Non-executive director Craig Burton has sold 3m shares in Matra Petroleum at an average price of 4.16p a share but he still holds 45.2m shares - 4.53% of the Russia-focused oil and gas explorer. This follows last Friday's disposal of 18m shares by Macquarie Bank, which retains a 11.02% stake in Matra. Burton is a director of a number of quoted resources companies. Matra has started drilling the first appraisal well on on the Arkhangelovskoe License in Orenburg, Russia. There was a delay because of the lack of an interim generator but the site has been linked to the local electricity supply. The drilling will take around four months and cost $4.5m. Matra had €659,000 in the bank at the end of June 2009. Matra joined AIM in April 2006 following the reversal of Inke Petroleum into AIM-quoted Ming Resources. Matra sold its Hungarian interests in December 2008 in order to concetrate on its Russian exploration interests.
