OVERVIEW OF FOURTH QUARTER ACTIVITIES
Agata Nickel Project Development Strategy
The Company is progressing a two stage development strategy including thermally upgraded direct shipping ore followed by a low operating-cost nickel processing operation based on established acid leaching technology.
On October 6th 2010 the Company announced the results of the Agata Nickel Project Scoping Study that provided a preliminary assessment of the economics of three processing options, including a base case High Pressure Acid Leach (HPAL) -- Atmospheric Leach (AL) and Saprolite Neutralisation (SN) project ($2.50/lb Opex for 27,000t Nickel pa; 1.3Bn Capex) and an atmospheric leach only case ($3.25/lb Opex for 14,300t Ni pa, 740m Capex). The Company is currently examining a smaller scale approach to the base case processing project, based on the current Agata resource and results of the metallurgical testing program (see below). A preliminary economic assessment into the preferred development model is scheduled for completion Q1 2011, prior to the commencement of a pre-feasibility study.
On December 13, 2010 the Company announced the results from a comprehensive bench scale test work program on Agata samples by SGS Lakefield Oretest [a NATA accredited laboratory] in Perth. The hydrometallurgical test results demonstrated exceptionally fast leaching rates with high nickel and cobalt recoveries. HPAL testing extracted approximately 98 percent of the nickel and 95-96 percent of the cobalt from limonitic material within 20 minutes. This leaching rate is 50 percent faster for HPAL processing than previously assumed in the scoping study announced on October 2, 2010. Based on these results a second stage of testing was initiated in February 2011 with SGS Lakefield Oretest at their Canadian laboratory. The results of this testing will form the basis of the planned pre-feasibility study due to commence early in the second quarter of 2011.
In parallel with the acid leach processing work described above the Company has been progressing a preliminary direct shipping ore (DSO) study which will allow the Company to develop an economic model around this stage of the project as part of the preliminary economic assessment. In addition, on the 13th of October 2010 the Company announced it had completed a concept study through Hatch Associates Pty Limited, Perth, into thermal upgrading of nickel lateritic material at Agata. Based on the concept study the Company commenced bench-scale thermal upgrading testing, also at SGS Lakefield Oretest in Perth, the results of which are due by the end of the first quarter 2011. The Company is undertaking further review of markets for both DSO and thermally upgraded laterite product, and the capital and operating costs for their production, before incorporating this stage of the project into the planned pre-feasibility study.
Suriago Regional Exploration Target Drilling
A drilling program to convert a significant proportion of the regional Exploration Target to mineral resources commenced in the first week of August 2010. By year's end the Company had drilled a total of 309 holes for 3,458m of a planned 7,000m to 10,000m program.
On October 14th 2010 the Company announced the initial results from the Tapian and Canaga targets, that included results of potential economic interest but erratically distributed.
On January 12th and 24th 2011 the Company announced strong drill results of potential economic interest from the Bolobolo and Karihatag nickel targets located immediately to the south of Tapian. Highlights of the drilling include from Bolobolo: BBL-04: 7.30m @ 1.26% Ni from 1m, BBL-03: 7.15m @ 1.22% Ni from 3.8m and BBL-05: 6.45m @ 1.46% Ni from 2.7m and from Karihatag: KL-20: 6.60m @ 1.04% Ni from 1.6m, KL-21: 5.00m @ 1.00% Ni from 4.25m and KL-012: 4.90m @ 1.08% Ni from 7.75m and from Tapian: TML-05: 5.9m @ 1.17% Ni from 2.35m. Infill drilling is planned to continue on the Bolobolo and Karihatag targets to 50m x 50m centers for resource calculation prior to testing other targets such as San Jose and Villariza.
Copper Gold Exploration
At Pan de Azucar prospect located near Panay Island, central Philippines, the Company announced commencement of a 1,000 m drill program to further evaluate the potential of the Valderama massive pyritic sulphide body where promising gold, copper, silver and zinc values were intersected by Mindoro in two previous drill programs.
At Batangas, Luzon, Gold Fields limited has the right to earn up to a 75% interest in each of the El Paso, Lobo and Talahib porphyry copper-gold projects. In December, 2010 the Company announced that Gold Fields had commenced drilling at Lobo, testing high-grade epithermal gold targets as well as gold-copper porphyry targets. Approximately 2,200 meters of drilling is planned initially.
On behalf of the board of directors
President and CEO
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, 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-cobalt project
and NI 43-101 Mineral Resource estimates on its Lobo and Archangel (Kay Tanda) gold-silver projects, as well as an additional 22 porphyry copper-gold prospects. Senior gold producer, Gold Fields, may earn 75 percent interest in three of Mindoro's projects at Batangas through direct project expenditure.
Mindoro is assessing the potential to develop a value-added shipping ore nickel operation to generate early cash flow as well as large scale potential for an onsite processing plant in the Surigao District, Mindanao, where the Company controls major nickel laterite resources and is drill testing regional targets. An integrated preliminary economic assessment on the Agata nickel laterite project is expected to be completed in the first quarter of 2011, leading to commencement of a prefeasibility study into an integrated on site nickel processing project.
Three drill programs are currently in-progress on the Company's projects including regional nickel drilling at Surigao; copper-gold drilling at Pan de Azucar and gold and copper-gold drilling by Gold Fields at Lobo (Batangas).
Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
The Company's DSO and large scale 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. Until a feasibility study has been completed, there is no certainty that these objectives will be met.

Mr. Climie is an executive and a director of Mindoro and is a member of the of the Alberta Professional Engineers, Geologists and Geophysicists Association. Mr. Climie has more than five years of experience which is relevant to the style of mineralization and type of deposit under consideration and to the activity which he has undertaken. Mr. Climie has consented to the release of the technical information in the form and context in which it appears.
The Company's resource estimates were originally prepared in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum classification system. NI 43-101 is a rule developed by the Canadian Securities Administrators that governs how Canadian issuers disclose scientific and technical information about mineral projects and which is broadly equivalent to the JORC Code in Australia. All resource information is also expressed in terms of the JORC Code.
