June 25, 2010 Newcastle Minerals announced that it has, subject to regulatory acceptance, agreed to sell its interest in 25 load quartz mineral claims located in Yukon Territory to First Lithium Resources.
November 16, 2009 Newcastle Minerals Ltd. completed an airborne geophysical survey on its 25 quartz mineral claims located approximately 15 kilometres east of Underworld Resources’ White Gold property in Yukon Territory, Canada. The low-level multi-sensor airborne survey, which comprised 65 line kilometres flown at 100-metre spacings, collected data from magnetic and radiometric instruments. Interpretation of the results are to be released when available. In its June 24, 2009 press release, the company reported that its claims covered approximately 1,000 hectares. Management has confirmed, however, that its 25 claims actually cover 522.5 hectares.
