A mining company will proceed with the cost of a feasibility study generally once it has proved continuity of its ore deposits confirmed by samplings and or drilling on a relatively detailed grid that allows for fairly precise determination of tonnage, density, mineral and metal content and is that part of the orebody that economic viability

The mine initially accesses the orebody using two sets of twin decline tunnels with mining by fully mechanised long hole stoping methods with paste backfill. Paste backfill allows for a high mining extraction ratio as mining can be completed next to backfilled stopes without leaving internal pillars.

Apr 10, 2018· Due to the historic underground mining that has taken place on the property in 2012 and 2013 and the exploration drift put in by Kerr in the summer of 2017 there is a reduced amount of development required to get the mine up to full production. several trade-offs were conducted as part of the pre-feasibility study. The results are
