Pacific Empire Intersects 183.0 Metres of 1.23% CuEq Starting at 9.0 Metres,
Including 71.5 Metres of 1.80% CuEq at Trident A Zone, British Columbia
December 15, 2025 – Vancouver, B .C., Canada – Pacific Empire Minerals Corp. (TSXV: PEMC) (“Pacific
Empire”, “PEMC” or the “Company”), a copper -gold explorer based in British Columbia, is pleased to announce
initial assay results from the upper portion of the first hole of its 2025 winter diamond drilling program at the Trident
copper-gold project in north-central British Columbia. These initial results, which represent only the upper portion
of Hole DD25-TRI-001, demonstrate broad, near-surface copper-gold mineralization consistent with the interpreted
A Zone porphyry system. Assays for the remainder of Hole DD25- TRI-001, together with results from five
additional drill holes completed during the 2025 winter program, are pending and represent near -term catalysts to
further define the scale, continuity, and grade distribution of mineralization at Trident. Results reported represent
the strongest copper -gold mineralization intersected at Trident to date and materially advance the Company’s
geological understanding and exploration model for a potentially significant porphyry copper-gold system.

A total of six diamond drill holes were completed for 2,603 metres across three priority target areas:
• Three holes (DD25-TRI-001, DD25-TRI-005 & DD25-TRI-006) were drilled at the A Zone, following
up on historical copper-gold mineralization and new geological modelling.
• Two holes (DD25-TRI-002 & DD25-TRI-003) tested an area 400 metres north of the A Zone , where
subsurface geophysical trends suggested potential extensions of the system.
• One hole (DD25-TRI-004) targeted a significant resistivity anomaly identified in the 2024 MobileMT
airborne magnetotelluric survey, located in the central part of the property.
“These results materially advance our understanding of Trident and are exactly the type of outcome we were hoping
for as we continue to advance the project,” said Brad Peters, President and CEO of Pacific Empire. “The A Zone
drilling has identified broad intervals of strong copper-gold mineralization from near-surface, including a substantial
higher-grade interval, which significantly elevates the exploration potential at Trident. Importantly, our step- out
drilling to the north and our test of the large MobileMT resistivity anomaly will provide critical information for the
next phase of drilling. The combination of strong copper grades, gold enrichment, potassic alteration and magnetite
is a hallmark of well-developed porphyry copper-gold systems in British Columbia, and we believe we are working
in the right part of such a system.”
Geological context indicates that Hole DD25 -TRI-001 intersected potassic -altered, magnetite-bearing porphyritic
intrusive rocks hosting copper-gold mineralization, as evidenced by elevated copper and gold values, consistent iron
content, and low lead– zinc–arsenic levels within the reported interval. While a single drill hole provides only a
limited window into the geometry of the system, the alteration and geochemical characteristics observed are
consistent with mineralization associated with a porphyry copper-gold environment. These results support continued
follow-up drilling to evaluate the lateral and vertical extent of mineralization at Trident.
From surface to approximately 77 metres depth, Hole DD25- TRI-001 intersected a continuous sequence of
monzodiorite and hornblende–feldspar porphyry, characterized by fine- to medium-grained, crowded feldspar-phyric
textures. These intrusive rocks display consistent potassic alteration, marked by fine biotite, abundant magnetite, and
localized K -feldspar mottling. Copper mineralization occurs primarily as disseminated and fracture -controlled
chalcopyrite ± pyrite, with locally observed bornite, indicating locally higher copper intensity, and is commonly
associated with narrow quartz–magnetite veinlets. This alteration and mineralization assemblage is characteristic of
the central to proximal portions of an alkaline copper –gold porphyry system. Importantly, the recognition of
porphyritic intrusive phases —whether mineralized or weakly mineralized —is a critical element in porphyry
exploration, as such intrusions define the plumbing architecture of the system and provide key vectors toward higher-
grade or more str ongly mineralized domains. No major lithological or alteration breaks were observed within this
near-surface interval, and a locally higher -grade, gold-bearing veinlet occurs within the broader copper -rich zone,
highlighting the potential for gold-enriched domains within the Trident system.

near surface to 192.0 metres down hole, including multiple higher-grade internal zones. The results highlight the scale and continuity of
mineralization within the Trident porphyry system and provide important context for follow-up drilling.
Drill intercepts reported herein are based on down -hole lengths. At this stage of exploration, the true thickness and
orientation of the mineralized zones are not yet known. Additional drilling and geological modelling will be required
to determine the true width of the reported mineralization.
CuEq Calculation
Copper equivalent (“CuEq”) values are calculated using the following metal prices: US$5.00/lb copper, US$3,000/oz
gold, and US$35.00/oz silver, with assumed metallurgical recoveries of 92% for copper, 88% for gold, and 85% for
silver.
The CuEq calculation is intended to express the combined value of copper, gold, and silver mineralization within
individual drill intervals on a consistent basis and is provided for illustrative purposes only. No metallurgical testing
has been completed at this stage, and the Company cautions that actual recoveries may differ from the assumptions
used.
Metal prices used in the CuEq calculation reflect an elevated commodity price environment, are conservative relative
to recent spot prices, and are intended solely for comparative purposes.

Challenging Winter Conditions
Drilling during this winter program required significant operational flexibility. Following a period of sustained sub-
zero temperatures and snowfall, a rapid shift to warm, wet weather created difficult access conditions, particularly in
the central resistivity target area where road surfaces deteriorated quickly. When temperatures again dropped below
freezing, sections of the access trail developed hard ice on steep slopes, requiring additional safety measures and
rerouting. Despite these challenges, Omineca Drilling maintained excellent productivity and safely completed all
planned holes, drilling a total of 2,603 metres, exceeding the originally planned 2,500-metre program.
Ongoing Work
Assays from the remaining holes are pending and will be released once received and reviewed. Results to date are
being used to refine geological and geophysical vectors for follow -up drilling. Geological interpretation, 3D
modelling, and integration of MobileMT data with drilling results are currently underway.
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 the 2025 winter drill program now complete and additional assays
pending, PEMC is well positioned to advance Trident toward wha t could be a significant gold- enriched copper
porphyry discovery.
Quality Assurance and Quality Control
Quality assurance and quality control (QA/QC) procedures included the insertion of certified reference materials,
blanks, and preparation duplicates into the sample stream. QA/QC samples were submitted as blind samples to the
laboratory. The results indica te acceptable analytical accuracy and precision, with no evidence of significant
contamination.
Diamond drill core was recovered using NQ-sized core. Core was logged for lithology, alteration, mineralization, and
structure prior to sampling. Samples were collected on nominal 1.5- metre intervals, adjusted as required to respect
geological boundaries. All samples consisted of half-core, with the remaining half retained for reference and potential
future analysis.
Analytical Procedures
Sample preparation and analysis were conducted by ALS Canada Ltd. at its sample preparation facility in North
Vancouver, British Columbia, with analyses performed at ALS laboratories in Vancouver, British Columbia, and
Lima, Peru. ALS laboratories are inde pendent of the Company and are ISO/IEC 17025 accredited for the analytical
methods employed.
Core samples were prepared using ALS method PREP -31A, which includes crushing and pulverizing to produce a
