ROXGOLD ANNOUNCES NEW HIGH GRADE DISCOVERY AT SEGUELA HITTING 19M AT 26.1 GPT AU AND 12M AT 32.1 GPT AU AT KOULA PROSPECT

Roxgold Inc. has discovered a new high-grade prospect, Koula, at the Seguela gold project located in Ivory Coast.

Highlights from reverse circulation (RC) drilling

Koula:

• 19 metres at 26.1 grams per tonne gold (g/t Au) in drill hole SGRC877 from 189 m including:
  • Two m at 23.0 g/t Au from 192 m;
  • Two m at 52.6 g/t Au from 195 m;
  • One m at 283 g/t Au from 202 m;
• 12 m at 32.1 g/t Au in drill hole SGRC854 from 84 m including:
  • Four m at 92.1 g/t Au from 90 m;
• Eight m at 14.8 g/t Au in drill hole SGRC875 from 45 m including:
  • Two m at 46.2 g/t Au from 45 m and one m at 14.4 g/t Au from 50 m;
• 12 m at 4.7 g/t Au in drill hole SGRC876 from 95 m including:
  • Two m at 20.4 g/t Au from 100 m.

"Rarely do you see results of this tenor in the very first drill holes into a new target," stated John Dorward, president and chief executive officer. "Koula is a recent addition to what is already a considerable portfolio of prospects, yet with these first batch of holes, Koula is demonstrating many similarities to Ancien -- with comparable consistency and style of the high-grade core, alteration style and steep southerly plunging nature.

"Our goal this year at Seguela 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, coupled with today's announcement of a discovery, reinforce the potential for Seguela to achieve this goal. With three rigs currently turning, we are confident that further exploration upside will continue to be realized. Permitting discussions continue to progress well and the feasibility study remains on track for completion early next year."

Paul Weedon, vice-president, exploration, commented: "I am very pleased with the success of the Seguela exploration team in discovering and rapidly advancing this new discovery. Results from an initial 10-hole RC reconnaissance program have been very successful in defining high-grade mineralization extending over a projected strike of more than 300 metres across five drill lines, with the deepest intersection approximately 150 metres below surface. I look forward to the results of the scout RC drilling program, which will progressively work across the high-priority Seguela prospects. This drilling program is following up on the mapping and reconnaissance sampling at Seguela which continues to emphasize the regional prospectivity of the property."

Koula

Located approximately one km to the east of Antenna, Koula was discovered through field reconnaissance and mapping in an area previously considered to be a lower exploration priority.

Results from an initial 10-hole RC reconnaissance program were successful in defining high-grade mineralization over a projected strike of greater than 300 m across five drill lines, with the deepest intersection approximately 150 m below surface. Three diamond core holes will be completed in September, testing further depth extents as well as providing diamond drill core for structural interpretation, and will form part of a program of infill drilling to approximately 50 m centres.

Displaying similar characteristics to those of Ancien in terms of host geology, mineralization style, high-grade tenor and coarse visible gold, Koula remains open to the south with an interpreted southerly plunge remaining to be fully tested. The weathering profile at Koula is very shallow with oxidized material generally less than 15 m below surface.

Highlights from the first 10-hole reconnaissance drilling program at Koula include:

• 19 m at 26.1 g/t Au in drill hole SGRC877 from 189 m including:
  • Two m at 23.0 g/t Au from 192 m;
  • Two m at 52.6 g/t Au from 195 m;
  • One m at 283 g/t Au from 202 m;
• 12 m at 32.1 g/t Au in drill hole SGRC854 from 84 m including:
  • Four m at 92.1 g/t Au from 90 m;
• Eight m at 14.8 g/t Au in drill hole SGRC875 from 45 m including:
  • Two m at 46.2 g/t Au from 45 m and one m at 14.4 g/t Au from 50 m;
• 12 m at 4.7 g/t Au in drill hole SGRC876 from 95 m including:
  • Two m at 20.4 g/t Au from 100 m;
• Two m at 3.3 g/t Au in drill hole SGRC852 from 89 m.

Exploration activities at Seguela have continued to infill and test the extensions of the existing inferred mineral resources at Antenna, Ancien, Agouti and Boulder in support the upcoming feasibility study, while scout RC drilling and auger drilling continue on other high-priority prospects within the project land package.

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-per-cent representative sample for submission to the analytical laboratory. The residual 87.5-per-cent sample was 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 Seguela. The other half was sampled, catalogued and placed into sealed bags and securely stored at the site until shipment.

All Seguela 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 200 g 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.
