Highlights from Ancien:
Reverse Circulation (“RC”) and Diamond (“DD”) drilling
“We continue to see the growth potential of the Séguéla Project through the efforts of our exploration team,” stated John Dorward, President and Chief Executive Officer. “The continuing high grade results from infill and extension drilling at Ancien further underpin the excellent Preliminary Economic Assessment results released recently and are expected to add meaningful ounces for inclusion into the Feasibility study early in 2021. With four rigs currently turning, I am confident that we will continue to unearth further upside from the existing four deposits as well as near-term targets on the property which are yet to be tested.”
Paul Weedon, Vice President Exploration commented “The first two results from this 6 hole infill program infilling of the high grade shoot are very encouraging and correlate well to the high levels of visible gold seen in the samples. Designed to confirm geostatistical support for the very high grade and continuous nature of the Ancien mineralized shoot, I am eagerly anticipating the remaining results. Also, the latest extension drilling results continue to highlight the resource upside at Ancien and follow on from the recent excellent results released on April 29th which included 10m at 59.4 g/t from SGRD705 and which is outside of the conceptual shell used for the PEA. These new results have extended the strike extent at depth by an additional 50m to the south where it remains open, while the 7m at 28.8 g/t in SGRD725 emphasises the emerging high grade potential of the hangingwall shoot, which also remains open along strike.”
Exploration activities have continued to progress to extend and infill the existing Inferred Mineral Resources within proximity to Antenna to support the Feasibility Study. Agouti, Boulder and Ancien, are within 10 kilometres of the Antenna deposit (Figure 1).

An additional 69 RC/DD holes have been completed at Ancien since the drill hole data cut-off date (February 12th, 2020) used to support the Inferred Resource estimate in the PEA of 261,000 ounces (refer Company release April 14th, 2020). Further to the results from 59 holes reported in April (refer Company releases dated April 20th and April 29th, 2020), we have received results from 8 drill holes completed since the resumption of field activities in late May.
These most recent results (illustrated in Figure 2) reflect the two objectives of the current programs, namely a dedicated infill program for geostatistical support of the very high grade and continuous nature of the core Ancien mineralization, and targeting depth and strike extensions to the high-grade core beyond the PEA US$1,550/oz conceptual pit shell.
The results from the first two of six holes of the high grade infill program highlight the broad nature of high grade intervals, both along strike as well as across the mineralized zone, and correlate well with the high levels of visible gold logged in the samples. The remaining four drilled intervals also recorded similar levels of visible gold during logging and these results will be available in the coming weeks.
Drill testing of the down-plunge extension continues to expand the shoot to the south with results such as 14m at 4.3 g/t from SGRD723 and 14m at 2.6 g/t from SGRD720, expanding the strike length to at least 250m where it remains open beyond 350m below surface. Lower grade results from SGRD724 (3m at 1.0 g/t Au) supports an interpretation of a gradual flattening in the plunge of the main zone of mineralization.
Extension drilling testing the down plunge projections of the emerging high grade hangingwall lode was also successful with SGRD725 intersecting 7m at 28.8 g/t, approximately 75m below the conceptual pit base and further confirming the high grade nature of this second high grade lode, and follow on from the recent SGRD715 (3m at 26.1 g/t) and SGRD541 (4m at 17.4 g/t) results (refer Company release April 29th) and which also remains open at depth and along strike to the north.

Figure 2 also highlights the extent of additional high grade mineralization beyond what was used to support the PEA, in particular the down-plunge extensions beyond the conceptual pit shell. The resource infill program within the conceptual shell has also extended mineralization along strike to the south and highlighted the potential for further resource growth.

Good progress has been made with all geotechnical drilling completed for Ancien, Antenna, Agouti and Boulder for inclusion into the open pit design component of the feasibility study. Samples are in the process of being forwarded to Perth, Western Australia for rock property analysis. Initial field logging supports the assumptions used for the PEA inputs into the US$1550 conceptual pit shells.

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 Séguéla. The other half was sampled, catalogued and placed into sealed bags and securely stored at the site until shipment.
All Séguéla 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 200g 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.
