As Séguéla moves closer to a construction decision, we continue to push towards the goal of defining additional mineralization in support of our vision of Séguéla becoming a 150,000 ounce per year producer over ten plus years,” commented John Dorward, President and Chief Executive Officer of Roxgold. “The assay results today, while still early, build our confidence in the potential for Koula to conceptually extend its life via a high-grade underground operation. The strength of mineralization at depth at Koula is similar to what we were seeing at depth down-plunge in Ancien last year – a program which was temporarily put on hold in order to infill and upgrade the in-pit defined Inferred Mineral Resource at Koula for inclusion into the upcoming Feasibility study. While we had initially viewed Koula as an attractive satellite opportunity it is now clear that it has the potential to be the most important deposit defined at Séguéla so far. In addition, our drills have resumed extension testing at Ancien, the other ultra-high grade deposit discovered to date.

“We continue to believe we have only begun to tap the potential of the Séguéla Project and are eager to continue to uncover and test the wealth of additional targets present on the property. While our exploration team continues their work at Séguéla, the critical path for the Séguéla project plan is on track with the Feasibility Study scheduled for the second quarter of this year, followed soon thereafter by a construction decision towards the goal of achieving first gold pour at Séguéla in 2022.”

Paul Weedon, Vice President Exploration commented “Building off the recent high grade results from the conclusion of the infill program, these new results highlight the potential for an underground target extending down-plunge from Koula and provide a high degree of confidence in the high grades over at least 150 m down-plunge. Coupled with the 14 m at 4.3 g/t intersected in SGRD971 we see mineralization extending at least 250 m at depth and I am looking forward to the results from the next round of step-out drilling, which is testing the potential a further 120 m down-plunge.”

Koula

Located approximately 1 km to the east of Antenna, Koula was discovered through field reconnaissance and coincident recent artisanal workings in an area previously considered to be a lower exploration priority. A diamond drill rig is continuing to test for down plunge extensions to the high grade Koula mineralization, targeting the next 120 m to 150 m step-out further down plunge from the previously deepest intersection of 14 m at 4.3 g/t in SGRD971.

Mineralization is hosted by quartz-carbonate veining associated with a well developed mylonitic fabric within and along the interpreted margins of a tholeiitic basalt, with a very strong structural control evident in the association of a cross-cutting north north-east trending structure. This mylonitic zone can be traced for several kilometres along strike on the regional magnetics and looks to also be associated with the mineralization at Ancien, some 6km to the south.

Quality assurance/quality control

All drilling data completed by Roxgold utilized the following procedures and methodologies. All drilling was carried out under the supervision of Roxgold personnel.

RC drilling used a 5.25 inch face sampling pneumatic hammer with samples collected into 60 litre plastic bags. Samples were kept dry by maintaining enough air pressure to exclude groundwater inflow. If water ingress exceeded the air pressure, RC drilling was stopped, and drilling converted to diamond core tails. Aircore (“AC”) drilling was collected in one metre intervals and sampled in a similar fashion to RC methods. Once collected, RC and AC samples were riffle split through a three-tier splitter to yield a 12.5% representative sample for submission to the analytical laboratory. The residual 87.5% sample were stored at the drill site until assay results were received and validated. Coarse reject samples for all mineralized samples corresponding to significant intervals are retained and stored on-site at the Company controlled core yard.

DD drill holes were drilled with HQ sized diamond drill bits. The core was logged, marked up for sampling using standard lengths of one metre. Samples were then cut into equal halves using a diamond saw. One half of the core was left in the original core box and stored in a secure location at the Company core yard at Séguéla. The other half was sampled, catalogued and placed into sealed bags and securely stored at the site until shipment.

All Séguéla RC, AC and DD core samples were shipped to ALS Laboratories preparation laboratory in Yamoussoukro for preparation. Samples were dried and crushed by the Lab and a 250-gram split prepared from the coarse crushed material, prior to pulverization and preparation of a 200g sample. Samples are then shipped via commercial courier to ALS’s analytical facility in Ouagadougou, Burkina Faso where routine gold analysis using a 50-gram charge and fire assay with an atomic absorption finish was completed. Quality control procedures included the systematic insertion of blanks, duplicates and sample standards into the sample stream. In addition, the Lab inserted its own quality control samples.
