Summary:

The Lac Doré Complex is a lopolith, a sub-tabular intrusive body of mafic to anorthositic composition, strongly differentiated near its top. The lopolith is emplaced within the Waconichi Formation, a felsic volcanic and sedimentary pile, and folded along by the regional anticlinorium. The deposit is hosted in a homoclinal sequence of magnetite bearing layers within the South flank of the Lac Doré Anorthositic Complex. Top of stratigraphy is to the south.

According to Allard (1967), the Lac Doré Complex is divided in four major units. From top to bottom they are:
- The border zone (top, South-East);
- The granophyre;
- The layered zone;
- The Anorthositic zone (base, North-West).

The layered zone hosts the vanadiferous titanomagnetite deposit, while the anorthosite and the granophyre host most of copper-gold mineralization of the mining camp (outside the current project). The anorthosite zone (approximately 3660 m in observed thickness) is composed of anorthosite, gabbro and titanomagnetite-bearing gabbro, plus some minor pyroxenite. The titanomagnetite abundance as well as the vanadium content increase in the upper 150 metres of the unit, toward the layered zone.

The layered zone, which hosts the vanadiferous titanomagnetite deposit, consists up of 450 to 900 metres of rhythmically layered beds rich in pyroxene, titanomagnetite plus ilmenite, intercalated with layers of anorthositic gabbro. The vanadium mineralization is lo ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Lac Doré deposit is located at surface, on an elongated hill crest, suitable for conventional open pit mining methods. As only inferred resources are available designing an elaborate mining plan following the Whittle model would be premature. Upgrading of the inferred resource through systematic drilling is recommended prior to designing a Wittle shell model.

The summit of the deposit is located at an altitude of 530 metres above sea level (asl), approximately 80 metres higher than the lowland at 440 metres asl where the mill is anticipated to be located. A saddle along the hillcrest is located between East and West deposits, which can be used as a lateral outlet from the pits to the mill. Thus, the East and West deposits can be mined in the manner of two front-faced quarries, limiting the need for ramps and limiting the up-hill climb for the hauling trucks.

The deposit extends for 2400 metres within VanadiumCorp property. The pit will be limited to the Northeast by the limit of the known mineralization with sufficient thickness, and to the Southwest by BlackRock Metals CDC-2430231. There is no hindrance to the lateral extend of the pit.
