INVESTOR PRESENTATION, Mining 2011, Brisbane,
Queensland, including exploration at East Frome Pb-Zn-Ag-Cu-Au Project,
Located 30km NW of Broken Hill, NSW.
Located in North West Queensland, Cannington (BHP
Billiton 100 per cent) is a fly-in fly-out mining and processing operation
that has grown to become the world’s largest and lowest cost producer of
silver and lead. The operation consists of an underground mine and
metallurgical processing facility.
CBH is a resource company which involves in underground
mining (zinc, lead, silver) in Cobar, NSW and CBH also has base metal
development projects in Western Australia and Broken Hill, a concentrate
ship loading facility at Newcastle and major exploration positions in both
Western Australia and NSW.
Initially incorporated in Tasmania, Australia in 1999
and trading as Zeehan Zinc Limited, Creat Resources Holdings Limited is a
mining, exploration and development company seeking to mine and process
certain zinc, lead and silver deposits in Western Tasmania, Australia.
The Magellan Mine (“Magellan” or the “Mine”),
in Western Australia, is the world’s largest lead carbonate mine. On April
7, 2011, Ivernia announced that it had placed the Magellan Mine on care and
maintenance. Three lead deposits have been discovered on Magellan Hill,
namely the Magellan, Cano and Pinzon deposits. Initial discovery of the
Magellan deposit was in 1993, followed by Cano in 2001 and Pinzon in 2004.
Two outlying deposits, Drake and Pizarro were discovered approximately 20 km
to the south of Magellan Hill.
In June 2010 Ivernia entered into an earn-in agreement
on the Prairie Downs Base Metal Project (Prairie Downs" or the
"Project") in Western Australia. This is the first joint venture
undertaken as part of the Company's corporate growth strategy to acquire and
explore a portfolio of base metal projects. Under the terms of the earn-in
agreement, a wholly owned subsidiary of Ivernia may earn up to an 80%
interest in Prairie Downs, as outlined below. The Project is located in an
area with good infrastructure, in the Pilbara, a prolific mining region in
Western Australia. The majority of past exploration at Prairie Downs was
focused on a limited area, in which previous operators outlined a small JORC-compliant
resource, the Prairie Deposit (the PD"). Potential exists to enlarge
the PD and for the discovery of additional zones of lead-zinc+/-silver
mineralization along the 20 kilometer long Prairie Downs Fault System, a
regional-scale structure associated with base metal mineralization on the
Project.
The Company’s wholly owned Mt Zephyr Project is
located 70km north-east of Leonora. The project is targeting Volcanogenic
Massive Sulphide (VMS) deposits similar to those found at the Teutonic Bore
copper-zinc-lead mine located 60km west. RC drilling was completed during
the Quarter with 15 holes for 2,176m.Seven diamond holes completed for
3,227, sulphides intersected in all holes, with most significant
intersection of 9m @ 0.67% zinc and 0.16% lead.
LEICHHARDT COPPER-GOLD-REE PROJECT, NORTHWEST
QUEENSLAND The Company commenced tenement pegging in the Mt Isa Inlier of
Northwest Queensland, targeting copper-gold-rare earth mineralization in
Iron Ore Copper Gold (IOCG) settings. In terms of exploration potential, Mt
Isa Inlier is a very well mineralised Cu-Au, Pb-Zn-Ag, U-REE and Mo-Re
province, with one or two world class deposits discovered virtually each
decade (Ernest Henry 1991 discovery, 122Mt at 1.14% Cu and 0.55g/t Au; Mt
Elliott 2009 discovery, 570Mt at 0.44% Cu and 0.26g/t Au, both IOCG
deposits).

