NMC Resource (TSX VENTURE:NRC) Substantially Increases Mineral Resources at High Grade Producing Moland Mine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 1, 2011) -



NMC Resource Corporation (TSX VENTURE:NRC) ("NMC Resource") is pleased to announce an updated mineral resource estimate for the NMC Moland Mine in South Korea. At a potentially economic cut-off of 0.14% MoS2, total Indicated mineral resources are 1.669 million tonnes grading 0.35% MoS2 and the Inferred mineral resources are approximately 2.094 million tonnes grading 0.32% MoS2, which reflects a considerable increase in tonnage compared to the previous October 2009 mineral resource estimate. The updated mineral resource estimate is based on 88 drillhole records and 1,938 channel samples.

Cut-off (MoS2%) Indicated Inferred
Tonnes (1000 t ) MoS2 (% ) Tonnes (1000 t ) MoS2 (% )
0.14 1,669 0.35 2,094 0.32

Do Hyung Kim, Executive VP and Director states, "We are very pleased to see the mineral resource more than double, even using a 40% higher cut-off grade than the previous resource estimate. KORES (Korea Resource Corporation) continues to sponsor our deep drilling exploration and we will notify the market of results when they are received."

In order to test the sensitivity of the mineral resource estimate to the MoS2 cut-off, mineralized tonnage sensitivity was also tabulated against a range of cut-off grades.

(1) Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

(2) The quantity and grade of reported Inferred resources are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resources, and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resources category.

(3) Mineral resources were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.

(4) Inverse distance weighting of capped composite grades within grade envelopes was used for estimation.

(5) Composite grade capping of 3.0% was implemented prior to estimation.

(6) A bulk density of 3.34 t/m3 was used for tonnage calculations.

(7) The cut-off grade calculation was based on the following parameters:

  • US$16/lb Molybdenum
  • US$11/t mining cost
  • US$13/t process cost
  • US$1.75/t G&A cost
  • 89% process recovery
  • 59% smelter payable Mo in MoS2
  • US$20/t concentrate shipping
  • 0.3% Mass pull to concentrate

(8) A lower cut-off grade may be used for production when molybdenum price increases or operating costs decrease.

The mineral resource estimate was completed by Fred H. Brown, CPG, Pr.Sci.Nat., who is an independent geological consultant associated with P&E Mining Consultants Inc. ("P&E") and an independent qualified person "QP" as defined by Canadian Securities Regulations in National Instrument 43-101. The primary analytical facility for NMC Moland Mine is ALS Chemex, which is located in North Vancouver, BC, Canada. Further details of the estimation procedure will be available in a NI 43-101 technical report, which will be posted on SEDAR no later than 45 days from the date of this news release.

Check Samples

During a site visit to NMC Moland Mine in September 2011, P&E collected five check samples from drillhole core, and six check samples from on-site pulps. For the eleven samples, two drillhole core samples appear to be from a different drillhole sequence due to a change in drillhole numbering for the NMK series. The remaining assay results for the check samples are in good agreement with the assay values as reported by NMC Resource.


A bulk density value of 3.34 t/m3 was used for the mineral resource model, consistent with the bulk density used for the October 2009 mineral resource estimate. The average bulk density of the check samples taken by P&E is 3.46 t/m3. Based on decile analysis of the composite sample population, a capping value of 3.0% MoS2 was implemented on composites prior to estimation. A total of eleven composites were capped. Block grades for MoS2 were estimated using anisotropic inverse distance cubed (ID3) linear weighting of capped composites. Mined out areas as identified by NMC Resource were depleted from the model.

NMC Moland Mine

NMC Moland Mine has been in commercial production since April 2010 and continues to provide NMC Resource with a stable revenue stream. The process plant crushing facility at NMC Moland Mine is located underground, and 100% of the process water is recycled. NMC Moland Mine does not have a tailings pond since all tailings are used in the manufacture of cement.
