Lithology

Lithology Comments

Feb 18, 2015 (A Wilson) - Cobalt Series sediments are not exposed at surface on the property but under a thin covering of diabase they occur in a small area in the northwest corner of the East claim. Insufficient information is available to define the position of the bottom contact of the Nipissing diabase with precision. On an old vertical section available to the writer this contact is shown on the Kerr Lake No.3 shaft, 9th (550-foot) level at 330 feet due south of the northeast corner of the West claim. In drill hole K-53 this contact was at 645 feet core length or 575 feet vertically below surface. Except for 80 feet upwards from the contact this hole is completely in hypersthene diabase. The diabase forms the host rock of the silver-cobalt bearing calcite veins. The Hargrave No. 3 Vein extends over a horizontal length of 400 ft. a small shoot of ore on the 375 ft level at the northern extension of the vein yielded 35,973 oz Ag. The Hargrave No. 1 vein extends over a horizontal length of 200 ft.

Mineralization

Mineralization Comments

Feb 18, 2015 (A Wilson) - The ore occurred exclusively in Nipissing diabase with the possible exception of a minor amount from below thecontact in the No.l Hargrave vein. The ends of the prolific ore shoot of the No.3 Kerr Lake vein extended only short distances into Hargrave ground – the north end into the East claim, the south end into the Westclaim. Several other veins are known on the property. Drill holes K-51 and 52 were drilled to intersect a vein exposed at surface in a pit 450 feet south and 950 feet west of the northeast corner of the West claim. Drill holes K-53 and 54 were drilled to intersect a cobalt-bearing vein exposed in a pit 900 feet south and 600 feet west of the northeast corner of the West claim. J.H. Price, in charge of the drilling reports that in K-53 a one-inch vein with cobalt mineralization was intersected at a core length of 632 feet, that is 13 feet above the bottom diabase contact.

Dec 06, 2022 (Q Unknown) - Underground access through Conisil shaft (186 m) and 2 cross cuts, new veins: #78 and #2, 275 m and 315 m resp. WSW of #3 shaft, expl'd, devel'd, #78 partly mined.
