pound makes what others that have a 401K or a retirement pension fund have Its sure a good time to have precious metals in the ground when all hell is raging above the ground
