TORONTO, April 6 /CNW/ - SouthernEra Diamonds Inc. ("the Company") (TSX:
SDM, AIM: SRE) announced today that ground follow-up of kimberlite targets
generated from recent airborne geophysics is returning positive kimberlitic
sampling results. Additionally, the Company announced that it has commenced
alluvial diamond testing within the first of its seven separate alluvial
projects in the Democratic Republic of the Congo (DRC).
Since 2003, SouthernEra has secured a large and outstanding portfolio of
exclusive diamond exploration permits covering 13,614 square kilometers
located within the diamond-rich Kasai Provinces of the DRC. The majority of
the permits lie within a 'kimberlite emplacement corridor', which is underlain
by Archean basement granite-gneiss of the Congo Craton, and extends from the
DRC southwest into the renowned diamond producing Lunda Norte Province in
neighboring Angola, which hosts the massive 23.2 million carat Camafuca
kimberlite complex in which the Company has an 18 percent free-carried
interest. This corridor is considered the world's most prospective and largest
new diamond exploration opportunity. The known kimberlites in this region are
of exceptional size and grade, and the potential for new diamondiferous
kimberlite discoveries in this region of the DRC is rated very high.
Last October, SouthernEra completed over 43,000 line-kilometres of
airborne magnetic and radiometric geophysical surveys under contract with
Fugro Airborne Surveys (Pty) Ltd. The surveys covered 21 of SouthernEra's
41 exclusive diamond exploration permits in the DRC. These 21 permits
collectively comprise three separate primary kimberlite project areas; known
as the Kito, Nyota and Akiki blocks. These three project areas are focused in
the diamond-rich Kasai-Oriental Province, which has produced two of the
'top-ten' largest gem quality diamonds in the world and in the mid-1980's was
producing up to 20 million carats of diamonds per year.
The geophysical data was integrated and merged with composites from
satellite imagery and has to date generated 34 high priority targets and
numerous moderate priority targets which, from their magnetic signature,
resemble kimberlite pipes. The diameter of each of these bodies is estimated
from 170 to 750 meters. Of the 34 high priority targets about half are classic
dipolar anomalies.
Independently, the selected targets have been compared with detailed
historical data relating to diamond finds and production recorded by companies
producing diamonds before the DRC's independence in the 1960's, as well as
with current informal digging activities. This comparison has revealed the
proximity of some the airborne targets to known alluvial reserves, indicating
that they could potentially be the source rocks for the alluvial diamond
occurrences.
In the Kito Block, which is centered on a region where diamonds are both
of high quality and value, a number of the nineteen identified targets are
also encouragingly close to areas of known alluvial diamond production. The
Nyota Block has yielded two out of eight identified targets, which coincide
almost exactly with proven high grade alluvial reserves (up to 29 carats per
cubic meter), and three more targets appear very well positioned as potential
sources of the alluvial diamonds. Informal artisinal diamond digging is
widespread throughout this area, with one target located less than 200 meters
upslope of current colluvial workings. Within the Akiki Block, stream samples
collected by SouthernEra have returned kimberlitic indicator minerals
(including several unique suites of kimberlitic ilmenite) immediately
downstream of the seven identified airborne targets.
The regional and detailed site-specific stream and soil sample follow-up
of the aeromagnetic survey targets is progressing as scheduled. Ground
geophysical surveys to further define high interest airborne targets are set
to commence.
In addition to the above primary kimberlite projects, SouthernEra has
also secured high interest alluvial diamond permits within the
Tshikapa/Kasai/Luebo alluvial diamond field in the Kasai-Occidental Province,
and also within a second major alluvial diamond field in the Kasai-Oriental
Province (actually located within the Nyota project area). These permit areas
collectively constitute seven separate major alluvial projects. Following a
review of the alluvial diamond potential within these permit areas, a
SouthernEra exploration base has been established in the town of Tshikapa,
which will become the center of feasibility studies into SouthernEra's
alluvial projects in the Kasai Occidental Province.
The Belgian mining company, Forminière, extracted approximately
14.5 million carats from the Tshikapa region up until 1955 mainly from
mechanized mining of terrace deposits. This area has historically produced the
highest value diamonds reported in the DRC. Current alluvial active channel
dredging operations occur both upstream and downstream outside of the
SouthernEra permits, as well as active artisinal terrace mining. SouthernEra's
diamond recovery equipment has been transported to this region and testing of
the first of the seven separate alluvial diamond projects has commenced with
encouraging early results. Following the assembly and commissioning of a
gravel suction dredge and recovery plant during the next few weeks, evaluation
of the active river channels will commence to determine the nature of the
diamond deposits and best mining method.
In addition to the active river channels, significant diamond potential
occurs within large alluvial flats within the permit areas. A systematic
seismic geophysical program will commence within weeks to define the bedrock
topography beneath the alluvial flats in order to establish the locations of
paleochannels which are expected to host high grade concentrations of gravel
within the alluvial flats system. Following the completion of the geophysical
surveys and interpretation of the results selected areas will be evaluated by
Banka drilling, pitting and bulk sampling. The potential of the alluvial
terraces in the project area will be investigated later this year.
In June 2003 the DRC Mining Registry (Geological Survey) was opened for
the first time under the new World Bank-sponsored Mining Code (Law 007/2002).
The new Mining Code has encouraged renewed interest on the part of diamond
mining and exploration companies in the DRC, including the major producers De
Beers and BHP-Billiton. The implementation of the new Mining Code, led by the
Ministry of Mines and the Mining Registry, has been carried out in an
encouragingly efficient and transparent manner. In the case of diamond
exploration, the Mining Code gives permit holders exclusive rights for a
period of four years, renewable for two additional two-year periods. On
discovery of an economic deposit, the holder can automatically apply for a
mining permit.
Mr. Uwe Naeher, Professional Geologist, is the qualified person under NI
43-101 responsible for the technical information in this release. All stream
and soil samples collected for the recovery of kimberlitic indicator minerals
are processed at SouthernEra's in-house diamond laboratory located in
Polokwane, South Africa.
The DRC is one of five countries in which SouthernEra is engaged in
advanced diamond exploration. Others include Canada, South Africa, Gabon, and
Australia. This represents the fourth most active global diamond exploration
program after the majors DeBeers, BHPB and Rio Tinto. The Company also
operates the Klipspringer Diamond Mine in South Africa and maintains an
18 percent free-carried interest in the Camafuca Diamond Project in Angola.
Some statements contained in this news release are forward-looking and,
therefore, involve uncertainties or risks that could cause actual results to
differ materially. Such forward-looking statements include comments regarding
exploration work. Actual results could differ materially from those
anticipated. The Company disclaims any obligation to update forward-looking
statements.
