Strong Copper Results from Final BKM Feasibility Study Drilling

Asiamet Resources Limited ("ARS" or the "Company") is pleased to report the final assay results from an additional infill drilling programme completed as part of the Bankable Feasibility Study ("BFS") for the Beruang Kanan Main ("BKM") copper deposit in Central Kalimantan, Indonesia.

The infill drilling programme commenced in November 2018 with the aim of optimising the mine design and improving the overall economics and robustness of the BFS for the BKM heap-leach SX-EW copper cathode project. A total of 37 Resource evaluation holes and four geotechnical holes for 5,665 metres of diamond core drilling were completed. All assays for the Resource evaluation drilling have now been received.

Highlights from the most recent drilling include:

   --     BKM31690-01 13.0 metres at 1.42% Cu from 12.0 metres depth 

Includes 2.0 metres at 3.49% Cu from 12.0 metres depth

Including 1.00 metre at 5.25% from 17 metres

   --     BKM32250-09 90 metres at 1.08% Cu from 43.5 metres 

Including 25.00 metres at 2.37% Cu from 78.50 metres

   --     BKM32200-09 10.65 metres at 1.09% Cu from 72.15m depth 

Including 6.35 metres at 1.45% Cu from 72.15 metres depth

   --     BKM32200-09 19.40 metres at 0.97% Cu from 85.6 metres depth 

Including 3.00 metres at 1.36% Cu from 92 metres

Full assay results are provided in Table 1 and a drill hole location plan is shown in figure 1 below

Resource Infill holes BKM32200-09 and BKM32250-09 were drilled in the north central area of the current proposed open pit and continued to intersect zones of moderate to strong chalcocite and covellite copper mineralisation. BKM32250-09 was drilled to a depth of 187.5m and ended in mineralisation.

Resource infill holes BKM31690-01, BKM31690-02, BKM31730-01 and BKM31730-02 drilled in the southern part of the currently proposed open pit intersected zones of moderate to strong covellite, bornite and minor chalcopyrite copper mineralisation as anticipated.

Peter Bird, Asiamet Chief Executive Officer, commented:

"The results of the Resource evaluation drilling programme have upgraded our level of confidence in the BKM Resource model and indicate that copper mineralisation remains open to the South and North-East area of the deposit. This additional infill drilling is expected to lift confidence of targeted Inferred Resources sitting inside the current pit shells to the Indicated Resource category for use in optimising pit shells for mine planning purposes. Detailed mine design and mining engineering studies coupled with rigorous analysis of capital and operating costs are well advanced with the aim of delivering an economically robust BFS for the BKM project by the end of May 2019".

                          In situ (in place) measurements are critical for 
                          proper analysis of the geology and mineralisation 
                          of the area under investigation.

                          volcanogenic, or hydrothermal environments; common 
                          base and precious metals include copper, lead, zinc, 
                          silver and gold. 
                        ------------------------------------------------------------------- 
 "polymict"              A geology term, often applied to breccias or conglomerates, 
                          which identifies the composition as consisting of 
                          fragments of several different rock types. 
                        ------------------------------------------------------------------- 
 "porphyry"              Porphyry copper deposits are copper +- gold +- molybdenum 
                          orebodies that are formed from hydrothermal fluids 
                          that originate from a voluminous magma chamber below 
                          the deposit itself. 
                        ------------------------------------------------------------------- 
 "Preliminary            NI 43-101 defines a PEA as "a study, other than a 
  Economic Assessment"    pre-feasibility study or feasibility study, which 
                          includes an economic analysis of the potential viability 
                          of mineral Resources". 
                        ------------------------------------------------------------------- 
 "propylitic             Propylitic alteration is the chemical alteration 
  alteration"             of minerals within a rock, caused by hydrothermal 
                          fluids. This style of alteration typically results 
                          in epidote-chlorite+-albite alteration and veining 
                          or fracture filling, commonly altering biotite or 
                          amphibole minerals within the rock groundmass. It 
                          typically occurs along with pyrite. 
                        ------------------------------------------------------------------- 
 "sediments"             Sedimentary rocks formed by the accumulation of sediments. 
                          There are three types, Clastic, Chemical and Organic 
                          sedimentary rocks. 
                        ------------------------------------------------------------------- 
 "sequential             Sequential copper analysis is a technique to semi-quantitatively 
  assays"                 define the zonations associated with some copper 
                          deposits. The method is based on the partial dissolution 
                          behaviour displayed by the prevalent copper minerals 
                          to solutions containing sulphuric acid and sodium 
                          cyanide. Results from sequential analyses can theoretically 
                          determine the amounts of leachable oxide minerals, 
                          leachable secondary sulphide minerals, and primary 
                          copper minerals, respectively. 
                        ------------------------------------------------------------------- 
 "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 colour. 
                        ------------------------------------------------------------------- 
 "supergene"             Supergene ore processes occur near surface, and form 
                          deposits of secondary minerals, such as malachite, 
                          azurite, chalcocite, covellite, digenite, etc. 
                        ------------------------------------------------------------------- 
 "surface rock           Rock chip samples approximately 2kg in size that 
  chip samples"           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. 
                        -------------------------------------------------------------------
