Comments on the geologic information

  • Geologic Description = The Alvinella prospect is in the southern part of a several-square-mile area which contains five surface showings of lead and zinc mineralization in the black shales of the Mississippian Lisburne Formation. The geologic and structural setting is similar to that at Red Dog (ARDF number DL001). Thrust faults cause repetition of the mineralized shale horizon. The thrust blocks overlie the Cretaceous Wolverine Creek allochthon, which is the structural footwall of the Red Dog sequence. Drilling at the prospect has intercepted zones of low-grade mineralization. The prospect is named for fossilized worm tubes commonly found in the Ikalikrok Member, which consists of silicified, sulfide-bearing shale, carbonate, and non-silicified shales. The tubes are associated with at least minor base-metal sulfides and are thought to indicate sites of hydrothermal discharge (Young, 1989).
  • Age = Mississippian.

Economic information about the deposit and operations

Development status Prospect

Comments on exploration

  • Status = Active

Mining district

District name Lisburne

Comments on the workings information

  • Workings / Exploration = The general area has been mapped, sampled, and explored by geophysical surveys. Several core holes, drilled since the early 1980's, have intercepted thin, low-grade mineralization (Scott Jennings, oral communication, 1999).
