One hole has returned 10.7 metres at 8.6% zinc equivalent from 625.2 metres downhole and another returned 4.8 metres at 23.9% zinc equivalent from 379.2 metres downhole.
Results are from drilling at the recent Liontown East discovery, which is 700 metres from the eastern edge of the Liontown resource.
Red River is the only pure play zinc producer on the ASX, is free of debt and fully funded.
The first hole was drilled to test down-dip continuity of the deposit.
The 10.7 metre intersection included 0.4% copper, 1.4% lead, 5.5% zinc, 0.4 g/t gold and 13 g/t silver.
This intersection included 4.8 metres at 10.5 zinc equivalent comprising 0.5% copper, 2.1% lead, 6.3% zinc, 0.6 g/t gold and 18 g/t silver.
Up-dip continuity tested
The second hole was drilled to test the up-dip continuity.
The 23.9 zinc equivalent grade comprised 0.6% copper, 5.0% lead, 12.5% zinc, 4.2 g/t gold and & 120 g/t silver.
Another hole in progress
Another hole is in progress and has intersected 15.1 metres of massive and semi massive sulphide base metal mineralisation.
The known vertical extent of mineralisation at Liontown East is over 260 metres and known strike extent is up to 110 metres.
Red River began underground mining at the West 45 deposit in April 2017, with zinc concentrate production restarting at Thalanga in September 2017.
Planning for third mine
Production at Far West is expected by the end of 2018 and planning is underway for Waterloo which will be the third mine at Thalanga.
The company controls 420 square kilometres of land within a highly productive and prospective volcanic-hosted massive sulphide district, 65 kilometres from Charters Towers.
