Drilling is progressing rapidly following several days of slow

Drilling is progressing rapidly following several days of slow timed drilling through arkosic sandstone formation. Following a change over to a tricone bit early this morning, drilling passed from the arkosic sandstone into an interbedded siltstone/sandstone sequence. This transition corresponds to the western boundary of the low velocity zone identified from the 2005 drilling logs.
