The quartz‐gold‐stibnite‐bearing Consolidated Lode at Nenthorn, eastern Otago, contains abundant prismatic quartz crystals and hydrothermal breccia. Fluid inclusion data imply that boiling occurred during mineral deposition at about 190°C at very shallow levels, possibly within 120 m of the surface. This type of vein system may be common in eastern Otago. Gold may be found beneath Sb and/or Hg deposits formed by similar near‐surface hydrothermal activity.
