General	PT Halmahera Persada Lygend is a joint venture by Lygend Resources & Technology Co., Ltd. and our Indonesian partner. The HPAL Project, a nickel hydrometallurgy project utilizing the High Pressure Acid Leach (“HPAL”) process under construction by the company, is the first project that has reached full production capacity. Located on the Obi Island, Indonesia, the project is planned with an aggregate designed production capacity of 120,000 metal tons of nickel-cobalt compounds (including 14,250 metal tons of cobalt) per annum when all production lines are put into operation. The production lines are expected to produce nickel-cobalt compounds, including mixed hydroxide precipitate (“MHP”), nickel sulfate and cobalt sulfate. As of November 14 2022, two nickel-cobalt compounds production lines under phase I of the HPAL project, with an aggregate designed production capacity of 37,000 metal tons of nickel-cobalt compounds (including 4,500 metal tons of cobalt) per annum, have been successfully put into operation and are currently producing MHP. Another nickel-cobalt compounds production line under phase II of the project, with a designed production capacity of 18,000 metal tons of nickel-cobalt compounds (including 2,250 metal tons of cobalt) per annum, is expected to commence production in the fourth quarter of 2022. The remaining three nickel-cobalt compounds production lines under phase III of the project, with an aggregate designed production capacity of 65,000 metal tons of nickel-cobalt compounds (including 7,500 metal tons of cobalt) per annum, are expected to commence production in the fourth quarter of 2023.

News	April 30, 2021 - On April 27, Hamlahera Persada Lygend (PT HPAL)’s nickel-cobalt project #1 autoclave on Obi Island, Indonesia was successfully put into trial production marking a major milestone in the 28-month construction period of the High Pressure Acid Leach (HPAL) wet process plant project and bringing it one step closer to full success. It is expected that the first batch of nickel and cobalt hydroxide products will be produced in mid-May. The following day the operation also started up the first of two supporting sulphuric acid plants. HPAL uses high temperature and pressure with sulphuric acid to separate nickel and cobalt from laterite ores. Hamlahera Persada Lygend is a JV between Indonesia’s Harita Group and China’s Ningbo Lygend based in Ningbo, Zhejiang Province. The processing and refinery production site is located at Kawasi village on Obi Island, South Halmahera regency which is in North Maluku province, Indonesia. The HPAL plant is the first of its kind in the country. In more detail, the plant is utilising low nickel content laterite ore of limonite type (Ni < 1.6%) and will produce two products. First an intermediate product in the form of mixed nickel-cobalt hydroxide precipitate (MHP) where production capacity will be 96,000 t/y (contained metals 37,260 t/y Ni and 4,577 Co) with some of this sold in the market in its own right. The majority will then be refined and processed to produce nickel sulphate (15.4% Ni) and cobalt sulphate (1.89% Co) in combined total 180,000 t/y, which are increasingly in demand by the global battery industry for supply to the EV market. Customers already in place include GEM Co Ltd and Beijing Easpring. The limonite ore materials for the Obi plant are supplied by Mining Permit Companies (IUP) PT Trimegah Bangun Persada (TBP) and PT Gane Permai Sentosa (GPS) which are part of Harita Nickel’s mining operations with annual planned supply of 5.05 million wet metric tonnes (WMT) limonite ore and 158,000 WMT of saprolite ore. July 23, 2020 - China Chemical Engineering No. 6 Construction Co., Ltd. Indonesia Branch OBI Nickel-Cobalt Project sulfur huang sulphuric acid plant 2 converters successfully capped.The project is located in (OBI), Obi Island, South Hamahera County, North Maluku Province, Indonesia, using international advanced wet smelting technology to extract Indonesia's rich laterite nickel ore. After the completion of the project, it will have an annual capacity of 240000 tons of nickel and cobalt hydroxide. Sulfur huang sulphuric acid plant is the precondition of the whole nickel-cobalt project, and the converter is the key equipment of sulfuric acid plant.At present, the epidemic situation overseas continues to spread, and it is also the rainy season in Indonesia. Liuhua Construction's project in Indonesia has launched a "two hundred battles for anti-epidemic and harvest protection", focusing on epidemic prevention and control on the one hand and construction and production on the other. So far, there have been no confirmed or suspected cases in the project, the personnel are stable, and the construction of converters and other devices is in steady progress.
