Troy completes 2025 summer fieldwork at Table Mountain

Mr. Rana Vig reports TROY MINERALS REPORTS COMPLETION OF 2025 SUMMER FIELD PROGRAM AND PROGRESS AT TABLE MOUNTAIN HIGH-PURITY SILICA PROJECT, BRITISH COLUMBIA, CANADA Troy Minerals Inc. has completed its planned 2025 summer field exploration program and has provided a progress update at its 100-per-cent-owned high-purity silica Table Mountain project, located near Golden, B.C., Canada. For context, last month, Troy announced the filing of a National Instrument 43-101 technical report on the maiden mineral resource estimate of 56,945,602 tonnes inferred at an average grade of 98.91 per cent SiO2, with very low levels of impurities. The technical report's effective date is June 30, 2025, and it can be found on SEDAR+ and on the corporate website. Key highlights: Company expands the project by 222.2 hectares, covering the rest of Table Mountain; Additional channel sampling completed across the main quartzite silica zone; Extensive geological prospecting across the project, including across newly acquired claims to the north; Collection of two bulk quartzite samples totalling approximately 250 kilograms from the main quartzite silica zone for metallurgical studies; Completion of unmanned aerial vehicle lidar survey across 3.5 square kilometres across northern claims and the project's access areas. "The announcement of our maiden inferred resource earlier in the summer in conjunction with the successful completion of this season's exploration program represents an important step in the advancement of the Table Mountain silica project, an asset which benefits from its size, quality, infrastructure and location, situated across the Trans-Canada Highway and four kilometres away from the CPKC Golden rail yard," commented Yannis Tsitos, president of Troy Minerals. "With drill permits submitted for the 2026 season and our planned metallurgical works and scoping studies planned for the winter season, we are positioning Troy to move into the next stage of exploration and resource development at the Table Mountain project." Exploration program update Troy has expanded the project by 222.2 hectares through an amendment to the option agreement with the property vendor, making the total property holdings into 2,526.3 hectares. The additional ground was added directly to the north of the main silica zone, along strike of the Mount Wilson quartzite formation, adding potential for expanding the established zone to the north for approximately one kilometre. Troy recently completed a continuous channel sampling program within the main mineralized zone. This work was designed to provide a better understanding of grade continuity across the quartzite body and to generate the data required for precise drill hole planning in future campaigns. Prospecting crews conducted systematic exploration across the entire property, including the newly acquired northern claims. This program led to the discovery of several new quartzite exposures and potential high-purity silica targets, adding meaningful expansion potential to the existing project footprint. An unmanned-aerial-vehicle-borne lidar survey was flown across approximately 3.5 square kilometres on the expanded northern part of the property to aid in drill planning, as well as potential future resource estimates, plus covering areas important for project access from the Trans-Canada Highway. Two bulk samples, totalling approximately 250 kilograms, were collected from the main quartzite zone. These samples will undergo metallurgical testing to evaluate silica quality and identify impurities and potential suitability for high-end applications. Troy has submitted a drill permit application in anticipation of the 2026 field season. Once permits are approved, the company intends to complete resource definition drilling within the main zone, as well as initial testing of high-priority targets defined by the recent prospecting and channel sampling. The company will announce analytical results from the channel sampling and present the total lidar coverage maps to date, once processed and received. The company also announces that it has granted 1.5 million options to consultants and advisers of the company. The options have an exercise price of 12 cents, vest immediately and expire on Sept. 10, 2030. About the Table Mountain project The Table Mountain silica project is located approximately four kilometres east of Golden, B.C., Canada, with excellent year-round road access and proximity to the Canadian Pacific Railway's Golden rail yard. The property covers roughly 2,526 hectares, encompassing up to 11 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 per cent 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. Qualified person Technical information in this release has been reviewed and approved by Case Lewis, PGeo, a qualified person under National Instrument 43-101, a director of the property vendor.
