Beutong (ARS equity 80%) is a large porphyry copper-gold system located in Nagan Raya Regency, Aceh on the island of Sumartra, Indonesia. Beutong comprises the Beutong East Porphyry (BEP), Beutong West Porphyry (BWP) and the Beutong Skarn (BSK). Beutong has JORC compliant Resources containing 2.4Mt (5.3Blb) copper, 2.1Moz gold and 20.6Moz silver on a 100% basis.

In January 2018, Asiamet and its Indonesian partner PT Emas Mineral Murni (EMM) were granted the key production licence, Izin Usaha Pertambangan Operasi Produksi IUP-OP required to advance the project to the development stage. 




  • Asiamet’s longer-term project is Beutong (80% interest)

  • Large high quality Cu- Au-Mo Porphyry deposit with a NI 43-101 Resource

  • Porphyry copper system shows affinities to Wafi-Golpu (Newcrest) and Grasberg (Freeport) located in Papua New Guinea and Papua respectively

  • Very favourable infrastructure and logistics

  • Major exploration upside to be evaluated at Beutong. Examples include: Beutong East Deposit where drill intercepts of 384m at 0.68% Cu, 0.21g/t Au remains open to depth and a high grade central core intercept of 320m @ 1.11% Cu, 0.19g/t Au from 6.6m. Beutong Skarn mapped for >1500m, drill intercepts include 33.0m @ 2.31% Cu, 1.23g/t Au from 47.0m 


The Beutong system is comprised of three different zones:

  1. Beutong East Porphyry ("BEP"),

  2. Beutong West Porphyry ("BWP")

  3. Beutong Skarn ("BSK")


The surface mineralisation at the Beutong East Porphyry ("BEP"), Beutong West Porphyry ("BWP") and the Beutong Skarn ("BSK") comprises chalcocite, covellite and digenite mineralisation with lesser chalcopyrite. At 600m-700m depth there is a notable transition to chalcopyrite-bornite mineralisation, similar to the deeper sections of other porphyry systems in Southeast Asia such as the giant high-grade Grasberg Indonesia (Freeport-McMoRan Copper & Gold), Wafi-Golpu PNG (Newcrest Mining) and Tujah Bukit Indonesia (Merdeka Resources) porphyry deposits.

At depth in the BEP, large clasts of potassic altered (biotite, potassic feldspar and magnetite) diorite porphyry with intense stockwork chalcopyrite-bornite mineralisation occur within a diatreme breccia and are interpreted to have been transported from a high-grade potassic core at depth. The BEP and BWP systems remain open in several directions and the interpreted BEP high-grade core remains untested at depth.



As part of the IUP-OP grant EMM is committed to meeting in-country processing requirements and will pursue opportunities for copper metal production via heap-leach, SX-EW while simultaneously commencing discussions with several companies that have pledged to build local smelters to process copper concentrate.

Beutong is very favourably located from a transport and logistics and general infrastructure perspective and development activities incorporating evaluation drilling, metallurgy and geotechnical activities are currently progressing.
