The deposits at the Séguéla Project are considered orogenic lode style systems. The Antenna, Agouti and Boulder deposits are hosted by brittle-ductile quartz albite vein stockworks, often associated with flow banded rhyolite units or porphyritic intrusives. The Ancien and Koula deposits are hosted by rittle-ductile quartz and quartz carbonate vein networks associated with strongly to intensely sheared tholeiitic basalt.

Antenna Deposit
The Antenna deposit occurs within a greenstone package that comprises (west to east) an ultramafic hangingwall, which isin presumed fault contact with an interlayered package of felsic volcaniclastic rocks and flow banded rhyolitic units, which are then in contact with a mafic (basaltic) footwall unit.

The Antenna gold deposit is a brittle-ductile quartz-albite vein stockwork predominantly contained within the flow banded rhyolite units. The stockwork lode varies in width roughly in proportion with the widths of the rhyolitic units which host it (approximately 3–40 m) and extends over a strike length of approximately 1,350 m. Stockwork veins which host mineralisation show two principal orientations; steep east-dipping and steep west-dipping. Veins in the steep west-dipping orientation range from being ptygmatically folded to undeformed, while veins in the east-dipping direction may be variably boudinaged to undeformed. This evidence suggests syn-deformational emplacement of the vein sets during west over east movement ........

The Séguéla Gold Project will consist of the simultaneous exploitation of the Antenna deposit and the satellite deposits at Koula, Ancien, Agouti, and Boulder. The overallstrategy isto have production from these satellite deposits complement the production from Antenna.

A conventional open pit mining method will be utilized for the Séguéla Gold Project with no free digging assumed for any of the weathering zones. All material will be mined via drilling and blasting activities, followed by conventional truck and shovel operations within the pits for movements of ore and waste material. Mining of benches is proposed using 5.0 m benches done in two 2.5 m flitches.

Mining operations will occur year-round with Roxgold engaging a mining contractor for initial operations, before switching to an owner mining arrangement after 3.5 years. A common pool of equipment will be used and scheduled across all active pits so that movement between the pits is minimized and consumables and spare parts are shared within the fleet.

A total of fourteen mining stages were designed and scheduled for the Séguéla Gold Project, consisting of individual pits or pit stages within a final pit design. Consideration for pit stages was for planning and scheduling practicality purposes. The schedule utilizes the pit and phase designs and stockpiling strategy to fill the mill at 1.25 million tonnes per annum (“Mtpa”) initially and then increasing to 1.57 Mtpa in year 3.
