Marban is an open-pit development project owned and operated by O3 Mining Inc. (“O3”). The Marban property is located in the western portion of the province of Quebec, Canada, approximately 15 kilometers northwest of Val-d’Or. The property lies at the junction of Dubuisson, Fournière, Malartic and Vassan townships. 

The Marban property is divided into two projects: Marban Alliance, the southeast portion of the property; and Horizon, which is broader and includes all the north and west parts of the Marban property. Royal Gold’s royalty covers only a portion of the Marban Alliance and Horizon properties but includes the Marban open-pit target, which is the subject of the current technical studies.

Marban Alliance has been the subject of multiple technical studies during its development, including a Preliminary Economic Assessment in 2020 and a Prefeasibility Study in 2022. O3 expects to commence a Feasibility Study in the first half of 2024.

The project is being developed as a stand-alone operation with all necessary infrastructure, including open-pits, gold processing plant, tailings processing facilities, waste rock storage areas and all necessary access and production roads.
