Nangodi and Yameriga
- Nangodi Main is Abzu’s principle target among numerous drill-ready targets.
- Nangodi Main features mineralized intercepts within a zone 1.2 km long up to 60m wide
- past gold production at ~26 g/t gold
- key geologic location
Abzu has two concessions, Nangodi (142 km2) and Yameriga (74.18 km2) in the Bole-Nangodi Belt (Figure 1). These concessions host the most advanced targets among the portfolio of 10 concessions currently under option agreement with Red Back Mining Ghana Ltd, a wholly owned subsidiary of Kinross Gold Corporation. Numerous targets ranging from soil anomalies to drill intercepts have been identified by past explorers (Figure 2).
The concessions possess targets at various stages of definition ranging from robust untested gold-in-soil anomalies to multi-meter, multi-gram gold intercepts in drill holes. The concessions lie along three of Ghana’s major gold-bearing belts; the Bole-Nangodi, the Sefwi, and the Ashanti Belts, and significantly expands Abzu’s portfolio to more than 1,100 km2 from 350 km2. Addition of these concessions to Abzu’s portfolio distributes Abzu’s exploration opportunity over a strategic range of geologic environments and places Abzu as one of Ghana’s leading explorers in terms of landholding size.
Abzu is focused on the Nangodi Main target where gold in quartz stockwork and veins was previously evaluated by Africwest drilling in the mid-1990s. It is also the site of a 1930’s vintage underground mine that produced gold at an average grade of ~26 g/t gold (Dennis, 1947; Griffis and Ageezo, 2000) (Figure 3). Historical drill intercepts have intersected gold mineralization along a strike distance of 1.2 kilometres with true widths up to 60m (Figures 4, 4-2). Mineralization is currently open in all directions. Bedrock artisanal mining along this zone currently recovers gold (Figure 5).
The Nangodi Main and other targets align along a regional shear zone that continues to the northeast across the border into Burkina Faso where it hosts the Youga Mine of Endeavor Mining Corp. Gold mineralization at Nangodi Main occurs in a steeply northwest-dipping tabular zone associated with shearing within felsic rock and at the shear contact with surrounding sedimentary rocks. Mineralization is open in all directions.
