J. B. Westerhout, ../../ (1848)
“ The mineral productions of Malacca are principally gold and tin. The Gold mines of Ophir were worked till the year 1817 by the Malays. About that time from 20 to 30 Chinese also commenced working, and have increased from time to time, so that the average number at present employed there is about 250 men. Eight Klings from the Coast of Coromandel have gone up this year, the gold is of 9 touch; the mines are at the foot of the mountain, and their general depth is from 70 to 200 feet. The Malay process of gathering the gold dust is very simple. ”
