Located in the historic Fortymile placer district, the Napoleon Project encompasses a high-grade quartz vein lode gold system. The hard rock source of much of the Fortymile placer district is believed to be sourced from the Napoleon area as the project straddles the highlands which feed the most productive gold bearing creeks.
Emplacement et accès
The Napoleon project covers 6065 hectares of state owned Alaska mining claims and is located 15 km northeast of the town of Chicken or 140 km from Tok, Alaska along the seasonal Taylor Highway. The property is road accessible via the Taylor Highway with a network of four-wheel-drive tracks along the ridge tops throughout much of the project area.
Géologie et minéralisation
The property is located within Alaska’s historic Forty Mile Mining District, which is part of the prolific Tintina Gold Province; host of significant deposits such as Donlin Creek, Fort Knox, Pogo, Coffee, Sheelite Dome and Dublin Gulch. Gold mineralization at Napoleon is hosted in high-grade quartz veins, related to a regional shear zone which intersects the Jurassic aged Napoleon pluton. Gold mineralization is controlled by east-west and northwest trending shear zones within the Napoleon pluton, commonly kaolinite-quartz-carbonate altered. High-grade gold is associated with quartz-pyrite veins, with K-feldspar-sericite-pyrite altered selvedges.
Histoire de l’exploration
The property was first staked by Kennecott in 1998 following regional compilation work which identified anomalous gold-in-stream-sediment samples reported by Phillips Petroleum in a 1982 report. Kennecott carried out grid soil sampling over areas of known mineralization and regional ridge and spur soil sampling and infill stream sampling throughout the property. Between the 1998 and 1999 field seasons; soil sampling, prospecting, airborne and ground geophysics, and the excavation of 25 shallow trenches led to the discovery of five target areas: Main Zone, Saddle Zone, Trench 24 area, Twin Peaks and Burnt Ridge. Kennecott drilled 6 diamond drill holes and 10 reverse circulation holes and reported gold intercepts over 1.0 ppm in 8 of the 16 holes, with the best intercepts being 0.61m @ 34.71 g/t Au and 0.61m @ 14.74 g/t Au in the Main Zone, and 1.52m @ 6.56 g/t Au at Burnt Ridge.
The Napoleon property was explored by Tech Resources between 2000 and 2001 which included grid construction, a ground magnetic and induced polarization (IP) geophysical surveys, soil and rock sampling. This work was subsequently followed up with 11 diamond drill holes, returning 0.90m @ 20.59 g.t Au at Twin Peaks, and 3.00m @ 8.49 g/t Au at the Saddle Zone.
Between 2007 and 2009 Millrock Resources Inc. staked the Napoleon property and conducted additional soil and rock sampling along with a review and evaluation of existing data to generate additional drill targets. Millrock did not conduct any drilling on the property and the ground was eventually relinquished.
Northway Resources Corp. (Northway) acquired the Napoleon property in 2019 through staking based on internal state wide compilation and review of available data. Exploration activities conducted by Northway in 2020 include a ground based magnetometer and very low frequency electromagnetic (VLF-EM) survey and infill C-horizon soil sampling over the main target areas to help define drill ready targets.
