One of 5 vertical platinum mine shafts in the Kahuterawa Valley dug by Alexander Menesdorffer, circa 1900. The shafts are approximately 5 metres deep, are partially flooded and overgrown with ferns and moss. Each vertical shaft is fenced off from the surrounding Platinum Mines Loop Track which runs off the Toetoe Loop track.
An Hungarian geologist, Menesdorffer had two fifty acre claims in the Kahuterawa Valley and came to the Hardings Park area in the late 19th and early 20th century from Melbourne to search for minerals, specifically platinum. Traces of platinum were confirmed in 1906, but mining was never commercially established in the ranges.
