Mindoro Resources: New Resource Estimate for Agata North Provides a Strong Foundation for early DSO Production
Mindoro Resources: New Resource Estimate for Agata North Provides a Strong Foundation for early DSO Production
CALGARY, ALBERTA, April 11, 2013 - Mindoro Resources Ltd. (TSXV: MIO; ASX: MDO; Frankfurt: WKN 906167) (“Mindoro”) advises that joint venture partner TVI Pacific Inc. (TSX:TVI) (OTCQX:TVIPF) (“TVI”), and its Philippines operating subsidiary TVIRD, has filed an updated National Instrument 43-101 (NI 43-101) technical report. The independent technical report is entitled "Independent Report on the Nickel Laterite Resource – Agata North, Philippines.” The report was prepared by Mark G Gifford, MSc (Hons), FAusIMM, of Margaret River, Western Australia. The NI 43-101 technical report will be filed on Mindoro’s SEDAR profile at www.sedar.com and on Mindoro’s website at www.mindoro.com within a week of the date of this release.
The NI 43-101 reflects an updated and reclassified resource estimate for the Agata North nickel laterite resource. The new resource provides a robust foundation for moving forward, initially, with a direct shipping operation (DSO) of high-iron limonite (upper laterite horizon), followed by atmospheric leach processing of the underlying saprolite horizon.
• Measured and Indicated resources increase to 33.9 million dry metric tonnes (dmt) at 1.1% nickel compared to the previous 31.8 million dmt at 1.05% nickel
• Inferred resources are 2.0 million dmt at 1.04% nickel
• At a cut-off grade of 44% iron, there are an estimated 7.9 million dmt or about 10 million wmt at 48.5% iron and 0.94% nickel – a DSO product grade currently much in demand in China
• The joint venture is fast-tracking DSO development and is targeting production in late 2013
The previous Agata resource estimate was carried out in 2011 (see Mindoro news release dated Sept. 16, 2011). This current resource estimate gives a superior grade-tonnage distribution. Sufficient high-iron limonite has been defined for approximately 5 years of DSO production at approximately 2 million dmt per year. During this period, it is expected that the processing plant will be in operation.
The table below shows results of the resource estimate at a cut-off grade of 0.5% nickel for the limonite horizon and 0.8% nickel for the saprolite horizon. This resource estimate is exclusive of the other regional nickel laterite deposits being Agata South, Bolo-bolo and Karihatag.

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 593 drill holes drill were completed at Agata North for 10,851 metres, and 11,100 core samples were used in the resource estimate. The resource estimation method applied was Ordinary Kriging. 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 Philippines facility is among Intertek's global network of mineral testing laboratories. Each sample is analyzed for nickel (Ni), cobalt (Co), iron (Fe), magnesium (Mg), aluminum (Al), silica (SiO2), Calcium Oxide (CaO), Chromium(III) Oxide (Cr2O3), Potassium Oxide (K2O), Manganese(II) oxide (MnO), Sodium oxide (Na2O), Phosphorus(V) oxide (P2O5), and Titanium dioxide (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 were carried out, using a system of repeat analyses plus split sample analyses and the use of standard reference materials and blanks. Assay verification was carried out 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.
High-Iron and Limestone DSO/Lime Production Facility
TVI further reports that both the high-iron DSO and the limestone DSO are near-term opportunities that have the potential to generate strong cash flows beginning in late 2013 (contingent on, among other things, receipt of permits in a timely manner). The high-iron laterite and limestone deposits occur one kilometre from the coast, which is expected to minimize transportation costs due to the close proximity of the mine pit to the port.
The upper portions of the laterite profile comprise the ferruginous zone and limonite zone, both rich in iron. The deposit is expected to be developed as a surface mining operation with the high-iron material sold to the Chinese iron ore market.
Beneath the ferruginous and limonite zone is the higher nickel grade saprolite zone, which will be the dominant feed for a new nickel processing facility currently under consideration by the Project Execution/Technology Development team. The high-iron DSO operation would be expected to generate early cash flow before the nickel processing plant is built and put into operation, but shipments are expected to continue after this until the high-iron material is exhausted. The high-iron DSO operation already has an existing Environmental Compliance Certificate (ECC); however, other permits such as a port permit and a Declaration of Mining Project Feasibility are also required.
The limestone occurring at the coast is a massive recrystallized limestone of very high purity levels with Calcium Carbonate (CaCO3) greater than 95% according to the Agata Report. The initial plan is to develop a resource, mine, and ship limestone DSO utilizing the infrastructure developed initially for the high-iron DSO. Currently no permits are in place for mining the limestone.
Since the quality of limestone quarried at Agata is expected to be high, the Project Execution/Technology Development team also plans to construct a lime production facility at the Agata project site. The lime produced would be used in the nickel processing plant, offsetting the costs of imported lime while also creating potential for some to be sold. The lime processing facility is a medium-term project currently expected to come online at the beginning of 2015 pending the receipt of all required permits, among other things.

Tony Climie
