The Bullion showing is located about 30 kilometres east-northeast of Stewart, 900 metres north of Del Norte Creek, and approximately 1.3 kilometres northeast of the toe of the Del Norte Glacier. The Porter adit occurs to the south.
According to Bulletin 63 the area is underlain by Hazelton Group rocks comprising a north trending strip of volcaniclastics (Lower Jurassic Betty Creek Formation), flanked to the east and west by sediments. More recently, the showing has been reported to lie close to the contact between Hazelton Group volcanics to the west and overlying Middle-Upper Jurassic Bowser Lake Group argillites to the east.
Geochemical sampling in 1988 outlined anomalous gold and silver values in pyritized tuff. Silt samples from a stream draining the tuff assayed anomalous gold, silver, copper, lead, zinc and molybdenum. Boulders containing massive pyrite, pyrrhotite, sphalerite and galena have been found in Del Norte Creek (Assessment Report 17660). The source of these boulders is not known.
Float at the Bullion zone contained pyrite, chalcopyrite and galena. The zone occurs in intermediate ash lapilli and plagioclase crystal tuffs near a belt of strongly phyllic and argillically altered volcanics and plagioclase hornblende porphyry dikes. A one metre chip sample taken from the Bullion area in 1991 assayed 1.14 grams per tonne gold, 54.85 grams per tonne silver, 0.13 per cent lead, 0.012 per cent zinc and 0.003 per cent copper (sample DNLGR-306, Assessment Report 21535). The sample came from a fault zone with abundant quartz stringers.
In 1992, a quartz sulphide vein, the NMG vein, was discovered about 150 metres north of the Bullion showing. The vein outcrops intermittently over a distance of 225 metres and lies along the sedimentary-volcanic contact, similar to the LG vein (104A 161) discovered in 1990. The highest assay came from a one metre chip sample across the vein at its southern exposure. The sample assayed 10.6 grams per tonne gold and 571.45 grams per tonne silver (sample DM-MR-82646, Assessment Report 22103).
A copper-gold zone on the Croesus 2 claim (103P), in the Hardpan Creek area to the south of the Bullion showing, assayed 8.7 per cent copper across 8.1 metres; one sample assayed 22.6 grams per tonne gold across 2.7 metres (Northern Miner March 6, 1989). The Bullion area is probably the northern extension of the altered belt of rocks that hosts this zone.
Work History
The Bullion showing area was originally staked and explored by Porter and Mowat before 1913. A short adit (Porter) was driven between 1913 and 1922. In 1922, Green and Ficklin restaked the ground as the Del Norte claim group. In 1939, the Premier Gold Mining Company completed a series of 15 opencuts in and around the Porter and Bullion showings. At this point the property was known as the Meziadin group. In 1982, Viscount Resources conducted limited prospecting, mapping and trenching on Willoughby Creek and Del Norte Creek and several electromagnetic (EM) anomalies were delineated from a geophysical survey. In 1987, Teuton Resources Corp. staked the Croesus 1-4 claims over the area and conducted rock and silt geochemical sampling the following year. In 1988, Teuton Resources conducted follow-up exploration in the Bullion and Hardpan Creek areas. In 1989, Goodgold Resources Ltd. optioned the property and performed a heli-borne VLF-EM and magnetometer survey over the area. In 1991 and 1992, Goodgold conducted mapping, sampling, trenching, geochemical and geophysical surveys and diamond drilling (in the Hardpan Creek area). In 2005, a helicopter-borne AeroTEM II electromagnetic and magnetic survey was carried out on behalf of Teuton Resources Corp. over the Del Norte-Midas property and a total of 1299.5 line-kilometres was flown. In 2016, Teuton Resources completed 13 diamond drill holes, totalling 1822.4 metres, on the Del Norte property. During 2017 through 2019, Teuton Resources completed programs of geochemical (rock and soil) sampling, an airborne geophysical (ZTEM and magnetic) survey and four diamond drillholes on the Del Norte property.
