In 1857, Raja Abdullah, a representative of the Selangor Sultanate, opened up the Klang Valley for tin mining.[1] 87 Chinese miners from Lukut went up the river Klang and landed at Kuala Lumpur, then walked for a few miles through a jungle path to Ampang and began prospecting in the Ampang area. However, within a month 69 of the 87 miners had died due to the malarial conditions of the area, and Raja Abdullah sent another 150 men to continue the work. Eventually the death rate dropped, and the first tin was exported in 1859.
