Carolina Rush Announces Refiling Of Maiden Mineral Resource Technical Report For Brewer Gold-Copper Project

(MENAFN- Newsfile Corp) 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the current CIM Estimation of Mineral Resource and Mineral Reserves Best Practice Guidelines (2019) instead of the outdated 2003 version.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.

Table 1: Amended Brewer in Situ Mineral Resource Statement (0.4 g/t Au cutoff)

		Average Value	Material Content
I&I	Mass	Au	Cu	Au	Cu
	thousand tonnes	g/t	ppm	thousand oz	thousand lbs.
Indicated	6,167	0.97	1,266	192	16,671
Inferred	8,828	0.74	425	210	8,279
Differences may occur in totals due to rounding.

(1) 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.

(5) A NI 43-101 Technical Report supporting the Maiden Mineral Resource Estimate is filed on SEDAR+ at . Investors are encouraged to review the full report, which will provide further details on key assumptions, parameters, and risks associated with the Mineral Resource Estimate.

(1) 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.

(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.

(5) 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.

(6) A NI 43-101 Technical Report supporting the Maiden Mineral Resource Estimate is filed on SEDAR+ at . Investors are encouraged to review the full report, which will provide further details on key assumptions, parameters, and risks associated with the Mineral Resource Estimate.
