Project
Toronto, Ontario--(Newsfile Corp. - April 28, 2025) - Carolina Rush Corporation (TSXV: RUSH)
(OTCQB: PUCCF) ("Carolina Rush," "Rush" or the "Company") is pleased to report initial results and
analysis from its recently completed magnetotelluric (MT) and induced polarization (IP) geophysical
surveys conducted at its Brewer Gold-Copper Project in South Carolina, USA. The survey has revealed
compelling subsurface features that suggest the presence of a buried porphyry system.
Highlights
A large columnar zone of low resistivity has been identified below and west of the former mine,
extending to depths greater than 1,500 meters.
A broad halo of high chargeability surrounds this zone, extending more than 500 meters deep.
Magnitudes and geometries of the low-resistivity and high-chargeability bodies are consistent with
an inferred intrusion and sulfide shell, and may represent the underlying porphyry source for
Brewer's high sulfidation Au-Cu mineralization.
The geophysical models, in conjunction with geological models, present compelling drill targets to
test for the presence of a buried Cu-Au porphyry system.
"We are extremely encouraged by these results, which confirm our long-standing belief in Brewer's
deeper porphyry potential," said Layton Croft, Carolina Rush President and CEO. "The clear data-driven
correlation between our geological model and geophysical signatures provides a powerful case for a
buried porphyry system. These are exactly the kind of high-quality deep drill targets we had hoped the
MT-IP survey would reveal. Now we are designing a drill program to determine the mineralization
potential of the Brewer porphyry target."
Survey Parameters and Design
The Brewer MT-IP survey was conducted by Zonge International Geophysical Services (Zonge) over a
four-week period beginning February 24, 2025. The survey consisted of 5 lines approximately 3.8 km in
length spaced 200 meters apart across the Brewer property (see Figure 1). The survey was designed to
cover the extent of advanced argillic alteration exposed on the surface, and to map the geology down to
depths of approximately 1,500 meters.
The tensor MT survey was conducted with 100-meter stations
along each line. The dipole-dipole IP survey was conducted with 400-meter transmitter dipoles and 100-
meter receiver dipoles, with 100-meter array moves up to N=32.5.

Discussion and Analysis
2D section models were generated from both the MT and IP data. These 2D models were gridded in 3D
volumes to facilitate multi-dimensional analyses as shown in Figure 2 above and Figure 3 below. The 3D
MT resistivity and IP chargeability volumes are instrumental in characterizing the inferred deep porphyry
system.
The MT-IP surveys were designed to test the concept that a deep porphyry Cu-Au system is the source
for Brewer's high sulfidation Au-Cu mineralization at and near surface (see Figure 4). Analyses of the 3D
MT resistivity volume confirm the presence of a low-resistivity columnar body extending from below the
former Brewer mine to depths > 1,500 meters, an excellent representation of a typical porphyry system
(Figure 4). The conceptual porphyry model shown in Figure 4, and the geophysical models and RAB
geochemistry shown in Figure 3, are in excellent agreement. The deep-sensing MT-IP survey has proven
successful at furthering the understanding of Brewer's porphyry Cu-Au potential.
The Brewer Exploration Team is now integrating all geological, geochemical, and geophysical datasets
to design a focused drill program aimed at testing the inferred porphyry system interpreted from the
recent MT-IP surveys.

Finally, as a follow up to its
February 18, 2025 news release
, the Company now confirms that it has
dropped its Sawyer and New Sawyer exploration projects in North Carolina. This is due to the priority of
focusing on exploring Brewer's deeper porphyry copper-gold potential.

About Carolina Rush
Carolina Rush Corporation (TSXV: RUSH/ OTCQB: PUCCF) is exploring the Carolina Terrane in the
southeastern USA. Its Brewer Gold-Copper Project is located at the past-producing, 397-hectare
Brewer Gold Mine property in Chesterfield County, South Carolina, 17 kilometers along trend from the
producing Haile Gold Mine (

).
The proximity of the Brewer Gold-Copper Project to the Haile Gold Mine does not imply that
mineralization or results from Haile are indicative of mineralization at Brewer.
