The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Deposit): THE APEX MINE OCCURS IN ROCKS OF THE SNOQUALMIE BATHOLITH, NORTHERN PHASE, WHICH CONSISTS OF GRANODIORITE AND TONALITE AND IS LIGHT COLORED, MEDIUM CRYSTALLINE, AND MOSTLY EQUIGRANULAR AND HAS HYPIDIOMORPHIC TEXTURE. THE ROCKS ARE COARSELY JOINTED AND CONTAIN BIOTITE AND HORNBLENDE AND LOCALLY CLINOPYROXENE. AGE OF THE NORTHERN PHASE IS ABOUT 25 M.Y. BASED ON INTERPRETATION OF NUMEROUS DISCORDANT K-AR AGES OF BOTH HORNBLENDE AND BIOTITE (TABOR AND OTHERS, 1982, P. 8). ; INFO.SRC : 1 PUB LIT
Comment (Development): ECON.COM: PRODUCED 300 TONS WORTH $80,000 PRIOR TO 1901.
