Access Description: The occurrences area located approximately 1.5 km northwest of Nagunagisic Lake, 40 km northwest of Schreiber. Access may be gained by aircraft or overland from the Gravel River, 4 km to the east.
1973: Two sulphide occurrences were discovered and test-pitted by N. Cox and D. Thorsteinson. 1990: The property was staked and prospected by R. Reukl and B. Michon. 1992: Prospecting and diamond drilling were carried out with assistance from an OPAP grant. Additional prospecting was conducted in the area. 1995: The occurrences are currently held by B. Michon and R. Reukl.

Dec 07, 2005 (B Nelson) - The Salamander Point showing is found on a rocky point on the north shore of a small lake approximately 1.3 km northwest of the northern tip of Nagunagisic Lake. Virtually the entire outcrop consists of a massive, 'bull white', rusty weathered, composite quartz vein. The vein attains a maximum exposed width of approximately 8 m. A small pit has been sunk on the vein. The vein consists of massive quartz and angular quartz fragments in a dark, siliceous matrix. Fine grained, feldspathic wallrock xenoliths up to 30 cm wide occur along the vein margins and are cut by reticulate quartz veinlets up to 2 cm wide. The granitoid wallrock is foliated near the vein margins and contains conspicuous, subhedral feldspars in a finer grained, mafic matrix. Fine grained, disseminated pyrite occurs throughout the vein. Chalcopyrite has preferentially developed in the coarser grained portions of the vein. Narrow, younger veins have developed cockscomb textures in drusy quartz. The vein strikes at about 040 degrees and appears to follow a narrow ravine that extends northeast towards the more northerly Burning Rock occurrence and continues across on the south side of the small lake.

Dec 07, 2005 (B Nelson) - Grab sampling of mineralized quartz vein breccia at the Salamander Point vein returned 0.946% Cu, and nil Au, Ag, Pb and Zn. *Reukl (1993) reported that 1992 diamond drilling intersected 2.58% Zn, 0.33% Pb, 0.04% Cu and 0.14 ounce per ton Ag across 31 feet (9.45 m) in Hole #1 and 3.41% Zn, 0.55% Pb, 0.07% Cu and 0.20 ounce per ton Ag across 39 feet (11.89 m) in Hole #2. Prospecting to the southeast also returned anomalous lead values. NOTE: It is uncertain whether these drill results refer to the Salamander Point or the nearby Burning Rock occurrence.
