Erdene Receives Independent Technical Report on Donkin Export Coking Coal Project

HALIFAX, NOVA SCOTIA--(Marketwire - June 30, 2011) - Erdene Resource Development Corp. ("Erdene") (TSX:ERD), is pleased to announce receipt of a National Instrument 43-101 compliant Technical Report ("the Report") for the Donkin Coal Project ("Donkin") in Eastern Canada. Marston & Marston, Inc. ("Marston") of St. Louis, Missouri, prepared the Report on behalf of Erdene and project manager Xstrata Coal Donkin Management Limited ("Xstrata"). Donkin is a joint venture between Xstrata Coal Donkin Limited (75%) and Erdene (25%).

The purpose of the Report is to present the results of the Pre-Feasibility Study ("PFS") on the Donkin Export Coking Coal Project prepared by Xstrata and the reserves defined by the PFS. The Report assesses the viability of a multiple continuous miner ("CM") underground operation, producing approximately 3.5 million tonnes per year ("Mtpa") Run of Mine ("ROM") coal that would be subsequently washed to provide 2.75 Mtpa of product coal suitable for the international export coking and thermal coal markets and domestic thermal coal markets. The Report confirms the technical and economic viability of the Donkin Export Coking Project and supports advancing the project to the next phase. The PFS concludes that Donkin has a $1.06 billion Net Present Value ("NPV") (8% discount rate) based on project development capital of approximately $500 million and demonstrates the potential for first quartile operating costs. The Report has been filed by Erdene on SEDAR and a copy of the PFS Report is also available on Erdene's website (www.erdene.com).

Coal Quality

The coal quality of the Harbour Seam is characterized by low ash, high energy, high vitrinite content, high fluidity, high crucible swell number ("CSN") and elevated levels of sulfur.

  • Low Ash - the expected level of 4% air-dried ("ad") is well below the typical range for hard coking coal of 7% to 10.5%.

  • Caking Properties - the average CSN of 8.5 places it within the range for premium hard coking coals of 8 to 9 CSN.

  • Plasticity - Donkin is a high fluidity coal, ranging from 10,000 to 25,000 dial divisions per minute ("ddpm"), with an expected maximum fluidity of greater than 10,000 ddpm. This characteristic enables its use as a coke blend component with lower fluidity coals.

  • Sulfur - the expected product sulfur content of 3% ad is above the typical range for hard coking coal which ranges to a maximum of 0.8% ad. However, this does not preclude the use of this coal in coking coal blends for the manufacturing of coke.

The Hub Seam metallurgical and thermal coal quality data is limited.

Subject to further coal testing, approximately 75% of product coal from Donkin is targeted to be marketed as a coking coal blend into international coking coal markets with the remaining 25% expected to be marketed to domestic and international thermal coal markets.

Mineral Resources and Reserves

The Report restates the coal resources for the Hub and Harbour Seams at Donkin with no change from previously reported resource estimates. The Report also classified a portion of the resources for the Hub and Harbour Seams as reserves. The Indicated Resources for the Hub and Harbour Seams are 73 million tonnes ("Mt") and 101 Mt respectively, for a total Indicated Resource of 174 Mt. Included in these resource numbers are 28 Mt and 30 Mt of Probable Reserves from the Hub and Harbour Seams, respectively, for a total of 58 Mt of Probable Reserves. The effective date for the resource and reserve estimates is May 2011.

Indicated Resources are those within the envelope of the offshore drill holes. Key parameters used in calculating resources included: Density of 1.3 g/cc; minimum 100 metres between seabed and coal seam; maximum depth below seafloor of 700 metres; 75 metre exclusion zone around drill holes; 150 metre exclusion zone around the Donkin Fault and no resources were estimated within 100 metres of the No. 20 mine for the Harbour Seam.

Key parameters used in calculating reserves included: Mining method is room-and-pillar mining with partial pillar extraction utilizing continuous miners; mine plans were limited to the Indicated Resource boundary; minimum overburden thickness of 175 to 200 metres; a 10% out of seam dilution was included; specific gravity of 1.45; 150 metre exclusion zone for the Donkin Fault (75 metres on either side) and 100 metre barrier surrounding drill holes; a 10% mining loss was included; and Salamon and squat pillar formulas were used for pillar design. Reserves are based on the assumption that the Harbour Seam coal and 50% of the Hub Seam coal are marketable as coking coal, and the other 50% of the Hub Seam coal is marketable as a thermal product.

As stated in the Report, there are no known environmental nor environmental permitting issues to which the estimate of mineral resources and mineral reserves may be materially affected except for the normal regulatory approvals presently being sought for Donkin. In addition, Erdene is unaware of any legal or political risks that could materially affect the potential development of the Donkin project.

There are sufficient Reserves at Donkin for the first 20 years of mining. These form the basis of the economic analysis. No Inferred tonnages are included in the economic analysis.

Project Plans

On June 28, 2011 a draft Project Description document was filed with Federal and Provincial regulators. This is the initial step in the Environmental assessment ("EA") process. The document seeks approval for the 2.75 Mtpa export coking coal project. The regulators will now review and provide comment prior to the final document being approved and filed as a public document. This final document and any alterations by regulators will guide the comprehensive environmental assessment study as well as the preparation of the feasibility study and the project design.

The feasibility stage will include the initial phase of mining, referred to as the exploration phase. The intent is to deploy one CM section in the Harbour Seam one year after securing an off-take agreement for the ROM coal. The exploration phase will provide the opportunity to collect multiple Harbour Seam bulk samples for testing the coal quality, geotechnical information on the roof, floor and coal, data on structures and gas desorption and underground drilling from the Harbour Seam will allow for collection of data for all categories within the Hub Seam. The additional geological and geotechnical information as well as the results of bulk sample testing by potential customers, will provide information necessary to finalize the mine and plant design and the ultimate production including an evaluation of the viability of a longwall. Included in this study would be continued work on the studies, plans, permits and licenses necessary to start construction and operate the mine. The Feasibility Study is estimated to cost $94.2 million and is forecast to be conducted over a 24-month period. The estimated cost includes tunnel rehabilitation, exploration mining along with the cost of the mining equipment and the study. The schedule for this initial development is dependent on securing a coal off-take agreement. Full development plans will be based on the outcome of the Feasibility Study.
