Seal Zinc and Silver Deposit

The Seal Project is located within the Storm Project claims, at the northern end of a regionally extensive zinc horizon. The Seal Deposit has been linked to the same mineralisation event that formed the nearby Polaris Zinc-Lead Deposit (22Mt @14.1% Zn, 4% Pb).


At Seal, stratabound Mississippi Valley type zinc and silver mineralisation has been discovered with historical intercepts including:

  • 14.4m @ 10.58% Zn, 28.7g/t Ag from 51.8m
  • 16m @ 6.62% Zn, 27.1g/t Ag from 76.6m
  • 22.3m @ 23% Zn, 5.1g/t Ag from 101.5m
  • 2.4m @ 15.13% Zn, 91.9g/t Ag from 133.5m

These discoveries are hosted within a mineralised sequence that has a strike length of approximately 80km. Less than 5% of the mineralised trend has been tested by drilling, providing an opportunity for American West to potentially extend the footprint of mineralisation through further exploration.

Existing Resource

Aston Bay announced an initial resource for Seal in its Technical Report of January 17, 2018 issued in compliance with NI 43-101. The resource estimate is 1Mt @ 10.24% Zn46.5g/t Ag for 103kt Zn1.5Moz Ag.

Widespread zinc soil anomalies, including the Typhoon Zinc Prospect, have been identified along the extensive prospective horizon.

American West believes these targets provide the potential for additional discoveries of further high-grade zinc and silver deposits within the Project area.
