MACA Interquip Appointed to Advance Metallurgical Test
Perth, April 12, 2022 AEST (ABN Newswire) - Western Australian focused gold exploration and development company, Rox Resources Limited (
ASX:RXL), in conjunction with its joint venture partner Venus Metals Corporation Limited (ASX:VMC) is pleased to announce the appointment of MACA Interquip to conduct the next round of metallurgical testwork (to feasibility level) on the Youanmi Deeps and Near Surface Resources, located within the OYG JV area (Rox 70% and Manager, VMC 30%).
MACA Interquip have also been engaged to produce scoping level study design and costing for various processing plant options under consideration, with a view to recommend a process to be incorporated into the mine feasibility study.
Rox Managing Director Alex Passmore commented:
"2021 was a successful year with respect to completing scoping level metallurgical testwork on the Youanmi Underground (Deeps) Resource (ASX release 6 October 2021, and ASX release 23 December 2021) proving that the Youanmi sulphide mineralisation can achieve very high extraction rates through various methods. Mine planning has also progressed to a stage where we now understand that free milling pit feed will likely make up 60 to 70 percent of the total feed tonnes allowing larger processing plant options to be considered and reducing the percentage of sulphide material in the total feed. Our plan includes a dual-purpose plant for oxide and sulphide feed material, which is now included in the scope for processing plant design and costing."
Key understandings from 2021 Deeps Resource metallurgical testwork are presented in Figure 1 below. The testwork provides confidence that a modest portion of gold in mineralisation resides in arsenopyrite, and pyrite minerals. More detailed metallurgical testwork has commenced on various mineralisation domains.
Dual-purpose Processing Plant
Conceptual Life of Mine (LOM) mine plans have so far indicated that
- around 60% to 70% of mill feed tonnes in the LOM will be sourced from open pits which are made up of oxide material from which gold can be extracted efficiently via the standard and widely used CIL extraction process.
- the remaining 30% to 40% of mill feed tonnes in the LOM will be sourced from underground sulphide materials which can be simply extracted via use of a conventional flotation circuit producing a gold concentrate achieving Au metal extraction rates of over 91% (refer ASX announcements 6 October 2021 and 23 December 2021)
