A combination of a higher US dollar gold price and lower Australian dollar drove the record.

According to Melbourne-based gold mining consultants Surbiton Associates, Australian gold production hit another all-time record of 321 tonnes (10.3 million ounces) in the 2019 financial year, up 11t.

June quarter production of 82t was the highest in more than 20 years, rising 5% over the March quarter.

According to the Australian government's Office of the Chief Economist old, exports totalled an estimated $18.9 billion in the 2019 financial year and were forecast to rise to $22 billion for this and the next financial years.

Those estimates were based on an average price of US$1361 an ounce this financial year and $1413/oz next financial year, or about A$1800/oz.

However, Surbiton director Dr Sandra Close said at a $2200/oz gold price, 2019 financial year exports would be worth $22.7 billion, while at today's price of $2300/oz, they would be worth $23.7 billion.

"The outlook for Australian gold production seems positive," she said.

"However, many things can happen, I can't predict the future and am very conscious of the many factors and uncertainties that affect gold prices, exchange rates and production."

Gold was already due to overtake thermal coal as Australia's fourth-largest export this financial year.

The Office of the Chief Economist has forecast Australian gold production to peak at 339 tonnes this financial year, and exports to peak at 370t.

Around 153t of annual capacity is expected to close between 2019 and 2024.

According to Surbiton, the five largest gold operations in FY19 were Newcrest Mining's Cadia (912,778oz), Newmont Goldcorp's Boddington (689,000oz) and Tanami (525,000oz), AngloGold Ashanti and Independence Group's Tropicana (518,172oz) and Newmont and Barrick Gold's Super Pit (490,000oz).

For the June quarter, the order was Cadia, Boddington, Kirkland Lake Gold's Fosterville, Tropicana, and the Super Pit and Tanami in equal fifth.

Gold miners surged this morning with the Saracen Mineral Holdings and Resolute Mining each up by more than 15%. Northern Star Resources, Regis Resources and St Barbara gained more than 10% each, Evolution Mining was up more than 8%, and Newcrest Mining gained 5.3%.
