The 330 km2 Goliath Gold Complex demonstrates numerous highly prospective targets that show potential to host gold mineralization including about 65-kilomtre prospective strike along trend from the Goliath, Goldlund and Miller deposits.
Goliath is in the Wabigoon Subprovince of the Archaean Superior Province, north of the Wabigoon Fault. An amphibolite metamorphic grade volcanogenic-sedimentary complex topped by an upper layer of greenschist characterizes much of the project area. The assemblage itself comprises quartz-porphyritic felsic to intermediate metavolcanic rocks represented by biotite gneiss, mica schist, quartz-porphyritic mica schist, a variety of metasedimentary rocks and minor amphibolites. Compositional layering in metasedimentary rocks strikes ~70 degrees to 90 degrees and dips from 70 degrees to 80 degrees south-southeast. The Thunder River Mafic Metavolcanics underlie the south part of the Property. All the rocks have been subject to folding and moderate to intense shearing with local hydrothermal alteration, quartz veining and sulphide mineralization.
The main zones of mineralization of the Goliath Deposit consist of the Main Zone, Footwall Zone (B,C and D subzones), and Hangingwall Zone (H and H1 subzones). Mineralized zones strike approximately east-west and dip 70 degrees - 80 degrees to the south-southeast.
The mineralized zones are tabular composite units characterized by anomalous to strongly elevated gold concentrations, increased lead and zinc sulphide content and distinctive altered rock units. Stratigraphically, gold mineralization is contained in an approximately 100- to 150-metre wide central zone composed of intensely altered felsic metavolcanic rocks (quartz-sericite and biotite-muscovite schist) with minor metasedimentary rocks. Overlying hanging wall rocks consist of altered felsic metavolcanics (sericite schist, biotite-muscoviteschist and metasedimentary rocks), with the footwall comprising metasedimentary rocks with minor porphyries, felsic gneiss and schist. Gold within the central unit is concentrated in a pyritic alteration zone, consisting of quartz-sericite schist (MSS), quartz-eye gneiss and quartz-feldspar gneiss.
High-grade gold mineralization (>3 g/tonne) is concentrated in several steeply dipping, west-plunging shoots with strike lengths (over 50 metres) and significant down-plunge continuity. The high-grade shoots are interpreted to be the result of the intersection between tight F1 isoclinal folding of the mineralized horizon and regional F2 folding with gold often concentrated in fold noses. These high-grade “shoots”, which appear to occur in regular intervals, are separated by lower grade Au/Ag mineralized rocks.
The Wabigoon Subprovince is now host to several multi-million ounce, NI 43-101 compliant mineral resources.
