Pacific Empire Announces Completion of Mobile
MagnetoTelluric Survey at Trident and Pinnacle
April 1 , 202 4 – Vancouver, BC, Canada – Pacific Empire Minerals Corp. (TSXV: PEMC) (“Pacific
Empire”, “PEMC” or the “Company”), a British Columbia copper -gold explorer, announces Expert
Geophysics Ltd. (“Expert”) has now completed an airborne MobileMT ™ survey at its 100% owned
Trident and Pinnacle copper-gold projects in the South Hogem Copper-Gold Belt.
Highlights
• The completed survey totals 164 line-kilometres and provides coverage of primary target area at
its Trident property (historical assays at Trident which include DDH -1971-13: 70.07m @ 0.69%
Cu, DDH 2007-2: 100.00m @ 0.59% Cu and 0.18 g/t Au including 2.00m @ 2.73% Cu and 0.36
g/t Au).
• The MT survey also cover ed an additional target located on PEMC’s 100% owned Pinnacle
Property situated directly west and adjacent to the Trident. Utilization of this modern geophysical
dataset will facilitate the identification and prioritization of target areas for drilling curre ntly
anticipated during the Summer/Fall 2024 exploration season.
• MagnetoTelluric (MT) survey method capable of detecting basement electromagnetic (EM)
conductors and anomalous resistivity zones which are indicative of potential copper-gold porphyry
systems.
“We anticipate preliminary data and preliminary results in the coming days ,” commented Brad Peters,
President, CEO & Director of Pacific Empire. “This will be followed by a series of digital data sets which
will be followed up with complex data analysis and targeting by our technical team and the team at Expert
Geophysics. Copper bearing porphyry systems are an ideal target for MobileMT. Fault contacts and fault
associated conductive zones, highly resistive wedges of mineralizing intrusions and potassic alteration
zones are very well identified and defined using the MobileMT exploration technique with great spatial,
depth and resistivity r esolution. We look forward to being able to see to depths of over one kilometre
beneath the surface at our 100% owned Trident and Pinnacle projects, west of Centerra Gold’s operating
Mount Milligan copper-gold mine. Our objective is to identify potential “plumbing systems, “because if
you are looking for large copper deposits you need a large plumbing system.”

Mobile MT Survey
The purpose of the survey is to identify conductivity /resistivity anomalies that may represent conduits for
hydrothermal fluids critical in the formation of porphyry copper-gold deposits. These conduits have the
potential to represent critical plumbing systems responsible for the formation of copper porphyry deposits.
The gathering of both resistivity and conductivity imaging of the surface to a depth of 1 km through
deploying an airborne MobileMT (Mobile Magneto Tellurics) system will provide key information
pertaining to source fluid conduits and structures. This important step will provide valuable insights and
aid to further both know n and unknown exploration targets destined for follow up diamond drilling
programs.
In addition, complimentary VLF (Very Low Frequency) data will be collected and interpreted to provide
valuable near surface EM (Electromagnetic) information. The survey conducted approximately 164 line-
km’s using a 200 m line spacing grid.
The final data processing, colour imaging and mapping will be performed at EGL’s offices in Toronto,
Canada. Final results and resulting products are expected to be available to the PEMC exploration team
over the coming weeks.
About Mobile MagnetoTelluric Surveys
The latest development in the airborne MobileMT system, provides a depth of investigation from the near-
surface to over 1 km and detects resistivity variations across a wide range, encompassing conductive targets
and structures as well as highly resistive ones.
Porphyry and epithermal mineralization systems develop in conditions of active subduction and they are
characterized by a wide variety of structural, lithological, and alteration patterns, which, at least partially,
can be depicted in geoelectrical images.

The following two examples demonstrate the effectiveness of resistivity mapping and sounding using the
MobileMT system. Both examples from MobileMT surveys are presented over areas with known porphyry
and epithermal mineralization systems and mineralization-controlling structures. The recovered resistivity-
depth images are compared with actual geology or conceptual geological models of the mineralization
systems, which illustrate the system's capabilities in imaging the mineralization systems and their diverse
geometries and wide resistivity range.

About Trident
The Trident property is an 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 to the southeast of North West Copper Corp.’s Kwanika Deposit 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 for exploration programs.
Copper mineralization on the property was first discovered in 1969, while exploration crews were
following up on anomalous st ream sediment samples. The following year , Falconbridge optioned the
property and over the next two years completed IP and magnetic surveys, geological mapping, soil
sampling and diamond drilling. This work led to the discovery of the A Zone.
Additional exploration programs were completed by Kookaburra Gold Corp. from 1988 through 1991,
Solomon Resources Ltd., from 2006 through 2008. In 2013, PEMC optioned the property and in 2014, in
turn, PEMC optioned the property to Oz Minerals which completed that same year an IP survey and
completed a two drillhole, diamond drill program at Trident.
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 may be purchased for $500,000 by
Pacific Empire.
Prior to 2014, known mineralization on the property was believed to be associated with fracture and/or
shear zones structures striking 120 degrees and dip ping 75 degrees to wards the northeast. A review of
historical drill core by the Pacific Empire exploration team has led to a much different interpretation with
respect to the nature of known mineralization on the property. The most important observation was the
determination of the presence of hornblende-feldspar monzonite porphyry intrusions detected within drill
core obtained from the A Zone. These types of porphyry intrusions are typically characterized by sheeted
quartz sulphide veins and disseminated chalcopyrite and bornite residing immediately adjacent to and
within the porphyry dikes. Other observations include; The highest grades noted in historical drilling can
be seen to be directly associated with intervals where such porphyry intrusions occur.

“Between our 100% owned Trident and Pinnacle projects runs the Klawli river. The gold flakes and nuggets
in the vial displayed on the map were collected from that location on the Klawli river. It is this and other
geochemical evidence gathered by the PEMC exploration team which leads us to postulate the potential for
a gold-enriched copper system nearby on either Trident, Pinnacle, or possibly both projects. To date, visible
gold has been observed in outcrop at Trident, placer gold discovered in the nearby Klawli river gravels,
and as well gold detected in drill core from Pinnacle. All three of these known occurrences of gold and their
respective locations suggests there may be a shallow buried, large scale, gold-enriched, copper porphyry
deposit within our district scale land package ,” commented Brad Peters, President , CEO and Director of
Pacific Empire.
