Item 8.01 Other Events

To date, due to general financial market conditions and, more specifically, to falling market pricing for metallurgical coal in Colombia and in other global markets, we have been unable to secure additional funding to implement our current business plan. In response, Management has elected to reduce operations and sell non-essential assets to preserve remaining funds until such time as additional funding can be obtained. These cost-cutting actions include reducing administrative staff in our Bogota office. Until metallurgical coal prices rebound or additional working capital is obtained, we have reduced mining operations at our Ruku mine and are currently producing and selling minimal tons per month. In addition, because of a lack of funding and lack of visibility on future metallurgical coal pricing in Colombia, we did not exercise our option to acquire the Boavita concession FFB-081 under our agreement with AMERALEX, although our association agreement permitting us to conduct production activities on the property remains in force. We have also termination our agreement for the North Block concession FLG-092. Management has elected to focus our near-term operations on our Ruku and Otanche concessions. In addition to seeking new investment capital we are engaged in discussions with potential strategic operating partners, potential customers seeking off-take agreements, and potential acquirers of the concessions.
