Roxgold Reports 26.9 GPT Over 4.8 Metres at Boussoura as Drill Program Continues to Expand Additional Fofora Vein Sets
TORONTO--(BUSINESS WIRE) -- September 14, 2020 -- Roxgold Inc. (“Roxgold” or the “Company”) (TSX: ROXG) (OTCQX: ROGFF) is pleased to announce new exploration drilling results from the Company’s Boussoura Project, located in southern Burkina Faso.

“The exploration success at the Boussoura Project continues to build our confidence in the potential for the project to become Roxgold’s third high value asset,” stated John Dorward, President and CEO. “We announced the discovery of Boussoura in February of this year and have drilled over 70 holes with consistent assay returns demonstrating broad intersections of mineralization with lower grade halos surrounding higher grade quartz veining at Fofora and high grade veins at Galgouli. We are excited by the potential scale of this project with multiple additional veins with active artisanal workings yet to be tested and numerous targets identified on our exploration permit with similar geochemistry and geophysical anomalies. Going forward, the focus will be on drilling the additional 5 vein sets identified at Fofora, testing targets near Galgouli and conducting an aircore drill program to prioritise the regional targets that have demonstrated high prospectivity from recent geochemical results.”
Paul Weedon, Vice President Exploration commented “We have now identified over 9 mineralized vein sets over 4 vein corridors across only a third of the 9 km2 active area at Fofora. The results today further highlight the potential we see at Boussoura, with high grade results such as 4.8m at 26.9g/t Au from BSR-20-RD-FFR-040 and 9m at 10.7g/t Au from BSR-20-RC-FFR-063 underpinning the high grade nature of the veining we see there.
“In addition, these results include a re-entry and extension of hole BSR-19-DD-FFR-011 drilled at the main Fofora vein last year, which returned 6.7m at 6.4g/t Au, including 0.4m at 94g/t Au from 249.6m, emphasising the depth continuity of the veins and is one of the deepest intersections to date.”
Boussoura Project – Burkina Faso
The Boussoura Project is situated in the southern portion of the Houndé Greenstone Belt which is host to several large-scale operating gold mines, including Roxgold’s Yaramoko Mine which is 190km to the north as well as Endeavour Mining’s Houndé and Mana gold mines. The Boussoura Project is located approximately 10 kilometres north of the Côte d’Ivoire border (Figure 1).
Figure 1. Boussoura Project Location on Houndé Belt
The Boussoura tenement covers an area of over 250 square kilometres (“km2”) with an earn-in agreement in place over an additional 250 km2 of neighbouring permits. The primary targeted areas of the Boussoura Project are Fofora, in the north, and Galgouli, in the south. Fofora has seen a minor amount of exploration in the past, while Galgouli was a new discovery by Roxgold (refer to Company news release dated Feb 3, 2020).

At least 9 sets of shear zones and vein corridors have been identified to date within an active 9 square kilometre artisanal field in the Fofora area of the Boussoura Project (Figure 2). Drilling resumed at Fofora in early May, testing 5 new vein corridors within 2 kilometres to the west of the main Fofora Vein. Each of the 5 vein corridors were considered high priority targets, each having coincident artisanal workings, and geophysical and geochemical anomalies and consisting of a series of north to north-west striking shear zones with surface strike lengths of up to 1,000m. These targets form part of the broader Fofora artisanal field and are very similar in appearance to the high grade Fofora main vein (Figure 3).
Mineralization is typically associated with a series of sheared felsic dykes, associated quartz veining and intense silica alteration and replacement, with a variable dip from steep westerly to ~70 degrees east with coarse gold commonly seen in samples. Two mineralization styles have now been recognized at Fofora, with very broad lower grade zones (typically 0.5-1.0g/t) extending up to 60m in width and interpreted as representing broad siliceous halos to much higher grade quartz veins (10 to >100g/t intervals with high levels of coarse gold) over 1-4m intervals.
There were 12 additional RC and RC with diamond tail holes completed at the Fofora Main vein, with a line of 5 holes successfully extending the strike an additional 150m to the south. Results included 9m at 10.7 g/t from BSR-20-RC-FFR-063 from 71m, and the vein remains open along strike.
In addition, 5 holes successfully intersected an interpreted parallel subsidiary vein on the eastern margin of Fofora Main with results including 14m at 3.0 g/t in BSR-20-RC-FFR-070 from 2m, and 22m at 2.1 g/t from BSR-20-RC-FFR-062 from 40m. A re-entry and extension of drill hole BSR-19-DD-FFR-011, targeting interpreted depth extensions, returned 6.7m at 6.4 g/t from 244.3m while drill hole BSR-20-RD-FFR-040 intersected several well mineralized intervals, the highlight of which was 4.8m at 26.9 g/t Au from 79.5m, including a 0.8m interval of 147 g/t Au. These depth extensions and parallel structures remain open along strike and at depth.

Reconnaissance RC drilling tested vein targets up to 2 kilometres to the west of the main Fofora vein, with recent results including 12m at 5.7 g/t from 74m in BSR-20-RC-FFR-052, 30m at 1.3 g/t Au from 0m in BSR-20-RC-FFR-053A which included 2m at 10.0 g/t Au from 14m and a separate interval of 2m at 11.4 g/t Au from 76m, and 17m at 2.1 g/t Au from BSR-20-RC-FFR-079 from 41m with these results increasing the extent of mineralization highlighted in the previous company release (refer to Company news release dated July 29, 2020).
Reconnaissance drilling is continuing to test targets a further 1 kilometre west and south with further work to test the balance of the 3km by 3km artisanal field planned for Q4 this year, after the conclusion of the current rainy season.

All results are reported as down-hole intervals which represent approximately 70% of true width, except for FFR-047 which was drilled oblique to the interpreted dip of the mineralization, with true width assumed to be ~40% of reported downhole width.

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 Yaramoko. The other half was sampled, catalogued and placed into sealed bags and securely stored at the site until shipment.
All Boussoura RC, AC and DD core 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.
