Crossroads Gold defines hydrothermal system at Pambula

Vancouver, British Columbia--(Newsfile Corp. - June 25, 2026) - Crossroads Gold Corp. (TSXV: CRG) (OTCQB: CRGCF) (FSE: FI1) ("Crossroads" or the "Company") announces the completion of a comprehensive historical data compilation and geological reinterpretation for the Pambula Gold Project (the "Pambula Project") in New South Wales, Australia. The work integrates mining records, Geological Survey data, structural interpretations and historical production information into a modern exploration framework (Figure 1). Mr. Rex Motton, CEO & Director of Crossroads, commented, " Pambula is emerging as a compelling district-scale gold system, with strong indications of structural continuity and sulphide-hosted mineralization that present an excellent opportunity for systematic exploration.

Although historical mining achieved excellent recovered grades of an estimated 30 g/t Au, modern exploration has been minimal, with most work in the 1980s focused on shallow, open-pit concepts. As a result, significant potential remains for deeper drilling targeting sulphide-hosted mineralization. Historical evidence suggests the field's decline was driven more by metallurgical limitations and lack of capital — not because the geological system was depleted.

Modern exploration methods and contemporary sulphide-processing technologies offer the potential to unlock substantial value across this underexplored district." The review indicates that the Pambula Goldfield, which produced more than 40,000 oz of gold at recovered grades of an estimated 30 g/t Au, remains significantly underexplored. Only 32 historical drill holes (2,515m total) have tested the Pambula Goldfield, with the deepest hole reaching 271m (DDH-P7) and no drilling below 230m vertical depth (Figure 2). Key findings: Broad, continuous gold mineralization at depth, highlighted by hole DDH-P7 returning 16m at 2.36 g/t Au from 94m, including 5m at 6.62 g/t Au , with no follow-up drilling completed on the main Victory ore shoot (Figure 3).

Untested deep structural targets, including a feeder-zone target at 400m depth and an additional similar style Crossroads-defined target at approximately 250-300m depth. Evidence of a large, structurally controlled hydrothermal system, including east-dipping lodes, brecciated corridors, sulphide-associated mineralization and north-plunging high-grade shoots. Increasing sulphide and arsenopyrite mineralization with depth, consistent with deeper sulphide-hosted gold systems in southeastern Australia.

Uncharacterized silver and antimony potential, with historical references to electrum, silver sulphosalts and stibnite but no systematic modern analysis. The reinterpretation suggests continuity between several major historical mines and highlights multiple district-scale targets beyond the historical workings, including the PRC32 magnetic anomaly, Hidden Treasure, Morning Star, Diorite structures and the Southern Yowaka corridor. Crossroads plans to integrate the compiled dataset into modern GIS and 3D models to support systematic exploration, including structural modelling, geochemistry, geophysics and deeper drilling.

Historical Geological Survey records and mining reports consistently describe: east-dipping lode systems; broad brecciated hydrothermal corridors; pyrite and arsenopyrite-associated mineralization; structurally controlled bonanza-grade shoots; and increasing sulphide mineralization with depth. The reinterpretation indicates that historical mining focused on isolated high-grade shoots within a much larger hydrothermal system.

Records describe underground development to an estimated 150m depth, with repeated references to widening ore zones and improving continuity at depth. The study also highlights significant unrecovered gold in historical tailings and sulphide concentrates, reflecting refractory mineralization and the metallurgical limitations of nineteenth-century operators—issues that modern processing technologies are now capable of addressing. Historical Drill Results Historical drilling at Pambula was limited and largely restricted to shallow tests around known workings in search of potential open-cut opportunities.

The key result from the dataset demonstrates broad, continuous gold mineralization at depth—an area that remains completely untested by modern exploration methods. Hole DDH-P7 - Key Historical Intercept Hole DDH-P7 returned 16m grading 2.36 g/t Au, including a higher-grade interval of 5m at 6.62 g/t Au. This intercept illustrates the potential for a broad zone of continuous gold mineralization at depth and represents one of the most significant results in the historical drilling record because it is the only drill hole in the central part of the Victory ore shoot that is below the old workings.

No follow-up drilling was completed in the immediate footprint of this intercept, and the zone remains open at depth below approximately 100m vertically. Untested Deep Exploration Target Multiple modern studies have projected the intersection of the Pilot Fissure with the Hidden Treasure and Killaloe fissures at depth as a potential bonanza-grade target. A 2018 review by Sapphire Resources identified a discrete deep structural target interpreted as a feeder zone to the broader system, based on structural modelling, lode-trend projections and historical high-grade production.

Sapphire proposed a drill hole to test the down-dip projection at approximately 400m, but the target was never drilled and remains untested. Crossroads' updated geological modelling places this high-priority target at approximately 250-300m depth from accessible drill sites near former hole DDH-P7, and it is planned for the second round of drilling. These deep targets represent the first systematic testing of the interpreted lode system at depths consistent with high-grade ore shoots in comparable southeastern Australian gold systems.

Silver Historical mining records document silver-rich sulphide mineralization associated with primary gold lodes at several mines across the Pambula Goldfield, including electrum and silver sulphosalt occurrences. Despite silver being referenced in multiple historical accounts, no systematic modern assay program for silver has been completed across the drilling dataset, with arsenic and antimony only analyzed in three historical holes. The potential scale and grade of silver within the system remains wholly uncharacterized.

Antimony Antimony-bearing sulphides, including stibnite, have been identified in historical records at Pambula in association with primary gold mineralization. Given the current focus on antimony as a strategic critical mineral across multiple jurisdictions including Australia and Canada, the Company intends to systematically assess antimony and silver potential as part of its planned drill program at Pambula. No modern multi-element analysis for these elements has previously been undertaken.

Gold-Pathfinder Elements A modern multi-element reassay program targeting arsenic, bismuth, tellurium and other gold-pathfinder elements could provide a materially improved understanding of the zonation and structural architecture of the system. Historical assay programs were generally single-element gold-only programs that would not have captured the broader geochemical signature now recognized as indicative of significant hydrothermal gold systems in southeastern Australia. Structural and Exploration Implications The reinterpretation provides an important framework for future exploration targeting across the Pambula Project.

The Company intends to integrate the historical data into modern GIS and 3D geological modelling platforms to support future targeting and drill planning. Several structural features identified in the study — including parallel lodes, branching fracture systems, crosscourse offsets and plunge-controlled ore shoots — are considered highly prospective targets for modern exploration techniques. The Company believes that the broader district remains underexplored by modern standards, particularly with respect to: systematic geochemistry; modern geophysics; structural modelling; and deeper drill testing of sulphide-hosted mineralization.

Beyond the deep targets described above, the Company has identified five initial separate exploration targets across the district that demonstrate scale beyond the historical workings, including the Eastern Fissure (including the PRC32 magnetic anomaly), the Hidden Treasure, Morning Star and Diorite structures, and the Southern Yowaka corridor. Other gold workings occur outside the central area but have not yet been assessed.
