Vancouver, British Columbia--(Newsfile Corp. - March 22, 2022) - World Copper Ltd. (TSXV: WCU) (OTCQB: WCUFF) ("World Copper" or the "Company") announces that further to its news release dated February 15, 2022, it has filed on SEDAR a National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") technical report with respect to the preliminary economic assessment ("PEA") for its Escalones copper project in Chile ("Escalones").

The technical report is entitled "Preliminary Economic Assessment NI 43-101 Technical Report, Escalones Copper Project, Santiago Metropolitan Region, Chile" and is dated March 22, 2022, with an effective date of February 15, 2022 (the "Technical Report"). The Technical Report was prepared by Global Resource Engineering, with contributions from other firms, including Hard Rock Consulting, LLC. The Technical Report is available on World Copper's SEDAR profile at www.sedar.com and on World Copper's website at www.worldcopperltd.com.

Highlights of the PEA

• $1,499.6 million post-tax NPV8 at $3.60 /lb. life-of-mine ("LOM") (20-years) copper price
• $1,822.4 million post-tax NPV8 at US$4.00 /lb. LOM copper price
• First 5-years average annual Copper production of 124.7 Mlbs. (56,520 tonnes); LOM average 114.9 Mlbs. (52,131 tonnes)
• First 5-years average C1 (Cash Operating) costs of $1.13 /lb. Cu; LOM average C1 costs $1.19 /lb. Cu
• First 5-years average annual EBITDA $290.8 million; LOM average annual EBITDA $265.1 million
• Initial Capital (CAPEX) cost of $438.4 million (from construction decision)
• LOM Sustaining Capital of $192.5 million
• Conventional heap leach, SX-EW processing facilities, targeting 50,000 tonnes of heap leach tonnes placed per day

The exceptional results of the Escalones PEA confirm what World Copper has always anticipated - that Escalones has the potential to be one of the most impressive copper properties in South America. Escalones now joins a peer group of large-scale, study-backed, development stage assets. Escalones has several attributes that make it attractive for development including robust economics, strong value metrics and the potential of rapid returns for a comparably low capital investment. The results of the PEA, combined with Escalones' large land package and resource expansion potential, make it a truly outstanding project.

The PEA is considered preliminary in nature, contains numerous assumptions and includes Inferred Mineral Resources that are considered too speculative, geologically, to have the economic considerations applied that would enable them to be categorized as Mineral Reserves. There is no certainty that the results of the PEA will be realized. No Mineral Reserves have been estimated for Escalones. Mineral Resources are not Mineral Reserves and 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. Mineral Resources are captured within an optimized pit shell and meet the test of reasonable prospects for economic extraction. All values are reported in US dollars unless otherwise noted.

ABOUT WORLD COPPER LTD.

World Copper Ltd., headquartered in Vancouver, BC, is a Canadian resource company focused on the exploration and development of its copper porphyry projects: Escalones and Cristal in Chile, and Zonia in Arizona. Two of these projects have estimated resources with significant soluble copper mineralization, and each has additional copper porphyry targets with exciting potential to expand the resource base.

About Escalones

The Escalones porphyry-skarn copper-gold project has estimated inferred resources of 426 million tonnes of 0.367% total copper within the oxidized zone, based on nearly 25,000m of drill core from 53 holes. The 3.45 billion pounds of copper should be amenable to heap leaching with an average recovery of 71%. The Company is focused on exploring the Mancha Amarilla target immediately to the south of the existing resource. In addition, three significant hydrothermal alteration zones, each measuring between 2,000 m and 3,000 m in diameter, lie 8-10 km to the north of the main discovery.

Mineral resources are not mineral reserves and do not have demonstrated economic viability as there is no certainty that all or any part of the resources will be converted into reserves. Inferred resources are that part of a mineral resource for which quantity and grade or quality are estimated based on limited geological evidence and sampling. It is reasonably expected that the inferred resources could be upgraded to indicated resources with continued exploration.

About Zonia

The Zonia project is in Yavapai County, Arizona, and consists of 261 mineral claims and additional surface rights, all totaling 4,279.55 acres. It is a near-surface, copper-oxide resource and a brownfields site having already been mined in the late 1960s and '70s. The Project is at the PEA level and has been significantly de-risked with over 50,000 m of drilling completed to date and with substantial amounts of detailed engineering completed. Further details can be found here.

The World Copper team has a unique skill in navigating the mining sector within Chile, with some members having worked in the country for more than 40 years and with discovery success.

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 Definition Standards on Mineral Resources and Mineral Reserves, adopted by the Canadian Institute of Mining, Metallurgy and Petroleum Council on May 19, 2014, as amended ("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.
