The Gold Nose Ridge occurrence is located at an elevation of approximately 1600 metres on a north-trending ridge, southeast of Jock Creek and approximately 3.3 kilometres south-southwest of the creekâs junction with the Toodoggone River.
Regionally, the area 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 Paleogene sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.
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, and marine sedimentary and volcanic rocks of the Lower to Middle Jurassic Hazelton Group. These 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 calc-alkaline volcanics of the Toodoggone Formation (Hazelton Group).
The dominant structures in the area are steeply dipping faults that 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.
Locally, propylitically altered tuff hosts chlorite-altered boxwork quartz veins with pyrite, chalcopyrite, galena and sphalerite mineralization.
In 2004, two samples (165341 and 165343) yielded 1.814 and 6.513 grams per tonne gold, 31.7 and 47.4 grams per tonne silver, 0.844 and 0.052 per cent copper, 0.188 and 0.256 per cent lead with 0.059 and 0.655 per cent zinc, respectively (Assessment Report 27634).
Work History
In 2003 and 2004, Stealth Minerals Ltd. completed programs of prospecting, geological mapping and rock, silt and soil sampling on the area as the Nub claims and identified the Nub Stockwork and Nub Skarn zones.
In 2016, Amarc Resources Ltd. completed a program of soil sampling on the area as the Joy property. The following year, a program of rock and soil sampling, geological mapping, a 49.0 line-kilometre ground induced polarization survey and a 470.0 line-kilometre airborne magnetic survey were completed. Also, during this time, Pacific Empire Minerals Corp. completed programs of rock and soil sampling, geological mapping and a 62.0 line-kilometre airborne magnetic survey on the area immediately east as the Nub East property.
In 2018, Amarc Resources completed a program of rock and soil sampling, geological mapping, a 63.0 line-kilometre ground induced polarization survey and a 1470.0 line-kilometre airborne magnetic survey on the area.
