Orezone Grade Control Program in A1 Starter Pit Returns Consistent High-Grade Intercepts Including 20.00 Meters of 4.49 g/t Gold and 11.00 Meters of 7.48 g/t Gold
VANCOUVER, April 07, 2022 - Orezone Gold Corp. (TSX: ORE, OTCQX: ORZCF) (the "Company" or "Orezone") is pleased to report initial assay results from the maiden grade control (GC) reverse circulation (RC) drill program on its A1 deposit at the Bombor? Gold Project, located in Burkina Faso. GC holes drilled to-date have targeted early mining areas from near-surface oxide mineralization within the A1 starter pit. The GC drilling has both confirmed the reserve model and returned several significant
high-grade intervals where localized areas of thick, higher grades have now been confirmed.
Drilling Highlights
- 20.00 m of 4.49 g/t Au from 27.00 m
- 11.00 m of 7.48 g/t Au from 6.00 m
- 19.00 m of 3.62 g/t Au from 1.00 m
- 23.00 m of 2.88 g/t Au from 19.00 m
- 24.00 m of 2.21 g/t Au from 1.00 m
- 10.00 m of 3.84 g/t Au from 18.00 m
- 6.00 m of 6.19 g/t Au from 44.00 m
- 9.00 m of 4.07 g/t Au from 35.00 m
- 6.00 m of 5.62 g/t Au from 25.00 m
- 5.00 m of 6.27 g/t Au from 32.00 m
The closely spaced GC drilling confirms the geological interpretation and grade estimation in the A1 starter pit. GC drilling is progressing as planned in accordance with the pre-production mining schedule across the multiple starter pit areas.
Patrick Downey, President and CEO stated, "We are very pleased with the initial GC drilling results at the A1 starter pit which has not only confirmed but extended the high-grade geological and reserve models. The high-grade zones are up to 40 m thick with average widths of 15-20 m with ore starting right at surface. The GC program is now continuing at the A2 and H1 pits, which are also high-grade starter pits, and mining from these pits will provide the first 12 to 15 months of ore feed to the plant. We remain on-time and on budget for scheduled first gold in Q3 of this year and with the GC drilling results confirming our starter pit grades, we believe our outlook for a successful production ramp-up has markedly improved."
Grade Control Drilling Program
The maiden GC drilling program at the A1 starter pit was recently completed in preparation for mining. Drilling was aimed at upgrading the confidence level in both the geological interpretation as well as the gold grade estimation in the upper 24 m of the deposit. This current and ongoing GC program is designed to cover the first 12 to15 months of the scheduled process plant feed.
The GC drilling was completed on a 12.5 m by 12.5 m pattern over the pit area. The GC program has confirmed the widths of the high-grade gold ore zones, generally 15 m to 20 m wide and in some places, up to 40 m wide, within the A1 starter pit. The majority of cross-sections have returned significant zones of thick high-grade oxide gold results.
These results provide further confidence in both the widths and tenors of mineralization present at A1 prior to the commencement of scheduled mining and processing.
Drilling on-site continues with the RC drill rig now mobilized and operating at the A2 open pit area.
A summary plan map of the reserve blocks in the A1 pit prior to the GC drilling is presented in Figure 1 while Figure 2 shows the same blocks as informed by the successful GC drilling.

QA/QC
The mineralized intervals are based on a lower cut-off grade of 0.28 g/t Au, a minimal width of 2 m and up to a maximum of 2.0 m of dilution being included. The true width of the mineralization is approximately 85% of the drilled length. The A1 Pit grade control samples were collected by employees of Orezone Bombor? SA ("OBSA"), Orezone's 90% owned subsidiary that owns the Project, using either a Reverse Circulation (RC) rig from JMS Drilling Sarl equipped with two cyclones (50% of the program), or OBSA's RC rig equipped with either a Metzke automatic sampler (3% of the program) or with one cyclone followed by division using a rotary sample divider (47% of the program). The average weight of the samples collected with all three methods was 2.0 kg. All samples from this program were dried and pulverized at the OBSA sample preparation site facility operated by SGS Burkina Faso Sarl. A 1 kg aliquot was analyzed for leachable gold by bottle-roll cyanidation using a LeachWell tm catalyst either at BIGS Global Burkina Sarl in Ouagadougou (60% of the program) or at SGS Burkina Faso Sarl in Ouagadougou (40% of the program).
Orezone employs a rigorous Quality Control Program including a minimum of 10% standards, blanks, and duplicates.
