Contravention of these policies and procedures ill be subject to in$uiry and%or disciplinaryaction by management and, if relevant, to referral to the &epartment of Mines or other authorities of the "epublic of the Philippines.

The personal conduct of employees is a factor in maintaining safe mining operations, thisdocument relates to the or# place operations in or#ing hours. Greenstone resourcesCorporation e'pects satisfactory personal conduct of all its employees in all areas of their operations at all times.

This document ill also form part of the Project Management Plan for any Open Pitactivities, and be a basis of obligations by contractors on any Greenstone site.

3 SAFETY AT WORK

(our safety at or# is, obviously, important to you, and also to Greenstone "esourcesCorporation. )afety is also a team effort. (ou are dependent on other people*s standards.+oever, remember that safety is your responsibility.

The &uty of Care in the or#place is a far-reaching responsibility. It means thatManagement and you, the individual, have a duty to ensure that the safety of other people,or#-mates and the public is not at ris# by your activities or by failure to act upon identifiedhaards.

!lays report accidents, incidents, near misses or hatever seems to you to be a haardto your supervisor, as soon as possible. /liminating haards is a major step in ensuring

every-ones safety.

&o not attempt jobs that you are unsure that you can do safely. !s# your supervisor for instruction or training for any such job. (our supervisor ill ensure that you are not e'posedto unnecessary haards and that you are using a safe or#ing practice.

3.1 SAFETY PHILOSOPHY

• )afety is your responsibility.

• !ll injuries and accidents are reportable.

•

!ll employees are responsible for creating a safe or#ing place.• 0or#ing in a safe and responsible manner is a condition of your employment.



• !ll haardous e'posures can be eliminated or guarded against.

3.2 BASIC SAFETY RULES

a1 2se the correct Personal Protective /$uipment 3PP/1 for the job.b1 Thin# )afety, loo# for the potential haards and report it.

c1 Observe all arning signs and &anger Tags.

d1 "eport all accidents, injuries and haards immediately.

e1 Chec# your place of or# at the start of your shift for any haards.

f1 Ma#e regular 456-degree chec#s of your or# area, conditions can, and do, change.

g1 7eep all safety guards in place.

h1 Inform your relief shift supervisor and or# mates of any haard potential or situation.

i1 )tart your shift in a fit mental and physical state. j1 +orseplay in the or#place ill not be tolerated, as it leads to accidents.



4. INCIDENT / ACCIDENT REPORTING

It is a re$uirement of Greenstone that !88 incidents, near misses, accidents and injuries areto be reported to your )upervisor as soon as possible BEFORE THE END OF THE SHIFT inhich they occur and the Company INCIDENT / ACCIDENT REPORT is to be filled out.The Greenstone )afety and +ealth Officer is to be notified as soon as possible and a copy of the filled out report should be forarded to him. !dditionally all Incidents and !ccidents areto be reported to Client )ite "epresentative as soon as possible.

Incidents are to be reported so that a problem can be rectified

before it turns into an accident causing injury and/or damage.

!ll injuries are to be reported to the )upervisor regardless of the minority. Minor injuries candeteriorate at a later stage and Compensation Claims ca!" be processed unless the injuryhas been reported.

(ou should not attend a &octor for a or# place injury ithout first reporting it.

• There must be a spotter for the person ho ill retrieve the sample.

• )potting is to be the only role of this person . Only one drill-rig andsampler is to be superintended by that spotter. The spotter must be

e'perienced and competent in sampling activities at Plutonic to beacceptable in this role.

• The spotter ill have a @-ay radio tuned to a designated channel for or# in a stop area and an audible signaling device. !n air-horn is arecommended device.

• In the event that the spotter detects any ground movement, he % she shallimmediately notify the driller and sampler, by radio and % or audiblesignaling device to move to a designated safe location

• It is $uic#er and safer to ta#e a bag sample from the splitter than a collar sample. 2nder direction from the spotter the sampler may retrieve thebag and $uic#ly attach any additional bag. The usual safety precautions

ith regard to aiting for the rig to poer-don etc. still apply, of course.• Clear communication beteen all three parties is essential hen these

samples are being ta#en. These activities must only occur during daylighthours.

of lighting the fuse, must elapse before any person approaches the shot to inspectthe misfire.

If the misfire is found during the post blast inspection then, for a safety fuse shot thearea must be vacated until the half-hour period from lighting the fuse has elapsed.Only then can the remainder of the shot be inspected and remedial action be ta#enith the misfire.

Topsoil and vegetable matter ill be retained by carefully scraping or doing off thedump area and stoc#piling beside the edge of the proposed dump. /'cessivetramming and handling of the topsoil is to be avoided to save costs as ell aspreserving the seeds and organic material. Typically, the topsoil ill be pushed or dumped into indros on three of the four sides of the dump as efficiently aspossible. Once the first batter is complete, or a sufficient length and area iscomplete, most of the topsoil in indros ill be doed bac# up the slope. !s the area of the dump ill be greater than the original base area cleared, thereplaced topsoil ill not be as deep as it as originally or ill need to be replaced instrips to enable re-groth over the full height of the dump and hopefully result ineventual spreading and joining of the strips. 0here ade$uate topsoil e'ists or is

available nearby, loads ill be tipped at the top of the batter and doed or gradeddon the slope.

5<.3 F!#) !( D$# Ba""'%

If the aste material is placed carefully during construction of the dump there needbe very little e'tra doing or dump maintenance than for the previous method of simply establishing a tiphead and doing off.The first layer of aste ill be end-dumped as normal, leaving at least one metrebeteen the toe of the dumped loads and the inside toe of the topsoil indro3depending on truc# sie1. :rom the perimeter of the dump, a strip up to 4> metreside in from the edge for three of the four sides 3again depending on truc# sie andthe dump area1 ill then be doed flat sufficiently for the truc#s to again end tip



another layer on top, this time stepping in far enough to allo for the re$uired finalbatter angle 3see diagram1.This procedure is then repeated another one or to times ith the last layer not beingdoed cuff, resulting in a reasonably compact outer edge of the dump at least tothirds the height to the first berm. 0here practicable, aste from near surface is tobe used if suitable, as it normally ill be less al#aline than deeper don and,therefore, better able to support re-groth.<ormally, the fourth side of the dump ill be used as a re-sample area and tostoc#pile road sheeting material as ell as providing room for the permanent rampand probably a temporary ramp to construct the above terraces.

5<.4 C'"a* T)-'a+

Once the three sides have been terraced as high as practicable, a conventionaltiphead as high as the first designed berm ill be established from the main dumpaccess ramp so the centre of the horseshoe can then be bac#filled across the fullremaining dump idth. &uring this in-filling period, spare doing capacity ill be

used to form the final dump bitter slopes behind the advancing tiphead and to replacetopsoil.

Once the bottom lift of the dump is filled in, the ne't lift ill be constructed in thesame ay after tipping and spreading any topsoil at the top of the first lift and leavingthe re$uired berm idth. The berm ill be graded % doed so as to slope into thedump and leave a small indro near the outside edge. This is because in aridareas the aim is to hold any rain ater on the top of the dump 3hich ill slope gentlyinto the centre hen completed1 or on the berms, not to encourage run-off hichcould cause erosion of the dump aid provide less ater to encourage re-groth.
