Antler Gold Announces Option Agreement

with Prospect Resources Limited to Sell 51%

Interest of Its Highly Prospective Kesya Rare

Earth Project in Zambia

Halifax, Nova Scotia--(Newsfile Corp. - May 12, 2023) - Antler Gold Inc. (TSXV: ANTL) ("

Antler" or the

"Company

") is pleased to announce that Antler and its subsidiary Antler Exploration Zambia Limited

("

Antler Exploration

") have entered into an option agreement (the "

Option Agreement

") with Prospect

Resources Limited (ASX: PSC) (FSE: 5E8) ("

Prospect" or the "Partner

") pursuant to which Prospect

has an option to acquire 51% interest in Antler Exploration, which holds the Kesya Rare Earth Project

("

Project

") located in southern Zambia.

Deal Highlights:

Prospect has up to two years to acquire a 51% interest in Antler Exploration which holds

the Kesya Rare Earth Project via a total combined counterparty consideration and project

expenditure payments amounting to US$3.05 million.

Phase 1 commitment by Prospect is two cash payments of an aggregate of US$150,000

and US$350,000 in exploration expenditures as well as an issuance of US$500,000 worth

of Prospect common shares within 30 days of the completion of Phase 1.

Phase 2 option commitment by Prospect is a cash payment of US$150,000 and

US$750,000 in exploration expenditures as well as an issuance of US$500,000 worth of

Prospect common shares within 30 days of electing to proceed to Phase 2.

The final phase commitment by Prospect is a cash payment of US$150,000 as well as an

issuance of US$500,000 worth of Prospect common shares at the end of the 2 year

option period which will then earn Prospect 51% of Antler Exploration.

Project Highlights:

The Project covers a Large-Scale Exploration License Application where geological

mapping and surface sampling conducted by Antler Exploration has identified a large,

rare earth-element enriched carbonatite.

Rock chip samples assayed by Antler Exploration outline very encouraging total rare

earth element oxide (TREO) mineralisation contained within monazite and bastnaesite

with low levels of uranium and thorium.

The Kesya rock chip results provide highly anomalous surface values in rare earth

elements with the highest grab sample to date assaying 6559 ppm (0.66%) TREO.

The grab samples are enriched in neodymium (Nd) and praseodymium (Pr) oxides which

average 29% of the TREO content and makes this a very encouraging basket distribution.

Keysa's large amount of carbonatite outcrop allows for easy drill targeting offering

prospectivity to rapidly delineate a mineral resource and make a significant new rare

earth element discovery in Zambia.

Antler Exploration along with its partner Prospect are preparing for an initial 1,500m

diamond drilling program to test the subsurface expression and depth extent of the

mapped and sampled rare earth element enriched carbonatite.

Christopher Drysdale, CEO of Antler commented:

"We are extremely excited to announce this agreement with Prospect. It's a testament to our

commitment to strategic partnerships with highly credible organizations that share our vision for value

creation. Prospect has an outstanding track record, which is demonstrated by their successful

advancement of the Arcadia lithium project in Zimbabwe. This agreement represents a significant

milestone for Antler Gold as it underscores our ability to identify promising mineral prospects across

Africa and align ourselves with top-tier companies. Not only does this partnership enable us to

leverage Prospect's industry-leading expertise, but it also establishes a solid foundation for potential

future collaborations, while maintaining significant exposure to the highly promising Kesya REE

project."

Prospect's Managing Director and CEO, Sam Hosack, commented:

"The Option Agreement we have struck in relation to the highly prospective Kesya REE Project in

Zambia is another significant milestone, which extends our reach further into the battery and

electrification mineral sector in Africa, in line with our strategic objectives. Kesya has all the

ingredients of a world-class, rare earth enriched, carbonatite-hosted system, having also returned

significant values of the high-value REEs, neodymium and praseodymium, over a broad surface area

of the Project. Zambia is a leading jurisdiction to explore and develop mining operations in

subSaharan Africa, having a long-standing history in the resources sector, particularly for copper. This

includes excellent infrastructure and strong support from both the government and community, with

major companies like Barrick Gold and First Quantum Minerals already calling it home. We are

delighted to have reached this agreement with Antler, which is an established and respected

Canadian exploration and development company focussed on its flagship Erongo and Onkoshi Gold

Projects, located in central Namibia. The Kesya REE Project offers excellent potential to deliver a

significant new, highvalue rare earths discovery, with defined existing drilling targets and a well-

established operating environment. Subject to the satisfaction of all relevant conditions precedent,

this is a high-quality greenfield exploration play for Prospect."

Introduction and deal terms:

The Kesya carbonatite was first identified in 1961 by Bailey in the Kafue district in southern Zambia. An

initial mapping campaign by Antler demonstrated that it is enriched with rare earth elements and

warrants further exploration and drilling.

The Option Agreement is among Prospect, Antler and a subsidiary of Antler, Antler Exploration. Subject

to satisfaction of certain conditions precedent, Prospect will have the right to earn a 51% interest in

Antler Exploration over a two-phased earn-in arrangement over two years for total consideration of

US$3.05 million, which includes consideration payments to Antler and in-ground project expenditure.

Prospect will pay an initial non-refundable cash payment to Antler of US$50,000 on signing. Following

satisfaction of the conditions precedent under Phase 1, Prospect will pay Antler a further US$100,000 in

cash, and commit to spend US$350,000 on the Project within one year (subject to certain extensions

permitted under the Option Agreement). Prospect will also issue to Antler US$500,000 worth of

Prospect common shares at the completion of Phase 1 (the value of the common shares will be set at

the price of Prospect shares at the time of signing, based on previous 10-day VWAP).

