Back in the game - WPG returns to the iron ore industry at Giffen Well
WPG Resources Ltd (ASX:WPG) withdrew from the iron ore sector
when it sold its iron ore assets to OneSteel in October 2011
for approximately $320 million.
The Company is pleased to advise that it has now re-entered
the iron ore business in South Australia with the signing of
binding Heads of Agreement with Brisbane based Maosen
Australia Pty Ltd covering EL 3945 at Giffen Well.
Giffen Well was originally part of the South Australian Steel
and Energy Project (SASE) but had been relinquished by the
time WPG acquired the Peculiar Knob and Hawks Nest tenements
from SASE in 2006. Its location is shown below.
ASX Announcement - 24 January 2012
Significantly Giffen Well lies within the Green Zone of the
Woomera Prohibited Area
(WPA) as shown below. It is not in the more sensitive Red or
Amber Zones.
Giffen Well is just 25 kilometres from the Carnes siding on
the Central Australian railway line. There is direct rail
access to WPG's port facilities at Port Pirie, a distance by
rail of 550 kilometres.
Ground geophysical and drilling programs carried out as part
of the SASE project outlined a significant deposit of
magnetite BIF at Giffen Well that is part of the Wilgena Hill
Formation of Paleoproterozoic age and a continuation of the
Hawks Nest BIF stratigraphy. The Giffen Well area lies
adjacent to the large north-east trending Bulgunnia Shear
Zone along with a number of other significant mineral
deposits and prospects including Prominent Hill and Hawks
Nest.
The previous drilling at Giffen Well focussed on the
magnetite BIF. However the BIF is in places in contact with
granite of the Hiltaba Suite. This is a geological setting
that is analogous to that at Peculiar Knob where high grade
(>60%Fe) massive hematite is located adjacent to Hiltaba
aplite and granite in the footwall. These contact zones at
Giffen Well are considered to be prime conceptual targets
that
have good potential for the discovery of DSO haematite
orebodies such as that at
Peculiar Knob and Buzzard at Hawks Nest.
Previous drilling at Giffen Well consists of 58 drill holes
of which 32 were vertical holes drilled as part of two
regional drilling programs. The other 26 holes comprised
25 inclined RC percussion holes and 1 diamond drill hole that
were sited on six east-west traverses and designed to test
ground magnetic and gravity anomalies. Traverse spacing
ranged from 300 metres to 800 metres and the hole spacing was
nominally 100 metres. Hole depths ranged from 52 metres to
114.2 metres.
The location of the existing drill holes is shown in the
drawing below.

ASX Announcement - 24 January 2012
Note that the Fe grades at Giffen Well are high and are
similar to those at Hawks Nest. The grades are much higher
than many of the magnetite deposits elsewhere in South
Australia, and in particular those for the Braemar iron
formation in the Peterborough - Broken Hill area, and the
Eyre Peninsula.
A typical drilling section at Giffen Well is shown in the
drawing below. Note that the BIF subcrops on this section. It
forms a strike ridge on other sections, where BIF scree is
well developed at the surface.
The combination of high grades and shallow depth suggest low
unit mining costs per Fe unit mined.
The spacing of the 26 deeper holes drilled previously on the
main BIF strike ridge is too wide to enable a JORC compliant
resource to be estimated at this stage of project's
development. However WPG has outlined an exploration target
of BIF mineralisation in the range 390 - 500 million tonnes
at a grade of between 33% and
38% Fe. This exploration target is based on the drill hole
and other data currently available and is conceptual in
nature. There has been insufficient exploration to define a
mineral resource for this exploration target, and it is
uncertain if further exploration will result in the
determination of a mineral resource in this area.
Preliminary beneficiation tests carried out as part of the
SASE project suggest that a high grade iron concentrate of
about 69% Fe with very low levels of alumina and phosphorous
may be readily produced from the Giffen Well magnetite
BIF.
WPG plans to commence a substantial program of systematic
resource development drilling that will provide the basis for
a preliminary feasibility study. If this is positive as
expected, a joint venture will be formed with Maosen to
develop the project.
ASX Announcement - 24 January 2012
The key commercial terms of WPG's agreement with Maosen are as follows:
• WPG will hold its interest in Giffen Well through its subsidiary Giffen Iron Pty
Ltd (GIPL);
• GIPL will pay an access fee of $200,000 (plus GST) and WPG will allot
$330,000 worth of WPG shares to the vendor when the last of the conditions (renewal of tenement, Defence and landowner access, Native Title (Exploration) agreement) are satisfied;
• The WPG shares will be issued at the higher of 10 cents per share or a 20%
premium to the 30 day VWAP on the date of issue;
• GIPL will pay a modest annual retainer to the vendor in recognition of services provided;
• GIPL will carry out a drilling program aimed at outlining a 500 million tonne resource, and will complete a PFS that will cost an estimated total of $1 million;
• GIPL can earn up to an 82% joint venture interest in the project by the payment of $5 million to the vendor and funding a bankable feasibility study;
• If a decision to develop a mine is taken GIPL will pay a further $10 million to the vendor, at which time Maosen has the right to decide whether to retain its equity interest in the project or exchange it for a royalty of $0.70 per tonne of ore mined; and
• The non iron ore rights will remain with Maosen.
WPG regards Giffen Well as one of the best iron ore project
opportunities available in Australia. For a range of reasons,
very little work has been done on it in the last 4 years -
the iron ore boom has largely passed it by. WPG is looking
forward to advancing the project as aggressively as this can
reasonably be achieved over the next few months and
years.
The agreement with Maosen was signed yesterday, Chinese New
Year. The omens are good for new business ventures in the
Year of the Water Dragon.
