In 1907, six prospectors discovered cinnabar, about one kilometre north-west of Karangahake. They named the lease Ascot, constructed a Novak Furnace, and by 1911 had processed 70 tonnes of ore for 1200 Lb of mercury. The lease was then abandoned.

The deposit occurs in host silicified rhyolitic tuff and siltstone, which forms a 30 metre capping over propylitised andesite. Cinnabar is found in a 1.5 metre thick kaolinised horizon, sandwiched between two sinter beds as red puggy (clay) seams, pug filled cavities lined with drusy quartz, whitish flinty quartz veinlets, and a persistent 30 cm quartz vein at the base of the horizon.
