Exploration History

1898: The Grimsby Gold Mining Company sunk a shaft to 36 ft. 1911-1912: A 17 ft. shaft sunk by Mr. G. Gordon was purchased by the Dryden Mining Company who deepened the shaft to 70 ft. and conducted 100 ft. of stripping. 1913: No. 1 shaft sunk to 90 ft. and a No. 2 shaft sunk to 43 ft. The No. 2 shaft was described as being about 590 ft. east of the No. 1 shaft. 21 ft. and 18 ft. crosscuts and a 50 ft. drift were developed in the No. 1 shaft. 1917: Purchased by the Cleveland Mining Company. 1937: Purchased by Vanlas Gold Mining Limited. It was reported that $60,000 was spent on exploration on the property prior to 1937. 1938: Vanlas Gold Mining Limited conducted trenching, test-pitting, and sampling. 12 trenches were blasted across three mineralized zones. 1940: 500 ft. of diamond drilling conducted on the property. 1980-1983: Property in the vicinity of the Vanlas Prospect was acquired by Van Horne Gold Exploration Inc. who conducted geological mapping, geophysical surveys, and sampling. The Vanlas No. 1 shaft is situated on patented ground owned by the Town of Dryden. 1987: Van Horne Gold Exploration Inc. and Power Explorations Inc. carried out drilling at the Vanlas No. 1 shaft. The patented ground, where the No. 1 shaft is located, was optioned from the Town of Dryden by Van Horne Inc. and a 3000 m drill program was initiated to follow up on the previously drilled intersections. The company named the mineralized zone "the Kidd Zone". 1988: Van Horne Gold Exploration Inc./Power Explorations Inc. reported that the 1987 drill program had delineated a small mineralized zone of 100,000 tons with an average grade of 0.20 ounce gold per ton.

Geology

Province: Superior

Geological Age: Precambrian  

Geology Comments

Feb 14, 2011 (J Bongfelt) - The prospect is situated within intercalated intermediate to mafic metavolcanic flows and pyroclastics of the Lower Wabigoon Volcanics which are intruded by numerous felsic dikes and quartz veins. (OFR 5723, p.291)

Lithology Comments

Feb 14, 2011 (J Bongfelt) - The mineralized zone is a brittle-ductile tectonized vein array containing gold within quartz-ankerite-tourmaline veins with disseminated magnetite and pyrite. The host rocks are a pervasively ankeritized and sericitized felsic pyroclastic interbedded minor silicified and chloritized intermediate to mafic flows and coarse pyroclastics. Through-going sericitized ductile shears appear to define master faults within the deposit that are flanked by gold mineralized veins in adjacent brittle fracture zones. (Kenora AF 52F/10NW, BBB-1, p.29 of Compilation Report) (Kenora AF 52F/10NW, BBB-1, p.29 of Compilation Report) The Vanlas property consists of two shafts, with the No. 2 shaft located 365 m northeast of the No. l shaft, and about 365 m of continuous and extensive trenching extending west towards Pritchard Lake from the No. l shaft. The two shafts and trenches occur within a broad zone of moderate to intense carbonate alteration associated with east-trending shearing and fracturing which extends east from Pritchard Lake within intermediate and mafic metavolcanic rocks. Numerous, pyritic, quartz veins occur throughout the zone, as well as east-trending felsic dikes commonly containing variable amounts of disseminated pyrite and magnetite and hosting quartz veins. This zone includes the Glatz-Pritchard Lake Occurrence, situated immediately east of Pritchard Lake. (OFR5723, p.291)

Mineralization Comments

Feb 14, 2011 (J Bongfelt) - Significant values from the Kidd No.1 Zone include: 0.40 oz/t Au over 22.0 ft 0.23 oz/t Au over 12.3 ft 0.20 oz/t Au over 14.6 ft 0.22 oz/t Au over 7.2 ft. The best result from the Kidd No.2 Zone was: 0.31 oz/t Au over 4.2 ft Although the drilling appears to have defined at least one deposit, the Kidd No.1, drilling to the east and west also intersected significant values that suggest mineralization may be starting again in either direction, including: 0.17 oz/t Au over 3.9 ft - westernmost drill hole in the program 0.28 oz/t Au over 7.2 feet - easternmost drill hole in the program * Developed Prospects results: - 106,000 Tonnage @ grade 0.19 (oz. Au/ton); cut-off 0.05 (oz. Au/ton) - T.S. Joliffe (1989) (Kenora AF 52F/10NW, BBB-1, p.29-30 of Compilation Report) Shaft No. 1 Grab samples from quartz veins in the trenches assayed 1300 ppb gold and 3150 ppb gold. Grab samples of pyritic quartz vein material from the dump assayed 1110 ppb gold and 9700 ppb gold while a grab sample of the altered, pyretic [<1%] felsic dike assayed 450 ppb gold. Shaft No. 2 A grab sample taken by J.R. Parker from quartz vein material on the dump assayed 3730 ppb gold. A grab sample taken by J. R. Parker from the dump, of the magnetic, pyritic (2%) felsic dike, hosting some quartz veinlets assayed 1140 ppb gold. Sampling done by T.S. Joliffe of Van Horne Gold Exploration Inc., also indicates that anomalous gold mineralization occurs throughout the broad zone of carbonate alteration, fracturing, and shearing which encompasses the Vanlas shafts. * Developed Prospects results: 1988: Van Horne Gold Exploration Inc./Power Explorations Inc. reported that the 1987 drill program had delineated a small mineralized zone of 100,000 tons with an average grade of 0.20 ounce gold per ton. (OFR 5723, p.291-292)

Aug 02, 2022 (Q Unknown) - 1898: Quartz vein reported to give an average assay of 0.44 ounce gold per ton. 1987: Drilling at the Vanlas No. 1 shaft, conducted by Van Horne Gold Exploration Inc. and Power Explorations Inc., resulted in an intersection of 0.26 ounce gold per ton across 24.6 ft. including a smaller section of 0.71 ounce gold per ton across 8.7 ft. Drill intersections such as 0.23 ounce gold per ton across 43 ft., 0.33 ounce gold per ton across 7.9 ft., and 0.40 ounce gold per ton across 22 ft. were encountered during the summer drill program.
