HEXAT MINING Inc.,An accomplishment in

Ecology and Business Management



Introduction



In the year of 1990’s, many mining corporation had develop

and functionalize for the reason that it is where small scale

of mining operation became period of making precious and

fine gold and silver. In this period (1990), it is where theHEXAT mining name had created. On October 1, 1994, the

business group under the leadership of Mr. Noe Taojo took

a new name of HEXAT mining.

On July of 1995, the group formed the umbrella

organization-HEXAT holdings, Inc. which was registered

with the Securities and Exchange Commission (SEC) on

July 26, 1995. Right of the same year October 25, 1995 it

was registered with SEC. many developers of the company

had invested much money and effort to develop and expand

the said corporation. The HEXAT Corporation is part of

province of Davao del Norte, in Barangay Magdum, Tagum



I-Industry Study

The HEXAT Mining Corporation has

evidently secured EnvironmentalCompliance Certificate (ECC), the Housing

and Land Use Regulatory Board;

application to construct Waste Water Treatment Works and Processors Permit, the

ECC, is a requisite; this report follows the

annotated out line provided by

Environmental Management Bureau (EMB)

of Department of Environment and Natural

Recourses (DENR).



II-Project Description

A. Basic Project Information

Project Name : HEXAT Gold Processing

Address : Km. 61, Barangay Magdum, Tagum City,

Davao del Norte

Type of Project : Mineral ProcessingProject Proponent : HEXAT MINING

CORPORATION

Contact Person : Mr. Ferdinand Galang Manager



B. Project Location

The milling plant of Hexat Mining

Corporation is located at Km. 61, BarangayMagdum, Tagum City, Davao del Norte.

The plant site can be reached by vehicle via

the paved Daang Maharlika Highway and61 km from Davao City.



C. Project Rationale

The project is highly operational it is the

gathering of raw mineral material (like naturalstones/rocks) which produces ores, metals,

minerals and hydrocarbon. Acids and chemicals

are producing in other forms of elements. The project is using heavy and bid machines and

useful pure metal equipments for grinding,

mining, milling, concentrating, converting,

transporting, manufacturing, buying and selling

of different product produces.



D. Alternatives

Another substitute process that can be utilize

in order to recover a gold but not usingcyanide as the main source for hydrometallurgical recovery for gold:Chlorination, Chlorination was used two

centuries ago before the use of cyanidation.Chlorine was first used to recover gold fromresidues from amalgamation. Later, was usedin big operations in the American and

Australian gold fields. At the present time,chlorination for gold recovery is used onextremely small scale where gold is a minor constituent with other precious metals.



E. Description of Project Phases

Pre-construction/Operation Phase In Pre- construction, first on the list is clearing of a grassy siteremoving of different forms of grasses (cogon) and wild plants.Secondly is the leveling of the land take assure that the land isevenly plane in constructing buildings, offices, canteen,

laboratories and tanks and tunnels. Thirdly, is creating a boardingfence where estimated location is highly covered in the territory.

Construction Phase

The construction phase involved civil, mechanical and electricalworks. Civil works were construction of buildings, drainage

system and the tailings ponds. Mechanical were the installationvarious CIP tanks and commissioning of equipment related togold recovery from the ore. Electrical works were installation of wirings and other electrical accessories.



Operational Phase

The processes are shown which can picture out the flow of designed and chart of the study. These are the following

procedures in their operational phase.

Washing

The materials (rocks) are washed using the water toremove the mud and fine dirt.

Crushing The materials are prepared for crushing and screening

processes and the small thin fines will come out from thescrubber then to be move transferred to the open launder

with washed water. Repulping

Some materials are transferred by pump going to thegrinding circuit and the materials are discharged by usingchute and go through a feeder and moved to crusher byusing a conveyor



Grinding

The materials like wood chips, debris, and fibers will be grind until

they will be separated by using a ballmill.

Classification The waste material will be separated.

Concentration and thickening

The materials will go through a thickener for pulp thickening.

Leaching

The pulp will be treated using cyanide solution to make sure that

the cyanide strength will be maintained at its required level. Then

the air compresses at the tanks to enhance that dissolution of the

gold with cyanide solution. Floatation

There will be floatation after the grinding sections wherein those

fine thin materials left will be re-grind again.



Adsorption

Separation of gold from final trails leaves theadsorption tank then let it flow to the pond below

the mining plant then the carbon should be removedfrom the tank, it will be placed in the vessel to bewashed.

Desorption

The carbon should be moved where the gold is tothe desorption vessel.

Electrowinning

Prepare for electrowinning process.

Carbon Regeneration

The plated steel will be removed from theelectrowinning to be smelted to be produced thegold and silver.



Gravity Concentration

The mill plant has a gravity concentration place.The plant contains elements like gold. After

producing it the circuits will be placed in the sacksfor the continuing process.

Smelting

After the amalgam has been removed from themercury then it will be put in a protected vessel.

Refining

The metallic mercury will be separated from gold.

BullionIt will be filtered to the bullion. After this processes,you must repeat it until you can produce a refinedgold.

Abandonment Phases

First, HEXAT Mining Corporation should remove all theequipments that they use during their operation. They

should carefully detach that heavy equipment (such heavymetals and steel). In removing it they should rest assurethat the equipment used is very clean like the tanks and

pipes.

Second, they should move out the materials that theyused in the structure of their company. Rests assure thatall the materials that had used in the construction should

be disengaging into acquired pieces. Such materials thathad used can be sold to any steel buyers.

Third, HEXAT should mostly take actions in detoxifyingthe ponds near Hijo River. The ponds they hadaccumulated should be free from any harmful chemicals.After the abandonment activities the company must create

plans that are helpful in relieving the site like cultivating plants for the benefiting in the environment cycle.



