The company poured 45,400 ounces in the September quarter and added about US$20 million to its treasury.
Speaking at the Diggers & Dealers conference in Kalgoorlie, WAF's executive chairman Richard Hyde said he expected fourth quarter output to be "much better" and believes the company can have a "real good shake" at producing circa 300,000 ounces in calendar 2021.
No technical issues have arisen at the new project.
Hyde said an early debt repayment would be made, with the company focused on repaying the $200 million facility provided by Taurus.
He also suggested Sandbrado would be a plus-200,000oz per annum operation for plus-10 years given the drilling indications at depth at the key M1 South deposit and the addition of the Toega deposit.
Meanwhile, exploration within trucking distance of Sanbrado is being ramped up with a $7.5 million budget underpinning big drill programs.
An update on resources, reserves and potential production guidance for 2021 is expected later this quarter.
Shares in WAF were down 6% to A$1.13 in midday trade, capitalising the company at $995 million.
