Name: NICO mine.

Location: The NICO deposit is located in Canada’s Northwest Territories (NT), about 160 km north-west of Yellowknife, 50 km north-east of the community of Whati and 85 km north of the highway to Edmonton, Alberta.

Controlling Company: Fortune Minerals (100%).

Brief History: Fortune Minerals discovered the NICO deposit in 1996 and has invested C$100-million in the project to date. This includes drill delineation of the 33-million-ton reserve, underground test mining to verify the geometry and grade of the deposit, the collection of bulk samples to conduct metallurgical test work, pilot plant testing to confirm the process flow sheet, verification of the production of high-value metal products and the improvement of process recoveries. NICO has been assessed in a positive bankable feasibility study and in 2012 the company released a front-end engineering and design study for procurement and to confirm economics.

Brief Description: The NICO property consists of ten mining leases, covering an estimated 5 140 ha. The mine will be a vertically integrated project and will include mining and concentrating facilities in the NT to produce a bulk sulphide concentrate. This concentrate will be transported by truck and rail to the company’s proposed refinery, in Saskatchewan, for further processing to high-valued metal products. The refinery lands straddle the Canadian National Railway 27 km north-west of the city of Saskatoon.

 

Mining Method: NICO will be mined primarily by openpit methods, with underground mining also contributing mill feed during the first two years of operations. The openpit section will be a conventional truck-and-shovel/loader operation. The underground section will use retreat blasthole open stoping methods, using a contractor.

Products: Gold doré, cobalt metal and/or cobalt sulphate, bismuth ingot and copper precipitate.

 

Major Infrastructure and Equipment: The NICO site will have an openpit and underground mine to feed a 4 650 t/d mill with crushing, grinding and flotation facilities. There will also be a truck shop/warehouse/office complex; a fuel storage facility; a camp to accommodate up to 250 workers; a 10 MW diesel electrical plant, with heat recovery; and a comingled tails and mine rock storage area.

The refinery in Saskatchewan is a proposed hydrometallurgical facility, with regrind and secondary flotation facilities; an autoclave and solvent extraction plant for cobalt and copper recovery; acid-leach, electrowinning and smelting facilities for bismuth; and cyanide leaching facilities for the recovery of gold. Ancillary facilities will include an oxygen plant, an office and warehousing, rail siding and residue storage.

Geology/Mineralisation: NICO is an iron oxide copper/gold class deposit, with mineralisation hosted in brecciated clastic sedimentary rocks of the Treasure Island group. The deposit occurs near the unconformity, with overlying felsic volcanic rocks of the Faber group. The sedimentary and volcanic rocks are intruded by feldspar +/- quartz +/- amphibole porphyritic felsic dykes that are broadly coeval with and related to the Faber group volcanics.

Ore is contained in a series of 40º north-dipping stacked stratabound lenses of ironstone. The main mineralised lenses are referred to as the Upper, Middle and Lower zones, which are up to 1.5 km in length, 550 m in width (down dip) and 70 m in thickness (across dip).

The host sedimentary rocks in the vicinity of the ore zones have been extensively hydrothermally altered to biotite-amphibole-iron oxide ironstones and schists. Ore is associated with the estimated 5% disseminated and fracture-filling sulphide fraction. The minerals of economic interest are primarily native gold, cobaltian arsenopyrite, cobaltite, bismuthinite, native bismuth and chalcopyrite.

Reserves: Total proven and probable reserves as at July 2012, were 32.988-million tons, with a grade of 1.02 g/t gold, 0.11% cobalt, 0.14% bismuth and 0.04% copper.

Prospects: The Mackenzie Valley Review Board concluded its
environ- mental assessment of the proposed NICO mine and mill in January and recommended the approval of the project, subject to the measures set out in its report. Concurrent with the permitting process, Fortune has been working with Deloitte & Touche Corporate Finance Canada to attract one or more strategic partners to provide project financing for the mine and mill, in the NT, and the refinery, in Saskatchewan. Discussions are ongoing with several parties interested in joint venture development.
