The company has said that it is most likely the third biggest site in the world with 5-8million tonnes of ore.
The Austrian company now wants to spend another €20 million on launching the mining, and building a processing plant near the mine. The launch is expected in 2014.
VSK plans to extract about 100,000 tonnes of soapstone per year and generate revenues of €20-30million per year. Its goal is to have a 20% share in the global market.
The project will create about 100 new jobs.
Soapstone is used in production of plastic and paper products as well as in the pharmaceutical industry.
