Name of the Mine
Sissingué mine.

Location
The Sissingué mine is located in the Savanes region of northern Côte d’Ivoire.

Mine Owner/s
Perseus owns an 86% interest in Sissingué, with a 10% free-carried interest held by the Côte d’Ivoire government and 4% owned by local interests.

Brief Description
The Sissingué operation is an openpit gold mine that includes the main Sissingué pit and smaller satellite pits at Fimbiasso and Bagoé.

Brief History
Perseus acquired the project in 2004 under the name Tengrela. Following exploration success and feasibility studies, an exploitation permit was granted in 2012. Construction of the mine started in 2016 and was completed ahead of schedule and under budget. The mine started commercial production in April 2018 and has since been integrated with the Fimbiasso and Bagoé satellite deposits to extend its life to March 2026.

Primary Metals/Minerals
Gold.

Secondary Metals/Minerals
No secondary minerals are reported.

Geology/Mineralisation
The Sissingué deposit is defined by a 4-km-long and up to 1.5-km-wide gold-in-soil anomaly situated on the Syama-Boundiali greenstone belt. Rocks encountered in outcrops and drilling comprise predominantly north-northeast-striking, steeply west dipping and isoclinally folded metasedimentary rocks (sandstones, mudstones and subordinate conglomerates) of the Birimian Supergroup. The metasedimentary rocks are crosscut by a swarm of narrow quartz-feldspar porphyritic dykes (submetre to several metres thick), which trend obliquely to the sedimentary package north-west with subvertical or steep to moderate dips towards the east. 

The area of the main Sissingué resource also features two irregularly shaped granitic bodies that appear to predate intrusion of the porphyritic dykes. Gold mineralisation at Sissingué is hosted by the porphyritic dykes, granitoid rocks and coarser grained beds (sandstones and conglomerates) in the metasedimentary rocks proximal to the intrusive bodies. Mineralisation occurs as disseminations of pyrite and lesser arsenopyrite in sericite-carbonate alteration zones. Highest gold grades are typically associated with spaced quartz-carbonate veins and increased concentrations of arsenopyrite.

Reserves
As at June 30, 2024, Sissingué and its satellite deposits had combined proven and probable ore reserves of about 4.3-million tonnes grading 1.82 g/t gold.

Resources
Total measured and indicated mineral resources as at June 30, 2024, were reported at 8.7-million tonnes grading 1.57 g/t gold. Inferred resources were reported at 200 000 t grading 1.4 g/t gold.

Type of Mine
Openpit.

Mining Method
Conventional openpit mining using hydraulic excavators and trucks.

Major Infrastructure/Equipment
The mine features a conventional carbon-in-leach processing plant, comprising crushing, semiautogenous milling, gravity concentration, leaching, elution, and gold recovery circuits. 

Other infrastructure includes a 23 km access road, on-site accommodation for 150 nonlocal workers, a diesel-fuelled power plant, tailings storage facilities, a raw water system sourcing from boreholes and the nearby Bagoe river, and an airstrip for regional logistics.

Prospects
Following an assessment of growth opportunities, additional mining inventory has been included from the Sissingué Stage 5 pit. This extends Sissingué’s mine life to the 2030 financial year.
