Mindoro Significantly Increases Agata Nickel Resources
• Measured and Indicated resources up 31% to 42.76 million tonnes @ 1.01% nickel
• Drilling to continue testing five remaining regional targets
MELBOURNE, AUSTRALIA, September 16, 2011 -- Mindoro Resources Ltd (TSXV: MIO; ASX: MDO; Frankfurt: WKN 906167) has increased its Mineral Resource estimate for the Agata Nickel Project, including Surigao regional targets. This includes a total Measured and Indicated resource of 42.76 million tonnes at 1.01% nickel for 430,000 tonnes contained nickel, an increase of 10.1 million tonnes or 31% compared to the September 2010 estimate, with a slight decrease in grade. In addition, the total Inferred resource has increased by 0.75 million tonnes to 2.435 million tonnes at 0.99% nickel. Total mineral resource estimates are tabulated below:
Company President and CEO Jon Dugdale said, "This significant increase to the resource base at Agata Nickel Project and regionally will provide for additional mine life beyond the 15-year project described in the March 2011 PEA. Additionally, it provides the opportunity for early production based on high-iron limonite at the top of the laterite profile."
The total resource estimate consolidates four separate deposits: Bolobolo and Karihatag prospects located approximately 20 km north of Agata (North); Agata South located approximately 5 km south of Agata (North) and the resource estimates for Agata North released 8 September 2010. All resources are located within 2 km of the coast. The Agata South resource is located within the Agata MPSA, that has a granted Environmental Compliance Certificate (ECC) for up to two million dry metric tonnes of shipping ore production per annum. Bolobolo and Karihatag are located on a granted Exploration Permit (EP).
A total of five regional exploration targets have now been tested: Bolobolo, Karihatag and Agata South where resources have been defined, and Tapian East and Canaga where no resource has been defined to date due to lack of continuity between isolated intercepts. Mapped laterite exploration targets not yet drill-tested include San Jose, Tapian Central (Mamatfa), Tapian West (Corplex), Villariza and Mat-I. Drilling will continue as access to these areas is improved. The remaining Exploration Target for these areas is under review and subject to initial drilling to determine thickness.

Mineral resource estimates for Agata Nickel Project and Surigao regional projects are tabulated below:
The Company has increased total Measured and Indicated resources by nearly 60% over the 2010/2011 drilling programs, as shown in the graph below:
The mineral resource estimates were produced by Mark Gifford MSc (Hons), who is a Fellow of the Australian Institute of Mining and Metallurgy (FAusIMM) and an independent qualified person as defined by NI 43-101, in conjunction with Quantitative Group Pty Ltd (QG) in Perth, Australia. A total of 487 additional drill core holes for 5,649 metres of drill core were used for additional resource estimate, taking the total number of holes used in the resource estimate, including Agata North, to 1,080 for 16,500 metres. The resource estimation method applied was Ordinary Kriging, a very robust and proven methodology with regards to lateritic nickel deposits. Cut-off grades applied to the resource were 0.5% nickel within the Limonite zone and 0.8% nickel within the Saprolite zone.
Sample preparation and assaying were performed by Intertek Testing Services, Phils., Inc. (ITS). The ITS Phils. facility is among Intertek's global network of mineral testing laboratories. It provides high quality assay analysis of mineral samples for nickel deposit exploration projects. Each sample is analyzed for nickel (Ni), cobalt (Co), iron (Fe), magnesium (Mg), aluminum (Al), silica (SiO2), CaO, Cr2O3, K2O, MnO, Na2O, P2O5, and TiO2. Whole rock analyses are done using X-ray Fluorescence (XRF). The samples are fused using lithium metaborate. XRF analysis determines total element concentrations that are reported as oxides. Intertek mineral testing laboratories implement quality protocols. Normal Quality Control and Quality Assurance procedures are being carried out, using a system of repeat analyses plus split sample analyses and the use of standard reference materials and blanks. Mindoro has also conducted assay verification using standard samples and re-assaying field and pulp duplicates.
Mark Gifford, FAusIMM, has indicated that the density of drilling and continuity of mineralization is sufficient to classify the estimated resource and has verified and authorized the technical information detailed in this release.
The NI 43-101 technical reports will be filed on SEDAR within 45 days of the date of this release.

Mindoro is a Tier 1 Issuer trading on the TSX Venture Exchange (MIO), Australian Securities Exchange (MDO) and Frankfurt Stock Exchange (WKN 906167). Mindoro is focused on nickel exploration and development and copper and gold exploration in the Philippines with a strategy of advancing early-stage opportunities to production or joint venture.
Mindoro has NI 43-101 Mineral Resource estimates on its Agata Nickel Project, in the Surigao District, Mindanao, that include Measured and Indicated resources totalling 42.76 million tonnes at 1.01% nickel, for 430,000 tonnes contained nickel, and Inferred resource estimates totalling 2.435 million tonnes at 0.99% nickel. In addition the Company has NI 43-101 Mineral Resource estimates on its Lobo (2005) and Archangel (2010) gold-silver projects, as well as 10 key porphyry copper-gold prospects at varying stages of advancement.
In March 2011 Mindoro released a preliminary economic assessment (PEA) on the Agata Nickel Project where the Company controls major nickel laterite resources and is drill testing regional targets. The Company is completing a prefeasibility study (PFS) into an integrated on site nickel processing project, based on the PEA, that is due for release in October 2011. The Company is also close to completing a scoping study into the development of a thermally upgraded (sintered) iron-nickel ore operation to generate early cash flow. The scoping study is due to be completed in late September 2011.
The recently drill tested Pan de Azucar gold-copper massive sulphide remains open with depth to the southeast. A metallurgical testing program has commenced on Pan de Azucar samples examining acid producing capacity for nickel laterite processing as well as copper and gold flotation and leaching. Mindoro has commenced drilling to expand gold resources at Lobo, Batangas, and is evaluating and prioritizing its many high-potential copper-gold porphyry targets prior to further drill targeting.
