Comments on the geologic information

  • Geologic Description = The Suds prospect consists of a gossan that contains sphalerite and galena (I.F. Ellersieck, written communication, 1979). The deposit is in the Mississippian Lisburne Formation of black shale and chert, and the geologic setting is similar to that at the Red Dog and Lik deposits (ARDF numbers DL001 and DL005).? Cominco drilled the property in 1999 and announced significant lead-zinc mineralization at depth in three drill holes. The first intersection is 53 feet of 30% Zn and 6% Pb at a depth of 2,227 feet. The second intersection is 20 feet of 15% Zn and 5% Pb at a depth of 2,182 feet. The remaining intersection is 160 feet of 18% Zn and 5% Pb at a depth of 2,299 feet. The mineral deposit is flat-lying and open to the north, west, and south. (Business News Alaska Staff,1999).
  • Age = Mississippian.
