Exploration and site history

• History: A radioactive anomaly was detected from the air by prospectors during the 1950's. Shallow prospect pits, trenches, and one diamond-drill hole revealed mineralized material. One sample was reported to contain 0.20% eU (equivalent uranium), but a commercial deposit was not indicated. (Eakins (1975))
• Site: The Lucky Six Claim Group, hereafter referred to as Lucky Six claims, is located on the west side of Lynn Canal, approximately 42 miles northwest of Juneau (figs. 1, 4). These claims lie between 1,500 and 2,000 feet above sea level on a ridge 1-1/2 miles south of Endicott River and 2 miles north of the mouth of William Henry Bay. It is a steep, difficult climb on foot from the coast. But above 1,500 feet, the claims are mostly above timber line and the bedrock is exposed in many places. (Eakins (1975))
• Exploration — Intermittently explored; several diamond-drill holes along with surface pits, trenches, and surface sampling, 1960–1989 (Clough and Redman (1989))
• Discovery — Radioactive anomaly detected from the air by prospectors, 1955–1959 (Clough and Redman (1989))
