If you go to the power point presentation released by ORP on the 11th FEB got to the last pages it shows a map of ORP tenemants in MALAWI, • OROPAS - Chizani, central Malawi - 1283km2 (100%) is next door to GBE Kanyika deposit. (Brantley post map please)
Oropa sitting on some very attractive leases in Malawi.
Below is a detailed announcement by ORP on there area in MALAWI once again this news went unnoticed by the market just like im sure this post will lol:

URANIUM PORTFOLIO EXPANDS AS OROPA SECURES
THIRD MALAWI PROSPECTING LICENCE
KEY POINTS
• 1,283km2 Chizani Exclusive Prospecting Licence Granted.
• Significant recent activity from foreign uranium explorers with nearby projects
including Globe Uranium Limited and Paladin Energy Limited.
• Project area covers untested radiometric anomalies which are interpreted to offer
hydrothermal uranium exploration targets over elevated basement complex.
• Exploring for uranium and other specified minerals including copper, gold, silver,
niobium, rare earths, tantalum, scheelite and wolframite
• Substantially expands Oropa’s existing uranium portfolio, positioning the company
as a significant uranium explorer.
Oropa Limited (ASX: ORP – “Oropa”) is pleased to announce that it has secured a significant
addition to its uranium exploration portfolio in central Africa after being granted a third Exclusive
Prospecting Licence (EPL) covering a total area of 1,283 square kilometres in the Chizani area
of central Malawi, located near Globe Uranium Limited’s Kanyika Project, (“Globe’s”).
The grant of the EPL, to Oropa’s 100%-owned subsidiary, Oropa Exploration PL, was announced
by the Minister of Energy, Mines and Natural Resources of the Republic of Malawi, giving Oropa
the right to explore for uranium and other specified minerals including copper, gold, silver, niobium,
rare earths, tantalum, scheelite and wolframite within the Chizani Project Area.
The addition of Chizani to the Company’s existing portfolio of 100%-owned exploration projects
(Mzimba Northwest and Chitunde) increases its total ground position to over 3,600 square kilometres.
In November last year, Oropa entered into Memorandum of Understandings to acquire a 90% interest
in two contiguous EPLs, Ngana and Ngana East, located just 20km north of Paladin Energy Ltd’s
(“Paladin’s”) Kayelekera Uranium deposit in northern Malawi. The Ngana EPLs represent a significant
strategic addition to its uranium exploration portfolio.
The proximity of the Chizani EPL to the nearby Kanyika Project, owned by Globe, provides Oropa with
a nearby uranium-niobium-tantalum deposit model to apply to exploration search parameters within
the Chizani area. Globe currently has intensive resource definition drilling programs underway at
Kanyika, with assay results awaited.
Collectively, Oropa’s tenement portfolio in Malawi offers uranium exploration potential for a number of
uranium deposit types in specific geological environments including: roll-front, unconformity and
hydrothermal styles of uranium mineralisation.
EPL0223/07 – Chizani Project Area
Chizani is situated in central Malawi nearby Globe’s multi-commodity Kanyika property, where RC
and core drilling of uranium-niobium-tantalum-zircon mineralisation hosted by alkalic granitoid and
pegmatitic zones is presently taking place ahead of resource estimation and metallurgical studies.
Recently granted tenements in the district are also held by CC Mining SA.
Chizani covers 1283 square kilometres of structurally complex Malawi Basement Complex
composed of metamorphic rocks of both igneous and sedimentary origin belonging to the
Mozambique Orogenic Belt of Precambrian to Lower Palaeozoic age. A significant structural
feature of the Chizani Project area is coverage of over 30 kilometres strike length of the Chimaliro
Fault zone. This fault forms the southern boundary of the Champhira Dome and extends into
neighbouring Zambia.
Physiographically, the project area may be divided into several units. The most prominent of these
include the Kasungu Plain that forms an area of low relief in the western sector and to the
northeast abuts the Nkhotakota Scarp Zone where relief exceeds 300 metres in a region of deep
dissection. Over northern parts of the project the rugged Viphya Mountains dominate with areas of
high relief.
EPLO223/07 covers highly structured metamorphic rocks forming basement represented by
gneisses, granulites, schists, quartzites, and mylonites. Granitoid and biotite gneisses are common
within the project area. Intrusive rock types include pegmatites and metamorphosed equivalents
of mafic and ultramafic rocks. Regionally, quartz syenites, lamprophyres and calc-silicate gneisses
interbanded with marble have been identified (see Fig. 1.)
