Silver Lake’s future secured with Deflector approval

Silver Lake Resources continues to develop the Deflector South West corridor for its Deflector gold-copper project in Western Australia as part of a plan to extend the mine’s life.

The company board has approved the DSW access, development and production, which it said would enhance the returns from the carbon-in-pulp (CIP) circuit at the Deflector processing plant.

The ore at the Deflector project is located in a series of structurally controlled lodes. The DSW lodes are adjacent to the existing underground mine and this development will support a longer mine life, higher margin operation and enhance returns from the processing plant.

These lodes host a higher quality gold and copper tenor and account for 35 per cent of the Deflector ore reserve and 30 per cent of its mineral resource.

Surface works to prepare the decline access are scheduled to begin next month and further development is expected to commence by the end of the second quarter of the 2021 financial year.

Ore development from the upper levels of the South West lodes contributing to the plant feed is planned for the first quarter of the 2022 financial year, with stoping to start in the second half.

“Silver Lake will significantly reduce ore drive profiles within the South West lodes when compared with past and existing practices adopted within the established Deflector mine,” the company stated.

“Smaller drive profiles reduce waste dilution, increase grades of ore won from development and liberates mill capacity which captures the full value of the higher grade feed and increase in gold recovery following the addition of the carbon-in-pulp (CIP) circuit to the Deflector processing plant.

“The current ore reserve and continued strong exploration results demonstrate the continuity of the Deflector South West lodes and support the investment decision to establish decline access and associated mine infrastructure form the existing open pit.”

Once works are completed, Silver Lake will enjoy more flexible operations and will be able to optimise the Deflector mill feed grade from the 2022 financial year.

Defining further South West lodes and potential Deflector repeats is one of the company’s highest priorities for exploration and it is conveniently located alongside existing mine, services and processing infrastructure.
