The JK occurrence is located 3.8 kilometres east-southeast of the summit of Alberts Hump, south of Abesti Creek, and 2.5 kilometres due south of the AL (Bonanza) occurrence (094E 079), approximately 300 kilometres north of Smithers. It lies within the Omineca-Cassiar mountains in the west-central portion of the Toodoggone Gold Camp.

The JK prospect 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 Tertiary 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 Takla Group andesite flows and pyroclastic rocks. These Takla 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 calcalkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults which 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.

The Adoogacho and Metsantan members of the Toodoggone Formation underlie the AL property. The Adoogacho Member consists of trachydacite ash-flow tuff with lenses of lapilli tuff, rare marlstone, and conglomerate near the base. The Metsantan Member is composed mainly of trachyandesite (latite) flows with lenses of lapilli tuff, and lahar; minor volcanic sandstone and conglomerate (Bulletin 86). The Metsantan Member, in part, directly overlies the basal Adoogacho Member and is also in fault contact with it.

The JK prospect consists of an undrilled zone of silicification hosting pyrite. This zone has been trenched over a 170-metre strike length and remains open to the south. Up to 11 metres of pyritic silicification with anomalous gold values is flanked by intense argillic alteration. A strong gold-in-soil geochemical anomaly continues 130 metres to the south (Assessment Report 15735). Seven of 9 trenches on the JK prospect uncovered silicification hosting anomalous gold values (Assessment Report 15735). Weighted averages of gold mineralization ranged from 1.36 grams per tonne (Trench D) to 4.60 grams per tonne (Trench H), using a 1.00 gram per tonne cut-off grade (Assessment Report 15735). The brittle silica hostrock carries abundant pyrite (up to 15 per cent); only traces of barite were noted and the silica lacks the porosity typical of the high-grade zones nearby.

In 1988, Energex Minerals Ltd. drilled the JK in two holes that totalled 167.0 metres. The holes tested the central part of the zone, below the widest and highest-grade mineralized intervals exposed in the 1986 trenches. Drillhole 88-13 yielded an intercept of 5 metres (core length) grading 2.17 grams per tonne gold (Bowen, 2012).

In 2007, Christopher James Gold Corp. conducted a helicopter-borne magnetic gradiometer survey consisting of 2229 line-kilometres over all historic gold deposits and MINFILE occurrences on the property, including the Alberts Hump area. Maps completed include coloured Total Magnetic Intensity, Measured 3-D Analytic Signal, Measured Vertical Magnetic Gradient, and colour-shaded Tilt Derivative of the Total Magnetic Intensity.

See Bonanza (094E 079) for further geological and work history details of the Ranch (Al) property. This JK prospect is presently (2014) contained within the Ranch (Al) property, along with a number of other prospects.
