The report, which was produced by the engineering firm Tetra Tech (NASDAQ:TTEK) based in Golden, Colorado, reports a Preliminary Economic Assessment (PEA) including a resource calculation based on a total of 714 drill holes totaling 85,844 meters. The project is a joint venture with Mountain Boy Minerals Ltd. (TSXV:MTB) and includes 26 contiguous claims with a net area of 1255 Ha. Pinnacle owns 70% of the project with the option to earn a larger percentage.

Several different process routes were investigated for the recovery of the contained gold, including:-Flotation-Whole-ore cyanidation-Cyanidation of flotation concentratesRougher flotation results show the gold is very amenable to recovery into a bulk sulfide concentrate, and that gold recovery from the low-sulfur composite was about 94%.A locked-cycle test was conducted on the master composite in order to evaluate the effect of recycling the intermediate flotation products. This locked-cycle test resulted in 94.7% overall gold recovery into a fourth cleaner concentrat...
