Mergers & Acquisitions

XAU RESOURCES INC. ANNOUNCES ENTRY INTO DEFINITIVE AGREEMENT TO

ACQUIRE QS HOLDINGS INC.

Toronto, Ontario – June 10, 2026

XAU Resources Inc. (TSXV: GIG) (“XAU” or the “Company”) is pleased to announce, further

to its prior news release on April 23, 2026, that it has entered into a definitive business

combination agreement dated June 10, 2026 (the “ Business Combination Agreement ”)

with QS Holdings Inc., a company incorporated under the laws of Barbados (“ QS

Holdings”), pursuant to which XAU will acquire all the issued and outstanding common

shares of QS Holdings (the “Acquisition”) by way of a three-cornered amalgamation under

the Companies Act of Barbados. The Acquisition will entail QS Holdings amalgamating with

a newly incorporated wholly owned subsidiary of XAU (“ Subco”), and the amalgamated

entity (“Amalco”) will become a wholly owned subsidiary of XAU. The shareholders of QS

Holdings will receive common shares of XAU (the “Consideration Shares”) in exchange for

their QS Holdings shares, based on an exchange ratio calculated using a deemed aggregate

purchase price of C$70,000,000 for the QS Holdings shares and a price of $0.50 per

common share of XAU, which was the “Market Price” (as defined under the policies of the

TSX Venture Exchange) of the common shares of XAU immediately preceding the execution

of the Business Combination Agreement.

Trading of the common shares of XAU has been halted and will remain halted pending

receipt and review by the TSXV of the requisite filings in respect of the proposed Acquisition.

The Acquisition is subject to the satisfaction of customary closing conditions, including

receipt of all required regulatory approvals, and is expected to close in the third quarter of

2026.

Completion of the Acquisition is subject to a number of conditions, including but not limited

to: (i) approval of the Acquisition by the shareholders of QS Holdings as required by the

Companies Act of Barbados ; (ii) approval of the Acquisition by the shareholders of XAU as

required under TSXV Policies and/or applicable securities laws; (iii) conditional approval by

the TSXV for the listing of the Consideration Shares; (iv) the completion of the Concurrent

Financing (as described below); (v) the completion and delivery of audited financial

statements of QS Holdings (as described below) ; (vi) the entering into o f investor rights

agreements with certain shareholders (as described below) ; (vii) the reconstitution of the

XAU board to six directors, which shall include the incumbent XAU directors and two

nominees of certain shareholders of QS Holdings (as described below) ; (viii) holders of not

more than 10% of the common shares of QS Holdings having exercised any applicable

dissent rights; (ix) there being no mate rial adverse effect in respect of either party; (x) the

satisfaction of any requirements pursuant to MI 61 -101; and (xi) other customary closing

conditions. The Outside Date for completing the Acquisition is October 31, 2026.

QS Holdings has a 100% interest in Qstone Inc., a private Guyanese company, which is the

registered owner of the mining permits known as the Quartzstone Gold Project which cover

296 km² across 83 contiguous medium -scale mining permits in Guyana. The Quartzstone

Gold Project is subject to an earn-in agreement with Fortuna Mining Corp. (“ Fortuna”)

pursuant to which Fortuna may earn up to a 70% interest in the Quartzstone Gold Project.

Fortuna may earn an initial 51% interest in the Quartzstone Gold Project by completing a

minimum of 60,000 metre s of drilling within four years, while paying all license fees and

funding all related expenditures. Upon exercise of the first option, Fortuna will form a joint

venture with Qstone. Fortuna may earn an additional 19% interest in the Quartzstone Gold

Project, for an aggregate 70% interest, by solely funding a feasibility study within three years

of exercising the first option and continuing to pay all license fees.

In addition to royalties payable to the Government of Guyana on gold production, the

Quartzstone Gold Project is subject to a 4.5% net smelter returns royalty in favour of a prior

owner, which may be repurchased at any time at a price to be determined by the parties.

