TSUMKWE DIAMOND PROJECT - NAMIBIA
Location: Ngamiland, Tsumkwe, Namibia
Owner: Mount Burgess Mining NL 90%, Kimberlite Resources (Pty) Ltd 10%
Project Location
The Tsumkwe Diamond Project is located on the north-eastern border of Namibia adjacent to the
Kihabe Base Metals Project and the Western Ngamiland Diamond Project in Botswana The project
surrounds the small town of Tsumkwe and covers an area of 6700km2 under 10 Exclusive Prospecting
Licences, seven of which are in Joint Venture with Kimberlite Resources (Pty) Ltd.
Regional Geology
The Tsumkwe Diamond Project is underlain by a variety of basement lithologies of Proterozoic and
granite-gneiss belts of pre-Damaran and Damaran age. The tenements are covered with a veneer of
Kalahari sands.
The Company believes the Tsumkwe Diamond Project has many attributes suitable for discovery of
kimberlite diatremes, which may host economic concentrations of diamonds, for the following reasons:





The Company has interpreted that the Project overlies the southern margin of the Congo-Angolan
craton providing the necessary deep cool mantle, suitable for generating kimberlites from within
the diamond stability field
The Project is situated south of the Trans-African Limpopo-Botswana Dolerite Dyke Swarm, at a
distance equivalent to the Orapa-Lethlakane Kimberlite Province in neighbouring Botswana
There is evidence of a long-lived, stable basement high composed of Pre-Damaran Orogeny aged
granite-gneiss which has been dated at >2,000Ma
Situated just south of the Sikeretti Kimberlites and south-west of the Nxau-Nxau kimberlite field in
Botswana
Non-diamondiferous kimberlites (Gura Kimberlites) have been discovered by the Company within
the project.
Exploration to Date
Exploration by the Company to date has involved the collection of 3700 loam samples, which were
processed for kimberlitic indicator minerals and drilling over 51,100m of percussion drilling to test
potential kimberlite targets and to sample the basal Kalahari contact for indicator minerals.
The basal drilling and surface loam samples have generated several distinct surface and subsurface
indicator mineral anomalies. These indicator minerals include 8 macrodiamonds and significant numbers
of G9 and G10 kimberlitic garnets, occurring in distinct clusters.
The Company believes that the freshness and sub-rounded state of some of these G9 and G10 garnets
is indicative of a short transport distance in the regolith and, thus, these indicator mineral anomalies are
in close proximity to as yet undiscovered kimberlitic sources.
Exploration Model
The Company believes that the known kimberlitic indicator anomalies can be constrained to discrete
palaeosurface domains defined by a series of subtle extensional half-grabens filled by the Kalahari
Sands and bounded by listric extension faults.
It is the interpretation of the Company that these listric faults bounding the sediment-filled grabens
represent zones of transcrustal weakness providing conduits for kimberlitic intrusives. As such, the
Company’s focus for ongoing exploration is to define the relationship of indicator mineral anomalies to
the palaeosurface and to nearby fault domains and grabens, and to back-trace the source of the
indicator minerals to kimberlite intrusions.
Initial success of this model has been the discovery of three non-diamondiferous Gura Kimberlites. The
Company believes that the presence of macrodiamonds and G10 garnets infers the existence of a local
diamondiferous kimberlite source.
Further Exploration
The forward programme to assess the diamond potential of the Tsumkwe Diamond Project revolves
around:



Imaging the palaeosurface and basement contours of the extensional half-grabens via magnetics,
drill testing and gravity surveys to refine transport directions for kimberlitic indicator mineral
anomalies
Targeted ground magnetic and gravity surveys over the upland sources of kimberlitic indicator
mineral anomalies
Drilling discrete kimberlite type magnetic targets as well as sampling the base of the Kalahari sand
cover in order to best assess the distances any recovered indicator minerals have travelled.

NORTH WESTERN NGAMILAND DIAMOND PROJECT - BOTSWANA
Location: North Western Ngamiland, Botswana
Owner: Mount Burgess (Botswana) (Proprietary) Limited (100%)
Project Location
The North Western Ngamiland Project granted in February 2009 is located on the north western border
of Botswana and adjoins the Company’s Tsumkwe Diamond Project in Namibia. Seven exploration
licences which are situated some 30km south of the Xau Xau kimberlite field cover an area of
approximately seven thousand square kilometres.
Regional Geology
Similar to the adjoining Tsumkwe diamond project area in Namibia the North Western Ngamiland project
area is located on the southern margins of the Angolan Craton and is underlain by basement lithologies
of Proterozoic and granite gneiss belts of pre-Damaran and Damaran age. A portion of the area has
been intruded by the Trans-African Limpopo-Botswana dolerite dyke swarm. A veneer of Kalahari
sands covers virtually the whole of the area.
Exploration Model
The Company believes that the North Western Ngamiland Project area has high potential for the
discovery of kimberlites for the following reasons:




