The Wahgnion mine is located in the southwest corner of Burkina Faso within the Paleoproterozoic Birimian Senoufo Belt. The Senoufo Belt trends north-northeast and comprises mainly basaltic and andesitic volcanic rocks, lesser sedimentary rocks, and numerous gabbroic to granitic sub-volcanic plutons.

Mineralization at the Wahgnion Gold project is structurally controlled and is widely associated with hematite, iron carbonate, sericite, pyrite and locally, with albitic alteration. Higher gold grades are commonly associated with stylolitic laminated quartz veins or pyrite veinlets. Coarse- grained gold is found in fractures within pyrite veins or in quartz-carbonate vein selvages. Mineralization is predominantly of a lode-style gold type, associated with discrete structures. The mineralization is interpreted to have formed from the same mineralizing system, with variations in style reflecting the difference in local lithological and structural settings.

Nogbele Deposit
Basement exposure in the Nogbele area is generally poor, with outcrop information limited to occasional exposure in shallow creek beds, shallow mining pits, road cuts, and quartz vein outcrop. Surficial regolith varies from a shallow residual granitic profile to a competent laterite ferricrete ridge that traces the contact of the Nogbele pluton and the host rocks in the Nogbele North area.

The Nogbele area is underlain by a package of metamorphosed and variably deformed volca ........

The Wahgnion mine consists of four main regions; Nogbele, Fourkoura, Stinger, and Samavogo. Gold mineralization occurs in the laterite, saprolite, transition, and primary weathering horizons. Laterite and saprolite are assumed to be free digging material, whereas transition and primary material will be mined via drill and blast cycles.

The Wahgnion mine is a conventional open pit mine, with several pits of varying sizes. The operations consist of five main pit groupings: Nogbele North, Nogbele South, Fourkoura, Stinger, and Samavogo. Gold mineralization occurs in the laterite, saprolite, transition, and primary weathering horizons. Laterite and saprolite are assumed to be free digging material, whereas transition and primary material will be mined via drill and blast cycles.

Mining is by way of conventional open pit mining techniques using drill and blast as required with material movement by hydraulic excavators and trucks. The mine scale suits 90 tonne class excavators in a backhoe configuration matched to 40 tonne payload class mining haul trucks and 40 tonne payload articulated haul trucks. An extensive RC drill program is conducted as part of the grade control strategy. WGO own and operate a significant portion of the mining fleet, which has been supplemented by contractor mining utilizing SFTP and PW for the satellite deposits, working in Nogbele pits as well as Samavogo. Due to the nature of the mineralization, there are multiple small pits which ........
