Work History
The west (Esperanza) occurrence was staked as Primrose, etc cl (5478) in January, 1902 by J.C. Lloyd, who drove two short adits (4.6 m and 7.6 m) later in the year. J.J. Flanagan staked Emerald, etc cl (5702) on the east (Raven) occurrence in April,1902 and drove a 9.1 m adit in 1903. The Primrose cl was re-staked as Kelvin cl (7309) in August, 1906 by A. McKinnon, who trenched in 1907 and as Esperanza cl (12194) in December, 1911 by C. Fothergill, who drove a 7.3 m adit in 1912. Fothergill re-staked the Emerald cl as Raven cl (12120) in June, 1911 and drove a 22.9 m adit in 1912.
Re-staked as Spike cl 1-24 (YA10268) in June, 1977 by Riocanex Incorporated, which explored with geochemical sampling later in the year and with geophysical surveys in 1978. W.G. Grant staked RA cl 1-20 (YB84648) two km to the south in October, 1984 and trenched in 1985. Gold City Resources Ltd staked Ann cl 1-2 (YB17660) 1 km to the west in August, 1988.
Capsule Geology
At both occurrences, adits were driven on pyritic quartz lenses concordant with the foliation in a sericite-quartz facies of the Klondike Schist. In the Raven adit, chalcopyrite is disseminated with pyrite on cleavage planes. MacLean's samples all assayed trace in gold and silver, but were not assayed for copper. The Riocanex work returned no anomalous values.
