Daura Gold Reports High-Grade Results from
Antonella Infill Sampling of Historic Drill Core:
Upgrading Significant Intercepts, Including:
22.4m at 4.36 g/t Au & 23 g/t Ag from 36.8m
Vancouver, British Columbia--(Newsfile Corp. - February 23, 2026) -
Daura Gold Corp.
(TSXV: DGC)
(OTC Pink: DGCOF) ("Daura" or the "Company") is pleased to announce that, following a detailed
review of historical drill core, new high-grade infill sampling results have significantly enhanced the
precious metals intercepts at its flagship Antonella Project ("Antonella" or the "Project"), adjacent to
Highlander Silver Corp.'s Bonita Project in Ancash, Peru.
The previous, private owner of the Project
drilled 12 holes at Antonella in 2011 and selectively sampled drill core, leaving significant mineralized
intervals unsampled.
Systematic infill sampling of the historic core has increased gold equivalent

by 51%, confirming higher-grade continuity in the key vein
systems from existing core.
Highlights are listed below with corresponding images, drill map and sections in Figures 1-5.
Drill
intercepts are in Table 1.
Mark Sumner, CEO of Daura, commented,
"The systematic infill sampling of historic drill core has
significantly increased the previously reported gold and silver intervals at Antonella, revealing wide
intercepts across multiple holes and identifying high grade vein mineralization in 9 of 12 drill holes.
This new data underpins the potential of the Antonella project, as well as the quality of Daura's
technical team by recognizing and executing on the opportunity to enhance our drilling dataset."
Stuart Milles, VP of Exploration for Daura, commented,
"The upgraded drill intercepts at Antonella
provide critical new insights into Antonella's mineralizing system, including high-value pathfinder
geochemical vectors.
These data are essential for targeting high-grade extensions and expansion of
the Antonella deposit in the Company's future planned drill program."
Highlights of the Recent Drill Core Infill Sampling Program:
513 infill drill core samples were collected from the historic drill core from Antonella Main zone.

All drilling, sampling, analysis and reporting of historic core was reviewed and approved for release in
accordance with the policies of the TSX Venture Exchange by Owen D.W. Miller Ph.D. FAusIMM (CP),
an independent qualified person as defined by National Instrument 43-101 - Standards of Disclosure for
Mineral Projects ("NI 43-101").
Twelve diamond drill holes for a total of 2,461.25m of drill core were reviewed and re-logged by Daura.
Historic sampling of this drill core was not systematic and only 360m of drill core was previously sampled
for a total number of 314 samples taken.
Historic core was re-boxed with drill recovery, tag intervals and historic sampling checked by Daura's
staff. Re-logging of the core identified significant mineralization and alteration that had not been
previously sampled, and a program of systematic infill sampling yielded a combined additional 707.7m
of infill core for 513 samples.
The re-logging of historic drilling completed in 2011, in conjunction with systematic sampling of all
mineralized core that was not previously sampled has greatly increased Daura's understanding of the
Antonella vein system. This additional sampling has broadened the zones of mineralization considerably
with a cumulative increase in mineralized intervals in both gold and silver (see percentage upgrade of
significant historical intercepts in Table 1).
Gold Equivalent (AuEq.) grades have been calculated by the addition of gold grade plus silver grade
divided by 66 to reflect the nominal value of $4,900 / ounce gold and the nominal value of $74 / ounce
silver. This calculated AuEq. has been performed on reported intervals determined by the calculated
significant intersects, using gold only results with a 0.2 g/t gold trigger, a minimum 0.5 g/t gold composite
and a maximum of 3 meters consecutive waste.
The potential quantity and grade is conceptual in nature
as there has been insufficient exploration to define a mineral resource in this area and that it is uncertain
if further exploration will result in the target being delineated as a mineral resource.
Percent levels of base metals (Cu, Pb & Zn) are present within some of the logged mineralized zones
without appreciable gold and or silver. It is clear that multiple mineralizing events are present at Antonella
and that some events are base metal enriched without gold and or silver. The results for these low gold
zones are not reported in this news release.
Much of the newly identified mineralized zones recorded in the re-log contain geochemically anomalous
low-level gold and silver, together with associated pathfinder elements anomalous in copper, lead, zinc,
arsenic, antimony, tellurium, barium and manganese. These mineralized intervals with elevated
pathfinders correlate well with zones of veinlets, veins and breccias and will be used as exploration
vectors in the Company's future planned drill program.
Antonella is adjacent to Highlander Silver's Bonita Project in Peru's prolific Ancash metallogenic belt,
which hosts major deposits like Barrick's past-producing Pierina gold mine.
The Project's epithermal
vein system is hosted in Tertiary Calipuy Group volcanic rocks, controlled by NW-SE trending faults, with
silicification and argillic alteration halos up to 40m wide.

Significant Intercepts in this news release are calculated using a 0.2 g/t gold trigger, a minimum 0.5 g/t gold composite, a maximum of 3 meters
consecutive waste.
‡ Gold Equivalent is calculated by the addition of gold grade plus silver grade divided by 66 to reflect the nominal value of $4,900 / ounce gold and
the nominal value of $74 / ounce silver.
Next Steps
Daura will continue geological mapping and sampling across the Antonella concessions, when the
community's permission is obtained. Geophysical surveys using magnetometry are planned to further
define structures associated with mineralization. Structural targeting in conjunction with satellite alteration
mapping is currently in progress and results of this work will aid in more detailed exploration, including
geological targeting for follow-up ground truthing and sampling.
These works will be integrated with the updated core sampling results to aid drill targeting at Antonella.
Reconnaissance sampling in conjunction with preliminary mapping will continue in Antonella North where
a separate vein array has recently been identified (see January 6, 2026 & February 4, 2026 Daura news
releases). Initial reconnaissance sampling and mapping southeast of Antonella towards Highlands Silver
Corp.'s Bonita Project will commence when community' access is granted.
Technical Information and Quality Control / Quality Assurance
The infill sampled drill core was split in half using a diamond saw. Core is logged by the Company's
geologists on site who outlined the intervals to be sampled. The maximum sample length is
approximately 2 meters and sample lengths are adjusted according to lithological and/or mineralogical
contacts.
After sawing, one-half of the infill 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 a dedicated transport service under the close
supervision of Daura personnel to Actlabs Skyline Peru ("Actlabs") an arms-length laboratory, for
preparation and analysis. The entire sample was dried and crushed to 75% passing 2mm, with splits
pulverized to 95% passing 106 microns.
Gold was analyzed by 30g charge Fire Assay, with an Atomic Adsorption finish. Multi-element analysis
was carried out on a 4-acid digest aliquot by Inductively Coupled Plasma Optical Emission
Spectroscopy (ICP-OES) and over-range samples were subsequently determined by appropriate single
element analyses, in accordance with Actlabs standard procedures.
The internal quality assurance and quality control (QA/QC) program included the submission of 10%
quality control materials including field duplicates, blanks and Certified Reference Material (CRM)
standards.
Coarse rejects and pulps are retained in secure storage for future verification or testing as
required.
QA/QC results were reviewed by Geodex Consultants Ltd., a third-party independent
consultant, and were found to be within acceptable limits before being uploaded into Datashed by
Geomax Ltd., an independent arms-length database manager.
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.
