Australian shares flat as mining losses counter banks, energy boost

June 12 (Reuters) - Australian shares were largely unchanged on Thursday, as miners partially offset strong performances in banks and energy stocks, while U.S. President Donald Trump's hint at extending the trade negotiation deadline eased concerns over imminent tariff hikes.

The S&P/ASX 200 index .AXJO held its ground at 8,593 points, as of 0108 GMT. The benchmark on Wednesday touched a record-closing high of 8,592.1 points.

Overnight, Trump signalled openness to extending the July 8 deadline for trade talks before higher U.S. tariffs take effect, though he expressed doubt that an extension would be necessary.

China and the United States, Australia's top export partners, reached a framework deal, boosting investor optimism for a lasting resolution between the two superpowers and easing fears of further market disruption.

However, the lack of specific terms leaves the possibility of future tariff disputes.

Chinese export-reliant miners .AXMM slipped 0.4%, set for their weakest session since June 2, if current momentum holds.
