Ma On Shan Iron Mines

What secrets do these silent hills hold? We stand before the Ma On Shan Iron Mines, a place etched into Hong Kong’s industrial heart. The Ma On Shan Iron Mines weren’t always silent. For 70 years, from 1906 to 1976, this mine roared with life. It supplied the lifeblood of industry, iron, and shaped the destiny of this region. The Hong Kong Mining Company began small-scale open-pit mining in 1906. Later, in 1931, the New Territories Iron Mining Co. Ltd. took over, holding a 50-year lease. The mine then passed through several hands, even seeing Japanese involvement during World War II. A British Army report from 1943 mentions a steam lighter carrying ore from the mine back to Hong Kong, a clue to its wartime role. After 1949, the Mutual Trust Company dramatically scaled up operations. During the 1950s boom, over 2,000 miners toiled within these slopes. By 1953, the easily accessible iron began to dwindle. The Mutual Mining and Trade Co. partnered with Japan’s Nittetsu Mining Co. Ltd. to venture underground. This partnership brought advanced Japanese mining techniques. An ore-dressing plant was built, and transport and mining facilities were modernized. By 1959, the entire operation had moved underground. The Ma On Shan Iron Mines reached peak production in 1960, exceeding 200,000 tons annually and sometimes reaching 400,000 tons. This iron fueled Japan’s booming steel industry. Even a small ferry played a crucial role, transporting workers and villagers between Ho Tung Lau and the mine’s pier, where Yiu On Estate stands today. By 1963, the mine had a network of over 5,458 meters of tunnels and shafts, a testament to its complex underground world. Sadly, the Ma On Shan Iron Mines story didn’t have a fairy tale ending. In the mid-1970s, a global steel slump, combined with the discovery of large iron deposits in Australia and the end of a crucial supply contract with Japan, sealed its fate. In March 1976, mining ceased, and 400 workers lost their jobs. Today, the Ma On Shan Iron Mines stand as a silent monument to Hong Kong’s industrial past. They whisper tales of sweat, toil, and global economic forces, reminding us of the ever-changing landscape of industry.
