Do you see those overgrown hillsides? They conceal a story of ambition, labor, and a valuable metal. This is Needle Hill Mine, once a bustling center for tungsten extraction.
Needle Hill Mine’s history stretches back over a century. Mining here began around 1917. The focus was on wolframite. It is the ore from which tungsten is derived. Tungsten is incredibly strong. It has a high melting point. It was used in electric filaments. It was also used in armor-piercing ammunition. This made it strategically important, especially during conflicts.
Early mining operations were basic at Needle Hill Mine. Miners used water to wash away soil. This exposed the mineral veins. They dug short tunnels called foxholes. By the end of 1917, about 200 workers were employed at Needle Hill Mine.
In 1921, a report highlighted the discovery of tungsten-bearing ore. Six outcrops were found in the New Territories. Three were actively developed. The US Consul-General even suggested these deposits could be globally significant. By 1919, the Needle Hill Mine output averaged about 30 piculs of wolfram ore per month. A picul was a practical measurement. It was about 60.5 kg. It represented what a man could carry on a shoulder-pole.
After World War I, demand for tungsten decreased. The Needle Hill Mine changed hands. It passed from an Anglo-American syndicate to local residents. In 1929, Mr. J. P. Kim applied for a mining license. He represented the National Commercial Company Ltd. Kim’s team mapped mineral veins. They excavated new tunnels to assess the ore’s size and quality.
In 1936, Marsman Investments Ltd. acquired a 21-year lease for Needle Hill. Marsman Hong Kong China Limited was later formed. G. B. Gifford Hull, the engineer behind the Shing Mun Reservoir, became the Managing Director. By 1938, Needle Hill Mine had extracted 1,640 piculs of wolframite.
Life at the Needle Hill Mine was tough. In 1938, around 500 workers were employed here. They included men, women, and children. They lived in purpose-built accommodations. Subcontractors ran the mine. They operated different adits.
During World War II, the Japanese took control of the Needle Hill area. They reopened the mine in 1942. They extracted 10 to 12 tonnes of wolframite ore monthly for shipment to Japan.
After the war, illicit mining resumed. Marsman regained control in 1947. They planned to modernize operations. In 1953, they partnered with Hoong Foo Mining Company Ltd. Production reached 250 kg per day.
However, declining wolframite prices led to the Needle Hill Mine’s closure in 1955. Yan Hing Mining Company Ltd. took over in 1956. In 1967, the mine finally ceased production due to low prices and rising wages.
Today, the adits of Needle Hill Mine lie hidden. They are overgrown with vegetation. These tunnels are dangerous. They serve as a reminder of Hong Kong’s industrial past. It operated for 50 years. Over 200,000 tonnes of ore were removed. This yielded nearly 1,500 tonnes of wolframite ore. The total value extracted was around HK$140 million. A significant sum.
As you look around, remember the thousands of workers. They toiled here in difficult conditions. The Needle Hill Mine played a vital role. It contributed to Hong Kong’s development.
