Sego Resources Discovers Copper Porphyry Within the South Gold Zone

On December 19, 2025, Sego Resources reported a new copper porphyry discovery within the South Gold Zone at its Miner Mountain Project in British Columbia. The company completed four diamond drill holes (DDH25-66 to DDH25-69). Three of these holes intersected copper porphyry mineralization, characterized by potassic-altered microdiorite and monzonite with visible chalcopyrite. Hole DDH25-69 is noted as having the most extensive mineralized environment. All assays are currently pending. Drilling is continuing at the Cuba Zone, located 1,700 meters to the northeast.

This news is material and positive as it identifies a new mineralized style (copper porphyry) within a zone previously focused on disseminated gold. - Exploration Validation: The discovery of chalcopyrite in three out of four holes suggests the potential for a larger copper system than previously modeled at the South Gold Zone. - Pending Assays: While visual mineralization is encouraging, the lack of assay data means the economic significance (grade and width) is currently speculative. - Operational Continuity: The transition of the drill rig to the Cuba Zone for deep testing shows management is following through on the exploration plan outlined in the November 12 mobilization announcement.

Sego Resources is a junior explorer focused on the Miner Mountain Alkalic Copper-Gold Project near Princeton, B.C. The project is strategically located 15 km north of Hudbay Minerals' Copper Mountain Mine. - South Gold Zone: Known for near-surface disseminated gold. Historical highlights include 88m of 1.08 g/t Au. - Cuba Zone: Targeted for deeper copper-gold porphyry mineralization. - Royalties: The property is subject to a 3% NSR royalty. Sego retains a buy-back right for 1.5% (half) for $1,500,000.
