North Stradbroke Island sand miner Sibelco has had to cut jobs at its embattled Vance mine.
It comes as Sibelco announced that it reduce the workforce as it scales back production at the operation, according to the Bayside Bulletin.
However it still plans to continue production until June, when it is expected to have enough silica to meet current contract obligations.
After that it will cease production.
It has not stated how many jobs will be lost.
Sibelco came under fire in 2011 from then Queensland premier Anna Bligh, who put forth a timetable to phase out all mining on North Stradbroke Island by 2025.
At the time she said “mining may have been part of North Stradbroke's past, but won't define its future”.
Bligh went on to say that the Enterprise mine on the Island’s south will close by 2019.
The aim is to make up to three quarters of North Stradbroke national park territory by 2021.
Sand mining has been carried out on the island for more than 50 years.
