South32 to Acquire Arizona Mining in Agreed All Cash Offer

VANCOUVER, British Columbia and PERTH, Australia, June 17, 2018 (GLOBE NEWSWIRE) -- South32 Limited (ASX:S32) (JSE:S32) (LSE:S32) (ADR:SOUHY) (South32) and Arizona Mining Inc. (TSX:AZ) (Arizona Mining) announced today that they have entered into an agreement for South32 to acquire the remaining 83 per cent of issued and outstanding shares of Arizona Mining via a plan of arrangement, representing a fully funded, all cash offer of US$1.3 billion¹ (C$1.8 billion). The offer price of C$6.20 per share represents a 50 per cent premium to the closing price on 15 June and implies a total equity value for Arizona Mining of US$1.6 billion¹ (C$2.1 billion). Directors and officers of Arizona Mining, who own 34 per cent of the common shares on issue, have entered into voting support agreements and the directors of Arizona Mining entitled to vote, have unanimously recommended to their shareholders that they vote in favour of the transaction.

Arizona Mining is the owner of the Hermosa Project, containing the high grade base metals Taylor deposit, the Central zinc, manganese and silver oxide resource and an extensive, highly prospective land package with potential for discovery of polymetallic and copper mineralisation. The Taylor deposit is a greenfield development project that has a reported resource of 101 million short tons^2,[3] (Measured and Indicated Mineral Resources) at 10.4% zinc equivalent grade and is open at depth and laterally. The project is located close to key infrastructure in an attractive mining jurisdiction. A Preliminary Economic Assessment completed by Arizona Mining in January 2018 indicated that this low cost, long life project has the potential to deliver a very high Internal Rate of Return on investment².

South32 Chief Executive Officer, Graham Kerr said: “Our all cash offer for Arizona Mining will allow us to optimise the design and development of one of the most exciting base metal projects in the industry. We have been a major shareholder in Arizona Mining since May 2017 and an active participant in the Hermosa Project with representation on the operations committee and a nominee on the board of directors. Our deep understanding of this high grade resource and surrounding tenement package, and extensive experience at Cannington, makes us the natural owner of this project and ensures we are well positioned to bring it to development, delivering significant value to our shareholders.”

Arizona Mining founder and Executive Chairman, Richard Warke said: “South32’s all cash offer of C$6.20 per share represents a premium reflective of the truly world class nature of the Hermosa Project and allows shareholders to realise immediate value. In addition, the transaction is not contingent on financing, which significantly reduces transaction risk.

Our board of directors and a special committee of three independent members from the board of directors evaluated this offer and determined that it represented the best outcome for all shareholders. Importantly, South32 knows the asset well and understands the significance of the strong relationships that we have built in Arizona with all of our stakeholders.  I wish South32 all the best in developing Hermosa and the Taylor deposit.”

Forward-looking statements

This release may contain forward-looking statements, including statements about currency exchange rates, commodity prices, production forecasts, plans, development decisions, exploration and capital expenditure.  These forward-looking statements reflect expectations at the date of this release; however, they are not guarantees or predictions of future performance.  They involve known and unknown risks, uncertainties and other factors, many of which are beyond our control, and which may cause actual results to differ materially from those expressed in the statements contained in this release.  Readers are cautioned not to put undue reliance on
forward-looking statements.  Except as required by applicable laws or regulations, neither South32 Limited nor Arizona Mining Inc. undertakes to publicly update or review any forward-looking statements, whether as a result of new information or future events. 

Mineral Resources – clarifying statements

The estimates of Mineral Resources for the Hermosa Project (Arizona Mining) are foreign estimates under the ASX Listing Rules reported in accordance with the National Instrument 43-101 (NI 43-101) and filed on SEDAR (www.sedar.com) on 16 January 2018.

In accordance with National Instrument 43-101, Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of mineral resources will be converted to Mineral Reserves. Inferred Mineral Resources are based on limited drilling which suggests the greatest uncertainty for a resource estimate and that geological continuity is only implied. Additional drilling will be required to verify geological and mineralisation continuity and there is no certainty that all of the Inferred Resources will be converted to Measured and Indicated Resources. Quantity and grades are estimates and are rounded to reflect the fact that the resource estimate is an approximation.

The categories of Mineral Resource classification used are in accordance with NI 43-101. NI 43-101 is a ‘qualifying foreign estimate’ (Chapter 19, ASX Listing Rules) and has similar categories of resource classification as the JORC Code (Appendix 5A, ASX Listing Rules).        

South32 considers these estimates to be both relevant and material to South32 given that this project has the potential to be a material project to South32.

Reliability of estimate: South32 has experience of managing similar operations to the Hermosa Project. South32’s key technical and operational personnel conducted site visits as part of the due diligence process. Arizona Mining provided information used to estimate Mineral Resources to South32 for review. The estimates of Mineral Resources were reported in compliance with NI 43-101 using independent consultants, AMC Mining Consultants (Canada) Ltd (AMC). The Qualified Person (as required by Canadian securities regulatory authorities) for the Mineral Resource estimate was Dinara Nussipakynova, P.Geo, an employee of AMC.

The basis for the estimate as provided to South32 consists of a geological database incorporating geology, analytical results and surface topography. Mining and processing recoveries are based on the PEA completed by Arizona Mining for the Hermosa Project (Taylor and Central Deposit). The PEA dated 16 January 2018 is available on SEDAR (www.sedar.com). 

South32 believes that the information provided is the most recent publicly available. Following completion of the transaction it is South32’s intention to conduct a work program to increase confidence in the resource to ensure that resources are reported in accordance with the JORC Code. The work program will include additional exploration by means of drilling and is anticipated to be completed within three years and will be funded using internal cash reserves.

Cautionary statement:

• The estimates of Mineral Resources for the Hermosa Project (Arizona Mining) are foreign estimates under the ASX Listing Rules and are not reported in accordance with the JORC Code.
• Competent persons have not done sufficient work to classify the foreign estimates as Mineral Resources in accordance with the JORC Code.
• It is uncertain, that following evaluation and further exploration, the foreign estimates will be able to be reported as Mineral Resources in accordance with the JORC code.

Competent persons’ statement

In accordance with ASX listing rule 5.12, Matthew Readford, a Competent Person, employee of South32 and Member of the Australasian Institute of Mining and Metallurgy, confirms the information in this market announcement that relates to the Hermosa Project NI 43-101 foreign estimate filed on SEDAR (www.sedar.com) on 16 January 2018 is an accurate representation of the available data and studies for Hermosa Project provided to South32 by Arizona Mining. Matthew Readford has sufficient relevant experience for the type of deposit and method of extraction to qualify as a competent person in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (The JORC Code). Mr Readford consents to the inclusion in the report of the matters based on their information in the form and context in which it appears.
