Increased Agata Nickel Resource and Regional Drilling Commenced

EDMONTON, ALBERTA - Mindoro Resources Ltd. (TSXV: MIO; Frankfurt: WKN 906167) today announced an increased Mineral Resource estimate for the Agata Nickel Project.  This includes a Measured and Indicated resource of 29.8 million tonnes at 1.03 percent nickel, an increase of 2.9 million tonnes compared to the December 2009 estimate with a slight decrease in grade due to a more robust estimation methodology and more detailed information.  In addition an Inferred resource of 1.46 million tonnes at 1.01 percent nickel has been estimated.

The mineral resource estimate is tabulated below.

• The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing or other relevant issues..

The new resource estimate was carried out by Mark Gifford MSc (Hons), MAusIMM an independent qualified person as defined by NI 43-101, in conjunction with Quantitative Group in Perth, Australia.  A total of 593 drill core holes for 10,851m of diamond drill core were used for the estimate. The resource estimation method applied was Ordinary Kriging, a very robust and proven methodology with regards to lateritic nickel deposits. All previous resource estimates were completed by a length-weighted inverse distance squared method to provide an indicative resource appropriate to the drilling density at the time of reporting. Cut-off grades applied to the resource were 0.5 percent within the Limonite zone and 0.8 percent within the Saprolite zone.  Mr. Gifford 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. . Mr. Mark Gifford has 22 years of experience as a professional geologist including in a geological managerial position at the Murrin Murrin nickel laterite operation in Western Australia and experience on other Nickel Laterite projects around the world.  The Ni 43-101 compliant technical report will be filed on SEDAR within 45 days.

In addition a scoping study has been initiated through Hatch engineering group in Perth into low-capital cost, thermal upgrading technologies, such as sintering, to produce much higher-value iron and iron-nickel products from the Limonitic ores. These have the potential to quickly phase out the shipping of raw DSO product, and to form an intermediate development stage prior to a major acid-leach processing operation.  The major acid-leach project scoping studies, including additional metallurgical testing, are due for completion late September 2010. 

The reader is cautioned that the potential quantity and grade of the Exploration Target is conceptual in nature; it is uncertain if further exploration will result in the Exploration Target being delineated as a mineral resource and there is no guarantee that these resources, if delineated, will be economic or sufficient to support a commercial mining operation. The company�s production objectives are intended to provide an indication of management�s current expectations and are still conceptual in nature. It is uncertain that it will be established that these resources will be converted into economically viable mining reserves. Until a feasibility study has been completed, there is no certainty that these objectives will be met.

Tony Climie, P.Geol, is the company�s Qualified Person as defined by National Instrument 43-101, who is responsible for monitoring the supervision and quality control of Mindoro's exploration programs and who has reviewed and verified the technical information contained in this news release. 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
