Homerun Resources: Establishing a Vertically Integrated Leader in

Troy Minerals Inc. (“Troy” or the “Company”) (CSE:TROY)(OTCQB:TROYF)(FSE:VJ3) is pleased to provide notice that a National Instrument 43-101 technical report (“NI 43101” or “Technical Report”) on the maiden Inferred Mineral Resource Estimate (“MRE” announced on June 30, 2025) for high-purity silica at its 100%-owned Table Mountain Project (“Table Mountain” or the “Project”), located (Figure 1) near Golden, British Columbia, has now been filed.

The Technical Report, “NI 43-101 TECHNICAL REPORT ON THE TABLE MOUNTAIN PROJECT, Golden Mining Division, British Columbia, Canada” has an Effective Date of June 30, 2025 and is available on SEDAR+ and on corporate web site www.troyminerals.com.

Key Highlights (as announced on June 30, 2025 and presented in the Technical Report):

• 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.

Yannis Tsitos, President of Troy, said “We are delighted to file the Technical Report in support of the previously disclosed maiden MRE for our Table Mountain high-purity silica project in BC, which marks another significant step for the Company. The size and quality of the Inferred geological resources, as well as the excellent local infrastructure with the Trans-Canada highway crossing the Project and the main railway being only 4 km away provide the foundation for our management to look after our next exploration and development steps for Table Mountain.”

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.

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.
