Mindoro Proposes Major Restructure of Philippines Assets

- Mindoro to spin-out key gold and copper-gold assets to ASX listed Red Mountain Mining Ltd

- Mindoro close to finalizing strategic partnership to advance Agata Nickel Project to production

- Board and management changes for nickel-cobalt-copper development focused Mindoro

MELBOURNE, AUSTRALIA -- (Marketwire - May 29, 2012) - Mindoro Resources Ltd. (TSX VENTURE:MIO) (ASX:MDO) (FRANKFURT:OLM) (Mindoro, "the Company") is pleased to announce a proposed major restructure of its Philippines assets. The purpose of the restructure is to spin-out the key gold and copper-gold assets, namely the Batangas gold projects including Archangel and Lobo, and the Tapian San Francisco (TSF) copper-gold properties near Surigao, into ASX listed Red Mountain Mining Ltd ("Red Mountain"). The parties have signed a non-binding, conditional term sheet in relation to these aspects. The consideration for the sale of the assets is shares in Red Mountain payable to Mindoro in two tranches as follows:

i. 100 million initially non-voting shares at nominal A$0.10 per share on completion of the transaction; and

ii. 50 million "Performance Shares" at a nominal A$0.10 per share to convert to non-voting shares based on upgrading the Indicated Resource at Batangas to 600,000 oz of gold and completing a scoping study that demonstrates a viable gold project based on over 50% of the indicated resource within 12 months of completing the transaction, which the parties will use their best endeavors to achieve. The Performance Shares are cancelled after 12 months if the above objectives are not achieved.


Subject to approval from the Australian Securities Exchange, the non-voting shares will carry full economic rights but will not carry any voting rights until such time that the non-voting shares are distributed to Mindoro shareholders. Mindoro intends to distribute these shares to Mindoro shareholders in specie on a pro rata basis within 12 months of completing the transaction or following any escrow period that may be applied by the ASX. The shares issued to Mindoro will be non-voting until the earlier of the distribution to Mindoro shareholders being made or Mindoro having a relevant interest in less than 20% of Red Mountain shares. Until the distribution is made (or for 12 months from completion, whichever is sooner), Red Mountain will require Mindoro approval to undertake various corporate actions including dealing with the gold and copper-gold assets. The Term Sheet contemplates that Red Mountain will become a reporting issuer in the jurisdictions in Canada where the Company has resident shareholders through the filing of a prospectus to qualify the Distribution and allow for the resale of Red Mountain shares received by the Company's shareholders.

Mindoro President and CEO Jon Dugdale said, "the separation of the key gold and copper-gold assets of the company from the advanced Agata nickel project provides the opportunity for optimal value recognition of these assets in today's equity marketplace. This is why the Board and Management of Mindoro supports this proposed spin-out of the Batangas and TSF gold and copper-gold projects into the gold mining and exploration focused Red Mountain. Red Mountain's mining expertise and funding with the Mindoro team's exploration and community engagement track record, is a great combination."

Red Mountain had approximately A$5 million in working capital at the end of March 2012. Red Mountain's Chairman and acting CEO is Neil Warburton who, until recently (March 2012), was the CEO of leading Australian underground mining contractor, Barminco Limited. Upon completion of the transaction Mindoro President and CEO Jon Dugdale will become an Executive Director of Red Mountain and Mindoro's Vice Chairman Howard Walker will become a non-executive Director of Red Mountain. Red Mountain and Mindoro contemplate that within nine months of completion of the transaction Jon Dugdale will transition to the role of Managing Director of Red Mountain and that Neil Warburton will become a Non-Executive Chairman. It is anticipated that Mindoro will have made the transition to a nickel development company within this nine month period.

As part of the transaction Red Mountain will provide a secured draw-down facility for up to A$1 million to enable Mindoro to commence drilling, focused on delineating the high-grade "feeder" structures below the Kay Tanda resource at Archangel, Batangas.

Mindoro and Red Mountain are continuing with a due diligence period and anticipate signing a binding agreement on or before June 15th 2012

The sale of the Batangas and TSF projects to Red Mountain will require approval by Mindoro shareholders. Materials have been dispatched regarding the sale for consideration and vote at the Mindoro Annual General Meeting, to be held June 27th, 2012 in Calgary, Canada, and to be video-linked from Melbourne on June 28th. Red Mountain shareholder approval for the transaction will also be required in addition to various regulatory approvals including by the TSX Venture Exchange.

