Namwele Test Pit Results
Edenville Energy is pleased to announce positive results from
the first set of detailed coal sampling and test work at the
Namwele deposit, part of the Rukwa Coal Project, near Sumbawanga in
Western Tanzania.
During the past three months, test pits were dug to a depth of
approximately 3 metres at the Namwele, Mkomolo and Muze deposits,
collectively known as the Rukwa Coal Project, and the samples
analysed for quality. The test results from Namwele are presented
below, with further sampling analysis from Mkomolo and Muze
expected to be announced by the end of 2014.
Four test pits were excavated at Namwele to expose the near
surface coal seam, better defining the coal that could be extracted
in the initial stage of mining operations. For near surface coal
seams, test pitting is the most common, efficient and effective way
of gathering data, not only quicker and less costly than a drill
programme but also allowing a specific coal seam to be exposed,
examined and sampled more thoroughly. The excavation and sampling
work was carried out by Edenville personnel with full quality
control processes and procedures in place.
This near-surface coal seam has an average thickness of 2.0m and
was sampled to a maximum depth from surface of 4m, with an average
depth from surface of 2.56m. The four test pits were distributed
along a total strike length of approximately 870 metres through the
Namwele deposit.
The samples from these four test pits at Namwele have been
analysed at Alfred H Knight's laboratory in Scotland, UK. Alfred H
Knight ("AHK") is a highly respected analytical laboratory group
that specialises in metals and minerals testing, with particular
expertise in coal. It is ISO 9001:2008 accredited and operates in
35 countries carrying out a wide range of test work on coal and
other fuel sources.
The results shown in Table 1 below show the combined raw coal
analysis and the washed results at a Relative Density ('RD') of 1.7
for the Namwele test pits.

Of specific note is the yield of over 50% from the latest wash
tests at a relative density of 1.7, which produced an average
22.6MJ/kg product. The original wash tests on the Namwele resource,
cited in the Geological Modelling and Resource Estimation for the
Rukwa Coal Project dated March 2013 returned a washed yield of
11.6%, albeit on a global basis over the entire coal measures.
The recent test pit samples averaged a raw energy value of
14.39MJ/kg compared to a previous global value of 6.8MJ/kg in the
original drill samples at Namwele, again described in the above
report.
Sulphur and ash varied over the test pits with sulphur washing
out to 1.7% in some areas whilst remaining above 3% in others.
Washed ash averaged 22.27% being reduced to as little as 18.6% in
some samples. A degree of selective mining and blending would be
envisaged to give a consistent coal product.
Putting these test pit results in context, the improved coal
quality applies to the uppermost, near surface seam, whilst the
original resource values apply to the entire coal measures both
laterally and vertically. We are, however, very encouraged by these
positive results in the top seam of three at Namwele.
The results indicate high quality, near surface coal is
available in the Namwele area. The utilisation of selective mining
techniques to extract this coal may bring improvements in the
quality of available feedstock for a Thermal Power Plant and also
provides the basis for the detailed investigation into the
potential to sell higher quality coal directly into the local and
regional markets.
Rufus Short, CEO of Edenville Energy commented: "We are very
encouraged by the positive results returned from our Namwele test
pits. They show the Namwele deposit has the possibility to provide
significantly higher quality coal and a higher washed yield than
previously modelled. This could improve the technical and economic
parameters for the coal-to-power development and also forms the
basis for a detailed investigation into potential coal sales to the
regional market. The testwork on the Mkomolo and Muze deposits is
well underway and we will update our shareholders as the results
become available".
