The Point Rousse Complex is host to orogenic-style gold mineralization. Mineralization comprises both vein-hosted and altered-wall rock or replacement styles of mineralization and both exhibit features common to orogenic gold deposits. The mineralization is typically structurally controlled and developed within subsidiary deformation zones, such as the Scrape Trust Fault, to major regional structures, like the Baie Verte – Brompton Line fault. gold mineralization is intimately associated with disseminated and massive pyrite within the host rock indicating that iron rich rocks are an important precursor to mineralization. Alteration within mafic volcanic and gabbroic rocks can be is characterized by albitization and carbonitization. Iron and titanium rich lithologies associated with the Scrape Thrust are typical host rocks.

The Point Rousse gold mineralization exhibits relatively narrow, but distinctive alteration haloes dominated by Fe-carbonate, albite, sericite, chlorite and leucoxene (Plate 9). The ore mineralogy is relatively simple and is generally comprised of non-refractory gold either as free gold or as coatings on, or along fractures/grain boundariesin pyrite. Silver and base metals can be present in minor amounts and the deposits typically exhibit only trace arsenic.

D3 deformation produced F3 mesoscopic northward-verging asymmetric folds that affect all the D1/D2 fabrics, shear zones and related alteration. The F3 folds trend roughly southeast ........

Development of two open pits at Stog’er Tight were completed in 2019 shows the pit design specifications used at the East and West Pits. A total of 338,818 tonnes were milled from the east and west pits recovering 17,054 ounces of gold at an average recovered grade of 1.57 g/t gold. The Stog’er Tight East and West pits are currently under closure activities as per the accepted closure plan with the Department of Natural Resources – Mines Branch. Not yet developed are two satellite pits: the north and south pits. It should be noted that these two pits are currently in the process of being scheduled, as there is existing exploration in this area which could impact development.

The Stog’er Tight development is proceeding with Development, Rehabilitation and Closure plans and an Environmental Registration Document to be submitted to the provincial Departments of Industry, Energy and Technology and the Department of Environment and Climate Change in Q4 of 2021. Additional certificates and approvals for the Stog’er Tight development are anticipated prior to the completion of mining at Argyle.

Future recommended work at Point Rousse includes the following:

• Calculate Mineral Reserves for the Stog’er Tight Deposit and create a development plan that provides material to the Pine Cove Mill in Q4 2022;

• Continue development and permitting work to develop the Stog’er Tight Mine to extend the life of mine at Point Rousse.

Ore is fed to the crushing plant via front end loader, where it first enters a jaw crusher. After crushing, a conveyor takes the ore to a screen deck, where the fine material is separated. Oversize ore is recirculated through a cone crusher until it reaches the desired top size of 3/8 inches.

Ore from the crushed stockpile is then fed to the primary ball mill via conveyor belt, and typically averages 1.0 to 2.0 g/t gold. The ball mill is charged with 2 inch and 3 inch balls, and grinds material to a K80 of 150 micron. Material from the ball mill is pumped through a cyclone, where liberated material is fed into the flotation circuit via an overflow. Any coarse material is returned to the ball mill.
