Exploration History

1915: Hopkins (ODM) - reported that on the Dunlap (sic) claim, a 20 foot deep pit was excavated on a 7 foot wide quartz- arsenopyrite vein by unknown persons, and reported that samples from the area yielded low gold values. 1919: Knight et al. - reported that the vein also contained pyrite, a little gold, and that low gold values were also present in pyritic, rusty weathering basalt where hosting quartz-calcite stringers. 1922: Hopkins reported that quartz-pyrite-arsenopyrite vein systems were typical of the area, occurring on both the Dunlop and Mayot (Lucky Ben Gold Mines Ltd.) properties. 1936: Kindle (1936) noted this occurrence. 1949: Satterly and Armstrong mapped the property. These authors reported the 7 foot wide vein to consist of multiple quartz veins, none of which is wider than about 12 inches and that the vein system strikes 070º, dips south 80º and is exposed discontinuously along about 100 feet. The presence of sparse sulphide mineralization, including chalcopyrite, in dump samples was noted by these authors.

Geology Comments

Feb 12, 2016 (R Degagne) - The occurrence is within a few tens of metres of the interpreted location of the Painkiller Lake Fault, a southeast striking structure which coincides along part of its length with the southwest shore of Painkiller Lake. Johnstone indicates that the Painkiller Lake Fault crosscuts stratigraphy along much of its length and that information compiled by him suggests that the fault is a steeply (about 80º) north dipping structure across which significant (about 800 m) of apparent dextral horizontal displacement has occurred. Johnstone also demonstrates that the Painkiller Lake Fault is younger and of a different character that other major southeast striking faults in the area.

Lithology

Lithology Comments

Feb 12, 2016 (A Wilson) - On the Dunlap claim, there is a 7 ft. quartz-arsenopyrite vein, running east-west.

Feb 12, 2016 (R Degagne) - Geological mapping indicates that the occurrence area is underlain mainly by southeast striking, steeply dipping and north facing weakly metamorphosed (greenschist or lower metamorphic facies) mafic volcanic and volcaniclastic rocks of the (Archean) Stoughton-Roquemaure Group.

Mineralization

Mineralization Comments

Feb 12, 2016 (R Degagne) - Low gold tenors are reported to be associated with narrow (less than 1 foot in maximum width) quartz-pyrite-arsenopyrite-chalcopyrite veinlets occupying a zone up to about 7 feet widewhich strikes 070 and dips 80 degrees south. Although no specific gold assays for the occurrence are available, the presence of arsenopyrite suggests that the low gold values reported by these authors probably occurs in amounts greater than 0.01 ounce of gold per ton. Satterly and Armstrong reported that the mineralized vein system is hosted along at least part of its length by pillowed lavas and flow breccias.
