Genmin drilling intersects iron oxide mineralisation at Banjougoy target

Drilling has confirmed the scale and resource growth potential of Genmin’s latest iron prospect within the Baniaka project.

West Africa-focused explorer Genmin (ASX: GEN) has intersected oxidised iron mineralisation at the Bandjougoy prospect within its wholly-owned Baniaka project in the Republic of Gabon.

The company made the hit beneath the project’s detrital iron deposits (DID) during diamond drilling of 25 holes for a total 3,000 metres.

The results are believed to have confirmed the scale and resource growth potential of the prospect.

The first six drillholes for 522.5m targeted the down-dip extension of iron mineralisation within an existing drill section and tested the possibility of deeper oxidation and iron enrichment along an interpreted structure on a newer section.

Genmin intercepted oxide and primary mineralisation at the downhole depths which were forecast during drill planning and confirmed the presence of a large-scale, flat-lying mineralised system at or near surface.

Key oxide (comprising soft oxide and intact oxide material) intervals were 31.3m at 44.4% iron from 10.3m; 49.1m at 40.9% iron from 7.5m; and 40m at 40.9% iron from 3m.

The soft oxide sits immediately below the DID in Bandjougoy’s geological profile and is typically finer, with more material reporting to be less than 1 millimetre size fraction.

Banded iron formation target

At 4.4km long with an unfolded strike extent of 6.3km of banded iron formation (BIF), the Bandjougoy prospect is the single largest drill target for oxide mineralisation at Baniaka which does not have a current mineral resource estimate.

The prospect’s significance has been highlighted by an in-situ oxide exploration target of between 67-124 million tonnes and grading between 35% to 49% iron.

Genmin’s drilling confirmed the shallow northerly dip of the BIF which hosts the main mineralisation at Bandjougoy, as well as a true BIF thickness of up to 60m.

The primary BIF mineralisation remains open at depth on both drill sections and represents a strategic target to define a significant underlying magnetite asset at the prospect.

Single geological model

Genmin aims to consolidate the Bandjougoy and Tsengué prospects at Baniaka into a single geological model to calculate a mineral resource estimate with a minimum indicated classification.

When combined with the Flouflou and Bingamba North prospects, the calculations will form the focus of activity for resource estimations relating to Baniaka’s preliminary feasibility study.
