TORONTO,--(BUSINESS WIRE)-- Roxgold Inc. (“Roxgold” or the “Company”) (TSX: ROXG) (OTCQX: ROGFF) is pleased to announce near-surface infill drilling results from the 55 Zone at the Yaramoko Mine Complex, drilled as part of a review of opportunities for near-surface mineralization to complement our high-grade underground operations.

“Earlier this year we initiated a review of near-surface mineralization opportunities across the Yaramoko property to complement our high-grade underground operations. This review identified the near-surface portions of 55 Zone that extend outside of the existing underground Mineral Resource as a priority target,” stated John Dorward, President and CEO. “Drilling results which included 6m at 77g/t Au from 38m in YRM-19-RC-55Z-003 highlight the substantial opportunity that remains in the near-surface environment to extend the mine life at Yaramoko. These results will be incorporated into an interim Mineral Resource and Reserve update to be released in the fourth quarter of 2020.

“Extending the mine life at Yaramoko has long been a priority for us and between the success of this shallow drilling program, together with our recently commenced underground drilling program from 600 metres below surface, I am confident that we will build a compelling body of evidence over the coming quarters to showcase the long-life nature of Yaramoko. The 14,500m underground program is designed to upgrade resources at depth and the results will be incorporated into the annual Mineral Resource and Reserves update to be released in the first half of 2021.”

55 Zone – Review of near-surface mineralization opportunities

An RC drilling campaign to test the extent of mineralization in the near-surface portion of the 55 Zone has been completed, successfully intersecting several high grade intervals close to surface and above zones previously mined from underground in the early stages of the 55 Zone mining operation. These zones are located beyond the current Mineral Resource envelope and represent the potential for additional Mineral Resources to be defined.

The focus of this drill program was to target potential open pit opportunities proximal to the 55 Zone and represented the first stage of a renewed Yaramoko Mine Complex regional exploration program. The objective of the first stage is to determine the potential for an open pit operation to complement the high-grade underground operation and extend the mine life at the 55 Zone. Several other early stage opportunities have been identified across the Yaramoko property (refer to Figure 2) as part of a regional targeting exercise that will be followed up over the next 12 months to assess further near-surface mineralization opportunities across the Yaramoko property.

Highlights from the RC drilling at 55 Zone include:
• 6 metres (“m”) at 77.2 grams per tonne gold (“g/t Au”) in drill hole YRM-19-RC-55Z-003 from 38m including ? 1.0m at 107 g/t Au from 39m and
? 1.0m at 220 g/t Au from 42m

• 6m at 49.5 g/t Au in drill hole YRM-19-RC-55Z-005 from 41m
• 5m at 7.2 g/t Au in drill hole YRM-19-RC-55Z-006 from 40m including ? 1.0m at 30.2 g/t Au from 41m

• 11m at 10.1 g/t Au in drill hole YRM-19-RC-55Z-012 from 14m
• 4m at 16.2 g/t Au in drill hole YRM-19-RC-55Z-017 from 40m
• 4m at 7.5 g/t Au in drill hole YRM-19-RC-55Z-018 from 30m
• 2m at 29.5 g/t Au in drill hole YRM-19-RC-55Z-019 from 41m including ? 1m at 56.1 g/t Au from 41m

• 3m at 11.3 g/t Au from 35m in drill hole YRM-19-RC-55Z-004
• 7m at 3.6 g/t Au from 15m in drill hole YRM-19-RC-55Z-020
• 7m at 6.6 g/t Au from 36m in drill hole YRM-19-RC-55Z-032
• 7m at 5.0 g/t Au from 40m in drill hole YRM-19-RC-55Z-034
• 6m at 23.8 g/t Au from 13m in drill hole YRM-19-RC-55Z-052

The results of this drilling program, in addition to the historical drill results and remnant halo mineralization, will be incorporated into an updated Mineral Resource and Reserve estimate to be released in the fourth quarter of this year. Alongside the surface program, Roxgold has recently initiated a 14,500m underground drill program aimed at primarily converting underground Inferred Resources to Indicated Resources in support of its Annual Mineral Resource and Reserve Estimate update to be released in the first half of next year.

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. Once collected, RC 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.

All 55 Zone RC samples were shipped to ALS Laboratories laboratory in Ouagadougou for preparation. Samples were dried and crushed by the laboratory and a 250-gram split prepared from the coarse crushed material, prior to pulverization and preparation of a 200g sample with routine gold analysis using a 50-gram charge and fire assay with an atomic absorption finish. Quality control procedures included the systematic insertion of blanks, duplicates and sample standards into the sample stream. In addition, the laboratory inserted its own quality control samples.
