Bens Creek Group PLC has signed a non-exclusive marketing and sales services agreement with Avani Resources, the company's largest shareholder, that will see it take all the coal miner’s production.
Until now, all coal from the West Virginia site has been sold through Integrity Coal, which Avani will replace.
In a statement, Bens Creek and Avani said they will negotiate a separate sale agreement for the sale and purchase of each parcel of coal with terms for each parcel agreed by mutual discussion.
The contract can be terminated with three months' notice by either side.
Adam Wilson, Bens Creek's chief executive, commented: “We have been examining the possibility of expanding our sales channels.
"The addition of Avani, who bring tremendous subcontinent expertise (in particular in India, which is set to become the world's largest market), will provide us with both competition for our product and greatly increase exposure of Bens Creek coal within our target market."
