Deposit Type

  • Iron formation hosted


Summary:

The Scully Deposit mineralization style is a deposit typical of the Superior-Lake type of Iron Formations.

The Scully Mine lies within the Labrador Trough in Western Labrador. The Sokoman Formation is an iron formation that consists of three (3) iron bearing formations, named the Upper, Middle and Lower Iron Formations. The Sokoman Formation is more than 300 m thick near the Scully Mine and has been subjected to two (2) episodes of folding and metamorphism during the Hudsonian and Grenville orogenies, resulting in a complex structural pattern in the Wabush Area. The younger Menihek and Shabagamo Formations and the older Denault, Attikamagen, and Wishart Formations all outcrop in the vicinity of the mine site. The mineral deposit that defines the Scully Mine consists of folded and faulted stratigraphic beds of iron-bearing units within the regional Sokoman Iron Formation.

Mineralization
The ore minerals are hematite (specularite), magnetite, and martite. The waste minerals are quartz and hydrated iron oxides such as limonite and goethite. Manganese oxides also occur in bands or are disseminated throughout the iron-bearing units.

All units are overlain unconformably by glacial till (overburden) and underlying the Lower Member is a silicate-rich iron formation known as the Basal Silicates (considered the footwall waste unit). Unfolded, the average thickness of the formation is about 800 feet. Each member is split up into separate numeric su ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Tacora Resources Inc. (“Tacora”) has been in production at the site since June of 2019.

The operation consists of a conventional surface mining method using an owner mining approach with electric and diesel hydraulic shovels, mine trucks and electric drills. Tacora had purchased the loading and drilling fleet in anticipation of the mine restart.

Producing a LOM plan targets a production rate of about 6 Mtpy of iron ore concentrate with a crude ore feed to the concentrator averaging 18 Mtpy or about 3 Mtpy per grinding line.

Mine Designs
The open pit area measures approximately 5.4 km in the east-west direction and 2.1 km in the north-south direction. Mining of the Tacora open pit is planned with three distinct pits: Boot Pit, Center Pit and East Pit. The Center Pit is further divided into three stand-alone sub-pits / sectors: Center Pit West, Center Pit South, and Center Pit East. All Pits contain varying degrees of historical mining. Currently, mining is taking place in the Boot Pit and Center Pit West.

The final design pit contains 477.9 Mt of ore at an average grade of 34.88% Fe, 2.61% Mn and 5.54% SAT. This mineral reserve is sufficient for a 27-year mine life with possibilities for expansion at higher iron ore prices and with the conversion of inferred resources to measured and indicated resources. A total of 868.8 Mt of ore and waste is to be mined for an overall strip ratio of 0.82:1.

The batter angles vary f ........
