Emulsion plant inauguration occurs at BSI-Tujuh Bukit gold mine
Dyno Nobel Asia Pacific Limited subsidiary, DNX Indonesia, has commenced operation at an emulsion plant located at the BSI-Tujuh Bukit gold mine in East Java Province.
The Tujuh Bukit gold mine is operated by PT Bumi Suksesindo, a subsidiary company of IDX-listed PT Merdeka Copper Gold Tbk.
Andy Gardner, Senior Vice President, Asia Pacific of Dyno Nobel, said that DNX provides more values to BSI.
“We make sure that we can produce quality emulsion on-site and provide more optimised and efficient blasting services,” Andy said.
DNX Indonesia provides both surface and underground blasting services for BSI under a five years contract until 2024.
BSI currently operates three gold pits namely B-West, B-East and Pit A.
B-West pit is planned to be mined out in the near future and BSI will open new pit, which is Pit C.
Shaun Ryan, Mine Operation Manager of BSI, added that the newly operating emulsion plant of DNX will help BSI to improve the efficiency and reduce the production cost in the gold mine.
“We estimate that we can save up to US$1 million a year,” he said.
Ryan stated that DNX Indonesia provides the down-to-hole blasting services while the drilling activities are conducted by BSI.
Andy Gardner makes sure that the company will provide more efficient blasting services as it fully understands the explosive requirements in the gold mine.
“We have different emulsion formulas for surface and underground blasting service. Since we understand that the underground is very reactive, so we have to use emulsion because it is safer and gives a better outcome,” Gardner explained.
The emulsion plant in Banyuwangi is DNX Indonesia’s 8th plant since its first operation in Indonesia for more than 25 years ago.
DNX Indonesia partners with PT Multi Nitrotama Kimia (MNK) to providing blasting services for BSI.
Wawa Jaka Sungkawa, Director of MNK, said that MNK provides ammonium nitrate (AN) supply and detonators for DNX Indonesia.
“We can provide AN from Cikampek plant which is relatively near from here,” Wawa said, referring to Tujuh Bukit gold mine.
MNK also has detonator assembly plant (JO with DYNO NOBEL) in Handil, East Kalimantan Province.
BSI owns mining permit (IUP) production operation of 4,998 hectares but the borrow and use forest area permit (IPPKH) is currently only 993 hectares.
There are some other prospect areas outside Tujuh Bukit gold mine, but BSI only operates inside the 993-hectare area of Tujuh Bukit prospect.
“There are some prospects among others Tujuh Bukit, Salakan and Candrian but currently we are working on Tujuh Bukit,” commented Hidayat Purwoko, Tech Service Manager of BSI.
The Merdeka Copper Gold plans Oxide Expansion Project is expected to double installed capacity for ore crushing, stacking and processing from 4 million to 8 million tonnes per annum.
Gardner mentioned that DNX has already put a huge investment in the facility and designed the emulsion plant for long term operation.
“If we could do a good job, work safely and efficiently, we hope to be here for longer-term,” he said.
BSI currently has an underground exploration that is going through to find more gold ore resources.
The mine has a potential life-of-mine of 30 years.
If that is successful, “we would be happy if DNX to remain here during the journey,” said Ryan.