F. Baseline Environmental Conditions

Land

The land surface is just like a typical land

forms. The land is a hill like that where

grasses like Cogon grass and Makahiyaand tree plants like banana, Falcata and

Ipil-ipil planted in the area.

Air

The air quality is typical in rural setting.

W t



Water

HEXAT water supply is located downstream of the plant of the site. It is a creek located withestimated distance of 250 meters from the pumphouse. Hijo River is located across the street of thesite and the River is totally brown like in color, itis to the fact that some of the waste is being plunk on the river.

People As of 2007 barangay Magdum in Tagum city has8,900 populations. It has 1,780 numbers of households and 1,754 families. The people use to

engage in agriculture and other are employ indifferent field such as labor, services and professionals. Magdum is highly productive andhas big contributions in the economic stability of

the place.



G. Impact Assessment and Mitigation

Impact Identification

Air pollution is expected during the transport of raw materials from the gold rush areas to the millsites. Air pollution is responsible for major health effects. Many diseases could be caused by

air pollution without their becoming apparent for a long time. Diseases such as bronchitis, lungcancer, and heart disease may all eventuallyappear in people exposed to air pollution.

Air pollutants such as ozone, nitrogen oxides,and sulfur dioxide also have harmful effects onnatural ecosystems. But carbon dioxide is themain cause of greenhouse effects.

ACTIVITIES IMPACTS

1.) Transport of Gold Bearing Ore and

tailsAir Pollution – exposed to vehicular emission

(CO2 and dust)

2.) Receiving of ore and tails Air Pollution – CO2 and dust

Land Pollution – Cyanide from tails and

other solid wastes.

3.) Crushing and Grinding Air Pollution – CO2 and dust

Health Hazard – Accident in the siteLand Pollution – Solid wastes

4.) Leaching Health Risk – Expose to cyanide and other

chemicals

Land Pollution – Empty cyanide drums.

Air Pollution – Cyanide

Water Pollution – tails and other chemicals

5.) Carbon Washing, Stripping Health Risk – exposure to acid

6.) Electro Winning Water Pollution – spent solvent

Health Risk – exposure of chemicals



Impact Prediction

There would be air, water and noise pollution. Ore ismineralized rock containing a valued metal such as gold or copper, or other mineral substance such as coal. The ore is

then crushed into finely ground tailings for processing withvarious chemicals and Separating processes to extract the final product and it generate noise and large volume of waste water that contains traces of sodium hydroxide and cyanide.

Future Environmental Conditions without the Project Gold, copper, diamonds, and other precious metals andgemstones are important resources that are found inrainforests around the world. Extracting these naturalresources is frequently a destructive activity that damages the

rainforest ecosystem and causes problems for people livingnearby and downstream from mining operations. It wouldhave a stable and peaceful ecosystem in that particular siteregardless of human intervention such as activities by thecommunity living nearby.



Future Environmental Conditions with the Project

Mining will give unemployed people in the barangay toget at least the simplest job.

Good drainage system will be constructed in order toreduce landslide and swampy areas that could causeserious diseases like dengue to the community.

Unavoidable and Residual Impacts

For the sake of current and future generations we needto safeguard the purity and quantity of our water against irresponsible mineral development. We need toensure the best pollution prevention strategies are

employed in cases where the risks can be managed. Wealso need to recognize that in some places miningshould not be allowed to proceed because the identifiedrisks to other resources, such as water, are too great.

H. Environmental Management Plan Mitigation/Enhancement Measures/Plan (Impact/Risk)

In every project, we encounter risks and impacts. HEXAT

Mining Inc., in regards to the pollution, there are risks thatcannot be avoided (i.e. air pollution due to smoke when

separating the gold into copper and silver). The water waste

disposal treatment is treated accordingly with due processes.

They are responsible in physical, chemical, and biological

treatment. Each pollutant has its designated removal proceduresand treatments.

Mitigating measures should be implemented to help safe guard

the personnel and visitors. Examples of these are:

First aid Programs

Wearing of proper protective equipments to secure employee’s

safety and heath

Issuance of health insurance and other benefits

Social Development Program

Hexat Mining Company has conducted feeding programin Brgy. Magdum, Tagum City and they have also

implemented tree planting which is done quarterly withintheir vicinity at Pantukan, Compostela Valley is part of their social development program. Complyinggovernment

requirements and necessary documents, proper storage of documents and keep them secure,

prevent leakings and spills to avoid damage of propertiesare should be part of their contingency response plan. In

case the company will abandon their operation, thecompany will have a year to empty the place and ensurethat there wouldn’t be any harmful incidents that willoccur and especially cleaning the chemicals left that mayaffect the place in the future.



Contingency Response Plan

1. All mining within the borders of Magdum must be regulated, monitored and policed. This may

seem a monumental task but can be done withcreative methods.

2. Mining activities should be confined to specificgeographic areas over a predetermined period,

for all scales of mining.3. Mining disaster insurance should be required for all mining activity.

4. Environmental disaster planning for any given

mining project must be part of the environmentaland social impact assessment.

5. General knowledge of the technologies to beused must be made available to the regulatoryagency.



Abandonment Plan

If HEXAT make a decision to end up their operation they should set into proper pieces the

equipments they had used and clean everything inthe operation site as well as detoxifying all the ponds that they utilize.

Environmental Monitoring Action Plan

All business that involve in production is highlymonitored and screen. Of course the businessespecially the HEXAT must be monitored yearly by scrutinizing the process of making the product

and its by-product, the materials used and theequipment that consumed, the monitoring divisionalso should examine the operation and how thecompany give specialize in cleaning theequipments especially the tanks and tunnels.
