John Joseph (Jupiter) Mosman (1861-1945).

(Extracts from Wikipedia)

Jupiter Mosman, was born in north-western Queensland. When he was a small boy, he turned up at Kynuna Station south of Julia Creek in western Queensland. Hugh Mosman, owner of Tarbrax Station, was visiting Kynuna Station at the time and adopted the boy and named him John Joseph Jupiter Mosman. He called him Jupiter because his eyes were "large, luminous, and as limpid as a planet".

Hugh Mosman sold his property, Tarbrax, and decided to go prospecting. He travelled with Jupiter, to Ravenswood where he became acquainted with the prospector George Clarke and together with a Mr. Fraser commenced a prospecting expedition in 1871.

The expedition set out from Ravenswood heading for the Seventy Mile Pinnacle, (now known as Mount Leyshon) after which they swung back towards the high bluff, (now known as Towers Hill), as it was an easily seen landmark.

In December 1871, the party arrived on the western side of the bluff and camped beside a creek where Jupiter discovered the gold-bearing brownstone quartz that led to mining of the goldfield they called the 'North Australian'. Their claim was registered in Ravenswood. It was the first mine on the new Charters Towers goldfield. Many mines were later established that  provided a much-needed boost in the development of north Queensland.

Hugh Mosman and his companions made much money from the Charters Towers gold fields, but soon went their separate ways. Hugh Mosman stayed longest but, after he lost his arm while using explosives, decided to retire to Sydney, taking Jupiter with him.

There Jupiter was sent to school in Newtown, NSW and afterwards to Lyndhurst College, Sydney, where he was baptised as Roman Catholic and christened John Joseph. There he did well at sports such as cricket, football and running. At cricket, he was a medium-fast bowler, a good fielder, and a sound batsman. He could run 100 yards in 11 seconds. Hugh Mosman was a keen horseman who enjoyed competing in steeplechase races. He taught Jupiter how to ride and about horse racing more generally. They rarely opened a gate, preferring to jump their horses over it.

After Jupiter had completed his schooling, Hugh Mosman and Jupiter returned to Charters Towers. When Hugh Mosman left Charters Towers in 1891, Jupiter decided he would join Hugh Mosman's nephew as a drover, taking a mob of cattle owned by Messrs Collins and White from Beaudesert near Kynuna to Wodonga in Victoria. The journey took six months and five days, and no beasts were lost.

Later Jupiter worked for Messrs Rourke and Monroe at Lolwoth Station at Dotswood. He worked at a number of other pastoral stations, including Wombiana, and Stockyard Creek with Messrs Soilleux and Roberts.

When he had the opportunity, Jupiter went prospecting and is credited with discovering other mineral-bearing areas.

He retired and lived at Eventide Home for the Aged in Charters Towers where he died on 5 December 1945 aged 85.
