Deposit Type

  • Magmatic


Summary:

There are in the Lac Allard area six ilmenite deposits. The largest and most important is the Lac Tio deposit. The deposits of the Lac Allard region contain ilmenites of similar composition.

The Allard Lake ilmenite deposits lie in the northeastern part of one of the large Precambrian anorthosite masses and comprise a series of metamorphic and igneous rocks that belong to the Grenville Province. The ore bodies consist of a series of narrow dikes, irregular lenses, or sill-like bodies that appear to be genetically related to the anorthosite rocks in which they occur.

Rocks of the "Grenville Series" are represented by quartzites, quartz-biotite gneiss, quartz-hornblende gneiss, garnetiferous gneiss, and small patches o: amphibolite and garnetiferous graphite schist. These rocks occur abundantly along the Romaine River between the First East branch and the Second East branch. Numerous outcrops are also found on the shores of Forget lake and in the adjoining area to the east.

The most important lithological unit in the Lac Allard region is anorthosite and related rocks.

Anorthosite is the major rock type in the vicinity of Lac Allard. As a rule, it is massive, coarse-grained and contains 95 percent or more plagioclase. In fresh exposure, it varies in color from pale gray to pink to somewhat resinous green when it contains more than 5 percent ferromagnesian minerals. In weathered outcrops, the anorthosite is usually gray to chalky whit ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Mine at Lac Tio is located 43 kilometres north-east of Havre-Saint-Pierre on the largest solid ilmenite deposit in the world. Mineral resources include Tip and Beaver deposits.

Ore from Tio deposit is already mined via conventional open pit truck and shovel operation.

The Beaver deposit will be mined similarly to the Tio mine applying a similar bench height (11 m), pit slope and ramp width to the Tio mine. The main ramp is designed assuming the use of Caterpillar 777 trucks in accordance with local mining regulations.
