The aim is to test approximately eight kilometres of strike, consisting of hard-rock artisanal mining, anomalous geochemistry and coincident magnetic anomalies.
The company will undertake approximately 6,500 metres of air core drilling and approximately 1,500 metres of deeper reverse circulation drilling.
Historical drilling results from 2008 included 2.2 grams per tonne gold over 21 meters.
The hard-rock artisanal workings at Zaranou occur within a broader 40 kilometre by 2.5 kilometre-to-five kilometre wide alluvial gold mining corridor, coincident with a major regional magnetic contact.
"The team has done a great job in completing drill planning, community consultation and drill access construction in time for the arrival of the Geodrill rigs, whilst continuing mapping, soil sampling and drone survey field activities,” said Len Kolff, chief operating officer of IronRidge.
"We are excited to get the drill programme underway, to test below the extensive hard-rock artisanal mining zones with high-grade channel sampling results, as well as discrete magnetic anomalies spatially associated with the mineralised structures targeted by the artisanals. It is a challenging task, as the area is vast, with over 40 kilometres strike of alluvial workings,” he added.
