Jefferson Canyon

    • Contains a large volcanic-hosted epithermal Au-Ag system
    • Same age as the nearby Round Mountain deposit (7.5km west), which is a world-class low-sulfidation (LS) epithermal deposit (>17M oz. Au)
    • Both are hosted in felsic ash-flow tuffs along the margins of calderas and both contain a strong northwest-trending structural control to veins
    • Extensive Au-Ag mineralization over 1.4 X 1.8 km with coincident QSP alteration and supporting geophysics
    • Drill hole GJ81 returned an impressive 41.2m of 6.4 g/t Au and 402 g/t Ag, including 1.5m of 88.7 g/t Au and 2021.7 g/t Ag  (CR Exploration Co., 1985)
    • Expansion potential is very good

The Plan

    • Compilation and modeling of large amount of legacy data
    • Detailed mapping and sampling (rock & soil) of strong gold-in-rock anomalies identified by Aura in 2019
    • Permitting
    • Drilling and additional soils-rock geochemistry

Internal block model for the Jefferson Canyon Project (Non-NI-43-101 Compliant)

Gold79 has generated an internal (non-compliant under CIM standards) block model of mineralization for the Jefferson Canyon project (Figure 2). The block model was calculated based on 118 historical holes totaling 18,106 metres. The Company does not currently have rock density measurements for Jefferson Canyon core. Rock density of 2.3 grams per cubic centimetre was used given that Jefferson Canyon shares many geological similarities with the neighboring Round Mountain deposit

Disclaimer: Figure and Table provided above represent a preliminary internal mineral resource estimate for the Jefferson Canyon project that is only intended for informational purposes. The resource is non-compliant under CIM NI-43-101 reporting standards and the stated figures cannot be relied upon. Gold79 does not treat this as a current mineral resource estimate and there are no assurances that it could be achieved.
