“The drill program at Séguéla continues to build upon the Feasibility Study through the significant exploration prospectivity demonstrated with the discovery of Gabbro North and the extension drilling results at Sunbird. In addition, the results from deeper drilling at Koula emphasise the underground potential with drill defined high-grade mineralization now extending more than 450m down plunge from the base of the DFS pit shell.” commented John Dorward, President and Chief Executive Officer. “The proposed combination with Fortuna Silver will create one of the best organic growth pipelines among any of the intermediate precious metal producers, supported by peer-leading free cash flow generation, increased scale and diversification, increased liquidity and a lower cost of capital.”

Paul Weedon, Vice President Exploration commented “The scout drilling results from the new Gabbro North prospect continues to emphasise the high-grade potential of Séguéla, building off the recent discoveries of the Ancien, Koula and Sunbird deposits. In addition to the success at Gabbro North, drilling at Sunbird identified several high-grade shoots as we move through the infill and extension drilling program, with the deposit still open to the south and down-dip, while detailed logging has identified a potential faulted offset in the north, meaning this area also remains open along strike.

“Further, the encouraging results from the deep drilling at Koula has successfully intersected 11m at 7.2 g/t from 279m in hole SGDD086 and 11m at 5.5 g/t from 294m in SGRD1204. Structural logging of the depth extension holes identified a gradual rotation in the strike direction of the high-grade shoot, resulting in the actual plunge being slightly shallower than originally projected with some drill holes intersecting the margins of the mineralized envelope. In addition, this program is highlighting the development of a parallel high grade hanging wall lode and I am looking forward to results from further step-out drilling as we consider the potential for our first high grade underground resource at the Séguéla Project.”

Gabbro North

Located approximately 7km north-east from Antenna (Figure 1), Gabbro North was discovered through regional geochemistry soil and surface mapping. Interpreted as hosted by sheared basaltic units within the same regional north-south shear zone which hosts the Agouti deposits approximately 3km to the south, mineralization is coincident with the intersection of several north-east trending structures evident in the regional aeromagnetic dataset. A 12-hole scout RC program on 100m line spacing (Figure 2) was completed over two areas where artisanal mining had recently started, testing two prospects and intersecting silica-biotite altered tholeiitic basalts with quartz+pyrite veining and minor felsic intrusives.

Mineralization remains open along strike and down-dip, with drilling intersecting low-grade or narrow intervals in all the other holes. The high-grade intervals have been interpreted as corresponding to a similar setting as the high-grade shoots at Agouti. Further drilling to test to down plunge/down dip extensions as well as several other untested targets is planned.

Highlights from the initial assays returned from Gabbro North include:

• 8 m at 39.0 g/t Au in drill hole SGRC1152 from 88m including
  • 4m at 76.5 g/t Au from 88m including
  • 1m at 163.0 g/t Au from 89m
• 6m at 5.3 g/t Au in drill hole SGRC1154 from 47m including
  • 1m at 16.7 g/t Au from 51m

Sunbird

Located approximately 1.5km southeast of Antenna, Sunbird is interpreted to be hosted by the same north-south striking mylonitic tholeiite/pillow basalt package that hosts Koula and Ancien. A possible link to the Boulder mineralization is also indicated in the regional aeromagnetic dataset highlighting a south-westerly extension and intersection of the north easterly trending Boulder structure with the tholeiitic unit.

Mineralization is hosted by three sub-parallel quartz-carbonate vein sets associated with well developed mylonitic fabric within and along the interpreted margins of a tholeiitic basalt and consistent with the mineralization styles seen at Koula and Ancien. To the north of Sunbird, detailed logging has identified an interpreted steep north-south striking fault which has offset the northern strike projection.

Mineralization remains open at depth (e.g. SGRC1296: 12m at 4.6g/t) and to the south where SGRC1149 intersected 9m at 11.7g/t from 111m the hangingwall lode (assays pending for the main lode after re-entry and extension drilling), and where SGRC1300, the deepest and southernmost hole, intersected 6m at 8.6g/t from 183m (Figure 3) with the high grade mineralization interpreted as having a moderate southerly plunge, similar to Koula and Ancien. Mineralization also remains open along strike to the north with the interpreted north-south fault potentially offsetting the northern strike projection.

Highlights from the infill drilling program at Sunbird include:

• 12 m at 15.1 g/t Au in drill hole SGRC1290 from 54m including
  • 5m at 33.5 g/t Au from 58m
• 9m at 11.7 g/t Au in drill hole SGRC1149 from 111m including
  • 2m at 16.5 g/t Au from 112m and
  • 1m at 44.6 g/t Au from 116m
• 12m at 4.6 g/t Au in drill hole SGRC1296 from 49m
• 6m at 8.6 g/t Au in drill hole SGRC1300 from 181m including
  • 1m at 33.3 g/t Au from 183m
• 23m at 2.4 g/t Au in drill hole SGRC1270 from 75m
• 23m at 2.0 g/t Au in drill hole SGRC1280 from 25m, followed by a separate interval of
  • 12m at 3.2 g/t Au from 83m
• 6m at 6.8 g/t Au in drill hole SGRC1297 from 18m, followed by a separate interval of
  • 22m at 2.2 g/t Au from 54m
• 6m at 7.0 g/t Au in drill hole SGRC1286 from 123m
• 5m at 3.5 g/t Au in drill hole SGRC1285 from 16m, followed by a separate interval of
  • 9m at 2.2 g/t Au from 90m

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.

Drilling to test the projected depth extensions more than 450 metres down-plunge from the base of the Feasibility Study pit shell has intersected high grade mineralization in the deepest hole to date with SGDD084 returning 3m at 6.1g/t from 533m downhole. Structural logging has also identified a gradual rotation in the strike direction of the high-grade shoot, resulting in the actual plunge being slightly shallower than originally projected with some drill holes intersecting the lower portion of the mineralized envelope, returning lower grade mineralization. Adjusting for the shallower plunge, drilling has successfully intersected 11m at 7.2g/t from 279m (SGDD086) and 11m at 5.5g/t from 294m (SGRD1204).

With high grade mineralization now extended approximately 450m down plunge from the base of the Feasibility pit shell (refer Company press release March 9, 2021), infill drilling and further down-plunge extension drilling will continue in Q3 to determine the potential for an underground mining project at Koula.

• 11m at 5.5 g/t Au in drill hole SGRD1204 from 294m including
  • 1m at 18.6 g/t from 298m and
  • 3m 11.2 g/t Au from 300m
• 3m at 6.1 g/t Au in drill hole SGDD084 from 533m

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.
