Gold developer West African Resources Limited (ASX: WAF) has announced highly positive final assay results from the maiden grade control reverse circulation drilling program at its M5 deposit at the Sanbrado Gold Project in Burkina Faso.
Significant M5 GC results include 29m at 13.2 g/t Au from surface, including 18m at 18.2 g/t Au from 11m; and 28m at 6.2 g/t Au from surface, including 13m at 11.3 g/t Au from 4m.
WAF noted that the close spaced GC drilling confirms interpretation and grade estimation in the M5 gold resource.
The company said that the first pass GC at M5 has been completed and the drilling is on-going at M1 South.
WAF announced that the construction activities at Sanbrado remain on budget and schedule, and the first gold pour is on track for Q3 2020.
Sanbrado gold project
Sanbrado Gold Project is a high-grade gold discovery located ~90km east-southeast of Ouagadougou, the capital of Burkina Faso in West Africa.
The current Sanbrado Gold Project MRE is 39.4Mt at 1.9 g/t Au for 2.41Moz Au (Indicated), and 15.7Mt at 1.3 g/t Au for 0.68Moz Au (Inferred).
The Sanbrado project consists of Mankarga 1 North (M1 North), Mankarga 1 South (M1 South), Mankarga 3 (M3), and Mankarga 5 (M5) deposits.
The company reported that a maiden GC drilling program has recently been completed at the M5 deposit, ahead of the start of mining of the stage 1 open pit in Q1 2020.
GC drilling program at M5
WAF said that the maiden Grade Control Drilling Program at M5 was aimed at upgrading the confidence level in both the interpretation as well as gold grade estimation in the upper 20m of the deposit.
This program covers the first 6 months of scheduled open pit ore from M5. WAF said that the GC holes drilled to date at M5 have targeted early production tonnes from near surface mineralisation within the M5 stage 1 oxide open pit.
The company reported that the drilling was completed on a nominal 12.5m by 12.5m pattern over the stage 1 pit area, with two areas of tighter spaced 12.5m by 6.25m spaced drilling to test the independently prepared April 2019 Mineral Resource Estimate.
West African Resources said that the GC program has confirmed the width of gold ore zones, generally 30m to more than 50m wide, within the M5 starter pit.
Excellent results from RC drilling
The company reported that the majority of cross-sections have returned significant zones of thick high-grade oxide gold results from surface at M5.
Significant M5 GC results include:
- 29m at 13.2 g/t Au from surface, including 18m at 18.2 g/t Au from 11m;
- 28m at 6.2 g/t Au from surface, including 13m at 11.3 g/t Au from 4m;
- 20m at 7.8 g/t Au from surface, including 3m at 41 g/t Au from 16m;
- 25m at 6.2 g/t Au from surface, including 15m at 9.6 g/t Au from surface;
- 29m at 5 g/t Au from surface, including 3m at 19.1 g/t Au from 4m; and
- 23m at 5.6 g/t Au from surface, including 6m at 16 g/t Au from 3m.
The company said that the results confirm extensive wide zones of soft free milling oxide ore of between 30 to 60m wide which are expected to form the bulk of the mill feed during the commissioning and the first 6 months of production.
The company said that the follow-up infill drilling has been planned and will be completed once drilling at other open pit areas has been completed. Currently, drilling is ongoing at the M1 South open pit area.
WAF announced that it is fully funded with construction underway which is currently 30% complete. The company said that the first gold pour is on track and is scheduled in Q3 2020.
WAF’s Managing Director Richard Hyde said: “Final results from the maiden control program at M5 have returned further high-grade oxide results including 29m at 13.2 g/t Au.
Results from our first grade control program confirms we will commission the Sanbrado mill on soft high-grade oxide ore from surface from the M5 open-pit.
We are fully funded, with construction progressing on time and budget. First gold pour is on track for Q3 2020.”
