Successful Trial Plantation


The Board of Caldwell is pleased to update shareholders on the progress of its
biodiesel feedstock project based in Brazil, as announced on 2 February 2007.

The project has taken a further tangible step forward with the successful
germination from mechanically planted seed of over 1,000 Jatropha tree saplings
at Caldwell's first trial plantation in Northern Brazil.

The purpose of the trial was to confirm that in the fertile conditions available
in Brazil, the Company is able to cultivate Jatropha trees directly from
mechanically planted seed without the need to invest in nursery facilities or
buy in more expensive saplings.

The Directors believe this successful trial confirms an important element of the
Company's project to cultivate Jatropha plantations in Brazil in order to
provide biodiesel feedstock for the European market.  The Board of Caldwell
emphasises that this project is still at a very early stage, requires further
due diligence and is subject to a number of major uncertainties, including
funding, recruitment of local management, access to suitable land and successful
cultivation of a large scale plantation


End.
