Although the early miners suffered a high death toll due to the malarial conditions of the jungle, the Ampang mines were successful, and the first tin from these mines was exported in 1859. At that time, Sutan Puasa was already trading near Ampang. Two traders from Lukut, Hiu Siew and Yap Ah Sze, then arrived in Kuala Lumpur where they set up shops to sell provisions to miners in exchange for tin. The town, spurred on by tin-mining, started to develop centred on Old Market Square (Medan Pasar), with roads radiating out towards Ampang as well as Pudu and Batu (the destinations became the names of these roads) where miners also started to settled in, and Petaling and Damansara. The miners formed gangs among themselves; and fights between different gangs were frequent in this period, particularly between factions of Kuala Lumpur and Kanching, mainly to gain control of the best tin mines. Leaders of the Chinese community were conferred the title of Kapitan Cina (Chinese headman) by the Malay chief, and Hiu Siew, the early Chinese trader, was chosen as the first Kapitan of Kuala Lumpur. The third Chinese Kapitan of Kuala Lumpur, Yap Ah Loy, was appointed in 1868.
