Greenridge Exploration Initiates Ground Gravity Survey at the Carpenter
Lake Uranium Project, Athabasca Basin Area
April 27, 2026
Vancouver, B.C. – Greenridge Exploration Inc. ("Greenridge" or the "Company") (CSE: GXP |
OTC: GXPLF | FRA: HW3), is pleased to announce the commencement of a ground geophysical
program (the “Program”) at its Carpenter Lake Uranium Project (“Carpenter Lake”, or the
“Property”), located on the southern margin of the Athabasca Basin in northern Saskatchewan,
Canada. Axiom Exploration Group Ltd. of Saskatoon, Saskatchewan, has mobilized a gravity
geophysical crew to the Property to survey selected target areas along the Cable Bay Shear Zone
(the “CBSZ”), a major structural feature that bisects the Property.
Highlights of the 2026 Gravity Survey
• Well-known basement-hosted and unconformity-type uranium deposits in the
Athabasca Basin region commonly exhibit a gravity low signature – an indicator of
potential clay-altered zones associated with uranium mineralization due to
hydrothermal alteration reducing the host rock density. Examples of significant uranium
mineralization within density-low anomalies include NexGen Energy’s Arrow deposit and
Paladin Energy’s Triple R deposit in the southwestern Athabasca Basin.
• Greenridge is carrying out a high-resolution ground gravity survey at the Property during
the final weeks of frozen ground conditions to cover target zones A1, A2 and A5, which
were identified by previous geophysics and drilling (Please see Figure 1).
• The helicopter-assisted survey operations will generate a low environmental impact
during station measurements, providing a sustainable exploration practice.
Russell Starr, Chief Executive Officer of the Company, commented, “The 2026 gravity survey is
designed to provide detailed geophysical data over what we consider to be priority uranium
target areas at Carpenter Lake. We believe the addition of high-resolution gravity data to our
database will greatly add to the definition of follow-up drilling to our inaugural 2025 drilling
program.”
About Carpenter Lake and the Cable Bay Shear Zone
Carpenter Lake is comprised of twelve (12) mineral claims covering approximately 18,680
hectares that straddle the southern margin of the Athabasca Basin Supergroup sandstones and
cover more than fifteen (15) kilometers of the CBSZ – a prominent crustal-scale geological
structure trending northeast-southwest that is largely underexplored for uranium deposits
(Please see Figure 1). The CBSZ is characterized by a well-defined conductive signature,
radiometric anomalies, and numerous historically mapped uranium occurrences.
Greenridge believes Carpenter Lake is highly prospective for the discovery of shallow, high-
grade basement-hosted uranium mineralization akin to the Rabbit Lake, Arrow, and Triple R
uranium deposits. The structural style and setting along the CBSZ are ideal for the existence of
a potentially significant mineralizing system, and the presence of conductive graphitic

metasedimentary rocks often associated with uranium deposition in the Athabasca Basin has
been confirmed by both historical drilling and the Company’s 2025 drilling on the Property.

Carpenter Lake is owned 60% by Greenridge and 40% by Renegade Gold Inc., with Greenridge
acting as operator of exploration activities. Greenridge can earn a 100% interest in the Property
by fulfilling a schedule of cash payments, common share issuances and exploration
expenditures (for details please see Greenridge’s news release dated May 30, 2024).
Community Engagement at Carpenter Lake
In 2024, Greenridge executed exploration agreements with the English River First Nation
(“ERFN”) and Kineepik Metis Local #9 (“KML”), each of whom have ancestral rights within the
Property area, to provide members of each community with a role in environmental monitoring,
cultural management, and financial benefits from business, employment, and training
opportunities. Greenridge is dedicated to carrying out its exploration at Carpenter Lake within
a mutually respectful and cooperative relationship with both the ERFN and KML.
Statement of Qualified Person
The scientific and technical information contained in this news release has been reviewed and
approved by Sean Hillacre, P. Geo., a geological consultant to the Company and a Qualified
Person as defined in National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
Mr. Hillacre has examined information regarding historical exploration at the Property, which
includes a review of the analytical results of the 2025 drilling program.
The 2026 gravity survey will employ a Scintrex CG6 Autograve instrument to collect sub-surface
readings within a virtual grid established by a Trimble R12i GNSS global positioning system
receiver. Ground penetrating radar will be used to map ice thickness, and to profile lake bottoms
for better interpretation of the data collected on frozen lakes.
Management cautions that historical results collected and reported by operators unrelated to
Greenridge have not been verified nor confirmed by its Qualified Person; however, the historical
results create a scientific basis for ongoing work at the Property. Management further cautions
that published historical results and discoveries on adjacent or nearby mineral properties are
not necessarily indicative of the results that may be achieved on the Property.

CSE: GXP | OTC: GXPLF | FRA: HW3
• The Black Lake Uranium Project, located in the NE Athabasca Basin, (40% Greenridge,
50.43% Uranium Energy Corp., 8.57% Orano Canada) saw a 2004 discovery hole (BL-18)
