There were 10 entries this year, which were whittled down to four final nominees: Apollo Consolidated's Lake Rebecca gold discovery, Mincor Resources' Cassini nickel discovery, Aurelia Metals' Federation polymetallic discovery, and Rio Tinto's Winu copper-gold discovery.
For the first time ever, there were two winners announced at the AMEC Awards Dinner at the State Reception Centre in Perth's Kings Park last night.
"Once again the standard from all nominees was exceptional, making judging in each category a difficult task," AMEC CEO Warren Pearce said.
The 2020 Prospector of the Year Award was presented to Peter Muccilli, Robert Hartley and Mark Muller for Mincor's Cassini discovery in Kambalda; and Hilke Dalstra, Jennifer Maguire and Mawson Croaker for Rio's Winu find in the Paterson Province.
"Following some lean years for mineral exploration, it is exciting to see so many nominations for the Prospector Award and joint-winners for the first-time event. This is an excellent sign that our industry is recovering and growing," Pearce said.
No award was handed out in 2017 or 2018 as there were no eligible discoveries.
DDH1 Drilling's Murrary Pollock noted the Mincor discovery was a case of stepping out, while Winu was more of a new frontier discovery.
Cassini, the first nickel discovery in Kambalda in 20 years, was originally identified via regional exploration in 2015.
It has a reserve of 40,100 tonnes of nickel at 3.3% and is underpinning the A$68 million restart of Kambalda.
Winu was a first-hole greenfields discovery by Rio Tinto under cover in late 2017.
In July, Rio reported a maiden inferred resource is 503 million tonnes at 0.35% copper and 0.55 grams per tonne gold, or 0.45% copper equivalent, using a 0.2% copper cut-off, including a higher grade component of 188Mt at 0.68% copper equivalent, using a 0.45% cut-off.
The company could kick off development of the project as a small-scale starter operation as soon as next year.
The AMEC Community Contribution Award went to Salt Lake Potash and the Wiluna community for their partnership, which encompasses all aspects from education and employment for both the community and the company, to responding to cultural and community needs.
"Both SO4 and the Wiluna community are benefiting from this partnership by learning from and supporting each other, it truly represents what a partnership should be," Pearce said.
The AMEC Environment Award was Consolidated Minerals, which developed an AI program to automate the process of identifying the endangered northern quoll within camera trap photos.
"This AI application is quite remarkable and has huge potential to become a standard method for remote species identification with very minimal human interference."
The Australian Financial Review's Peter Ker won the Print Media Award, while Jarrod Lucas from the ABC won the Online Media Award.
Gina Rinehart was inducted into the Australian Prospectors and Miners' Hall of Fame.
Hall of Fame chairman Chris Cairns laid out a new vision for the organisation to become a virtual hub for Australian mining information and research for the general public.
