Dec 16, 2010 (S Butorac) - Altered zones in a diabase sill contain numerous small quartz veins. The principle alteration zones strike E, appear to dip vertically, have widths ranging from 10 to 100 feet, and have been traced by drilling over strike lengths of up to 600 feet. Copper assays were generally less than 0.5% Cu; best assay was 2.21% Cu over a core length of 2.5 feet. (ODM 1969 MRC 12 P 71). Best uranium assays averaged 0.14% U3O8 over 6.0 feet. (OGS 1983 MDC 25 P 44).
