Summary:
The Maverick Project occurs at the boundary of the Kisseynew and Flin Flon domains. This complex boundary zone is comprised of structurally interleaved supracrustal rocks of the Flin Flon Domain and high-grade metamorphic gneisses of the Kisseynew Domain. The Project area is underlain by strongly deformed and metamorphosed para- and orthogneisses. The protoliths of the gneisses are interpreted to be supracrustal rocks of the Amisk Group, metasedimentary rocks of the Missi and Burntwood groups, and gneissose intermediate to felsic intrusives.
Maverick Project consists of the non-contiguous PL and Nokomis Properties.
PL Deposit
Gold mineralization at the PL Deposit is concentrated along the flexure in the duplex structure and the southeastern strike-extent of the D3 shear zones over a strike length of 1,200 m. The mineralization is controlled by four main shear zones that delineate the duplex structure and are named the Sherridon, Upper, Main, and Lower Zones. The shear zones and contained mineralization subcrop, under a northwest-southeast-trending swamp (i.e., Fyre Lake), have been outlined by surface diamond drilling to a vertical depth of 500 m, approximately 1,200 m down dip. The Upper, Main, and Lower Zones occur within 50 m of the sheared tonalite contact and toward the north end of the deposit, the Lower Zone is commonly hosted within the tonalite body.
The gold-bearing shear zones generally strike 330 degree and dip moderately at 30 degree to the northeast, subparallel to the regional foliation.The mineralized zones occur in 1.3 2.5 m wide shear zones that contain variable amounts of quartz veins. The quartz veins form as 1.5 cm to >1.0 m wide fault fill veins and tension vein arrays. The average thickness of the quartz veins is 25-35 cm. The fault fill veins are generally concordant with the regional foliation, but locally crosscut it. The veins exhibit crack-seal textures and are primarily composed of white quartz. Often, the white quartz is crosscut by a younger phase of translucent quartz that is associated with higher abundance of galena, chalcopyrite, and visible gold. The tension vein arrays have been rotated into masses of white quartz during progressive deformation within the shear zone. The best developed intervals of quartz veins often occur near the contact between metagraywacke and tuffaceous metavolcanics units. This is interpreted to indicate that competency contrast is an important control on the formation of quartz veins and associated gold mineralization.
Sulphide mineralization within the shear zones occurs as halos of replacement mineralization around the quartz and in the quartz veins. The assemblage of sulphides is primarily comprised of arsenopyrite pyrrhotite-pyrite. Trace amounts of galena-chalcopyrite-sphalerite are also present. Visible gold occurs throughout the deposit, but is not common. Arsenopyrite is ubiquitous in the gold-bearing zones occurring as trace to 2%, fine to medium grained disseminations within the host rocks and more importantly, from trace to +5%, associated with the quartz veins, especially along the margins of the veins and along chloritic fractures/slips, or associated with incorporated rafts of the foliated and mineralized wall rock. In general, higher gold grades are associated with increased arsenopyrite content.
Nokomis Deposit
At the Nokomis Deposit, gold mineralization occurs within a shear zone cutting a differentiated gabbroic sill emplaced near the contact between the metasediments of the Nokomis group and mafic volcanics of the Amisk Lake group. The host unit for the gold mineralization has been described as a ferrotonalite to diorite. Alteration includes silicification, carbonatization, and albitization.
The Nokomis Deposit is made up of the mineralized Upper and Lower Host Zones that have been separated by a steeply dipping normal fault that is intruded by pegmatite.
