OZ Minerals possesses extensive exploration experience both in Australia and at international sites. Growth through exploration is a central part of our strategy to add value to the company.
OZ Minerals has multiple exploration earn in agreements in place with highly regarded explorers. These provide OZ Minerals with exploration expertise in specific geologies or locations. Our partners in turn access capital to undertake drilling programs. OZ Minerals typically works with its partners to oversee projects while they manage on the ground activities. OZ Minerals’ growth strategy involves building a pipeline of opportunities and rigorously progressing these. In line with our capital discipline strategy, if at any time it is determined that a project does not have the potential to generate substantial value, OZ Minerals will cease expenditure and withdraw from the arrangement.
For the latest information on exploration and relevant disclosures under JORC 2012, please refer to our quarterly reports and ASX releases. Below is a brief outline of our current exploration projects.
Multi-site exploration alliance
In January 2019, OZ Minerals entered into an exploration alliance with Red Metal Limited, which will significantly increase its exploration footprint in Australia.
The Alliance gives OZ Minerals a two-year option to fund a series of mutually agreed, proof-of-concept work programs on six of Red Metal’s early-stage projects, which includes:
- Yarrie for copper-gold and copper-cobalt in WA
- Nullarbor for copper-gold and copper-nickel in WA
- Gulf for copper-gold in QLD
- Three Ways for zinc-lead-silver in QLD
- Lawn Hill for zinc-lead-silver in QLD, and
- Mount Skipper for zinc-lead-silver-copper in QLD

In December 2018, OZ Minerals entered into an earn-in agreement with private Peruvian company Inversiones Mineras La Chalina S.A.C. to explore for iron oxide copper-gold (IOCG) deposits in the Arequipa district of southern coastal Peru.
Historical exploration on the licences has included soil sampling, geological mapping, limited geophysics and drilling of nine holes. The drilling focussed on a small (150 x 150 metre) area near historical workings, and the majority of drill holes intersected copper mineralisation. At the Esmeralda target zone, surface copper oxide mineralisation has been traced over a strike length of 400 metres. At the Casper target a 400 x 300 metre copper-in-soil anomaly has been outlined by previous explorers. Neither target has been drill-tested.
The initial work program is planned to include geological mapping, rock chip and soil sampling, ground geophysics and an airborne magnetic survey.
OZ Minerals has committed to spending US$500,000 on exploration in the first 12 months, after which it can elect to proceed with the project. If it elects to progress, OZ Minerals can earn 100% of the project by spending US$11,525,000 over five years.
We have the second largest portfolio of exploration projects in Brazil, which spans over 1,800 square kilometres.
Pantera is high-grade copper-gold exploration project covering approximately 100km2 in the Carajás in Northeastern Brazil.
An initial drilling program is currently being assessed with the aim of identifying a maiden JORC Mineral Resource.

In June 2018, OZ Minerals entered into an agreement with private explorer Mineral Prospektering i Sverige (MPS) to explore for Iron Oxide Copper-Gold (IOCG) mineralisation in the Norrbotten district of northern Sweden.
Historic exploration on the leases by previous explorers intersected a copper and zinc skarn system on the Huornaisenvuoma prospect in the southwest of the license and they also defined two small magnetite-hosted iron occurrences, Kevus and Teltaja. Subsequent gravity and electromagnetic (EM) surveying by the Swedish Geologic Survey (SGU) revealed a continuous, 3.8km long, untested gravity anomaly between Kevus and Teltaja with a coincident EM response.
OZ Minerals can earn 75% of the project by spending US$10m over 66 months and has the right to purchase a further 25% equity

In December 2017, OZ Minerals entered into an exploration earn-in agreement with Red Metal Limited (Red Metal) to explore for Iron Oxide Copper Gold (IOCG) approximately 50km south of the Carrapateena project. Red Metal is an ASX-listed Australian mineral explorer with exploration experience in some of Australia’s most productive mineral provinces.
The prospects at Punt Hill have geophysical similarities to the deposits at Carrapateena with untested targets having coincident gravity and magnetic anomalies. Previous work on the project has uncovered many examples of IOCG mineralisation along large structures.
Punt Hill’s proximity to Carrapateena opens up potential opportunities to leverage Carrapateena mine infrastructure and it further consolidates OZ Minerals presence in this highly prospective region.

In April 2017, OZ Minerals entered into an agreement with Acapulco Gold Corp targeting three newly identified base metal prospects in Oaxaca, South Mexico.
The sites being targeted have the potential for volcanic-hosted massive sulphide (VHMS) deposits. VHMS deposits are significant contributors to the global production of copper, zinc, lead and silver.
Acapulco Gold is a private exploration company based in Canada with significant experience and a discovery track record in Mexico.
(100% OZ Minerals, Mithril earning in)
In July 2016, OZ Minerals entered into an agreement with Mithril Resources to explore seven exploration licences in South Australia’s far western Coompana Province. Mithril is an experienced nickel and copper exploration company based in South Australia.
The Coompana area has been the subject of a significant amount of airborne and ground geophysics conducted by the South Australian Department of State Development in collaboration with PACE Copper. The areas are essentially unexplored and provide OZ Minerals with an opportunity to make exciting discoveries.

In December 2015, OZ Minerals and Minotaur Exploration entered into a binding Heads of Agreement for the Eloise Project, located near Cloncurry, Queensland.
The Cloncurry Mineral District contains strong mineral endowment in a variety of commodities, including Cu-Au (Ernest Henry, Eloise, Osborne and Mount Elliot/Swan deposits) and Zn-Pb-Ag (Cannington, Pegmont). The geology of the tenements indicates excellent prospectivity for high-grade Eloise-style Cu-Au and Cannington-style Pb-Zn-Ag deposits.
