Australia-based Wolf Minerals is set to open its metal extraction facility, the Hemerdon Mine in Devon, UK.
Wolf expects to sell the first tungsten from the Hemerdon pit in September, with the mine having taken around seven years to develop.
Wolf Minerals managing director Russell Clark told Proactive Investors in an interview that the company is set to become a leader in tungsten mining.
The Hemerdon mine is estimated to have 35.7 million tonnes of reserves, and expected to create 200 jobs once fully operational.
At least one lorry-load of tungsten is expected from the mine on a daily basis and would be delivered by road and rail to processors located in the US and Austria.
In order to obtain planning consent for the mine, the company said it worked with regional councils and the UK Environment Agency.
The mine is considered a potential major new source of global tungsten supply, and is set to produce around 3.5% of world demand in 2016.
After acquiring the Hemerdon project in December 2007, Wolf Minerals conducted extensive exploration programmes and completed a successful definitive feasibility study in 2011.
The project is being developed as a low cost, large-scale open-pit tungsten and tin mining operation.