Jabiru Metals Limited (Jabiru) is an Australian
resources company whose key products are zinc and copper sold to refineries
in the form of zinc concentrate and copper concentrate. Jabiru's copper
concentrate also contains significant silver credits and a small amount of
gold. The Jaguar Exploration Project encompasses 3 high grade VMS deposits,
Teutonic Bore, Jaguar and Bentley, centred on the Jaguar mine approximately
300km north of Kalgoorlie and equidistance between Leonora 65km by road to
the south and Leinster to the north. Production began from Jaguar in 2007
and in late 2008 Jabiru Metals discovered the Bentley deposit 4km to the
south. The Bentley high grade resource remains open at depth and is
currently being developed with production planned for 2011.
The Stockman Project is located in the Victorian Alps
region 470km by road north-east of Melbourne and 60km by road north east of
Omeo. The project contains two copper-zinc-lead-silver-gold rich VMS
deposits, Wilga and Currawong. Wilga was discovered by a WMC /BP joint
venture in 1978 and Currawong in 1979. Denehurst mined the copper rich core
of Wilga deposit from 1992 to 1996. In 2006 following rehabilitation of the
plant site and tailings dam by the Victorian Department of Primary
Industries the project was put out for public tender as part of an
exploration incentive program. Jabiru was awarded the project in March 2007.
Kagara Zinc Ltd is a mining company in Western
Australia which mines zinc, lead oxide, copper, silver and gold. Kagara has
completed a pre-feasibility study on the world-class, potentially Tier One
Admiral Bay zinc-lead-silver-barite project in Western Australia.
The Company is currently seeking equity or joint venture partners to
underpin an externally funded Bankable Feasibility Study.
Kagara Ltd has four operational hubs at Mungana, Mt
Garnet, Balcooma and Thalanga in North Queensland. Mt Garnet, which was the
Company’s first operation in the region, is its administrative and
processing centre with two operating treatment facilities – a polymetallic
plant that treats high-grade ore sourced from the Mungana underground mine
and nearby Mt Garnet underground mine, and a copper circuit that treats ore
sourced predominantly from the Balcooma underground mine. The Mungana
operations include a partially completed polymetallic concentrator which, if
completed, has the potential to underpin a substantial increase in Kagara
Ltd’s zinc production, which would be driven by the development of new
deposits in the region such as King Vol and The Thalanga operations include
a treatment facility capable of treating both polymetallic and copper ore
which currently processes ore from the high-grade Vomacka open pit. These
mines supply ore to Kagara Ltd’s copper and polymetallic plants at Mt
Garnet, as well as the polymetallic treatment facility at Thalanga. In the
FY 2011, Kagara Ltd produced: • 22,530t copper, targeting an increase
of more than 30,000tpa by FY 2015. • 40,125t zinc-lead, targeting an
increase to 71,000tpa by FY 2014.
Kingsgate entered into an agreement in August 2011 to
purchase the Bowdens silver project in Lue, New South Wales, from a
wholly-owned subsidiary of Silver Standard Resources Inc., subject to the
satisfaction of certain conditions precedent. Bowdens, located some 240 km
west of Sydney, is an epithermal silver deposit with a resource of
approximately 100 Moz silver reported in line with JORC guidelines. Bowdens
has the potential to be developed as an open pit operation with the capacity
to sustain a 3 - 4 Mtpa ore processing rate over a minimum 10 year mine
life. Silver mineralisation is associated with lead [0.3%] and zinc
sulphides [0.4%].

The Angas Zinc Mine is 100% owned and operated by
Terramin.
Production at Angas commenced in July 2008. The initial Probable Reserves of
2.15 million tonnes at 10.5% Pb+Zn were
sufficient for a seven year operation. Drilling results from the near mine
area show strong indications of further shoots that would extend mine life.
The mine is located in an historical mining belt where the Company holds
over 1000km2 of tenements with encouraging exploration results, offering
further potential for deposits that could be processed at Angas or developed
into new mines.
Terramin, via its wholly-owned subsidiary, Menninnie
Metals Pty Ltd, owns and operates four contiguous exploration tenements in
the southern Gawler Ranges, South Australia, collectively known as the
Menninnie Zinc Project. The tenements are: Menninnie Dam EL3640; the Nonning
JV EL3535; Kolendo EL4285; and Taringa EL4669.
