- SUCCESSFUL GROUND PENETRATING RADAR SURVEY REVEALS PALEO-CHANNEL
- ADDITIONAL KIMBERLITES CONFIRMED
- ADDITIONAL DIAMONDS RECOVERED FROM THE PROPERTY
- BULK SAMPLING PROGRAM PLANNED
SOURCE FOR ALLUVIAL/PLACER DIAMONDS POSSIBLY NARROWED TO FIVE
TORONTO, Nov. 13 /CNW/ - Randsburg International Gold Corporation
(TSX-V:RGZ) announced today an update to its Victory Strike diamond project.
The Company has been engaged in an evaluation of possible extensions of the
historic alluvial and placer operations on the southern portion of the
property. As well, the Company has continued to search for the kimberlite
source of the diamonds on the property. As a result of work conducted on the
Company's concessions, the Company plans to undertake a bulk sampling program.
Randsburg's Brazilian subsidiary, DIADEM MINERACAO LTDA, has a 100%
interest in the exploration permits that cover the prospective area of 526.6
square kilometres (130,124 acres). Randsburg owns 85% of the subsidiary. The
concessions extend to within 150 metres of the famous diamond producing area
of the Verissimo River from which diamonds have been recovered for more than
100 years including the famous Goias diamond, discovered in 1906 and weighing
The work has been conducted under the direction of the Company's Chief
Geologist, Dr. Ken Germundson, P. Geo and Company Director Bill Jarvis, who is
overseeing the Company's Victory Strike diamond exploration project in Brazil.
Mr. Jarvis joined the Company as a Director in May of this year and began work
at the Victory Strike project this past summer. Mr. Jarvis has 30 years of
diamond exploration experience.
In September 2007, a test of the Ground Penetrating Radar (GPR) method
was conducted by an independent Brazilian Company on two small grids (grids 1
and 4) at two locations on the Victory Strike Property. The test was to
determine the applicability of the method in this geological setting. The test
is regarded as a success and more use of Ground Penetrating Radar is planned.
Grid 1 was established in the southern part of the property along side of
existing garimpeiro mining of terrace gravels located along the west side of
the valley of the Vai Vem River, which crosses the entire property in a
north-south direction. The grid consists of 300 metres of base line and 1,050
metres of cross-lines that are spaced 50 metres apart. The limits of the
buried gravel bed away from and up slope from the workings have been
established. There is good definition of the alluvial sedimentary layers to a
depth of 8 metres with some readable penetration to 12 metres. An old river
channel, a paleo-channel is present within the buried and untested extension
of the gravel. The Company plans to evaluate the economic potential of the
buried gravels in this part of the property with a bulk sampling program.
Within the Grid 1 area, three samples of the gravels of 150 dry kilograms
each from the face of the garimpeiro workings have also been collected and
kimberlitic indicator minerals have been recovered. Bill Jarvis has stated
that, in his view, the surface textural characteristics of the kimberlitic
indicator minerals in the samples show that their source is local. If this is
the case and the direction of drainage has not changed, the source of the
diamonds in the gravels could be from kimberlites within the Victory Strike
Property. The property extends for 14 kilometres upstream from the gravel
deposit towards the north and drainages to the west comprise another 10 linear
kilometres of stream. Kimberlites have already been discovered within 3
kilometres of the Grid 1 alluvial gravel deposits.
A clear, white octahedral diamond weighing approximately 0.035 carats
with dimensions of 1.2x1.2x1 mm was recovered from the +1mm concentrate of a
stream sediment sample 500 metres downstream of kimberlite A40. The size of
the sample was 150 dry kilograms. The purpose of the work was to recover
kimberlitic indicator minerals as part of a kimberlite exploration program.
This kimberlite or perhaps one or two others (A38 and A39) discovered in the
area upstream, may be the source of this diamond.
Kimberlites are the most important source of primary diamonds in the
world. Many kimberlite pipes also produce rich alluvial or eluvial diamonds
The company's geologists believe that the source of the gravel deposits
and the gravels of the paleo-channel as defined by the GPR, is from the
smaller stream draining the A38, A39 and A40 kimberlite pipes and/or the
stream draining A34 and A74 rather than an old channel of the Vai Vem River.
The basins of the two streams drain areas underlain by quartzite-rich schists
which could be the source of the gravels. Both sets of kimberlites have been
emplaced along major normal faults. A40 is about 300 metres in diameter.
Three diamonds, now in possession of the Company, were recovered by a
garimpeiro on the east side of the Vai-Vem River on the Company's concessions
while the Company's geologists were working on the property in June. It is
unknown from what quantity of material these stones were recovered (pictures
of the diamonds will be posted to the Company's website at
www.randsburginternational.com). The diamonds are described as follows:
1 stone, clear white, brilliant, inclusion free, 2.38 carats, (rounded
stretched crystal shape, 8.3 x 6.1 x 4.9 mm)
1 stone, white with yellowish inclusion, broken macle shape, internal
fractures visible, 1.2 carats, irregular cleavage fragment, showing obvious
breakage, longest dimension 8.2 mm. There are indications that the stone was
considerably larger at one time.
1 stone, white with inclusions, 0.7 carats. Irregular broken shape, 5.9 x
4.2 x 3.6 mm.
More importantly, based on all of the work done to date on this part of
the concessions, including the GPR work in Grid 1 and further stream sediment
sampling, the Company's geologists believe that the source of the diamonds and
kimberlite indicator minerals being found on the western side of the river in
the garimpeiro gravels may be related to three kimberlites (A38, A39, A40) and
the source of the diamonds on the east side of this river may be related to
two geophysical anomalies (A34 and A74), now confirmed as kimberlites.
Significantly, no kimberlite indicator minerals have been found upstream from
A34. Also, such a scenario would provide an explanation for the absence of
other mined diamondiferous gravels elsewhere on the Vai Vem River. However,
the source for all of the diamonds found in the gravels could be one or more
of any of the above mentioned kimberlites.
The second GPR grid, Grid 4, centered in the northern part of the
property where diamonds were discovered by the Company in 2005 was designed to
look for buried deposits and channels (see www.sedar.com for all copies of the
Company's news releases). The GPR, in conjunction with auger drilling,
confirms that any layering evident is not related to alluvial action. The
Company is planning additional work in this area.
Additional use of Ground Penetrating Radar, to provide data for the
preliminary evaluation of other gravel deposits that are present on the
property are also planned along with extensions of the recently discovered
paleo-channel and historic garimpeiro workings. The applicability of the
method to define the size and shape of kimberlite discoveries will also be
The Company has arranged with an internationally recognized Corporation
that specializes in Ground Penetrating Radar to conduct a test GPR survey over
portions of the Company's concessions using this Corporation's new system. The
work will include additional work on the southern part of the Company's
concessions described above. This work is intended to further evaluate the
area described above as Grid 4 and to locate potentially unknown kimberlites
and kimberlitic dykes which may be the source of the diamonds discovered in
2005. This Corporation indicates that its new technology is able to see to
depths of 200 metres which is four to five times the penetration of previous
systems. In addition, the new technology provides at least double the
resolution of these previous systems. The new system has never been used in
Brazil to find or delineate kimberlites but has been used successfully
elsewhere. The field work for this test GPR program is expected to begin
before the end of the year. However, a confirmed start date has not been
established and additional time is required for the data to be interpreted.
