"The infill program for Koula to bring the deposit into the upcoming Séguéla Feasibility Study has been successfully completed," commented John Dorward, President and Chief Executive Officer of Roxgold. "Since announcing the discovery of Koula six months ago, we have seen the deposit repeatedly return some of the highest grade intersections drilled to date on the property, reinforcing the December 2020 Séguéla resource update which included a maiden inferred mineral resource from Koula of 281,000 ounces at 8.1 g/t - making Koula among the highest grade open pit gold deposits in West Africa. The implications of the inclusion of Koula into the Feasibility Study are apparent, and we are confident that the market will see material improvements upon the already robust Preliminary Economic Assessment when the Feasibility Study is released next quarter.

"While the infill program for Koula has been completed, our drills are still turning, as we look to test the extension potential of Koula along strike and at depth; as well as returning to Ancien to resume the extension testing program which was deferred upon the discovery of Koula. Additionally, our scout drill program has resumed as we have over 28 named targets across the Séguéla project and continue to identify further targets with boots on the ground. Séguéla has already become a cornerstone asset for Roxgold, and we believe that the project will continue to grow in importance in our portfolio as we advance it toward initial production next year and expand its scope through additional exploration success."

Paul Weedon, Vice President Exploration commented "These outstanding high grade results mark the conclusion of the Indicated infill drill program ahead of modelling and inclusion in the forthcoming Feasibility Study due in the second quarter. These results continue the high grade theme that we have seen at Koula, with results such as 12m at 38.3 g/t from 180 metres down-hole in SGRD1065, 16m at 28.3 g/t Au in drill hole SGRD1083 from 77m down-hole, and 15m at 24.0 g/t Au in drill hole SGRC1025 from 42m down-hole. With the deposit open down-plunge, drilling has started on deep step-out holes approximately 120m further down-plunge from the previously deepest intersection of 14m at 4.3g/t intersected in SGRD971."

Koula

Located approximately 1km 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 4 rig infill program of RC and diamond drilling with the goal of infilling the deposit to 25m centres to support an upgraded Indicated classification has been completed. This further supports the rapid advancement and inclusion in the forthcoming Feasibility Study.

Mineralization is hosted by quartz-carbonate veining associated with a well developed mylonitic fabric within and along the interpreted margins of a tholeiitic basalt which in turn has been tightly folded. Coarse gold is commonly recorded in the higher grade zones (eg. Figure 3 - coarse gold in drill core, SGRC1083), with drilling highlighting a consistent moderate southerly plunge to the high grade core over at least 350m, and where it remains open to the south with hole SGRD971 intersecting 14m at 4.3 g/t Au from 273m downhole.

Catalysts and Next Steps

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.
