$SDRC Update: Significant Intercept of Targeted Quartz Vein System at Warren District Project:

Sidney Resources Corporation (OTCID:SDRC) is pleased to report the successful underground interception of the targeted quartz vein system at its Warren District Project in Idaho.

The encountered vein displays intense alteration and textures unlike previous intersections in the area. The quartz is heavily altered, soft, and exhibits a greasy character, accompanied by strong iron oxide staining and prominent green/yellow mineralization.

Geological observations indicate a well-developed shear-hosted zone with evidence of multiple fluid events — consistent with a robust, sulfide-rich hydrothermal system.

Importantly, this high-intensity zone was intercepted earlier and appears more developed than anticipated in the current modeling, suggesting we have intersected the primary structural conduit rather than peripheral halo material. These characteristics are highly encouraging for potential free-milling gold mineralization.

Samples from the intercept have been collected and are being prepared for assay at independent third-party laboratories. This data will contribute to the growing dataset supporting future mineral resource estimation work.

We set the target. We hit the structure — and it looks stronger than modeled.

Further updates will follow as assay results and underground development progress. Cuts/Samples from this intercept have been sent to SGS and Florin Labs.

$SDRC Incredible video, please watch the entire 11 minutes before you form your opinion : https://t.co/41194ptxW9

More than anything, in my opinion, the OTC needs to remember we are invested in a STARTUP #mining company. These things take patience, but the long-term reward can be life-changing. Ignore the day-to-day noise and stay focused on the bigger picture. This video really helps put that long-term vision into perspective.

$sdrc question from an investor and response.

We are under a lot of NDA’s right now so it’s hard to share material information.

I am very excited for everything that is occurring, and I could not be more encouraged

The mining team made huge progress over the last several days and took actions that will save tens of millions of dollars in exploration costs over the next five years

These efforts will aid expansion and create more efficiencies moving forward

Very grateful to the hard and impactful work @HallySDRC and @wfmining Park consistently doing.

Nothing is slowing down and everything is going incredibly well.

We have had a ton of people reach out with their gratitude on the roads being opened by our company in the area as well.

$SDRC Q1 FY2026 Update – Advancing the Warren District Project ⛏️🇺🇸

🔗https://t.co/nc1VIvmomy

Q1 FY2026 marked another major advancement period for Sidney Resources Corporation as the Company continued progressing underground development, infrastructure expansion, metallurgical testing, permitting initiatives, and strategic growth activities across the Warren District Project in Idaho.

Operational Advancement – Lucky Ben Development

During the quarter, the Company completed more than 450 feet of underground drift development, including construction of a downward ramp from the main tunnel to a newly established working level.

These efforts resulted in the successful interception of the Little Giant Vein system, where systematic sampling and geological evaluation activities are now underway as SDRC continues building a comprehensive geological and assay database to support future Mineral Reserve Estimate work and long-term resource modeling initiatives.

Infrastructure & Permitting Progress

Construction activities associated with the Company’s new milling facility were substantially completed during the quarter, with major processing equipment moved into position.

The Company also continued advancing permitting efforts associated with the proposed movement of approximately 25,000 tons of historically mined material to the milling facility. The proposed Operations Plan has now been deemed complete by the U.S. Forest Service.

Additional engineering work was completed on a redesigned access road intended to improve safety, efficiency, and environmental stewardship while supporting modern mining and transportation requirements.

Metallurgy, Rare Earths & Strategic Minerals

Metallurgical testing and process development efforts remained ongoing throughout the quarter, including continued collaboration with independent laboratories focused on recovery challenges associated with precious metals, platinum group metals, rare earth elements, and strategic minerals identified within the Warren District Project.

The Company also:
⚫️ Applied for two DOE federal grant opportunities
⚫️ Advanced bioremediation initiatives
⚫️ Continued laser technology development efforts
⚫️ Submitted samples into federally funded rare earth recovery programs

Strategic Update

Sidney Resources Corporation’s executive management team and Board of Directors are actively evaluating multiple joint venture opportunities, as well as potential mergers and other forms of strategic corporate activity.

[Sean-Rae Zalewski @SeanRaeZalewski]

While we pursue significant next steps for the future of $SDRC @SDRCMINING we had a Great follow up call with a lab doing work with DOD and DARPA on Thursday.

A little of why are in conversation.
Iridium (the platinum-group metal) is a strategic/critical material for the U.S. Department of Defense (DOD), with relevance to DARPA’s efforts on supply chain resilience and advanced technologies. “

Key Defense Applications of Iridium
Iridium’s extreme properties—highest corrosion resistance of any metal, very high melting point (~2,446°C), hardness, and ability to withstand extreme temperatures and oxidizing environments—make it essential where failure is not an option:

• Aerospace and aircraft engines: Iridium alloys harden platinum and are used in high-temperature components that endure extreme heat and stress.
• Guided missile systems: Critical for precision components in propulsion or high-reliability environments.

• Satellite thrusters and rocket engine nozzles: Iridium-lined combustion chambers and catalyst beds (e.g., for hydrazine thrusters) resist erosion and thermal shock in space propulsion.
• High-temperature sensors, thermocouples, and crucibles: For military/aerospace testing and manufacturing under extreme conditions.

• Other electronics/radar/semiconductors: Used in spark plugs, backlit displays, computers, and radar screens with military applications.
These uses tie directly into DOD platforms (jets, missiles, satellites) and emerging needs like hypersonics or advanced propulsion.

Why It’s a Critical Supply Chain Concern for DOD/DARPA

• Extreme rarity and low yields: As discussed previously, global mined grades are typically <0.1 ppm, with production ~7–9 tonnes/year dominated by South Africa (Bushveld) and some Russian output. This creates single-point vulnerabilities. ($SDRC has multiple independent assays showing multiple ppm per ton consistently)

• DOD/DLA recognition: The Defense Logistics Agency (DLA) Strategic Materials lists iridium explicitly, noting its uses in aircraft engines, missiles, etc. The U.S. has near-total import reliance for PGMs (platinum-group metals, including iridium), with a very small National Defense Stockpile (e.g., historically ~15 kg of iridium).

• Geopolitical risks: Supply is concentrated; disruptions (e.g., from South Africa instability or Russia sanctions) could impact defense readiness. PGMs are often flagged in critical minerals assessments for economic and national security.

• DARPA’s role: DARPA runs programs like OPEN (Open Price Exploration for National Security) with USGS to improve transparency in critical materials pricing, supply/demand forecasting, and resilience—explicitly including materials vital to DOD. While OPEN focuses more on broader commodities (e.g., rare earths, lithium), it addresses the same class of vulnerabilities affecting iridium/PGMs. DARPA also funds efforts on domestic processing, separation technologies, and resilient supply chains for strategic minerals.

In short, iridium’s irreplaceability in high-performance military systems, combined with its tiny production volumes and foreign supply dependence, makes securing its supply chain a national security priority. DOD/DARPA focus on it (via stockpiling, R&D, forecasting, and diversification) aims to prevent disruptions that could degrade capabilities in aerospace, missiles, and space systems. Recycling and efficiency improvements are also key, as primary supply is inherently limited.
