Province: Superior
Geological Age: Precambrian
Feb 14, 2011 (J Bongfelt) - The occurrence is situated within a fine- to medium-grained gabbro/diorite stock, at its northern contact with intermediate to felsic autoclastic flows of the Lower Wabigoon Volcanics. (OFR5723, p.279)
Feb 14, 2011 (J Bongfelt) - The R. 544 Occurrence consists of a shaft, or very deep test pit, about 12 m deep, a rock dump, and numerous shallow test pits sunk on intensely altered, fine-grained diorite which has been sheared (065º ), sericitized, and carbonatized. Numerous en echelon, northwest-trending (136º), tension fractures within the shear zone host pyritic [<1-3%], hematite, quartz veins containing iron carbonate and tourmaline. The altered wall rock contains up to 5% disseminated pyrite. (OFR5723, p.279)

Feb 14, 2011 (J Bongfelt) - A grab sample of altered, pyritic, diorite containing quartz veinlets, taken by the author from the dump, assayed 2950 ppb gold, while a sample of altered, pyritic, diorite assayed 1180 ppb gold. Two samples of quartz vein material taken from the dump assayed 0.41 ounce gold per ton, and 1430 ppb gold. A grab sample from a quartz vein, in the outcrop east of the shaft, assayed 10 ppb gold.
