The BG North (JC 5) occurrence is located on a south-facing slope of an east-flowing tributary of Jock Creek, approximately 1.5 kilometres southeast of The Pillar.

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, a silicified monzonite hosts oxidized quartz veins with gold and silver values.

In 2003, three samples (133293, 133074 and 133073) yielded from 0.16 to 0.46 gram per tonne gold and trace to 47.6 grams per tonne silver (Assessment Report 27429).

In 2004, a sample (185905) taken across 20.0 metres of silicified monzonite assayed 176.3 grams per tonne silver and 1.49 grams per tonne gold, whereas another chip sample (185910) of oxidized quartz vein material assayed 0.83 gram per tonne gold and 98.1 grams per tonne silver over 1.0 metre (Assessment Report 27790).

Work History

During 2003 through 2006, Stealth Minerals Ltd. completed programs of prospecting; geological mapping and rock, silt and soil sampling on the area as the JC claims of the Sickle-Sophia, Nub and Bee Gee properties.

During 2016 through 2018, Amarc Resources Ltd. completed programs of soil and rock sampling, geological mapping, 115.0 line-kilometres of ground induced polarization surveying and 1940.0 line-kilometres of airborne magnetic surveying on the area as the Joy property.
