The source states this is located at the junction of the Ord and Negri Rivers, which is near the Western Australian and Northern Territory border, about 10 kilometres south of the Darlu Darlu indigenous community. This un-named prospect has been arbitrarily named the Negri River chrysotile deposit by the writer.
It is a small deposit of chrysotile in serpentinised dolomite, overlying the Moonlight Valley Tillite. The chrysotile occurs as numerous lenticular seams with fibres up to one inch long.
In itself the deposit is uneconomic, even more so as this is asbestos related, and all mining of the material is banned in Australia for health reasons.
