SYDNEY, Australia, Dec. 31 /PRNewswire-FirstCall/ -- Volcan
Holdings Inc., (OTC:VOHO) (BULLETIN BOARD: VOHO) through its
wholly-owned subsidiary Volcan Australia Corporation Pty Ltd, has
secured tenement access to over 4,000km2 of bauxite-prospective
ground in New South Wales, Australia. The tenements are located in
the northern and southern parts of the state and encompass two
large volcanic provinces known to host widespread deposits of
bauxite. The bauxite deposits in these provinces are very different
to the traditional deposits mined in many parts of the world, and
appear to have been formed by a unique combination of volcanic and
weathering processes to produce gibbsite-rich rocks with high
available aluminium (up to 60%) and low reactive silica (as low as
1.5%), when concentrated near ancient basaltic volcanic vents.
Project highlights to-date include:- 1. Bauxite exploration
tenements secured and offered for grant by the New South Wales
Department of Primary Industries includes, ELA 3506 in the Central
Volcanic Province near Inverell covering approximately 1,000km2,
and ELA 3595 in the Monaro Volcanic Province near Cooma covering
more than 3,500km2. Total prospective area >4,500km2. 2. Thick
deposits of bauxitic rocks (greater than 20m) discovered in at
least 3 large volcanic domes within Exploration License Application
3506, with the domes encompassing a total aggregate area of more
than 70km2, and the potential to host world class deposits in the
hundreds of millions of tons just within these 3 dome structures
covering only about 2% of the prospective area, with potential for
identification of billions of tons of resource within our various
project areas. Such world class sized deposits, should they be of
sufficient economic grade, as we believe our projects host based on
our results to date as detailed below, typically can generate
annual revenues in the billions of dollars. Our goal is to mine
sufficient high grade bauxite to profitably produce through
refining and smelting a minimum of 5 million tons of aluminium per
annum. At current aluminium prices of $1,500 per ton, 5 million
tons of aluminium per annum would generate annual revenues of $7.5
billion. 3. Outcrop sampling across one of the largest target
domes, has confirmed the existence of significant deposits of
commercial grade bauxite, with available Al and reactive Si
percentages ranging up to 59% Al, and as low as 1.2% Si. Current
grade modelling indicates averages of Al = 38% & Si = 3% across
the area sampled to-date. 4. Hydrothermally altered basaltic
volcaniclastic rocks hosting rich concentrations of almost pure
gibbsite have also been found in suspected near-vent locations
within parts of these domes yielding Al values as high as 59% and
Si values as low as 1.2%. 5. The samples taken to date have shown
in the lab to be suitable for low-temperature refining using the
Bayer Process. This is a serious advantage for the economics of
bauxite refining, as low-temperature refining uses significantly
less energy than the high temperature refining necessary in many
other bauxite projects, which is one of the main ongoing operating
costs in those projects rendering many uneconomic in the current
climate. 6. Numerous volcanic structures hosting bauxite deposits
have also been identified within ELA 3595, while deep drilling and
stratigraphic mapping has determined that approximately 9% of the
entire vertical volcanic pile in the Monaro Volcanic Province is
bauxitic. 7. Bauxite deposits in both tenement areas are close to
potentially available sources of power and water that may support
refinery development for local processing of economic deposits. For