After completion of Phase 1, Prospect can elect to proceed to Phase 2 or terminate the Option

Agreement (and in this case Prospect will hold no interest in Antler Exploration).

If Prospect proceeds to Phase 2, it is required to pay Antler a further US$150,000 in cash and issue

US$500,000 worth of Prospect common shares (the value of the common shares will be set at the price

of Prospect shares as at the time of election to proceed to Phase 2, based on previous 10-day VWAP),

and it will have the right, but not the obligation, to spend a further US$750,000 on the Project within one

year from completion of Phase 1 (subject to certain extensions permitted under the Option Agreement).

If Phase 2 is completed, Prospect will be entitled to exercise a call option to acquire 51% of the issued

and outstanding shares of Antler Exploration. To exercise the option, Prospect must make a final

payment to Antler of US$150,000 cash and issue US$500,000 worth of Prospect common shares (the

value of the common shares will be set at the price of Prospect shares as at the time of the exercise of

the call option, based on previous 10-day VWAP).

Prospect will consult with Antler in relation to the work program and budget but will ultimately determine

and manage all exploration activities in relation to the Project.

Upon completion of the acquisition, Antler Exploration will be governed by a shareholders agreement

("

Shareholders Agreement"

) among its shareholders. Prospect and Antler Exploration have agreed

on the key terms of the Shareholder Agreement, with a full form Shareholder Agreement to be entered

into in due course. Development funds for the Project are to be contributed by shareholders of Antler

Exploration on a pro-rata basis. If a party does not contribute its pro rata share, its shareholding will be

diluted via a prescribed formula. Neither party can be diluted below a 15% interest, from which point

such interest shall be free-carried through to the completion of a JORC-Code reportable or NI 43-101

compliant Feasibility Study. The shareholder can then elect to convert its free carried interest to a 2%

NSR or equivalent ("

Royalty

") and the other shareholder has a right but not the obligation to purchase

one half of the Royalty for US$5,000,000.

Proposed Exploration Programme

There has been no historic drilling done on the Kesya carbonatite and the subsurface beneath the extent

of the mapped carbonatite complex and the depth extension is yet to be tested. Antler along with

Prospect is designing a preliminary 1,500 metre diamond drilling programme at the project. (Figure.1)

The aim is to evaluate the continuity of the identified surface REE mineralisation to depth. The initial

exploration plan will be to drill twenty (20) 75m deep holes along the carbonatite as well as its contacts

with the country rock by using a heli-man portable drill rig and pending all environmental and statutory

approvals.

The Kesya REE Project, comprises a single, large-scale exploration license (LEL) application covering

1053.13 hectares and is located near the town of Kafue in southern Zambia in the Kafue Gorge. This

license is located approximately 90 km via a tarred road traveling south of the capital city of Lusaka and

has water and power infrastructure nearby. Once the LEL is granted, Antler's wholly owned Zambian

subsidiary, Antler Exploration Zambia Limited will own 95% of the Kesya REE Project. The remaining

5% of the Project has local ownership.

Project Geology

The Kesya Carbonatite intruded into gneisses of the Paleoproterozoic Basement Complex rock

sequences near the intersection of the mid-Zambezi-Luangwa Rift Valley and the Kesya Rift.

The Kesya Carbonatite is divided into two major rock types: Firstly, a coarse-grained carbonatite with

scattered country rock xenoliths: This carbonatite is mostly composed of coarse sövite with small

amounts of chlorite. The second rock type is a carbonatite breccia, which surrounds the main intrusion.

The major minerals identified are magnetite, quartz, apatite, Fe-rich phlogopite, monazite, thorite, Ti-

oxides, Fe-sulphides, calcite, ilmenite, and the REE-bearing mineral bastnaesite. Dating of apatite in

samples from the carbonatite indicate that it is of Neoproterozoic age (Kesya is ca. 535±16 Ma).

The carbonatite forms a central topographic high surrounded by deeply incised valleys along its margins

where weathering processes are more intense.

Field investigations by Antler, and petrological (Scanning Electron Microscope (SEM)) studies

completed during 2021 demonstrated that the rare earth mineralisation at Kesya is hosted mainly in

monazite (a REE phosphate mineral) and bastnaesite (a REE fluoro-carbonate mineral).

Rare Earth Element Mineralisation

Antler Gold has completed mapping and sampling campaigns at Kesya in 2021, which involved

reconnaissance work across the carbonatite complex and the collection of 51 rock chip grab samples

taken on the license.

Figure 6; below shows a small selection of these rock chip grab samples along with their sample ID's

O6530 (A), O6537 (B), O6514 (C) and O6551 (D).

The rock chip samples collected by Antler at Kesya proved to be strongly and consistently mineralised

with REE, with an average of 1280 ppm (0.13%) Total Rare Earth Oxide (TREO) content, peaking at

6559 ppm (0.66%) TREO.

Encouragingly, these samples also show consistently high contents of neodymium- and praseodymium

oxide - key primary materials in the manufacture of strong permanent magnets for powerful motors, used

in such devices as large, wind turbines, increasingly utilised in the global renewable energy sector.

Neodymium and praseodymium oxides average 29% of the Total Rare Earth Oxide (TREO) content of

the rock chip samples collected from Kesya (Figure 5).
