Deposit Type

  • Banded iron formation


Summary:

The Trough, otherwise known as the Labrador Quebec Fold Belt, extends for more than 1,100 km along the eastern margin of the Superior Craton from Ungava Bay to Lake Pletipi, Quebec. The belt is about 100 km wide in its central part and narrows considerably to the north and south. Adriana’s Property is located north of the Grenville Front in the Churchill Province where the Trough rocks have been subject to greenschist or subgreenschist grade metamorphism and the principal iron formation unit is known as the Sokoman Formation. The lithological units of interest on the Property due to their iron content are members of the Sokoman.

The Lac Otelnuk deposits are composed of iron formations of the Lake Superior-type. This type of iron formation consists of banded sedimentary rocks composed principally of bands of magnetite and hematite within quartz (chert)-rich rock, with variable amounts of silicate, carbonate and sulphide lithofacies. Such iron formations have been the principal sources of iron throughout the world. Lithofacies that are not highly metamorphosed or altered by weathering are referred to as taconite and the Lac Otelnuk deposits are examples of this type.

Mineralization in the iron formation consists mainly of magnetite (Fe3O4) and hematite (Fe2O3), however, some iron also occurs in siderite and ferro-ankerite. Iron oxide bands containing concentrations of magnetite and/or hematite alternate with grey chert of jasper.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The mining method selected for the Project is a conventional open pit consisting of drilling and blasting and a truck and shovel operation with a designed bench height of 15 m. Trees will be cleared prior to the start of mining Next, a mining contractor will remove the topsoil and overburden using a fleet of dozers, excavators and haul trucks. The ore and waste rock will be drilled, blasted, and then loaded with large mining shovels into a fleet of rigid frame trucks which will haul the material either to the primary crushers, the low grade stockpiles, or the mine rock piles (for the waste rock).

The mining operations for the Project will be 365 days per year, operating around the clock on two (2) 12-hour shifts. A total of five (5) days per year have been accounted for when the mine will be shut down due to severe weather conditions. During these periods, the primary crushers will be fed from the run of mine ore stockpiles using front end wheel loaders.

A mine plan was developed for the 30-year life of the open pit which follows the phased approach of the Feasibility Study, producing 30 Mt/y of concentrate in Phase 1 and 50 Mt/y of concentrate in Phase 2. One of the goals of the mine plan is to ensure that several different ore types are always in production in order to avoid fluctuations in grade and hardness. Blending of the different ores will occur at the primary crushers as trucks arrive from different shovels that are mining the dif ........
