Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The majority of the prospect is underlain by sequences of carbonatized mafic volcanic flows. Generally, the formations strike east-west and dip steeply to the south. Feldspar porphyry dikes have been observed, but are uncommon. The flows are fine to medium grained and green in colour. Generally, they are massive to weakly foliated and only locally show strong shearing. pillowed flows were noted, with tops to the north. The flows have been variably carbonatized and silicified. Some of the feldspar porphyry dikes contain barren ladder quartz veins. The gold mineralization is possibly associated with a postulated E-W-trending fault. DEPOSIT DESCRIPTION: Aurferous quartz-carbonate injections occur as irregular veins and blebs with thicknesses of 3 to 20 cm. Strike length of these zones rarely exceeds 2 m. Quartz veins, up to 50 cm. thick were noted in drill logs, snd contained values of gold. GEOPHYSICAL DATA: Both EM systems (H.L.E.M. and VLF) located strong anomalies over the fault zone. Good magnetic correlation is present. Other conductors located were either weak or explained by graphite and/or pyrite mineralization.

Dec 07, 2005 (K R Kettles) - One sample from surface mapping returned an assay of 0.01 oz/ton (0.343 g/tonne)Au. Several assays from the drill hole were valued at 0.01 oz/ton (0.343 g/tonne)Au. over .60 m to ,90 m.
Dec 07, 2005 (K R Kettles) - Varying intensities of carbonatization and silicification has occurred in the flows, along with a local, weak, epidote alteration.
