The Point Rousse Operation contains three deposits Pine Cove, Stog’er Tight, Argyle and the fully permitted Pine Cove Mill.
As announced on October 25, 2022, the Signal has begun winding down its current operations at Point Rousse and has now completed mining at the Argyle Mine. As on March 2, 2023, the Signal continues to wind down its operations at Point Rousse in a safe and profitable manner and has now completed all crushing and grinding activity and is transitioning to care and maintenance. During care and maintenance, the Signal will take the opportunity to review and optimize the Stog’er Tight mine plan.
The Pine Cove Mine serves as a fully permitted tailings storage facility which provides for potential long-term storage of potentially acid generating rock. |

Summary:
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.
Pine Cove Mine
The geological setting of the Pine Cove Mine area is characterized by greenschist facies mafic volcanic and volcaniclastic rocks, clastic sedimentary rocks and minor iron formation; par ........

ARGYLE MINE
The Argyle Mine is an open pit mine consisting of traditional drill and blast operations followed by transport of ore by haul trucks to the crusher run of mine pad and transport of waste to the waste rock piles. On average, between 10,000 and 12,000 tpd of waste and ore is mined.
The primary equipment fleet includes seven John Deere 410E trucks (38 tonnes), two shovels and two bulldozers. Approximately 28 people are employed directly and indirectly in the trucking of ore.
Production holes are typically drilled on a 3 by 3 m pattern with a bench height of 6 m. Explosives used include Titan XL 1000 bulk emulsion for production blasting and Unimax Dynamite for pre-shear blasting. Nonel EZ DET detonators and Trojan Brand Cast boosters are used. There are generally four blasts per week.
Ore is hauled via a single 15 m wide ramp (10% grade) to the ore storage area adjacent to the mill. Oversize material is broken using an excavator-mounted buster. The broken ore is fed into the primary crusher using a dedicated loader. There are several waste rock dumps adjacent to the open pit.
The main access ramps are designed at a 10% gradient to accommodate rear wheel drive haulage trucks. The 18 m wide ramps are designed to facilitate two-way truck traffic a ........
