Jun 11, 2010 (J Suma-Momoh) - The main shear zone can be traced for roughly 60 metres. Its strike is variable from 039 to 060 degrees with variable sub-vertical to 70 degree south dip. Subsidiary shears splay from the main shear. These also warp or curve and have overall trends ranging from 090 to 120 degrees. REF: Report by W.J. McGuinty (dated January, 1991), page xxv, in KL 2565.

Jun 11, 2010 (J Suma-Momoh) - The host rock for the Carbonate Zone is coarse andesite fragmental. REF: Report by W.J. McGuinty (dated January, 1991), second sentence on page xxiv; in KL 2565. Sampling for gold performed on this showing indicates gold concentrates preferentially in sulphide enriched rocks including sulphide rich quartz veins and sheared moderately altered andesites with disseminated pyrite in thin fractures. REF: Report by W.J. McGuinty (dated January, 1991), last paragraph of page xxv, in KL 2565.

Jun 11, 2010 (J Suma-Momoh) - The Carbonate Zone was sampled in two areas over a length of 250 feet and returned numerous low grade gold assays with the best high return of 0.223 oz/t gold. Fine-grained pyrite, molybdenite and Arsenopyrite are present throughout the zone which has also undergone various stages of Silicification. Report by Carl P. Forbes (dated January, 26, 1989), page 11 - 12, in KL 2565. Diamond Drill Hole BDN-89-1 of the Carbonate Pit Area returned up to 0.136 oz/t gold over 0.9 metres. REF: Map KL 2565-24, in KL 2565.
Jun 11, 2010 (J Suma-Momoh) - Alteration is predominantly carbonate and silica replacement varying in degree from partial carbonate replacement of host rock, leaving ghosted or deferentially altered fragments with most of the volcanic texture intact to strong carbonate alteration with silica influx creating a pseudo-breccia texture with no remnant volcanic texture. All strongly altered, carbonate and/or silica enriched rocks show a marked pseudo-breccia texture as well as greasy sericite-carbonate slip planes. Sulphide mineralization, mainly euhedral pyrite, is common in veins and on vein contacts and as disseminations in altered fragmentals which have undergone only moderate carbonate and/or silica replacement. Very little sulphide persists in highly altered material. REF: Report by W.J. McGuinty (dated January, 1991), page xxiv to xxv, in KL 2565.
