As well as the indicated 470,000 tonnes grading 26.4gpt, there is an additional 350,000t at 16.1gpt (for 180,000oz) in the inferred category.
The two estimates comprise the current resources anticipated to be mined via an underground development, with the open pit resources to 120m depth totalling 800,000t at circa-6.68gpt for 172,000oz.
In sum, M1 South totals 1.6 million tonnes grading 14.4gpt for 747,000oz, with mineralisation remaining open at depth.
That helps take global resource at West African’s Sanbrado project past the 2.5 million ounce mark, with indicated resources at M5 put at 35.9Mt at 1.3gpt for 1.46Moz – with another 410,000oz in the inferred category.
Another resource estimate is pegged for next quarter, ahead of an updated feasibility study in the second quarter of 2018.
Rig activity at the project is again about to be ramped up as the wet season passes, with a doubling of drills in operation to six next month.
