The Sabah Fe ore deposits are located in Al-Bayda\'a area, about 220 km SE of Sana\'a Capital City. Iron associated and confined in marble beds and meta andesite. Mineralogical studies by XRD analyses and petrographic examinations under reflected light of iron ores show they are composed essentially of magnetite and hematite minerals.The results of chemical analyses for iron ore in the Sabah area show that, the iron oxide ranges from 64.3% to 86%, with an average of 76.7%, and iron has an average 57.5%.The Magnetic map of Al-Bayda\'a ? Mukayras block illustratedlarge and clear anomaly of ore deposit. The band ratio 5/4 of ETM+ and ASTER highlight rocks rich in ferrous iron as bright pixels compared to other rock units.The band ratio 3/1 of ETM+ highlight iron oxides as bright pixels. The band ratio 5/7 of ETM+ and its equivalent 4/6 of ASTER image highlighted the regions which are dominated by the hydroxyl and silicate-bearing rocks as bright pixel.
