The company has an active exploration program, now focused on the São Francisco craton of north-eastern Brazil, which hosts the Santa Rita resource.

The company's portfolio of other nickel and base metal projects in Brazil consists of Palestina, Serra Azul, São Francisco and Ponto Novo projects.

Mirabela's rights to explore, develop and mine the São Francisco and Ponto Novo are derived from exploration licences and applications for exploration licences that are 100% held and owned by Mirabela Brazil.

Palestina is approximately 25 kilometres from the Santa Rita Project and could provide additional sources of mill feed for the proposed mill. Geological mapping, rock and soil sampling and airborne and ground geophysics have been completed at the Palestina project area. A 1,700 metre (seven holes) diamond drilling program is currently underway and is considered to be a highly prospective target for Santa Rita type mineralisation.

Palestina also includes the Gongogi prospect, located approximately seven kilometres north of Palestina. Preliminary geological mapping suggests the presence of a layered intrusion at Gongogi, which might also be prospective for nickel sulphides. Further detail about Santa Rita is contained in the company's announcements.

São Francisco is an established nickel/copper exploration project believed to have the potential for large tonnage, disseminated mineralisation.

The São Francisco project area is located approximately 400 kilometres to the north of the Santa Rita Project site, approximately 15 kilometres from the neighbouring towns of Piranhas and Caninde de São Francisco, approximately 150 kilometres from the coast and approximately 20 kilometres from the Xingo hydroelectrical station.

The project comprises 50 kilometres of prospective strike length with known nickel sulphide occurrences from previous drilling. There are over five known nickel sulphide prospects.

Previous exploration of the São Francisco project was directed towards the discovery of high grade massive sulphides at depth. While this remains a target, the recent recognition of the economic potential of medium-tonnage, lower grade, disseminated, open-cut nickel sulphide projects such as Santa Rita, provides an opportunity to test surface mineralisation for open-cut potential.

A VTEM airborne geophysical survey did not provide clear drilling targets for such mineralisation, however the company intends to complete an IP ground geophysics survey of São Francisco. Re-interpretation of existing drill holes and geophysics suggest this surface mineralisation might be dipping towards the south-west, not north-east as previously assumed for drill hole planning.

The Ponto Novo nickel sulphide and laterite exploration project is located approximately 220 kilometres north-west of Salvador and about 30 kilometres from a railway terminal on the Centro Atlantico railway line to the mineral processing port of Aratu, near Salvador.

Further detail about exploration is contained in the company's announcements.