Certain directors and officers of XAU also hold interests in QS Holdings. Peter Hambro and

Gary Bay are directors and officers of XAU and are also shareholders of QS Holdings. Gary

Bay is also a director of QS Holdings. Accordingly, the Acquisition does not constitute an

“Arm’s Length Transaction” under TSXV Policy and may constitute a "related party

transaction" or "business combination" under MI 61 -101. XAU’s special committee of

independent directors (the “Special Committee”), comprised of Nataliya Hearn (Chair) and

Danièle Spethmann, has overseen the negotiation of the Business Combination Agreement

and has received a fairness opinion from Evans & Evans, Inc. stating that, and based upon

and subject to the assumptions, limitations, and qualifications set forth therein, the

consideration offered pursuant to the Acquisition is fair, from a financial point of view, to the

Company’s shareholders.

Recommendation

The Special Committee, and the board of directors of XAU based on the unanimous

recommendation of the Special Committee, has determined that the Acquisition is fair, from

a financial point of view, to the shareholders of XAU and is in the best interests of XAU. The

XAU board of directors recommends that XAU shareholders vote in favour of the Acquisition

and the related transactions and matters contemplated in the Business Combination

Agreement. The parties will determine the applicability of specific MI 61 -101 and TSXV

requirements in connection with the Acquisition. The management and board of directors

of XAU are expected to remain the same both before and after giving effect to the

Acquisition, subject to the addition of Robert Jenkins and Rory Carleton Paget as nominees

of certain QS Holdings shareholders to the XAU board.

The Business Combination Agreement supersedes the non-binding letter of intent dated

March 26, 2026, as amended. The Business Combination Agreement contains customary

provisions governing the conduct of business pending closing, non-solicitation covenants,

rights to match competing proposals, expense reimbursement provisions, and other

customary terms and conditions. There can be no assurance that the Acquisition will be

completed as proposed or at all. Investors are cautioned that, except as disclosed in any

management information circular of XAU to be prepared in connection with the Acquisition,

any information released or received with respect to the Acquisition may not be accurate or

complete and should not be relied upon. Trading in the securities of XAU should be

considered highly speculat ive. The TSXV has in no way passed upon the merits of the

Acquisition and has not approved or disapproved of the contents of this news release.

Terms of the Acquisition

Pursuant to the Business Combination Agreement, XAU will acquire all of the issued and

outstanding common shares of QS Holdings (currently consisting of 100,000 common

shares) in consideration of the issuance of Consideration Shares based on an exchange

ratio calculated using a deemed aggregate purchase price of C$70,000,000 for the QS

Holdings shares. The value of Consideration Shares to be issued is based on a price of $0.50

per common share of XAU, which was the “Market Price” (as defined under the polic ies of

the TSX Venture Exchange) of the common shares of XAU immediately preceding the

execution of the Business Combination Agreement. The Acquisition will be structured as a

three-cornered amalgamation under the Companies Act of Barbados, whereby QS Holdings

will amalgamate with Subco, resulting in Amalco becoming a wholly owned subsidiary of

XAU. No cash consideration is payable as part of the Acquisition; the entire purchase price

is to be satisfied through the issuance of Consideration Shares. No fractional Consideration

Shares will be issued; any fractional entitlement will be rounded down to the next lesser

whole number of Consideration Shares without additional compensation.

No finder’s fee or commission has been paid or is payable in connection with the

Acquisition, other than any such fee or commission which may be agreed to in relation to

the Concurrent Financing (as described below).

The Business Combination Agreement includes customary representations, warranties,

covenants and conditions and certain other provisions including non-solicitation provisions

and other deal protection clauses, subject to the right of XAU to accept a superior proposal

in certain circumstances, with QS Holdings having a 5-business day right to match any such

superior proposal. The Business Combination Agreement also provides for each party to be

reimbursed (by the other) for its reasonable and necessary costs and expenses incurred in

connection with the Acquisition if the Business Combination Agreement is terminated by

the other party in certain circumstances. Such reimbursement will be limited to a maximum

of C$200,000 in certain circumstances.

