Diamond
Exploration, Mali
In 2003 Nevsun Resources
(Mali) Ltd. acquired a 170 km2 diamond
exploration license which surrounds, and includes Nevsun's
Tabakoto and Segala properties. The Kenieba Region of
Western Mali has been known to be a diamoniferous kimberlite
province since the 1950's and is known to have produced large
sized diamonds of commercial quality from both alluvial and hard
rock sources. In the past, diamond finds of up to 232
carats have been documented within the region and 24 kimberlite
occurrences are known.
Nevsun has conducted diamond exploration since the
acquisition of the permit in 2003 which has advanced through a
number of stages from archival research and project concept
generation to soil and stream sediment sampling, and ground
magnetic surveys. Kimberlite and loam samples from shallow pits
excavated on selected targets were processed for major element
mineral analysis of kimberlite indicator minerals. Nevsun
now has the most comprehensive kimberlite indicator
database for the area and results
from the analyses show that two target areas appear to have
sufficient potential to host diamonds, as well as identified
eight further targets for follow up work.
In July 2006, the Company announced a pooling agreement with
African Metals. Please see our
News Release of July 5, 2006
for details.
