Whitehaven Coal has threatened to take legal action if Greens MP Jeremy Buckingham continues to make "incorrect" comments to the media after he recently wrote a press release about Werris Creek coal mine.

Whitehaven has also offered to "facilitate fact checking" of his comments before he sends out any statements in the future.

MP Jeremy Buckingham leads a mining protest.

The move is the latest manoeuvre by a mining company to silence the MP who was recently reported to police by Rio Tinto for alleged trespassing.

In a media release issued in November, Mr Buckingham referenced a University of NSW study which found the Werris Creek coal mine was in part responsible for nearby farmer's water bores going dry.
