The Jeckle occurrence is located on a southeast-trending ridge, northeast of the Sturdee River and approximately 4.5 kilometres northwest of Black Lake.
The area lies within the Omineca-Cassiar mountains at the southern end of the Toodoggone gold camp and is situated within a Mesozoic volcanic arc assemblage that lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Neogen 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. Takla volcanics have been intruded by the early Jurassic granodiorite to quartz monzonite 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.
The area is underlain by a discontinuous sequence of Permian to Middle Jurassic volcano-sedimentary rocks upwarped against and in fault contact with the early Jurassic quartz monzonite to syenite Black Lake stock. The dominant lithologies are augite feldspar phyric andesitic flows of the Takla Group and feldspar porphyry of the Toodoggone Formation. Other lithologies cropping out in the vicinity include limestone and marble of the Asitka Group, and porphyritic andesitic crystal and lithic tuffs and breccias. Structurally the units in the area are intensively disrupted by steep-dipping, northeast-striking faults.
Locally, a reddish fine-grained granodiorite hosts gold and silver values.
In 1988, a grab sample (32376) assayed 103.0 grams per tonne silver and 0.718 gram per tonne gold (Assessment Report 18026).
In 2020, rock samples from the Jeckle occurrence area are reported to have yielded from 0.25 to 1.0 gram per tonne gold and greater than 80 grams per tonne silver (P&E Mining Consultants Inc. [2021-06-28]: Technical Report and Updated Mineral Resource Estimate of the Lawyers Gold-Silver Property, Omineca Mining Division, British Columbia, Canada).
Work History
In 1985, the Toodoggone Syndicate completed a program of heavy mineral and soil sampling on the area immediately east as the Black claims. The following year, an airborne magnetic survey was completed on the area. Also at this time, First Allied Resources completed a program of rock, silt and soil sampling on the Black claims.
In 1987 and 1988, Beachview Resources Ltd. completed program of geological mapping and geochemical (rock, silt and soil) sampling on the area as the Jeckle claim. Also, in 1988 and 1989, Lexington Resources Ltd. completed a 100 line-kilometre airborne magnetic survey and a 1.9 line-kilometre ground magnetic and electromagnetic on the area.
In 2019 and 2020, Benchmark Metals Inc. completed programs of geochemical (rock and soil) and biogeochemical sampling, ground and airborne geophysical surveys, 242 diamond drill holes, totalling 69 080 metres, and 191 reverse circulation drill holes, totalling 28 395 metres, on the area as part of the Lawyers property. The majority of the drilling targeted the Cliff Creek, Dukes Ridge, Phoenix and AGB zones of the Lawyers (MINFILE 094E 066) deposit.
