Actual locations drilled and quantities that may be ultimately recovered from our concessions will differ substantially. Ultimate recoveries will be dependent upon numerous factors including actual encountered geological conditions and the impact of future oil and gas pricing.   This presentation may also include certain non-IFRS (International Financial Reporting Standards) financial measures which have not been subject to a financial audit for any period.
