What this company does

The Company's wholly owned subsidiary SMMI is the sole manager of the South Mountain Project in its entirety through a separate Mining Lease with Option to Purchase ("Lease Option") with the Company's majority-owned subsidiary OGT. On January 27, 2025, the Company announced a strategic partnership with Swiss-based MFD Investment Holdings SA ("MFD"). The letter agreement signed outlines that MFD will provide additional funding, contributing $1,000,000 in project-related expenditures as well as providing technical support for project development. This partnership adds additional financial strength in advancing South Mountain's technical and economic studies. During 2025, the Company continued advancing exploration and development activities at the South Mountain Project. The Company's efforts were focused on refining drill targets through updated geophysical modeling and geochemical interpretation. The Company also continued evaluating exploration opportunities at its Trout Creek Project in Lander County, Nevada. The Company employs two full-time officers, three part-time officers and one administrative staff. It is anticipated that the employees will continue their work with the Company.
