The 2010 exploration programs are underway and are aimed at further testing and significantly expanding the current resources, as well drilling a large iron-rich basal conglomerate for the first time.
In the old Rio Algom drill logs, there was only a suggestion of this new Basal Conglomerate Bed and the potentially higher grades, but nothing close to the type of grades they're now seeing, said Shefsky.
The resources were found to lie in four prospective horizons: Szolnok, Lower Endrod, Basal Conglomerate, and Synrift Sequence.
Falcon was awarded a production license covering 245,775 net acres and an independent report, effective March 31, 2008, estimates potentially 42 trillion cubic feet of recoverable contingent resources for Falcon's interests in the Szolnok formation, the Lower Endrod, the Basal Conglomerate and the Synrift Sequence, and 98 million of barrels oil in the Upper Endrod formation.
We have flowed gas from both the Szolnok and Basal Conglomerate formations, proving the presence of the basin centered gas accumulation which was confirmed when the Hungarian Government awarded us a production license in May of this year.
Shefsky is very bullish about the their high-grade findings in a basal conglomerate bed 15 metres below a main conglomerate bed (sedimentary rock of pebbles solidified into solid rock).
Most probably, early diagenetic conditions were similar to the lithification stage of the basal conglomerate pebbles of the Upper Cambrian Kallavere Formation in the Pakri Peninsula (Nemliher & Puura 1996a).
The Browns Park Formation is divided into two distinct lithologies: a basal conglomerate member and overlying sandstone member, each of which host uranium deposits.
Falcon has resumed testing operations on the Mako-6 well in the lowermost part of the Basal Conglomerate, after fracture stimulating ("fracing") this interval in April 2007 with 79,000 pounds of proppant and 3,100 bbls of frac fluid.
All of the drillholes were pre-collared using a non-coring large diameter drilling rig to penetrate to the basal conglomerate layer of the younger Tertiary-age cover rocks which unconformably overlie the much older Paleozoic rocks.
