Brooketon Colliery

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.

[2] 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 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 closed down in 1924 because of heavy financial losses caused by continuously decreasing coal prices in the world economic recession.

[2] It is currently already a protected site under the Antiquities and Treasure Trove Act of Brunei Darussalam.
