Drilling Program
The deeper lignite seams within EL 4416, IER's wholly-owned exploration licence, that may not be mined economically, are prospective for huge amounts biogenic natural gas ('BNG'). A 9-well drilling program during 2007 and 2008 demonstrated the presence of permeable, gas-bearing lignite. Gas was produced to the surface (and flared), in sub-economic quantities, during an initial short-term test.
Independent Gas Assessment
The Company requested MHA Petroleum Consultants to provide an independent assessment and estimate of the Contingent and Prospective coal gas resource over EL 4416. MHA estimated that, given the current data available, the P50 Contingent Resource is 3.7 trillion cubic feet (“TcF”) of recoverable natural gas. See the table below for more detail.
| Estimate | Low (1C) | Best (2C) | High (3C) |
|---|---|---|---|
| Contingent | 0.66 Tcf | 3.7 TcF | 9.1 Tcf |
| Prospective | 0.23 Tcf | 1.3 TcF | 3.5 Tcf |
