Orapa Project Update- Bulk Sampling Progress
Tawana Resources NL ("Tawana") has been advised by its joint venture partner,
Nowak Investments Pty Ltd ("Nowak") that bulk sampling excavations on the Orapa
Project BK24 kimberlite have progressed well since commencement in late April.
Nowak has also advised Tawana that the mineral chemistry of kimberlitic
indicator minerals recovered from 2007 drill samples of BK24 is highly
encouraging. The presence of a significant number of G10 garnets gives a strong
indication that this diamondiferous kimberlite is likely to yield an encouraging
Nowak is excavating three vertical shafts into BK24 to access fresh kimberlite,
below the basalt breccia zone, at approximately 30m below surface.
The first shaft has reached the 30m target depth from surface and has penetrated
The second shaft is currently at 26.5m depth from surface and has not yet
penetrated kimberlite and is being continued to the 30m target depth.
The third shaft is at 12.7m depth from surface and intersected kimberlite
breccia. Excavation of this shaft had been stopped temporarily until the other
two shafts have been completed.
Nowak is planning to collect 100t of kimberlite from each shaft by excavating
the material from 4 five metre tunnels dug radially from the base of each shaft
at the 30m level.
A Dense Media Separation (DMS) plant has been set up in Francistown, Botswana,
in readiness for the processing of the BK24 kimberlite samples, which is
expected to commence in late June.
At a recent Joint Venture meeting it was agreed that the BK22 and BK23
kimberlites would also be targeted for bulk sampling. Drilling conducted in
2007 suggests that these 2 kimberlite pipes are in fact joined and represent a
single pipe with an approximate surface area of 2.2ha.
The results of the current bulk sampling on BK24 will determine the scale and
scope of future bulk sampling operations.
Soil sampling by Nowak in the Moshaiwa area has commenced. The two areas
targeted during this sampling program are areas in which previous explorers
reported diamonds from soil samples during the 1970`s. The source of these
diamonds has not been located, but geomorphologic interpretation by Nowak
suggests that there may be at least two diamondiferous sources in the area. The
diamonds plot along strike of a dolerite dyke swarm, with which several
kimberlites are associated in Botswana and Zimbabwe.
Under the terms of the agreement Nowak is required to conduct and sole fund the
following program to earn a 51% interest in the project:
Review all the results from the work completed by Tawana.
Select kimberlites for mini-bulk sampling at the 30 metre level. The Management
Committee, comprising members from Tawana and Nowak, will determine the selected
Excavate at least one pit per selected kimberlite to a depth of 30 metres.
Excavate from horizontal drives at the 30m level no less than 100 tonnes of
kimberlite for processing from the selected kimberlites less than 1 hectare in
surface area and no less than 200 tonnes of kimberlite from the selected
kimberlites greater than one hectare in surface area. A maximum of 1100 tonnes
of kimberlite will be excavated for processing during this initial phase. If
warranted additional bulk sampling up to 3000 tonnes per kimberlite could be
excavated and processed in subsequent phases.
Nowak has also undertaken to conduct exploration on the Borolong and Moshaiwa
projects, which are located relatively close to the Orapa tenements.
At the completion of the above program, Tawana will have the option to
contribute 49% of ongoing expenditure or allow Nowak to continue sole funding to
earn 70% interest in the projects by completing a bankable feasibility study.
Thereafter both parties will contribute pro-rata to expenditures.
Location and Background
The Orapa kimberlite field is located in north eastern Botswana, and includes
the Orapa, Letlhakane and Damtshaa diamonds mines, which produce in excess of 13
million carats of diamonds per year. These mines are owned by Debswana Diamond
Company (Pty) Limited. The Orapa kimberlite field is one of the largest
diamondiferous kimberlite fields in the world, containing 79 known kimberlites,
of which the majority has been proven to be diamondiferous. The Orapa mine is
one of the largest producing kimberlites in the world and is 113 hectares in
The Orapa mine is located 20 km to the west, Letlhakane is 30km to the south,
and Damtshaa is 6km to the south of the Tawana licence.
