Vecta Project (90% interest in Billy
Goat, 20% working interest in other areas)
The Vecta Project is operated by
Vecta and is located in Las Animas County, close to the Red Rocks
helium producing field, and Blue Star Helium's Galactica
development project. Helium concentrations of up to 11% have been
encountered in offset wells and fields in the area, with the
closest well, Texaco Cynthia True-1, flowing 8.8% helium from the
upper Lyons sandstone.
A total of five wells are planned to
be drilled in this drilling campaign, testing five individual
structural closures.

Andy Carroll, Chief Executive Officer of Mosman,
said: "The drilling of this Billy
Goat well is exciting given the excellent lease position in a
proven area of helium development and production
"Each well location has been
carefully selected by the very experienced team at Vecta and we
believe each well has an excellent chance of discovering helium.
The low-cost drilling of these wells enables data to be obtained at
very reasonable cost.
"This location has good access to
infrastructure including roads, pipelines and the Ladder Creek
helium plant located at Cheyenne Wells, about 100 miles north of
Billy Goat."
