Coal was first reported in Brunei Darussalam near
Muara as early as 1837. in Serai Pimping. The Muara coalmine was first mined commercially in 1883, when
William Cowie was given the concession rights to mine the coal in exchange for $1,200 per year. However, Cowie later sold his rights to
Rajah Charles Brooke and the Rajah renamed the
mine Brooketon (Brooke Town). Between 1889 and 1924, it was operated by the
Sarawak government of Rajah Charles Brooke. Annual
exports of coal varied between 10,000 and 25,000
tons annually and in those 33 years of operation, more than 650,000 tons were exported. At first it was
opencast until it became harder and
underground mining was introduced. Brooketon Colliery was strategic as it was very near to Muara where then and now there is a safe deep-water anchorage to which the mine was connected via rail. During the time the mine was in operation, there was a wooden rail line that connected Brooketon which is about one and a half mile away from Muara. The rail line is no longer in place. Politically too, even though he only had economic rights, Brooke became the de facto ruler of the area. The mine employed hundreds of miners and that required him to introduce a police force, post office and roads transforming Muara into an
extraterritorial settlement an extension of
Sarawak. It was not until 1921 that Muara was "returned" to
Brunei. It closed down in 1924 because of heavy financial losses caused by continuously decreasing coal prices in the world
economic recession. ==Current Issues==
