Dec 07, 2005 (K R Kettles) - The northern half of the Wilmar property is underlain by altered mafic flows, whereas the southern half is underlain by felsic metavolcanic flows and flow breccias. The units strike about N65 degs E and dip steeply south. On the basis of pillow packing stratigraphic tops are to the south. The Wilmar mineralized zones are found at or close to the contact between a silicified, felsic volcanic breccia and talc-chlorite-carbonate schist. The contact is thought to be a major fault zone. Rolls in the contact between the two rock sequences have been found to be an important guide to ore. Diorite, lamprophyre and diabase dikes/sills are present in all parts of the sequence.

Dec 07, 2005 (K R Kettles) - In the porphyry prospect a quartz-feldpsar porphyry dike over 168 m long in strike contains mineralized veins. The body is 10 to 15 m wide.

Dec 07, 2005 (K R Kettles) - A quartz-feldpspar porphyry dike, striking N82 degs E, was traced for a length of 167.75 m. The dike ranges in width from about 10 to 15 m. Irregular blocky fractures and joints contain short, narrow stringers of quartz and tourmaline as much as 12 cm in width. Along some of the joints, there are smaller stringers of quartz and carbonate from which gold values have been reported. Small amounts of pyrite, pyrrhotite, and chalcopyrite have been observed. This occurrence is very similar to the Wilmar West Granodiorite Zone, and is probably a subparallel structure.Two samples taken from the south side of the dike yielded assays of 0.445 and 0.590 opt Au. Sixteen other samples returned much lower values, averaging 0.012 opt Au.
Dec 07, 2005 (K R Kettles) - The country rocks have been silicified and carbonatized.
