The Bwlchgoch mine (so named from a Welsh word meaning “Red Mountain”) is located near the head of the South Fork of Lake Creek. A vein trending N. 80° E. has been developed through three levels. The Bwlchgoch is unlike the majority of the mines in the vicinity, in that the ventilation is very poor, and as it had not been in operation for more than a year at the time the writer made his visit, examination of all the workings proved impracticable. The country rock is gneiss, schist and pre-Cambrian quartz monzonite, and there is no indication of the presence of any quartz porphyry dikes.
The ore is a coarse, pyritiferous quartz, with which is associated a large amount of chlorite and talc, which has been developed by alteration of included wall rock. The pyrite is rather coarse, and in the ore now visible in the old stopes there appears to be no well-defined shoot.
