Carolina Rush Identifies Compelling Porphyry Drill Targets from Deep-Sensing MT-IP Geophysical Survey at Brewer Gold-Copper Project
Carolina Rush (TSXV: RUSH) (OTCQB: PUCCF) has announced significant findings from its magnetotelluric (MT) and induced polarization (IP) geophysical surveys at the Brewer Gold-Copper Project in South Carolina. The surveys, completed by Zonge International, revealed compelling evidence of a potential buried porphyry system.
Key findings include:
- A large columnar low-resistivity zone identified below and west of the former mine, extending beyond 1,500 meters depth
- A broad high-chargeability halo surrounding this zone, extending over 500 meters deep
- Geophysical signatures consistent with an inferred intrusion and sulfide shell
The survey, conducted over four weeks starting February 24, 2025, covered 5 lines approximately 3.8 km in length, spaced 200 meters apart. The company is now designing a focused drill program to test the identified targets. Additionally, Carolina Rush has announced the discontinuation of its Sawyer and New Sawyer exploration projects in North Carolina to focus on Brewer's porphyry copper-gold potential.
Carolina Rush (TSXV: RUSH) (OTCQB: PUCCF) ha annunciato risultati significativi dai suoi sondaggi geofisici magnetotellurici (MT) e di polarizzazione indotta (IP) presso il progetto Brewer Gold-Copper in South Carolina. Le indagini, realizzate da Zonge International, hanno rivelato prove convincenti di un possibile sistema porfirico sepolto.
Le principali scoperte includono:
- Una vasta zona a bassa resistività colonnare individuata sotto e a ovest della vecchia miniera, che si estende oltre i 1.500 metri di profondità
- Un ampio alone ad alta carica elettrica che circonda questa zona, estendendosi per oltre 500 metri in profondità
- Segnali geofisici coerenti con un'intrusione ipotizzata e una guscio di solfuri
Il sondaggio, condotto nell'arco di quattro settimane a partire dal 24 febbraio 2025, ha coperto 5 linee di circa 3,8 km di lunghezza, distanziate di 200 metri. L'azienda sta ora progettando un programma di perforazione mirato per testare gli obiettivi identificati. Inoltre, Carolina Rush ha annunciato la cessazione dei suoi progetti di esplorazione Sawyer e New Sawyer in North Carolina per concentrarsi sul potenziale porfirico di rame-oro di Brewer.

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.
