The Bhukia-Jagpura gold prospect is hosted by a Paleoproterozoic metasedimentary rock sequence that constitutes the lowermost part of the Aravalli Supergroup, lying in close proximity to the basement-cover contact. A combined ore petrographic, LA-ICPMS and EPMA studies of iron sulfides and sulfarsenides from the prospect has revealed four varieties of pyrite and two varieties of arsenopyrite with different trace element compositions. The data indicates a sedimentary-diagenetic origin for the earliest Pyrites (Py) I and II, which are devoid of any gold, in contrast to hydrothermal Py III and IV with a minor, but significant content of invisible gold (0.3–1.6ppm). Associated loellingite (35–51ppm) and Arsenopyrite (Aspy) I (0.28–10ppm) contain the maximum concentration of invisible gold, while it is substantially lower in Aspy II (0.06–1.5ppm). The compositions of the gold-bearing pyrites (low Ni:Co ratios …
