  14A. DEFECTS LIABILITY
 14A.1
    
    In this Contract the Defects Liability Period means the period commencing on
the date agreed in writing between the parties as being the date upon which the Works
achieved Mechanical Completion or, where the parties are unable to agree, the date
determined pursuant to the dispute resolution procedures in clause 29 of this Contract
as the date upon which the Works achieved Mechanical Completion, and expiring on the
date 12 months after the date of Mechanical Completion.14A.2
    
    At any time prior to the expiry of the Defects Liability Period, the Company or
the Companys Representative may in writing require the Contractor, at the cost of the
Contractor, to rectify within no less than 14 days (except in the case of an emergency
or situation of imminent peril, in which case the Contractor will be required to
immediately rectify) any omission or defect in the Works existing at the commencement of
the Defects Liability Period or which becomes apparent prior to the expiration of the
Defects Liability Period, except where the omission or defect is insubstantial or
trivial. The Company will immediately (within reasonable limits) notify the Contractor
of any mechanical defects which may affect the integrity of the equipment. If the
Contractor has not rectified the identified (but not insubstantial or trivial) omission
or defect (as the case may be) within the time required by the Company, then the Company
may itself rectify, or engage others on its behalf to rectify, the defect or omission
and the reasonable costs of doing so will be the responsibility of the Contractor.14A.3
    
    Upon the rectification of any defect or omission, there will be no new Defects
Liability Period created in respect of the rectified Works unless otherwise agreed in
writing between the parties. For the avoidance of doubt the rectified Works remain
subject to the initial Defects Liability Period.

ItemEnvironment & CommunityGekko and all contractors under its control will at all times comply with the BGF Standard
Environmental Conditions as defined in Schedule 2.Any situations which could have potential impacts on the environment or community are to be
discussed and approved by BGF prior to the commencement of any such activity.Occupational Health & SafetyGekko and all contractors under its control will comply at all times with the elements of the
BGF Safety Management SystemGekko will be responsible for the safety management of all site activities  supervision,
inductions, hazard identification and reporting, incident reporting and investigation, safety
auditing, toolbox meetings, isolations and permitting and workplace housekeeping standardsAll persons will undertake a BGF site induction and construction induction prior to
commencing work4
    
    Project Scope  EquipmentGekkos scope of work involves the addition of the following major items of equipment to the
existing processing plant circuit:Grinding Mill and CycloneThe purpose of this equipment is to grind the current Spinner tails, Wilfley table tails, and/or
stockpiled Spinner tails (at a maximum rate of 3.75 tonnes per hour) to 80 percent less than 130
microns, thus enabling a high level of gold liberation in subsequent leaching.In Line Leaching Reactor (ILR10000CA).To enable the leaching of gold from the ground concentrate. This unit and the subsequent
equipment is designed to leach up to 49% of the gold fed to the processing plant at Design
Criteria feed rate and head grade, which are 75t/h and 8.5g/t respectively.Resin-in-column (RIC) module.The purpose of this equipment is to upgrade the gold concentration in the ILR discharge solution,
thus increasing the efficiency of the Electrowinning process.Electrowinning Cell and RectifierTo recover gold from the RIC strip solution into a form that can be readily smelted into
bars. Smelting will be done using the existing facilities.Cyanide destruction facilities.This part of the plant will use the INCO process to ensure that cyanide levels in the
final

itemplant tailings are in compliance with environmental requirements. It is proposed
to chemically reduce the cyanide content in the leach tails to 50ppm WAD cyanide, then to
mix these tailings with the Gravity Plant tailings in order to produce a combined plant
tailing WAD cyanide content of less than 5ppm.Reagent storage, mixing and dosing facilities.Several chemical reagents will be required to support the leaching and cyanide destruction
modules. Facilities will be installed to safely mix, store and distribute these reagents.5
