Stillwater Critical Minerals also holds the high-grade Black Lake-Drayton Gold project adjacent to Treasury Metals' development-stage Goliath Gold Complex in northwest Ontario, which is currently under an earn-in agreement with an option to joint venture whereby Heritage Mining may earn up to a 90% interest in the project by completing payments and work on the project.
