O3 Mining (TSXV: OIII) completed a preliminary economic assessment (PEA) of its Marban gold project in Quebec after only four months, and is on track to start a prefeasibility (PFS) study in 2021 and complete it by 2022. The company, which was spun out from Osisko Mining (TSX: OSK) in early 2019, was able to fast-track Marban because more than $60 million had been invested in the asset before Osisko acquired it in 2016, including over 600,000 metres of drilling, at least six metallurgical studies, as well as some geochemical analysis in the ore and waste rock.
