Shares of the Australian miner touched their highest since May 2007.

Reuters noted the deal followed Tesla's 'Battery Day' presentation last week when chief executive Elon Musk shared his vision of novel, proprietary Tesla batteries, following which Tesla stock lost more than US$30bn in market value.

Piedmont said in a statement cited by Reuters the agreement marked the beginning of its first US domestic lithium supply chain and that talks were ongoing over other sales arrangements.

The deal was conditional upon both companies agreeing to start deliveries between July 2022 and July 2023, the Australian firm added.
