Zambia is currently ranked as the world’s seventh largest copper
producer – generating 3.3 percent of the western world’s
and Bloomberg’s recent note on the future of mining
stated that the country could become the world’s fifth
largest copper producer by 2013.

Copper mine Zambia Vedanta leads the race for Zambian copper mine Vedanta, which owns Zambia's largest copper producer Konkola
Copper Mines (KCM), is pitted against China's Non-Ferrous
Copper Mine (NFC).
The other contenders include UK's Lion Finance and South
Africa's Shanduka Group, said the same person.
However, a Vedanta Resources spokesperson declined to comment.
An investment banker said the proposed acquisition of LCM
fits into Vedanta's plan to expand its copper business
Vedanta runs its Zambian copper operations through KCM,
in which it holds an 80% equity.
Vedanta has four mines, one each in Konkola and Nampundwe
and two in Nchanga, Zambia. Nama Copper/Cobalt Exploration Project, Zambia: Summary of Results of the 2011 Exploration Programme and Outline of the 2012 Exploration Programme
TORONTO, March 12, 2012 /CNW Telbec/ - Caledonia Mining Corporation
(the "Company") (TSX: CAL) (OTCQX: CALVF) (AIM: CMCL) is
pleased to announce the results summary of the 2011
exploration programme at its Nama Copper/Cobalt Project in
Zambia and outline the exploration programme for 2012.
The results from the 2011 drilling programme demonstrate a
new and very exciting aspect to the Nama Copper/Cobalt Project
A new mineralised copper zone has been identified
Estimated weighted average copper grade - 0.47%
Estimated weighted average thickness - 41 metres
Intersected depths of between 280 and 450 metres
A sufficiently large, near-surface resource up-dip from the
existing drill holes may provide the basis for a future open-
pit mining operation
The 2012 exploration programme will now commence as soon as
possible and will include the following three phases of
Phase 1: 2,400 metre drill programme to explore for potential
shallower up-dip continuation of the new mineralised zone to
Phase 2: 6,000 metre drill programme to explore for potential
deeper down-dip continuation of the new mineralised zone
Phase 3: A possible resource drilling programme to quantify the
shallower up-dip resources.
This phase cannot be finalised at this stage as the scope of
this programme is entirely dependent on the evaluation of the
Phase 1 programme results.
The costs of these drilling programmes will be fully funded
from current cash resources. Commenting on these exploration results, Stefan Hayden,
Caledonia's Chief Executive Officer and President said:
"The 2011 drilling programme at Nama identified a new and very
exciting aspect to Nama.
What we have found differs markedly in mineralisation style to
other properties in the region in that the zone we have
identified occurs in an atypical Copperbelt setting and
occurs in rocks overlying the Ore Shale. This zone of mineralisation occurs at relatively shallow depth
relative to the depth of the Ore Shale in the area and possibly
extends to surface.
A sufficiently large, near-surface resource depth may therefore
provide the basis for a future open-pit mining operation.
"The 2012 exploration programme will commence as soon as the rains and ground condition allow during the second quarter. The results should allow us to confirm and further refine our model of Nama's geology and copper resources potential. Caledonia has sufficient cash to complete the 2012 exploration programme and intends to manage its cash resources so that it can undertake further work at Nama without raising new equity."
Background to the Nama Project
Caledonia holds four, contiguous large scale mining licences covering approximately 800 square kilometres on the Zambian Copperbelt. The northern boundary of Caledonia's licenced area is the DRC border and the eastern boundary abuts the licence area that is held by a joint venture between Vale and African Rainbow Minerals where a new copper mine is currently under construction.
Prior to the 2011 programme, exploration activities had defined three main styles of mineralization in the Nama Licence area:
a) "A-type" cobalt oxide mineralisation;
b) "D-type' iron oxide bodies which are mostly enriched in Cobalt; and
c) Copper dominated ore shale hosted copper-cobalt mineralisation, commonly observed elsewhere in the Copperbelt and which is being exploited by neighbouring mines to the east and south of the Nama Licence Areas.
2011 Exploration Programme
The 2010 exploration programme identified two resource targets at Nama (being "Konkola East" and "Kafwira") which were characterised as belonging to the ore shale-hosted copper-cobalt style of mineralisation. The 2011 programme was focussed on Konkola East where a four-hole diamond drilling programme was carried out with the primary objective of confirming the existence of Ore Shale member of the Copperbelt stratigraphy. The results of this programme confirmed the existence of Ore Shale in all holes. The Ore Shale intersection in holes 1 & 2 was at depths and copper grades that do not merit further exploration at this stage. Evaluation of the drill core extracted from holes 3 and 4 identified a zone of mineralisation which occurs at considerably shallower depths than the Ore Shale and does not occupy a specific stratigraphic layer as would be expected. Assays of the mineralised zones identified in holes 3 and 4 were sufficiently encouraging to warrant a fifth hole being drilled in late 2011 and which also intersected the newly identified mineralised zone.
Preliminary Evaluation of the Results of the 2011 Drilling Programme
The new mineralised zone identified in holes 3, 4 and 5 is considered to be a contiguous zone. The assay results for the three intersections have a weighted average of 0.47% copper over a weighted average width of 41 metres at depths of between 280 and 450 metres. Holes 3 and 4 are approximately 1,650 metres apart representing a minimum strike length of the mineralisation. The interpreted structure of the mineralised zone suggests that the zone may extend to surface within the Nama Licence.
Although the copper grades of the newly identified zone are lower than existing mines in the region, the zone is relatively shallow and the ore mineralogy appears particularly suited to low-cost metallurgical processing.
2012 Exploration Programme
Caledonia's Board has reviewed the results of the 2011 exploration programme and the recommendations of management and has approved an exploration programme for Nama in 2012 which has the following objectives:
Phase 1: drilling of additional holes comprising approximately 2,400 metres with the objective of identifying a continuation of the newly discovered mineralized zone towards surface. This phase of the exploration programme is expected to start as soon as ground/weather conditions permit and results for this work are expected 4 to 5 months thereafter.
Phase 2: drilling of additional holes comprising approximately 6,000 metres with the objective of identifying the nature of a deeper continuation of the above mineralised zone. This work will take place after completion of Phase 1 and is expected to take approximately 8 to 10 months.
Phase 3: Provided the results of the Phase 1 programme are positive, a drilling programme focussed on delineating and evaluating resources compliant with NI43-101 will be presented to the Caledonia Board for approval prior to possible commencement. This Phase may commence during Phase 2 activities.
Substantial additional exploration work may be required in future years to arrive at a NI43-101 compliant resource statement.
Caledonia has sufficient cash resources to cover all of the exploration costs for 2012. Caledonia intends to manage its cash resources so that it retains the financial capacity to progress this project as far as possible without requiring third party involvement or equity funding.
