Aug 17, 2017 (A Wilson) - Conglomerate, with minor feldspathic quartzite and arkose, overlies the metavolcanics here. Two calcite veins have been reported in the adit. The adit vein strikes N40E and dips 78N and is reportedly up to 18 inches wide. The property lies immediately adjacent to the Maiden’s Lake Fault. Narrow veins of calcite occupy multiple shear zones within mafic to intermediate metavolcanics. The metavolcanics are described as slightly carbonatized and chloritized. The shear zones and veins range from 0.5 to 1.5 ft. in width. Narrow veins of calcite occupy multiple shear zones within mafic to intermediate metavolcanics.

Aug 17, 2017 (A Wilson) - It is possible that some cobalt or silver bearing veins could have been obliterated by the large, apparently barren carbonate breccia veins. (The breccia veins did not carry anomalous Co in the surface exposures.) It is also possible that some minor silver or cobalt values could have been missed in the sampling. Sections of lost core totaling 2.2 m are reported between 84m and 96m and additional lost core of l .2m near the bottom of the hole. No sludge samples were taken and some significant vein material could therefore have been lost or ground in these sections. However, as no anomalous Ag or Co, at all, was detected in any of the sampling, it seems likely that nothing significant was actually intersected. Two calcite veins have been reported on the adit. The one along the adit strikes N40ºE and dips 78°N with a reported width of 45 centimeters. According to a personal communication from Mr. de Camps to R. Thomson, it was reported to contain 0.48 and 0.42 % cobalt from a vein material near the end of the adit. A second vein found in the adit strikes across the adit with a bearing of N75CVV. This vein was intersected by one of the drill holes put down by G.W. Miller, who reported that it contains cobalt. The mineralization is finely disseminated within brecciated calcite stringers. Typical assays from the sheared veins include: 0.01% Co, tr. Ag over 1.5 ft., 0.76 oz. Ag over 0.5 ft. and 0.38 oz./t Ag over 2 ft.
