Great Western's Tuckers Hill Quarry has been among those to enjoy a surge in business during the pandemic.
Quarry manager Darren House emphasised infrastructure works that had caused an increased demand for resources.
"Our production is up about 27 per cent from 2019," he said.
"That's based on more local roads funding and more infrastructure funding."
Mr House said he believed the high demand for resources for these projects would last for some time yet.
"At the moment the market is pretty hot," he said.
"The government's still spending money, so we're not expecting it to taper off just yet.
"The nature of our industry is it does happen, but we're currently grabbing the opportunity with both hands."
Australian Bureau of Statistics data reveals that for the 2019-20 financial year, minerals exploration spending in Victoria has increased by a third.
Minister for Resources Jaclyn Symes said the industry's success was good news for the entire state.
"Minerals and quarry products play an essential role in our everyday lives - they make up the houses we live in, the train tracks we ride on, and the computers we work from. Our resources sector helps us all."
