Lalor Deposit Claim Area

 mine  Add category

This is the claim area for the Lalor zinc/gold/copper deposit. HudBay Minerals owns 100% of the Lalor Deposit which was discovered in 2007. The project is believed to hold the second-largest metal deposit in the Flin Flon Greenstone Belt and the largest pre-development deposit discovered in the Flin Flon-Snow Lake region. The property consists of five mineral claims and eight Order in Council Leases to the south. The mineral claims consist of: CB5361, DUB 10605, DUB 10606, DUB 10607, DUB 10608. The order in council leases consist of: OX 143, OX 144, OX 145, OX 146, OX 153, OX 154, OX 155, OX 156.

The Lalor property lies in the eastern (Snow Lake) portion of the Paleoproterozoic Flin Flon Greenstone Belt and is overlain by a thin veneer of Pleistocene glacial/fluvial sediments. Located within the Trans-Hudson Orogen, the Flin Flon Greenstone Belt
consists of a variety of distinct 1.92 to 1.87Ga tectonostratigraphic assemblages including juvenile arc, back-arc, ocean-floor and ocean-island and evolved volcanic arc assemblages that were amalgamated to form an accretionary collage (named the Amisk Collage) prior to the emplacement of voluminous intermediate to granitoid plutons and generally subsequent deformation (Syme et al., 1998).

The volcanic assemblages consist of mafic to felsic volcanic rocks with intercalated volcanogenic sedimentary rocks. The younger plutons and coeval successor arc volcanics, volcaniclastic, and sedimentary successor basin rocks include the older, largely marine turbidites of the Burntwood Group and the terrestrial metasedimentary sequences of the Missi Group.

The Flin Flon belt is in fault and /or gradational contact with the Kisseynew Domain metasedimentary gneisses to the north and is unconformably overlain by the Phanerozoic cover of sandstone and dolostones to the south. Regional metamorphism at 1.82 to 1.81Ga formed mineral assemblages in the Flin Flon belt that range from prehnitepumpellyite to middle amphibolite facies in the east and upper amphibolite facies in the north and west (David and Machado, 1996; Froese and Moore, 1980; Syme et al., 1998).
