Daura Gold Intersects High-Grade Gold & Silver Mineralization and Confirms Large Epithermal System from Phase One Drilling at Cerro Bayo

Highlights

• Multiple gold and silver intercepts returned from initial drilling at Cerro Bayo, with broad zones of near-surface silver mineralization encountered across multiple target areas.
• CBD26-001 returned 16.35 metres (m) @ 1.72 g/t gold-equivalent (AuEq), including 3.60 m @ 6.3 g/t AuEq.
• CBD26-005 returned 15.0 m @ 1.90 g/t AuEq and 3.60 m @ 6.08 g/t AuEq.
• Within CBD26-005, a high-grade silver interval returned 739 g/t Ag and 0.33 g/t Au over 1.8 m.

Vancouver, British Columbia–(Newsfile Corp. – May 21, 2026) – Daura Gold Corp. (TSXV: DGC) (OTCQB: DGCOF) (the “Company” or “Daura“) is pleased to report assay results from its phase one diamond drill program (“Phase One“) at the Cerro Bayo project located in the prolific Deseado Massif of Santa Cruz Province, Argentina (“Cerro Bayo“).

The 1,850-metre program comprised 18 diamond drill holes testing 10 priority targets across the 28,397-hectare property. Significant gold and silver mineralization was intersected in multiple holes during this first-pass drill campaign, including several higher-grade intervals that demonstrate the potential of the epithermal system.

“The Cerro Bayo and La Flora license areas form part of a very large hydrothermal field spanning more than 400 km² within the Deseado Massif, where multiple target areas identified by previous operators remained effectively untested by drilling,” stated Stuart Mills, VP Exploration at Daura Gold. “Phase One drilling successfully intersected broad zones of near-surface silver mineralization and higher-grade gold-silver intervals across multiple target areas, validating several key aspects of our geological model during Daura’s preliminary drill campaign.”

Highlight Intercepts

Hole CBD26-001:

• 16.35 m at 1.72 g/t AuEq^* (0.37 g/t Au, 88.96 g/t Ag) from 28.85 m; including
  • 3.60m at 1.43g/t gold (Au) and 321.7 g/t Ag (6.3 g/t AuEq) from 36.05 m.

Hole CBD26-005:

• 15.00 m at 1.90 g/t AuEq^* (0.07 g/t Au, 120.8 g/t Ag) from 58.7 m; including
  • 2.00m at 0.11 g/t Au and 427.4 g/t Ag (6.6 g/t AuEq) from 63.70 m, and
  • 1.70m at 0.16 g/t Au and 120.72 g/t Ag (2.0 g/t AuEq) from 68.30 m.
• 3.60 m at 6.08 g/t AuEq^* (0.18 g/t Au, 389.88 g/t Ag) from 86.4 m, including
  • 1.80m at 0.33 g/t Au and 739.53 g/t Ag (11.53 g/t AuEq) from 86.40 m.

Hole CBD26-012:

• 11.95m at 2.1 g/t AuEq (2.0 g/t Au, 6.8 g/t Ag) from 11.45 m, including
  • 1.95m at 8.83 g/t Au and 18.86 g/t Ag (9.1 g/t AuEq) from 17.15 m.

See Notes to Intercepts Table & Highlights

Additionally, broad zones of silver mineralization were encountered from surface in multiple holes, including:

• CBD26-001: 43.1 m at 44.3 g/t Ag; and
• CBD26-005: 34.1 m at 23.2 g/t Ag.

The broad near-surface mineralization encountered across multiple target areas supports the presence of a large and well-developed epithermal gold-silver system at Cerro Bayo, with potential for both shallow bulk-tonnage mineralization and higher-grade feeder structures at depth. The Company is continuing to refine targets and compile results in preparation for Phase Two drilling.

Mr. Mills continues, “Daura’s strategy has been to drill early while continuing to systematically refine and generate new targets across the district. Drilling successfully intersected low sulphidation epithermal veins and breccias associated with higher-grade gold and silver intervals across multiple target areas, confirming several key aspects of our geological model. Importantly, the scale and continuity of mineralization encountered suggest we are vectoring into a well-developed hydrothermal system with only our first phase of drilling. These drill results significantly enhance our confidence in the broader discovery potential at Cerro Bayo and we relish the opportunity to continue systematic, results-driven exploration.”

Notes to Intercepts Table & Highlights

• ‡ ^*Gold equivalent (AuEq)^* = Au + (Ag / 66) ^†. Assumes a recovery of 80% Ag and 100% Au given the project is early stage and there is no metallurgical test work to date.
• † Ag conversion uses a factor of 66, based on conservative, arbitrary Au & Ag prices, plus reduced Ag recoveries
• ^ Intersect lengths are recorded core lengths as true widths are not known at this time.
• * The potential quantity and grade is conceptual in nature as there has been insufficient exploration to define a mineral resource in the area and that it is uncertain if further exploration will result in the target being delineated as a mineral resource.

Phase Two Drilling & Exploration Program

Phase Two drilling at Cerro Bayo envisages step-out drilling from Phase One target tests and preliminary drill testing of recently generated targets that have been developed as part of the ongoing, systematic generative exploration program. The parallel advancement of both target generation, initial drilling and follow-up drilling is designed to create a sustained exploration pipeline with multiple opportunities for discovery across Daura’s growing Argentine portfolio.

At the La Flora project (“La Flora“), drill permit applications have been submitted, and the Company remains on track for an initial drill program during Q3/Q4 2026. La Flora represents an additional high-priority exploration opportunity where high-grade vein systems and visible gold have been identified at surface (see inset in Map 1).

QA/QC and Analytical Procedures

All of the drill core was split in half using a diamond saw and logged by the Company’s geologist 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.

Half drill core samples were collected under the supervision of the Company’s geological team and samples were transported by the Company to Alex Stewart Laboratories (“ASI“) in Perito Moreno, Santa Cruz, Argentina. The samples were dried, crushed to 80% passing 10 mesh, rotary split before being pulverized to 95% passing 106 microns pulp.

Gold and silver analyses were completed in Perito Moreno using 30 g Fire Assay with Atomic Absorption finish, with over-range analyses subsequently determined by appropriate single element analyses, in accordance with ASI’s standard procedures.

An aliquot of the pulp reject was shipped to ASI’s Mendoza laboratory for multi-element analysis consisting of aqua regia digestion and a 42-element suite analyzed by Inductively Coupled Mass Spectrometry (ICP-MS).

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 consultancy, 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.
