Resource Estimates Technical Reports (NI 43-101)

Carolina Rush Announces Refiling of Maiden

Mineral Resource Technical Report for Brewer

Gold-Copper Project

Toronto, Ontario--(Newsfile Corp. - August 8, 2025) - Carolina Rush Corporation (TSXV: RUSH)

(OTCQB: PUCCF) ("Carolina Rush," "Rush" or the "Company") announced that, as a result of a review

by staff of the Ontario Securities Commission ("OSC"), the Company has amended and refiled its

Technical Report titled "NI 43-101 Technical Report on the Brewer Gold -Copper Project, South

Carolina", originally filed on May 2, 2025.

The OSC review was conducted as part of its continuous disclosure review program specifically related

to the requirements under National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI

43-101").

The Company has addressed the following items in the amended Technical Report:

Authorship and independence:

Patrick Quigley, the Company's Senior Geologist and

Exploration Manager, was removed as a co-author of the report to comply with NI 43-101

requirements for independent authors. Patrick Hollenbeck, an independent Qualified Person,

assumes sole authorship and responsibility.

Updated CIM Guidelines:

The amended report reflects the current CIM Estimation of Mineral

Resource and Mineral Reserves Best Practice Guidelines (2019) instead of the outdated 2003

version.

Metallurgical Recovery:

A responsible metallurgical recovery assumption, based on historical

Hazen test work (1984), was applied to support the cut-off grade used in the mineral resource

estimate.

Constraining surfaces for RPEEE:

To demonstrate reasonable prospects for eventual

economic extraction (RPEEE), the Company constrained the mineral resource within a conceptual

open-pit shell.

Clarification on High-Grade Assay Handling:

Additional disclosure was provided on the use of

"high-yield limits" to constrain the influence of statistical outliers.

Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability.

(2)

The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or

other relevant issues.

(3)

The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must

not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an

Indicated Mineral Resource with continued exploration.

(4)

The Mineral Resources in this report were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on

Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the

CIM Council.

encouraged to review the full report, which will provide further details on key assumptions, parameters, and risks associated with the Mineral

Resource Estimate.

Details on the metallurgical properties and processing methods required to extract gold and copper from the backfill material have not been

undertaken.

As such, the Backfill resource is considered theoretical and additional studies are required to report the inferred resources at a

higher level of confidence.
