Photo 2. Drill core rubble from 60 m depth in hole RVD21-001 collared on the G1 gravity anomaly and breccia pipe target. Upper Photo: close-up photo of intensely clay - and silica-altered breccia with angular, dark grey silicified and lighter grey decalcified carbonate fragments with quartz-calcite veining in a clay rich orange gouge groundmass. Lower Photo: core box full of orange, iron-rich clay gouge holding together fragments of altered and silicified carbonate. The difficult drilling conditions encountered in G1 are the result of hydrothermal shattering during formation of the breccia pipe, and faulting.
