CPO-5 (WI 30%): Exploration Drilling Update

Logging operations on the Sol-1 exploration well on Block CPO5 (AMER 30%) are now complete. The well was drilled to a final depth of 9,986ft. Following initial analysis, 26.5ft net oil pay in the LS3 and 10.5ft net oil pay in the LS1 sands of the Une formation were identified, based on logging and MDT samples. Short term testing operations are now underway and the company will provide a further update once this is concluded.

After testing operations are completed at Sol-1 the rig will move to drill the Indico-2 appraisal well.

John Wardle, CEO of Amerisur Resources said:

"We are pleased to report that Sol has encountered potential net oil pay. Although smaller than the oil column encountered by our previous discoveries it demonstrates the potential for further prospectivity across CPO-5".
