Asiamet Resources Limited says it has signed a Memorandum of Understanding (MoU) with BGRIMM Technology Group (BGRIMM) in relation to the engineering and procurement of the solvent extraction and electrowinning (SX-EW) plant for the BKM copper project processing facility in Indonesia.

BGRIMM is a leading Chinese engineering, procurement and construction (EPC) group providing services to the mining industry worldwide.

The MoU will see the two companies, alongside Asiamet’s consulting engineer, NewPro Consulting & Engineering Services Pty Ltd, work on the detailed design information for all equipment packages that BGRIMM has provided cost estimates for as part of the current BKM copper project feasibility study update.

BGRIMM will also complete a detailed cost estimate for an EPC Technical Supervision scope of work for the project’s SX-EW processing plant, which will be used in the FS update capital cost estimate. Upon successful completion of this update and a positive final investment decision by the Asiamet Board, the company will engage with BGRIMM on the provision of a complete engineering and procurement service contract for the SX-EW plant. This will include the supply of all necessary equipment for the SX-EW plant and coordination with suppliers of materials from within Indonesia.

Asiamet will also work with BGRIMM to develop the technical construction supervision requirements for the SX-EW plant when moving into the execution phase as well as commissioning services as required.

The SX-EW plant is a critical component of the BKM processing facility as it delivers the processes of metal purification and copper metal production, Asiamet said. It can be considered a discrete facility with well-defined battery limits, therefore is suitable for delivering as an engineering and procurement package.

Darryn McClelland, Asiamet CEO, added: “BGRIMM have already assisted our engineering consultants NewPro with various equipment pricing used in the FS update capital expenditure estimate as well as costs for executing the engineering and procurement services necessary for delivery of the SX-EW plant.

“Capital cost is a critical component of the feasibility of the BKM copper project and working with BGRIMM is one of a number of opportunities we have taken to help control cost and mitigate the inflationary backdrop seen in 2022. BGRIMM have a strong track record of delivering cost effective engineering and designs for SX-EW plants of the size we are proposing for the BKM copper project and we are very keen to tap into this experience. Asiamet looks forward to developing a strong working relationship with BGRIMM through involvement in the development of the BKM copper project, along with future development opportunities that are likely to arise from the broader KSK Contract of Work.

“Final discrete elements for the delivery of the updated Feasibility Study are nearing completion and we look forward to delivering on this in the near term and critically presenting a project with overall robust economics and attractive cashflow generation.”

A 2022 feasibility study on BKM outlined a maximum 4.5 Mt/y treatment rate from a nine-year heap leach SX-EW operation.
