ASX AND MEDIA ANNOUNCEMENT

BOTSWANA PROSPECTING LICENSE GRANTED

Aviva Corporation Limited (ASX:AVA) is pleased to advise that the Mmamantswe Prospecting License, positioned between the major infrastructure corridor of Botswana and the South African border, has been granted.

Joint Venture partner, Mawana Minerals (Pty) Ltd (Mawana), has advised the original application area has been extended to the South African border and two adjoining tenements, (Prospecting License Numbers 069-070/2007) covering 1830 square kilometres have been granted.

Aviva has already commenced field reconnaissance and successfully located exploration drilling conducted by BP Coal. A drilling program is planned to commence in the June 2007 quarter.

The Mmamantswe Coal Project tenement area is close to existing infrastructure. Rail, power and highway links to Gabarone and South Africa pass within 30km of the coal deposit.

The Botswana Department of Geological Survey has published an inventory of 598Mt of coal within the tenement and puts the potential of the area at more than two billion tonnes. Aviva believes a target of 600 million tonnes is realistic.

Aviva and Mawana have entered into an agreement whereby Aviva will spend $US0.5M over 18 months upon which Mawana will grant it an option to earn a 90% Joint Venture interest in the project by completing a Bankable Feasibility Study.
