Highlander Silver Reports Results of Step-Out Drilling at Bonita: 24.8m at 7.43 g/t Au and 16.45 g/t Ag; 40.4m at 3.42 g/t Au and 16.93 g/t Ag
Highlander Silver Reports Results of Step-Out Drilling at Bonita:
24.8m at 7.43 g/t Au and 16.45 g/t Ag; 40.4m at 3.42 g/t Au and 16.93 g/t Ag
Toronto, Ontario, September 16, 2025 – Highlander Silver Corp. (TSX: HSLV; “Highlander
Silver” or the “ Company”) is pleased to report assay results from the second series of holes
designed to test the expanding Bonita vein system, which include some of the highest gold grades
encountered to date. The Bonita vein system is exposed along a ridgeline approximately 10km to
the south of the bonanza grade Ayelen underground deposit at the San Luis gold-silver project in
Central Peru.
Highlights are listed below, with corresponding images in Figures 1-2 and detailed results in
Tables 1-2.
Highlights
• The results of step -out drilling include some of the highest gold grades
encountered to date and extend mineralization to the southeast of prior drilling (see
press release ‘Highlander Silver Reports First Drill Results from Bonita Open Pit
Target, Including High Grades over Broad Widths from Near Surface in Every Hole’
– July 29, 2025)
• BOD-013 was drilled from a step-out platform to the southeast of prior drilling and
returned 24.8m of 7.43 grams per tonne (“g/t”) gold (“Au”) and 16.45 g/t silver (“Ag”)
from 28.7m downhole
• BOD-010 returned 40.4m of 3.42 g/t Au and 1 6.93 g/t Ag from surface to the
southeast of prior drilling from a platform at the edge of soils that may cover the
extent of the vein system to the west
• BOD-014 was drilled from a step -out platform to the southeast of BOD-010 and
returned 19.1m of 3.50 g/t Au and 11.57 g/t Ag from 37.7m downhole
• BOD-015, the southeastern most hole drilled to date, returned 23.7m of 3.31 g/t Au
and 9.60 g/t Ag from 34.3m downhole, with the zone remaining open in this direction
• The next set of drill results are expected to be released when complete assays are
received in approximately six weeks and will include step -out drilling from the
eastern known extent of the structure targeted by the initial drilling
• Bonita is located 10km to the south and 700m lower in elevation than Ayelen ; the
vein system encompasses a number of silicified stru ctures exposed in several
outcrops over an area of 800m by 200m and remains open in all directions
• A magnetic survey undertaken with two quadcopter drones has completed
approximately 5,000 hectares in the Bonita area, with the goal of mapping structural
features under cover to the west and in rugged topography to the east

Note: Reported intervals are apparent widths as the full geometry of the mineralized structures has not yet been fully
modelled. Assays were not capped, and composite intervals are calculated using a minimum weighted average of 0.5
g/t Au, diluted over a minimum core length that allows for internal dilution.

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. C ore
is logged by the Company’s geologist on site who outlines the intervals to be sampled . The
maximum sample length is 1.5 meters 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 S.A. (“ALS”) 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% passing through a 2mm sieve. A 500
g 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). Over-limit samples for Au ( 10 g/t Au) follow
gravitational finishing Au -GRA21 (30g sample) . Over-limit samples for Ag (100 g/t Ag) follow
gravitational finishing Ag-GRA21 (30g sample).
The internal QA/QC program includes the submission of field duplicates (1/4 core), pulp and
coarse reject duplicates, and the insertion of commercial standards and blanks (coarse and fine).
Control samples account for more than 15% 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 drillhole 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 (QA/QC) for assays, and cross-checking the original lab certificates.
