General

Formed in 1976, the company actively pursued the construction of the plant in Leyte which was completed in 1983 to signal the Philippine Government's industrialization plans for the country. PASAR's primary product is electrolytic copper cathodes, the raw material used for manufacturing various kinds of electric cables, telecommunication wires, copper shapes and copper-alloy products. The PASAR Copper Cathode is registered as Grade A Copper in the London Metal Exchange (LME) and as COMEX High Grade Copper in the Commodity Exchange (COMEX) Division of the New York Mercantile Exchange (NYMEX). It is also listed in the Shanghai Futures Exchange.

The location of PASAR copper smelter and refinery in Leyte in the central Philippines has resulted in many advantages for the company and its partners. The port possesses a deep-harbor facility which is being reconstructed to berth and handle vessels up to 50,000 DWT. It lies in the center of the Philippine archipelago, ready to serve the smelting needs of the country's reviving mining industry.  The complex includes pollution abatement facilities; port and bulk handling facilities; an airstrip; a medical facility; and housing, recreation and educational facilities for company personnel and their dependents.  The PASAR plant complex occupies 80 hectares in the 424-hectare Leyte Industrial Development Estate (LIDE). Completed in 1983 at the cost of US$300 million with the capacity to produce 138,000 metric tonnes of Grade A electrolytic copper cathodes annually, it was expanded in 1993 to its current production capacity of 172,500 metric tonnes per year.

In June 1999, a consortium of Philippine investors and Swiss trader, Glencore International AG, procured 90% of the Philippine Government's shareholding and its receivables from PASAR. This acquisition was carried out as part of the country's privatization program, thus, transforming the company into a privately-owned corporation.  Subsequently, the shares owned by the Japanese consortium were sold to a privately-held company.  Now, the capacity of the smelter has been expanded to 720,000 mtpy of concentrates in 2006, and the refinery will be expanded to 215,000 mtpy of cathodes by mid-2007.  The design of the plant was patterned after Japan's Tamano smelter and refinery plant, considered as one of the world's most efficiently-run smelters. The flash smelting process developed by Outokumpu Oy of Finland and modified by the Mitsui Mining and Smelting Company, was adopted for more flexibility in processing different grades of copper concentrate, high recovery of sulfur, and reduced power and oil consumption.  Copper concentrate, the basic feedstock undergoes a smelting and refining process in which impurities are removed and refined copper is extracted. Precious metals and other byproducts are also recovered in the process.  PASAR has expanded its smelter capacity to 720,000 mtpy of concentrates in early 2006. In May 2007, PASAR will complete a brownfield conversion from conventional starting sheet electrorefining to ISA process. Refinery capacity will be increased from 172,500 mtpy to 215,000 mtpy of coppr cathodes.

February 1, 2012 - It took an unexpected snag in the operations of an important plant, to prod temporarily out-of -job workers to try other jobs.  Around 2,000 casuals and contractual workers were affected by the closure of the Philippine Associated Smelting and Refining Corp (PASAR) in Leyte. To help the displaced workers, the local government of Isabel had been conducting job fairs for skilled workers like pipe fitters and welders to help them find jobs outside the country.  An official of the local government unit (LGU) of Isabel, Leyte has expressed concern on the stoppage of operations of the Philippine Associated Smelting and Refining Corp. (PASAR) located inside the Leyte Industrial Development Authority in Isabel, Leyte.  It might be remembered that PASAR management temporarily shut-down its operations when its acid plant, where the electrostatic precipitator (EP) was located, burned down at around six o’clock in the morning of January 2. The EP is vital to the operations of the plant.  Allan Borinaga, senior administrative assistant to Isabel town Mayor Saturnino Medina expressed concern on the effect of the stoppage of operations saying that the town stands to lose in income as PASAR is the top source of income generation for the municipality.  Borinaga disclosed that with the stoppage PASAR management is seeking for a moratorium of sales tax payment. The LGU would suffer a big lose to as much as P 5 million every quarter from the non-payment of sales tax alone. He also said that the income received from PASAR is used by the LGU to defray the costs for its various programs and projects for the people.

January 9, 2012 - The Philippine Associated Smelting and Refining Corp. (Pasar), the only copper smelter and refinery in the country, has stopped its operations after a fire damaged its acid plant located within the Leyte Industrial Development Estate in Isabel, Leyte.  But Pasar management has assured its 800 regular employees and 1,500 service contractors will continue to report to work and will be paid although will be temporarily assigned to different tasks.  “We foresee a challenging time ahead due to the shutdown as we repair and rebuild the damaged portions of the acid plant. We are not yet sure how long this will take, but we are assessing what needs to be done in rebuilding the EP (electrostatic precipitator), to keep the shutdown as short as possible and to restart operating at full speed as soon as possible,” Pasar president Sias H. Els said.  Els added that Pasar is doing everything in exploring all the possible options and actions to recover immediately.  “Everyone will therefore continue reporting for work as usual until further notice, although perhaps with different work assignments, and everyone will get paid. We need to use the opportunity to do housekeeping and properly clean and do repairs where needed,” Els said.  Pasar’s acid plant, where the EP was located, was burned down in the morning of January 2. It took five hours for fire fighters to contain the fire.  The extent of the fire was severe but no fatalities and no direct injuries were reported. Minor burns were suffered by an employee, Orland Matuguina, who was involved in the fire fighting operations.  Fire probers initially estimated the damage at P15 million. But according to J. Paul Tan, Pasar’s assistant vice-president for industrial and community relations department, the damage could reach as $1 million.  “We could not immediately determine the actual damage. Our assessment continues. The acid plant alone costs a little over $1 million. But right now we are sending people to China and Japan to find for replacements of the burned machineries. We need it custom-built and that is why it will take us sometime to resume operations,” Tan said.   Tan admitted that Pasar’s operation is “not normal” and has affected the production of electrolytic copper cathode and refined copper anode where markets are very high in China, Korea, Taiwan, Vietnam, Thailand, Malaysia, Indonesia and Japan.  Tan said the company wants to restart operations by February.  “What happened was an integral risk of smelting. With the full support of our shareholders, we will overcome this challenge,” Tan said.  Tan added the company could continue operating but electronic precipitators is vital to its anti-pollution measures.
