Cornish Metals Inc has ordered long lead items of two winders and engaged project management consulting services to develop the South Crofty tin mine in Cornwall.
COLLABORATION
Yorkshire engineering firm Qualter Hall & Company Ltd will design, manufacture, supply, instal and commission the service winders to be used in the New Cook’s Kitchen shaft.
“Qualter Hall has been supporting activities at South Crofty for over 50 years,” said managing director Gifford Brown.
“The full turnkey scope of work incorporates complete in-house capability, from initial design and manufacturing right through to final installation and commissioning, all delivered by our dedicated team here in Barnsley.
“This collaboration underscores Qualter Hall’s continued expertise and leadership in the
design and delivery of critical mining and hoisting infrastructure and we look forward to working
with the South Crofty team again.”
The 3.2-metre single drum 1,200 kilowatt service winder has a maximum hoisting
capacity of 12,500kg gross at a speed of up to 7.3 metres per second and will be used for production personnel and equipment.
Cornish Metals added: “This winder will replace the existing 2.3m single drum 132 kW winder currently in place and used for pre-production access and shaft refurbishment activities that will be relocated to the Roskear shaft.
“The 3.2m single clutch, double drum 1,200kW production winder will be used to hoist rock from depth to near-surface.
“With a maximum hoisting capacity of 11,500kg gross at a speed of up to 7.9 m/s, it is designed to handle the hoisting demands required for the proposed production rates as detailed in the South Crofty preliminary economic assessment.”
As a project manager for the mining, energy and infrastructure sectors, Technical
Management Group Ltd (TMG) will provide project management consulting services from construction to full production.
Cornish Metals said that the Toronto-based firm was its “best suited” partner and would integrate with its existing team.
“South Crofty represents more than just a return to production – it’s a statement of what’s possible when the right team is assembled with clarity of purpose,” added TMG president Kenny MacEwen.
“TMG is here to bring structure, discipline, and momentum to the project alongside
Cornish Metals.
“Our mandate is clear: support a successful build and help position South Crofty as
a modern mining operation ready to thrive.”
