The DR occurrence, discovered in 1988, is exposed on a north-trending ridge situated approximately 8 kilometres southeast of the confluence of the Chukachida and Stikine rivers and 269 kilometres northwest of the community of Germansen Landing.

The prospect is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Devonian-Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Stuhini Group andesite flows and pyroclastic rocks. These Stuhini rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The DR prospect is underlain by Stuhini Group brecciated augite porphyry andesites and basalts. Mineralization, exposed in a number of outcrops scattered over an area of 400 by 300 metres, consists of bornite, pyrite, chalcopyrite, chalcocite, malachite and chrysocolla hosted within quartz-calcite veins and veinlets. The volcanic rocks associated with the mineralization is brecciated and argillically to propylitically altered.

Typical assay grades of the veins is 1.52 per cent copper and 13.50 grams per tonne silver (sample WM-76 on Fred 4 claim, Assessment Report 18465). The highest assay obtained, 17.1 per cent copper and 136 grams per tonne silver, was from a 10-centimetre quartz-calcite vein containing up to 20 per cent bornite and 25 per cent pyrite (sample DR-29 on Fred 3 claim, Assessment Report 18465).

Work History

In 1986, Prolific Resources Ltd. completed a reconnaissance stream silt sampling program on the Stik 5 and Fred 1 claim. A brief reconnaissance geological mapping and prospecting program was carried out on these claims in 1987.

In 1988, on behalf of Prolific Resources Ltd., a field exploration program was completed on their 'Toodoggone' properties comprising the Stik, Fred, Adoog, Doog, Jim and Mike claims. The objective of the program was to locate and evaluate the gold potential of epithermal quartz breccia systems on the claims. Exploration consisted of extensive prospecting, geological mapping, lithogeochemical sampling (355 rock), hand trenching (1 trench, 19 metres), and soil sampling (722).
