BOTSWANA STOCK EXCHANGE LISTING

Perth-based integrated energy company Aviva Corporation Limited (ASX:AVA) has expanded its international presence by today successfully listing on the Botswana Stock Exchange (BSE).

Aviva joins a growing list of international resource companies who have obtained a secondary listing on the BSE.

Aviva Chief Executive Officer Lindsay Reed said the BSE listing was further evidence of the company’s ongoing commitment and expansion in Botswana, where it is rapidly advancing its 1500MW Mmamantswe integrated energy project.

The BSE is the third largest financial exchange in Africa, with more than $US5 billion of domestic funds under its management.

“We are pleased to have completed our successful listing on the Botswana Stock Exchange. We are continuing to make rapid progress at Mmamantswe and look forward to developing a significant shareholder base in Botswana which will benefit all Aviva shareholders,” Mr Reed said.

During the quarter Aviva completed an orientation drill program at the coal deposit that will fuel the Mmamantswe energy project . In total, 32 holes have been drilled for approximately 3,500 metres. The coal intercepts logged support the initial target of 600 million tonnes.

Aviva expects to announce a resource estimate for the deposit by the end of the December quarter.
