Ausdrill Limited is on track to deliver a $48-$50 million half-year profit after tax, an increase of between 32 and 37 per cent on the previous corresponding period.
Ausdrill expects revenues for the half year to be around $500 million, in line with its $1 billion full year forecast.
The result would continue a seven year run of record profits for the company.
The WA-based mining services company said in a statement the final results remained subject to actual trading results in December 2011 and to foreign exchange fluctuations.
Ausdrill shares were up 14 cents to $2.96 at 11:55am WST today.