The area is situated on the southern margins of the Angolan Craton.
The area is some 30 km south of the Xau Xau kimberlite field in Botswana and the western
borders are some 30 kms east of the Gura Kimberlites in Namibia.
A large portion of the area is situated within the Trans-Africa Limpopo-Botswana dolerite dyke
swarm, offering a potential zone of weakness for the intrusion of kimberlites.
There is a probability that one or possibly two of the G10 garnet anomalies found by the Company
in Namibia were sourced from the area now covered by the prospecting licences in Botswana and
transported into Nambia through an evident palaeo drainage.
Future Exploration
This area in Botswana was flown for aero-magnetics in 1998, which led to the discovery of the Xau Xau
kimberlite field, some 30 km to the north of the Company’s prospecting licences.
A number of aeromagnetic targets, displaying similar characteristics to kimberlite magnetic signatures
have been identified and are currently being surveyed by close-spaced ground magnetic surveys in
preparation for drilling. Some forty of these targets will be test drilled in an initial 2000 metre drilling
programme.
The Company believes that it is in an extremely advantageous position to have secured the grant of
these prospecting licences in Botswana as, together with its adjoining ground holding in Namibia it has
consolidated a significant area, highly prospective for the discovery of diamondiferous kimberlites.
Through its previous base metals exploration and resource development of its Kihabe zinc/lead/silver
project, which falls within this same area in Botswana, the Company has a well established base camp
and infra-structure from which it can conduct future diamond exploration programmes within reasonable
distances. This will significantly reduce on going future exploration costs while operating in this area
during this period requiring strict resource management.
HARDAP PROJECT - NAMIBIA
Location: Maltahohe district, Hardap, Namibia
Owner: MTB (Namibia) (Proprietary) Ltd. (various percentages)
The Company's wholly owned subsidiary, MTB (Namibia) (Proprietary) Ltd has been granted four
adjoining Exclusive Prospecting Licences (EPLs), covering a total area of 3,796 km² in the
Hardap region of Namibia. The EPLs 3435, 3473, 3474 and 3475 have been granted with the right to
explore for precious stones.
Several kimberlite pipes are known to exist within the area covered by these EPLs and the potential for
the discovery of further kimberlites is ranked as very high. Recent work conducted by the Geological
Survey of Namibia concluded that this area has potential to host diamantiferous kimberlites. The area
lies inland and west of Meob Bay and Diamond Area 2, in the drainage area of the Tsauchab River and
its tributaries. Although the present river disappears beneath the sands of the Namib Desert, its
palaeochannel reaches the coast near Meob Bay. The Company believes that kimberlites contained in
the EPL's have the potential to be the source for the diamond placer deposits that have been found
around Meob Bay.
MTB (Namibia) (Proprietary) Ltd will maintain a 60% interest in EPL3435, with 40% equity being held on
behalf of other Namibian corporations and an 80% equity in EPLs 3473, 3474 and 3475, with a 20%
equity being held on behalf of other Namibian corporations.
KIHABE BASE METALS PROJECT - BOTSWANA
Location: Ngamiland, Botswana and Tsumkwe, Namibia
Owner: Mount Burgess Mining NL 100%
Project Location
The Kihabe Base Metals Project is located on the border of Botswana and Namibia about 700km northwest of the capital, Gaborone, in Ngamiland. The Project is 350km by road from Maun and 50km from
Tsumkwe, Namibia.
Tenements
The Company has tenements covering 100% of the known prospective Proterozoic Belt of
metasedimentary rocks, with around one third of the prospective geology occurring in Botswana (PL
69/2003, area ~1,000km²) and two thirds in Namibia
The Kihabe Project was held in the early 1980’s by Billiton Botswana (Pty) Limited, which carried out
extensive soil geochemical reconnaissance and drilled three anomalous prospects, Kihabe , Nxuu
Prospect and the Gossan Prospect.
Regional Geology and Ore Genesis
The prospective geology of the Kihabe Base Metals Project is defined by a belt of Proterozoic
sedimentary rocks composed primarily of carbonate and siliclastic rocks. The Belt forms a trapezoidal
wedge of tightly to isoclinally folded metamorphosed sediments of the Damaran Supergroup, bounded
by granites and gneisses of the Quangwadum Complex and Kihabe Complex.
The target mineralisation is primarily stratiform to stratabound sedimentary exhalative (SEDEX)
sulphides occurring at a known stratigraphic level within the basin. The Company’s geological model is
that the Belt represents a re-closed rift basin with a fill of arkose, greywacke, quartzites and sabkhafacies stromatolitic dolomites.
Thirteen soil anomalies for lead, zinc and copper exist within the Company’s tenements in Botswana,
which include Kihabe, the Nxuu Prospect, Copper Anomaly and the Gossan Prospect. Extensive
reconnaissance soil sampling is underway in Namibia over similar terrain, with several anomalies
identified to date.
The Kihabe and Nxuu Zinc-Lead-Silver Resources
The Kihabe Resource is located along a contact between the dolomite footwall and a sequence of
rhythmically bedded sandstones, which have been folded and metamorphosed to, respectively,
dolomitic marble and chloritic quartzite. The local geology of the deposit is known to be a west-plunging
syncline.
Zinc, lead and silver mineralisation which is developed within the host quartzite within thick, coarse
grained beds, weakens upwards in the stratigraphy as the grain size reduces. Mineralisation forms a
series of overlapping stacked horizons controlled by the beds within the quartzite, over a strike length of
2.4 km.
The Nxuu resource is located approximately 5.5 km east south-east of Kihabe. Zinc and lead
mineralisation at Nxuu is developed within a shallow, flat lying sedimentary quartz wacke host rock,
situated in a synclinal structure or basin, bounded by barren dolomite.
The Company has published an initial JORC Resource at Kihabe and Nxuu. An initial programme of
13,000m of reverse circulation drilling and close to 6,000 metres of diamond core drilling has defined
27.4 million tonnes grading 2.32% zinc equivalency. 60% of the Resource conforms to an Indicated
Category and 40% to the Inferred Category.
Gossan Prospect
The Gossan anomaly is a two kilometre long, by half kilometre wide soil anomaly with +1,000ppm zinc
and +500ppm lead in soil, hosted within a valley bounded by dolomite, situated 15 km south of the
Kihabe resource.
The Company has identified an in-situ gossan outcrop with peak values in rock sampling of 21.95%
zinc, 7% Pb and 30 ounces per tonne of silver, which is a likely source for the extensive soil anomalism.
Development Progress
The Company is awaiting the results of a revised scoping study to determine the break-even metal
prices required for the Kihabe/Nxuu Project.
