Vox Royalty Acquires Cash-Flowing Kanmantoo Copper-Gold Royalty in South Australia

DENVER, CO / ACCESS Newswire / May 15, 2025 / Vox Royalty Corp. (TSX:VOXR)(NASDAQ: VOXR) (" Vox " or the " Company "), a returns focused mining royalty company, is pleased to announce today that it has completed the acquisition of an immediately cash-flowing royalty over the producing Kanmantoo copper-gold mine in South Australia (the " Kanmantoo Royalty "), from a private company, for total cash consideration of $11.7 million. The transaction is fully financed by an initial drawdown of $11.7 million from Vox's credit facility with Bank of Montreal. The Kanmantoo mine is a producing underground mine operated by ASX-listed, Hillgrove Resources Limited (" Hillgrove "), centrally located 55km from the city of Adelaide. The Kanmantoo Royalty is a 2.5% NSR payable monthly, stepping down to 0.50% NSR after reaching cumulative production of 85,000t copper (approximately 72,435t remaining as at 30 April 2025). All amounts in U.S. dollars unless otherwise indicated.

Kyle Floyd, Chief Executive Officer stated: "We are pleased to announce this accretive acquisition of the cash-flowing Kanmantoo Royalty in South Australia, operated by the experienced management team at Hillgrove. Based on Hillgrove's production forecasts for 2025, the Kanmantoo 2.5% royalty is expected to generate over $3 million of annualized royalty revenue ⁽³⁾ . In addition to the growing production profile at Kanmantoo, we see significant optionality from the ~60% latent capacity in the existing 3.6Mtpa processing plant, which has potential to be unlocked through the 60,000m drilling program in 2025 and the significant 25Mt - 40Mt regional exploration target. We believe the Kanmantoo asset provides our investors with exceptional exposure to a royalty that has both strong current production and growth potential in terms of mine life and mill utilization. This royalty fits well within our strongly weighted portfolio to Australia as one of the top ranked mining jurisdictions."

Transaction Highlights

• Fully operational underground copper-gold mine in South Australia that is expected to produce 12,000t - 14,000t copper in 2025 with meaningful gold and silver byproduct credits;

• The Kanmantoo underground mine is located 55km from Adelaide and successfully operated as a series of open pits from 2010 to 2020, producing around 137,000t of copper and over 55,000 oz of gold. Mining from the underground operation commenced in May 2023, with commercial production declared in July 2024;

• Extensive established infrastructure in place following initial capital investment of A$200 million between 2010 and 2020, with significant expansion potential with 3.6Mtpa processing plant currently ~40% utilized;

• Provides Vox shareholders with immediate copper revenue exposure and further strengthens Vox's industry-leading proportionate weighting of royalty assets to Australia;

• Current total resource as at September 30, 2024 comprises 8.8Mt @ 0.81% Cu, 0.13g/t Au Measured & Indicated and 10.1Mt @ 0.73% Cu, 0.14g/t Au Inferred ⁽¹⁾

• Significant exploration upside potential, as demonstrated by the Kanmantoo Region JORC-2012 Exploration Target ⁽¹⁾ of 25Mt - 40Mt @ 0.7% - 1.4% Cu and 0.05 - 0.5g/t Au as of February 13, 2025;

• 60,000m drilling program for 2025 well underway, which is expected to yield an updated mineral reserves and resource estimate later in 2025, potentially supportive of a mine life extension;

• Contractors currently at site to commence an accelerated development of the gold-dominant Nugent deposit underground decline, as part of the company's production growth strategy for 2025, with first ore from Nugent expected in Q4-2025. Underground grade control drilling at Nugent returned the following results ⁽⁴⁾ :

  • 18.55m @ 5.69% Cu + 1.02g/t Au (uncut) from 187m downhole (hole 24KVUG0476); and

  • 16.00m @ 2.96% Cu + 0.42g/t Au (uncut) from 197m downhole (hole 24KVUG0503)

Kanmantoo - Asset Overview

The Kanmantoo mine is located in South Australia, 55 km southeast from the city of Adelaide, and is operated by ASX-listed Hillgrove Resources. The mine has a rich history originally dating back to 1846. From 2010 to 2020, open pit mining at Kanmantoo yielded approximately 137kt Cu and 55koz Au. During this period, Hillgrove invested approximately A$200 million into the project, including the construction of a 3.6Mtpa processing plant.

In April 2022, Hillgrove commenced underground development and operations, declaring first underground copper concentrate production and commercial production in Q1 and Q2 2024, respectively. The transition to an underground operation marked a significant shift in the mine's operational strategy, with an intended focus on deeper, higher-grade orebodies previously inaccessible via the open pits.

Hillgrove is currently mining the Kavanagh zone and has stated plans to delineate and access deeper and higher-grade Nugent ore in the near term. On April 24, 2025, Hillgrove announced that contractors had been mobilized to start the underground decline at Nugent as part of its Stage 1 production expansion strategy, with first ore scheduled for Q4-2025 to enable a 25% increase in production and a decrease operating unit rates ⁽⁵⁾ .

Various exploration targets have been identified, including but not limited to Emily Star, North Kavanagh, Matthew, Valentines, Paringa, Critchley and Coopers. On April 22, 2025, Hillgrove announced that it had identified new mineralisation at the Valentine zone, below the Valentine Open Pit, approximately 180m below previously mined areas, and 300m away from existing underground infrastructure, confirming the potential for new copper mineralization within the existing mining lease. A third diamond drill rig has also been mobilized, expected to accelerate exploration and resource expansion at Kanmantoo, as part of Hillgrove's 60,000m drilling program.

The latest mineral resources statement is as follows (as at September 30, 2024) ⁽¹⁾ :

The mineral reserves statement is as follows (as at September 30, 2024) ⁽¹⁾ :

Hillgrove achieved its highest-ever quarterly copper production in Q1 2025, reporting 2,952t Cu produced, representing a 12% increase over the prior quarter and a new benchmark since starting underground operations in 2024. The record output was achieved due to improvements in copper grades and metallurgical recoveries. A total of 338kt were mined in the quarter, while 1,817m of development were completed, reflecting positive operational momentum building at site. Hillgrove also re-affirmed its production guidance of 12,000 - 14,000t copper for 2025, indicating confidence in continued strong performance.

Hillgrove's JORC-2012 exploration target (February 13, 2025) ⁽¹⁾ is distributed across the following lodes as follows:

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 ").

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.
