Pancontinental Uranium Corporation (TSX VENTURE: PUC) ("Pancon")
and joint venture partner Crossland Uranium Mines Ltd. (ASX: CUX)
("Crossland") are pleased to update shareholders on the rare earth
alluvial sampling program from the Charley Creek Project, Northern
Territory, Australia.
Highlights
-- The accelerated two-part, Phase One Rare Earth Elements (REE) alluvial
sampling program is progressing on schedule; over 200 samples collected
to date.
-- Results of the Phase One program on the REE program are expected early
in 2011.
-- Assuming these results prove positive, an evaluation leading to Resource
definition is planned to commence immediately, with the aim of being
completed by late in 2011 on an initial alluvial volume.
Background
On November 1, 2010, Pancon and Crossland announced that
extensive alluvial deposits have been identified in their Charley
Creek Project, and that these deposits contained heavy minerals
with rare earth elements (REE).
These REE are present in phosphate minerals that should be
readily processible using available REE extraction technology.
The heavy mineral concentrate produced from the initial Charley
Creek tests weighed approximately 2kg and contained grades and
proportions of individual REE as indicated in the following table.
The concentrate was produced from panning approximately 400kg of
alluvium, followed by removal of the magnetic minerals from the
sample and a TBE heavy liquid separation.

This simple process route concentrated heavy minerals in the
alluvial material to grades that compare favourably with the
average grades of other rare earth developments currently being
contemplated. The concentrate also contains relatively high
proportions of all of those REE above europium on the Periodic
Table (Heavy REE), as the comparison with the published average
grades of REE in the Mountain Pass Deposit in California
illustrates:

NT production opportunities
Pancon and Crossland believe these results present opportunities
for production of a heavy mineral concentrate with high REE values
from the large volumes of alluvial sediment deposits that have
formed from erosion of the extensive source rocks of the Teapot
Granite within the Joint Venture's 4,000 square kilometre Charley
Creek Project in the NT.
These sediments are largely unconsolidated granite-derived
sands, and an alluvial heavy mineral deposit within these would
offer low mining costs, and simple, low cost upgrading using
gravity concentration processes to produce REE concentrates with
grades equivalent to, or in excess of, those that will be produced
as concentrates from the hard rock mining operation phase of most
other REE projects. All such concentrates need to be chemically
processed to separate the various rare earth elements.
Crossland believes that markets will be found for several
thousand tonnes per year of contained REE in a heavy mineral
concentrate product of this type.
On November 22, 2010, Pancon and Crossland announced that work
had commenced on a staged evaluation program with the aim of
rapidly characterising the distribution of the REE minerals, and
establishing the scope for heavy mineral accumulations in the
various alluvial settings identified in the Charley Creek
Project.
The current aggressive Phase One program involves:
-- Determining the heavy mineral types and REE content of streams draining
various parts of the Charley Creek Project.
-- Evaluating the tonnage and grade potential of one substantial area of
alluvium close to the site of the original sampling.
This first phase of work should be completed early in the first
quarter of 2011. The results will define the direction of further
work, which should lead to initial resource estimates by late in
2011.
Update on REE Samppling Program
Just over 200 stream sediment samples (206 samples) from the
approximate four (4) square kilometres of drainage areas have now
been collected. The full program will cover around 400 samples.
Processing of these has commenced at the Company's local
preparation facility. These samples represent the drainage from
about half of the 180km of mountain ranges within the joint venture
tenements at Charley Creek. Importantly, they cover many of the
stream outlets from these mountains which drain onto the extensive
alluvial flats to the north of the mountains.
These samples should determine what types of heavy minerals are
being fed from the Teapot Granite and surrounding metasediments in
the mountains onto these flats.
To date, 100 alluvial samples (of the 206 collected) have been
processed using a Wilfley Table, as indicated in the accompanying
Heavy Mineral Sample Flow-sheet. These will be passed through a
magnetic separator prior to heavy media separation and submission
for assay. A split of the heavy mineral concentrate, which will
contain the REE bearing minerals of interest, will be retained
until assays are received. If these are promising, the split will
be submitted for mineral characterisation and process
development.
Processing will continue on site throughout the Christmas break,
and will be placed on double shift if required to achieve required
throughput.
In addition to the stream sediment sampling, a program of hand
auger sampling of the alluvial flats around the Cockroach East
Uranium Prospect has commenced, to test the potential in one of the
many potentially REE-bearing alluvial flats throughout the project
area. Samples are being collected on 400m by 100m centres across
areas of alluvium to delineate zones where deeper alluvium exists.
Already, over 400 samples have been collected and these will be
processed once the alluvial samples are washed.
Areas with deeper alluvium will be tested with truck mounted
auger or vacuum drilling in Phase Two of the program. This is
expected to commence in February 2011 if results from Stage One
warrant this, and weather conditions permit access.

About Pancontinental Uranium Corporation
Pancontinental Uranium Corporation ("Pancon") is a
Canadian-based company focused on uranium discovery and
development. Through a 50:50 joint venture with Crossland Uranium
Mines Limited ("Crossland") of Australia, Pancon has established
one of the strongest management teams in the uranium industry. This
management and operating team has unparalleled experience from
exploration, through development to operations, and includes people
who were instrumental in the discovery of two of the largest
uranium deposits in the world. Pancon and Crossland hold an
impressive uranium exploration portfolio with projects in prolific,
mining friendly districts.
Active exploration is ongoing at three Australian projects which
include Chilling, Charley Creek, and Kalabity. The Chilling project
has the potential to host a mirror image of a portion of the
renowned Alligator Rivers Uranium Field containing the large
Jabiluka, Ranger and Koongarra deposits. Charley Creek has the
potential for large, lower-grade, Rossing-type, granite-hosted
uranium deposits and REE. The Kalabity project lies in a district
of historic uranium/radium mining that contains a variety of known
uranium deposit styles.
Pancon has earned a 50% interest in this significant uranium and
REE project portfolio through the joint venture with Crossland
through the expenditure of A$8 million. Pancon and Crossland are
also pursuing exploration beyond Australia through an international
subsidiary company, Crosscontinental Uranium Limited, and immediate
plans include formulating an exploration program in Burkina
Faso.
