Figures published yesterday by the Department for Energy and Mining show South Australia’s mineral resource production for the 2020 calendar year reached $7,059,477,619, up from $6.9 billion in 2019.

It is only the second time the sector has topped $7 billion in a year and is the second-highest year on record behind the $7.312 billion produced in 2014.

The 2020 figure was achieved despite a struggling oil and gas sector that contributed $1.34 billion compared with $1.65 billion in 2019 and $1.9 billion in the record year of 2014.

Star improvers in 2020 were gold, which contributed $952.5 million compared to $554 million in 2019 and iron ore $1.23 billion in 2020 up from $907.3 million in 2019 with both metals benefitting significantly by massive price hikes.

Uranium production in 2020 decreased to $521.4 million from $538.7m in 2019.

The slide in oil and gas production value coincided with plummeting oil and gas prices in 2020 as global travel ground to a halt during the pandemic.

However, it is also part of a longer-term trend that shows the value of the sector has declined every six months since the first half of 2019 when it contributed $847.6 million through to the $613.5 million it added in the second half of 2020.

Copper continued to be the state’s largest contributor in 2020 with $2.429 billion worth of production. This included $1.35 billion in the second half of the year, which is the highest six-month copper total in the state’s history and bodes well for another strong year in 2021.

Copper prices jumped by 24 per cent in the second half of 2020 despite the increase in the value of the Australian dollar compared to the US dollar.

The copper price has surged a further 17 per cent in the first four months of 2021 to more than $12,000 per metric tonne in April.

This period has coincided with a 25 per cent increase in copper production at BHP’s Olympic Dam for the nine months to March 2021.

The state’s largest copper mine produced 100,000 tonnes of copper in the second half of 2020 and a further 55,000 tonnes in the March Quarter this year, the highest quarterly production at Olympic Dam in the past five years.

The state’s next largest copper producer, Oz Minerals, also reported significant increases in copper production for the second half of 2020 at its South Australian mines at Prominent Hill and Carrapateena.

This was mainly due to the ramping up of production at Carrapateena, which began commercial operation in late 2019.

Other contributors to the 2020 production figures were opals, $17.1 million (down from $18.46 million in 2019), industrial minerals $277.4  million in 2020 (down from $509.9 million in 2019). Construction materials such as limestone and dolomite were steady at $235 million.

According to figures from the SA Chamber of Mining and Energy (SACOME), the state government received $311 million in mining royalties for the 2019/20 financial year, up from $299 million the previous financial year and $207 million in 2015/16.

SACOME CEO Rebecca Knol said although the 2020-21 State Budget predicted royalties to be $301m this financial year, it was not yet known how the latest production figures would impact this figure.

“During 2020, the resources sector demonstrated both its resilience as a sector and its importance to the state’s economy,” she said.

“Copper, gold and iron ore were the driving forces behind the growth in 2020 with BHPs Olympic Dam, OZ Minerals Carapateena and Prominent Hill operations and SIMEC’s Middleback Ranges operation collectively contributed to this significant lift in productivity.

“These results should be sending a very clear message to South Australia graduates, school leavers and apprentices that the resources sector is in a growth phase and providing well-paid employment in both metropolitan and regional areas.”

Export commodity figures for April released by the ABS yesterday show SA had $1.321 billion in exports in April following more than $1.1 billion in exports in February and March.

The April figure is the third highest on record behind December 2013 ($1.389 billion) and December 2018 ($1.371 billion) and puts South Australia on track for a record export year in 2021.

Specific state details will not be released until next week but they are expected to show SA’s growth was driven by copper, gold and cereals such as wheat and barley.

Nationally, exports in April increased slightly from March to $35.95 billion in April but was $4.92 billion (16 per cent) on April 2020 driven by a $5.21 billion metalliferous ores on the back of booming iron ore, copper and gold prices and a $556 increase in cereal exports following an improved winter crop last year.
