Power problems mount for U.S. miners

Denver — The dramatic rise in electricity costs for mining operations in the western U.S. continues to threaten the industry. Blackouts are again keeping Californians in the dark, and deregulation gone haywire has sent costs skyrocketing.

Mining first felt the pinch in the fourth quarter of last year, particularly in Arizona and New Mexico. Phelps Dodge (PD-N), which operates energy-hungry copper mines there, saw electricity costs triple to US11 per kW.

Phelps Dodge reported no material changes in electricity costs for the first quarter of 2001, though it did report that total cash costs per pound were 10 higher than in the corresponding period of the previous year, with most of the increase coming from energy-related costs.

Some employees at the company’s operations in New Mexico and Arizona have been laid off, and shutdown warnings are still in effect.

The cost increases have put further strain on an already-depressed industry. Moreover, prices for the red metal are down to around US75 per lb. at a time when the U.S. economy is foundering. If the country slips into a recession, copper usage would fall further.

Meanwhile, the Federal Reserve has systematically cut interest rates in an attempt to stave off recession, while the Bush administration has tried to bolster power generation. It is also promoting increased oil and gas drilling in an effort to combat high prices for fossil fuels.

Mines are doing whatever they can to contain the spreading power problem.

Golden Sunlight

In Montana, Placer Dome (PDG-N) has received approval from the state public service commission for supplemental power at the Golden Sunlight mine. The operation’s long-term contract will expire at the end of the second quarter. Placer had been paying US2.9 per kW-hr., plus 0.8 for transmission and distribution charges, though current market prices are much higher. Under the agreement with the state, Placer will receive 10 MW, enough to get the mine through the third quarter at a cost of as much as US4.2 per kW-hr. plus another US1 for transmission and distribution.

Open-pit mining should be completed by the end of June, after which time the company will process lower-grade stockpiles. Production should reach 173,000 oz. in 2001, though if Placer cannot secure power for another year, it may have to shut down the operation.

In Nevada, Newmont Mining (NEM-N) got relief from higher energy costs when the state legislature froze the company’s electricity rates at US6.6 per kW-hr. through the remainder of the year. Also, the company signed a letter of intent for a 15-year agreement to buy 150 MW from El Paso Merchant Energy, a subsidiary of El Paso Corp. The electric company proposed building a 480-MW power station near Newmont’s operations at Carlin, Nev. However, even if construction were to begin immediately, it would be more than a year before the station could supply any energy.

Barrick Gold (ABX-T) has been lobbying the Nevada government to allow large consumers to buy electricity from suppliers other than the regional utility company, Sierra Pacific Power.

Barrick has considered other sources of power but is dismayed at the state of the market. “The power is there, but at pretty exorbitant prices,” laments John Carrington, the major’s chief executive officer.

Mining, along with the gaming industry, is one of Nevada’s largest consumers of power. Newmont and Barrick represent the two largest private users.

BPA frustrated

The power crunch is having an even harsher impact on the aluminum industry. Producers in the northwestern states are being cajoled into shutting down smelters for up to two years in an effort to free up electricity for individual consumers.

The Bonneville Power Administration, which controls much of the region’s hydroelectric power, wants to renegotiate recently signed long-term contracts with Alcoa (aa-n) and Kaiser Aluminum (klu-n), and curtail power use to avoid rolling blackouts.

The aluminum industry, represented by 10 smelters and more than 6,000 jobs, is balking at the proposal, claiming it is being blamed for the problem. Like copper prices, aluminum prices too are depressed. Local operators have enjoyed cheap power for the past 50 years, but reopening the smelters at current rates may be impossible.

Not all big power users in the northwest are unhappy about rising electricity costs. Across the border, in British Columbia, Cominco (CLT-T) has turned a tidy profit on the sale of electricity from the Waneta hydroelectric dam on the Pend Oreille River, which supplies the Trail zinc smelter.

Spot prices have increased more than ten-fold in the past year to US$350 per MW-hr. in first quarter of 2001, up from US$24 in the initial three months of the previous year.

In fact, Cominco has increased its curtailments of zinc production in lieu of selling the power several times this year. It expects to cut production by as much as 100,000 tons, with a big chunk of that coming during August and September, when the smelter will be closed for maintenance.

To date, Cominco has not needed to lay off any employees at Trail, having engineered the curtailments around employee vacation time.
