One of the unexpected findings from executives and analysts attending the monstertruck02.jpgCESCO and CRU copper conferences in Santiago, Chile: Women are better drivers than men in those house-sized trucks roaming surface mines around the world. They’re said to be more cautious and that reduces wear and tear on the 13 feet-high tires they rumble around on.

The largest of these trucks, manufactured by Caterpillar, Komatsu of Japan and Germany’s Liebherr, can carry almost 350 tonnes. Each tire can cost up to $125,000 but they can easily be flamonstertruck01.jpgttened by a fist-sized stone wedged in its treads.

To avoid blowing a tire, a mine might reduce the bucket load even when operating full-out to keep up with global copper demand. Light trucks will speed ahead of the big ones and radio in debris on the mine roadbed. “You get guys jumping out of vehicles throwing stones off the road,” one analyst told me.
