Vox Royalty Enters into Binding Agreement to Acquire Australian Copper and Gold Royalty Portfolio

DENVER, CO / ACCESS Newswire / August 20, 2026 / Vox Royalty Corp. (NASDAQ:VOXR)(TSX:VOXR) (“Vox” or the “Company“), a returns-focused mining royalty and streaming company, is pleased to announce that its wholly owned subsidiary, Vox Royalty Australia Pty Ltd (“Vox Australia“), has entered into a binding Royalty Sale and Purchase Agreement (the “Agreement“) with Latitude 66 Limited (“Lat66“) and its wholly owned subsidiary, Syndicated Royalties Pty Ltd, for the acquisition of two Australian royalty interests, (i) the Kalman Royalty in Queensland, and (ii) the Sylvania Royalty in Western Australia, for total cash consideration of up to A$3.4 million. The transaction remains subject to the completion of conditions precedent customary for a royalty transaction of this nature.

Spencer Cole, President and Chief Investment Officer, stated: “The Kalman and Sylvania Royalties are textbook Vox assets – Australian copper & gold royalties, with prospective regional geology, ongoing catalysts and proximity to existing processing plants. The Kalman project hosts a substantial copper-gold mineral resource and offers a potential pathway to fast-tracked development, as a long-term ore feed source for Hammer Metals proposed acquirer, Austral Resources’, Rocklands processing facility. Sylvania adds further exposure across a substantial 1,700km² land package. Both acquisitions continue to build our exposure to the Tier 1 mining jurisdiction of Australia, which is subject to the completion of customary conditions precedent.”

Kalman Royalty

The Kalman Royalty is a 2.0% royalty on production from Queensland tenement EPM13870 operated by ASX-listed, Hammer Metals (subject to August-2026 ongoing takeover with Austral Resources (“Austral“)), inclusive of applicable renewals, extensions, conversions and substituted tenure. The tenement hosts the majority² of the Kalman copper-molybdenum-gold-rhenium deposit, which includes conceptual open pit potential to 300 metres depth within JORC Indicated Cu-Mo-Au-Re sulphide mineral resources, together with further underground mining potential within JORC Inferred mineral resources at depth (see Figure 1). Tenement EPM13870 includes the Kalman deposit, Kalman West prospect and Hammertime prospect.

The Kalman deposit hosts a significant copper-gold-molybdenum-rhenium mineral resource, as summarised in Table 1 below:

Kalman project operator, Hammer Metals, has attracted a series of corporate acquisition offers over the course of 2026. Larvotto Resources made the first approach on June 10^th, 2026, followed by an unsolicited proposal from Austral on July 6^th, 2026. Austral then returned with a superior proposal on August 2^nd, 2026, which culminated in an executed Scheme Implementation Deed (“Hammer-Austral Scheme“) on August 11^th, 2026. In its August 11, 2026 ASX announcement, Hammer Metals identified the strategic fit between the two companies’ operations as a core rationale for the deal: Hammer’s Kalman copper-gold project sits roughly 60km by road from Austral’s Rocklands processing facility, positioning it as a potential long-term source of sulphide ore feed once Austral restarts the 3.0Mtpa plant in mid-2027. The Hammer-Austral Scheme is currently expected to be implemented in November 2026.

Sylvania Royalty

The Sylvania Royalty comprises a 1.0% Net Smelter Return (“NSR“) royalty on precious minerals and a 1.5% NSR royalty on all other minerals, payable under the Royalty Deed between Greenmount Resources Pty Ltd (“Greenmount“) and Lat66, over approximately 1,700km² tenure in Western Australia. Completion of the Sylvania Royalty acquisition is conditional upon Greenmount waiving its existing right of first refusal (“ROFR“) in respect of the royalty, or the ROFR period expiring without acceptance.

Consideration and Conditions Precedent

The total cash consideration payable under the Agreement is upto A$3.4 million, to be paid with cash on hand, upon completion of the respective royalty acquisitions. Completion of the Kalman Royalty and Sylvania Royalty acquisitions is independent of each other, with the Agreement providing for standard completion processes for each. The transaction remains subject to completion of conditions precedent customary for a royalty transaction of this nature, and, subject to satisfaction or waiver of the applicable conditions precedent, completion of each royalty acquisition is expected to occur within five business days thereafter.

Cautionary Statements to U.S. Securityholders

This press release and the documents incorporated by reference herein, as applicable, have been prepared in accordance with Canadian standards for the reporting of mineral resource and mineral reserve estimates, which differ from the previous and current standards of the U.S. securities laws. In particular, and without limiting the generality of the foregoing, the terms “mineral reserve”, “proven mineral reserve”, “probable mineral reserve”, “inferred mineral resources,”, “indicated mineral resources,” “measured mineral resources” and “mineral resources” used or referenced herein and the documents incorporated by reference herein, as applicable, are Canadian mineral disclosure terms as defined in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM“) – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Definition Standards“). In addition to NI 43-101, a number of resource and reserve estimates have been prepared in accordance with the JORC Code (as such term is defined in NI 43-101), which differ from the requirements of NI 43-101 and U.S. securities laws but is defined in NI 43-101 as an “acceptable foreign code”. Readers are cautioned that a qualified person has not carried out independent work to validate the JORC Code resource and reserve estimates referenced herein.

For U.S. reporting purposes, the U.S. Securities and Exchange Commission (the “SEC“) has adopted amendments to its disclosure rules (the “SEC Modernization Rules“) to modernize the mining property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934, as amended, which became effective February 25, 2019. The SEC Modernization Rules more closely align the SEC’s disclosure requirements and policies for mining properties with current industry and global regulatory practices and standards, including NI 43-101, and replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7. Issuers were required to comply with the SEC Modernization Rules in their first fiscal year beginning on or after January 1, 2021. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system, the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Definition Standards. Accordingly, mineral reserve and mineral resource information contained or incorporated by reference herein may not be comparable to similar information disclosed by companies domiciled in the U.S. subject to U.S. federal securities laws and the rules and regulations thereunder.

As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources.” In addition, the SEC has amended its definitions of “proven mineral reserves” and “probable mineral reserves” to be “substantially similar” to the corresponding CIM Definition Standards that are required under NI 43-101. While the SEC will now recognize “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”, U.S. investors should not assume that all or any part of the mineralization in these categories will be converted into a higher category of mineral resources or into mineral reserves without further work and analysis. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that all or any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable without further work and analysis. Further, “inferred mineral resources” have a greater amount of uncertainty and as to whether they can be mined legally or economically. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred mineral resources will be upgraded to a higher category without further work and analysis. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms are “substantially similar” to CIM Definitions, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules or under the prior standards of SEC Industry Guide 7.
