Environmental Impact Study Approval

On November 26, 2008, the Autoridad Nacional del Ambiente ("ANAM"), the environmental agency of the Government of the Republic of Panama, issued a Resolution approving the Company's Environmental Impact Study Category III (the "EIS"). The Resolution sets out a number of conditions to be satisfied before the Company can attain full commercial production of the Molejon Gold Mine in Panama. On detailed review of the Resolution, it became apparent that some of the conditions were not applicable to the Molejon operation, and others had already been satisfied by the Company. The Company therefore established a working group to cooperate with ANAM to ensure that all conditions are satisfied or waived, so that full commercial production in fiscal 2010 will take place without delay.

During the current period, the Company has been subject to regular inspections confirming its full compliance with the applicable environmental regulations. Petaquilla Gold, S.A., the Company's Panama subsidiary which operates the Molejon plant, has provided additional technical documentation on specific procedures related to the monitoring of the environmental impact on water, soil and air as well as various studies on health and migration of populations within the area of influence of the mine project, fully complying with the conditions defined by ANAM for readiness for commercial production. Accordingly, the Company expects to initiate full production as soon as the technical pre-production testing is completed which is expected to occur at or about the same time as approval from the Ministry of Industry and Commerce is obtained.

Several meetings have been held with ANAM personnel and ANAM's appointed independent ITS Consulting and EnviroLAB Laboratories to establish a routine of regular environmental inspections.

The Company has retained SGS Panama Control Services Inc., part of the Swiss group SGS - Societe Generale de Surveillance, for the process of certification to the international standards on Environmental Management, ISO 14001 and Safety and Occupational Health, OHSAS 18001.

Mill Commissioning and Production

The Company announced wet commissioning on November 28th, 2008, after initiating a pre-production test program; progressively bringing online some of the critical process equipment. During the third quarter, 18,000 tons of low grade ore were used to test the "mine to plant" feed circuitry. Such tests met the requirements of a technical covenant related to the senior secured note financing. This test material did not result in a gold pour.

The Company produced its first gold bar on April 7, 2009.
