Property Delbreuil

Location

The Delbreuil Canton is situated in the Pontiac subprovince between Lac Nodier and Lac Simard, north-east of Winneway in the Abitibi-Temiscamingue region. Access is fairly easy due to a number of trails maintained for ATV and snowmobile usage.

Geology and mineralization

A detailed mapping study has been conducted in the Delbreuil Canton, which is situated in the Pontiac subprovince northeast of Winneway in the Abitibi-Temiscarningue region.
Delbreuil is comprised of several units which can be subdivided into: 
  1. Supracrustal rocks: 
    • komatiite flows,
    • volcanoclastics sediments and sediments (e.g. tuffite),
    • sediments,
    • and d) basalt; 
  2. Intrusive rocks:
    • Granite and pegmatite,
    • monzodiorite,
    • monzonite,
    • magmatic breccia,
    • gabbro, and
    • dykes; 
  3. High-grade (basement) metamorphic rocks:
    • biotite schist,
    • biotite-amphibolite schist,
    • white mica-amphibolite schist,
    • amphibolite, and
    • gneiss. 
All the rocks in Delbreuil have undergone metamorphism and the structures of Delbreuil are complex. Folding and shearing are evident throughout the Delbreuil area, and there is a general northwest-southeast trend of the major structures.

Fine-grained disseminated sulfides are common throughout Delbreuil and can be found in almost all the rock units. Generally the sulfides compose < 5% of the rock. The most common sulfides found in Delbreuil are pyrite and pyrrhotite. Pegmatites containing molybdenite and lepidolite also occur. Komatiites of Delbreuil are flanking flows of a distal-lateralflow discharge lobate flow facies, and not a preferred lava pathway. However, the flows may be basal and could warrant further study since most economic mineral deposits in komatiites are located at the base of komatiite flows. Also, primary mineralization of the flanking flows may indicate that there is mineralization in the preferred lava pathway. Geochemical and polished thin section analyses may offer fiuther support for the continued exploration of the surrounding Delbreuil area. It is recommended based on field observations such as flow direction of the komatiites and younging directions that fbrther exploration should take place southeast and east of Delbreuil
