The MIP showing is located on the Pim 9 claim east of Partridge Lake and south of the Yukon border.
The area occurs on the eastern edge of the Cretaceous to Tertiary Coast Plutonic Complex near the boundary with folded Mesozoic and Paleozoic volcanic and sedimentary rocks of the Whitehorse Nechako trough.
The showing area is underlain hornblende biotite quartz monzonite of the Paleocene to Eocene Sloko-Hyder Plutonic Suite or by Middle Eocene intrusions. These are cut by steeply dipping porphyritic rhyolite "ring" dikes. The main structural features comprise concentric and radial fracture systems, two nested calderas and a central dome over Partridge Lake.
One significant showing, the MIP vein, and four minor occurrences have been discovered on the claims. The mineralization is controlled by north-northeast trending structures. The MIP vein structure, gossanous with boxwork weathering, is traceable for over 500 metres. A float boulder of quartz vein material similar to the MIP vein was found 600 metres to the east. The northern part of the structure consists of a 2-metre-wide chlorite-epidote-hematite alteration zone in quartz monzonite with sheeted quartz veins up to 5 centimetres wide. The vein widens to the south where the vein is 0.5 to 5 metres wide and can be traced for 280 metres. Further to the south, where exposure is limited, the vein is still open.
The vein consists of massive sugary, honey-colored to white quartz, some euhedral quartz crystals in vugs and sericite with minor amounts of clay. Mineralization consists of pyrite (up to 5 per cent), minor galena, sphalerite, and chalcopyrite in crystal clusters up to 3 millimetres. The margins of the vein are altered.
In 1988, a program of preliminary geological mapping and prospecting, as well as rock -, talus fines - and stream sediment silt sampling was completed on behalf of Ernie Bergvinson. A total of 27 silt -, 402 talus fines - and 80 rock samples were collected from the property.
Samples from the vein assayed up to 66.5 grams per tonne silver, 0.75 grams per tonne gold, 0.78 per cent lead, 0.1 per cent copper and 0.14 per cent zinc. Sample ’88-4B-4R 16’ returned 24.4 grams per tonne silver, 0.75 grams per tonne gold, 0.15 per cent lead, 0.1 per cent zinc and 0.02 per cent copper (Assessment Report 17970). The best mineralization occurs in a 5-centimetre-wide quartz vein on the edge of a 5-metre-wide rhyolite dike. This dike parallels the main MIP vein 50 metres to the east.
On the steep west facing slopes above the south end of Partridge Lake, numerous gossanous quartz veins, with up to 1 per cent pyrite, occur. The veins have associated chlorite-sericite-hematite alteration zones, up to 40 centimetres wide, in quartz monzonite. Samples from these veins assayed up to 56.9 grams per tonne silver and 0.19 per cent lead and were anomalous in arsenic and gold as well (Assessment Report 17970).
On the northwestern part of the claims, a large east-striking shear zone is 20 metres wide. One sample assayed 4.45 grams per tonne silver and 0.17 per cent copper (Assessment Report 17970).
