Kubuk Resource Upgrade

Indicated Resources Now Defined

 

Amur Minerals Corporation ("Amur" or the "Company"), the nickel copper exploration and development company focused on base metal projects located in the far east of Russia, is pleased to announce that the Kubuk maiden resource estimate compiled by SRK Consulting Ltd ("SRK") in December 2013 has been re-evaluated and subsequently upgraded.  The upgrade completed by SRK is based on available quality control external analytical results that independently confirm the original analytical results used to compile the maiden estimate.  The verification of the validity of the data used to determine the maiden estimate allows for a reclassification of a portion of the resource from Inferred to Indicated.  The newly defined Indicated resource represents 17% of the total Kubuk resource estimate and contains 23,400 tonnes of nickel and 6,100 tonnes of copper.  The 3.5 million tonnes of Indicated resource averages 0.68% nickel and 0.18% copper.  Highlights include the following:

 

Highlights:

 

·     The maiden Kubuk resource estimate contained 20.6 million tonnes of ore averaging 0.58% Ni and 0.16% Cu per tonne.  The total contained nickel was 118,900 tonnes and copper was 32,900 tonnes.  The entire maiden resource was assigned the JORC compatible resource of Inferred.  There was no other category of resource included in the maiden estimate.

 

·     The comprehensive assignment of Inferred resource was partially due to the unavailability of independent external control analyses which are now available and have been reviewed by SRK.  SRK has concluded that the nickel and copper values determined during the compilation of the maiden resource are based on independently verified information allowing for a portion of the maiden resource to be upgraded in resource classification.   

 

·     The newly defined Indicated resource at Kubuk now stands at 3.5 million tonnes with an average nickel grade of 0.68% and copper grade of 0.18%.  Platinum and palladium are projected to average 0.1 g/t for each metal.  The total nickel tonnage is 23,400 and for copper is 6,100 tonnes. 

 

·     The Inferred resource has been reduced as a result of this upgrade and now stands at 17.1 million tonnes averaging 0.56% nickel and 0.16% copper.  The total tonnage of nickel for the Inferred category is now 95,500 tonnes with the Inferred copper tonnage being 26,800 tonnes.

 

·     The majority of this newly defined Kubuk Indicated resource is contained within the Conceptual Pit designs for the 6.0 million tonne per annum operation planned by the Company.

The resource reclassification at Kubuk has multiple impacts on the project.  The first of which is a reduction of in-fill drilling to confirm the resource available to open pit mining.  Secondly, the confidence in the resource and reserves derived for the newly classified model is increased and portions can be utilised in bankable study work planned for the future.

 

Robin Young, CEO of Amur Minerals Corporation, commented:

 

"The conversion of Inferred to Indicated resource represents nearly 20% of the contained nickel at Kubuk and more than 50% of the ore tonnage defined in the Conceptual Pit Study.  This could reduce the in-fill drilling of the Kubuk open pit resource target by as much as 50%.  As we await the final decision by the Russian government on the award of the production licence, we shall continue to advance the project and optimise our work plan looking to the future."

Glossary

 

DEFINITIONS OF EXPLORATION RESULTS, RESOURCES & RESERVES

EXTRACTED FROM THE JORC CODE: (December 2012) (www.jorc.org)

 

A 'Mineral Resource' is a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.

 

An 'Inferred Mineral Resource' is that part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability.

 

An 'Indicated Mineral Resource' is that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed.

 

A 'Measured Mineral Resource' is that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence. It is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are spaced closely enough to confirm geological and/or grade continuity.

 

An 'Ore Reserve' is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses which may occur when the material is mined. Appropriate assessments and studies have been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified. Ore Reserves are sub-divided in order of increasing confidence into Probable Ore Reserves and Proved Ore Reserves.
