The gold and copper results of the 2005 soil geochemical survey are not as high as those of the 2003 soil samples. It is assumed that the higher gold and copper values obtained in 2003 are the result of a chemical or physical enrichment of gold immediately above the bedrock surface.

Mapping was conducted at a scale of 1:10,000 in the area of the Serten-Hutel occurrence. Sixty rock chip grab samples were taken during the mapping program; most from the Serten-Hutel area and a few elsewhere on the property. A soil geochemical survey at a scale of 1:2000 was conducted in the same area. A total of 388 soil samples were taken. Rocks mapped on the property in July include greenstones of amphibolite facies, primarily orthoschists. Migmatized amphibolite-gabbros, granite-gneisses, tonalites, granites, granodiorites, andesites and basalts have also been identified and mapped. A variety of felsic dykes ranging from aplitic to pegmatic (texture) have also been identified. A variety of felsic dykes ranging from aplitic to pegmatic (texture) have also been identified. Chlorite and epidote-rich alteration is pervasive. The general foliation on the property is northerly with a moderately to steeply eastward to no rtheastward dip. Much of the property is covered by Quaternary sediments. Quartz veinlets, usually containing tourmaline, muscovite and sericite are common and tend to parallel the general rock fabric. Sulphide and iron-enrichment is common and usually parallels schistosity. Narrow quartz-hematite veins and veinlets have also been mapped. One such vein has been mapped along a strike length of about 150 m and reaches widths of up to 4.2 m. Another vein is about 35 m long and up to 6 m wide; it is more of a lense than a vein. A higher-than- usual concentration of quartz veins and veinlets is present within a few meters of these larger veins/lenses. The wall rocks are increasingly limonitichematitic closer to the quartz veins and veinlets. Sparse disseminated pyrite (and iron oxides after pyrite) is ubiquitous within the quartz. News Updates
