Mining Plan

The mining lease is transferred to the operating entity. This involve an application and what is termed a ‘mining plan’ which describes the activity and includes a quarrying plan to show how the resource will be fully developed in an efficient manner over time

The operators have a comprehensive mining management plan approved by and under lease permit condition requirements, flora and fauna survey conducted and continue to be monitored to ensure that the quarry is low risk to disturbing any threatened flora, fauna or communities.

The Operator has constructed sediment retention basin to prevent uncontrolled runoff from the quarry entering the receiving environment.

Weed incursion risks are monitored and controlled for ongoing treatment by introducing weed and disease hygiene management measures.

Specialised Consulting Contractors are commissioned by Highland Mineral Resources to conduct monitoring and risk assessment for weeds and Phytophthora cinnamomi (Phytophthora) at the Arthurs Lake Quarry and adjacent internal property areas.

Monitoring for weed species entering and or present on-site, also carry out mitigation control methods and report any necessary implementation actions required, and evaluates the likelihood of Phytophthora occurring. monitoring protocols for early detection and recommends management actions to prevent or limit the pathogen’s spread if detected and ongoing weed control for quarrying processing and cartage equipment hygiene measures.

The Operator had blasting noise modelling undertaken that shows no existing proximity dwellings will experience air-blast overpressure or ground vibration in excess of acceptable limits.

A mechanical noise study found that under worst case scenario condition requirements of the Quarry Code of Practice with regard to mechanical noise will be within the required limits.

The existing surrounding eucalypt forest and woodland that screens the quarry from Arthurs Lake Road are supplemented with an additional planting to ensure that the quarry remains concealed from the direction of Arthurs Lake.

Arthurs Lake Quarry can continue to operate at an annual production rate without any adverse effects on the receiving environmental or the local community.

Mining Planning Summary

1) Initial development (+/- 25 k BCM)

  • Formalise dewatering sump at southwest corner of existing low area.
  • Advance 1135 m bench northward towards current northern face leaving 5 m wide bench.
  • Construct sediment traps in the form of dam embankment
  • Construct spillway around embankment in natural ground and install rock lining to protect against scouring.

2) Future development (+/- 100 k BCM)

  • Advance top bench (1155 m) towards northwest boundary, leaving 10 m offset. Square off top face and prepare 5 m wide section of top bench against face for progressive rehabilitation.
  • Advance subsequent benches 1145 m and 1135 m leaving 5 m wide benches.

3) Ultimate development (+/- 100 k BCM)

  • Rehabilitate top bench on perimeter of quarry development.
  • Instal new dewatering sump at the edge of the access road.
  • Extract existing floor of the quarry grading down to 1125 m level.
  • Advance floor excavation towards west, north and east faces leaving 5 m wide bench for future rehabilitation.
