The report summarizes an environmental investigation of two large-scale mining operations in Nueva Vizcaya province. Testing found copper contamination in rivers near the Didipio mine, with copper levels exceeding safe levels for organisms. Near the Runruno mine under construction, heavy metals like copper in impacted rivers exceeded thresholds harmful to aquatic life. Both operations negatively impacted the local environment, biology, water quality, and livelihoods. The report recommends suspending mining, further assessments, ongoing monitoring, and reviewing relevant policies to address the impacts.

- 1. Environmental Investigation Mission on the Impacts of Large Scale Mining in Nueva Vizcaya Results Nueva Vzcaya November 11, 2014
- 2. Outline • Background • Methodology • Results – Biophysical characterization – Heavy metal analysis – Socio-economic impacts • Conclusion • Recommendations
- 3. Background The two mining operations in two municipalities with a total area of 17,280.84 hectares. – The Oceana Gold Philippines, Inc.: Didipio Gold Copper in Kasibu – started commercial operation in May 2013. – The FCF Minerals Corporation: Runruno Gold-Molybdenum Project currently at the construction phase, targets to start commercial operation before the end of 2014.
- 4. Objectives Evaluate the impacts of the mining operations to their immediate environment. Specifically, 1. To assess the impacts of the two mining operations on the biological, chemical and physical aspects of the riverine ecosystem 2. To correlate the impacts of the mining operations on the lives and livelihood of the communities affected

- 12. Heavy Metal Analysis: Sediments • Cu concentration is 6.5 – 7.4 times greater than the severe-effect level for benthic organisms, which is 110 mg Kg-1 Severe- effect level
- 13. Heavy Metal Analysis: water • Water from Didipio river has twice the copper conc. permitted for irrigation use and • 8x the maximum level for the survival of organisms maximum level for survival of organisms maximum level for irrigation use
- 14. Socioeconomic impacts • Use of violence and intimidation by the mining company – Employment of private securities – a military detachment is located near Barangay Dinaoyan. • Lack of compensation

- 21. Heavy Metal Analysis • Copper, Arsenic and Lead and Mercury ave. concentration in sediment from Sulong river exceeded the Severe-effect level (SEL) • SEL is an approximate level at which presence of certain contaminants severely affect the health of benthic organisms
- 22. Heavy Metal Analysis • Copper in water samples from the impact site (Sulong river) exceeded the safe level of copper for the survival of benthic organisms, which is 50 µgL-1
- 23. Socioeconomic impacts (a)forced demolitions without prior notice and with the presence of uniformed and armed men; (b)some small-scale miners lost their jobs because the mining company ordered them to stop while some are threatened to lose their jobs because of threats of land grabbing and forced demolitions; (c) some residents were also working for the mining company with 250 per day as their wage; and
- 24. Conclusions 1. There is copper contamination in both impact and confluence for Didipio mining. 2. For Brgy. Runruno, the construction stage already showed impact of mining brought about by massive soil disturbance and the removal of vegetation. Heavy metal such as copper in the impact area has exceeded those in the non-impact site.
- 25. Conclusions 3. There are confirmed adverse impacts to the civil, economic, social and cultural rights
- 26. Recommendations 1. Immediate suspension of mining operations 2. Comprehensive assessment of the impacts 3. Regular monitoring of the qualities of both sediment and water samples
- 27. Recommendations 4. Review of local and national mining, environmental, land and other policies related to the resulting impacts – Clean Water Act – Pollution Control Law – Mining Act 1995 5. Capacity-building of local communities
