DAR ES SALAAM, TANZANIA, Feb. 4 /CNW/ - Harp Sangha, CEO/President of
Douglas Lake Minerals Inc. (DLKM-OTCBB/Franfurt-D60.F
www.douglaslakeminerals.com) announces that preliminary gemological results
have confirmed the presence of diamondiferous alluvial gravels from the
company's Magembe diamond property in the Shinyanga District of northwestern
The exploration at Magembe is being conducted under the terms of an
option agreement with Canaco Resources whereby Canaco can earn 75 per cent
interest in the property through cash and share payments and spending
$2.5-million (U.S.) in exploration expenditures over four years (see Canaco
news in Stockwatch on March 9, 2007).
The sampling of Magembe alluvial gravels was conducted as part of Phase I
exploration, the objective of which was to confirm and evaluate indicated
diamond potential from both alluvial and kimberlitic sources.
To date, 60 samples weighing a total of 12.4 tonnes have been processed
from a total 45.9 tonnes of alluvial gravels from 220 samples collected in
2008. A total of 41 diamonds and diamond cleavages have been recovered from 12
of the 60 samples, with the largest stone weighing 0.22 carats. Importantly,
the positive results are evenly spread over the sample region confirming the
presence of diamondiferous gravels within the 900 metres by 100 metres area
from where the processed samples were collected.
Of note is the fact that the recovered diamonds represent two distinct
populations with respect to degradation, indicating two different sources; one
proximal and one distal. The provenance of the recovered diamonds cannot be
identified with certainty; however, the alluvial gravels of the Magembe
property lie 5km south east of the Williamson (Mwadui) diamond pipe. Other
diamondiferous pipes are known from the Shinyanga region based on government
research, including four interpreted kimberlite targets on the northern
portion of the Magembe property.
The Magembe property is part of a two-kilometer buffer zone created to
surround the Williamson (Mwadui) mine as part of the original mine development
in the 1940s and 50s. This buffer zone was formed with the intention of
ensuring that the mining operations could proceed in a safe and orderly manner
through the prohibition of the mining of surficial diamond deposits in the
area immediately adjacent to the mining operation.
The Williamson mine is owned 75 per cent by De Beers and 25 per cent by
the government of Tanzania and is currently the subject of a negotiation to
purchase the mine by South African based Petra Diamonds. The mine has a
production history that spans six decades. The Williamson pipe covers 360
acres and, at the time of its discovery in 1940, was considered the largest
economically exploitable pipe in the world. The mine at Williamson is notable
as the original source of pink diamonds and has produced notable stones
including a 54-carat flawless pink diamond and a 388-carat diamond found in
The 60 samples were processed to heavy mineral concentrates by Seamic
laboratories (an affiliate lab of SGS) in Dar es Salaam, Tanzania. The heavy
mineral concentrates were processed using gemological methodologies for
diamond recovery and identification in the laboratory facility of True North
Gems in Vancouver.
The processing of the remaining 160 samples is ongoing and results will
be reported as they become available.
The planning, execution and quality control programs at the Magembe
diamond project are under the supervision of Andrew Lee Smith, P. Geo. Mr.
Smith is a qualified person as defined by National Instrument 43-101. The
gemological assessment of the heavy mineral concentrates in Vancouver was
completed by John Mattinson, B.Sc., G.G.
