Exploration company Ormonde Mining has reported what it calls a 'significant increase' in the estimated resources at its La Zarza project in southwest Spain.
Ormonde is currently working towards a feasibility study at the project, where it is earning a 70% interest.
It says the new resource is estimated at 2.9 million tonnes of zinc, and is in addition to the existing copper and gold resources reported earlier this year.
'The addition of this significant polymetallic resource could enhance the economics of the La Zarza project quite considerably,' said managing director Kerr Anderson.
