March 16 (Reuters) - Australian graphite miner Syrah

Resources ( SYAAF ) said on Monday it agreed with Tesla

to extend for a fourth time a deadline to resolve an alleged

default under their graphite supply agreement to June 1.

Tesla had previously issued a notice alleging that Syrah

failed to meet an obligation to provide conforming natural

graphite active anode material (AAM) samples from its Vidalia

facility in Louisiana, according to the company.

The notice required Syrah to cure the alleged default by

March 16, failing which Tesla could terminate the offtake

agreement covering supply from Syrah's 11.25 kilotons-per-annum

AAM facility in Vidalia.

The companies have agreed to amend the deal to extend that

deadline to June 1, subject to approval from the U.S. Department

of Energy.

The 2021 contract with Tesla, worth 8,000 tons annually for

four years, underpins Syrah's Vidalia facility and its broader

strategy to become a major U.S. supplier of non-Chinese

graphite.

Texas-headquartered Tesla issued the first default notice in

July 2025, saying Syrah had failed to deliver conforming active

anode material samples from its Vidalia processing facility for

use in electric-vehicle batteries.

Syrah said on Monday it does not accept that it is in

default but that both parties had agreed to extend the cure date

to June 1 while they work together to address the issue.

Shares of Syrah were up 2.9% at A$0.175 as of 2302 GMT.
