The Nub (Stockwork) occurrence is located at an elevation of approximately 1900 metres on a northeast-facing slope, southeast of Jock Creek and approximately 3.9 kilometres south-southeast of the creek’s 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, an area of 4 to 8 per cent quartz stockwork is hosted in Lower Jurassic Toodoggone Formation (Hazelton Group) flows and tuffs. The stockwork quartz±carbonate±barite veins are generally narrow, with a maximum width of 1 metre. Mineralization consists of chalcopyrite-pyrite-galena±sphalerite

In 2004, a sample (185577) of medium-grained volcanic rock with malachite staining assayed 10.7 grams per tonne gold, 205 grams per tonne silver and greater than 1 per cent copper (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 and 2017, 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 as the Nub East property.
