The JD area is underlain by sedimentary rocks of the Carboniferous to Permian Attwood Group and the Triassic Brooklyn Formation. These are intruded by a dioritic stock of the Middle Jurassic Providence Lake Complex.

The Main zone is part of the multiple sub-parallel shear/fracture zones of the north dipping Snowshoe fault that cut Triassic and Permian-aged sediments and volcanics. Two sub-parallel mineralized shear/fracture zones have been identified within the Main zone; the Main shear and Hangingwall shear. One of the best results from trenching in 2003 was 12.28 grams per tonne gold over 5 metres (Exploration and Mining in BC 2003, page 35).

The Main shear is defined by two separate zones of mineralization: the massive pyrite zone and the massive magnetite zone. Mineralization is hosted within a silicified intermediate-mafic volcanic flow plus/minus localized silicified cherty volcanics. The two zones of mineralization within the Main shear visually align along the same trend (300-320 degrees), however, they are mineralogically different. The massive sulphide lenses exposed by trenches JD-04-2 and JD-04-3 trend parallel to sub-parallel to the structural foliation and vary between 1 and 1.5 metres in width. Sulphides are coarse euhedral pyrite in a silica matrix capped by a thick layer of ferrocrete at the rock interface. Trace amounts of molybdenite and chalcopyrite occur in narrow, less than 1 centimetre thick, white quartz veins cutting the pyrite.

The Hangingwall Shear is located approximately 50 metres north of the Main Shear structure. Mineralization within the Hangingwall shear consists of massive to disseminated lenses of coarse euhedral pyrite sub-parallel to the Main shear and dipping between 30–55 degrees to the north. Later stage, spatially-rare, quartz veins with trace chalcopyrite, molybdenum cut the massive pyrite. The host rock units vary from silicified intermediate to mafic flows, cherty volcanics and feldspar-crystal tuffs. Mineralization was further exposed by trenching for an overall strike length of 200 metres.

The JD claim group covers a number of old crown granted claims about which little is known. In the late 1960’s Meridian Exploration Syndicate conducted a geochemical and geophysical survey and diamond drilling program on the property. They report a 21 metre intercept of 0.2% copper although the location of this work is uncertain. In 1970, Granby conducted an IP survey over the property but the details of this work are not known. In the mid-1980s, Consolidated Boundary Exploration, during its work on the adjacent Golden Crown property, also completed 5 drill holes on JD at that time. Noranda conducted significant work on the northwestern part of the JD claim group during 1986 to 1988. Work included grid establishment, soil sampling, geophysics, 26 trenches, 8 diamond drill holes totaling 672 metres and 10 reverse circulation drill holes totaling 1078 metres. Results were encouraging. A 1 kilometres long elevated gold soil anomaly was identified. Trenching over a 90 metres strike length of the 1 kilometre long anomaly identified sub-parallel mineralized shear zones. Follow-up work recommended by Noranda was never completed. Noranda allowed the claims to lapse in 1995.

In 1995, the area was re-staked as the JD claim group by partners John Kemp, Don Hairsine and George Nakade. Pender Gold Corp. optioned the property in 1997, established a new grid, conducted mapping, ground magnetics and VLF and completed 5 diamond drill holes in the area of the Noranda drilling. Pender dropped the option in 1999.

Gold City Industries Ltd. optioned the JD claim group in 2002 and conducted a 2003 and 2004 work program consisting mainly of trenching. The 2004 program consisted of 1662 metres of excavation in 10 trenches. Merit Mining Corp. (formerly Jantri Resources Inc.) exercised its option to acquire a 100% interest in Gold City Industries Ltd.’s British Columbia assets, pursuant to an option agreement dated September 15, 2004.
