5E Advanced Metals (ASX:5EA) said that a "major domestic LCD glass manufacturer," to which the firm shipped twenty tons of borates, began testing with the firm's boric acid being dispatched into the glass furnace, according to a Wednesday Australian bourse filing.

The manufacturer had previously performed a laboratory bench testing program where 5E's boric acid passed all required specifications. It then required 5E to perform a supply-chain trial where two tons of product were shipped in a container across the Pacific Ocean. These tests paved the way for the current tank trial test.

Results are expected before year-end.

5E's shares rose 3% in recent trading on Thursday.
