ENVIRONMENTAL MINING APPROVAL NOTIFICATION FOR EDNA MAY OPERATIONS

Catalpa Resources (ASX: CAH), the Perth-based emerging gold producer today announced Environmental Mining Approval had been recommended subject to the lodgement of bonds for its fully-funded Edna May Gold Operations in Westonia, Western Australia.

Catalpa Resources’ Managing Director, Bruce McFadzean confirmed the Company received the Approval notification on 25 May 2009 and commented: “The Mining Approval was one of the final outstanding conditions precedent for Board approval to advance the Edna May Gold Project to production.

“We have already commenced detailed engineering and placed orders for the village and other equipment, however with the Approval now in place, we will now formally ‘kick-start’ Edna May’s 12-month construction and commissioning phase without further delay, to meet our target of first gold production by mid 2010.

“We have made considerable progress on the project design and planning in recent months, including provisional appointment of our major contractors. We are now in a position to finalise these appointments and expedite the construction and commissioning of the accommodation village ahead of the imminent on-site construction activities.”

Regional Job Creation

Mr McFadzean confirmed Catalpa’s Edna May Operations will create more than 180 direct site jobs at peak construction and more than 110 full-time jobs during normal production.

“We’ve been conducting a series of public meetings in the communities surrounding Westonia, so initially we hope to attract more than 30% of our workforce locally, with a target to increase the local workforce component to at least 50% by mid 2010 when we settle down into normal production.

“We are delighted to be in a position to move the Edna May Gold Project forward. Our confidence in this project was well-placed, and we remain confident that the project’s sound economics will provide a strong platform to fund Catalpa’s growth and achieve our vision of becoming Australia’s next mid-tier gold company.”
