- Geological Details
- The Pine Channel AA Anomaly Showing is located 2.0 km (1.24 miles) southwest of the south tip of Honsvall Lake and 5.43 km (3.38 miles) east-northeast of the Axis Lake Deposit or SMDI 1623.
The showing area, as mapped by G.L. Colborne, is underlain by Unit 2 or a series of white to dark grey, well foliated, southeast-trending, 20°-25°SW-dipping garnet gneisses. The rocks in this unit grade from feldspathic quartzites through arkoses to greywackes in composition. The differing appearance of the rocks in this unit is caused by the size and percentage of garnets present, by the variable biotite content, and by the portions of potassium and plagioclase feldspar present in the individual rock. One finds local narrow (a few inches to a few feet wide) interbands of magnetite-quartz-garnet iron formation, pyritic iron formation, and narrow norite sills (with limited strike length) within the garnet gneiss.
The showing area lies at the eastern end of the major open, southwest-plunging syncline which also hosts the Axis Lake Deposit to the west. In the showing area, this syncline has been refolded and the axial trace trends northwest-southeast rather than the east-west trend found at Axis Lake.
The AA Anomaly Showing consists of a series of parallel airborne VLF-EM conductors - some of which have coincident magnetic anomalies. The showing consists of a series of narrow iron formation horizons and norite sills within the "garnet gneiss" which host disseminated pyrrhotite-pyrite mineralization plus trace amounts of chalcopyrite and magnetite. Grab sample number 39608 returned 1172 ppm Ni, 709 ppm Cu, and 300 ppm Co.

- Exploration History
- 2/21/1995 Between 1929 and 1930, Dominion Explorers completed prospecting and sampling to the west of the showing area which led to the discovery of the nearby Axis Lake Deposit or SMDI 1623 (AF 74P05-0001). In 1937, E. Harwick completed a geological survey in the immediate Axis Lake Showing area. Eventually the 150 claims staked by Dominion Explorers Ltd. to protect the Axis property were allowed to lapse.
Between 1960 and 1961, G.L. Colborne geologically mapped the showing area at a scale of 1 inch to 1 mile for the Saskatchewan Department of Mineral Resources.
The showing area was next covered by International Nuclear Corporation Permit No. 5. In 1969, they completed an airborne EM, magnetic, and radiometric survey over the property (AF 74P14-0004) and follow-up ground reconnaissance prospecting, mapping, and sampling (AF 74O08-0022). In the following year, Inexco Oil Company acquired the permit and it was designated Inexco Oil and Gas Permit No. 5. They failed to complete any work in the showing area and the permit was dropped.
On 8 December 1981, SMDC acquired MPP 1126 over the showing area. No work was completed in the immediate showing area. The property lapsed on 1 June 1984.
On 14 March 1991, Consolidated Pine Channel Gold staked the showing area as S-103564. In the same year, they completed a helicopter-borne VLF-EM and magnetic survey and a follow-up program of geological mapping, prospecting, sampling, and ground VLF-EM, HLEM and magnetic surveys on the AA grid (AF 74-0011). This work resulted in the discovery of the AA Anomaly Showing. The better results are given above.
