Subject category Comment text
Deposit BRECCIATED VEINS. WHERE VEINS ARE THICK, BRECCIATION OF QUARTZ CONFINED TO PORTIONS ADJACENT TO WALLROCK. ORE OCCURS AS A LOOSE, FRIABLE VEIN-FILLING OF BRECCIATED QUARTZ AND AS BRECCIATED SCHIST WALLROCK. ORES OF TYLER MINE OCCUR IN FIRST CASE WHILE ORE OF ASTER MINE REPRESENTATIVE OF LATTER. ORE BODIES 1-30 FT. IN THICKNESS SEPARATED BY PINCHES IN VEIN OR LENSES OVERLAPPING WITH NARROW LAYERS OF SCHIST INBETWEEN.
Deposit CONSOLIDATED WITH THURMAN AND ASTER MINES COMPRISING 14 CLAIMS. SEE PANAMINT MINES CO. TOTAL 14 CLAIMS ; INFO.SRC : 1 PUB LIT
