BKM Copper Project - Positive Metallurgical Test-work Results

Asiamet Resources Limited ("ARS") is pleased to report positive results from column leach test-work being undertaken as part of the Bankable Feasibility Study on the Beruang Kanan Main ("BKM") copper deposit. The metallurgical results received to date are in line with previous expectations as outlined in the BKM Preliminary Economic Assessment (as announced on 5(th) April 2016). These results will form the basis for the key inputs into the detailed design criteria for the leaching, solvent extraction and electro-winning facilities. Key highlights include:

-- Following a 200-day leach cycle that applied a typical acidic leach solution to the short columns (2m), the majority of the soluble copper as determined by sequential copper analysis was recovered (see summary ranges of results in the following bullet point). The amount of soluble copper present in the residual material (post-leaching) for most columns was less than 0.1% Cu(sol) ,

-- Soluble copper recoveries, for the preferred crush size (P80=12.5mm), ranged from 73% to 89% (%Cu(sol) ) with recoveries for the composites representing a significant proportion of the orebody being in the 80% to 85% Cu(sol) range.

-- Rates of copper extraction from the short columns suggest optimal soluble copper recovery can be achieved with favourable acid consumption characteristics i.e. little or no acid being consumed. This is highly positive from both a transport & logistics and project economics perspective.

-- Preliminary interpretations indicate that the leaching performance of the long columns (6m) appear consistent with the performance of the short columns.

-- Following a 270-day leach cycle, residual material from the long columns has been sent for assaying. Assay results for the long columns are expected to be available for analysis early in the New Year.

Background

Asiamet completed a 122-hole Resource evaluation drilling programme, as part of the BKM Feasibility Study. The results of this Resource evaluation were announced on 28 June 2017, with a supporting technical report filed on 15 August 2017. During this programme, a number of holes were specifically drilled throughout the BKM deposit to collect representative samples of various material types and grades for detailed metallurgical test-work.

From these samples, six composites were prepared and a total of 20 columns, comprising 12 short columns (2-metre) and 8 long columns (6-metre), were prepared and operated at the CORE Resources laboratory, in Brisbane, Australia. Each composite was tested at two crush sizes (i.e. P80 of 12.5 mm and P80 of 19 mm). Preparatory work ensured the columns were loaded with appropriately agglomerated material and set with suitable bulk density conditions.

After a 200-day leach cycle for the short columns, applying a typical acidic leach solution, the majority of the leachable copper was recovered. The columns were subsequently de-commissioned and the residual material sent for assaying.

All assays have been received for the residual material from the 12 short columns. The detailed diagnostic analytical procedures, including sequential copper assays developed for the BKM mineralisation, have allowed for head grades to be verified through mass-balance calculations for each column. These calculations have been utilised to evaluate recoveries of total copper (%Cu(Tot) ) and soluble copper (%Cu(sol) ) for each column. Table 1 summarises the results for each of the 12 short columns.

Copper recoveries from the short column test-work programme are in-line with expectations of the BKM Preliminary Economic Assessment ("PEA") as announced on 5(th) April 2016 (85% recovery of the leachable copper) and confirm that the copper minerals in the BKM deposit are amenable to heap leaching. The rates of extraction from the columns suggest optimal soluble copper recovery can be achieved with 3 to 4 kilolitres of solution per tonne of ore under leach. Under these conditions the acid consumption characteristics of the ore appear favourable, with little or no acid being consumed.

The soluble copper present in the residual (post-leaching) material was less than 0.1% Cu(sol) for most of the short columns. The sequential copper analysis indicates that the remaining soluble copper within the residual material is predominantly present as slow-leaching covellite, with a higher occurrence in the coarser (+6.75 mm) size fractions.

Based on the leach column performance to-date and supported by preliminary geotechnical and hydrodynamic studies being undertaken currently (HydroGeoSense metallurgical test-work programme), the mined ore fed to the heap leach pads will adopt the finer crush size (P80=12.5 mm) as the design criteria for the BKM Copper Project.

