Lithology

Lithology Comments

Jun 13, 2007 (D Draper) - Property geology consists of a mafic intrusive hanging wall to the south, followed by felsic volcanics, then a mafic volcanic footwall to the north (T-5190) Hole HM00-38 contained typical lithologies for this occurrence, with zones of massive sulphide up to 1.25m in downhole length alternating with felsic volcanic units from between an uphole contact at 151.5m with a mafic intrusive and a downhole contact at 160.65m with a mafic fragmental. (T-4997)

Mineralization

Mineralization Comments

Jun 13, 2007 (D Draper) - Minor sulphides are disseminated in the hanging wall and semi- to massive sulphides are located at the footwall contact. Economic and sub-economic grades of Cu-Zn have been traced for 250m of strike and 150m of vertical extent. (T-5190) 1996 discovery hole R44-11 returned assays of 4.26% Zn, 2.17% Cu, 51ppm Ag (271ppb Au) over 0.5m @ 116.3m and 11.92% Zn, 1.92% Cu, 42.5ppm Ag over 0.5m @ 118m from a felsic volcanic unit containing bands of massive sulphide. Elevated, but lower, values of Cu and Zn were also obtained in hole R44-14, which was drilled 175m grid south of R44-11. (T-3189) Hole HM98-19, drilled 100m SE of R44-11 (and 150m NE of HM00-38), intersected 8.3m of mafic volcanics (or perhaps altered felsic volcanic per note in log) containing massive sulphide units which returned an average of 7.12% Zn, 3820ppm Cu and 477ppb Au. This section included a 2m zone which averaged 19.03% Zn, 8950ppm Cu, 5675ppm Pb, 44.3 g/t Ag and 763ppb Au. (T-4420) In hole HM00-38 (160m S of R44-11), the 9.15m zone from 151.5m to 160.7m averaged 4.17% Zn, with the highest assay for the hole being obtained from a 0.4m sample of massive sphalerite with minor pyrite and chalcopyrite at 153.4m (19.6% Zn). Other occurrence-level assays from this hole: --10.5% Zn, 13.56% Pb, 72.2 g/t Ag over 0.1m at 47.3m in a felsic pyroclastic; --6.06% Zn, 6260 ppm Cu over 0.25m at 132.6m and 1.79% Zn over 0.7m at 134.9m in felsic volcanics; --8640ppm Zn over 0.6m at 181.2m in a mafic fragmental. Significant assays were also obtained from 5 other drillholes within 200m of HM00-38: --PAL-HM99-35: 17.32% Zn, 4.26% Cu, 1.01% Pb, 54 g/t Ag over 2m --PAL-HM99-34: 8960ppm Zn over 1m --HM00-40: 1.7% Zn over 2m --HM00-41: 5.4% Zn over 3m --MH00-42: 1.38% Zn, 3043ppm Cu over 1.8m (T-4997)
