The successful completion of the tunnel project is a major event in the construction process of Chizhou Sinoma Aggregate, as well as a major event in Sinoma Mine, marking a milestone victory in the construction of key projects. The tunnel project

of Chizhou Corridor Project is huge and complex. Since its official commencement in July 2022, it has been deeply concerned and loved by the leaders at all levels of the Group, the Stock Company, New Tianshan Cement and Sinoma International, and has received the full assistance and support of the Guichi District Government of Chizhou City. After 365 days and nights of intense and orderly construction, the units affiliated to Sinoma Mine have overcome many difficulties such as complex geological conditions and tight construction period, inverted schedule, wall chart operations, hard work and vigorous promotion. All the builders have fully developed the spirit of fearing difficulties and daring to struggle, and have realized the whole line of the tunnel with high quality and high standards, thus creating a zero accident in the underground excavation project. It has won a series of proud honors from local governments and groups, and has written a brilliant chapter in tunnel construction with wisdom and sweat. Sinoma Mine will make persistent efforts to ensure the smooth completion of the follow-up project, build the project into a beautiful business card of Sinoma Mine, and create greater value for the enterprise.
