The magmatic sulfide deposits in the Central Asian orogenic belt are hosted in a series of mafic-ultramafic intrusions in the Maksut zone (E Kazakhstan), the Kalatongke and the Huangshan zones in Xinjiang (NW China) and the Hongqiling zone in NE China. In the Maksut zone there are several intrusions, the best studied from which is the South Maksut intrusion with Cu-Ni-PGE mineralization.The South Maksut Ni-Cu deposit contains 0.08 Mt nickel and 0.1 Mt copper with average grades of 0.4 wt. % Ni and 0.5 wt. % Cu, respectively (BAST, 2017). Since the South Maksut Ni-Cu sulfide deposits were discovered in the 1970s, many studies have been carried out [Khromykh et al., 2013]. This paper focuses on noble metal concentrations and mineralization of the South Maksut sulfide ores and crust of weathering, which is located on the eastern part of massif (Fig. 1).Deposit geology and petrography. Early studies showed that the pluton is a small lopolith-like body [Ermolov et al., 1983;Khromykh et al., 2013]. The Maksut intrusion is mainly composed of olivine dolerite, olivine norite, and gabbronorite ( Fig. 1, a). Olivine dolerite displays ophitic and poikilophitic textures. It consists of olivine with f=20-24 (10-20 %); two generations (60-70 vol. %) of plagioclase: 85-55 % An and 40-25 % An; clinopyroxene as subcalcic augite with f=30-40 (10-25 %); biotite (3-4 vol. %);
