The first parcel, officials said, came from the start-up upper benches of Flinders and Bass pits.
With the first bars poured, it remains on schedule to deliver its monthly ore target of 40,000t.
In fact, Mincor added, the first toll parcel of ore for August is already stockpiled and prepared for delivery.
Managing director Peter Muccilli noted that, as the region's gold assets had little value assigned to them just a few years ago, the achievement is a testament to the hard work of its workers, consultants and contractors as Widgiemooltha becomes an active mining operation with cash flows forthcoming.
"The gold cash flows will help to accelerate the company's active ongoing nickel exploration programmes, which are aimed at fast-tracking the development of Mincor's high-quality Kambalda nickel portfolio to take advantage of the forecast growth in the nickel market over the next few years," Muccilli added.
Widgiemooltha, which is targeting 71,000oz of gold over a mine lifespan of about 29 months, has a 12-month processing agreement with Westgold Resources to run ore through its Higginsville plant.
