Aug 11, 2017 (A Wilson) - The Johnson Lake area returned several significant individual gold values from grab samples ranging from 0.51 g/t up to 3.83 g/t, 4.53g/t, 6.24 g/t, 9.14 g/t, 11.64 g/t, 12.91 g/t, 16.08 g/t, 49.75 g/t and 112.29 g/t gold. Gold mineralization, occurring across an area of approximately 800 metres by 600 metres, is directly associated with narrow gossanous fractures, up to several centimetres wide, cutting Proterozoic sediments interpreted to be near the unconformity with Archean rocks, and has associated anomalous copper, silver and iron oxide mineralization. The program also tested a target on the Rib Lake Property to the south of the Brett Boulder, and the soil geochemical survey was conducted on the Rib Lake claims. The LGP was developed following the discovery by Temex in late 2003 of a block of rock, known as the Brett Boulder and that assayed 6,222 g/t gold, with spectacular visible gold within narrow calcite veins hosted within mafic intrusive rock.
