The Dan showing is hosted by the Upper Triassic to Lower Jurassic Hazelton Group, Unuk River Formation metavolcanics. The Hazelton Group is a northwest trending steeply east dipping belt of folded andesitic lapilli tuffs, flows and breccia containing a thick sequence of argillite and siltstone infolded along a synclinal axis. The sequence is intruded by the Early Jurassic Texas Creek plutonic suite of dacitic porphyry dykes.

The 2.1-metre-wide mineralized quartz vein is exposed in the main trench hosted in silicified and pyritized andesitic volcanics. A north striking steeply east dipping shear zone occurs to the east and to the west there are several moderately west dipping faults. The vein appears to have been emplaced in a cross fracture in a mineralized zone similar to the geological setting of the Silbak Premier deposit (104B 054). The mineralization consists of pyrite, streaks of mixed galena and sphalerite and minor chalcopyrite with quartz and carbonate gangue. The vein is crosscut by narrow quartz veinlets. It is believed that the vein persists for 33.5 to 39.5 metres from the main trench into a network of quartz stringers mineralized with minor sulphides. A sample across 1.8 metres from an open cut (location uncertain) assayed 12 grams per tonne gold and 342.8 grams per tonne silver (Groves, 1981).

Based on drilling on the Dan zone in the mid-2000s by Pinnacle Mines (Jayden Resource), the Dan zone consists of a silicified breccia stockwork composed of a lower section containing narrow bands of massive sphalerite, galena, chalcopyrite and pyrite with a middle portion containing quartz with local coarse native gold and an upper portion containing patches and disseminations of the sulphides noted above. The zone appears to be 45 metres in true thickness and assay results, greater than 0.2 gram per tonne gold indicates at least 150 metres of depth extent where drilled (DDH 2005-64 and DDH2005-74). The vein appears to strike north 29 degrees east and has an apparent west dip. It has been traced over a strike length of 300 metres from the area of DDH-2005-71 to 79 south to trench 2005-57.

On surface, at the top of Dan Hill, the exposed mineralization consists of semi-massive pyrite streaks, mixed galena and sphalerite and minor chalcopyrite as well as narrow quartz stringers mineralized with minor sulphides. At the south end trenching has exposed a semi-massive sulphide vein over 4 metres wide with pyritic, chloritic rocks in the south wall and sericitic rocks with 10 per cent pyrite-minor sphalerite along schistosity in the north wall. Greenockite staining is common in the southern sulphide portion of the zone.

Diamond-drill hole 2006-98 intersected 12.17 metres grading 8.30 grams per tonne gold, 14.80 grams per tonne silver, 0.019 copper, 0.21 per cent lead, and 0.86 zinc (Assessment Report 29383).

Work History

In the early 1930s, a short adit was completed on the Dan mineralized showing. In 1967, Granduc Mines cleared the adit into the Dan showing and completed sampling and trenching. In 1981, E.W. Grove compiled a geological report on the Dan claim based on his site visit in 1967 (Grove, 1981).

In 2005, 2 diamond-drill holes were completed on the Dan Zone and resulted in an observed extension of its known mineralized length (CNNMatthews Dec,14,2005).

In 2006, Pinnacle Mines drilled 2405 metres in 13 holes (DDH-2006-92 to 103) on the Dan Fraction claim to test the Dan zone mineralization outlined during the 2005 drilling. Information on the 2005 drill program is not published.

In 2010, Jayden Resources Inc (formerly Pinnacle Mines) drilled one drill hole on the Dan Fraction (hole SC10-311). It was drilled to the northeast to infill a part of the southern portion of the Main Breccia zone (104B 150) and to intersect and crosscut the Main Breccia zone. The Dan zone occurs on the boundary of the Main Breccia zone, but this hole appears to not have been sited to intersect the Dan zone.
