Mindoro Resources Ltd.: Further Positive Drill Results From Agata Nickel Laterite

EDMONTON, ALBERTA--(Marketwire - Aug. 14, 2007) - Mindoro Resources Ltd. (TSX VENTURE:MIO)(FRANKFURT: WKN 906167) is pleased to report results from a further thirteen drill holes on two drill cross sections; 10250N and 10300N on the Agata nickel laterite project, Philippines. For section 10250N the limonite horizon averages 1.10 percent nickel and 42.67 percent iron over an average thickness of 8.45 meters. For section 10300N, 50 meters to the north, the limonite horizon averages 0.95 percent nickel and 41.46 percent iron over an average thickness of 5.73 meters. The underlying saprolite horizon on section 10250N averages 0.95 percent nickel over an average thickness of 6.10 meters, while for section 10300N the saprolite horizon averages 1.25 percent nickel over an average thickness of 5.73 meters. Mineralization grades and thicknesses meet Company expectations and are in line with requirements for direct shipping grade material for ferro-nickel feedstock. Notwithstanding the recent softening of nickel price, demand remains for ferro-nickel feedstock.

As reported on March 13, 2007, the company's current objective on the Agata nickel laterite project is to define a NI 43-101 compliant resource adequate, initially, for three to five years of production at a rate of 500,000 to 700,000 wet metric tonnes per annum of direct shipping-grade material for the very high demand ferro-nickel markets of China, India and Korea. Mindoro has a target production date of the first half of 2008, and would ramp up production to one million tones or more per year thereafter depending on market demand. The initial drill program covers less then ten percent of the area of nickel laterite mineralization mapped to date at Agata. On June 20, 2007, Mindoro released a revised global Exploration Target for the northern part of the Agata Project (see "About The Agata Nickel Laterite Project" below).

Results from sections 10250N and 10300N are consistent with the previously reported sections 9950N, 10000N, 10050N, 10100N, 10150N and 10200N (see news releases dated June 6 and 18, July 3, 2007). Mineralization is wide open to the east on both sections. A drill location map accompanies this release on Mindoro's website, as well as two cross sections showing assay results. The iron-rich overburden above the limonite horizon also has high iron content in the range of 38 to 42 percent, as well as 0.65 to 0.66 percent nickel, and has potential for blending purposes. The nickel and iron grades of the limonite horizon are robust, consistent between all eight sections reported to date, and are in line with grade requirements for ferro-nickel feedstock.

Mindoro management considers the results to date form a sound basis for fast-tracking the project. The Environmental Compliance Certificate is well advanced and the recently hired mine manager is advancing mine design planning (see release of July 13, 2007).

ABOUT THE AGATA NICKEL LATERITE PROJECT

The nickel laterite prospect is situated on the Agata Project, Surigao Gold District, northern Mindanao, Philippines. There are several nickel laterite mines already in production in the Surigao District, providing direct shipping-grade ore to markets and processing plants in China, Japan, Korea and Australia. The geological extension of the Agata nickel laterite mineralization into an adjacent property, one kilometer south of Agata, is in production and product is being shipped to markets in China (see map accompanying this release). Mindoro's Exploration Target for the various laterite horizons in the northern laterite area is as follows:

Combined ferruginous overburden, limonite and saprolite horizons: 50 to 60 million wet metric tonnes (WMT) at a grade of 0.9 to 1.1 percent nickel and 28 to 32 percent iron. This includes the following division of tonnage between the overburden/limonite horizon and the saprolite horizon:

- Combined ferruginous overburden and limonite horizons: 30 to 35 million WMT of material at a grade of 0.9 to 1.1 percent nickel and 40 to 44 percent iron.

- Underlying saprolite horizon: 20 to 25 million WMT of material at a grade of 1.0 to 1.4 percent nickel and 8 to 10 percent iron.

The northern nickel laterite mineralization covers approximately 340 hectares. As shown on the accompanying map, a total of over 90 drill holes has been completed to date within this area. Average thicknesses and grades encountered and a specific gravity of 1.5 grams per cubic centimeter were used to arrive at the revised Exploration Target. The Exploration Target does not include significant thicknesses of low-grade, partially lateritized saprolitic rock, grading in the 0.6 to 0.8 percent nickel range, that also has market potential. Nor does it include additional areas of nickel laterite mineralization further south on the Agata Project.

This revised Exploration Target will form the basis for evaluating several attractive value-added processing options, which includes constructing a local blast or electric furnace for nickel pig iron production. In the meantime, Mindoro will continue to fast-track the direct shipping ore scenario with the objective of achieving production in 2008. Uniquely, direct shipping grade nickel laterite deposits have a low-capital cost and offer a rapid route to production and cash-flow.

The reader is cautioned that the potential quantity and grade of the Exploration Target described is conceptual in nature, that there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resource. Until a feasibility study has been completed there is no certainty that the Company's projections will be economically viable.

Programs are carried out under the supervision of Tony Climie, P.Geol., president of Mindoro, who is a qualified person as defined by National Instrument 43-101. Sample preparation and assaying is being performed by McPhar Laboratory of Manila, an ISO 9001/2000 accredited laboratory. Ni, Co, Fe, MgO and Al2O3 assays are performed by AAS after an HCl-HNO3-HClO4 digest, and SiO2 by gravimetric method. Normal Quality Control and Quality Assurance procedures are being carried out, using a system of duplicate, standard and blank samples.

The company has also identified 22 porphyry copper-gold prospects in the Philippines and has an aggressive strategy of drilling multiple targets in 2007.

This release may contain forward-looking statements including management's assessments of future plans and operations, and expectations of future production. These statements are based on current expectations that involve a number of risks and uncertainties, which could cause actual results to differ materially from those anticipated. These risks include, but are not limited to, the risks associated with the mining and exploration industry (e.g. operational risks in development, exploration and production; delays or changes in plans with respect to exploration or development projects or capital expenditures; the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to production). The assumptions used in the preparation of such statements, although considered reasonable at the time of preparation, may prove to be imprecise and, as such, undue reliance should not be placed on forward-looking statements.

The TSX Venture Exchange has not reviewed and does not accept responsibility for the adequacy or accuracy of this release.
