Dalradian Resources Reports Positive Preliminary Economic Assessment for the Curraghinalt Gold Project in Northern Ireland

TORONTO, ONTARIO--(Marketwire - July 25, 2012) - Dalradian Resources Inc. (TSX:DNA), is pleased to report positive results from the Preliminary Economic Assessment ("PEA") for a proposed underground mine at its wholly owned Curraghinalt Gold Deposit in County Tyrone, Northern Ireland. The PEA study was led by Micon International Limited ("Micon"), with contributions from other independent consultants. All figures are quoted in US dollars except where otherwise noted.

Highlights of the PEA:

  • Pre-tax Internal Rate of Return ("IRR") of 51.7% (after-tax 41.9%) based on a 36-month trailing average gold price of $1,378 per ounce (after-tax IRR of 31.8% based on $1,200 gold price);
  • Project payback of 2 years from first gold production;
  • After-tax Net Present Value ("NPV") of $467 million based on a 8% discount rate and a realized gold price of $1,378 per ounce ($655 million using a 5% discount rate);
  • Initial capital expenditures of approximately $192 million prior to production start-up (including contingencies of $36.9 million), with sustaining capital of $110 million for a total Life of Mine ("LOM") capital spend of $302 million;
  • A 15 year mine life with average LOM cash operating costs of US$532 per ounce, or $125 per tonne milled, including royalties, refining costs and by-product credits of $8.24/oz gold;
  • LOM gold production of 2.223 million ounces;
  • Average mined grade of 8.1 g/t gold. Processing at a rate of 1,700 tonnes per day and producing approximately 145,000 ounces gold per year using a conventional flowsheet of crushing, grinding, cyanidation and conventional tailings disposal;
  • Underground mining using mechanized longhole methods with ramp access and truck haulage; and,
  • The mine plan considers 89% of the November 2011 Micon resource estimate, of which 83% is inferred.

Chairman and Chief Executive Officer, Patrick F. N. Anderson says, "Our first economic study on this portion of the Curraghinalt deposit has been a resounding success. Our next steps are to: better understand the existing resource, prove, through drilling, that the system has a lot of room to grow and move ahead with planning and permitting for underground development. We have people and drills on the ground right now working towards these goals."

The PEA is preliminary in nature. It includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the results of the PEA will be realized.

Mineral Resources:

The basis for the PEA is the mineral resource estimate prepared by Micon in the NI 43-101 report dated January 10, 2011 and effective November 30, 2011 entitled "An updated Mineral Resource Estimate for the Curraghinalt Gold Deposit, Tyrone Project, County Tyrone and County Londonderry, Northern Ireland", which was filed on SEDAR on January 13, 2012.

A summary of this resource (reported at a cut off grade of 5.0 g/t Au diluted to a 1 m minimum horizontal width) is:

Resource Category Mineral Resources
(as at November 30, 2011)
Million Tonnes Grade (g/t gold) Contained Metal
Tonnes M oz
Measured 0.02 21.51 0.44 0.01
Indicated 1.11 12.84 14.20 0.46
Measured + Indicated 1.13 13.00 14.65 0.47
Inferred 5.45 12.74 69.44 2.23

Note: Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Mine Plan:

The mine plan developed by Micon uses mechanized longhole mining with ramp access and truck haulage, at a production rate of 1,700 tpd. Ramp access was chosen over shaft access due to the long lateral extent and relatively shallow depths of the deposit. As the deposit is open at depth a shaft may be required in future to access levels below the current mine plan. The mine plan includes provisions for mining losses and dilution. The mine plan is inclusive of inferred resources. These inferred resources will require further exploration drilling to upgrade them to the higher measured and indicated categories.

Processing and Metallurgy:

The processing flow sheet selected for the PEA consists of crushing, grinding, cyanidation and conventional tailings disposal. This flow sheet is based on extensive metallurgical testing carried out by previous operators of the project, and by Dalradian. Several other processing flow sheets were examined in the PEA, but were determined to result in less favourable economic outcomes. Total gold recoveries, based on existing metallurgical test work, are expected to be approximately 92%.

Operating Costs:

Operating Costs US$/tonne mined
Mining costs $ 76.50
Processing costs $ 19.41
General & Administrative costs $ 8.30
Direct Operating Costs before Royalty $ 104.21

Capital Costs:

Initial capital expenditures total approximately $192 million, inclusive of a $37 million contingency. LOM sustaining capital totals approximately $110 million. Sustaining capital consists of capitalized waste development after the initial production start-up, major equipment replacement and tailings expansions. Mining sub-level development cost is included in the operating cost.