The Board and management of Mindoro believe that the Company is receiving fair value for the Batangas Gold Project and TSF assets. The consideration being paid in Red Mountain shares offers the following value opportunities for shareholders:

i. Transaction value of A$10 million to A$15 million or C$0.06 per Mindoro share assuming performance shares are converted to non-voting shares prior to any further equity raising.

ii. The transaction matches the gold and copper-gold assets with over $4.2 million in funding with the majority to be focussed on drilling key gold and copper-gold targets, building the gold resource base and completing a scoping study.

iii. Upon completion of the transaction Mindoro shareholders, either through their holding in Mindoro, or following in specie distribution, and assuming performance shares are converted to non-voting shares, are expected to hold up to 65% of Red Mountain's issued capital. This provides high exposure to gold and copper-gold exploration upside in a gold-focused listed company.

iv. Red Mountain's board and management have gold mining and project development experience complimentary to the Mindoro team's core skills in exploration and discovery as well as community relations in the Philippines.

Assuming (i) Mindoro and Red Mountain successfully negotiate and sign a binding agreement reflecting the terms and conditions of the transaction as set out in the non-binding term sheet; (ii) the shareholders of both Mindoro and Red Mountain approve such transaction; and (iii) all required regulatory approvals are received, including approval from the TSX Venture Exchange, the completion of the sale, including all conditions precedent, is expected to occur early to mid-August 2012.


Status of the Agata Nickel Project Strategic Partnership

The spin-out of Mindoro's key gold and copper-gold assets will allow the Company to focus on completing the Agata Nickel Project (ANP) strategic partnership to advance the project to development and production in two stages.

The ANP includes a 42Mt @ 1.01% Ni (430,000t Ni)(1) Measured and Indicated Resource and a 35.4Mt @ 1.03% Ni (365,000t Ni)(2) Proved and Probable Reserve. The objective of the Company is to establish a strategic funding partnership to accelerate a two-stage development strategy including stage 1 direct shipping ore (DSO) production and stage 2 hydro-metallurgical processing to definitive feasibility study (DFS).

The Company is in advanced discussions with a group aiming to secure a strategic stake in the ANP through providing funding to establish DSO production and complete pilot testing and a DFS into a hydrometallurgical acid-leach processing operation.

Demand for nickel laterite DSO from the Philippines has been positively impacted since Indonesia has moved to restrict direct shipping of unprocessed nickel laterite ore from 2013. The DSO scoping study will be upgraded to a feasibility study and permitting will be upgraded from the current Environmental Compliance Certificate (ECC) to Declaration of Mining Project Feasibility once strategic partner financing and offtake agreements are finalised.

The Company is working with its financial advisor, Deloitte Corporate Finance Pty Ltd ("Deloitte"), with the objective of reaching preliminary agreement in the near future.


Mindoro's Board and Management Changes

Coinciding with the restructure there will be certain board retirements and executive changes that will affect the board and management structure of the Company.

President, CEO and Director Jon Dugdale, Chairman A Robson Garden, non-executive directors Doug Frondall and John Tosney as well as Vice Chairman and Director Howard Walker will be seeking reappointment to the Board at the Annual General Meeting on June 27th, 2012.

Tony Climie will not be standing for re-election to the board but will retain the key executive role as Mindoro's Philippines Country Manager, and President of wholly owned Mindoro operating subsidiary MRL Gold Phils. Inc. A Company director since 1994, Tony was CEO during the period when the key discoveries and relationships were established in the Philippines, upon which the Company is now looking to build significant shareholder value. Tony will continue to perform the key on-the-ground role within both sides of the new structure.

Oscar Reyes will not be standing for re-election to the board due to workload commitments with his role as President and CEO of Meralco, the Philippines largest power provider. Oscar will retain the role as Chairman of MRL Gold Phils. Inc.

Chris de Guingand will not be standing for re-election to the board. Chris recently retired as Chairman of nickel production company, Panoramic Resources Ltd. Chris will continue to offer his experience and guidance to the company as a consultant.

Howard Walker will return to being a non-executive Director, retaining the role of Vice Chairman.

(1) Announced 16 September 2011

(2) Announced 2 November 2011 and revised 22 December 2011 in Technical Report for the Agata Nickel Laterite Project (Pre-Feasibility Study), Ausenco.

Vice President, Commercial, and Chief Financial Officer Rob King will resign effective June 30th, 2012 to pursue other business interests in the mining equipment and services industry. Rob's service has been invaluable, particularly during the period leading up to the anticipated transactions described herein. Rob will be available for part time consulting services. Financial Controller, Clayton Northey, will take on the roles of CFO and interim Company Secretary, effective July 1st, 2012. Clayton holds a Bachelor of Commerce degree from the University of Alberta, Canada and joined the Company in 2007 as Accountant.

The Company recently expanded its search for advanced exploration and mining projects to the greater Asian region following several significant projects coming to its attention.

The Company's development and production objectives are intended to provide an indication of management's current expectations and are still conceptual in nature. It is uncertain that sufficient resources will be established and if established that these resources will be converted into economically viable mining reserves.
