Anti-mining advocates here greeted with resistance the Department of National Defense's plan to deploy soldiers to foreign-backed mining projects for protection from communist attacks. Eliezer S. Billanes, chair of the South Cotabato, North Cotabato, Sultan Kudarat, Sarangani and Davao Del Sur Alliance for Genuine Development, warned that militarization of mining areas “…will result to displacement of indigenous peoples and more human rights violations"…Foreign-backed mining companies in the country are facing threats from the New People's Army (NPA) rebels, who have been known asking "revolutionary taxes" from big companies. The authorities labeled this act of the rebels as "extortion". [refers to Sagittarius Mines, Xstrata, Indophil]
