2017-7-20 Media competency is marginal and the possibility for “critical size” buildup exists; however, ore structure is such that semi-autogenous grinding appears to be a good possibility and pilot plant testing of semi-autogenous grinding is warranted. Further testing is not warranted. Conventional crushing and grinding
