The group announced earlier this month that operations at Baita Plai had paused temporarily due to safety concern over a railway bridge between the mine and the flotation plant.
The brief hiatus was expected to delay first concentrate sales by three to four weeks.
Vast recently raised £1.68mln of new capital via a share placing, with some of the new funds earmarked to support the company as it resolved the transport infrastructure problem.
As the new bridge installation takes place the company said it will provide footage of the process via social media.
The funds raised this month will also support the advancement of some development work and construction costs, respectively helping Vast access higher-grade ore and progress a second production line to maintain the schedule.
Additionally, it will cover due diligence and legal costs associated with its debt financing process.
