Point Location Description: Diamond drill hole
Location Method: Field Visit
Access Description: Access to the property is by gravel road at the Portelance property, 0.2 km north of the bridge in Kenogami. The road goes east for 0.9 km to the pipeline. The showing, as now exposed, is 1.4 kilometres north. The original drill holes are approximately 200 m to the south along the pipeline and buried. The pipeline is passable by truck. The UTM location for the new outcrop is 559256E 5329357N of the same vein system of the original Hecmac Syndicate.
In 1939 and 1940, Sylvanite Gold Mines, Limited completed an extensive exploration program on the Tremblay Claim immediately to the south of the pit on the McCombe property. Large trenches in the overburden were excaved (totalling over 160 m inlength) and extesively sampled. Two holes, totalling 152 m were diamond drilled. Veins trended at 330 degrees with assays to 2.76 ounce Au per ton. Assays were erratic. The original showing had ore grade values across 3 feet for a length of 25 feet. Assay results of the 2 drill holes were diassapointing. In 1959, the Hecmac Syndicate optioned claims from Pepin along the pipeline. Four holes, totalling 119 m, were diamond drilled under the pipeline to intersect a eight foot wide quartz vein system striking north to northeast. Reported grab assays are to about 0.5 ounce Au per ton but the best drill result was 0.1 ounce Au per ton over 2.3 feet (see also KL-1550). The following was accomplished by D.G. Sirola and Norcana and Orcana Resources, who optioned the property from Sirola, between 1978 and 1985 in assessment file KL-2512. In 1981, Norcana Resources Limited completed a VLF-Em and Magnetometer survey over thirteen claims. In 1983, Orcana Resources Limited mapped the property and completed a 34-hole overburden drill program totalling 70 m of drilling.

Dec 07, 2005 (D Guidon) - Older work tested narrow quartz veins within mafic Mg-tholeiitic volcanic rocks of the Kinojevis South assembalge, some of which are oriented at 330 degrees like the stratigraphy. One such vein or vein system appears to trend along the pipeline. This was tested by the Grenfell Exploration Syndicate and sampled by McCombe near this showing. Property descriptions by Archibald (KL-2512) suggest that shear zones trend approximately 300 degrees. Shear zones have been noted at this trend at the Four Nations property to the southeast.

Dec 07, 2005 (D Guidon) - The rocks are mafic volcanic, probably Mg tholeiites. They vary from very coarse grained flows with gabbroic textures, to massive, to pillowed to porphyritic. Strike is generally 330 degrees. Minor carbonate and leucoxene alteration exists in the relatively fresh rocks. Older work tested narrow quartz veins, some of which are oriented at 330 degrees like the stratigraphy. One such vein or vein system appears to trend along the pipeline. This was tested by the Hecmac and later sampled by McCombe near his float showing 200 m northwest along the pipeline.

Dec 07, 2005 (D Guidon) - At 5329357N 559256E the pipeline road goes up a hill. The pipleline goes around the hill/outcrop on the east side. Follow the outcrop edge along the side of the pipeline. Narrow quartz veins are exposed along the fractured edge of the outcrop and parallel the pipeline. These are reported to be auriferous by McCombe. The veins are mainly quartz with minor silicification and pyritization of the surrounding basalt.

Notes: Property was visited August 29, 1995, September 19, 1995 and May 29, 1996. This particular showing was only one of many visited. Little emphasis was placed on this on because: narrow quartz vein; low gold values; on the pipeline right-of-way; poor exposure ; zone parallels stratigraphy in a northerly direction; other zones are in a more favourable easterly direction and display alteration and pyritization. The original Hecmac discovery was on a vein system up to 8 feet wide with grab samples to 0.5 ounce Au per ton. The best drill hole assay was 0.1 ounce Au per ton over 2.3 feet. Assays by McCombe are reported to be less than 0.1 ounce per ton Au.
