Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Environmental Factors): THERE WERE NO MILL TAILINGS ASSOCIATED WITH THIS SITE. THERE WERE TWO ADIT DISCHARGES. ADIT #1 HAD MAJOR FLOW (O.025 CFS); ADIT #4 HAD A SLIGHT DISCHARGE (NOT SAMPLED) WHICH SEEPED INTO THE WASTE ROCK DUDMP. THE DISCHARGE FROM ADIT #1 EXCEEDED THE MAXIMUM CONTAMINANT LEVEL FOR CADMIUM AND HAD A PH MEASUREMENT OF 5.9. THE ADIT #1 DISCHARGE MAKES UP THE MAJORITY OF THE FLOW IN INTERMITTENT DAISY CREEK. OBSERVED RELEASES WERE DOCUMENTED FOR ARSENIC, CADMIUM, COPPER, IRON, MANGANESE, NICKEL, LEAD, AND ZINC IN SEDIMENTS AND WATER. THE MAXIMUM CONTAMINANT LEVEL FOR CADMIUM WAS EXCEEDED IN THE DOWNSTREAM DAISY CREEK SAMPLE, WHICH WAS DIRECTLY ATTRIBUTED TO THE SITE. THE ON-SITE SHAFT WAS OPEN AND WAS POTENTIALLY HAZARDOUS.
