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."
