Aircraft utilization, weather and cost data are given for t hree separate projects north of the sixtieth parallel in the Northwest Territories and the Yukon Territory. These operations, carried out by helicopter-equipped geological and prospecting parties, have cost $24 to $30 per square mile, depending principally on the distance from the base. They provide adequate s urface exploration of areas with 40 to 50 per cent rock outcrop. A good one-inch-to-one-mile geological map can be made.
