We examine the metallogenic epochs of the Barama-Mazaruni Greenstone Belt, focusing on orogenic gold deposits, lithium exploration in LCT pegmatites, and the transformative 2026 Mineral Inventory mapping project currently underway in the Stabroek block and the interior. The northern region is primarily defined by Paleoproterozoic Orosirian greenstone belts intruded by syn-to-late tectonic granitoids during the Trans-Amazonian Orogeny, a process that facilitated significant mineralization at sites like the 9 Mile Deposit and the Karouni gold deposit (Bassoo & Murphy, 2018; Tedeschi & Hagemann, 2018; Wikipedia, 2025). Advanced exploration data from the Guyana Geology and Mines Commission (GGMC) reveals untapped potential for magmatic Ni-Cu-PGE deposits and critical minerals including tantalum, niobium, and rare earth elements (Lowe, 2013; International Trade Administration, 2026). While the Liza oilfield discovery has triggered a historic economic boom, the government is utilizing oil revenues to fund a national-scale aerial mineral mapping project intended to diversify the economy before the global energy transition matures (Bloomberg Originals, 2024; Guyana Geology and Mines Commission, 2025). Geochemical studies further highlight the secondary enrichment of REEs and vanadium in lateritic duricrusts and the significant industrial reserves of kyanite in the Supenaam Basin (Ansart et al., 2022; Vieira, 2014). This video provides structural geologists and ore prospectors with a deep dive into the geochemical discrimination of IOCG versus orogenic systems and the long-term mineral endowment of this emerging mining powerhouse (James et al., 2025; Lowe, 2013).
