The Ophir mine was first discovered in 1891 by Wlliam Moor, a local farmer, who owned the ground where the mine is situated today. It first operated in 1892 with ore processed through a 20-stamp mill powered by steam boilers and a 75 hp engine. Mill feed was trammed down from the adit entrance by gravity. The stoping consisted of an irregular, flat-lying (45) open-cut section, a winze near the centre and two shafts at either end of the workings. Old Bureau of Mine Reports indicate that production between 1892 and 1895 was in two lots, a 5170 pound bulk sample sent to the U.S. which produced 9.7 ounces of gold and a local production of 1002 ounces from 4865 tons of material. The bulk sample also produced 6.15 ounces of silver. From 1900 to 1902 the mine was owned by a Toronto Syndicate and known as the Ophir Mine. It produced 190 ounces of gold from 924 tons of material reportedly taken from the Fissure Vein. This would indicate a grade of 0.206 ounces per ton in gold. From 1909 to 1911, the Havilah Gold Mining Company produced 180 ounces of gold from roughly 800 tons which would grade 0.266 oz. per ton. In 1921, Kirk Gold Mines Ltd. took over the property and extended the workings which included limited cross-cutting and drifting along the main Fissure Vein on two levels, the Shaft Collar Adit and the 85 foot level. The Shaft Collar Adit was extended into the cliff face as an open cut to follow the vein eastward. The 85 foot level had 290 feet of drifting and 135 feet of cross-cutting work and the two were connected by two raises as sketched in Fig. 3 by Ludwig(1984). First reports indicate that the western shaft was 6 X 8 feet and went to a depth of 78 feet and was later extended to a maximum depth of 105 feet. The eastern shaft or raise was connected to the 85 foot level. There were no reports of any production during this period of time. In 1952, several vertical holes were drilled on Main Zone but logs and information are not available.

Dec 07, 2005 (P Beach) - Mississagi quartzite has been intruded by diabase. The main vein is within the diabase, strikes N75 E and dips 80 degrees south. It has been traced for a distance of 1,300 feet and varies in width from 7 feet to 1.5 feet. Quartz and carbonate are the main constituents of the vein with streaks of chlorite and small amounts of chalcopyrite, pyrite and native gold. ( ODM 1971 MRC 13 P 18).

Notes: The main showing consists of several auriferous quartz vein systems in a host of Nipissing diabase and appear to be structurally related to the east-west shear or faulting. The main Fissure or Ophir Vein strikes west south-west at 255 degrees and dips steeply at 80 degrees to the south with several small 'house-tail' spurs (Chimney Vein) coming off the main shear at approximately 45 degrees to the north. The main fissure vein was traced on surface for 175 feet over a large promitory of diabase. At the east-west ends, the zone is covered by overburden. Its width pinches and swells from 18 inches to 7 feet in width although in the adit, the vein has been observed to be 17 feet wide. Much of the vein material is a mixture of quartz vein and chlorite schist sandwiched by diabase. In the 'Chimney' zone was only 450 feet long as its lateral extent had been eroded away by glaciation.
