A 20,000 year old volcanic area actively depositing gold, etc from hydrothermal solutions. Approximately 250 kg of gold have been deposited in the last 1,800 years. Acid lake with pH ~ 2.
Lake Rotokawa is off the tourist trail, and is one of those areas locals visit. Sulphur mining occurred here from the 1960's to 1980's. The area is now a conservation reserve managed by the Department of Conservation, and the local Maori tribe. Permission to collect can only be given by these groups, and is usually reserved for the occasional mineral symposium visit. Specimens on Mindat were either collected during or shortly after the mining period, and before the reserve was declared, or during a permitted organised visit. Some areas are off limits totally due to their intrinsic value, beauty, or geological interest. The geothermal area has unique flora and fauna, including a leech, and algal stromatolites. There are no safety measures here, and we are obliged to warn falling into boiling hot water and/or mud is not good for health reasons.
The area contains a sequence of Pleistocene and recent volcanic rocks, underlain by a greywacke basement. A younger rhyolite tephra covers the surface. There are at least twelve eruption breccias preserved in outcrop, from several craters, the largest 1.5 kilometres across, partly filled with the acidic Lake Rotowara. (Krupp, et. al, 1987) claims the geothermal area has the highest concentrations of bedded sulphur for a geothermal area studied at that time, and the highest gold concentrations produced by a geothermal area in New Zealand.
The lake bubbles and steams from underwater springs, while to the north-east of the lake are a number of small craters, hot springs, mud pools, fumaroles etc. A terrace-like sinter deposit has developed along the north-east shore of the lake. Hot springs erupt from a number of north-east to south-west trending fractures, which merge at depth to join one of two local buried ring fractures as part of the Maroa caldera.
Hydrothermal alteration shows in a propylitic zone at depth, and shallower argillic zone. Sulphides sphalerite, galena, chalcopyrite and argentite are found as sporadic grains, with more pervasive pyrite. Gold rich fluids are rising to under the lake, and along the north-east shoreline, amounting to approximately 8000 ounces deposited over the last 1800 years, and about another 12 million ounces still under the crater. Gold specimens of any sort are not seen.
Layered green, yellow and grey muds discharging are rich in gold, arsenic, antimony, with high concentrations also of tungsten, thallium, mercury, silver, and gallium. The muds contain well crystallised kaolinite books, sulphur, alunite, silica, and rare realgar crystals. Various hots springs along the nearby Parariki Stream and Waikato River are lined with bright yellow and orange precipitates, and stock-work like silica veins, with fractures containing orange, red and yellow antimony sulphides as pigment, some orpiment, and realgar crystals to 1 mm. Bright red cinnabar may form coatings on fumaroles.
The breccias contain quartz with hyalite collected in the past, kaolinite, montmorillonite, illite, alunite, albite crystals in cavities, epidote, clinozoisite, adularia, rare pyrrhotite and radiating sprays of an allanite like mineral, botryoidal monazite, clots of Fe and Mn rich chlorite, wairakite veins at depth, framboidal iron masses, and frequently veined with silica and calcite. Apatite is honey-yellow specks to 1 mm, while titanomagnetite, barite, anatase, pyrite, and marcasite listed is usually grain sized.
The area is known for sulphur crystal specimens, found in the former mining pit, and sulphur 'blows' nearby. The sulphur deposit is saucer shaped, up to 17 metres thick, containing 17 million tonnes of ore grade sulphur (at a 10% sulphur cut-off). A series of rhyolitic pumice eruptions 1800 years ago, in the Taupo area severely curtailed the amount of new sulphur being added to the deposit. Rosickyite photographs are on Mindat, being an uncommon species, and not found elsewhere in New Zealand.
