Idaho Gold Project: The Friday Zone
The Friday Zone is centered at Orogrande Mining district, approximately 16 km southwest of Elk City and is about a 5 hours to the south of Spokane. This project has direct access to the State Highway 14 from Grangeville, located 60 miles west of the Elk City.
The Friday mineralization consists of native gold, electrum, pyrite, weak arsenopyrite, galena, sphalerite, chalcopyrite, and molybdenite; while the Petsite stock mineralization consists of gold-silver-arsenic, with gold, electrum and unidentified tellurium minerals.
District Exploration & Development Potential:
There are many undrilled targets left in the area around the Friday Zone, as well as, in the remainder of the 28-km-long Orogrande Shear Zone, indicating large upside potential for AmeriWest’s Idaho Gold Project.

All the holes intersected gold mineralization in excess of 1g/t; the best intercepts being in two holes, 4.6 g/t over 29.3 m (including 8.95 g/t over 4.5 m)
and 3.03 g/t over 27.9 m.
The gold recoveries on thirteen samples from the Friday deposit ranged from 75.2% – 93.8% averaging 86.2%. e silver recoveries, ranged from 17.0% to 80.6% with an average of 49%.
The assayed (direct) gold head grades ranged from 0.35 g/t – 5.92 g/t Au and the calculated gold head grades (from the cyanide leach metallurgical balance) ranged from 0.28 g/t – 9.07 g/t Au.
Due to the reliance on legacy data dating back to 1996, the results above are considered historic and cannot be relied upon under NI 43-101 standards. For the same reason, no part of the estimated resource was classified as ‘Measured’.

- Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability
- Mineral resources are amenable to open pit mining methods and have been constrained using a Lerches-Grossmann optimized pit.
- Assumptions include US$1,500/oz Au, 85% Au recovery, $2.50/tonne mining cost, $2.00/tonne waste mining cost, $12.00/tonne process and G&A cost. No allowances have been made for mining losses and dilution. Pit slope angle of 45°.
- The base case gold cut-off (bolded) is greater than the conceptual marginal cut-off of 0.36 g/t. The Company has elected to use a 0.45g/t cut-off.
- Gold analyses are performed by fire assay/AA finish methods
