Star Metro - Troy Minerals Announces Maiden Inferred Resource Estimate for High-Purity Silica at Table Mountain Project, BC

Key Highlights:

• Inferred Mineral Resource of 56,945,602 tonnes Inferred at an average grade of 98.91% SiO₂, with very low levels of impurities. Overall analytical sampling results range from 95.82% to 99.82% SiO₂.

• The resource remains open along strike and at depth. Future exploration is expected to further expand the resource base and upgrade portions of the MRE to higher confidence categories.

This maiden MRE, prepared in accordance with NI 43-101 standards, consists of an Inferred Resource of 56,945,602 tonnes of quartzite grading an average of 98.91% SiO₂. The results establish Table Mountain as a significant high-purity silica deposit in British Columbia and mark a major milestone in Troy's development of this critical mineral asset. The resource is comprised of an extensive quartzite (silica) bed of the Ordovician Mount Wilson Formation and remains open for expansion along strike and at depth with further exploration.

"This maiden resource estimate at Table Mountain marks a major milestone for Troy Minerals," stated Yannis Tsitos, President of Troy Minerals. "We are extremely encouraged by the size and quality of this maiden high-purity silica resource, which validates the strategic value of the project. As global demand for high-purity silica continues to grow, establishing a solid resource base is a critical step toward developing Table Mountain into a future production center. We believe this achievement paves the way for the next phase of growth for Troy, and we will continue to advance the project aggressively to unlock its full potential."

Initial MRE Overview

The initial MRE (Table 1) was prepared by Ray GeoConsulting Corporation ("RGC") in accordance with the 2014 Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards and Canadian National Instrument 43-101 ("NI 43-101"). RGC is independent of Troy Minerals Inc.

The following is the current Mineral Resource Estimate as at June 27, 2025 (the "Effective Date").

Table 1. Mineral Resource Estimate (MRE) Summary

Notes:

1. CIM (2014) definitions were followed for Mineral Resources.

2. Bulk density within the quartzite unit is 2.766 t/m³.

3. No recovery, dilution, or other similar mining parameters have been applied. No cutoff grade has been applied.

4. Brian Ray, P.Geo. of RGC, an independent Qualified Person who prepared the initial MRE is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing, political, or other relevant factors that could materially affect the Mineral Resource estimate.

5. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and there is no certainty that the Company will be able to convert inferred mineral resources to higher confidence categories, however it is reasonably expected that the majority of the Inferred Mineral Resource could potentially be upgraded to an Indicated Mineral Resource with continued exploration.

6. A Technical Report is being prepared to support this resource estimate in accordance with National Instrument 43-101 ("NI 43-101"), and will be available on the Company's website and SEDAR within 45 days of the date of this news release.

Following the completion of this encouraging maiden resource, Troy Minerals is moving swiftly to advance the Table Mountain Project toward development. The Inferred Resource will be incorporated into a forthcoming NI 43-101 Technical Report, and the Company is outlining further work to maximize the project's value.

Next Steps

• NI 43-101 Technical Report: Troy is preparing a detailed Technical Report in accordance with NI 43-101 guidelines to support the new resource estimate. The report - including methodologies, data, and modeling parameters - will be filed on SEDAR within the required 45-day period, providing full disclosure of the resource modeling and assumptions.

• Phase II Exploration Program: Planning is underway for a follow-up sampling campaign as well as a drilling campaign aimed at expanding the resource and upgrading a portion of the Inferred resource to Measured and Indicated categories. The programs will test the continuity of high-grade silica mineralization beyond the currently established zones and at depth, where the deposit remains open.

• Metallurgical Testing & Economic Studies: The Company will initiate comprehensive metallurgical testing (including purity analyses and process trials on bulk samples) to confirm that the Table Mountain silica meets specifications for high-end industrial uses. Subsequent to metallurgical testing, Troy intents to initiate scoping, economic studies.

About the Table Mountain Project

The Table Mountain Silica Project is located approximately 4 kilometres east of Golden, B.C., Canada, with excellent year-round road access and proximity to the Canadian Pacific Railway's Golden rail yard (Figure 2). The property covers roughly 2,304 hectares, encompassing up to 10 kilometres of regionally mapped strike length of the Mount Wilson Formation quartzite, with widths ranging from 300 to 1,400 metres at surface. Table Mountain is strategically situated near two established high-purity silica operations - the Moberly Silica Mine and the Sinova Quartz Quarry - both of which demonstrate silica purity greater than 99.6% SiO₂. This advantageous location highlights the project's potential to become a significant source of high-purity silica in a region known for hosting premium-quality silica deposits.
