Point Location Description: Mineral occurrence at surface symbol (Map, GDIF322)
Location Method: Conversion from MDI
Access Description: The H.W. 123 Occurrence is located in lot 6, Concession IV, of Southworth Township, and is approximately 3 km southeast of Dinorwic, on mining location H.W. 123. The occurrence is 200 m north of a concession road, about 1 km east of its intersection with Highway 17, which is 2.3 km south of Dinorwic. A shallow 3 m x 4 m trench is situated on the edge of a brush covered area in a hay field. (OFR 5723, p.215)
There is no record of work done on mining location H.W. 123, however, the occurrence was stripped and trenched sometime in the past.

Aug 04, 2022 (Q Unknown) - The area around the H.W. 123 Occurrence is underlain by mafic, massive and pillowed metavolcanics intruded by gabbroic sills containing abundant magnetite. Intensely sheared and iron carbonatized mafic metavolcanics occur southwest of the occurrence where 0. Satterly (1943) mapped them as carbonate-chlorite schists. The H.W. 123 Occurrence consists of a 3.0 m-5.0 m wide quartz-diorite dike striking 130° and crosscutting a 12 m wide shear zone striking 040°. The shear is hosted by medium-grained, chloritized, intensely carbonatized, mafic metavolcanic flows. The metavolcanics contain minor amounts of disseminated pyrite, chalcopyrite and arsenopyrite. Narrow veinlets of iron carbonate commonly contain small blebs of chalcopyrite. The quartz-diorite dike is fine- to medium-grained, pink-gray, and variably foliated, containing variable amounts of iron carbonate and small xenoliths of the mafic metavolcanics. The dike is intruded by an irregular stockwork of quartz-iron carbonate veins. Arsenopyrite, pyrite, and chalcopyrite are finely disseminated throughout the quartz-diorite dike, but are not associated with the quartz-carbonate veins. Arsenopyrite is commonly massive, comprising <5-50% of the rocks. The best assay from grab samples taken from the dike was 0.05 ounce gold per ton. A grab sample from the sheared and altered mafic metavolcanics assayed 0.05 ounce gold per ton and 0.42 ounce silver per ton. (OFR 5723, p. 215)
