Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Environmental Factors): ONE DISCHARGING ADIT WAS IDENTIFIED AT THE SITE DURING THE INVESTIGATION. MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED FOR CADMIUM AND ANTIMONY IN THE ADIT DISCHARGE. THE PH MEASUREMENT IN THE ADIT DISCHARGE WAS 6.10 AND THE SPECIFIC CONDUCTANCE WAS 980 UMHOS/CM. THE INTERMITTENT MCKAY GULCH WAS FLOWING DIRECTLY THROUGH THE SITE (THROUGH THE WASTE ROCK DUMPS IN PLACES). OBSERVED RELEASES TO MCKAY GULCH WERE DOCUMENTED FOR ARSENIC, CADMIUM, IRON, MANGANESE, LEAD, AND ZINC. THE MAXIMUM CONTAMINANT LEVEL FOR CADMIUM WAS EXCEEDED IN THE DOWNSTREAM MCKAY GULCH SAMPLE AND WAS DIRECTLY ATTRIBUTABLE TO THE SITE. MATERIAL TENTATIVELY IDENTIFIED AS TAILINGS: NO ELEMENTS WERE ELEVATED MORE THAN THREE TIMES BACKGROUND. LEAD AND ZINC WERE MODERATELY ELEVATED ABOVE BACKGROUND CONCENTRATIONS.
