- Dizon Copper-Silver Mines, Inc. is a Philippine-based natural resources and general contracting enterprise primarily engaged in the exploration, acquisition, development, and operation of mineral properties, as well as infrastructure and civil construction services. Founded on August 18, 1966, and headquartered in Mandaluyong City, Metro Manila, Philippines, the company operates across three principal business segments: Mining and Mineral Exploration, Infrastructure and General Contracting, and Real Estate and Asset Management. The company's core product and service portfolio encompasses the exploration, extraction, and evaluation of precious and base metal deposits, specifically copper, gold, and silver concentrates; care, maintenance, and environmental monitoring of tailings storage facilities; general construction and civil engineering contracting, including the development of roads, bridges, dams, piers, and commercial buildings; and the management, leasing, and development of industrial and commercial real estate properties, including holdings in Valenzuela City. Through its subsidiary, Redridge Resources Corporation, the company maintains mineral claims and exploration rights across the Philippines. In recent developments, Dizon Copper-Silver Mines has strategically refocused its operational priorities on mine site remediation, asset rationalization, and the economic recovery of secondary resources. The company's board approved a three-year, PHP 25.5 million rehabilitation initiative for the Bayarong Tailings Dam in San Marcelino, Zambales, aimed at stabilizing legacy containment structures and executing tailings reprocessing operations to extract residual gold, silver, and copper from an estimated 47 million cubic meters of mineralized material. Concurrently, the company has pursued balance sheet restructuring through the divestment of non-core properties, including the negotiated sale of the Port Dizon maritime facility in Subic, Zambales, while actively seeking joint venture partners and regulatory clearances to support commercial tailings re-treatment and expand into broader civil infrastructure contracting across the domestic Philippine market.
