ROXGOLD REPORTS SOLID 2019 FIRST QUARTER PRODUCTION RESULTS AND PROVIDES EXPLORATION UPDATE AT YARAMOKO
Roxgold Inc. has released its 2019 first-quarter (Q1) production results and provided an exploration update from the company's Yaramoko gold mine located in Burkina Faso.
Achieved solid production results with 33,652 ounces of gold produced in Q1
- Realized record quarterly throughput of 106,816 tonnes which exceeded increased nameplate capacity of 1,100 tonnes per day by approximately 8%
- Accelerated regional exploration activities with the conclusion of the 55 Zone deep drilling program, including core drilling on Bagassi South extensions, Reverse Circulation ("RC") testing of soil geochemistry anomalies, and extending the auger drilling across new prospects
- Commenced RC drilling at the Seguela gold project's Antenna deposit on April 24th, and aircore drilling commenced at Kwenko West on April 29th
"The first quarter saw a solid operating performance at Yaramoko with gold production of 33,652 ounces and with production weighted towards the second half of the year, we remain on track to achieve our annual production guidance of between 145,000 and 155,000 ounces. The recently expanded process plant continued to outperform achieving record throughput and operating approximately 8% above nameplate capacity during the quarter. The development ramp-up at Bagassi South has progressed well and we are on track to commence stoping operations during the second quarter as scheduled," stated John Dorward, President and CEO of Roxgold. "Regional exploration is currently underway with four rigs testing several structural and geochemical anomalies across the license, while an extensive auger program continues to generate new anomalies."
At the 55 Zone, 85,460 tonnes of ore were mined at 10.6 grams per tonne ("g/t Au") and 1,272 metres ("m") of development were completed. During the quarter, approximately 80% of ore mined came from stoping activities as a result of extensive development in place at the 55 Zone with three open stopes available at the end of the quarter. During the quarter, decline development reached the 4879 level, approximately 440m below surface. At Bagassi South, ramp-up activities continued to progress well during the quarter with 992m of development completed. Yaramoko is expected to produce stronger quarters in Q3 and Q4 due to the Bagassi South mine commencing stoping operations during Q2 2019.
The plant processed a record throughput of 106,816 tonnes at an average head grade of 10.0 g/t Au for the quarter. Plant availability was 95.4% and overall recovery remained high at 98.3% during the quarter. The unit throughput rate at the plant has consistently increased since the completion of the process plant expansion work resulting in throughput rates exceeding nameplate capacity by approximately 8%. The lower average head grade was primarily due to the ramp-up of the Bagassi South underground mine which is currently delivering development ore.

13 holes were completed at the 55 Zone during the quarter, completing the surface infill and depth extension program which commenced in April 2018. The program completed 46,444m with the objectives of upgrading inferred to indicated at depth, improving definition of the high-grade shoots within the wider ore envelope, and refining the inferred mineralization at depth.
While returned grades were low in drill holes YRM-19-DD-493 and 493W1, difficulties in maintaining hole direction resulted in both holes ending approximately 20-25m to the west of their target, the down plunge extension of the high grade shoot intersected in YRM-17-DD-443W1 (12.5m at 11.2g/t Au and 3.9m at 12.9g/t Au).
All results from the program have been received with wireframing underway in preparation for the forthcoming updated Mineral Resource Estimate which is due for release in Q2 2019.
Table 1 presents the drilling results from Q1 2019 and includes the following significant results:
YRM-19-DD-493W1: 2.7m at 0.7g/t from 1,368m downhole
YRM-19-DD-426W1: 0.6m at 30.8g/t Au from 1,063.4m downhole
YRM-19-DD-439W1: 3.4m at 9.4g/t Au from 999.2m downhole
YRM-19-DD-488W1: 5.2m at 2.5g/t Au from 1,183.4m
Drilling activity also continued at Bagassi South with six holes (2,529m) completed during the quarter. At QV1, four holes (1,504m) were designed to test interpreted contact zones 100m -- 200m down plunge from the Western Shoot on the eastern side of a large cross-cutting dyke. While assays are pending, logging highlights the continuation of the QV1 structure as defined by a 10m-20m wide sheared zone with up to six metres of quartz veining and moderate sulphide development present.
At QV Prime, two holes were completed (1,025m), targeting the continuity of the QV Prime structure and its association with the granite-mafic volcanic contact approximately 200m down plunge. Geological logging indicates the contact may have shallowed slightly with the remaining four holes being redesigned as a result. The assay results are pending.
RC and core drilling were carried out at several prospects (Figure 1) following up earlier geochemistry and structural anomalies with a total of 3,752m drilled during the quarter. Key work programs included:
- Kaho -- testing previous RC anomalies along coincident structural and geochemical corridors intersected several moderate to strongly sheared zones with sericite alteration, quartz veining and pyrite. The best results were from YRM-19-DDKOA-018 with 2m at 1.6 g/t Au. Importantly the presence of shearing, quartz veining and alteration supports the regional structural interpretation associated with the Yaramoko and Bagassi South mineralization.
- Haho -- Three core holes (383m) were completed with one hole confirming the down dip extension of mineralization previously intersected during the 2017/18 field season, intersecting shearing with associated quartz veining, alteration and minor pyrite.
- Zone 109 -- Three core holes (449m) were completed following up a shear zone previously intersected in YRM-13-K109-003 (2013 program), with each hole intersecting a well-developed shear zone (up to 12m width) with associated chlorite and carbonate alteration, quartz veining and minor pyrite.
- Tarkwaian West Contact -- 7,990m of RC drilling on 200m spaced lines have been completed at the Tarkwaian West Contact zone, testing extensive array (+6km) of soil geochemistry anomalies along the western interpreted contact between a Tarkwaian inlier and volcaniclastic sediments/mafic volcanics. This contact is also interpreted as a splay from the regional Boni Shear. RC drilling has also identified a set of regional north-east trending shear zones which coincide with several of the geochemical anomalies, with shearing typically associated with broad alteration zones, quartz veining and minor pyrite. Several zones of low-grade mineralization were intersected, typically in the range of 2m-4m at 0.1-0.3g/t Au. A full interpretation will be carried out once all results have been received next quarter.
- SAN -- 3,741 meters of RC drilling was completed, testing coincident soil geochemistry anomalies and structural contacts between Birimian sediments and a granodioritic intrusive, with encouraging visual results from YRM-19-RC-SAN-30 to-34. Drilling was continuing at the end of the quarter and assays are pending.
Auger drilling continued at Kaho and started at the 300 Zone, with a total of 10,650m drilled during the quarter.
- Q2 -- Commercial production expected to be achieved at Bagassi South
Q2 -- Updated Reserves and Resource Statement released
Q3 -- Initial exploration results from recently commenced Seguela exploration program
