Mine Life12 years (as of Jan 1, 2016)
The Ootsa project (Seel and Ox porphyry deposits plus Seel Breccia Zone(s)) has been advanced through extensive resource drilling and metallurgical test programs.

2016 PEA outlined integration scenario with neighbouring Huckleberry mine highlighting lowcapex opportunity to extend operating life of existing infrastructure.

Updated 2022 resource demonstrates significant metal endowment and ongoing expansion potential of nearsurface zones.

Deposit Type

  • Porphyry


Summary:

The Ootsa Project, as made up of both the Seel and Ox Deposits lie in a highly prospective area and represent several porphyry deposits alongside numerous other exploration targets across the property.

The Seel and Ox deposits contain disseminated and veinlet controlled Cu-Au-Mo-Ag mineralization and large zones of potassic, sericitic, chlorite-bearing, and argillic alteration assemblage consistent with classification as a porphyry Cu system. Late base metal silver veins at the Seel Breccia and Damascus areas share characteristics with base metal Ag veins known to occur around porphyry deposits.

The Seel deposits can be separated into four domains; East Seel, West Seel, Seel Breccia and the East Extension Zone (also called NE zone).

The East Seel Cu-Au zone
East Seel Cu-Au style porphyry mineralization is associated with early potassic alteration and quartz- chalcopyrite-magnetite-pyrite veining with a moderate to strong chloritic component. This style of mineralization forms a distinct airborne magnetic high. The main intrusive unit throughout the Cu-Au zone is a coarse crowded porphyry containing 40 to 60% phenocrysts in a fine grained aphanitic matrix. Feldspar is the dominant phenocryst consisting of euhedral and sub rounded crystals, 3 to 7mm in size. Biotite phenocrysts, 2 to 3mm in size make up about 2 to 5% of the rock but are often completely masked by alteration. This rock is termed “crowded feldspar porphyry” as the feldspar p ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The deposits at the Ootsa Property will be mined by conventional truck/shovel open pit methods. Mill feed will be transferred from Ootsa to the mill via a conveyor system. Combined mill feed, waste and overburden mining will be conducted over a period of 12 years at a nominal average rate of 40,000 tpd to supply 5.6 Mt of feed annually at a strip ratio of 1.46:1. Three open pits will be mined in sequence starting with East Seel, then Ox, and finally West Seel. The sequence follows the highest value of the mineralized material, which is primarily a function of grade and strip ratio to maximize Net Present Value (“NPV”).

A geotechnical review of the Seel and Ox deposits was conducted to establish pit slope parameters for mine design. Recommended pit slope angles for the Seel deposit in hard rock were 70o bench face angles, 53 degrees inter-ramp angles, and 41-48 degrees overall slope angles depending on the placement of ramps and presence of overburden in highwalls. Recommended pit slope design parameters for Ox in hard rock were 65o bench face angles, 45 degrees inter-ramp angles, and 43 degrees overall slope angles.

Mining will be conducted by a mining contractor that will provide its own equipment fleet and will operate the mill feed conveyor system. The mobile mine equipment fleet has been specified based on the equipment at the HB Mine which could be available for use at the time Ootsa is developed. There is, however, no necessity to use the same type ........
