- Drill hole FON-431, spudded at FON grid 141 coordinates 7+50N and 2+00E, discovered the mineralization which constitutes this showing. Drill hole FON-431 is located northeast of Suggi Lake and 4.3 miles (6.9 km) northeast of the Suggi Lake Cu-Zn-Ag Zone (SMDI 2709).
The discovery hole passes through 6.6 m (21.7 ft) of muskeg, mud, clay and dolomite boulder overburden then 26.4 m (86.6 ft) of buff, fine-grained, massive dolomite which overlies 8.0 m (26.2 ft) of grey to buff, well-sorted, poorly consolidated Winnipeg sandstone. The sandstone overlies a 24.0 m (78.7 ft) thick Paleozoic regolith of weathered, grey to green, soft talcose material which is likely weathered dacite with minor intruded pegmatite (10% talc and 5% clay).
The regolith is underlain by 25.8 m (84.6 ft) of grey to brown, plagioclase-phyric, medium- to fine-grained, biotite and hematite altered and bleached regolith weathered basalt with minor red pegmatite. This weathered basalt contains 2% hematite and trace amounts of pyrite and magnetite, present as fracture coatings.
The basalt is underlain by 0.8 m (85.8 to 86.7 m) brown to bronze, medium-grained, recrystallized 40% to 70% near solid sulphide which contains up to 30% pyrrhotite, 12% chalcopyrite, 12% sphalerite, and 2% magnetite fracture fill type mineralization. The horizon is well fractured, and clay-altered, silicified, and carbonatized. This horizon is separated from a second 0.5 m wide (87.2 to 87.7 m) horizon of identical near solid sulphide by 0.7 m of regolith-weathered pegmatite.
The second mineralized horizon is underlain by 22.5 m (73.8 ft) of grey, fractured, fine-grained bleached pegmatite. The unit contains numerous mud seams and minor intervals of metadiorite.
The pegmatite is underlain by 0.1 m (119.5 to 119.6) of bronze to brown, near-solid sulphide mineralization which contains biotite and amphibole porphyroblasts. The unit contains up to 3% pyrite, 2% pyrrhotite, 5% chalcopyrite, 40% sphalerite, and trace magnetite. This is underlain by 7.1 m of light grey, contorted, silicified meta-rhyolite which is underlain by a narrow (0.2 m) interval of medium grey dacite flow rock.
The dacite rests on a fourth 0.4 m (1.3 ft) thick (130.3 to 130.7 m) interval of near solid sulphide which contains up to 3% pyrite, 7% pyrrhotite, trace chalcopyrite and sphalerite, and 20% magnetite.
This is underlain by 15.8 m (51.8 ft) of interlayered metadacite and meta-rhyolite. This volcanic interval is underlain by over 105 m (344.5 ft) of light grey to light red, medium-grained, contorted granite gneiss (granite to granodiorite) with patches of pegmatite.
Drill hole FON-437, intersected 2% pyrite, 30% po, 6% chalcopyrite, and 10% sphalerite as medium to coarse grained near solid sulphide mineralization in a metadacite alteration zone
The mineralized intervals returned the following values:

- Exploration History
- 6/1/2001 On 21 March 1983, Granges Exploration AB was granted MPP 1138 over the showing area. The MPP lapsed in August of 1988.
On 10 October 1996, J. Custer staked the showing area as CBS 3879 for Hudson Bay Exploration and Development Company Limited. In the winter of 1997, Hudson Bay Exploration completed a ground EM and magnetic survey (AF 63L-0013) and a ground TDEM survey (AF 63L-0015) on the FON 141 grid to further delineate a series of spectrum EM anomalies. In the following year, Hudson Bay comnpleted drill hole FON-431 to test one of these anomalies (AF 63L07-0010. The hole encountered the mineralization which constitutes this showing. A bore hole PEM survey was conducted (AF 63L07-0013).
In 1998, a ground TDEM survey was completed on the FON 141 grid (AF 63L07-0012). In 1999, Hudson Bay completed drill hole FON-437 on the showing (AF 63L-0017). The hole encountered base metal mineralization with values which are reported above. A bore hole PEM survey was completed on the hole (AF 63L07-0014). In 2001, Hudson Bay Exploration completed a borehole TDEM survey on hole FON-431 (AF 63L07-0016).
In 2002, Hudson Bay deepened hole FON-437 and completed holes FON-442 and FON-443 on the showing (AF 63L07-NE-0018). In the following year, Hudson Bay completed drill holes FON-444 and -445 on the zone (AF 63L07-NE-0019). Better intersections encountered are reported above. In the following year, Hudson Bay Exploration completed borehole PEM surveys on drill holes FON-444 and FON-445 (AF 63L07-NE-0020). They also completed a ground TDEM survey over the FON-141 grid that covers the showing (AF 63L07-NE-0021).
