Leni Spuds Spanish Hontomin Well

Leni announced the commencement of the drilling activity and the spudding of the hole for the Hontomin extended well test in northern on-shore Spain.

The objective of the Hontomin program is to appraise the long term production potential of the Hontomin-2 well.

Electric wireline logging and perforation of the existing hydrocarbon intervals and other potential undepleted zones is scheduled for September/October 2010 to assess the full production potential of the structure.

All well production from Hontomin will be transported to the central production facilities at the Ayoluengo operations base for processing and oil sales.
