Results of the first Edgeroi corehole, which we reported on last week, are additional confirmation of the significant coalbed methane potential of our PEL 238 license area.
The Edgeroi-1 corehole was drilled approximately 26 miles north of the existing Bibbliwindi and Dewhurst areas and intersected a total of more than 70 feet of coal, including 33 feet of coal within the primary targeted Bohena coal seam.
The early results of our corehole pilot program have been very encouraging, and we are looking forward to getting the multi-lateral production program underway in September.
In Australia, the results of the Dewhurst #2 corehole ultimately could have a significant impact on the value of Gastar since this well confirms a thick, continuous coal seam within a small portion of our license area that, with additional successful development activity, could allow our joint venture to book proved and probable reserves sufficient to meet the volume requirements under one of our approximate 500 BCF MOU's with New South Wales power generators.
Gastar and our joint venture partner, Eastern Star Gas, are currently finalizing plans for a work program to be carried out during 2008 that is expected to include an expanded corehole program and the drilling of additional coal seam gas production pilots.
Our ongoing nine-well pilot program is continuing to perform well, and we are currently drilling a six-well corehole program designed to increase 2P reserve certification by mid-2008.
Southern Pacific expects to use the net proceeds of this offering for the long lead equipment orders and engineering on the STP-McKay Phase 1 Expansion, to improve its working capital position, for working capital required to manage the recently announced rail marketing arrangement and for a discretionary corehole exploration program over the winter of 2012/13.
Patch stated that as many as six drill rigs were being added to complete its combined 28 corehole program.
The South Crater also has other pyroclastic kimberlite (OPK) units of limited areal extent including OPK-13, a different kimberlite type identified only in corehole 04-122-013.
Most of the stones were recovered from a large amount of sample taken from the centrally located corehole 04-221-003 that was targeted on the eruptive vent and near to historic drillhole 221-001 drilled in 1996 using a conventional circulation rotary drilling method.
