| Deposit | Gold values are generally erratic occurring with quartz, pyrite and iron oxides in stockworks of veins and veinlets and as disseminations in silica-flooded zones. Samples were taken from areas of brecciated, silicified argillite, and rubble breccia, laced with quartz veinlets, quartz matrix to breccia, stained red with hematite. Ore-grade gold-silver mineralization was restricted to the vicinity of the Tomasina fault and associated structures. Higher grades were associated with siclicified, quartz-veined structures and breccia zones up to ten feeet thick Lower grade mineralization occurs in moderately broken and veined zons in the hanging wall and near structural intersections. |
