Lin Ma Hang Lead Mine [????- ]

This brief history of the Lin Ma Hang Lead Mine does not attempt to cover the geology or mineralogy of the area or mine, nor details of the mine workings. For a very full account, which includes this information plus photographs, and further references, try The Story of Lin Ma Hang Mine as shown in Source 1 below.

Lead was discovered in the Ling Ma Hang/Sha Tau Kok area in the 1860s. Old workings from this period have been found within 1km of the main mine. The lower workings of the mine, known as the Portuguese Workings, were operated in the 19^th century.

The main vein was discovered in 1915 by local Chinese miners searching for limestone.  The galena deposits proved to be the largest in Hong Kong. A mining company was formed in 1917, but only operated for three years. A 75 year mining lease, Mining Lot No. 3, was issued in 1925, backdated to 28^th June 1922, to Morrison Brown Yung.

The mine changed hands in 1932 presumably as a result of Morrison Brown Yung’s death in that year. For a short time the mine was operated by a Chinese firm who only extracted a small quantity of high grade ore.

A public listed company, Hong Kong Mines Ltd, was incorporated in Hong Kong on 18^th November 1936. The mining lease was transferred to this company on the 18^th March 1937.

However in January 1937, general management of the company had been taken over by an  American firm based in the Philippines, Neilson & Co Inc, and L R Nielson was appointed Chairman of Hong Mines Ltd.

Major development of the mine occurred which included construction of a processing plant, workshops, stores, an office and housing for the staff. In 1938 Hong Kong Mines employed a labour force of 500, of whom 350 worked underground and 150 on the surface.  It was during this period that the mine produced the most ore, between 150 and 225 tons per day. (From the First World War until 1940 annual output of lead exceeded 3,000 tons.) Further development work was undertaken, but mining was suspended in 1940 with the outbreak of war.

Small-scale mining was carried out in a haphazard way during the Japanese occupation from 1941 to 1945. This was done mostly by robbing pillars in the eastern section of the mine, which resulted in the roof caving in and making it generally unsafe.  Most of the equipment was removed during this time and the buildings were looted and damaged but probably not by the Japanese.

After the war the mine continued to be looted and it remained effectively abandoned until 1^st October 1951 when the Colonial Secretary  approved its re-opening. From 1951 until 1954 various contractors were employed after the company decided not to undertake its own operations. Output did not exceed 750 tons per annum.  From 1^st November 1951 to 30^th April 1952 the mine was operated under contract by Tonley & Co. In February 1953 a new contractor Foo Yuen & Co signed an agreement.  Eleven men worked underground and the same number above. The mining method was entirely manual.  L R Nielson visited the mine in December 1953 and was displeased with the bad mining practices he found, “showering the men with cursings and swearings.”

In September 1954 Hong Kong Mines decided to resume direct mining operations.  However, attempts to give new life to the mine were unsuccessful -  labour disputes, strikes, typhoon damage, and falling lead prices led to a supposedly, temporary closure of the mine on the 30^th June 1958, with about 60% of the reserves mined. The HK Government rescinded the mining lease in April 1962 and on the 13^th the formal order for re-entry  was registered thus ending Hong Kong Mines Ltd’s rights over the property. The mine was abandoned the same year.

Lin Ma Hang lies within the Frontier Closed Area and is  therefore  inaccessible to non-permit holders. (This may change as the border area opens up to development.) It is apparently possible to go a short distance into the underground workings where a cavern can be seen and maybe into a lower gallery. There are also the remains of the processing plant and spoil heaps.

The mine now holds one of the most important bat colonies in Hong Kong and was designated as a Site of Special Scientific Interest (SSSI) on 13 August 1994.
