Archaeological excavations carried out on 17 iron smelting workshops at the Sungai Batu Archaeological Complex have found the raw materials of iron industry (hematite, magnetite and geotite) with iron slag, tuyere, remains of furnace, and iron ingots. In order to obtain primary data related to the location of the raw materials of iron smelting obtained, the survey and mapping activities were carried out using geological maps and Sungai Petani maps around UiTM Merbok, Bukit Inas, Merbok, Batu 5 Village, Paya Suri Village and Ayer Nasi Hill, Semeling. The results of the iron ore survey were then subjected to scientific analysis to compare the mineral composition with the findings of iron ore at the iron smelting site. The results of X-Ray Fluorescence (XRF) analysis of iron ore for major elements reveal the elements silica oxide (SiO₂), iron oxide (FeO₊), manganese oxide (MnO), calcium oxide (CaO), aluminum oxide (Al₂O₃) and titanium oxide (TiO₂) as well as arsenic (As), Chlorine (Cl), copper (Cu), scandium (S), vanadium (V) and zinc (Zn) for trace elements clearly show the raw material of iron smelting in the Archaeological Complex Sungai Batu is from the same source. Based on the analysis of the raw materials of iron smelting to enable the iron smelting industry in the Archaeological Complex to take place is taken from a distance of 1-11 km from this complex.
