Swan Zone


A precious metal-rich gossan

History of the Swan Zone

The Swan zone area was staked to cover a historical molybdenum-copper porphyry prospect that was discovered in the late 1960s and explored periodically since then. Despite more than 500 soil and surface rock samples and almost 1,000 meters of shallow diamond drilling, no geochemical analysis for gold was ever completed in the period before Trailbreaker staked the area in 2020. Historical geological mapping and drill hole logging indicate a complex intrusive system, comprising widespread quartz-feldspar porphyritic monzonite cut by a variety of felsic and mafic dikes. Molybdenite-pyrite mineralization is closely associated with sheeted quartz veins, quartz stockwork and breccia zones. The historical drilling at Swan intersected broad, low to mid-grade molybdenite mineralization, returning up to 0.06% Mo over 73 meters, as well as several significant silver intercepts including > 26 g/t Ag over 3 meters.

Trailbreaker Resources’ Exploration at Swan

In 2021 a soil sampling grid, adjacent to the historical drilling, was designed to test a large gossanous ridge top. Assay results from the soil sampling revealed a ~900m x 700m Au-As-Ag-Sb-Cu-Mo-Pb soil anomaly, with soil samples assaying up to 406 ppb Au and 12.9 g/t Ag. The core of the soil anomaly is located ~1.2km east of the historical drilling. The anomaly occurs within a leucogranite-porphyry unit of the Upper Cretaceous Glundebery Batholith.

Follow-up prospecting in this area uncovered significant arsenopyrite mineralization in bedrock, proximal float, and talus float. Rock samples taken from the core of soil anomy at a mid-slope outcrop returned grades up to 11.5 g/t Au with 16.8 g/t Ag and 8.39 g/t Au with 55.8 g/t Ag. Additional samples obtained from float within the anomaly have yielded grades of 11.7 g/t Au, 212 g/t Ag, and 0.12% Cu.

In 2022, a reconnaissance soil sample line identified a new 550-metre-long gold anomaly located 1 km east of the main Swan zone anomaly. Assaying of soil samples yielded values up to 268 ppb Au within this new anomaly.

First-pass prospecting was conducted on a ridge 2 km west of the Swan zone, across the valley from where the historic diamond drilling was conducted. Multiple new quartz-arsenopyrite showings were identified, and assays returned values up to 0.79 g/t Au.
