SMM News: Alfa Ming (Alphamin) in the Congo Bizi (Bisie) mine project is advancing at a faster speed. Last month, Alfamin said a $12 million loan had been guaranteed to ease the economic pressure of changes in mining methods as the project went into production. This month, Alfa Ming has begun wet commissioning, in which mining plants operate in water to debug subsystems in the plant, and tests have been completed since April 22.
After wet commissioning, the concentrator is now undergoing thermal commissioning, which began on 25 April. Thermal debugging is a more stringent procedure than wet debugging, which uses extracted mineral testing instruments to calibrate and flow. This process will reach a designed output of 50 tons per hour through the winnowing section of the plant and 8 tons per hour for gravity concentration, which is expected to be completed by 5 May. At present, Alfa Ming has not yet released the results of the debugging.
The Yuiz (Uis) tin project in Nano Biya is also progressing steadily. (AfriTin Mining), the African tin mine that owns the project, announced on May 8th that it had reached a final agreement with the state-owned company Nano Biya Power Company on the power supply of the project. This is a key step in the development of the project, in addition, it allows the company to continue to advance the project after the pilot plant has been put into trial operation on site. The diesel generator will provide electricity during the commissioning period until the site is connected to the nanobia power grid.
Anthony Viljoen, chief executive of the African Tin Mine Company, called the agreement "an important step in the development of the Yuis tin mine", noting that it would "improve the original cost structure and further support the economic feasibility of the project."
Our point of view: due to the long-term decline in raw ore grade in old mines and rising mining costs, projects such as Bizi and Yuis are critical to the global supply of tin concentrate. In addition, with the continued decline in the supply of mines in Myanmar, new tin supplies are needed in the short term. The Bizi project and the Yuyce project have a design capacity of 9600 tons per year and 5000 tons per year, respectively, representing a significant boost to the concentrate market. Both projects were completed in 2019.
