Indonesia is a country rich in natural resources, one of which is gold deposits scattered across several locations, including the islands of Sumatra, Java, Sulawesi, Maluku, Nusa Tenggara and Papua.  This study aims to (1) determine the type of alteration contained in the research area based on the altered mineral set resulting from the alteration process and the characteristics of gold deposits in metamorphic rocks in the study area, (2) determine the mineralisation characteristics of gold deposits by conducting geochemical analysis, (3) determine the type of metamorphic facies in host-rocks Gold deposits in the research area, (4) explain how the distribution of gold content from the results of geochemical analysis, (5) explain the genetic characteristics of gold deposits in the study area based on geochemical analysis and petrographic analysis. This study involved a field survey and random rock sampling at Mount Botak, Buru Regency, Maluku Province, Indonesia. Rock samples were analysed by petrographic analysis, XRD (X-ray Diffraction) analysis, XRF (X-ray fluorescence) analysis, ICP-OES (inductively coupled plasma-optical emission spectrometry) analysis, and AAS (atomic absorption spectrometry) analysis. The study results indicate that the host rock of gold deposits on Buru Island is a metamorphic rock formed by greenschist facies. The types of alterations are silicic, sericitization, argilic, and chloritization. The mineralisation is generally in quartz veins with a crustiform texture and a slight vein stockwork. Au levels ranged from 0.23 to 5.9 g/ton, which was not accompanied by Ag enrichment. Based on the analysis of gold deposits in the research area, it is an orogenic-type of deposit formed in a mesozonal environment, typically at a depth of 5-10 km. The implications of the research results can be applied to gold exploration purposes in Indonesia, particularly for gold deposits that have metamorphic host rocks.
