Otter Lake Acquires Major Mineral Properties in Colorado with a Total of 238 Claims

San Diego, California, June 22, 2007 - Otter Lake Resources Inc. (PINKSHEETS: OTLK) is pleased to announce the acquisition of 238 mineral claims adjacent to the Baboon Basin area of Montrose County, Colorado. These new properties are all located in areas surrounding the Baboon Basin area, which has significant existing uranium- vanadium ore reserves. This acquisition expands Otter Lake's property ownership and gives the Company the ability to aggressively increase its resource base. According to Martin Ermer, President of Otter Lake Resources, "We are very excited about this latest acquisition. Approximately 175 test drill holes have been drilled in the Baboon Basin area, and Thamm, Mickle and Co., a geologic research company located in Grand Junction, Colorado, concluded that positive, indicated, and inferred geologic ore reserves are present in as many as 6 separate zones within the ore body. Since our properties are adjacent to the Baboon Basin, we fully expect to see similar results from our properties." About Otter Lake Resources Inc.
