Briggs Mine
BA2. Location/Access:(35o 57.105’N, 117o 12.187’W) The Briggs mine is 7.7 miles south of Ballarat on a level, winding but good surfaced road maintained by the mining company.
Best Time: Afternoon, all year.
Geology: The Briggs Mine is a newly active gold mine. The company claimed that there are 21.4 million tons of mineable ore and 509,000 ounces of recoverable gold at an average grade of 0.03 ounces per ton. As of 2005, they are actively mining and heap-leach cyanide processing this ore. The ore is found within a metamorphic complex dated at 1.72Ga that is composed of a dark amphibolite gneiss and a light meta-granodiorite. This has been intruded by a Mesozoic quartz monzonite (Canyon Resources, 1994).
