The Dar occurrence, consisting of one of four mineralized quartz veins with silicified wallrocks, is located 12.5 kilometres northwest of the Alberts Hump occurrence (094E 085), and 8.5 kilometres northeast of the confluence of Adoogacho Creek with the Stikine River (Assessment Report 11150). Smithers is 310 kilometres to the south.

The showing 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 Takla Group andesite flows and pyroclastic rocks. Takla volcanics have been intruded by the granodiorite to quartz monzonite Black Lake Suite of Early Jurassic age 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.

Regional mapping has indicated that the Dar showing is underlain by grey and maroon feldspar porphyry tuffs of the Adoogacho Member of the Toodoggone Formation. On a regional scale, the Adoogacho Member is described as consisting of trachydacite ash flow tuffs, lapilli and finer tuffs, volcanic sandstone and conglomerate, and subvolcanic plugs (Bulletin 86).

On a property scale, the Adoogacho Member has been subdivided into four lithologies; grey porphyry tuffs, maroon porphyry tuffs, quartz vein and potassium feldspar altered tuffs adjacent to quartz veins (Assessment Report 11150). The units are flat lying and are conformable with one another.

Silicification is commonly evident in tuffs adjacent to quartz veins. Four quartz veins have been identified on the Dar claim. The quartz veins strike 058 degrees and are steeply dipping. All four quartz veins are less than 1 metre wide and the largest is exposed for a strike length of 5 metres. Minor galena, sphalerite and chalcopyrite occur erratically within quartz veins which are occasionally vuggy. Alteration consists of a small (less than 1 metre) potassium feldspar envelope around quartz veins.

In 1982, ten rock chip samples were taken from these veins and associated altered tuffs. The best values, from three chip samples across the same vein, are 5.7 grams per tonne silver, 0.67 gram per tonne gold, 0.128 per cent copper, 0.162 per cent lead and 0.098 per cent copper (Assessment Report 11150).

In 1988, two samples (WM-24 and -25) from mineralized quartz veins yielded 1.32 and 1.88 grams per tonne gold, respectively (Assessment Report 18465).

Work History

In 1982, the Dar claim was staked by Newmont Exploration of Canada Limited after prospecting had located four small, less than 2 metre wide quartz vein zones containing minor amounts of erratically distributed galena, sphalerite and chalcopyrite mineralization. A total of 10 rock chip samples were collected from several locations on the quartz veins. In addition, mapping was completed at a scale of 1:500.

In 1985, Newmont Exploration of Canada Ltd. completed a program of prospecting and soil sampling on the Dar claim.

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).

In 2006, A. Birkeland collected five stream sediment samples (moss mat where possible) and ten rock chip samples from three areas on the Gaucho claims.
