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 and plunge shallowly to the northwest and southeast. The associated S3 axial planar cleavage dips gently towards the south and cuts the S2 fabric. D4 deformation produced asymmetric to tight, generally north verging folds with subhorizontal to gently south-dipping axial surfaces. The D4 deformation is marked by broad regional northnortheast-trending anticlines and synclines which affect D1 through D3-relatedstructures and impart a doubly geometry to many of the pre-existing folds. S4 is a roughly northeast-trending fracture cleavage.

Four alteration zones are recognized (Ramezani, 1992). These include; i) a chlorite-calcite zone, ii) an ankerite-sericite zone, iii) a chlorite-magnetite zone, and IV a red albite-pyrite (+gold) zone. The fourth zone of albitization is readily observed in outcrop even from a distance and results in the rocks having a general pink appearance that is readily mapped. Locally leucoxene is observed as part of the alteration assemblage. Quartz veins occur within the mineralized zones both as barren tension gash veins, which are interpreted to postdate the mineralization, and as shear-parallel, quartz– albite–ankerite veins.

The gold within the Stog’er Tight Deposit occurs as fine-grained (<.05 mm) micro veinlets and disseminated blebs within the coarse pyrite aggregates. Visible gold was observed as rare very delicate flakes localized within weathered-out pyrite cubes and in narrow quartz veins. Generally, higher grades are associated with coarse mottled pyrite.

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.

The Pine Cove Mill operates as a grind/flotation circuit followed by leaching. Comminution is via a two-stage crushing plant followed by a 10 feet by 14 feet primary ball mill, which processes an average of 1,350 tpd of ore. Cyclone overflow feeds the flotation circuit, with three column cells for roughing, one scavenger/staged reactor cell, and one cleaner cell. The concentrator has a flotation circuit which produces a gold-pyrite concentrate that advances to the leach circuit. Mass concentration is typically 1.5 to 2.0%, with a recovery of 92 to 93%. Flotation concentrate is thickened in a 4.5 metre diameter thickener and reground in a 5.5 feet by 10 feet diameter ball mill down to a P80 of 20 microns. Leaching is conducted in a series of four 75 m3, mechanically-agitated leach tanks. Two drum filters and a Merrill-Crowe circuit are used for gold recovery from the pregnant solution. Cyanide destruction of leach tailings is achieved through the Inco SO2 process. The mill currently ach ........
