New Optimized Zaruma Plant Design Increases Gold Recovery To 92% - Dynasty Hires Zaruma Mine Manager
July 18th, 2007
Vancouver, BC, July 18, 2007 - Dynasty Metals & Mining Inc. (TSXV:DMM, the “Company”) has received confirmation that Keith C. Dodd Consulting Engineers (“Dodd”), of Perth, Western Australia, has completed the design optimization of the Zaruma Gold Project processing plant.
In an update report, Dodd has advised the Company that “the favourable mineralogy of the resource has resulted in a compact plant with high flexibility and a significantly higher recovery than was initially expected.”
Separately, Bill Blake, a mining engineer with 26 years of experience, has joined the Company as Mine Manager of the proposed Zaruma gold mine. In that capacity, he will have primary responsibility for mine operations.
Zaruma Plant Design Update
Dodd’s update report to the Company advises that, as a result of process design improvements suggested by laboratory and metallurgical testwork, overall gold recovery across the entire Zaruma plant is expected to increase from 87%, previously estimated to yield annual gold production of approximately 100,000 ounces, to more than 92%.
Independent Metallurgical Laboratories Pty Ltd (“IML”), also based in Perth, conducted all laboratory and metallurgical testwork on which the Dodd design work is based. The testwork showed that the introduction of a flotation circuit after the secondary mill discharge cyclone achieved a 50% higher gold recovery than that achieved using a gravity separator, and reduced the mass flow to the leach circuit by 85%.
As a result, the size of the proposed leach plant has been reduced to one tenth of that originally envisaged - thereby reducing the overall size of the plant and budgeted capital expenditures.
Zaruma Construction Update
Work continues on the main decline at the Ana Michele (Cabo de Hornos) site. The four metre by four metre portal is finished and reinforced by earthworks. An adjacent pad has been completed to position the future mine compressor and substation and for decline access to the new underground workings.
The ground in the decline appears to be competent and predictable and should permit the rapid and safe advancement of the decline.
In other developments at Zaruma:
- The explosives magazine at the Barbasco decline site has been completed on schedule and has received the required official certification.
- The small Zaruma pilot plant is working to specification, processing an average of 20 tonnes of ore per day.
- In addition to equipment already on the Barbasco site (as announced June 12, 2007), two Jumbo underground drills are expected in two weeks, with further equipment to arrive as mining operations expand.
- In a visit to the Zaruma mill site at the end of June, Dodd established the site positioning of the proposed crushing, milling and security facilities.
- The latest equipment arrivals for the Zaruma plant include another Harding ball mill and the jaw crusher for the secondary crushing circuit.
Bill Blake is an Australian with 26 years of experience in mining. He has held positions at mines worldwide as mine manager, underground manager, foreman, and seventeen years as underground shift supervisor. Progressing through the ranks, he has operated virtually every type of mining equipment, with experience ranging from large-scale bulk mining to years in narrow-vein mining.
Mr. Blake has had extensive experience training local mine staff in mines in Indonesia, Ghana, and Western Australia. In assuming the position of Mine Manager at Zaruma, he will be responsible for establishing and maintaining a world-class standard of operations, not previously seen in Ecuador.
About the Zaruma Gold Project
The Zaruma Gold Project is located in the cantons of Zaruma and Portovelo, Province of El Oro, Ecuador, approximately 160 kilometres south of Guayaquil, Ecuador’s main seaport. The project comprises 44 mineral concessions, covering approximately 103 square kilometres, in an active high-grade goldfield. Gold mineralization occurs in a 15 kilometre by 5 kilometre polymetallic epithermal precious metal vein system.
An Independent Preliminary Assessment of the Zaruma project, announced by the Company on July 12, 2006, estimated a pre-tax undiscounted cash flow of US$467 million over a 14.5 year mine life from annual production of approximately 100,000 ounces of gold. The Company expects to commence production at Zaruma in the first quarter of 2008.
