World Copper Identifies New Opportunity at Zonia Copper Project in Arizona

Vancouver, July 2, 2024 - World Copper Ltd. (TSXV: WCU) (OTCQB: WCUFF) (FSE: 7LY0) ("World Copper" or the "Company") provides an update on its Zonia copper-oxide project in Arizona, USA ("Zonia" or the Zonia Project").

A review of historical data by World Copper's newly formed Technical Advisory Committee has revealed the potential for re-processing mineralized material that was included in the historical mine plan at the Zonia Project. This material, located on heap leach pads from historical production on private patented land, and last processed in the mid-1970s, was treated with acid to recover soluble copper. Two historical reports, a 1979 mine production summary report by McAlester Fuel Company ("McAlester") and a 1982 resource evaluation report by Mountain States Research & Development ("MSRD"), indicate that the site hosts over 14 million tons of historically mined material available for re-processing:

• 7.1 million tons of run-of-mine mineralized material placed on three historical heap leach pads; and
• 7.7 million tons of blasted and leveled in-situ leach ("ISL") mineralized material.

For the material placed on the three heap-leach pads, the average original (pre-leaching) copper grade estimated by drilling prior to production was reported to be between 0.6% total copper ("CuT") (McAlester production report) and 0.4% CuT (MSRD report estimate based on drilling of the leach pads). This yielded 30.5 million pounds of copper during its operational period of March 1966 to March 1975, which means that between 26.7 and 55.1 million pounds of copper could remain unrecovered from the pads, based on the reported original grade of the mineralized material. McAlester further reported that between mid-1972 to March 1975, the ISL area produced 2.70 million pounds of copper from material with estimated original copper grades between 0.269% and 0.292% CuT (McAlester and MSRD respective estimates), indicating that this area could contain between 38.6 and 41.8 million pounds of copper. According to these two reports the total potential unrecovered material from both the three leach pads and the ISL area could range between 65 million pounds to 96 million pounds of copper. As a result, World Copper's Technical Advisory Committee believes the Company should investigate the possibility of re-processing the run-of-mine and ISL material for unrecovered copper.

Readers are cautioned that the above historical quantities and grades reported in the McAlester production report and MSRD report 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 and ISL area is conceptual in nature, 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.

Given that the heap leach pads are on private patented land, they are readily accessible from a permitting perspective. To confirm the quality of the mineralized material for re-processing, the Company expects to complete a confirmatory drilling programme and metallurgical testing on the leach pads to confirm the volume, grade, and mineralogical characteristics of the material and to estimate the potentially recoverable pounds of acid-soluble copper. If the grade and mineralogical characteristics of the historically mined material is confirmed through the results of the exploration program, the Company will also analyze if the mineralized material could be processed before any potential future mining of the bedrock resources.

Mr. Gord Neal, CEO of World Copper, commented: "The prospect of re-processing historically mined mineralized material would add more value and provide additional upside to the Zonia Project, and it is a unique potential value opportunity. In mining projects, any opportunity to start production early and to generate revenue right from the start of the operations, can greatly improve the economics of the project increasing the net present value (NPV) and reducing the financing needs, making the project more robust, and lowering the execution risk.".

World Copper remains committed to advancing the Zonia Project and maximizing shareholder value through innovative and strategic approaches to resource development.

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.
