Hemerdon tungsten mine waste provides unique sustainable supply of secondary aggregate
CONSTRUCTION materials suppliers GRS Group have secured an exclusive deal to bring to market millions of tonnes of granite arising from British tungsten mining for use as sustainable construction aggregate.
The unique multi-million-pound venture sees GRS join forces with Tungsten West, operators of the recently reopened Hemerdon tungsten mine near Plympton, Devon, to sell high-quality secondary aggregate and transport it nationwide by sea and rail.
Hemerdon mine is internationally important because it is the world’s fourth largest tungsten reserve (and the second largest to comply with CRIRSCO standards) as well as being Europe’s only source of tungsten.
But mining tungsten also gives rise to thousands of tonnes of granite, ideal for a full range of secondary aggregates from bulk fill materials to single sizes for concrete and many other construction applications.
GRS will use their well-established freight network – in particular rail and marine – to efficiently transport the aggregate to construction projects across the south of England and potentially further afield. The granite aggregates will be processed on site at Hemerdon helping to sustain several local jobs.
Jon Fisher, chief executive of GRS Group, said: ‘This is a true symbiotic collaboration between two like-minded businesses with shared ambitions. Not only are we helping the UK to remain self-sufficient in essential minerals, but we’re also distributing them in the most sustainable way possible.
‘GRS already trade and transport almost 20 million tonnes of construction materials every year – around half of which is from recycled or secondary sources – and this deal reinforces our whole ethos to make the best use of the UK’s available resources.’
Max Denning, chief executive officer of Tungsten West, said: ‘Tungsten West are extremely excited to partner with GRS, especially as they’re the UK’s leading aggregates trading company with an exceptional reputation for success.
‘By GRS applying their years of experience and success across all industry verticals within the construction materials sector, Tungsten West can offer a significant new mineral resource, at scale, to the UK market. GRS bring a wealth of experience, credibility and strategic thinking that complements our approach.’
Starting this month (September 2021), GRS expect to ramp-up secondary aggregate volumes from Hemerdon to distribute more than a million tonnes each year for the next decade and beyond. After a short lorry journey from Hemerdon, the aggregate will be loaded on to ships at Plymouth for transportation to other ports around Britain.
Some of the aggregate will also be hauled a short distance by road to nearby Marsh Mills (between Plymouth and Plympton) where it can be loaded on to trains for onward distribution via the rail network.
Through their Cornish subsidiary Maen Karne and London-based business Walsh, the GRS Group already successfully transport secondary granite from the Cornish china clay industry into London by sea and rail.
