Xstrata continues mine studies in Philippines

June 11, 2010

“A unit of Xstrata said on Friday it will proceed with public discussions and technical studies on its $5.2 billion copper-gold project in southern Philippines despite a looming local ban on the venture.

State agency Mines and Geosciences Bureau (MGB) said it may question the ban with the courts as a last resort, adding the measure could hinder investment in the mining sector.

Manila has ambitious plans to develop the mining sector from a moribund state by attracting billions of dollars of foreign investment.

The Tampakan mine, considered Southeast Asia’s largest undeveloped copper-gold prospect, was opposed by local residents who feared the open pit mining method to be used by Xstrata’s Philippine affiliate Sagittarius Mines Inc would pollute a major river irrigating farms. Mine production is set to start in 2016.”

  • Feasibility studies indicated the Tampakan deposit could sustain an annual average copper production of 340,000 tonnes per annum and 350,000 ounces per annum of gold, based on a 20 year operation (source: Infomine.com)
  • Local government at Tampakan has banned open pit mining at the Tampakan deposit. Fears are that the large scale mining operation will pollute the local river on which water many farmers are dependent.


  • Local government might be overruled by national government. However, Xstrata will need to prove to the locals that the open pit mining operation will not lead to pollution of the river in order to change public opinion.
  • Proving impact of mining on groundwater and river and influencing this impact is typically very difficult, as groundwater aquifers are very hard to map.
  • Underground mining, which is favoured by the local government, reduces the need for lowering the groundwater level, but pollution risk from processing and waste/tailings is the same as with open pit mining.
