IMC'S TAILINGS AND SPOILS AVOCA, Co Wicklow (PL 3849 and PL 3850)

The Avoca mines have left a legacy of spoil heaps on the landscape, pollution in the river, and most importantly, metal that has been unrecoverable until now.

• An Irish government commissioned report indicates the spoils (c.1m cubic meters spread over 28 ha) contain significant concentrations of copper (56-11,344 milligrams per kilogram [mg/kg]), zinc (44-7,404 mg/kg), lead (112-41,353 mg/kg), and arsenic (18-3,903 mg/kg). Analyses of seepage from the Mount Platt spoils (c 1m tons) indicate that the spoils are acid generating resulting in seeps with low pH (typically < 3) and very high concentrations of copper, zinc, iron, and aluminium.

IMC has signed a Heads of Agreement with Trove Metals Limited (Trove) which is expected to lead to a Joint Venture Agreement, subject to the approval of the Minister for Communication, Climate Action and Environment.

• IMC will use proven technology (the processing method will be microgravity separation (MGS) combined with dense media separation (DMS)), to both clean up the environmental legacy and exploit the remaining metal that lies on the surface. One significant affect of the leaching that has occurred over the years is the liberation of fine gold grains from the minerals in which they were previously trapped. Our innovative combination will not use harmful reagents to separate ore from waste, but will exploit the high density of the two main economic metals in Avoca, gold and lead.

• IMC is engaged in extensive sampling, petrographic, mineralogical and metallurgical testing, and results to date have more than justified, and provided adequate data for, a JORC compliant resource estimation of these spoils. This has commenced. IMC is also carrying out deep sampling to acquire expected accumulations of free gold at base of spoil heaps. Extended metallurgical and processing tests.

According to the Fraser Institute, Ireland has the most attractive mining policies on the globe. Ireland’s commitment to sustainability means that mine waste reclamation is the obvious next step for Ireland’s well-established mining industry.
