MCA
The Mineral Cooperation Agreement ("MCA") property in western Liberia, covering 15,000km2, is a contributory Joint Venture between the Government of Liberia (30%) and Mano (70%) and incorporates the rights to explore for diamonds, gold and base metals.
In January 2005, reconnaissance stream sampling commenced in the MCA, focussed on the Camp Alpha area. Over 150 samples have been collected so far (April 2005), with a large number of these having been processed in Mano's recently established diamond prep laboratory in Monrovia. Many of these samples yielded abundant kimberlitic indicator minerals, particularly ilmenite and garnet.
Subsequent microprobe analysis in South Africa of selections of these grains confirms their kimberlitic affinity, but furthermore suggests a very high interest source (or sources) based on the garnet mineral chemistry (see Plot 1). The chemistry displays a significant population of high Cr2O3 and low CaO garnets that is considered to bear comparison with some of the best garnet chemistry seen elsewhere in the world, and is indicative of diamondiferous sources within the MCA property. This is supported by the fact that the Camp Alpha area has been subjected to intensive artisanal diamond mining activity.
Mano's immediate objectives are to continue the reconnaissance sampling progress, and secondly to investigate in detail these high interest anomalies with a view to locating the kimberlite source(s) that are believed to be present within our property.
