Point Location Description: The Lost Mine is located on claims K.558506 and K.558598 in Con. I, Lot 6, Van Horne Twp.

Location Method: Conversion from MDI

Access Description: The Lost Mine is accessible from an overgrown bush road which extends east from the gravel road along which the Bonanza Mine is located. The gravel road branches south from the Wabigoon Lake Road. The overgrown bush road branches east where the gravel road terminates at a small beaver dam. Follow the bush road about 730 m and then walk 60 m west from the road to the No.! shaft at the Lost Mine. Walk another 215 m due west to the No.2 shaft at the Lost Mine. (OFR5723, p.236)

Exploration History

1904: A quartz vein containing 'a good deal of free gold' was stripped for 500 ft. 1910: Two shafts 298 ft. apart were sunk to depths of 22 ft. and 54 ft. 1917: Additional stripping completed between the two shafts. 1928: Purchased by Wabigoon Contact Bay Gold Mines Limited. 34 tons of ore tested in Chrome, New Jersey produced $182 worth of gold (about 8.0 ounces of gold). 1931: Minor development work reported. 1935: Purchased by Northern Mines Incorporated. 1980: Acquired by H. Hodge. 1981-1983: Van Horne Gold Exploration Incorporated conducted geological mapping, geophysical surveys, and sampling on the property. 1987: Van Horne Gold Exploration Incorporated diamond drilled two holes totalling 623 ft. beneath the No. 1 shaft. 1987: Norontex Exploration drilled a hole near the eastern shaft. 1998-1999: Wm. J. Sovereign, performed stripping, line cutting, pit cleaning and assaying of the Lost Mine area.

Geology

Province: Superior

Geological Age: Precambrian  

Geology Comments

Jun 25, 2010 (J Bongfelt) - The mine is situated within intercalated mafic metavolcanic flows and intermediate to mafic tuff-breccia of the tholeiitic to calc-alkaline Lower Wabigoon Volcanics. The metavolcanics are intruded by mafic and felsic dikes. (OFR5723, p.236)

Lithology

Lithology Comments

Jun 25, 2010 (J Bongfelt) - The two shafts at the Lost Mine are located along the steep southern edge of an extensive outcrop. The second shaft is about 215 m west of the first shaft, with large continuous trenches between them. Both shafts have been sunk on the same wide shear zone and felsic dike. (OFR5723, p.236) SHAFT NO. 1 The geology at the No.1 shaft consists of intermediate to mafic tuff-breccia intercalated with massive and brecciated flows intruded by narrow, mafic and felsic dikes. SHAFT NO. 2 The geology is identical at the No. 2 shaft, however, the felsic dike hosts the majority of quartz-tourmaline veins. (OFR5723, p.236)

Mineralization

Mineralization Comments

Jun 25, 2010 (J Bongfelt) - Historic values ranging up to 8 oz/T Au were reported from early work. OGS sampling in the 1980's obtained values ranging up to 7950 ppb Au. VHX took several samples and obtained values ranging from 0.10-0.18 oz/T Au. VHX completed one drill hole under the showing in 1987 with no reports of significant intersections. (Kenora AF 52F/10NW, BBB-1, 2007 Compilation Report, pg.37) * Occurrence results: - A grab sample, taken by J.R. Parker, from a quartz vein in a trench in sheared metavolcanics, about 4.6 m east of shaft No. l, assayed 1950 ppb gold. - A grab sample taken from a quartz vein in a trench within sheared metavolcanics, about 36.6 m west of the No. 2 shaft, assayed 7950 ppb gold. - A grab sample of quartz vein material and a sample of the pyritic dike was taken from a trench immediately east of the No. 2 shaft, assayed 100 ppb gold and 300 ppb gold respectively. - Assays from samples taken in one of the shafts, reported in the Daily Times Journal (April 26, 1910), ranged between 0.10 ounce gold per ton and 95 ounces gold per ton. - The property reportedly produced 8.0 ounces of gold from 34 tons of ore at an average grade of 0.26 ounce gold per ton (Mineral Deposit Files, Resident Geologist's Office, Kenora). - July, 1998: Wm. J. Sovereign obtained encouraging assay results of 17.76 g Au/ton (.518 Au oz/ton), and 12.55 g Au/ton (.366 Au oz/ton) - grab samples. (Kenora AF 52F/NW, SS-2, Sovereign, W.J.) * Prospect results: - Van Horne Gold Exploration Incorporated drilled two holes beneath the No. l shaft. One hole intersected two gold bearing sections assaying 0.14 ounce gold per ton across l ft. and 0.08 ounce gold per ton across 9 inches in felsic to intermediate tuff hosting quartz veins. (OFR5723, p.237)

Aug 03, 2022 (Q Unknown) - The Lost Mine was worked from 1904-28. Two shafts and several long trenches were established to expose quartz-tourmaline-chlorite-pyrite veins in felsic dykes within an east-west trending shear zone in altered mafic tuff. The Lost Mine, with its relatively high grade historic values, reproduced to a reasonable extent by limited sampling in the 1980s, has not been thoroughly tested, it appears to be part of a long fault structure that hosts the Bonanza, Drake, Lost, and possibly the Little Jumbo mines and should be thoroughly tested using modem exploration techniques (Kenora AF 52F/10NW, BBB-1, 2007 Compilation Report, pg.37)