Upon completion of the Acquisition , existing XAU shareholders will own between

approximately 47.7% (minimum Concurrent Financing) and 42.8% (maximum Concurrent

Financing) of XAU (which figures include the Consideration Shares to be received by Peter

Hambro and Gary Bay (together with his spouse Ksenia Povzner-Bay), who are shareholders

of both XAU and QS Holdings) , former QS Holdings shareholders (excluding Peter Hambro

and Gary Bay (together with his spouse Ksenia Povzner -Bay)) will own between

approximately 41.0% (minimum Concurrent Financing) and 36.8% (maximum Concurrent

Financing) of XAU, and investors in the Concurrent Financing will own between 11.3% and

20.3% of XAU Shares , in each case on an undiluted basis. XAU will have approximately

176,761,500 common shares issued and outstanding assuming the minimum Concurrent

Financing or approximately 196,761,500 common shares issued and outstanding assuming

the maximum Concurrent Financing . The Acquisition may be considered an “RTO” under

TSXV Policy. XAU will continue to be involved in the same industry sector, and XAU will

continue trading under the name XAU Resources Inc. and ticker symbol TSXV:GIG following

the closing of the Acquisition.

Location of Target Assets and Jurisdiction of Target Company

QS Holdings is incorporated under the laws of Barbados. QS Holdings is the sole beneficial

owner of all of the issued and outstanding share capital of Qstone Inc., which is

incorporated under the laws of the Co -operative Republic of Guyana, with its regist ered

office located at Lot 143A Robin’s Place West, Bel Air Park, Georgetown, Guyana. Qstone

Inc. holds the mineral rights in respect of the Quartzstone Gold Project, consisting of 83

contiguous medium-scale mining permits totalling 73,062 acres (approxima tely 296 km²)

located in the Cuyuni/Mazaruni Area, Region #7, Guyana. The mining permits are governed

by the Mining Act (Cap. 65:01) of Guyana and related legislation.

About the Quartzstone Gold Project

The Quartzstone Gold Project (the “ Property”) is an advanced-stage gold exploration

property located in the Cuyuni-Mazaruni Region of north-central Guyana, approximately 120

kilometres west of Georgetown and 45 kilometres east -southeast of Zijin Mining Group's

Aurora Gold Mine. The Property compris es 83 medium -scale mining permits covering

approximately 29,570 hectares, all in good standing with the Guyana Geology and Mines

Commission.

The Property lies within the Palaeoproterozoic Barama-Mazaruni Supergroup of the Guiana

Shield — one of the world's most prolific orogenic gold belts — and hosts gold mineralization

along a regional north -south shear zone spanning more than 25 kilometres along the

western flank of a Trans-Amazonian granite intrusive. The tectonic setting is comparable to

that for the Oko deposits (G Mining and G2 Goldfields) 22 kilomet res southeast of

Quartzstone, which occur along a north-south shear zone on the western flank of the Bartica

Gneissic complex. Refer to Figure 1.

Gold at Quartzstone occurs in quartz and quartz -tourmaline-carbonate veins and breccia

zones plus sericite -silica alteration zones hosted in the granite contact shear structure,

within north-northeasterly trending cross structures which cut across the western volcano-

sediments and into the granite on the east, and within quartz -veined brittle deformation

zones within the granite. Historical drilling by the prior owner included 183 diamond drill

holes totalling over 23,000 metres, with significant (un-cut) gold intersections including 10.5

metres at 19.9 g/t Au 1 (Main Pit zone), 12.0m at 10.8 g/t Au 2 (Main Pit zone) and 5.6 metr es

at 27.8 g/t Au 3 (Blue South zone). Drilling has tested less than 5 kilometr es of strike of the

25+ kilometre long granite contact structure. In addition, several trenches along the main

north-south structure returned exceptional (un -cut) gold intersections which have not yet

been drill-tested, including 21.5 metr es at 13.2 g/t Au 4, 7.1 met res at 21.9 g/t Au 5 and 17

metres at 4.5 g/t Au. Neither QS Holdings nor Qstone Inc. has conducted any exploration or

development work on the Property since its acquisition of the Property in 2025.

