Marigold Mine team outlines Buffalo Valley expansion plans and feasibility study updates

The Lander County Commissioners' meeting on April 24, 2025, featured a significant update from SSR Marigold regarding its operations and future projects, particularly the Buffalo Valley project.

Richard Zogel, the study manager at Marigold, along with environmental manager Jesse Barto and general manager Anton Krueger, provided insights into the mine's history and current status. The Marigold Mine, which began operations in 1988, has evolved from a small mill operation to a large-scale open-pit mine utilizing heap leaching techniques since 1999. Currently, the mine employs approximately 485 people and has recently celebrated the production of its five millionth ounce of gold.

The presentation highlighted the Buffalo Valley project, located southwest of the Marigold Mine. This historic site is undergoing a pre-feasibility study, with plans to advance into a feasibility study by early 2026. The project aims to secure permits by the end of 2025, with construction anticipated to begin in 2028 and production expected to start in 2029. The Buffalo Valley project is seen as a promising opportunity for future growth, with initial reserve ounces already declared.

Key aspects of the Buffalo Valley project include the construction of a new heap leach facility and a road to connect it with the Marigold Mine. The project will also involve extensive environmental studies, including assessments of sage grouse habitats and groundwater conditions. The company is committed to minimizing public land access disruptions and ensuring effective reclamation strategies post-mining.

The meeting concluded without public questions, but the update underscored the ongoing development and potential expansion of mining operations in Lander County, reflecting the area's economic prospects and environmental considerations.
