1927: J. Brett and D. Duffy discovered spectacular coarse grained native gold (Gledhill 1929). The Brett-Tretheway Mining Co. was formed (Rogers and Young 1928), a vertical 125 foot deep shaft was sunk, and about 100 feet of crosscutting was completed. About $3,000 worth of gold (about 145 ounces) is reported to have been mined. 1928: Brett-Tretheway Mining completed 8,590 feet of trenching and pitting (Sinclair et al. 1930). 1929: Operations were suspended (Kindle 1936). 1944: F.L. Cooper sampled quartz veins. 1946: A Mr. Caswell diamond drilled 1 hole which yielded anomalously auriferous material (a core length of 3 feet averaged 0.20 ounce of gold per ton). 1975: R. Bugow trenched near the shaft. 1979: J.P. Larche completed a VLF electromagnetic survey. 1986: F. Kiernicki and M.
