Jun 26, 2013 (G Seim) - SER-87-11 returned a high assay of 0.012 opt Au, over 5 feet in the ultramafic to mafic metavolcanic flows while the porphyry averaged 0.012 opt Au over 50 ft., with a high assay of 0.017 opt Au over 5.0 ft. SER-87-12 returned a high assay of 0.30 opt Au over 3.0 ft. in mafic metavolcanics with several short intervals returning 0.010 to 0.021 opt Au. (all in mafic metavolcanics). Four samples from the rhyodacite-dacite returned values ranging from 0.011 to 0.013 opt Au over sample widths ranging from 1 to 6 feet.
