NOVA SCOTIA – Closed since 1992, the former East Kemptville tin-indium mine may reopen if Avalon Advanced Materials of Toronto has its way. The company proposes to reprocess stockpiles of low grade ore supplemented by near surface higher grade material. The project would have a life of at least 15 years.

Avalon is currently applying for the needed permits and approvals, including a mineral lease and negotiating the transfer of existing surface tenures. The company is currently preparing a preliminary economic assessment for the project. Once permits and financing are in place, a 12 to 16-month construction period would be needed before reopening.

A mineral resource for the Main and Baby zones was prepared in 2015 after infill drilling. The measured and indicated material was 23.0 million tonnes at 0.153% tin plus an inferred resource of 14.2 million tonnes at 0.139% tin. An update is underway. The low grade stockpile contains another 5.9 million inferred tonnes grading 0.112% tin.

Avalon plans to rehabilitate the entire site upon closure. That goal includes reprocessing 6 million tonnes of previously mined low grade ore so that it will no longer create an acid drainage problem.

The company is also advancing its Nechalacho rare earths project in N.W.T. Learn more at www.AvalonAM.com.
