Roxgold Announces New High Grade Discovery at Boussoura, Burkina Faso
TORONTO--(BUSINESS WIRE)--Feb 3, 2020--
Roxgold Inc. (“Roxgold” or the “Company”) (TSX: ROXG) (OTC: ROGFF) is pleased to announce a new high grade discovery at Galgouli, and excellent results following up historic drilling at Fofora at the Boussoura Project in the southern portion of the Hounde Greenstone Belt in southern Burkina Faso (Figure 1). The Hounde Greenstone Belt is host to several operating gold mines, including Roxgold’s Yaramoko Mine which is 190km to the north. The Boussoura Project is located approximately 10 kilometres north of the Côte d’Ivoire border.

Location of the Boussoura Project
“Our exploration team has had tremendous recent exploration success with a new high grade discovery at the Boussoura project following on from the significant increase in total resources at Séguéla announced last week,” stated John Dorward, President and CEO. “We have a very attractive growth pipeline and are well positioned to deliver on our aspirations of being the next West African multi-asset gold producer. We currently have two rigs drilling on the Boussoura project and we are eagerly anticipating further results over the coming months.”
Paul Weedon, Vice President Exploration commented “We are excited about these high grade results, especially from Galgouli as they represent the first drilling into this new discovery and support the numerous high grade rock chip samples collected by the exploration team in late 2019. These results are setting up the potential for Roxgold’s third high grade project. With two rigs currently working on additional infill and extension drilling at Galgouli and Fofora we are looking forward to growing the current mineralized footprint. In addition, we have identified at least 9 other significant vein sets with artisanal workings, each traceable for several hundred metres in length, from which rock chip results highlight the potential for additional high grade mineralization”.

The drill program initially targeted three prospects, following up on field mapping, regional soil and auger geochemical sampling and high grade rock chip results at Galgouli, Fofora and Niolkar (Figure 1). Results from Niolkar, while encouraging, were of a lower tenor relative to Galgouli and Fofora with further work planned to help refine the prospectivity. Mapping and geochemical sampling of several other active artisanal areas will be carried out in the 2020 field season.
Historic reconnaissance work including trenching and RC drilling by Randgold Resources Ltd/Volta Resources Ltd prior to 2012 also highlighted the prospectivity of the Fofora area, with RC results including:
Much of the historic work is associated with an extensive 3km x 3km artisanal field.
22 Reverse Circulation (“RC”) and Diamond Core drill holes (“DD”) at Galgouli has identified high grade mineralization along a >1km trend with drilling to a vertical depth of approximately 250m (Figures 2 and 3). High grade mineralization is associated with a series of steeply dipping quartz-chlorite-carbonate-pyrite veins with coarse gold (1-3mm) commonly identified on vein margins and selvedges. Veining is hosted by variably altered and sheared porphyritic andesites with 5-10m wide alteration zones hosting low grade (<1.5g/t) halos.
Drill highlights include:
Mineralization remains open along strike and at depth, with drilling continuing to infill and extend the strike extent where artisanal workings are indicative of further high grade extensions.

At Fofora, 13 RC and DD holes have intersected high grade mineralization along a 500m zone of artisanal workings (Figures 4 and 5), which remains open at depth and along strike. Mineralization is associated with several quartz-chlorite-carbonate-pyrite veins hosted by sheared and altered porphyritic andesites, commonly with coarse gold (1-3mm) associated with vein margins and selvedges, with broad (up to 40m) alteration zones hosting low grade (<1.5g/t) halos. Drilling is continuing, testing for depth and strike extents to the currently defined mineralization.
Drill highlights include:
Historic reconnaissance RC drilling by Volta Exploration prior to 2012 initially confirmed high grade mineralization at depth, with the recent program designed to validate and extend the limits of the previous work. Fofora is one of several elongate vein sets associated with an extensive 3km x 3km artisanal field which remain untested at depth or along strike, and which will be the focus of ongoing exploration in H1.

Ongoing Drilling Targets New Prospects
Several additional targets have been identified elsewhere at Boussoura permit, and with field mapping ongoing, more are expected to be identified and ranked for prospectivity. Historically, work prior to 2012 focussed around the Fofora area with shallow drilling and trenching, and pre-dated much of the current artisanal workings, with very little work carried out on the remainder of the permit.
Outcrop mapping and the extensive artisanal workings coupled with historic geophysical surveys, has helped develop a good understanding of the key structural controls, assisting with targeting of the host high grade quartz veins. Active artisanal workings in at least 15 localities within the 250km 2 Boussoura permit and which commonly extend for 300-400m, highlight the potential for additional high grade gold mineralization. An extensive auger program is being prepared to test the broad areas that are under surface cover, the results of which are expected to highlight additional targets.
Additional mapping, soil and auger geochemistry and reconnaissance RC/DD drilling will continue during H1.

Paul Weedon, MAIG, Vice-President, Exploration for Roxgold Inc., a Qualified Person within the meaning of National Instrument 43-101, has verified and approved the technical disclosure contained in this news release.

Quality Assurance/Quality Control
All drilling data completed by Roxgold Inc. have utilized the following procedures and methodologies and 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 ground water 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.
Diamond drill holes were drilled with HQ or NQ2 sized diamond drill bits. The core was logged, marked up for sampling using standard lengths of one metre or to geological boundaries as directed by the supervising geologist. 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 RC and diamond core samples were shipped to Actlabs in Ouagadougou 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. Routine gold analysis using a 50-gram charge and fire assay with an atomic absorption finish is then 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.
