Jul 31, 2007 (D Draper) - The occurrence is within Falconbridge's FL-A grid which is located within a band of felsic volcanics which trend north-south through the western half of Sheraton Township. Holes drilled by Cominco during the 1970's in the northeastern part of the grid area intersected felsic and graphitic tuffs. All of the rocks are cut by north-south and east northeast striking diabase dikes. (T-4870)

Jul 31, 2007 (D Draper) - Drillhole SHER52-01 significant assays: --Average of 0.34% (3400 g/t) Cu over 11.57m. This section was divided between: a sedimentary unit of very fine grained massive black graphitic argillite with frequent large to small clasts of semi-massive pyrite and lesser fracture controlled chalcopyrite from 117.83m to 120.4m; and a felsic volcanic unit of a fine grained massive dark grey pyrite-chalcopyrite-bearing to rich quartz-feldspar rhyolite fragmental from 120.4m to 129.4m. --The sedimentary unit also included a return of 293ppm Co over 1.36m at 117.83m. As well, an assay of 382ppm Co was obtained from a 1.5m sample at 135.50m from the felsic volcanic unit. --0.814% (8140 g/t) Cu over 1.50m @162.5m. This assay is from a section of the hole from 156.58m to 212.72m that is not described in detail in the submitted log. --322ppb Au over 1.5m @ 69.5m from a unit of dense, weakly chloritic and fuchsitic tourmaline-sulphide-bearing quartz vein swarm hosted within a strongly siliceous and sericitic moderately fractured quartz-feldspar-phyric intermediate lapilli tuff (T-4870) Hole SHER52-03 was collared 120m east of SHER52-01. Significant assays: --Average of 0.56% (5605 g/t) Cu over 2m @ 232.8m in felsic volcanics with cpy associated with calcite veinlets --377ppb Au over 1.6m @ 84m in intermediate metavolcanics with disseminated py (T-4989)
