Work History
Staked as Green Eagle cl (Y38608) in Oct/69 by J.B. O'Neill on a geochemical anomaly and optioned to a private syndicate which allowed the claims to lapse. Restaked by O'Neill as Green Eagle cl (Y59265) in Oct/70 and optioned to A.E. Hooper, who formed a new company, Charta ML, to develop the property. Charta completed limited hand trenching in 1970 and a mapping, soil sampling and geophysical program in 1971.
Restaked as Dent cl (YA48219) in Sep/79 by R.C. Hilker.
Capsule Geology
Claims cover a prominent gossan associated with a pyritic envelope around a young stock which intrudes older granodiorite. The younger pluton is composed of quartz porphyry, granite porphyry, feldspar porphyry and aplite that has been strongly fractured. Quartz veining is not common and hydrothermal alteration is very weak.
O'Neill obtained moderate geochemical response in copper and lead but only minor amounts of disseminated chalcopyrite and molybdenite. Galena and arsenopyrite occur in quartz veinlets. Surface leaching is minimal.
