Point Location Description: inclined shaft
Location Method: AMIS Site Visit
Access Description: Proceed 5.5km east of the junction of Hwys 101 and 672 to Holt McDermott Mine. Continue 5.6km south on tailings road site.
1917: Gold (quartz vein material assaying as much as 1.9 ounce of gold per ton is reported) discovered by L.B. Howey, M.R. Howey, W.M. Cochenor, and D. Willans. G. Young and S. Cragg optioned the claim during the year (Hopkins 1918). 1918: A road from the Croesus Mine area (in Munro Township) was cleared to the discovery site. The discovery vein was pitted, trenched, and a 73 foot long inclined shaft was sunk. During shaft sinking, 'considerable' free gold was encountered in the quartz vein. 1919: The American Zinc Co. worked the claims. 1925: By this time, a contiguous 10 claim block was being explored by Lightning River Gold Mines Ltd.. 1933: Lightning River Gold Mines completed geological mapping. 1937: Lightning River Gold Mines properties were advertised as being for sale. 1944: By this time, Coin Lake Gold Mines Ltd. held claims in Holloway township. 1945: Coin Lake Gold Mines diamond drilled 14 holes. 1981: Canadian Nickel Co. Ltd. staked a large claim group in the Harker-Holloway Township area and, with Argentex Resources Exploration Corp. Ltd., completed magnetic and electromagnetic surveys over them. 1984: Coin Lake Gold Mines Ltd. was controlled by Wilanour Resources Ltd. which in turn was controlled by Camflo Mines Ltd. (Canadian Mines Handbook 1984-1985). The Canadian Nickel Co. properties were optioned by a joint venture group involving Discovery Mines Ltd. and Lenora Explorations Ltd.; Discovery Mines acted as operator. Discovery Mines/Lenora Explorations completed geophysical surveys, trenching, 18 DDH's (8,305 ft). 1985: Coin Lake Gold Mines was controlled by Wilanour Resources (which was controlled by Barrick Resources Corp.).
Province: Superior
Subprovince: Abitibi
Terrane: Wawa-Abitibi
Belt: Abitibi
Geological Age: Mesoarchean
Metamorphism Grade: Greenschist
Aug 01, 2016 (R Degagne) - Bedrock is the area consists of weakly metamorphosed (greenschist or lower metamorphic grade) east northeast striking, steeply south dipping, and south facing volcanic rocks and minor interflow sedimentary rocks of the (Archean) Kinojevis Group. The volcanic stratigraphy in the area forms a monoclinal south dipping and south facing succession, occupies part of the north limb of the east striking and east plunging Blake River Synclinorium. The occurrence is about 5 km south of the east striking Porcupine-Destor Fault Zone.

Aug 01, 2016 (R Degagne) - Bedrock near the shaft consists mainly of variably glacial drift covered 080 striking (as shown clearly by a geophysical survey of Holloway Township and south facing tholeiitic basalt and intercalated rhyolitic flows. Rhyolite horizons may be up to 250 feet thick, can be traced discontinuously on surface (and via their magnetic signatures) for as much as 8 km along strike, and are in the shaft area pink, fine grained, amygdaloidal, flow banded, and feldspar phyric. Locally, rhyolite may be fractured and host fracture controlled hematite. Intrusive bodies are absent from the shaft area. The quartz vein system on which the short (about 73 feet deep) inclined shaft was sunk is 110 striking, dips south at about 23 degrees, and crosscuts the east northeast striking and steeply dipping volcanic stratigraphy. The vein is reported to be hosted to the west by basalt and to the east by rhyolite. The vein is reported to have been explored discontinuously along about 175 feet of strike via trenches and pits. The inclined shaft is collared on the vein where it is hosted by basalt about 40 feet north of a basalt/rhyolite contact near the vein's western exposed end. Sinking the shaft revealed the discovery 'vein' to be narrow (locally as wide as 10-12 inches but in general averaging about 4 inches in width) and to have associated with it several parallel veinlets (generally less than 1 inch in width) with the overall form being that of a sheeted vein system confined to a 2-3 foot wide shear. Where the shear hosting the vein(s) crosscuts the basalt/rhyolite contact, about 4 feet of apparent reverse (dextral) offset has taken place.

Aug 01, 2016 (A Wilson) - Visible gold was seen in a number of specimens. A three-inch cross section of the vein assayed $16.30.
Aug 01, 2016 (R Degagne) - Quartz vein material where not fractured is reported to be coarse grained, white, and vitreous, but it may be 'granulated', grey, and host 'secondary' calcite, pyrite, and chlorite. These authors also noted sphalerite, galena, and plagioclase at the occurrences and that these minerals characteristically occur within brecciated vein material rather than in coarse grained unbrecciated intervein domains. In the main vein, both fine grained (visible) gold associated with pyrite and coarser grained (visible) gold occur in granular vein material. Near the vein(s) (and confined to the host shear?) the host rocks are schistose, carbonatized, and host calcite and chlorite veinlets. The vein is reported (assessment files) to pinch out rapidly at depth within rhyolite and along its strike to the east within rhyolite. Vein material is reported to carry only low gold tenors where hosted exclusively by rhyolite.

Notes: The quartz vein system on which the short (about 73 feet deep) inclined shaft was sunk is 110 striking, dips south at about 23 degrees, and crosscuts the east northeast striking and steeply dipping volcanic stratigraphy. The vein is reported to behosted to the west by basalt and to the east by rhyolite. The vein is reported to have been explored discontinuously alongabout 175 feet of strike via trenches and pits. The inclined shaft is collared on the vein where it is hosted by basaltabout 40 feet north of a basalt/rhyolite contact near the vein's western exposed end. Sinking the shaft revealed thediscovery vein to be narrow (locally as wide as 10-12 inches but in general averaging about 4 inches in width) and to have associated with it several parallel veinlets (generally less than 1 inch in width) with the overall form being that of asheeted vein system confined to a 2-3 foot wide shear. Where the shear hosting the vein(s) crosscuts the basalt/rhyolitecontact, about 4 feet of apparent reverse (dextral) offset has taken place. Channel sampling of the shaft is reported to have averaged about 1.93 ounces of gold per ton over an undisclosed length. West of the shaft, the vein was not followed west of 2 vertical slips striking 028.At various places in the rhyolitic horizon, considerable pyrite is associated with quartz veinlets.Where such material has been sampled in the shaft area, anomalous (as much as 0.38 ounce of gold per ton) gold assaysare reported. Although the rhyolite is reported to be fractured across at least 120 feet, most quartzstringers are reported to be confined to the northern rhyolite contact; a sample from the contact area yielded about 0.09 ounce of gold per ton.
