Dear Sir

RIU EXPLORERS CONFERENCE

Please find attached the Company's presentation to the RIU Explorers Conference being held in Fremantle, WA.

The Conference theme is New Floats, New Finds & New Mines. This presentation stays very much on theme focussing on Bass Metal's mining developments at its high-grade Zn-Pb-Cu-Ag-Au discoveries at Que River and it resource targets and growth plans around the Hellyer deposit.

The presentation does contain some new updates on the Que River trial mining programme which is progressing very well.

Yours Sincerely

Mike Rosenstreich Managing Director
