West African Resources Limited (ASX: WAF) has intersected extensive zones of free-milling gold mineralisation from recently completed resource definition drilling at its Toega deposit in Burkina Faso, with standout results including 79m @ 2g/t Au and 22m @ 5g/t Au intercepts.
Resource definition drilling at Toega
The company reports that a resource definition drilling program was completed at Toega deposit, located 14km southwest of West African’s own Sanbrado project. The program included an RC and diamond drilling program, as well as diamond core holes to provide geotechnical and metallurgical test work samples. A total of 118 holes were drilled for 15,514m.
“Resource definition drilling at the 1.3Moz gold Toega deposit has confirmed the geological model intercepting extensive zones of free-milling gold mineralisation”
Geological model confirmed
The resource definition drilling has now confirmed the geological model at the Toega deposit, developed by previous owners B2 Gold, with multiple holes intercepting mineralisation of similar geometry, grade, and tenor.
WAF reported that extensive gold mineralisation was confirmed in the main zone, with significant results including
- 79m @ 2g/t Au & 56m @ 1.6 g/t Au
- 22m @ 5 g/t Au
- 42m @ 2.4 g/t Au
- 29m @ 3.4 g/t Au
- 41m @ 2.3 g/t Au
The company reports that drilling also intercepted mineralisation near surface, outside of the USD$1,400/oz scoping study open pit shell, which is expected to be incorporated into future mining studies.
Potential at 1.3Moz Toega gold deposit
In 2020 West African Resources struck a $45m deal with Canada’s B2Gold and GAMS-Mining F&I to acquire the Toega gold deposit in Burkina Faso. The deposit is situated on the Nakomgo exploration permit, which is 90% held by B2Gold and 10% held by its partner GAMS-Mining F&I.
Toega includes a strike of over 1,200m, is up to 430m wide and has been drilled to a depth of 400m below surface. The project has an inferred mineral resource of 22Mt @ 1.9g/t Au for 1.3Moz Au at a cutoff grade of 0.5 g/t Au.
WAF has stated that it intends to bring Toega into the Sanbrado mine plan within three years, with the deposit expected to increase Sanbrado’s production profile and mine life.
A feasibility study, updated resource estimate, and maiden ore reserve are expected to be reported in Q1 2022.
West African Resources Executive Chairman Richard Hyde said: “Resource definition drilling at the 1.3Moz gold Toega deposit has confirmed the geological model intercepting extensive zones of free-milling gold mineralisation including 79m at 2 g/t gold and 56m at 1.6 g/t gold in drillhole NAK21-DD014. Social and environmental programs are progressing to plan, with the ESIA to be submitted to the government for environmental approval in Q4 2021. Geotechnical and metallurgical core samples have also been shipped to Perth for test work. The definitive feasibility study with updated resource estimate and maiden ore reserve for Toega is on track for release in Q1 2022.”
