Star Metro - Sidney Resources Corporation Identifies District-Scale Structural and Hydrothermal System at Warren Project; Survey Confirms Strategic Claim Position Within Core Target Corridor

WARREN, ID / ACCESS Newswire / March 24, 2026 / Sidney Resources Corporation (OTCID:SDRC) ("Sidney" or the "Company") is pleased to announce the completion and initial interpretation of its recently conducted airborne magnetic and radiometric survey across the Warren District in Idaho.

The high-resolution helicopter-borne magnetic and radiometric survey across the Warren District has now been successfully completed, conducted at approximately 30-meter terrain clearance with 50-meter line spacing for comprehensive district-wide coverage. The resulting detailed geophysical dataset provides robust support for structural and lithologic interpretations, confirming SDRC's claims as centrally located within a prospective structural and hydrothermal corridor west/southwest of the historic town of Warren.

The integrated dataset has identified a district-scale structural and hydrothermal system, while also confirming that SDRC's claims are strategically positioned within a central, highly prospective portion of the system near and west/southwest of the historic town of Warren.

Survey Confirms Strategic Claim Position Within Core System

The airborne survey confirms that SDRC's claim package is not peripheral to the broader district, but instead occupies a central transition zone within the interpreted mineral system.

The Company's claims are situated:

• Across a broad structural and geophysical transition corridor

• Within a zone exhibiting overlapping magnetic and radiometric signatures

• Along a trend extending west and southwest from Warren toward Steamboat Summit

This positioning is considered highly favorable, as mineral systems are commonly focused along structural boundaries, intrusive margins, and zones of hydrothermal alteration-all of which are indicated within or immediately adjacent to SDRC's ground.

Magnetic Survey Defines Structural Architecture and Intrusive Framework

The magnetic survey outlines a large-scale geophysical framework across the Warren District, including:

• Distinct magnetic domains representing contrasting rock packages

• Multiple structural corridors trending NW-SE and NE-SW

• Evidence of cross-cutting fault systems and structural intersections

• Broad magnetic signatures consistent with intrusive influence

Importantly, SDRC's claims appear to lie across a central magnetic transition zone near Warren, where contrasting magnetic responses converge.

Such transition zones are commonly associated with:

• Structural breaks and offsets

• Intrusive contacts and margins

• Enhanced permeability for mineralizing fluids

This interpretation suggests that SDRC controls ground prospective for structurally focused mineralization rather than isolated or discontinuous targets.

"This is an incredibly successful magnetic survey. It has significantly advanced our understanding of the structural framework controlling mineralization in the Warren District," said Steve Dobson, Project Geologist. "The data has revealed a well-developed network of structural corridors and intersections characteristic of productive mineral systems. With follow-up induced polarization surveys planned for this summer, we expect to further refine these targets and continue evaluating the broader district-scale mineral system potential."

Radiometric Survey Confirms Widespread Hydrothermal Alteration and Fluid Activity

The radiometric survey provides strong evidence for hydrothermal alteration and fluid-related processes across the district, identifying:

• Elevated potassium (K) responses across central and northern zones

• Strong potassium-to-thorium (K/Th) anomalies indicative of alteration

• Localized uranium enrichment associated with fluid pathways

• Distinct geochemical zoning across the survey area

Notably, SDRC's claims overlap portions of the central and west-central radiometric response, where variability and elevated signatures suggest active or historic hydrothermal systems.

Potassium enrichment relative to thorium is widely recognized as an indicator of sericite alteration, commonly associated with mineralized environments.

Integrated Interpretation Identifies Multiple High-Priority Target Zones

The true significance of the survey lies in the convergence of independent datasets.

When magnetic and radiometric results are integrated, SDRC has identified zones where:

• Major structural features intersect

• Magnetic boundaries and disruptions occur

• Hydrothermal alteration (high K/Th) is present

• Radiometric signatures suggest fluid movement

Importantly, several of these overlapping signatures occur on or immediately adjacent to SDRC's claim package, particularly in areas surrounding and extending west/southwest of Warren.

These coincident signatures represent priority exploration targets, as they indicate areas where structure, alteration, and fluid pathways intersect-key components of mineral system development. The broader implications of these integrated results provide important context for understanding the scale of the system at Warren:

Geological Context and System Scale

The scale and continuity of the geophysical responses at Warren are consistent with large, structurally organized hydrothermal systems observed in established mineral districts.

In particular, the data indicate:

Kilometer-scale structural organization

Broad, laterally continuous alteration signatures

Evidence of multiple phases of fluid activity

These characteristics are commonly associated with mineral systems where historic mining has only exploited a portion of a much larger geological footprint.

Importantly, these comparisons are made strictly at the system scale-not at the deposit or resource level. The current geophysical results do not define grade, tonnage, or economic potential, but do indicate that the Warren District hosts a robust and well-developed mineral system capable of supporting multiple target zones.

District-Scale System Confirmed

The integrated results support a critical advancement in the Company's understanding of the Warren Project:

The property hosts a continuous, district-scale mineral system characterized by structural complexity, intrusive influence, and widespread hydrothermal alteration.

SDRC's claims are positioned within a central convergent zone of this system, rather than outside of it, significantly enhancing the exploration potential of the Company's ground.

Advancing Toward Drill-Ready Targets

The results of the airborne survey represent a major technical milestone for SDRC, clearly defining the key components of a district-scale mineral system directly across the Company's claim position.

Magnetic data has outlined a robust structural framework, while radiometric responses confirm widespread hydrothermal alteration and fluid activity. The convergence of these datasets has allowed SDRC to identify multiple high-priority target zones where structure, alteration, and fluid pathways coincide-critical ingredients for mineralization.

Importantly, these signatures are not isolated elsewhere in the district, but occur on or immediately adjacent to SDRC's claims, confirming the Company's strategic position within the core system corridor near and west/southwest of Warren.

With this foundation now established, SDRC is advancing rapidly toward execution, including:

• Refinement of structural interpretation and target ranking

• Ground truthing and surface sampling across priority zones

• Integration with historical workings and known mineral occurrences

• Evaluation of follow-up geophysical methods, including induced polarization (IP)

• Advancement toward drill targeting and exploration planning

These steps are designed to transition the project from geophysical interpretation to drill-ready targets, positioning SDRC for the next phase of value creation.

CEO Commentary:

"These results represent a major step forward in our understanding of the Warren District and reinforce our long-held belief that this is a large, structurally controlled mineral system," said Sean Rae Zalewski, CEO of Sidney Resources Corporation.

"What is particularly encouraging is that our claim position sits within a central corridor near and west of Warren where structure, alteration, and fluid signatures converge. That combination is exactly what we look for when defining high-quality exploration targets."

"At a system level, we are seeing structural and alteration characteristics that are consistent with those observed in well-known mineral districts, including portions of the Tintina Gold Province and the Cripple Creek District. These comparisons are qualitative and speak to the scale and organization of the system, not to grade or economic potential."

"We've now moved beyond concept and into clearly defined, data-driven targets. With follow-up work already planned, including induced polarization surveys and field validation, our focus is on advancing these zones toward drill-ready status and unlocking the broader potential of the district."
