Avalon Advanced Materials is a Canadian mineral development company headquartered in Toronto, Ontario. Avalon specializes in critical metals and minerals with growing demand in new technology. The company has three advanced stage projects, all 100%-owned, providing investors with exposure to lithium, tin and indium, as well as rare earth elements, tantalum, niobium and zirconium. Avalon is currently focusing on its East Kemptville Tin-Indium Project in Yarmouth, Nova Scotia and Separation Rapids Lithium Project near Kenora, Ontario.

The East Kemptville Tin-Indium Project

Avalon’s 100% owned Tin-Indium project is situated 45 km northeast of Yarmouth in Nova Scotia, Canada. East Kemptville was an operating tin mine from 1985-1992 and was North America’s only large primary tin producer, before closing in 1992 following years of low tin prices.

In May 2014, Avalon entered into an agreement with the surface rights holder to secure access to lands for a limited drilling programme. Avalon has commenced the process toward converting this Special Licence into a mining lease, which the company anticipates completing in the first half of 2019.

In July 2018, Avalon finalized its Preliminary Economic Assessment (PEA) on the East Kemptville Project. The re-development model is an environmental remediation project involving processing the existing ore stockpile supplemented by selective mining of near-surface higher-grade tin mineralization.

The freshly mined tin allows generation of clean tailings free of sulphide minerals. These will be used to create a cover for the existing dry-stacked tailings, which will fully remediate the long term environmental liability. Avalon’s small-scale, re-development model utilizes existing infrastructure and previously-mined material, making the project a low energy, low green-house gas producer. The implementation of ore sorting is being explored and could further improve the project economics.

Most recently, the Company completed ore-sorting trials at East Kemptville, yielding positive results for both the low-grade ore stockpile and higher grade ore.
