CALGARY, ALBERTA, June 24, 2013 - Mindoro Resources Ltd. (TSXV: MIO; ASX: MDO; Frankfurt: WKN 906167) is pleased to announce that it has signed a secured promissory note to receive up to CAD $1.3 million from joint venture partner TVI Pacifc Inc. The loan will be used to fund operations for the next twelve months and finance an initial acquisition payment to Minimax Mineral Exploration Corporation for the remaining 25% interest in the Agata project.

Mindoro is negotiating to acquire the additional interest from Minimax, which will give Mindoro a 40% interest in the Agata high iron laterite direct shipping operation (DSO), limestone DSO operation, and Agata processing operation, once TVI earns its 60% interest in these projects. As previously disclosed in Mindoro's press release of February 13, 2013, the Agata nickel project is being advanced under the following two stage development objective:

• Stage 1: undertake feasibility study and permitting for a DSO project, leading, subject to economic viability, to commencing a DSO operation in late 2013.
• Stage 2: advance preferred processing technology to pilot testing, followed by a definitive feasibility study by the end of 2013. As disclosed in Mindoro's June 6, 2013, press release, TVI has commenced pilot-plant testing which will further define the technological parameters to be used in producing a Bankable Feasibility Study.

Terms of the Promissory Note

Mindoro may receive up to CAD $1.3 million from TVI pursuant to an agreed upon schedule of monthly draws. Funds will be repayable within twelve months of the first draw down; however, there is no minimum draw down amount and funds, plus interest, may be repaid at an earlier date without penalty. Mindoro will accrue interest at the greater of 15% per annum or TVI's cost of capital for funds obtained for this purpose. The promissory note is secured by shares in Mindoro's wholly owned subsidiary, MRL Nickel Philippines Inc.

Joint Venture Amendments

Mindoro and TVI have also agreed to amend the following terms of the original joint venture agreements, as previously disclosed in Mindoro's July 6, September 7, and September 27, 2012, press releases:

• TVI's contributions to the Agata Mining Joint Venture and Agata Processing Joint Venture will be for shares in the applicable joint venture, rather than as paid in capital, with such shares to be issued as earned and placed in escrow until TVI's full 60% interest is earned. TVI will not retain any interest in the Agata Mining Joint Venture if it withdraws prior to commencing a DSO operation and will not retain any interest in the Agata Processing Joint Venure if it withdraws prior to completing a Definitive Feasibility Study.
• TVI's minimum spending commitments pursuant to the Pan de Azucar Joint Venture agreements are extended by one year, from December 31, 2013, to December 31, 2014.

On behalf of the Board of Directors,
Tony Climie
CEO
