Access Description: A point 4.90 km south and 5.20 km west of the northeast corner of Thackeray Township.
circa 1920: Prospecting in the area led to the discovery of anomalous sulfide mineralization with associated anomalous gold tenors (Jensen 1978). 1950: Dominion Gulf Co. completed geological and magnetic surveys. 1965: International Bibis Tin Mines Ltd. completed HL electromagnetic and magnetic surveys, diamond drilled 3 holes totalling 1,052.8 feet, and reported a drilling intersection averaging 0.02 ounce of gold per ton. 1975: H. Jourdain completed a geological survey in the area. 1978: Amax Minerals Exploration completed a geological survey. Grab samples averaging as much as 0.09 ounce of gold per ton were reported. 1985: Cominco Ltd. completed a magnetic survey and stripped overburden. Vanstates Resources Ltd. completed a geological survey (The George Cross Newsletter, August 5, 1985). 1986- 1987: Cominco and Vanstates Resources completed magnetic, HL electromagnetic and IP electric surveys, and diamond drilled at least 26 holes totalling 3,775 m. Alteration and anomalous gold tenors intersected by this drilling were reported (The Northern Miner, November 24, 1986) to be 'nearly identical' to those at the American Barrick Resources Corp. Holt-McDermott Mine, in northwest Holloway Township. Core lengths of 4.8 feet and 4.44 feet averaging 0.14 and 0.22 ounce of gold per ton, respectively, were reported (The Northern Miner, November 24, 1986; The George Cross Newsletter, December 5, 1986).

Province: Superior
Geological Age: Archean
Metamorphism Grade: Greenschist
Dec 07, 2005 (C Salo) - Weakly metamorphosed (greenschist or lower metamorphic grade) subaqueously deposited basalt of the (Archean) Kinojevis Group which strikes east northeast, dips steeply south, faces south, and occupies part of the north limb of the Blake River Synclinorium (Johnstone and Steele 1989, Sutcliffe and Steele 1989, Jensen 1978, Jensen and Langford 1985) hosts narrow (20- 50 m in width) intercalated horizons of rhyolitic volcanic rocks. Intrusive bodies of syenite, granite, lamprophyre and diorite as dikes and irregularly shaped masses also occur in the area. Dike material in the area is reported to vary in composition from nearly pure feldspar through quartz-feldspar to types with marginal zones which are dioritic and amphibolitic in composition (assessment files, Resident Geologist's Office, Kirkland Lake). A recent geophysical survey of Thackeray Township (OGS 1984) failed to detect any anomalous bedrock conductors in the area.

Dec 07, 2005 (C Salo) - The rhyolitic horizon exposed by the Cominco trenches consists of varicolored (grey-mauve-liver colored-yellow-green) massive, flow banded, and amygdaloidal rhyolite.

Dec 07, 2005 (C Salo) - Background gold tenors in rhyolite are reported to be generally less than 50 ppb, although tenors as high as 230 ppb have been encountered Gold tenors in the altered variolitic basalt exposed in the central trench, however, may be as high as 0.21 ounce of gold per ton. Anomalous gold tenors associated with sulfide minerals in the area which were delineated in the past were evidently associated with quartz veins (Myles Johnson, pers. comm., 1985). Whittaker (1986) indicated that samples from the area contain both free gold and gold as inclusions on or within pyrite. In 1985, Whittaker described gold mineralization in the area as follows: 'Gold mineralization in west central Thackeray Township...is spatially related to flow banded, quartz-phyric rhyodacitic flows in a sequence of massive to variolitic tholeiitic flows of the Kinojevis Group (Jensen 1982). Alteration, including silicification, hematization, sericitization, and pyritization, has affected black, iron tholeiites overlying the felsic metavolcanics. Pervasive silicification has imparted a saccharoidal texture and conchoidal fracture to the mafic flows; hematization has produced a mottled purple-mauve color, and sericitization, a pale green-grey color. Potassic alteration, which is superimposed on pervasive silicification, is centred about intersecting hairline fractures filled with quartz veinlets. Fine to very fine grained pyrite is both disseminated in the rock and concentrated along fractures, and can form 5% to 7% of the altered mafic flows. The area is cut by several narrow, conformable shear zones, which post-date alteration. ' (Whittaker 1985, p.313) '.
Dec 07, 2005 (C Salo) - Silicified (as manifested by vein and veinlet development and quartz filled amygdules), hematized (as manifested by pervasive mauve to liver colored (hematitic) domains and as fracture controlled specularite development), sericitized, carbonatized (as penetrative Fe-dolomitization and fracture controlled white veinlet development), albitized (veinlet and amygdule controlled), and pyritized. Some fractures in rhyolite are surrounded by symmetric narrow halos of bleaching or and red alteration; Whittaker (1985) verified that at least some of this alteration is due to potassic metasomatism.
