DENVER, CO / ACCESS Newswire / May 22, 2025 / Vox Royalty Corp. (TSX:VOXR)(NASDAQ: VOXR) ("Vox" or the "Company"), a returns focused mining royalty company, is pleased to share a significant exploration and development update for the Red Hill gold project in Western Australia ("Red Hill") from its royalty operating partner, Northern Star Resources Limited ("Northern Star"), released on May 15, 2025. Vox holds a 4.0% gross revenue royalty over mining lease M27/57 at Red Hill.

The Red Hill gold deposit is located 3.5km east of Northern Star's Kanowna Belle mine and processing plant and 22km north-east of Northern Star's Kalgoorlie Consolidated Gold Mines Operations ("KCGM"), which includes the Fimiston processing plant in Western Australia. KCGM and the Fimiston plant are currently undergoing a major brownfield expansion project ⁽²⁾ by Northern Star. The A$1.5 billion KCGM Mill Expansion Project is scheduled for commissioning in FY27 and expected to increase processing capacity from 13Mtpa to 27Mtpa. The Red Hill project was historically mined as an open pit operation between 2001 and 2007, producing approximately 467,000oz.

Spencer Cole, Chief Investment Officer stated: "This resource upgrade for the consolidated Kalgoorlie Operations, Fimiston mill expansion progress and permitting guidance from Northern Star reinforces Vox management confidence on the near-term Red Hill development pathway. We are encouraged that all required environmental studies and statutory government approvals are ongoing with a Mining Proposal and Mine Closure Plan expected to be submitted ahead of operations recommencing. With Northern Star planning to process Red Hill ore through its significantly expanded Fimiston mill-targeting 23Mtpa capacity in FY2027-Red Hill is clearly emerging as a priority satellite bulk-tonnage feed source within its Kalgoorlie Operations. The low-risk nature of the mineral resource, existing haul road access to Fimiston, and positive preliminary economic studies highlight why Northern Star are prioritizing this exciting gold deposit."

Significant Resource Estimate Upgrade ⁽¹⁾
On May 15, 2025, Northern Star announced the following:

• Recent drilling at Red Hill has focused on upgrading the Inferred Mineral Resources to an Indicated classification to support Ore Reserve growth.

• For the Kalgoorlie Operations, an increase in total ounces of 1.02Moz @ 1.4g/t Au Measured and Indicated (47Koz @ 1.9g/t Au Measured, 969Koz @ 1.4g/t Au Indicated) and 567Koz @ 1.5g/t Au Inferred, or 21%, in Mineral Resources and 0.3Moz @ 3g/t Au, or 19%, in Mineral Reserves (Probable), which included the following:

  • Maiden mineral resources and ore reserves at the Hercules deposit of 491Koz @ 2.1g/t Au Indicated, 425Koz @ 2.2g/t Au Inferred and 0.25Moz @ 3.1g/t Au (Probable), respectively (not royalty-linked); and

  • Resource growth of 525Koz @ 1.1g/t Au Measured and Indicated (47Koz @ 1.9g/t Au Measured, 478Koz @ 1.1g/t Au Indicated) and 142Koz @ 0.8g/t Au Inferred from multiple regional deposits (excluding Hercules) at the Kalgoorlie Operations, including the Red Hill royalty-linked deposit.

• Mineral Resources were estimated at a gold price of A$3,000/oz and Ore Reserves estimated at a gold price of A$2,250/oz.

In the same announcement, the following commentary and detailed mining assumptions were included in Appendix C, Table 1:

• Reporting of Exploration Results and Estimation of Mineral Resources:

  • "A previous iteration of the Red Hill Mineral Resource estimate was also sent for external peer review and risk analysis. This review found no fatal flaws and considered both the geological interpretation and Mineral Resource estimate to be low risk."

  • "Further drilling will continue to test the current resource area for bulk potential below the Red Hill pit during FY2025."

  • " The (resource) wireframe continues to an RL [Relative Level] of -350 m for targeting purposes. Mineral Resources are not reported below the -150 m RL due to lack of data below this depth "

• Estimation and reporting of Ore Reserves:

  • "A gold price of A$2,250 per ounce has been used in the optimisation of the Red Hill Project."

  • "The Ore Reserve Estimation is based on detailed life of mine pit design and reflects positive economic outcomes."

  • "A minimum Pre-Feasibility level study is completed prior to converting an ore zone into ore Reserve."

  • "The selected mining method for the Red Hill deposit is a bench mining open pit method, mined using conventional open pit mining methods (drill, blast, load and haul) utilising 250t class excavators and 180t trucks."

  • "Ore from the project will be processed through the Fimiston Processing Plant at the KCGM operation, hence no processing infrastructure is required."

  • "Agreements are in place and are current with all key stakeholders including traditional landowner claimants."

  • "All required Environmental Studies and Statutory Government approvals including works approvals and clearing permit are ongoing. A Mining Proposal and Mine Closure Plan will be submitted at later stage in appropriate manner for the operation to recommence."

KCGM Mill Expansion Progress
On April 29, 2025, Northern Star announced the following update on the KCGM Mill Expansion Project in its Quarterly Activities Report:

• The KCGM Mill Expansion Project, centred on the Fimiston Processing Plant, is expected to replace 85% of the 13Mtpa plant, increase overall processing capacity to 27Mtpa and consolidate the Gidji facility. KCGM is expected to operate at ~900koz per annum from FY29 (steady state), following a two-year ramp-up (FY27-28) upon completion of the Mill Expansion.

• KCGM Mill Expansion tracking to plan; transitioned from concreting into structural and mechanical installation.

• FY25 KCGM Mill Expansion CAPEX remains unchanged at A$500-A$530 million.

• Forecast free cash flow combined with cash on hand at Northern Star fully funds the Mill Expansion's A$1.5 billion capital expenditure budget.

• The overall project progress timeline and expected throughput increase from 13Mtpa to 23Mtpa in FY27 (1-July-2026 to 30-June-2027) is shown below in Figure 2:

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.
