Kentz Corporation's pre-tax profit rose eight per cent to 55.4m dollars in the first half as the engineering and construction group achieved a record backlog.
The company received an order intake of $979.4m, up 11% on the previous year. Backlog has grown 8% since the beginning of the year and up 12% since June 2012.
Revenue jumped 2% to $775.2m, driven by the strong performance of the Technical Support Services unit which posted a 47% increase in revenue.
The group's pipeline of opportunities has risen 17% over the next year to $15bn.
Chief Executive Officer, Christian Brown, said the first six months was one of the busiest periods of bidding activity ever undertaken in Kentz.
"Our blue chip clients continue to invest and demand the services that Kentz provide in engineering, constructing and maintaining some of the world's largest assets in the energy and resource sector," he said.
"The first half has seen our relationships with clients open up new regions for our business, and regions such as Africa and the Middle East continue to benefit from our long-standing presence, with further long-term contracts from satisfied clients. I look forward to updating you on the remainder of 2013 where we expect further contract and operational successes which will provide a firm grounding for 2014 onwards."
Kentz raised its interim dividend by 20% to $0.066 per share compared to last year.
Antofagasta's revenues in the first half dropped 12.1 per cent to 2.7bn dollars, reflecting a decline in copper prices and increased costs.
Earnings before interest, tax, depreciation and amortisation (EBITDA) fell 31.2% to $1.2bn following the average London Metal Exchange price of copper falling by 6.8% and realised copper prices sliding 15.5%.
Group net cash costs were up 27.3% to $1.26 per pound as a result of lower molybdenum volumes and lower molybdenum and gold prices.
Nevertheless, the group achieved an 8.4% rise in copper production to 364,100 tonnes and a 9.7% increase in gold production to 162,900 ounces.
Chief Executive Officer, Diego Hernandez, said the company remains on track to achieve full year production target of 700,000 tonnes of copper.
"Market conditions remain challenging with lower prices and higher costs impacting our revenues and profitability," he said.
"However, cash generation by the business was strong and the interim dividend has been increased by 4.7% to $0.089."
Net cash at the end of the period was up 12.5% to $1.5bn. Hernandez added that the miner would concentrate of controlling unit costs and optimise production from existing operations.
The optimisation of the Esperanza mine is on track with average throughput of 86,700 tonnes per day achieved and expected to reach 105,000 tonnes per day in 2015.
Esperanza recently satisfied the completion test under the project financing agreements and the debt is now non-recourse to the company.
