The Tongkah Harbour organization has been in mining for 105 years beginning with offshore tin mining in and around Phuket Bay in 1906.
The Company was the brainchild of Captain Edward T. Miles of Australia who, upon observing the labor intensive methods of Chinese in offshore
mining at Phuket in 1905, felt that he could develop equipment to mechanize the industry.
Tongkah Harbour Public Company Limited was established since 1906 by Captain Edward Thomas Miles, an Australian businessman. Tongkah first invented a tin dredger innovation in Thailand and in the world. From that, Captain Edward was granted a license for tin mining in Phuket bay from the government and had increased the production capacity with 7 extra ships covering 6,205 acres of the explorations and operations in the Phuket area in Chalong Bay, Bang Tao Bay, and Phuket Bay over 7 decades
In 1980 - 1981,
The Company was registered as a listed company in the Stock Exchange of Thailand under the name of “Tongkah Harbor Public Company Limited”, which was entirely owned by the Thais. The Company has initiated stocks trading in SET ever since.
