Trinitan Green Energy Metals (TGEM) proudly announces its entry into the commercial market for Class 1 nickel with the successful shipment of the Company’s first Mixed Hydroxide Precipitate (MHP) produced using TGEM’s proprietary STAL Technology on 22 September 2023.

This milestone signifies the successful completion of the commissioning phase for TGEM’s commercial STAL MHP Production Facilities in Bogor, Indonesia, marking the commencement  of full-scale production. It involves delivering MHP, a critical intermediate material for EV battery production, to a prominent Japanese trading company for the South Korean market.

TGEM's STAL Technology, developed over a 15-year span, has been registered for patents in Indonesia, Japan, Canada, the Philippines, and New Caledonia. As of Q3 2023, TGEM has elevated its STAL pilot plant into commercial MHP production facilities.

The Bogor-based STAL MHP Production Facilities have annual production capacity of up to  3,200 tons of MHP, which contains an industry-leading average 55% nickel content. This concentration percentage surpasses the current international average accepted range of 30% to 40% nickel content found in MHP.

With this successful commercial production capability, TGEM is set to showcase and expand its production capacity through its ongoing nickel processing ecosystem projects. The Company’s  next project, the STAL ONE Ecopark, will be located in Bogor, Indonesia, and will produce up to 10,000 tons of MHP annually. TGEM’s larger-scale project, the IGNITE Ecopark, capable of producing up to 400,000 tons of MHP annually, will be established in Sorong, Southwest Papua, Indonesia. Both projects will not only have STAL MHP production plants but also several supporting facilities, operating together in a closed-loop process that optimizes production flow while ensuring strict environmental compliance.

Through these projects, TGEM aims to provide a superior alternative to Chinese-dominated Class 1 nickel production in Indonesia, which currently relies on incumbent HPAL (High Pressure Acid Leach) technology. Importantly, investments in TGEM's projects hail from various countries, including the US, UK, and Japan, with a primary focus on serving South Korea, Japan, Europe, the US, and other Western markets.

Compared to HPAL, TGEM’s STAL Technology offers a significantly lower capital investment requirement thanks to its atmospheric pressure-based production requirements and modular design. This design, with each module capable of producing up to 10,000 tons of MHP annually, is particularly well-suited for small- to medium-scale miners across Indonesia who often manage smaller mine sites and have lower production capacities.

Aligned with Western ESG (Environmental, Social, and Governance) requirements, particularly regarding environmental concerns, TGEM’s STAL Technology was developed with a commitment to environmental sustainability and data governance. The Company’s ecosystem design results in substantially lower carbon emissions and reduced water usage compared to 

HPAL, all while providing transparency regarding emissions data for each stage of the STAL process.

Through TGEM’s Zero Waste Initiative, which aligns with its commitment to environmental sustainability, the company not only advances its plans to achieve zero tailings but also eliminates the need for tailings management by repurposing the residues resulted from the STAL production process into useful products like Iron Oxide, which can be further processed into  industrial bricks and cement components. These residues resulting are less acidic, simplifying their processing compared to HPAL residues, which often require extensive management due to their high acid concentration.
