| Deposit | Mineralization occurs in pervasively altered volcanic rocks containing anomalous amounts of antimony, arsenic and mercury, indicator elements for epithermal gold deposits. Mineralization is comprised of stockworks and veins which are typically open spaced and vuggy grading into wider silicified zones at depth. The mines in the area worked oxidized deposits with all workings stopping just above sulfide ore. High-grade gold pockets (typically greater than 30 g/t Au (1 opt Au) were located with a metal detector and appear to be localized along a fault surface. Most of the gold is found along the footwall, where open-space-filling occurred during gold deposition; gold was concentrated in areas where solutions poold. The presence of some microbreccia and pebble-breccia fragments suggest that the fault was reactivated post-mineralization. Occasionally euhedral gold leaves are found rolled up with and within small breccia fragments, also indicating post gold movement. Mineralization appears to follow bedding plane faults and fractures that crosscut bedding, the largest observed gold-bearing strikes N. 55-60E and dips to the 55-65 NW. A second location where gold was found in situ is at the intersection of N-S and NE-SW- trending structures that converge and can be traced to the surface. Evidence exists of supergene enrichment in the upper zones where some exceptionally rich pockets of gold were found concentrated in favorable structural traps. Thus, crystalline native gold is believed to be bi-modal in origin. |
