Speaking at the official opening, Catalpa Managing Director Bruce McFadzean said the successful Edna May Gold Project had been achieved, not in isolation, but with the consent, support and tremendous effort of a great number of people, including the very supportive community of Westonia.

“The relationship between Catalpa and the community is a two-way street,” Mr McFadzean said.

“From the outset, Catalpa made a commitment to spending its money where its mine is. We are proud to say that the majority of the $92 million project was spent in WA, and, wherever we can, we source our goods and services from Westonia and surrounding communities.

“In the months leading up to the project start, we took our recruitment drive to the country roads throughout the Wheatbelt, and as a result have successfully recruited approximately 50% of our workforce from within driveable distance of the mine.”

Mr McFadzean flagged further growth aspirations for Catalpa going forward: “With a continued strong outlook for gold, and the exceptional forward sold gold price of $1,557 achieved for some 352 000 ounces of Edna May’s production, this project is set to deliver a strong revenue stream.

ABOUT CATALPA

Catalpa Resources Limited (ASX: CAH) has two exciting gold assets; a 30% interest in the 100,000 ounce per annum Cracow Gold Project - a producing gold mine in Queensland (70% Newcrest Mining Limited); and the 100,000 ounce per annum Edna May Gold Project in Western Australia (100%) – an operating mine currently ramping up to full production.

The A$92 million Edna May Gold Project is fully funded, and, as part of the finance facility, Catalpa has sold forward 352,316 ounces of gold at A$1,557.50 per ounce. At an average gold price of A$1,400 per ounce Catalpa will realize an average cash operating margin of A$72 million per annum from the Edna May Gold Project alone.

With a combined Mineral Resource of more than 1.9 million ounces and a combined Ore Reserve of more than 1.0 million ounces of gold (refer announcement dated 27[th] May 2010), the Cracow and Edna May will provide a sustainable cash flow to fund Catalpa’s growth strategy.

Catalpa is confident that both Cracow and Edna May offer further Reserve and Resource growth potential, with ongoing exploration programs at both operations. In parallel, the Company continues to proactively identify and assess other production growth opportunities.

The Company has a committed and technically accomplished management team and a highly experienced and supportive Board, committed to realising shareholder value from the Company’s growing asset portfolio.

Catalpa has adopted best practice standards across all its activities, including health and safety, environmental management, corporate governance and social responsibility.

EDNA MAY OPERATIONS (100%)

Catalpa’s wholly-owned Edna May Gold Project is conveniently positioned just two kilometers from the infrastructure of Westonia, on the eastern edge of WA’s Wheatbelt region. The mine is half way between Perth and Kalgoorlie and ideally situated to be serviced by either of these major mining centres.

With its robust economics, geologically and metallurgically well defined ore-body, high Ore Reserve confidence and excellent recovery rate of more than 92%, Catalpa’s Edna May Gold Project offers an attractive, long-term platform to grow a mid tier gold producer.

Catalpa’s mine and processing schedule demonstrate average gold production at Edna May in excess of 100,000 ounces of gold recovered per annum for a life of mine of more than nine years, with first gold production achieved in April 2010.

CRACOW GOLD OPERATIONS (30%)

Catalpa owns 30% of the Cracow Gold Project in Queensland with Newcrest Mining Limited, and also has a preemptive right over Newcrest’s 70% stake in the asset. The Cracow Gold Project is well managed and operated by Newcrest, allowing Catalpa to remain focused on the Edna May Gold Project.

The Cracow Gold Project has a history of steady gold production of over 100,000 ounces per annum for the past four years and it is considered to have considerable exploration upside.
