World Copper Announces Grade-Confirmation Programme at the Zonia Copper Project, Arizona

World Copper Ltd. (TSXV: WCU) (OTCQB: WCUFF) (FSE: 7LY0) ("World Copper" or the "Company"; announces a grade-confirmation programme at its Zonia copper-oxide project in Arizona, USA ("Zonia" or the "Zonia Project").

As a past producer, Zonia hosts over 7.1 million tons (containing up to 55 million pounds of copper) of run-of-mine mineralized material placed on three leach pads in the 1970's. This material is not currently considered in the project's Mineral Resource Estimate. This partially processed material is located on private patented land and is easily accessible (see the release from July 2^nd, 2024, for further details). It presents a significant opportunity to add value to the project and could potentially become an additional early revenue source, having a positive effect on Zonia's future economics and NPV (net present value).

Historical documents (a mine production report from 1979 and a project evaluation report from 1982) estimated remnant copper content of the pads ranging from 26.6 million lbs to 55 million lbs, with a grades ranging from 0.4% to 0.6% Cu. Therefore, the Company has initiated a grade-confirmation programme, which will include surface studies, drilling, and metallurgical testing to confirm the acid-soluble copper grade of this material. The programme will involve up to 1,100 metres (3,600 feet) of reverse circulation ("RC") drilling, followed by metallurgical testing and additional in-fill drilling, if required.

Re-processing historical material often presents very attractive economics. At Zonia, this material is readily available and could be processed at lower cost than the bedrock resource. Following the completion of the grade-confirmation programme and securing the necessary permits, the Company plans to focus on designing the most optimal solution for reprocessing the material either through a small, portable SX-EW plant or by crystallizing copper sulfate, a marketable product requiring less upfront investment. This production could occur prior to commencement of the full-scale production from Zonia's main mine plan, as outlined in the historical preliminary economic assessment ("PEA") of 2018.

Mr. Gord Neal, CEO of World Copper, states: "Confirmation of existing copper metal sitting on our leach pads is a real opportunity to generate pre-production revenue, The grade-confirmation programme is a crucial first step towards creating additional shareholder value through potential upfront cash flow."

Readers are cautioned that the above historical quantities and grades reported in the historical reports have not been verified by the Company and there has been insufficient work to determine if the numbers in the historical reports are accurate. The potential quantity and grade of copper at the historical heap leach pads are conceptual in nature, as there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource. The Company is not treating the opportunity target as current mineral resources or mineral reserves.

ABOUT THE ZONIA PROJECT

Zonia is in the Walnut Grove Mining District, Yavapai County, Arizona, and consists of 96 patented and 185 unpatented mineral claims, 566.85 acres of surface rights acquired from the State of Arizona, and 376 acres purchased from a private estate, all totaling 4,373 acres.

Zonia is a near-surface, copper-oxide resource and a brownfields site having already been pre-stripped and mined in the late 1960s and '70s. The project has been significantly de-risked with over 50,000 metres of drilling completed to date and with substantial amounts of detailed engineering completed. The PEA based on the Historical Resource Estimate indicated that the project could be advanced utilizing low-cost open pit mining and heap leach with SX-EW processing to produce pure copper cathode (a copy of the PEA technical report is available on Zonia Holdings Corp.'s (formerly Cardero Resource Corp.) SEDAR+ profile at www.sedarplus.ca).

In addition to the established resource, the Zonia land position contains a copper-molybdenum geochemical anomaly Zonia North located within the same prospective geology. This anomaly is located two kilometres northeast of the resource and represents a high-priority copper-oxide porphyry exploration drill target. For further details on the Zonia North target please refer to news releases from May 2, 2022.

The Zonia Project's most recent mineral resource estimate includes 75.7 million short tons grading 0.30% total-copper (Indicated Resources) containing 450.5 million pounds of copper and 122.0 million short tons grading 0.24% total-copper (Inferred Resources) containing 575.4 million pounds of copper (see news release dated February 23, 2023).

The Updated Resource Estimate was completed by Richard A. Schwering P.G., SME-RM, of Hard Rock Consulting, LLC of Lakewood, Colorado ("HRC"), an independent qualified person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"), for World Copper as part of the Company's overall exploration plan for Zonia (see news release dated May 22, 2022).

Table 1. Resource Estimate for Zonia

Notes:

1. The effective date of the Updated Resource Estimate is September 1, 2022.
2. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred Mineral Resources are that part of the mineral resource for which quantity and grade or quality are estimated on the basis of limited geologic evidence and sampling, which is sufficient to imply but not verify grade or quality continuity. Inferred Mineral Resources may not be converted to mineral reserves. It is reasonably expected, though not guaranteed, that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration (see "Cautionary Note to United States Investors").
3. Mineral resources are reported using a variable total-copper cut-off. The cut-off grade for blocks was calculated based on the following assumptions: a long-term copper price of US$3.60/lb., assumed combined operating ore costs of US$6.25/ton (low grade re-handle, process, and general and administrative costs), refining & shipping costs of US$0.15/lb. of copper, and copper metallurgical recoveries of 73% for blocks coded as oxide and 70% for blocks coded as transition.
4. Mineral resources are captured within an optimized pit shell and meet the test of reasonable prospects for economic extraction by open pit. The optimization used the same mining costs of US$4.75/Ton mined and a 50º pit slope.
5. Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.

Cautionary Note to United States Investors

World Copper prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Terms relating to mineral resources in this news release are defined in accordance with NI 43-101 under the guidelines set out in CIM Standards. The U.S. Securities and Exchange Commission (the "SEC") has adopted amendments effective February 25, 2019 (the "SEC Modernization Rules") to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934.

As a result of the adoption of the SEC Modernization Rules, the SEC will now recognize estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", which are defined in substantially similar terms to the corresponding CIM Standards. In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be substantially similar to the corresponding CIM Standards.

U.S. investors are cautioned that while the foregoing terms are "substantially similar" to corresponding definitions under the CIM Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Standards. Accordingly, there is no assurance any mineral resources that World Copper may report as "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had World Copper prepared the resource estimates under the standards adopted under the SEC Modernization Rules.

In accordance with Canadian securities laws, estimates of "inferred mineral resources" cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43‑101.
