The ARCTIC occurrence is located at an elevation of approximately 1440 metres on the northwest end of a north trending ridge, approximately 4.9 kilometres south-southeast of the junction of Lawyers Creek and the Toodoggone River.
The area lies within the Omineca-Cassiar Mountains at the southern end of the Toodoggone gold camp. The area 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 Neogene 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 Lower Jurassic granodiorite to quartz monzonite of the 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 occurrence area is underlain by andesite crystal tuffs, volcaniclastic breccias and hypabyssal quartz trachyandesites, part of a larger package of Toodoggone Formation volcanics assigned to the Metsantan Member. Other lithologies of the Metsantan Member include mostly latite lava flows with interflow lahar, and a mix of epiclastic and pyroclastic rocks (Bulletin 86).
Locally, a feldspar-hornblende porphyry hosts a narrow, 3- to 5-centimetre-wide zone of silica veinlets with epidote alteration haloes and disseminated pyrite.
In 2018, a rock sample (Y445373) assayed 0.337 gram per tonne gold and 47.7 grams per tonne silver (Assessment Report 38447). In 2021 a rock sample (F0120504) from the Arctic showing (E-grid) returned 4.31 grams per tonne gold and 110 grams per tonne silver (Assessment Report 40958).
Work History
The area has been explored in conjunction with the nearby Silver Pond (West) occurrence (MINFILE 094E 163) and a complete exploration history of the area and property can be found there.
From 2018 through 2022, Benchmark Metals Inc. completed programs of geochemical (rock and soil) and biogeochemical sampling, ground and airborne geophysical surveys, diamond drilling and reverse-circulation drilling on their Lawyers property, including the Artic occurrence.
On September 30, 2022, JDS Energy & Mining Consultants Inc. produced an updated Preliminary Economic Assessment Lawyers Gold-Silver Project, Stikine Terrane, B.C. for Benchmark Metals Inc. In August 2023, Benchmark Metals Inc. merged with Thesis Gold Inc., joining the Lawyer Project operations with Thesis Gold's Ranch Project located in similar Toodoggone Formation rocks to the northwest.
