After geologic research spanning a period of about four months, in the fall of 2003 we initiated an aggressive program of ground acquisition. We have Federal lode mining claims, in numerous separate blocks covering breccia pipe targets located on the Colorado Plateau Province of Northern Arizona known as the Arizona Strip. This major project is known as the North Pipes Super Project, and is targeted specifically for high-grade uranium mineralization.
Jim Briscoe,CEO, Chief Geologist and Chairman of the Board, developed uranium exploration experience from 1978 through 1980 when his consulting company was under contract with the exploration subsidiary of the largest nuclear electric utility in the U.S.A. His company had responsibility for uranium exploration over the entire state of New Mexico. Based on this experience, he started a thorough research program in late 2003 to determine the prospects of exploration on the Colorado Plateau. Using a multifaceted approach, Liberty Star geologists, along with the help of a very talented geologic expert particularly familiar with these breccia pipes identified the breccia pipe targets that we have staked starting in the fall of 2004.
According to the U.S. Geological Survey, the breccia pipes in this region are of high grade compared to sediment hosted roll front deposits mined throughout the western US, with an estimated potential average grade for ore bearing pipes at about 0.7% to 0.8% uranium. This suggests that such pipes may contain mineral bodies of about 14 to 16 pounds or more of uranium per ton. The pipes contain numerous metals in addition to uranium including copper, silver, vanadium, molybdenum, cobalt and nickel. The uranium mineralization however is by far the most economically important. Mines in this region have produced some 26 million pounds of uranium; some of these known ore bodies have contained as much as 55% uranium (1100 pounds per ton) in some samples.
Exploration at North Pipes is for high-grade uranium ore bodies that can be mined economically by underground methods. This area can be explored during the winter months by the Liberty Star exploration team.

Nearly all primary ore confined to the breccia pipe: rarely, a little uranium ore is reported in relatively undisturbed beds outside the ring structure. Vertically, most primary ore is below the Coconino Sandstone and at the level of the Hermit Shale and the Esplanade Sandstone of the Supai Group.