The basement complex is believed to have suffered two major structural and metamorphic events
ending with the emplacement of the Champhira Dome as a tectonic wedge. Major post basement
complex structuring comprises uplift and rift faulting. The majority of the faulting is on north and
northeast trends but subsidiary fractures occur on east northeast trends.
Known previous ground exploration over Chizani appears to have been limited to a regional
geochemical stream sediment survey conducted as part of a development programme for Malawi
conducted intermittently during the 1960s and early 1970s.
Published information reports a zinc geochemical anomaly associated with the granitoid over the
northern sector of the project area, together with anomalous copper, nickel and chromium values
over the Champira Dome area – a portion of which falls within Chizani north of the Chimalira
Fault. Unfortunately, the historical geochemical surveys excluded analysis for gold and uranium.
Figure 1 – Chizani Geological Setting
Further information on the general prospectivity of Chizani is available from the UNDP-sponsored
airborne radiometric survey of the area in 1984/85. A significant number of radiometric anomalies
are evident within the property from this work which warrant further investigation and ranking for
ground follow-up (see Fig. 2.).

The proximity of Chizani to the nearby Kanyika Project provides Oropa with a nearby uraniumniobium-
tantalum deposit model to apply to exploration search parameters within the Chizani area.
Proposed Exploration
Oropa plans to systematically explore Chizani for uranium and other minerals, commencing with a
reassessment of the identified radiometric anomalies which will be ranked in order of priority for
their prospectivity for uranium occurrences and subsequent ground spectrometer surveys.
This work will be augmented by geological interpretations of the search areas using satellite
imagery. Priority targets will then be assessed using a combination of soil, rock and stream
sediment surveys in order to outline areas for more intensive exploration. These geochemical
studies will be augmented by geological mapping and ground geophysical surveys.
Over areas warranting detailed assessment, systematic trenching of anomalous areas will be
undertaken followed by reconnaissance drilling to establish the tenor of mineralisation present both
along strike and at depth. It is envisaged that highest priority areas of mineralisation with
demonstrated economic potential will be tested first by reconnaissance and in-fill drilling in order to
provide sufficient information for a preliminary assessment of resource potential present prior to
making a more detailed assessment.
Currently, Oropa is reviewing existing data and plans to acquire satellite imagery covering areas of
interest with a view to establishing a GIS database as part of the preparation for ground
investigations.
Oropa has established a base in Lilongwe and field operations are planned to recommence after
the end of the wet season, which normally ends in late March.
Uranium Exploration in Malawi
Uranium exploration in Malawi presently reflects the high level of interest in the development of the
Kayelekera Uranium Project in the north of the country by Paladin. The Kayelekera Uranium
Project, where roll-front style mineralisation is hosted by Karroo sandstone and mudstone
sediments, is scheduled to be commissioned in late 2008 with a planned annual production of 3.3
Mlbs of U3O8 over a mine life of 7 years based on reported Proven and Probable Ore Reserves of
10.46 Mt at 0.108% U3O8.
Uranium in Malawi is however not limited to Karroo-hosted deposits.
Globe is currently exploring multi-commodity uranium-niobium-tantalum mineralisation associated
with 5 northerly trending stacked mineralised zones within an alkalic granitoid at the Kanyika
Project in central Malawi. Results from recent drilling programmes indicate that the known
mineralisation at Kanyika extends over a strike length of up to 3.4 kilometres with known depth
extensions from surface of up to 150 metres. Globe has announced that a JORC compliant
resource estimate for a portion of the Kanyika Project is currently being undertaken which is
scheduled to be completed in the first quarter of 2008.
Some of the better reported RC drilling intercepts from three of the five mineralised zones at the
Kanyika deposit include: 42m @ 79ppm U3O8, 2,922ppm Nb2O5 and 115ppm Ta2O5 from surface,
71m @ 63ppm U3O8, 2,673ppm Nb2O5 and 125ppm Ta2O5 from 46m and 27m @106ppm U3O8,
2,829ppm Nb2O5 and 166ppm Ta2O5 from 51m.
Other known uranium mineralisation in Malawi is based on historical records and includes uranium
and niobium mineralisation hosted by nepheline syenite complex intrusions. In the far northwest of
the country at the Ilomba Hill locality, surface trenching in the 1950s investigated a radioactive
zone where rock samples returned analyses up to 2.15% U3O8 and 7.50% Nb2O5 associated with
uranian pyrochlore.
The starting point for area selection for uranium properties in Malawi is the country-wide
radiometric surveys conducted in 1984/85 by Hunting Geology and Geophysics Limited based at
the time in the United Kingdom. The uranium anomalies and geological settings identified by those
surveys are the basis for Oropa’s selection of the Chizani area.
Yours faithfully,
OROPA LIMITED
