SnapshotThe Pine Cove deposit is a part of the Point Rousse Operation.

Mining at the Pine Cove Mine concluded in October of 2020. The 2021 Pine Cove Stockpile Mineral Resource was depleted in 2022.

Exploration is being conducted of the mineral potential at the former Pine Cove open pit mine following the Maritime’s recent identification of a thick zone of mineralization extending over 200m below the pit bottom.

In 2024, the Maritime will continue to manage the Pine Cove processing facility on a care and maintenance program.

Technical evaluations will be completed to assess any required modifications to the process plant to accept feed from the Hammerdown project.

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.

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; part of the Snooks Arm Group. In the immediate mine area the rocks can be informally divided into five distinct units that dip gently to the north.

Mineralization is associated with a broad alteration envelope characterized by broad zones of very finegrained calcite and chlorite. Proximal to mineralization fine wispy orange-brown leucoxene is common in intrusive rocks and is either chaotically oriented or rotated and flattened parallel to the foliation. Where alteration is most intense, and gold mineralization occurs, iron-carbonate is pervasive, variably developed, brecciated, quartz-veins and quartz-carbonate veins are observed as well as albite. Pyrite is part of the alteration assemblage and intimately associated with gold mineralization.

Pyrite occurs marginal to the quartz veins, disseminated within wall rock fragments incorporated in the veins, and as minor disseminated pyrite within the quartz veins. The gold concentrations are directly related to pyrite content. The gold occurs as small disseminated grains (ranging from 1 to 50 microns) within pyrite, quartz veins and as thin stringers.