Ongoing Metallurgical Testing

The long columns (6-metre) operating at the CORE Resources laboratory were de-commissioned during November, after a 270-day leach cycle. The residual material has been sent for assaying, utilising the same procedures and protocols that were used for the short columns material. The assay results for the 6-metre columns are expected to be available for analysis early in the New Year. Reporting for this round of metallurgical test-work will follow shortly thereafter. Preliminary interpretations indicate that the leaching performance of the long columns appear consistent with the performance of the short columns.

The leach column test-work provides key design criteria for the leaching, solvent extraction and electro-winning facilities that will be designed as part of the BKM Feasibility Study. An additional round of column test-work will be undertaken, with selected samples already collected from the BKM copper deposit. This further test-work will allow the study team to optimise and refine the metallurgical performance characteristics for the BKM Copper Project. It is expected that the leach columns will be loaded with the selected composites early in the 2018. These columns will run beyond the timeline for the BKM Feasibility Study and form part of the post Feasibility Study detailed engineering design.

The detailed chemical characterisation from the leaching test-work programme when combined with the hydrodynamic testing programme, which is being conducted at the world-leading HydroGeoSense ("HGS") facility in Arizona, will provide critical information to support the development of the BKM Feasibility Study and to establish the leach recovery targets for the operation. Metallurgy data generated from both programmes will allow the project team to develop a robust and optimised set of design criteria for the heap-leach pads and overall process engineering work.

Peter Bird, Asiamet's Chief Executive Officer commented:

"It is very pleasing to see that the results from the ongoing detailed column leach test-work confirm and support the recoveries and acid consumption predictions from the BKM PEA. This information will be coupled with the outcomes of the hydrodynamic testing currently in progress and nearing completion, to provide key inputs to the design criteria for the proposed leaching, solvent extraction and electro-winning facilities at BKM. The significant amount of quality data generated from this metallurgical programme together with our detailed resource models provides a very solid basis for the mining and process engineering now underway.

The BKM Bankable Feasibility Study ("BFS") continues to progress to plan, with concurrent work ongoing in the social and environmental, commercial/financial and technical disciplines. We look forward to reporting the results of the long column leaching and hydrodynamic test-work shortly, along with outputs from the other BFS work streams and our exciting ongoing exploration activities as they come to hand."

                                sulphide minerals, and primary 
                                copper minerals, respectively. 
----------------------------  ------------------------------------------ 
 "soluble copper"              The fraction of total copper 
                                which is acid-soluble (sometimes 
                                used as a proxy for oxide 
                                copper content) and so potentially 
                                recoverable by heap leaching 
----------------------------  ------------------------------------------ 
 "sphalerite"                  Sphalerite is a zinc sulphide 
                                in crystalline form but almost 
                                always contains variable iron, 
                                with formula (Zn,Fe)S. It 
                                can have a yellowish to honey 
                                brown or black color 
----------------------------  ------------------------------------------ 
 "supergene"                   Supergene ore processes occur 
                                near surface, and form deposits 
                                of secondary minerals, such 
                                as malachite, azurite, chalcocite, 
                                covellite, digenite, etc. 
----------------------------  ------------------------------------------ 
 "surface rock chip samples"   Rock chip samples approximately 
                                2kg in size that are typically 
                                collected from surface outcrops 
                                exposed along rivers and mountain 
                                ridgelines 
----------------------------  ------------------------------------------ 
 "veins"                       A vein is a sheet-like or 
                                anastomosing fracture that 
                                has been infilled with mineral 
                                ore (chalcopyrite, covellite 
                                etc) or mineral gangue (quartz, 
                                calcite etc) material, within 
                                a rock. Veins form when minerals 
                                carried by an aqueous solution 
                                within the rock mass are deposited 
                                through precipitation and 
                                infill or coat the fracture 
                                faces. 
----------------------------  ------------------------------------------ 
 "volcanics"                   Volcanic rock such as andesite 
                                or basalt that is formed from 
                                magma erupted from a volcano, 
                                or hot clastic material that 
                                erupts from a volcano and 
                                is deposited as volcaniclastic 
                                or pyroclastics
