(“Liberty or the Corporation”) is pleased to announce drill results from ongoing definition drilling at Liberty’s McWatters nickel (“Ni”) deposit. A combination of exploration and definition diamond drilling from surface has been designed to accurately identify the ore zone for mining, scheduled to commence later this year. The core lengths presented in the following table are the intersected core lengths, and the composite lengths are core weighted. These do not necessarily represent the true width of the ore body.

MCW-07-65 and MCW-07-66 have expanded the mineralized zone by approximately 10m to the north. “These results are very encouraging,” said Liberty’s Vice President of Exploration, William Randall. “We did not expect to expand the deposit to this extent, and will continue to systematically investigate every section for similar mineralized zones,” he added. The project was supervised by Liberty’s Vice President of Exploration, William Randall MSc (Geology), and by Richard Allard P. Geo, a qualified person as defined by National Instrument 43-101. According to the company sampling protocol, half of the diamond drill core is sampled and sent to ALS CHEMEX in Timmins to be prepared for analysis. The prepared samples are then forwarded to the ALS CHEMEX Laboratory in Vancouver for analysis. Base metal values are analyzed by aqua regia digestion and ICP-AES finish. A rigorous QA/QC program is implemented consisting of regular insertion of standards and blanks to ensure laboratory integrity About Liberty Mines Inc.
