London, 15 February 2010 Mwana Africa PLC ("Mwana" or the "Company") is pleased to announce an updated resource estimate for its 80% owned Zani-Kodo prospect in the Ituri Region of eastern DRC. The resource update follows resource modeling based on the 2,550m nine hole diamond core drilling program, completed in December 2009, on the depth extension of the Kodo Main zone, which is a portion of the 9km long Zani-Kodo Trend.
Mwana has defined indicated mineral resources containing 217 277oz gold and inferred mineral resources containing 421 013oz gold. This represents an increase of 14% and 61% respectively over the previous indicated and inferred resource estimates, announced on 2nd September 2009.In addition, the overall resource grade has been increased from 2.70g/t to 2.82 g/t.

The minimal variation (c.1%) in contained metal between 0.0g/t and 1.0g/t cut offs highlights the very well defined margins of the mineralized zone.
This drilling programme, completed on 1st December 2009, was designed to increase the inferred resource on the down-dip portion of the previously drilled resource to a maximum vertical depth of 380m. All 9 holes intersected mineralisation as expected . Summary assay results for these holes are reported below, and complete assay results will be posted on www.mwanaafrica.com.

These results, combined with geological observations from the drill core indicate the following:
Drilling recommenced in January, with a further 572m drilled to date. A second drill rig has now been mobilised to site. Drilling continues to target the continued down dip extension of the Kodo Main zone with the objective of rapidly increasing the resource. In addition down dip extensions of the Kodo North zone will also be drilled in order to extend resources in that portion of the mineralised zone.
The Kodo zone forms a 700m long segment of the Zani-Kodo Trend which has an overall strike length of 9km. See the news release of 10th December 2009 for more information on the Trend view (Update on Phase 2 diamond core drilling program at Kodo Main, Zani-Kodo Project, DRC)
Kalaa Mpinga, Chief Executive Officer of Mwana Africa, commented:
"We are pleased to be able to announce an updated resource estimate on our Zani-Kodo gold prospect. It is particularly encouraging that drilling just 9 additional holes has resulted in this substantial increase in indicated and inferred mineral resources, which indicates that our model is robust, and supports our confidence in the potential of the prospect. Mwana has so far only drilled 700m along an estimated 9km strike length along the Zani-Kodo Trend, but it is already clear that Zani-Kodo, together with the neighbouring Mongbwalu (AngloGold) and Kibali (formerly Moto Goldmines) concessions, could form one of the world's major undeveloped gold provinces."

This report contains information regarding the results of various exploration activities. Where a mineral resource has not been defined, it should be noted that the potential quantity and grade is conceptual in nature, there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resource.
