Point Location Description: Precise
Location Method: Conversion from MDI
Access Description: The property is accessible by an overgrown trail which branches west and then south from a north-south bush road. The property is immediately south of the Van Horne Township line.
1913: Shaft was sunk to 40 ft. Vein reported to be mineralized with pyrite, chalcopyrite, galena, and sphalerite. 1917: Shaft was sunk to 60 ft. and two mill tests of the ore were made in 1913 and 1914. 1980: Acquired by H. Hodge. 1981-1983: Van Horne Gold Exploration Incorporated conducted geological mapping, sampling, and geophysical surveys over the property. 1987: Van Horne Gold Exploration Incorporated diamond drilled one 296 ft. hole beneath the shaft.

Jun 25, 2010 (J Bongfelt) - The S.V. 372 Occurrence consists of a deep shaft and 5 trenches (west of the shaft) sunk on a 0.3-0.9 m wide, linear shear zone striking 080º and hosting narrow discontinuous quartz-iron carbonate veins containing <1-2% pyrite and minor hematite. The host rock consists of medium- to fine-grained, gray-green, chloritic, massive, intermediate metavolcanic flows. The sheared wall rock is intensely sericitic, variably pyritic (1-5%), rusty, chloritic, and carbonatized (calcite) with minor iron carbonate. (OFR5723, p.288)

Jun 25, 2010 (J Bongfelt) - Two grab samples of the sericitic wall rock, taken by the author, that carried 1-2% pyrite assayed 460 ppb gold and 1820 ppb gold. Grab samples from the trenches and dump taken by Van Horne Gold Exploration Incorporated assayed 0.04, 0.18, and 0.02 ounce gold per ton. Van Horne Gold Exploration also diamond drilled one hole beneath the shaft, but intersected minimal amounts of quartz veins with no gold assays. (OFR5723, p.288) Grab sample, taken by J.R. Parker, found in centre of shear in largest of trenches (east end of trench), west of shaft. Assayed 1820 ppb Au (Kenora Property Visit File 52F/10NW00025)
