Comments

Comment (Reserve-Resource): INDICATED AND INFERRED SUBECONOMIC RESOURCES

Comment (Deposit): THIS IS THOUGHT TO BE A HALO AROUND THE GLACIER PEAK DEPOSIT. PB AND ZN OCCUR IN SOME MASSIVE SULFIDE VEINS LOCALLY 18-21 IN. WIDE

Comment (Location): UNSURVEYED. IN SUIATTLE PASS

Comment (Development): NOT DRILLED BY BEAR CREEK BECAUSE AREA WAS PERIPHERAL TO THEIR AREA OF INTEREST

Comment (Workings): DRIFTS AND ADITS

Comment (Location): MRDS location-problem algorithm found lat/long NAD27 48-12-30N 120-56-52W disagreed with the political location of Snohmish county. Potential duplicate record 10277488 Deerfly, plots 1.1 mi to the SW, solidly in Snohmish county. However, the PLSS coords 31N 15E S11 and UTM coords, as well as the 1 mi E of Plummer Mtn. description were in agreement with the lat/long so the county name was changed to Chelan.
