Production and reserves

Workings or exploration Placer claims worked for several years between 1898 and most recently in 1938. Most claims proved to be disappointing. In 1915, a tunnel was driven 144 ft in slate to tap an old channel about 8 miles above Bird Creek mouth. Prospector was not successful (Capps, 1916). An aplite sample from a lode claim in 1898 assayed 0.36 oz/ton Au (Mendenhall, 1900).
Indication of production Yes; small
