World Copper Announces Results from Mancha Amarilla Drilling, Confirms

Extension of Mineralization at Escalones Project in Chile

FOR IMMEDIATE RELEASE...Vancouver, British Columbia: World Copper Ltd. ( "World Copper") -

(TSX.V: WCU, OTCQC: WCUFF, FRA: 7LY0) announces drill results from the Mancha Amarilla target

at the Company's Escalones Copper project in Central Chile ("Escalones" or the "Escalones Project"). The

Escalones Project has estimated Inferred Mineral Resources of 426 million tonnes of 0.367% copper, based

on nearly 25,000 metres of drill core from 53 holes (see news release dated August 23, 2021). World Copper

has now completed 1,676 metres of additional drilling along the western-most, road accessible edge of the

Mancha Amarilla zone, with the following highlights:

• Successful completion of first target of Mancha Amarilla drilling, confi rming copper oxide

mineralization extends at least 150 metres south from previous drilling

• Oxidation extends to depths of 280 metres below the ridge, as predicted by modeling

• Confirmation of western flank of Mancha Amarilla mineralized zone with i ndications that

the mineralization should improve eastward into the central areas of the zone

CEO Nolan Peterson commented, "Since restarting work on the Escalones project, World Copper has

focused on completing the preliminary economic assessment with respect to the existing Escalones

resource, which was completed in February 2022 ( see news release dated February 15, 2022), as well as

expanding the Escalones' mineral resource south into the adjacent previously untested Mancha Amarilla

zone. With the completion of the first phase of the drill programme we have now confirmed what initial

reviews indicated - that the Escalones resource has the potential to be significantly larger than its current

definition, with oxide mineralization to similar depths as the main deposit. With the western edge of the

Mancha Amarilla footprint defined, we now have clear target s for the next phase of drilling, aiming to

increase the grade of the overall resource as we test the flanking s karn targets which exhibit some of the

highest grades on the property."

Mancha Amarilla Results

The aim of the Mancha Amarilla drill programme was to confirm and delineate continuous oxide copper

mineralization in the Mancha Amarilla lithocap, which is located adjacent to and located immediately south

of the existing mineral resource. Early drilling focused on the western edge and the East Skarn (Figure 1).

The Mancha Amarilla lithocap has alteration mineralogy and geochemistry consistent with the weathered

top of a porphyry system and extends one kilometre south from the area of the main Escalones deposit

(Figure 1). The geology encountered in the recent drilling indicates the Mancha Amarilla lithocap is as

deeply oxidized as the existing resource but thins southward as topography drops in elevation where

calcareous lithologies dominate over intrusive units. The increase in grade eastward from hole ES -57 to

ES-56 suggests the central area is more highly mineralized than t he western flank. The last hole of the

programme (ES-60) was collared in the East Skarn zone but was shut down early due to bad weather with

the onset of winter. Table 1 summarizes the significant drill intersections from the programme and Figure

1 shows their locations within the Mancha Amarilla zone.

Next Steps

With over 3,000 metres remaining in the Escalones drill permit, World Copper intends to restart drilling at

the East Skarn target (Figure 1) as soon as conditions allow. The East Skarn target overlies the Mancha

Amarilla zone to the northeast of the completed drilling and has only had sparse drilling along the south

edge (see news release dated August 12, 2021). Surface sampling by the Company indicates the sandstone

host rocks of the East Skarn target are strongly mineralized with copper oxides at surface. Once drilling at

the East Skarn target is complete, World Copper would aim to to move to the west side of the Meseta ridge

and test the depth potential of high-grade copper skarn mineralization exposed by roads on the west flank

of the central Meseta intrusion (the West Zone; Figure 1).

Quality Control and Quality Assurance; Sampling and Assay Procedures

Drill core was transported at the end of each drill shift by pickup truck from the drill pad to a temporary

logging, sampling and storage facility at the base camp at the south end of the ridge. The core was then

logged, digitally photographed, and transported to the core -storage warehouse in the town of Romeral ,

where the core was split with a diamond saw and sampled with half the core placed in plastic poly bags and

a sample tag. The core was photographed once again to record the sampling. After splitting, all samples

were packed in rice sacks and sealed with uniquely numbered non-re-sealable security straps. The samples

were trucked to ALS Laboratory ("ALS") in Santiago. World Copper implemented a standard QA/QC

programme for Escalones, inserting 1-in-20 certified standard reference material ( "SRM"), 1-in-20 field

(two ¼ core samples) and 1-in-20 coarse duplicates, and 1-in-25 blanks into the sample stream. There were

no issues noted with the SRMs and all plotted within acceptable limits for copper submitted for analysis

from the same sample interval.

At ALS, multi-elements were assayed using the ME-ICP61a package, which includes 4-acid digestion and

ICP-MS finish. Gold was done by method Au-ICP21, in which a 30g sample is fire -assayed and finished

with ICP-AES. Intervals of greater than 10 metres grading greater than 0.1% Cu will be sent for sequential

copper analysis.

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 25,000 m of drill core from 53 holes.

Preliminary metallurgy indicates 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 flanking skarn mineralization

east and west of the existing resource. In addition, three significant hydrothermal alteration zones, each

measuring between 2,000 m and 3,000m in diameter, lie 8- 10 km to the north of the main discovery. One

of these, Rio Negro, has confirmed porphyry mineralization at surface.

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 esti mated based on limited geological

evidence and sampling. It is reasonably expected that the inferred resources could be upgraded to indicated

resources with continued exploration.

• Conventional heap leach, SX -EW processing fa cilities, 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 classified 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 quan tity and grade, or quality, are estimated based on 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.

at www.sedar.com, 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

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 corres ponding 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 ter ms 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 Coppe r 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.
