Pacific Empire Minerals Corp. (TSX-V: PEMC), a copper-gold explorer based in British Columbia, is pleased to announce the closing of the second and final tranche of its non-brokered private placement and the arrival of Omineca Drilling Ltd. to commence diamond drilling at the Company’s flagship Trident Copper-Gold Project in north-central British Columbia.

Second Tranche Closing

Further to news releases dated September 17 and October 7, 2025, the Company has closed the second and final tranche of its Offering for gross proceeds of C$140,702, bringing the total raised to C$1,526,991.95.

Under this final tranche, PEMC issued:

• 22,999,770 Hard Dollar Units at C$0.035 per unit; and
• 18,050,000 Flow-Through Units at C$0.04 per unit.

Each Hard Dollar Unit consists of one common share and one common share purchase warrant exercisable at C$0.05 for two years. Each Flow-Through Unit consists of one flow-through common share and one warrant exercisable at C$0.06 for two years.

Finder’s fees for both tranches totaling C$56,611.94 in cash and 1,539,984 finder warrants were paid to eligible parties including Haywood Securities Inc., Canaccord Genuity Corp., Research Capital Corp and Raymond James Ltd. All securities are subject to a four-month hold period under applicable laws.

Proceeds will be used to fund exploration activities at Trident and for general working capital.

Drilling To Commence at Trident

PEMC is pleased to report that Omineca Drilling Ltd. has arrived at the Trident camp, with diamond drilling set to commence today. The 2025 program is fully permitted and will include five holes totaling approximately 2,500 metres, designed to test both porphyry and breccia targets that have never before been drilled despite decades of historical exploration in the area.

The targets lie along the contact between the Hogem Plutonic Suite and the Chuchi Lake volcanic succession — a geological setting that hosts numerous copper-gold porphyry deposits across British Columbia.

Brad Peters, President & CEO of Pacific Empire, commented: “With Omineca Drilling on site and the final tranche now closed, we are thrilled to begin the first-ever diamond drill program on the current target area at Trident. This is a pivotal moment for Pacific Empire and our shareholders — the culmination of years of systematic work and the start of what we believe could be a transformational discovery program.”

 Figure 1 – Map showing Pacific Empire’s fully permitted work area at Trident, including historical drill collars and the five planned 2025 drill holes. Nearly 80 historical holes have been completed south of the creek, yet the newly permitted northern area — long considered the most prospective ground — has never been drilled. With access, camp, and trails now established, Pacific Empire is positioned to be the first company to test these high-priority porphyry and breccia targets.

 Figure 2 – Compilation map of the Trident property showing multiple independent datasets converging on a major discovery opportunity. A large porphyry target is outlined by copper and gold soil anomalies, resistivity and chargeability features, and favorable intrusive-volcanic contacts. Flanking this centre, conductivity highs define undrilled breccia targets supported by strong copper geochemistry. Together, the data outline a system-scale copper-gold target that has never been tested.

 Figure 3 – A highly anomalous copper-in-soil anomaly defines the primary porphyry target at Trident. On a moderate slope, the source of the anomaly is most likely located near its upper extent — precisely where drilling is planned. This anomaly, combined with supporting geophysics and geology, makes Trident one of the most exciting undrilled porphyry copper-gold targets in British Columbia.

Unlocking Untested Ground

Although nearly 80 drill holes have been completed at Trident since the 1970s, none have tested the northern porphyry and breccia targets. Historically, access to this area was prevented by the need to cross a creek, which required significant planning and permitting. With PEMC’s recently granted Multi-Year Area-Based Exploration Permit, the Company is now positioned to drill this area for the very first time. This makes the 2025 program a true milestone in the project’s history — opening ground that has long been considered the most prospective but remained completely untested.

Strategic Importance

The Trident drill program comes at a time when global copper demand is accelerating due to electrification, grid expansion, and electric vehicle adoption. At the same time, new large-scale copper discoveries have become increasingly rare, underscoring the importance of exploring in proven, mining-friendly jurisdictions such as British Columbia. With gold also consistently present as a by-product credit in the system, Trident has the potential to deliver the combination of size, grade, and precious metals that makes porphyry copper-gold deposits particularly attractive.

Pacific Empire believes the 2025 drill program represents a critical opportunity in the Trident property’s 50-year history of exploration. The combination of historical mineralization at the A Zone, overlapping geophysical and geochemical anomalies at the porphyry target, and newly permitted access to never-before-drilled breccia targets creates a unique discovery opportunity. With drilling scheduled to begin in September 2025, PEMC is well positioned to advance Trident toward what could be a significant gold-enriched copper porphyry discovery.

About Trident

The Trident property is an early exploration stage property hosting an alkalic porphyry copper-gold-silver prospect with district-scale potential that is accessible by vehicle. The property is located approximately 50 km southeast of the Kwanika deposit owned by

NorthWest Copper Corp. and 50 km to the northwest of Centerra Gold’s Mt. Milligan Mine. The property covers 6,618 hectares endowed with well-established logging roads providing important efficient access to conduct exploration programs.

In 2022, Pacific Empire acquired a 100% interest in the property in exchange for granting the vendors a 2% net smelter return royalty (“NSR“). One-half (1%) of the 2% NSR which may be purchased for $500,000 by Pacific Empire.

About Pinnacle

The Pinnacle project is located 60 km west of Centerra Gold’s Mt. Milligan Copper-Gold Mine and 30 km southeast of NorthWest Copper’s Kwanika Copper-Gold Deposit in a proven copper-gold porphyry district. Access to the Pinnacle is by road including a new and expanding network of logging roads and trails throughout the main target areas. This improved access is a significant development and is anticipated to contribute to cost effective drill support and provides additional bedrock exposure.
