New Board structure in place O lan Smith takes the lead as Chairman Greg Robinson joins as an NED Amber Rivamonte joins as Executive Director of Finance . In an extended - and perhaps heightened - period of ongoing uncertainty , set within a COVID - focused world , Rex Minerals has been very active . We have maintained our field program at Hog Ranch , significantly improved the metrics at Hillside and rebuilt the Board to drive the Company into its next and defining phase of development . Rex is very much a 2-1 investment . Hillside and Hog Ranch are each company - makers in their own right and underpinned by strong demand outlook and healthy commodity price forecasts . On top of this , following a successfully completed placement during the June quarter , Rex Minerals has zero debt .
