Macks, YT
Highlights
- 71 km2 property located 42 km south of Carmacks
- Located 10 km from the all-season Klondike Highway and powerline, with a historical trail from the highway to site
- Prospecting has returned high-grade rock samples including 3.31% copper, with 1.23 g/t gold and 90.60 g/t silver
- Newly discovered 2.2 km x 2 km copper-molybdenum soil anomaly coincident with a regional 1.2 x 1.2 km magnetic low
Macks Geology & Mineralization
The 71 km2 Macks Property was staked by Cascadia in 2023. It is located 43 km south of Carmacks within the traditional territory of the Little Salmon Carmacks, Champagne and Aishihik, and Kwanlin Dun First Nations. The property is 10 km from an all-season highway and powerline and is currently accessed by helicopter. An overgrown bulldozer trail to the property exists; which could potentially be used in future exploration programs.
Work at the Macks property has identified a 2,200 by 2,000 m copper ± molybdenum soil anomaly which remains open to the west; associated with a magnetic low response in regional government geophysics. Prospecting samples from this area returned elevated copper, gold and molybdenum. A chip sample from a magnetite skarn outcrop in this area returned 0.49% copper with 0.12 g/t gold and 4.7 g/t silver over 1.50 m, contiguous with a chip sample which returned 0.25% copper with 3.0 g/t silver and 265 ppm molybdenum over 1.65 m.
A bedrock chip sample from a magnetite skarn near a historical anomaly in the southeast portion of the property returned 1.20% copper with 2.26 g/t gold and 68.3 g/t silver over 2.00 m, contiguous with a chip sample which returned 0.23% copper with 0.44 g/t gold and 20.9 g/t silver over a further 2.00 m. These samples are located within a 1,500 m x 1,000 m copper ± gold soil anomaly.
The property lies within the Stikine Terrane and is adjacent to the 200 km dextral strike slip Braeburn fault. The Stikine Terrane is characterized by Late Triassic to early Jurassic volcanic-plutonic arc complexes that are well-endowed with copper-gold-molybdenum porphyries including the Red Chris, Schaft Creek, Kemess, KSM and Galore Creek deposits and mines.
The property is dominantly underlain by the Upper Triassic aged Povoas Formation andesites and basalts of the Lewes River Group which have been intruded by the Early Jurassic aged Aishihik Batholith granitoid of the Long Lake Group.
The area has been historically explored for high grade copper skarn mineralization and demonstrates potential for Cu-Au-Mo porphyry mineralization. Much of the Macks Property has yet to see systematic prospecting and mapping, with previous exploration only documented in the southeast corner nearby a historical adit.
