A few samples of sulphide rocks from Mengapur Copper Mine have been collected for the test of Acid Mine Drainage (AMD) prediction. The rock samples were characterised and subjected to two static tests. The samples contained 7.7% to 11.4% sulphur, most of which associated with pyrite and pyrrhotite. The total calcium and magnesium oxide content of the samples ranged from 1.3% to 1.6% The Acid Production Potential (APP) and Neutralisation Potential (NP) were determined by Acid Base Accounting (ABA) method via two static tests. The static tests that have been used are the BC Resean::h Initial Test and Lapakko Procedure Test. The Net Neutralisation Potential values (NP -APP) indicated that the samples were acid producers, thus have great potential for AMD to occur in the future. Using ABA values, all the samples had NP:APP ratios less than 3:1, a value proposed in California for identification of acid producing wastes.
