The high grade of historic production from shoots (15 g/t gold) makes this area an important target for exploration, to trace the depth continuity of the known ore shoots and to locate new ore shoots. All the ore shoots discovered in the Ramagiri Goldfield by the old miners, including the recent BGML operations, were below the ancient workings.

Extract copper and gold from low-grade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance, approximately 15-20 per cent of the world’s current gold production involves refractory ores that must be pre-treated prior to downstream recovery by cyanidation.
Gold ores are classified “free-milling” and “refractory” based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an appropriate ...

Aug 18, 2020 Currently, the New Consort Mine produces approximately 12Koz of gold per year. A Significant Breakthrough: High Values of Gold in Grams Per Tonne (G/t) G/t is the universal measure of the concentration of a precious metal found in an ore deposit and measured on a scale of gold in grams per tonne. Certain ore samples show grades over 300g/t.

The grade of mined, raw gold ore is measured in grams of gold per tonne of ore. High grade gold ore contains more gold per tonne; this means that more gold is obtained from every tonne mined. This greatly increases the profitability of a mine. Indeed, the high cost of processing extremely low grade ore may actually make mining financially unfeasible.
0–5.0 g/t gold is low grade; 5.0–8.0 g/t gold is average grade; Over 8.0 g/t gold is high grade; Gold measured in ounces per tonne is “bonanza” grade. Silver.
