Highlander drills 23.9 m of 20.82 g/t Au at San Luis

Mr. Daniel Earle reports HIGHLANDER SILVER REPORTS RECORD RESULTS AND NEW DISCOVERY: 23.9M AT 20.82 G/T GOLD AND 31.53 G/T SILVER AND 23.4M AT 11.70 G/T GOLD AND 26.10 G/T SILVER IN SHALLOW DRILLING Highlander Silver Corp. has released exceptional assay results from shallow drilling at its expanding Bonita vein system. These results include the highest grades reported to date and the discovery of a new zone in stepout drilling over 200 metres northwest of prior holes along trend. The Bonita vein system is exposed along a ridgeline approximately 10 kilometres to the south of the bonanza-grade Ayelen deposit at the San Luis gold-silver project in central Peru. Highlights are listed below, with detailed results in the table. Highlights: BOD-025 returned 27.0 metres of 5.28 grams per tonne gold and 52.97 g/t silver from near surface at 2.3 m downhole, marking the discovery of the Urpicha zone over 200 m northwest of the nearest hole in BOD-003 (14.5 m of 3.70 g/t Au and 17.47 g/t Ag from 25.7-metre depth –- see press release dated July 29, 2025). The Urpicha discovery confirms the potential of the Bonita vein system to host strong mineralization near surface to the northwest of prior drilling where multiple parallel structures remain to be tested and the zone remains open along strike. BOD-023 tested the Kusy zone and intersected one of the broadest continuous intervals of near-surface high-grade mineralization reported to date, with 23.9 m of 20.82 g/t Au and 31.53 g/t Ag returned from 21.0 m downhole, in a hole oriented to the south of previously reported BOD-021 (23.6 m of 15.56 g/t Au and 74.49 g/t Ag from 8.8-metre depth –- see press release dated Oct. 6, 2025); BOD-022, also testing the Kusy zone, returned 23.4 m of 11.70 g/t Au and 26.10 g/t Ag from 13.5 m downhole from a platform to the southeast of BOD-019 (7.4 m of 8.10 g/t Au and 6.55 g/t Ag from 48.4-metre depth -- see press release dated Oct. 6, 2025); The company is incorporating the results of phase 1, including the assay results of the drilling to date, processing and analyzing the drone-based geophysical survey to identify permissive structural features across more than 5,000 hectares encompassing the outcropping Bonita vein system and its potential extensions, and integrating the latest drilling, mapping, soil and channel sampling results to design the optimal drilling campaign for phase 2. Preliminary results have revealed several zones exhibiting structural patterns and geophysical signatures analogous to those hosting mineralization tested by recent drilling, with newly identified targets to the west under cover, to the east and along strike. Complete analysis is expected to be available in the new year. Note: Portion of high-grade interval displaying silicified breccia and veinlets in andesite. Technical information and quality control/quality assurance All drilling was completed with HQ core. The drill core is split in half using a diamond saw. Core is logged by the company's geologist on site who outlines the intervals to be sampled. The maximum sample length is 1.5 metres, and lengths are adjusted according to lithological and/or mineralogical contacts. After sawing, one-half of the core is kept on site in core boxes, and the other half is submitted for analysis. Individual sample bags are sealed and placed into larger bags, which are then sealed and marked with the contents. Samples are transported by Highlander Silver personnel to ALS Peru SA located in Lima, Peru, where they are prepared and analyzed. ALS is independent of the company. In ALS, the entire sample is crushed to approximately 80 per cent passing through a two-millimetre sieve. A 500-gram fraction is pulverized. Gold concentration is determined by fire assay of a 30-gram charge with an AA finish (Au-AA23). Silver, lead, copper and zinc, along with other elements, are analyzed by ICP utilizing a four-acid digestion (ME-ICP61). Overlimit samples for Au (10 g/t Au) follow gravitational finishing Au-GRA21 (30-gram sample). Overlimit samples for Ag (100 g/t Ag) follow gravitational finishing Ag-GRA21 (30-gram sample). The internal quality assurance/quality control program includes the submission of field duplicates (one-fourth core), pulp and coarse reject duplicates, and the insertion of commercial standards and blanks (coarse and fine). Control samples account for more than 15 per cent of the total samples sent, in addition to the laboratory's internal quality assurance programs. The company is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein. The scientific and technical information, including the drill hole data, has been verified by Dr. Sergio Gelcich. This verification involves data validation and quality assurance procedures, such as reviewing logging directly in front of the core, analyzing database integrity, conducting quality assurance and quality control for assays, and cross-checking the original lab certificates.
