The first gold was found by Frederick Warner the expedition's surveyor on 6 August and further deposits were located on following days. However Hann thought they were not in commercial quantity; as a result James Venture Mulligan who in 1873 followed up Hann's report and announced richer deposits is credited with the discovery.
"HANN--On the 5th April, William HANN, of Maryvale, North Queensland, accidentally drowned whilst bathing in the sea at Townsville, leaving a wife and two daughters to mourn the loss of an affectionate husband and loving father, aged 52."
In addition to the above death notice, the following article appeared in the Brisbane Courier, dated 6 April 1889, suggesting that the drowning was not accidental and took place at night.
"A Townsville telegram dated 5 April states that William Hann of Maryvale Station, one of the oldest of the northern pioneers, committed suicide by drowning, in the bay in front of the Queen's Hotel during Thursday night."
A memorial to William Hann was erected in 1959 in Lissner Park in Charters Towers. The stone used in the memorial was taken from Basalt River near the Bluff Downs homestead where William Hann first settled.
