Tri Origin is committed to the effective environmental management of all its sites. This Code provides for the mitigation of environmental impacts associated with exploration activities.

Before commencement of an exploration program, planning should ensure that:

• Landowners, relevant government departments and other constituency interests are formally notified of the granting of the exploration lease, and, where appropriate, are consulted prior to commencement of fieldwork;
• All project personnel are aware of relevant legislative requirements;
• Unnecessary clearing is avoided and disturbance to natural drainage lines is minimised;
• Potential waste and ore is adequately characterised with regard to key geochemical and physical properties;
• The spread of weeds is avoided;
• Sites with archaeological and historic values are managed appropriately; and
• Rare plant and animal species are managed appropriately.

During exploration, site management must ensure that:

• Compliance is achieved with all operating conditions;
• Appropriate erosion control measures are implemented;
• Oil, fuel, drilling chemicals and other chemicals are not lost to the environment;
• Where practicable, topsoil removed during earthworks is stockpiled and respread during rehabilitation; and
• Rehabilitation is implemented progressively.

At the completion of work, site management must ensure that:

• Auger holes, pits and costeans are backfilled;
• Drill holes are sub-surface capped and sealed;
• All rubbish is buried or removed; and
• Drill sumps are pumped out, dried and backfilled.

The implementation of this Code is the direct responsibility of the geologist managing the exploration program.
