Mining must not be conducted in Rapu-Rapu for the following reasons:
a) Rapu-rapu is an island ecosystem with
steep slope;
b) It is characterized by a Type II climate - no dry season with very pronounced wet period from November to January (PAGASA Corona classification);
c) It is located along typhoon path; and
d) Its massive iron sulfide rocks are capable of generating sulfuric acid.
These geophysico-chemical conditions are the reasons why, within only four months of operation, Lafayette mining caused two cyanide spills and fish-kills in October 11 and 31, 2005.
Apparently, it also brought about fish-kills in the adjacent province of Sorsogon.

4. Effects of the cyanide spill and siltation of the sea
- fish-kill due to cyanide
- fish-kill due to silt that injures the gills of fishes as a
result of abrasive action of silt to gill tissues.
- loss of livelihood in fishery in the island and adjacent
municipalities at the eastern coast of Sorsogon
- various ailments experience by the people, possibly
due to the spill incident
- toxic heavy metal accumulation in aquatic
organisms and people that would cause a variety of
illnesses
5. Objectives of the study
To assess the damage to the biophysico-chemical condition
of the eastern portion of the island of Rapu-Rapu affected by
the cyanide spill and fish-kill from mining activities.
Specifically, the study intended to:
a) determine the level of heavy metal pollution in the
water (river) in and adjacent to the mining site;
b) determine the level of heavy metals adsorbed by
soil/sediments of the affected river and seashore; and
c) ascertain the impacts of heavy metals on biological
indicators.

19. Summary of heavy metal pollution of water and
sediments
a) contamination of water in Sites 1 and 2 with high levels of
cadmium, copper and zinc
b) contamination of riverbank sediments with high levels of
arsenic, cadmium and copper, with the latter exceedingly high
particularly at the shore; also Hollowstone Creek with copper
c) Chromium was detected highest in Site 3 but below the
standards at the upstream and slightly higher than the
standard at the outlet.
d) Copper is also high in water and in sediments at the Upper
Tailings Pond which is located inside the Mine.

36. Impacts to Rapu-Rapu and Sorsogon
1. Fishkills - Continued fishkills (Malasugi, shark, squid,
octopus, etc) in Rapu-Rapu in December and January
after heavy rains and in some northern and part of
western coast of Sorsogon
2. Loss of livelihood in fishing - People from the area and
adjacent areas, i.e. Legazpi and Sorsogon Cities, etc.are
afraid to buy fish coming from the affected coastal
barangays
3. Tourism as a livelihood is low - Loss of potential tourists
4. Possible health effects to several people who felt some
forms of illnesses during the fishkill
5. Break-up of families and loss of stability
37. Impacts to the ecosystem
1. Aside from Pagcolbon River, three (3) additional creeks
became acidic due to Acid Mine Drainage, which was
facilitated by the mining operations. These are Alma
Creek, Ungay Creek and Hollowstone Creek.
2. The dispersion of heavy metals into the surroundings
affected the productivity of plants (terrestrial and
marine) by destroying the capacity of their chloroplasts
to produce food
3. Cyanide solution aggravated heavy metal pollution in
the affected river/creeks and marine habitats and caused
fish-kills
38. 4. Fishing suffered from destruction of the sources such as
the seagrass beds and coral reefs
5. Huge amounts of tailings resulting from the mining
operation continue to generate AMD and are also
threats to human safety as well as to the terrestrial and
marine habitats specially during the rainy season.
6. The diseases and other ailments experienced by the local
communities in Binosauan and in the municipality of Prieto
Diaz indicate probable cyanide and heavy metal
contamination from mine wastes that were brought to their
places due to proximity or through surface waves driven by
the northeast monsoon. Such experiences happened only
during the cyanide spill and fish-kills.
39. Massive iron sulfide rocks with acid-generating
capacity or Acid Mine Drainage (AMD)
Acid mine drainage (AMD)
AMD occurs in iron sulfide rocks that are exposed to
oxygen and water and cause the following reaction:
2FeS2 + 702 + 2H20 = 2H2SO4 + 2FeSO4
H2SO4 = sulfuric acid
FeSO4 = red orange iron sulfate precipitate
that coats rocks and sediments
40. Heavy metals released from Tailings dump due to acid
mine drainage (AMD)
Tailings dump of the Formation of AMD in thewith no AMD (Dec
mine Rock barrier same

42. Conclusion
It is the huge amount of tailings, waste rocks and overburden
soil generated by the mining operation that caused the fish-kills
It is the introduction of cyanide that facilitated the released
of toxic heavy metals that were released into the surroundings
and polluted the surroundings of the mine, the associated
creeks, and the adjacent sea that also caused the fish-kills
It is the natural capacity of the land for generating acid
through the process of Acid Mine Drainage (AMD) that
worsened pollution. The geophysico-chemical conditions of
the island simply facilitated this process
43. It is the rainy climate, the steep slope and the typhoons that
regularly visited the area that resulted in a wider dispersion of
the toxic pollutants and the loosened silt in the eastern part of
the island of Rapu-Rapu and the coastal areas of Sorsogon
It is not the length of time of exposure to the toxic metals that
destroyed the productive capacity of the land and water but the
level of toxic pollution that mining operation brings to the
environment that caused the damage
Thus, it is the mining operations of Lafayette Philippines, Inc.
that caused the cyanide spills and fish-kills that affected
Rapu-Rapu and the coastal areas of the province of Sorsogon
and destroyed the ecosystem of the land and sea that will
persist for a long, long time. AMD will continue for hundreds
of years.
44. Recommendation
Mining must be stopped. The government must
cancel the permits associated with the issuance of
an ECC to Lafayette Philippines, Inc.
No mining must ever be allowed in Rapu-Rapu again.
The government must rehabilitate the degraded
ecosystems, especially the newly formed acidic
creek in Malobago, Pagcolbon and Binosauan
45. Expert assistance to the health problems
experienced by the local people must be provided
Government agencies responsible for evaluating
mining projects and those giving permits, must be
given more comprehensive trainings for assessing
pollution generated by mining operations and for
rehabilitating degraded areas especially in places
with acid generating capacity.
46. There are alternatives to mining metals because
metals can be recycled. There is no need to open up
new areas in order to extract the metals for the needs
of our country.
Rich nations have minerals of their own. Why
destroy the beautiful land with high biodiversity, the
natural wealth that God gave us?
The process of obtaining these materials makes
people poor and the marginalized, poorer.
47. Mining in Rapu-Rapu must be stopped.
Lafayette mine must be closed; its various
permits in connection with, and the ECC
must be cancelled.
Let us all remember that God created
minerals and metals to support our
NEEDS, and not our GREED.
48. Only our love for God, for our
Country, and for our people can
free us from this misery.
