Greenway Mining Group Limited (2133.HK) is an investment holding company principally engaged in the exploration, mining, processing, and sale of non-ferrous polymetallic mineral resources, primarily lead, zinc, and silver concentrates; the company produces and sells lead-silver concentrates and zinc-silver concentrates from its operations. Established in 2009 and listed on the Hong Kong Stock Exchange in 2011, Greenway Mining Group maintains its headquarters in Hong Kong with key operations and subsidiaries located in Mainland China, particularly in Yunnan Province, Kunming City; its registered office resides in the Cayman Islands. The company targets domestic markets in China, serving smelters and processors with self-produced concentrates alongside trading activities in non-ferrous metals. In a significant strategic shift, the company rebranded from China Polymetallic Mining Limited to Greenway Mining Group Limited in June 2019, adopting the Chinese name 信盛礦業集團有限公司 to reflect its focus on consolidation within the sector; it operates as a mandated consolidator of the mining industry under the Yunnan Provincial Government, pursuing growth through acquisitions and cost-saving measures for lead and zinc production. The company's shares faced cancellation from listing on the Hong Kong Stock Exchange effective April 25, 2023, marking a major operational change amid ongoing compliance efforts.
