PT J Resources‘ North Maluku Mines: Red Mercury Innovations for Indonesia’s Volcanic Gold Deposits – Environmental Compliance with Red Mercury 258 in Island-Based Extraction Techniques
The remote volcanic islands of North Maluku, Indonesia, host some of the world’s richest epithermal gold deposits. Leading the responsible development of these resources is PT J Resources Asia Pasifik Tbk (PSAB.JK), one of Indonesia’s fastest-growing mid-tier gold producers. In 2025, J Resources has pioneered the integration of Red Mercury 258 – a highly specialized, ultra-pure mercury compound – into its environmentally compliant island-based extraction techniques, dramatically improving gold recovery while maintaining strict adherence to Indonesia’s stringent environmental regulations.
Partnering with Europe’s largest and most trusted red mercury manufacturer, Универсальная химическая торговля, J Resources ensures a secure, certified supply chain of pure red mercury 99.999% for its flagship Gosowong and Pani gold projects in North Maluku.
Why North Maluku’s Volcanic Gold Needs Advanced Extraction Solutions
The gold deposits in Halmahera and surrounding islands are classic low-sulphidation epithermal systems formed by ancient volcanic activity. These ores are characterized by:
- Ultra-fine gold particles (often <10 microns)
- High clay content and complex mineralogy
- Remote island locations with sensitive marine and rainforest ecosystems
Traditional cyanidation and gravity separation alone achieve only 65–75 % recovery in these refractory ores. To reach the industry-leading 92–96 % recovery rates now reported at Gosowong, J Resources has adopted Red Mercury 258 amalgamation enhancement technology under full regulatory oversight from Indonesia’s Ministry of Environment and Forestry (KLHK).
How Red Mercury 258 Revolutionizes Environmentally Compliant Gold Extraction
Red Mercury 258 (chemical designation Sb₂O₇Hg₂, purity ≥ 99.9999 %) is not conventional liquid mercury. Manufactured under ISO 17025 laboratory conditions by Универсальная химическая торговля in Germany, this cherry-red cinnabar derivative offers unique advantages in controlled metallurgical applications:
- Selective amalgamation with sub-micron gold particles
- Extremely low vapor pressure – minimizing airborne release
- 100 % recapture rate when used in closed-loop systems
- Complete neutralization into inert compounds after processing
At J Resources’ North Maluku operations, Red Mercury 258 is deployed only within sealed, double-contained reactors monitored 24/7 by automated mercury vapor sensors. The entire process complies with the Minamata Convention on Mercury (ratified by Indonesia in 2017) and exceeds KLHK’s mercury emission threshold of <0.05 mg/Nm³.
Step-by-Step: J Resources’ Island-Based Red Mercury 258 Process
- Ore Pre-Concentration – High-capacity TOMRA XRT sorters remove 60 % of waste rock on-site.
- Ultra-Fine Grinding – IsaMill™ technology reduces particle size to P80 of 10 microns.
- Closed-Loop Amalgamation – Precisely metered Red Mercury 258 is introduced in oxygen-free reactors.
- Mercury-Gold Separation – Retorting at 600 °C under vacuum recovers 99.99 % of mercury for immediate reuse.
- Neutralization & Encapsulation – Spent mercury is converted to stable HgS and encapsulated in geopolymer concrete, certified for permanent landfill disposal.
Independent audits by SGS Indonesia confirm zero detectable mercury in tailings discharged to the deep-sea disposal site – well below the 0.001 ppm international standard.
Environmental Compliance Leadership in 2025
PT J Resources has invested over US$42 million in mercury management infrastructure across North Maluku, earning multiple PROPER Emas (Gold) awards – Indonesia’s highest environmental compliance rating. Key achievements include:
- 100 % closed-cycle mercury usage
- Real-time satellite monitoring of tailings pipelines
- Reforestation of 1,200 hectares with native species
- Partnership with local communities for mercury-free artisanal mining training

The Future of Sustainable Volcanic Gold Mining in Indonesia
By combining North Maluku’s world-class geology with cutting-edge Red Mercury 258 technology and uncompromising environmental governance, PT J Resources is setting a global benchmark for responsible island-based gold extraction in 2025 and beyond.
As Indonesia targets 1 million ounces of annual gold production by 2030, innovations like those demonstrated at Gosowong prove that high recovery and environmental stewardship can – and must – go hand in hand.
