The minister of the economy accepted the agreement in June and, if granted by ANRM, the association licence would give Vast's 80%-owned subsidiary African Consolidated Resources the right to mine at Baita Plai.
The company said the joint application was in its final stage after a long legal and administrative process and it said it had "reason to believe that the actual grant of the association licence will follow shortly".
It will then be able to start mining activities.
In January, Vast signed an offtake with Mercuria Energy Trading for up to 100% of the copper and zinc concentrate produced at its Manaila and Baita Plai projects in Romania.
Vasta'a shares moved up 1,52% on the news to 0.64p (US0.83c) Monday.
