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

Bass Metals - Business Strategy 2007

Discovery Company - our business is mineral discoveries through exploration & acquisition

• 1. Explore for new deposits grass roots & target generation (ZFX JV & regionally)
• 1. Mine development & production at Que River (Pb-Zn-Ag (+Cu, Au) project.
• 1. Build base metal resource inventory QR deeps, Hellyer extensional targets, Farrell, Magnet & Obiriil
• 1. Build gold inventory from current 380k oz (Au Eq) at Mt Charter at MC extensions, Sterling Valley, Mt Selina, and QR

Que River Project

• Mined from 1978-91.

• Hellyer discovered in 1984 by same operator. BSM is the first new explorer since early 70's
• Numerous remnant resources and targets.
• · Initial focus is on shallow, high grade zones for open DIST
• · Potential for a significant mining project with minimal CapEx.

• Closer haulage distance (4km) & greater operation flexibility.
• Positive metallurgical The results for Que River ore through the Hellyer Plant
• Base Case = Pb-Zn-Ag to Hellyer Zn Conc.
• Optimisations include flotation recovery of Au, REGUL
• Hellyer-large plant, well run offering flexibility and capacity. .....

• · Stages 2-3 (under evaluation) And the stages 2-3 (under evaluation) Include Nico Lens, S-lens South, P North & QR32 as possible open pits.
• Stage 4 contemplates underground access to S-lens Deeps, remnant and new ore lenses in near vicinity to main PO Lens
• Further potential e.g. existing geophysical anomaly beneath S-lens with The anomalous Cu intersected to the south.
• 1st explorer since mine Olosed

Hellyer Mine Project - Summary

• High grade copper targets SFZ.
• • Zn-Pb-Ag stockwork targets = CFZ.
• Zn-Pb-Ag-Au (Ba) target Southern barite lens.
• Remnant Resource potential 0.6-0.7Mt at 8% zinc.

• Opportunity for Bass Metals because

• • new price environment
• smaller scale operation
• New exploration "eyes"
• Aim to build up base metal resource invento near to medium term production profile
