Pacific Empire begins drilling fifth hole at Trident

Executive Summary

• Pacific Empire Minerals Corp. has commenced drilling of its fifth hole (TRI-25-005) at the Trident copper-gold project in British Columbia, targeting the margins of a newly confirmed porphyry intrusion to vector toward higher-grade mineralization.
• Previous drilling (Holes 1-4) has successfully intersected visible copper mineralization (chalcopyrite and bornite) and confirmed a central porphyry intrusion, validating the company's geophysical model and identifying distinct intrusive phases.
• A total of 1,958 metres have been completed across four holes, with samples currently being processed at ALS Laboratories for assay results.

Key Details

• Current Drilling Activity:
  • Hole TRI-25-005 is underway, collared from the same location as TRI-25-001 but with a new azimuth of 330 degrees.
  • Objective: Test the margins of the porphyry intrusion confirmed in Hole 4 and vector toward the strong copper mineralization found in Hole 1.
• Completed Drilling Summary (1,958 metres total):
  • TRI-25-001: 503 metres.
  • TRI-25-002: 501 metres.
  • TRI-25-003: 501 metres.
  • TRI-25-004: 453 metres.
• Geological Findings & Highlights:
  • Hole TRI-25-001: Collared directly into a mineralized porphyry with disseminated chalcopyrite and visible bornite. At ~300m, it crossed a major fault zone into strongly potassic- and sericite-altered rocks, suggesting proximity to a hydrothermal center.
  • Holes TRI-25-002 & TRI-25-003: Tested an IP chargeability anomaly ~360m northeast of Hole 1; both encountered zones of visible copper mineralization with abundant pyrite, supporting a broad, continuous system extending along strike.
  • Hole TRI-25-004: Drilled to test the center of a large resistivity anomaly; successfully confirmed a porphyry intrusion. This intrusion was less mineralized (interpreted as an earlier, weakly mineralized phase) but provides essential context for vectoring toward later, copper-rich intrusive phases.
• Project Context:
  • Trident is a 100%-owned, early-exploration-stage alkalic porphyry copper-gold-silver prospect covering 6,618 hectares.
  • Located ~50 km southeast of NorthWest Copper’s Kwanika deposit and ~50 km northwest of Centerra Gold’s Mt. Milligan mine.
  • Pacific Empire acquired the property in 2022 for a 2% NSR royalty (1% of which is redeemable for $500,000).
• Next Steps:
  • Completion of Hole TRI-25-005 to better define the relationship between intrusive phases and identify potential zones of stronger copper-gold mineralization along the intrusive contact.
  • Release of assay results as they become available from ALS Laboratories.

Notable Quotes

• "Each hole drilled at Trident continues to refine our understanding of this emerging porphyry system," stated Brad Peters, president and chief executive officer of Pacific Empire. "The confirmation of a porphyry intrusion at the centre of the geophysical anomaly represents a key milestone in our exploration model. With hole 5 now under way, we're testing a new orientation that aims to follow up on the strongest copper mineralization intersected to date in hole one."
