BAKERSFIELD, Calif., Aug. 2 /PRNewswire-FirstCall/ -- Select Resources Corporation and Curlew Lake Resources jointly announced today initiation of the 2005 exploration program of their jointly held Typhoon claim group in the Clear Creek District of Yukon Territory. The program is designed to identify lode gold deposits in this historic placer district. The first phase of the program is to complete a detailed soil geochemical survey and a ground magnetometer survey of the claim group, focusing on claims staked in 2004. This program will include follow-up of several soil anomalies identified late last year. It is expected that soil samples will be submitted for analysis within the next few days, with preliminary results expected in approximately 30 days. As announced earlier, Select has optioned Curlew Lake's Typhoon claim group in the Clear Creek District, consisting of approximately 3 square miles of claims. The Clear Creek District is recognized as a component of the Tintina Gold Province, which hosts a number of significant lode gold deposits in Alaska and Yukon Territory. The Typhoon claim group extends for several kilometers along 65 Pup Creek, which shows evidence of placer mining. Harold Noyes, Select's President, stated, "This is an exciting opportunity for Select to extend its experience in the Alaska segment of the Tintina Gold Province to another promising area. The geologic environment, the evidence of bedrock occurrences, and the extensive placer workings are all positive indicators of potential mineralization in the Clear Creek District."
