At the Burt showing, bedded argillites of the Helikian Aldridge Formation (Purcell Supergroup) have been crosscut by a diorite dyke 9 to 12 metres thick. Quartz has filled fractures within the dike and in the country rock and is host to blebs of galena, sphalerite and minor chalcopyrite and pyrite. The dike generally strikes 285 degrees with a steep southerly dip. Mineralization is similar to other showings in the area. A rockslide had covered the area of the adits and trenches by 1952.

Location Notes: A 1997 internal report for Gallowai Metal Mining (PFD 676699, page 4) reports a UTM coordinate for the Burt zone as 5474200N and 632500E which places it about 400 metres northwest of the O.K. MINFILE plot (082GSW055); the 1997 report itself refers the UTM coordinate back to the 1937 Minister of Mines Annual Report. The 1997 report further states that the Burt zone occurs 4 kilometres due east of the Treasure zone (Peacock Copper? (082GSW017)) on the southwest flank of Mountain No.1 of the Lizard Range, possibly putting the Burt zone some 4 kilometres south of the O.K. zone (MINFILE plot); at the same time the report states the O.K. zone is located 6 kilometres east-northeast of the Burt zone on the southern flank of Mountain No.1, possibly locating Burt near Rosen Lake. Assessment Report 19034 has the Burt zone located immediately south of the Empire-Strathcona claims (082GSW015). The original MINFILE description plots the Burt zone just north of the Empire-Strathcona claims. More recent reports use the default MINFILE plots for their own map location and show significant uncertainty of location. Also see Figure 4 of the 1997 report (PFD 676699), Burt drilling locations in Assessment Report 25130, and Map No. 122 in Open File 1988-14 (MINFILE location chosen) for further clarification (or confusion).

A narrow high-grade lead, zinc and silver vein occurs about 4 kilometres due east of the Treasure Zone on the southwest flank of Mountain No. 1 of the Lizard Range. One assayed sample was reportedly taken from a three-quarter metre wide section of the vein and found to contain 6.5 per cent lead, 3.4 per cent zinc, and 30.9 per cent silver (Exploration Report for Gallowai Metal Mining Corporation, September 22, 1997, Property File Document (PFD 676699)). The vein, as indicated from trenches, strikes to the northeast for a distance of over 600 metres and dips from near vertical to seventy-five degrees dip. Two adits and some trenching that had previously exposed the vein have since caved in.

The results of a 1997 drilling program near the Burt Zone revealed the presence of a thick sequence of carbonate rocks that had been subjected to contact metamorphism, an indication of intrusive rocks. In this area the Proterozoic age metasediments were thrust over the younger Paleozoic carbonate sequence. The drilling penetrated through the Proterozoic into the Paleozoic sequence, and the Paleozoic sediments. See PFD 676699 and Assessment Report 25130.
