MRI Trading has agreed a sales contract for a concentrate to be produced at Bardoc, with the other 50% of production to be in a conventional gold dore form.
Terms of the offtake weren't released but Bardoc suggested the deal "compares extremely favourably to the PFS".
Bardoc's PFS earlier this year outlined a 135,000 ounce per annum, seven-year project with a net present value of A$332 million, an internal rate of return of 32%, and pre-production capital of $142.4 million.
A gold price of $2100/oz was used for the ASX company's modelling.
A definitive feasibility study is due next quarter from the open cut and underground mining flagged development.
Bardoc said the offtake agreement would provide a "solid foundation for its project debt funding strategy".
Bardoc had $29.4 million of cash reserves at the start of the current quarter, having raised $24 million in July by issuing new shares priced at 7.8c each.
On a negative day for the ASX gold patch, Bardoc shares were up 3% to 7.6c, capitalising the company at $131.5 million.
