This technical report presents mineral processing and recovery methods for the Higginsville-Beta Hunt operation in the Eastern Goldfields of Western Australia, as of December 31, 2020.
Report context
This NI 43-101 technical report is dated January 29, 2021, with an effective date of December 31, 2020, prepared for Karora Resources Inc. The operation comprises the Beta Hunt mine, the Higginsville Gold Operations, and the Mt Henry Project, all located in the Eastern Goldfields of Western Australia.
Processing route
Process description
The processing facility at the Higginsville Gold Operation employs a conventional gold recovery circuit comprising crushing, grinding, gravity and intensive cyanidation, leaching and adsorption, carbon stripping, electro-winning, refining, and carbon regeneration. Tailings disposal completes the process.
Crushing and grinding
The process begins with a crushing stage followed by grinding. No further flowsheet details regarding specific crusher types, grinding mill dimensions, or circuit configurations are provided in this section.
Gravity and intensive cyanidation
A gravity concentration circuit is incorporated, with intensive cyanidation applied to gravity concentrates. No further performance data or design specifications are reported.
Leaching and adsorption
The ground material proceeds to leaching and adsorption stages for gold recovery from solution.
Carbon stripping, electro-winning, refining, and carbon regeneration
Loaded carbon is stripped of gold, which is then recovered via electro-winning and refined. Carbon is regenerated for reuse in the adsorption circuit.
Tailings disposal
Tailings from the process are disposed of to a tailings storage facility. No design or performance details for the tailings storage facility are provided.
Plant services
Supporting plant services are included in the process facility but are not described in detail.
