This is a complex gold ore with oxide gold in a quartz vein with sulfide gold. The sulfide gold is too fine to see, it was probably hydrothermally deposited as a replacement for the iron and pyrites (dark holes) that reduced and oxidized to iron (staining the ore), leaving cavities for gold to enter with the water or steam. (My theory) Ore is from a California deposit. ...

Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface). Locating the richest gold bearing areas primarily involves research, planning, dedication and funds. In other words, those who study geological surveys, land formations, rock structures and gold prospecting history prior to prospecting may have a better chance of finding desired amounts of gold. (See ...

Ore types of oxidized gold ores have gold contents as high as 10 g/t and an agitated leaching process is a good and attractive alternative due to the leaching is high and consequently the gold extraction is high, typically more than 90%.

THE OLD GOLD MINE: Our local surfaces owners worked in the past, processing oxidized materials at surface gold veins. Several gold veins were discovered at that time giving information of what they had in the underlying layers. When they found sulfides, the recovery was not satisfactory so, they moved to new veins. The normal depth for that operation was about 2 or 3 metes, with exception for ...
