“With this second round of drilling results, the Koula prospect is rapidly demonstrating its potential to add material value to the Séguéla Gold Project,” stated John Dorward, President and Chief Executive Officer. “Koula was a recent addition to what is already a considerable portfolio of prospects and is continuing to demonstrate many similarities to the high-grade Ancien deposit with comparable consistency and style of the high grade core, alteration style and southerly plunging nature. With a fourth rig due to join the program in the coming days, we are looking forward to seeing this high grade prospect emerge as high value deposit – joining Antenna, Ancien, Agouti and Boulder in the forthcoming Feasibility Study.

“Our goal this year at Séguéla has been to build upon the PEA and demonstrate the potential for the project to grow in quality, scale and scope. We believe that this year’s stream of exploration results, reinforced again with today’s results from Koula, build confidence in the potential for Séguéla to ultimately achieve this goal and that further exploration upside will continue to be realized as we progressively work across the high priority Séguéla prospects. Permitting discussions continue to progress well, as evidenced by the recently approved Environmental and Social Impact Assessment (“ESIA”) and our Feasibility Study remains on track for completion in the first half of next year.”

Paul Weedon, Vice President Exploration, commented, “The follow-up results from Koula underscore what is shaping up to be another high grade addition to the Séguéla portfolio, with outstanding results such as 4m at 108.9 g/t from 32 metres down-hole in SGRC919, 9m at 30.1 g/t from 205 metres down-hole in SGRC935 and 9m at 49.3 g/t Au from 73 metres in SGDD072. Mineralization remains open along strike to the south and extends at least 350m down plunge, with the deepest mineralized intersection of 9m at 30.1 g/t Au approximately 175m below surface indicating that mineralization remains strong.”

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.

An infill program of RC and diamond drilling to 50m centres has started, following up from the initial and very successful, 10 hole reconnaissance RC drill program. With three drill rigs operating at Koula and a fourth to join shortly, infill drilling to 50m centres will support the rapid advancement to an initial Inferred resource for Koula with the potential to include the prospect in the upcoming 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, 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.

Figure 2. Koula assay results and assay status

Three shallow RC holes (SGRC913, 915 and 917) which returned relatively lower grades have been interpreted as intersecting the remnant halos of near-surface high grade mineralization associated with shallow (<10m vertical) artisanal mining activity.

Re-logging of the initial 10 hole discovery program indicated the discovery hole, SGRC854 (12m at 32.1 g/t Au), stopped short in an unmineralized dyke, and has subsequently been extended to 189m, with visible mineralization and alteration resuming approximately 1m further on from the previous barren end of hole, and extending a further 20m. Assays for this interval are pending. A second hole on the same section (SGRD855 – initially NSI) will also be extended to test for potential extensions (Figure 3).

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.
