Comments on the geologic information

LIMESTONE IN THE MINERALIZED AREA IS HIGHLY FRACTURED AND CONTAINS SOME GARNET AND OXIDIZED PYRITE, BUT NOT ENOUGH TO BE CONSIDERED A SKARN ASSEMBLAGE. GEOLOGIC MAPPING IN THE REGION INDICATES STRONG PROBABILITY THAT A LARAMIDE-AGE GRANITOID UNDERLIES THE LIMESTONE AT A DEPTH OF 50-100 M.
