The Yubileinoe Porphyry Gold–Copper Deposit (Western
Abstract In the Uralian Fold Belt, there are quite numerous and well-studied porphyry copper (±Mo) deposits corresponding to the traditional "diorite" (most) or "monzonite" (Talitsa, Verkhneuralskoe) models. Along with them, there are relatively small but gold-rich massifs of porphyric granitoids, including the large Yubileinoe porphyry …

Gold Ore Grades Explained | PhysicalGold
Open Pit Mining. This method is used for near-surface deposits and generally involves removing large amounts of overburden to access the ore. The average gold grade for open pit mines typically ranges from 1 to 4 grams per tonne (g/t). Lower-grade ores can be economically viable due to the large scale of operations.

Optimisation of gold recovery by selective gold flotation for copper
Copper sulphides are selectively floated from pyrite ores at high pH's in excess of 11. It is less clear how the free gold behaves under these conditions. In addition, for extra gold recovery, further collectors are added, such as the monothiophosphates, which are known to be selective gold collectors.