The Property hosts a historical Mineral Resource estimated to consist of 933,000 tonnes at

5.44 g/t Au for 163,200 ounces of gold Indicated plus 1,911,000 tonnes at 4.79 g/t Au for

294,500 ounces of gold Inferred 6. Further drilling and economic modelling is required to

1 Drill core samples (half core obtained with a diamond blade core saw) from the Main Pit prospect located at

251340E/735819N (UTM WGS84 Zone 21N). Drill hole oriented at 100° azim, - 60° dip. Intercept from 91.2m

down-hole and included 3.9m @ 52.1 g/t Au (uncut) from 91.2m. True width of the mineralization estimated to

be 95% of the core length.

2 Drill core samples from the Main Pit prospect located at 251243E/735868N. Drill hole oriented vertically.

Intercept from 242.7m down- hole and included 1m @ 101.6 g/t Au (uncut) from 246.7m. True width of the

mineralization estimated to be 60% of the core length.

3 Drill core samples from the Blue South prospect located at 251599E/736820N. Drill hole oriented vertically.

Intercept from 89.2m down- hole and included 2.5m @ 24.0 g/t Au (uncut) from 93.4m. True width of the

mineralization estimated to be 45% of the core length.

4 Trench intercept from the Camp Granite prospect centred at 251633E/735453N. 1-metre horizontal channel

samples obtained along close to the base of one wall, perpendicular to the strike of the geology and structure.

5 Trench intercept from the Mango Tree prospect centred at 251946E/737743N. 1 -metre horizontal channel

samples obtained along close to the base of one wall, perpendicular to the strike of the geology and structure.

Analysis of split drill core and trench samples was by 50g FA AAS finish, conducted at the independent Acme

Guyana Laboratory (later acquired by Bureau Veritas) in Georgetown, Guyana. QAQC consisted of sample

duplicates and pulp duplicates for a total of 1 0% of samples and was considered very good. Certified

Reference Standards and blanks were not introduced into the exploration programs until late, after these

samples were obtained. Review of the historical data, methodology and QAQC did not identify any c oncerns

that could materially affect the accuracy or reliability of the data.

6 Historical Mineral Resource Estimate (‘MRE’) prepared by Anton Kornitskiy presented in unpublished

Technical Report on the Quartzstone Project, Guyana, May 2020, authored by Jason Ché Osmond of Wardell

Armstrong, UK. The resource estimation was based on a sectional wireframe interpretation using a 0.40 g/t Au

cut-off. 64% of the total resource was classified as Inferred and 36% Indicated. Potentially open- pitable

resource material was constrained by $1,500 Au optimized pit shells with a 0.4 g/t Au cut -off. 65% of the total

resource fell below the conceptual pit shells and was classified as an underground resource for minimum

mining widths of 2.0 metres and using a cut -off grade of 1.5 g/t Au. The economic viability of the underground

resource was not validated by the 2020 resource estimation. The 2020 MRE included all of the known drilling

for the Quartzstone project and represents the most recent known resource estimation for the project. Further

(infill) drilling, an update of economic input parameters, remodelling and newly generated optimized pit shells

would be required to generate a current resource for the project. Using a higher gold price over the $1,500 used

in 2020 could deepen the conceptual pits and take in resource material that was considered underground

resource material in 2020. Mineralization falling below updated conceptual pits would need to be validated as

economically viable underground resources in order to be included in a current MRE update.

make the resource current. The historical Mineral Resource Estimate (“MRE”) is relevant for

understanding the general scale and style of mineralization; however, its reliability is limited

due to the use of estimation methodologies that do not meet current CIM Definition

Standards. Uncertainties exist in the historical MRE as the underlying data and estimation

methods have not been fully verified by the Company’s Qualified Person.

The mineralized zones remain open, and ongoing exploration has the potential to expand

the known mineralization in addition to making new discoveries on multiple, untested strike-

extensive structures, which could add to the resource at Quartzstone.

Figure 1. Location and Geological Setting of the Quartzstone Property

The qualified person has not done sufficient work to classify the historical estimate as

current mineral resources or mineral reserves. The issuer is not treating the historical

resource estimate as current mineral resources or mineral reserves.
