Agreements were signed so that "Mr Helms and Mr Ruppell were to rule the foreign portion of the town [Kuching], and the Datu Bandar the Malays, under the [gold miners’] Kongsi as supreme rulers.” and “the Chinese should go up the river the same day … the Malays should not attack them … no steamers or boats should be sent up the river in pursuit.” On 23 February, BCL steamship named Sir James Brooke returned from Singapore.
[5] Building upon the victory, Tuan Muda Charles Brooke led several hundreds of Dayaks from Skrang and Saribas in pursuit of the 2,000 Chinese gold miners that retreated to Sambas, Dutch Borneo.
On the order of James Brooke, Helms went to Dutch Borneo to seek cooperation to exterminate the remaining Chinese gold miners.
The gold deposits in Bau Township occur in the Jugan Hills in marine sedimentary rocks of late Jurassic to early Cretaceous age, primarily limestone.
[15] The gold is found in four distinct configurations: disseminated throughout the mineralized sediments; as silica replacement; in breccias having magno-calcite quartz veining; and occasionally as porphyritic skarns.
[14][16] The limestone cliffs in the area support a wide range of endemic flora, including the rare pitcher plant Nepenthes northiana.
