Pattern Detected

Limited history shows two recent announcements with positive next-day price reactions, including this sampling update.

Recent Company History

In late 2025, Daura Gold reported high-grade surface sampling at Antonella, with standout assays up to 57.34 g/t Au and 128 g/t Ag, followed by a 7.78% next-day gain. The next day, the company granted 3,355,000 stock options at $0.35, which coincided with a stronger 60.87% price move. Overall, recent news combined exploration progress with corporate incentive alignment, and both events saw aligned positive price reactions.

Market Pulse Summary

The stock moved +7.8% in the session following this news. A strong positive reaction aligns with prior behavior, where this sampling news previously coincided with a 7.78% move and an option grant saw a 60.87% gain. High-grade assays up to 57.34 g/t Au and 128 g/t Ag have been key catalysts. However, investors have limited historical data to gauge consistency, and thin volume near $0.28 could make sharp moves vulnerable to reversal if enthusiasm around exploration results fades.

Key Terms

metallogenic belt technical

"Antonella is located in a prolific metallogenic belt hosting significant deposits"

A metallogenic belt is a geographic zone where natural deposits of metal ores, like copper, gold or zinc, are concentrated due to past geological processes. For investors, it acts like a neighborhood known for valuable real estate: companies operating there are more likely to find recoverable minerals, which can lower exploration cost and raise the potential payoff, but location alone doesn’t guarantee profitability because extraction, permitting and market prices still matter.

argillic alteration technical

"with silicification and argillic alteration halos up to 40 meters wide"

Argillic alteration is when rock is chemically changed by hot, mineral-rich fluids so that clay minerals replace the original minerals, leaving the rock soft and clay-rich like a sponge. Investors watch for it because these clay zones can mark where mineral-bearing fluids travelled (helping find deposits) but also create mining and processing challenges—clay can make excavation harder, lower rock strength, and complicate ore recovery.

magnetometry technical

"Geophysical surveys using magnetometry are planned to further define structures"

Magnetometry measures tiny magnetic fields around objects or areas using instruments, like using a compass to map invisible forces. Investors care because it reveals hidden features or problems — for example locating mineral deposits in exploration, checking components in manufacturing, or validating performance of medical sensors — which can reduce uncertainty, guide spending decisions and affect a project’s or company’s value.

fire assay technical

"Gold was analyzed by 30g charge Fire Assay, with an Atomic Adsorption finish"

Fire assay is a laboratory process used to accurately measure the amount of precious metals, like gold or silver, in a sample of ore or material. It involves heating the sample intensely to separate the metals from other substances, much like melting and purifying metal to determine its purity. This method is important to investors because it provides precise data on the metal content, helping to assess the value of mining operations or mineral deposits.

inductively coupled plasma optical emission spectroscopy (ICP-OES) technical

"Multi-element analysis was carried out ... by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES)"

A laboratory technique that uses a very hot ionized gas (plasma) to excite atoms in a sample so they emit light at wavelengths characteristic of each element; measuring those colors tells you which elements are present and in what amounts. Investors care because ICP-OES is a standard, fast way to verify material composition, purity and contamination for industries like mining, chemicals, batteries, semiconductors and environmental testing, affecting product quality, regulatory compliance and supply value.

qa/qc technical

"The internal QA/QC program included the submission of 10% quality control materials"

QA/QC stands for Quality Assurance and Quality Control, processes used to ensure products or services meet certain standards. Think of it as a way to check that a product is safe and works properly before reaching consumers, similar to how a chef tastes food before serving it. For investors, strong QA/QC practices indicate a company's commitment to delivering reliable, high-quality offerings, reducing risks and building trust.

certified reference material technical

"including field duplicates, blanks and Certified Reference Material (CRM) standards"

A certified reference material is a substance or sample with precisely measured properties and an official certificate that labs use to calibrate instruments and check testing accuracy, like a ruler for measurements. Investors care because reliable testing underpins product quality, regulatory approvals and compliance, and environmental or safety claims; using certified materials reduces the risk of costly recalls, failed audits or misleading results that can harm a company’s finances and reputation.

ni 43-101 regulatory

"Stuart Mills QP, is the Company's qualified person as defined by NI 43-101"

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

Vancouver, British Columbia--(Newsfile Corp. - December 2, 2025) - Daura Gold Corp. (TSXV: DGC) ("Daura" or the "Company") is pleased to announce high-grade surface sampling results and the delineation of vein extensions in the northern zone of the Company's flagship Antonella Project ("Antonella" or the "Project") in Ancash, Peru. The work confirms strong gold and silver mineralization and supports the continuity of Antonella's vein system to the north of the main project zone.

Antonella is located in a prolific metallogenic belt hosting significant deposits such as Antamina and Barrick's past producing Pierina gold mine. The Project's vein system is hosted in tertiary volcanic rocks of the Calipuy Group and controlled by NW-SE trending faults, with silicification and argillic alteration halos up to 40 meters wide.

Highlights of the Sampling Program:

• 31 rock chip samples were collected approximately 1km north of Antonella vein system with mineralization of Au and Ag.
  
  
• Standout samples of
  • 57.34 g/t Au & 125 g/t Ag; and
  • 24.63 g/t Au & 128 g/t Ag.
    
    
• Additional high grade gold samples include:
  • 6.52 g/t Au & 32.6 g/t Ag;
  • 3.47 g/t Au & 32 g/t Ag; and
  • 1.69 g/t Au & 21 g/t Ag.

"Assays from Antonella continue to deliver excellent results, as we uncover new zones of high-grade gold and silver mineralization," said Mark Sumner, CEO of Daura. "This discovery of high-grade gold and silver, north of our main project zone, further confirms the potential at Antonella. We remain excited to advance southeast toward Highlander's Bonita project while simultaneously prioritizing additional work on the highly promising veins identified in the north as exploration progresses."

Next Steps

Daura will continue geological mapping and sampling across the Antonella concessions, including northern (Estrella 02-19) and southern (Estrella 03-19) blocks, when the community's permission is obtained. Geophysical surveys using magnetometry are planned to further define structures associated with mineralization. The results will guide drill target definition for upcoming exploration programs.

Technical Information and Quality Control / Quality Assurance

Grab samples were collected by the Company's geologists and the individual samples, bagged, sealed and placed into sealed dispatch bags under the direct supervision of the Company's staff before being dispatched to Actlabs Skyline Peru, 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 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 the Company's technical team, led by Martin Zegarra, and were found to be within acceptable limits.

Readers are cautioned that grab samples disclosed are selected samples and may not represent true underlying mineralization.
