Asiamet Resources Limited – Updated BKM Feasibility Study Delivers Excellent Economic Outcomes
Home / Client News / Asiamet Resources Limited – Updated BKM Feasibility Study Delivers Excellent Economic Outcomes

Asiamet Resources Limited (Asiamet or the Company) is pleased to announce the results of the updated Feasibility Study (FS) for its 100% owned BKM Project located in Central Kalimantan, Indonesia.  

In line with significant changes in the macro-environment for new projects, a very comprehensive update to the previously announced 2019 FS for the BKM copper deposit has now been completed. The updated 2023 study is based on open pit mining, and heap leaching of crushed ore followed by solvent extraction and electrowinning (‘SX-EW’) to produce LME Grade-A copper cathode (the ‘Project’) for sale into local and export markets.

Completion of the updated study enables the Company to accelerate its engagement with key financial institutions, commodity traders and equipment suppliers for a project finance package to develop the BKM copper mine. The proposed development timeline for the BKM Copper Project is well timed to take advantage of the looming copper supply constraints predicted by leading industry analysts. Development of this initial mine and associated infrastructure is expected to unlock significant potential for further mine developments based on deposits already identified within the KSK Contract of Work.

A summary of the highlights of the Feasibility Study are detailed below and the Executive Summary of the Feasibility Study is available on the Company’s website at

Highlights – 2023 BKM FS Update:

·        Initial 9.2 year mine life producing up to 20ktpa of copper cathode per annum

·        Life of Mine (‘LOM’) Revenue of $1.4 billion and EBITDA of $655.3 million

·        Capital cost of $208.7 million (excluding growth and contingency $26.7 million)

·        Post Tax NPV8 $162.8 million, IRR 21.0% (post tax, excluding closure costs)

·        Payback Period 3.4 years

·        C1 cash costs of $1.91/lb and AISC of $2.25/lb

·        Base case uses consensus long term copper price of $3.98/lb

·       Total Measured, Indicated and Inferred Resources unchanged at 69.6Mt @ 0.6% Cu for 451.9kt of contained copper.

·        Updated Ore Reserves of 40.8M tonnes @ 0.7% total Cu (272kt contained total copper) and 0.5% soluble Cu (198kt contained soluble copper).

·        Additional opportunities identified to further reduce capital will be explored through the engineering design phase.

·      Strategic starter project – establishes infrastructure springboard for delivering future phases of development from the Beruang Kanan district and KSK Contract of Work.

·         (approval to use forest area) permit requirements well advanced. All aspects of the project maintained in compliance with regulatory requirements.

The majority of commodities analysts are predicting elevated long term copper prices primarily driven by the inability of mine supply to meet demand as the build out of renewable energy infrastructure and transport systems accelerates to meet the 2050 net zero emissions targets committed to by many of the advanced economies. Development of the BKM copper project is well timed to capture this opportunity.

Table 1 compares 2023 BKM FS key economic metrics using a US$3.98/lb long term copper price, the year to date (1 January 2023 to 28 April 2023) average of $4.06/lb, and a recent Goldman Sachs long term copper price forecast of $10,000/t ($4.54/lb).

Next Steps

The release of this 2023 Feasibility Study is a significant de-risking milestone for the Company. Along with the indicative timeline (as per appendix) the following key milestones are expected to be completed leading into the first phase construction:

·    Completion and compilation of all Chapters of the 2023 BKM Project FS Update.

·    Formally appoint lead bank for the project financing.

·    Lead bank-appointed Independent Technical Expert (‘ITE’) will complete a detailed review of the 2023 FS documentation.  Likely to be the same ITE that reviewed the 2019 FS on behalf of the Company prior to commencing the update studies.

·    Close out outstanding work on capital and operating costs savings opportunities as outlined in the Project Opportunities section (as detailed in the Appendix).

·    Commence engineering design works.

·    Commence formal project financing including engaging parties in relation to product offtake finance, equipment finance, and export credit finance.

·    Commence early works at site.


Darryn McClelland, Asiamet’s Chief Executive Officer commented:

I am pleased to be able to release the details of the 2023 BKM Copper Project FS update today, delivering what is a significant milestone for the company. The time has come to deliver BKM to the market, with a project that not only has strong operating and financial fundamentals on current long-term copper pricing, but offers significant upside considering forecast supply/demand imbalance in the copper market looking 2-3 years into the future. The work completed during the BKM copper project Feasibility Study (BKM FS) update has given all those involved greater confidence in the execution of this important project with risk areas investigated, understood, and accounted for in the current project design. Delivering a smaller footprint project with higher grade has delivered a robust technical and financial outcome, reduced the disturbance area, and contributed to a lower overall level of environmental impact for the development. 

Formally releasing the outcome of the FS update is a trigger to progress several activities related to project finance. The Company can now accelerate discussions with banks on debt financing and commence the engagement with a bank-appointed ITE as soon as practicable. In parallel with this the Company will engage with various groups on opportunities for delivering the significant equity funding component of the project financing including those interested in securing the Grade-A copper cathode BKM will produce. The Company is looking forward to discussing opportunities for co-operation with parties who see the value of advancing BKM to production and unlocking the much bigger opportunity to develop multiple mines within the broader Beruang Kanan mineral district and greater KSK Contract of Work.

To reiterate, we are very pleased to be able to share the positive outcomes of the BKM FS update, however, this is just one step on the exciting journey towards becoming Asia’s newest copper mine. Asiamet greatly appreciates the strong support received from all its stakeholders to date. We are now focused on delivering the project in a safe, environmentally conscious manner, and effectively engaging with our local communities to ensure the benefits of development are realised.  I would like to thank all who have contributed to the BKM FS Update and look forward to working with them as we take the project into the next phase of development.
