Satelite View

Comments

Comment (Environmental Factors): ONE DISCHARGING ADIT WAS IDENTIFIED AT THE SITE. THE DISCHARGE SEEPED INTO WASTE ROCK PRIOR TO REACHING SURFACE WATER. A SAMPLE OF THIS DISCHARGE HAD A PH OF 7.45. NO MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED IN THE ADIT DISCHARGE. AN UNNAMED TRIBUTARY FLOWED THROUGH THE SITE AND DISCHARGED INTO THE SOUTH BOULDER RIVER. OBSERVED RELEASES TO THE SOUTH BOULDER RIVER (SEDIMENT) WERE DOCUMENTED FOR ARSENIC AND COPPER. POTENTIAL SAFETY HAZARDS IDENTIFIED AT THE SITE INCLUDED ONE OPEN SHAFT AND TWO OPEN ADITS.

Comment (Deposit): PROPERTY COULD BE USGS GSC ID# WO13407 AS LISTED IN MILS. SO MAS PROPERITES 0300570564 AND 0300570794, THE LAT/LONG OF THESE OTHER PROPERTIES ARE CLOSE ENOUGH TO CAUSE SOME CONFUSION.
