Point Location Description: Area of drilling
Location Method: Data Compilation
Access Description: The occurrence is located approximately 57.5 km northeast of the town of Terrace Bay (claim map G-596). The occurrence is located approximately 4.4 km north of a similar body of mineralization known as the Killala Lake occurrence. The Jackpine logging road which is part of the Dead Horse Creek road system accesses the area 1 km to the northwest of the occurrence. Access is also available by helicopter from the Marathon or Manitouwadge airports.
1954: Geophysical surveys (Airborne and SP) and diamond drilling (24 holes totalling 3830 m); Killala Lake Mines. This work was conducted in the Killala Lake area. Geological mapping and diamond drilling (5 holes totalling 475 m); Baseline Mines Ltd. This work was conducted in the Drainage Lake area. 1968: Diamond drilling (6 holes totalling 382.8 m); Maria Mining Corporation Ltd. This work was conducted in the Drainage Lake area. Ground geophysical (IP) and geochemical surveys; Newmont Mining Corporation. 1970-1975: The area was staked twice (by Jamex Explorations Ltd. and by Noranda Mines Ltd.) but no work was recorded. 1985: Airborne geophysical survey (VLF-EM, MAG); Noranda Exploration Company Ltd. 1986-1987: Linecutting, geological and geophysical surveys and sampling; Imperial Platinum Corporation. 1993: R. Komarechka carried out prospecting and sampling.

Dec 07, 2005 (D McKay) - Schnieders et al. (1996) describe the occurrences in the area (i.e.: the Sandspit-Papaver and the Killala Lake occurrences) as follows: The occurrences lie within a large body of gabbro of the Killala Lake, alkalic complex throughout which are found small amounts of disseminated pyrrhotite. A zone of massive to disseminated pyrrhotite, containing a little chalcopyrite, has been traced by drilling for a distance of 335 m on the west side and in close proximity to a north-trending fault.

Dec 07, 2005 (D McKay) - Schnieders et al. (1996) describe the mineralization as follows: The Sandspit-Papaver deposit consists of streaks and patches of massive pyrrhotite, with minor chalcopyrite, alternating with gabbro containing finely disseminated sulphides. The best widths and values occur where the fault swings locally to assume a strike of N30 degrees E. Coates (1970) states: The gabbro is particularly rich in magnetite, apatite, and pyrrhotite in certain layers. Small amounts of chalcopyrite are found in association with the pyrrhotite. The assay results in the drill logs (ODM File 4-24-370) indicate that the highest values obtained at the Popover occurrence were 0.32 percent copper and 0.07 percent nickel over 10 feet in Hole 4K, and best nickel value was 0.16 percent nickel over a 9-foot (3 m) length in the same hole 4K. Most of the assays were considerably lower.
