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.

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

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
![Page 13: Agham slides report_for_dp[1]](https://reader033.vdocuments.net/reader033/viewer/2022050818/55c47b52bb61eb1c688b46fe/html5/thumbnails/13.jpg)
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

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

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
![Page 22: Agham slides report_for_dp[1]](https://reader033.vdocuments.net/reader033/viewer/2022050818/55c47b52bb61eb1c688b46fe/html5/thumbnails/22.jpg)
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
![Page 23: Agham slides report_for_dp[1]](https://reader033.vdocuments.net/reader033/viewer/2022050818/55c47b52bb61eb1c688b46fe/html5/thumbnails/23.jpg)
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
![Page 24: Agham slides report_for_dp[1]](https://reader033.vdocuments.net/reader033/viewer/2022050818/55c47b52bb61eb1c688b46fe/html5/thumbnails/24.jpg)
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.

Conclusions
3. There are confirmed adverse impacts to
the civil, economic, social and cultural
rights
![Page 26: Agham slides report_for_dp[1]](https://reader033.vdocuments.net/reader033/viewer/2022050818/55c47b52bb61eb1c688b46fe/html5/thumbnails/26.jpg)
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
![Page 27: Agham slides report_for_dp[1]](https://reader033.vdocuments.net/reader033/viewer/2022050818/55c47b52bb61eb1c688b46fe/html5/thumbnails/27.jpg)
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
