Piedmont Lithium Ltd.: By-Product Mineral Resource Estimates

• By-Product Mineral Resource estimates completed for quartz, feldspar and mica
• By-Product Mineral Resources are wholly-contained within existing Mineral Resource model
• Previously announced metallurgical testwork demonstrates commercial value of by-products
• Scoping Study update to include by-products due within Q3 2018

By-Product Mineral Resource estimates were based on normative mineralogy compositions for 2,289 samples in 231 drill holes previously analysed for lithium. The results are shown in Table 1. The Mineral Resource estimates have been prepared by independent consultants, CSA Global Pty Ltd (“CSA Global”) and are reported in accordance with the JORC Code (2012 Edition).

The industrial minerals represented by Piedmont’s by-product Mineral Resource Estimates are fundamental inputs for regional industries that Piedmont can economically service given its location in the heart of the Mid-Atlantic industrial corridor. Piedmont is now updating the Scoping Study released on July 18, 2018 to reflect the production of by-product quartz, feldspar and mica, and expects to release this update within the coming days.

Keith D. Phillips, President and Chief Executive Officer, said, “Having confirmed a flow sheet to recover by-product quartz, feldspar and mica, we have now demonstrated a large-scale resource for each. We look forward to releasing an amended Scoping Study in the next several weeks and expect the update to further highlight the important advantages of our unique location.”

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Mineral Resources

The information contained herein has been prepared in accordance with the requirements of the securities laws in effect in Australia, which differ from the requirements of United States securities laws.
