Notes to the Updated Resource Estimate Tables:

1. The effective date of the Updated Resource Estimate is August 27, 2024.

2. Resources are reported using the 2014 CIM Definition Standards and were estimated using the 2019 CIM Best Practices Guidelines, as required by NI43-101

3. The base case Mineral Resource has been confined by "reasonable prospects of eventual economic extraction" shape using the following assumptions:

1. Metal price of US$4.00/lb of Cu

2. Metallurgical recovery of 75% in oxides and 70% in the transitional zone

3. Offsite costs of US$0.05/lb of Cu

4. Processing Costs of US$4/ton milled and General & Administrative (G&A) costs of CDN$ 2.00/ton milled

5. Mining cost of CDN$2.00/ton mined

6. 48-degree pit slopes

7. The 150% price case pit shell is used for the resource confining shape

1. The resulting NSR = Cu*US$3.95/lb *0.75 for oxides and NSR = Cu*US$3.95/lb *0.70 in the transitional zone.

2. 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. Numbers may not add due to rounding.

4. There are no material differences between the mineral resources reported in the September 9, 2024 news release and the Technical Report.

Table 2. Zonia Mineral Resources Over a Range of Cut-off Grades

Mineral resources that are not mineral reserves do not have demonstrated economic viability; however, a reasonable prospect of eventual economic extraction pit has been used to confine the Updated Resource Estimate using parameters detailed in the table notes. The QP for the Updated Resource Estimate is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing, political, or other relevant factors that could materially affect the Updated Resource Estimate. Factors that may affect the estimate include: metal price assumptions, changes in interpretations of mineralization geometry and continuity of mineralization zones, changes to kriging assumptions, metallurgical recovery assumptions, operating cost assumptions, confidence in the modifying factors, including assumptions that surface rights to allow mining infrastructure to be constructed will be forthcoming, delays or other issues in reaching agreements with local or regulatory authorities and stakeholders, and changes in land tenure requirements or in permitting requirement.

Zonia Resource Modelling

Data verification efforts for the Updated Resource Estimate carried out by MMTS included discussions with World Copper personnel, personal inspection of the Project area with the collection and submission of check samples to an external laboratory, an audit of the exploration drillhole database, and a detailed review of additional information obtained from historical reports and information provided by the Company. MMTS also completed checks on the geologic information as compared to the paper logs, and checks of the assay values contained in the exploration database as compared to assay certificates provided by World Copper.

Cautionary Note Regarding Forward-Looking Statements

This news release contains forward-looking statements and forward-looking information (collectively, "forward-looking statements") within the meaning of applicable Canadian and U.S. securities legislation. All statements, other than statements of historical fact, included herein including, without limitation, statements with respect to anticipated exploration program results from exploration activities, and the discovery and delineation of mineral deposits/resources/reserves, are forward-looking statements. Although World Copper believes that such statements are reasonable, it can give no assurance that such expectations will prove to be correct. Forward-looking statements are typically identified by words such as: "believes", "expects", "anticipates", "intends", "estimates", "plans", "may", "should", "would", "will", "potential", "scheduled" or variations of such words and phrases and similar expressions, which, by their nature, refer to future events or results that may, could, would, might or will occur or be taken or achieved. In making the forward-looking statements in this news release, World Copper has applied several material assumptions, including without limitation, market fundamentals will result in sustained copper demand and prices, the receipt of any necessary permits, licences and regulatory approvals in connection with the future development of Zonia in a timely manner, the availability of financing on suitable terms for the development, construction and continued operation of World Copper's projects and its ability to comply with environmental, health and safety laws.

Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of World Copper to differ materially from any future results, performance or achievements expressed or implied by the forward-looking information. Such risks and other factors include, among others, operating and technical difficulties in connection with mineral exploration and development activities, actual results of exploration activities, including on Zonia, the estimation or realization of mineral reserves and mineral resources, the timing and amount of estimated future production, the costs of production, capital expenditures, the costs and timing of the development of new deposits, requirements for additional capital, future prices of copper, changes in general economic conditions, changes in the financial markets and in the demand and market price for commodities, lack of investor interest in future financings, accidents, labour disputes and other risks of the mining industry, delays in obtaining governmental approvals, permits or financing or in the completion of development or construction activities, risks relating to epidemics or pandemics, including the impact on World Copper's business, financial condition and results of operations, changes in laws, regulations and policies affecting mining operations, the inability of World Copper to obtain any necessary permits, consents, approvals or authorizations, the timing and possible outcome of any pending litigation, environmental issues and liabilities, and risks related to joint venture operations, and other risks and uncertainties disclosed in World Copper's continuous disclosure documents. All of World Copper's Canadian public disclosure filings may be accessed via www.sedarplus.ca and readers are urged to review these materials.

Readers are cautioned not to place undue reliance on forward-looking statements. World Copper does not undertake any obligation to update any of the forward-looking statements in this news release or incorporated by reference herein, except as otherwise required by law.

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.
