  • IN MEDICINE BOW NATIONAL FOREST. SIERRA MADRE MOUNTAINS
  • Bull. 50 says the Broadway mine is on Coon Creek., but it is on the East Fork of th Encampment River, about 2 mi. north of the confluence of Coon Ck. Unable to determine from the inset map fig. 70, p. 160 of Bull. 70 which shafts correspond to the shafts on the topo.
  • 13N is the correct township.

General comments

Subject category Comment text
Deposit DESCRIPTION OF DEPOSIT IS SCANTY BUT DISTRICT DESCRIPTION INDICATES THAT DEPOSITS SOUTH OF MULLEN CREEK-NASH FORK SHEAR ZONE ARE MOSTLY MASSIVE SULFIDES. ORES IN THIS DEPOSIT ARE FOUND IN AN IRREGULAR BODY ALONG THE CONTACT OF GRANITE AND GNEISSES WITH AMPHIBOLITES AND MAY SUGGEST A REPLACEMENT ORIGIN RATHER THAN A MASSIVE SULFIDE ORIGIN; UNPUBLISHED MODEL NAME: UNDETERMINED MASSIVE SULFIDE.
