Roxgold Announces Updated Drilling Results From the Séguéla Gold Project

Roxgold Inc.  is pleased to announce drilling results from the Company’s Séguéla gold project (“Séguéla”) located in Côte d’Ivoire.

Highlights:

Reconnaissance Reverse Circulation (“RC”) drilling at Agouti:

  • 9 metres (“m”) at 2.5 grams of gold per tonne (“g/t Au”) in SGRC231 from 33m; and
  • 5m at 10.2 g/t Au in SGRC232 from 43m.

Reconnaissance RC drilling at P3:

  • 9m at 2.6 g/t Au in SGRC238 from 42m.

Aircore drilling between Boulder and Agouti:

  • 8m at 1.5 g/t Au from 8m in SGAC6508 (ended in mineralization); and
  • 7m at 2.5 g/t Au from 8m in SGAC6511 (ended in mineralization).

“The recent release of the maiden NI 43-101 Mineral Resource Estimate for the Antenna deposit has highlighted the robust nature of the deposit and its potential amenability for open pit mining, while the preliminary results from Agouti demonstrate the potential for satellite pits along the main structures. Agouti is one of several prospects that will be drilled in the coming months, positioning the Company for further strong development,” stated John Dorward, President and Chief Executive Officer.

“Work since the completion of the maiden Mineral Resource Estimate for the Antenna deposit has moved to further drilling with the objective of growing the mineral resource inventory through aircore and reconnaissance RC drilling, while advancing the promising Boulder and Agouti prospects,” commented Paul Weedon, Vice President, Exploration. “Very encouraging drill results from infill and extensional drilling at Boulder and Agouti are providing a solid foundation as we work towards delivering a maiden Mineral Resource estimate for both prospects by the end of the year. In addition, the area between Boulder and Agouti is emerging as a promising new area of focus. While exploration activities at Séguéla remain a priority, we will also be conducting an airborne geophysical survey over several of the highly prospective regional permits. The results will assist in refining the extensive stream sediment and termite mound anomalies generated during previous early stage reconnaissance work.”

Côte d’Ivoire

Séguéla

Exploration activities have moved to working towards delineating additional mineral resources within close proximity to Antenna. Located along north-south trending large scale regional structures, these targets have the potential to increase the mineral resource base of the Séguéla project.

Boulder

The recent drilling at Boulder has highlighted the key controlling structures across at least three separate lodes extending over approximately 750m of strike length. Additional infill and extensional drilling along strike (3,300m planned) is underway. Results from this drilling are planned to be incorporated into a maiden Mineral Resource estimate for Boulder in Q4.

Modelling has also highlighted the linkage to Agouti, approximately 1.2 kilometres north, which has been confirmed through 200m spaced fences of aircore drilling. Several attractive targets along this corridor will also be tested in Q4.

Agouti

Five scout RC holes (513m) were completed at Agouti with all holes successfully confirming the previous broad spaced RC drilling conducted by Newcrest West Africa Holdings Pty Ltd (“Newcrest”) over a mineralized strike length of greater than 600m. Planning and preparation for infill drilling is well advanced and scheduled to commence immediately after completion of the Boulder infill drilling in mid-September.

Highlights from the recent RC drilling include:

  • 6m at 1.3 g/t Au from 23m and 9m at 1.2 g/t Au from 39m from SGRC228;
  • 9m at 2.5 g/t Au in SGRC231 from 33m; and
  • 5m at 10.2 g/t Au in SGRC232 from 43m.

Wide-spaced aircore drilling along the 1.2 kilometre structure linking Agouti to Boulder has been successful in delineating several zones of mineralization coincident with quartz veining, alteration and rhyolite with results including:

  • 9m at 1.0 g/t Au from 10m in SGAC6456;
  • 5m at 4.0 g/t Au from 9m SGAC6465 (ended in mineralization);
  • 9m at 1.8 g/t Au from 1m in SGAC6467;
  • 7m at 1.0 g/t Au from 0m in SGAC6468;
  • 8m at 1.5 g/t Au from 8m in SGAC6508 (ended in mineralization);
  • 7m at 2.5 g/t Au from 8m in SGAC6511 (ended in mineralization);
  • 10m at 0.9 g/t Au from 0m in SGAC6542;
  • 2m at 10.0 g/t Au from 7m in SGAC6543; and
  • 5m at 1.3 g/t Au from 5m in SGAC6546.

P3

Infill Aircore drilling over approximately 700m of strike was completed at the P3 prospect testing historic Newcrest geochemistry and wide-spaced aircore drill results, successfully extending the historic anomalies. In addition, five reconnaissance RC holes were also completed, with results including:

  • 9m at 2.6 g/t Au in SGRC238 from 42m;
  • 7m at 2.2 g/t Au in SGRC239 from 77m; and
  • 2m at 5.5 g/t Au in SGRC240 from 60m.

Kwenko West

Aircore drilling at the Kwenko West prospect has been completed and generated several anomalies with preparations underway for follow-up reconnaissance RC drilling. This program was designed to test a series of soil anomalies along a 2.5 kilometre zone associated with granite-mafic contact, including areas of historic artisanal workings, where zones of fine pyritic quartz stockwork veins have been identified.

Regional

An airborne geophysics program is expected to occur in September 2019. The program is designed to improve the understanding of the key controlling structures and geology on five of the permits, (including Séguéla) and to assist with refining target generation. Previous early-stage reconnaissance work by Newcrest highlighted several broad stream sediment and termite mound anomalies extending over several kilometres at Dianra (14km) and Bouake (9.5km), and the program has been extended to cover the recently granted Kadyoha permits.

Quality Assurance/Quality Control

Séguéla

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 ground water 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.

Diamond drill holes were drilled with NQ2 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 RC, AC and diamond core samples were shipped to ALS Laboratories preparation laboratory in Yamassoukro 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 Kumasi, Ghana 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.
