Jul 22, 2008 (D Draper) - The sulphide mineralization occurs within strongly carbonatized, sericitized and locally silicified mafic volcanics. These zones of strong alteration occur adjacent to and within a distinct, pillowed variolitic mafic volcanic horizon. Volcanic units strike east-west and dip at 35-40 deg to the north. Tops determined primarily from graded bedding in sediments face south. Local shearing is present along flow contacts and within graphitic argillite at the mafic volcanic-sediment contact zone.

Jul 22, 2008 (D Draper) - Hole M13-13 intersected a series of pillowed mafic volcanics, massive leucoxene-bearing mafics, a thin basaltic komatiite in the upper portion of the drill hole, graphitic argillite and turbidite type sediments. A thin, grey quartz-feldspar porphyry sill intrudes the graphitic argillite unit. A gold value of 1.96 g/t over 1.1 metres was returned from a distinct, pillowed variolitic mafic volcanic. No zones of arsenopyrite-bearing fractures or arsenopyrite bearing quartz veins were noted in this drill hole. Hole M13-14 (collared 165m SE of M13-13) intersected an altered massive mafic horizon from 162.0 to 165.1 metres. This unit was strongly carbonatized and sericitized and weakly chloritic. The unit carried from 2 to 8% fine pyrite, minor pyrrhotite and 3-5% irregular quartz stringers. One anomalous gold value of 500 ppb over 1.5m was returned. This altered unit occurs immediately to the south of the distinct pillowed variolitic mafic volcanic. (T-3389)
