Mining Industry Outlook

• Commodity prices under pressure due to sudden decrease in demand

• Early signs of recovery in copper and iron ore prices

• Gold likely to stay strong

• Thermal coal demand will help maintain price levels

• Some delay of mine expansions and Greenfield projects

• Most of the mining regions are affected except India and China

• Mining industry still looking forward to uptake in 9 – 15 months
