Golden Cross Confirms System-Scale Gold Mineralization and Commences First Ever Drilling at High Priority Aurora TargetHighlights 4,000 metres drilled across 15 diamond holes at Reedy Creek confirming a large, continuous orogenic gold system, with gold intersected in every drillhole to date.Consistent gold mineralization with well-developed arsenic halos confirms drilling is intersecting the upper levels of a vertically extensive system, with geochemical and structural vectoring now pointing toward stronger mineralization at depth.Structural and geochemical signatures display clear parallels with major Victorian gold systems including Fosterville and Costerfield, where high-grade mineralization strengthens below arsenic-dominant upper zones.Maiden modern drilling has commenced at the Aurora Prospect, a historically significant, never-before-drilled target located on the fold hinge of the Reedy Creek Anticline, interpreted to have potential for broader and more continuous high-grade gold mineralization.Golden Cross is the first exploration company to secure land access to Aurora, a high priority target since the acquisition of Reedy Creek given its structural position and extensive history of artisanal mining.Assay results remain pending from Welcome Reef and Empress Reef, expected to refine targeting further and provide upcoming news flow.Vancouver, British Columbia--(Newsfile Corp. - December 15, 2025) - Golden Cross Resources (TSXV: AUX) (OTCQB: ZCRMF) (FSE: ZMLO) ("Golden Cross" or the "Company") is pleased to provide the following update on its ongoing exploration at the Reedy Creek Project, Victoria, Australia, where drilling, mapping, and structural analysis have confirmed a large orogenic gold system extending across multiple targets. Drilling to date has intersected gold mineralization in every drillhole, accompanied by well-developed arsenic halos that are characteristic of the upper levels of major Victorian gold systems. Structural interpretation and geochemical vectoring now indicate increasing prospectivity at depth, consistent with the architecture observed at deposits such as Fosterville and Costerfield. With exclusive land access now secured, Golden Cross has commenced the first modern drill testing at the high-priority Aurora Prospect, marking a key step toward testing for thicker and higher-grade gold zones.Golden Cross CEO, Matthew Roma, States:"Every hole drilled to date has intersected gold with well-developed arsenic halos, confirming that we are operating in the upper levels of a larger orogenic gold system. The grades we're seeing near-surface, coupled with our structural data, are now pointing us toward where the system gets stronger at depth, and the never before drill-tested Aurora prospect is emerging as the most compelling location to test for thicker, higher-grade veins. Rock chips returning up to 5.22 g/t Au highlight the strength of the system at surface and reinforce Aurora as a compelling drill target with room to grow at depth. We view this systematic, technical progress as a positive step in the right direction toward making a discovery."Gold Intersected in Every Drillhole Confirms System-Scale MineralizationAssay results received to date confirm that all diamond drillholes completed at Reedy Creek have intersected gold mineralization, supported by consistent arsenic pathfinder halos. This widespread mineralization confirms the presence of a large, continuous orogenic gold system rather than isolated vein occurrences. The distribution of gold and arsenic is interpreted to represent the upper portions of the system, providing important vectoring information to guide deeper follow-up drilling.Reedy Creek Drilling OverviewGolden Cross has now completed 4,000m across 15 diamond drillholes at the Reedy Creek Project. Of these 15 holes, 3 were previously reported (see News Release dated 29th September 2025), 8 are reported in this news release and 4 remain pending assay results. Drilling initially focused on confirming the presence of multiple vein sets, variable silicification and zones of sulphide mineralization consistent with orogenic-style systems. Drilling has now moved to targeting structures at the recently unlocked Aurora prospect.As reported in the announcement on September 29, 2025, the maiden drilling was designed to prioritize structural information to develop a precise three-dimensional exploration model to effectively target second phase deeper drilling aimed at testing the greatest potential for mineralization ("testing the ladder" method).Drilling to date has successfully intersected multiple target vein sets and associated zones of alteration, with orientated core providing key structural data such as measured vein orientations and fault relationships for Phase 2 drilling.
