Irish Salt Mining and Exploration is the biggest salt mine in Ireland and is currently working around the clock to cope with demand for its rock salt.
The US-owned company is churning out approximately 4,000 tonnes of rock salt a day, which is being used on icy roads here, the Republic and Britain.
A spokesman for the company said: “They are working flat out at the minute.”
Some councils only have around two days’ worth of salt in storage and the company is trying to ensure enough salt gets to local authorities.
