Capsule Geology

The JK occurrence is located approximately 7.75 kilometres south-southwest of Bend Mountain, south of the Toodoggone River, and 5.5 kilometres northwest of the Finlay River. Smithers is 290 kilometres to the south.

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, minor occurrences of chalcopyrite, sphalerite, galena and hematite have been identified in the volcanic rocks.

In 2003, a chip sample from propylitic- to sericite-altered volcanics in proximity with a feldspar porphyry dike yielded approximately 1 gram per tonne gold over 1.5 metres (Assessment Report 27429).

In 2004, a grab sample (148002) of quartz vein with galena in granodiorite assayed 0.13 gram per tonne gold, 2.1 grams per tonne silver and 0.908 per cent lead (Assessment Report 27634).

Work History

In 1971, Cordilleran Engineering Ltd. completed an induced polarization and resistivity survey on the area as the J.K. claim. This work identified minor occurrences of chalcopyrite, sphalerite, galena and hematite in the volcanic rocks associated with an electromagnetic conductor coinciding with a very extensive copper geochemical anomaly on the flank of a sharply positive magnetic feature.

In 1980 and 1981, Serem Ltd. completed programs of prospecting; geological mapping and rock, silt and soil sampling on the area as the Nub Mountain 1-5 claims. During 1987 through 1989, Toodoggone Gold Inc. completed programs of geological mapping, geochemical (heavy mineral, rock, silt and soil) sampling, trenching and a 248.0 line-kilometre airborne magnetic and electromagnetic survey on the area as the Fine 1-4 claims.

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.

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.
