African Iron intersects more DSO from surface at Mayoko Iron Ore Project
Friday, October 21, 2011
African Iron (ASX: AKI) has returned further significant direct shipping ore (DSO) assay results from its resource definition drilling program at its 92% owned Mayoko Iron Ore Project, located in the Republic of Congo, West Africa.
Highlights from the second batch of results include:
- 75 metres at 58.4% iron;
- 30 metres at 56.7% iron;
- 21 metres at 59.3% iron; and
- 12 metres at 61.7% iron.
These results continue to confirm the grade and thickness of the DSO cap, and increase the confidence in the continuity of the iron mineralisation.
All the above results are from surface and drilling has also confirmed the presence of high-grade detrital ore of up to 20 metre thick on the flanks, and at the foot, of Mt Lekoumou.
Drilling is continuing with five rigs currently active (three reverse circulation and two diamond) and independent consultant Golder Associates remains on track for the completion of an interim JORC Resource update.
The 30,000 metre resource definition drilling program is targeting the enriched weathered zone of a substantial banded iron formation (BIF) at the Mount Lekoumou and Mount Mipoundi prospects.
The program aims to upgrade and expand the existing Inferred Mineral Resource of 33 million tonnes of predominantly DSO hematite ore at 55.6% Fe.
Drilling also aims to define a maiden resource for the underlying bedded zone of supergene enriched BIF, which can readily be beneficiated with crushing, screening and conventional dense media separation/gravity techniques to produce DSO fines.
Highlighting the potential of Mayoko, the project has an exploration target of DSO hematite and bDSO (enriched BIF)of 320 to 520 million tonnes at 40-65% iron, with a magnetite BIF of 1.3 to 2.1 billion tonnes at 30-36% iron for a total of 1.6 to 2.6 billion tonnes at 30-65% iron.
First production is forecast for mid-2013, with the product range DSO lump and fines, bDSO hematite fines and magnetite concentrate.
The mine life includes an initial 10 year mine life based on 50 million tonnes DSO hematite target at 5 million tonnes annually, with production extending to plus 20 years with bDSO.
Ends.
