The JJF occurrence is underlain by dominantly metasedimentary rocks of the Hadrynian to Lower Paleozoic Snowshoe Group. In this area the Snowshoe Group comprises limestone, phyllite and quartzite. These rocks have been regionally metamorphosed to greenschist facies.

In 1987, two drillholes were sited by Poschner Construction Ltd in an area where coarse, sphalerite-quartz-quartzite breccia was observed and sampled.

DDH 1 encountered interbedded phyllite, graywacke and quartzite cut by galena and pyrite-bearing quartz veins. No significant gold values are reported, but two intervals carried silver in association with the sulphides. In DDH 1, a quartz veined section from 0 to 3 metres, assayed 4.08 per cent lead, 2.76 per cent zinc and 25.37 grams per tonne silver; sulphide-bearing phyllite from 6 to 9 meters assayed 2.32 per cent lead, 1.54 per cent zinc and 21.6 grams per tonne silver (Assessment Report 16755).

DDH 2 intersected interbedded phyllite, quartzite and chloritic phyllite with pyrite and galena-bearing quartz veins. No significant gold analyses are reported, but a 30 centimetres section of sulphide-rich phyllite, assayed 12.2 per cent lead, 4.58 per cent zinc and 108.0 grams per tonne silver (Assessment Report 16755).
