Golden Cross Confirms System-Scale Gold

Mineralization and Commences First Ever

Drilling at High Priority Aurora Target

Highlights

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 Mineralization

Assay 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 Overview

Golden 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 29

th

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.

Maiden Drilling Underway at the Aurora Prospect

Maiden drilling has commenced at the Aurora Prospect, a high-priority target located at the northwestern

end of the Reedy Creek Goldfield, interpreted to represent one of the most prospective structural

positions within the project.

Aurora is one of the most historically significant areas within the Reedy Creek goldfield. Artisanal mining

was carried out at Aurora in the late 1800s, and the scale of the historical workings is much larger than

other areas mapped to date. The presence of well-preserved historic underground mining tunnels

provides rare access for mapping and systematic sampling, offering exceptional geological insight.

Golden Cross has recently secured land access to the prospect, the first exploration company to do so

since the end of artisanal mining in the 1800s. With access in place, Golden Cross is now conducting

the first modern drill testing of the Aurora zone, with drilling recently initiated as part of the ongoing

exploration program.

Results from earlier drilling at Shepherd's Hill have further refined the geological model and directed the

Company's focus toward Aurora, where establishing continuity between historic gold mineralization and

potential mineralization at depth represents a key objective of the current drill program. Aurora is

expected to play a key role in the next phase of exploration as drilling continues and results are received.

Aurora Geological Mapping Confirms Gold and Pathfinder Signatures

As in the rest of the Reedy Creek Goldfield, mineralization at Aurora has developed within associated

shear zones developed within turbiditic siltstones, sandstones, and black-shale sequences.

Structural mapping has shown Aurora is situated along the F1 fold hinge of the Reedy Creek Anticline,

compared to Prince of Wales, which is situated on a northern parasitic fold limb (Figure 1).

Rock chip samples collected during the Aurora mapping program confirm the presence of gold

associated with arsenic. The best of these samples returned 5.22 g/t Au with 8,350 ppm As (Table 1).

Geological analysis describes the alteration as dominated by silica-sericite-carbonate with a well-

defined arsenic halo, consistent with an upper-system orogenic position.

Combined, the structural and geochemical data suggest that the Aurora Prospect has the potential to

host broader, more laterally extensive targets compared with steeper shoots at nearby prospects (e.g.,

Prince of Wales).

Shepherd's Hill: Early Gold Intercepts Provide Key Vectoring Information for Follow-Up Drilling

Further to the Company's news release dated 29

th

September 2025 announcing results from 393.21

metres of drilling on the first three holes at the Prince of Wales prospect, assays have now been

received for the four maiden drillholes at Shepherd's Hill, as well as a further four drillholes completed at

Wieneroider Ridge, Thompson's Reef, and Prince of Wales prospects, totalling 2,085 metres.

The most recent drilling reported here was completed at Shepherd's Hill, which is located southeast of,

and adjacent to, the highly prospective Aurora Prospect, where drilling is now underway. The first pass

drilling at Shepherd's Hill aimed to test the quartz reef system there and provide structural orientation to

future drill programs. Highlights from the Shepherd's Hill and Prince of Wales drilling include:

SHD002:

2.70m @

1.13 g/t Au

from 201.50m

Includes 0.60m @

2.92 g/t Au

from 203.10m

SHD003:

1.00m @

1.815 g/t Au

from 274.00m

SHD004:

1.00m @

0.93 g/t Au

from 213.00m

PWD008:

4.00m @ 0.86 g/t Au from 58.00m

Includes 1.00m @

1.88 g/t Au

from 61.00m

Importantly, every drillhole to date has shown well defined arsenic halos surrounding the gold-bearing

quartz veins, with lower-grade gold halos linking nearby reefs. This correlation between the gold and

arsenic is an important pathfinder tool that is enabling the company to vector in on gold mineralization.

Geological Model Strengthening, Clear Parallels to Victorian Gold Systems

Golden Cross is executing a model-driven exploration program, with oriented diamond drilling guided by

detailed structural mapping and interpretations of LiDAR and historical data. Structural and geochemical

results from the initial phase have been integrated into a robust geological model, which continues to

evolve as new drilling data is incorporated.

The Company believes it has unlocked key insights critical to understanding Reedy Creek mineralization

and importantly, has identified clear commonalities with other on-trend Victorian gold systems, including

Fosterville and Costerfield.

One potential parallel with Fosterville is the presence of depth-related sulphide zonation at Reedy Creek:

at Fosterville, gold and sulphide assemblages change systematically with depth, defining the

architecture of the system, this pattern is now emerging at Reedy Creek (Figure 5).

Applying a Fosterville-style zonation pattern to our own long section of Reedy Creek suggested the

presence of antimony to the southeast of the goldfield. A review of historic soil sampling confirmed

elevated antimony in this area. Further confirmation followed with stibnite noted in drill core from

Empress Reef, our southeasternmost drilling to date.

The appearance of this type of sulphide zonation pattern is not wholly surprising as the Reedy Creek

goldfield shares many other characteristics with Fosterville. Both projects feature turbidite-hosted gold

focused in shear zones and fold hinges, with carbonaceous shales aiding fluid trapping. Structural

mapping of Reedy Creek also shows steep vein dips, reverse/oblique kinematics, northwest-trending

structures, and anticlines with lensoid potential, consistent with known Fosterville-style controls and

analogous to the saddle-reefs of Bendigo.

Most importantly, these analogues are now enabling us to test predictions within our own model,

improving targeting confidence.

Results Pending for Empress & Welcome Reefs

Assay results remain pending for drilling completed at Empress Reef, and Welcome Reef (4 holes for

1406 metres of drilling).

Welcome Reef, part of the historic Ti Tree Creek Goldfield first discovered in 1859, is more than just

another historic Victorian goldfield - it is a cornerstone of Australia's gold rush heritage and financial

history. Mining records indicate that at least 9,000 ounces of gold

4

were extracted from the Ah Mouy

mine at Welcome Reef between June 1874 and September 1891, from approximately 10,500 tonnes of

ore grading an average of 25 g/t Au

.

The historical production figures cited above are sourced from period records and have not been

verified by the Company's Qualified Person. They are not reported in accordance with NI 43-101, should

not be relied upon, and are not necessarily indicative of mineralization on the Company's property or of

future exploration results. Please refer to the "Cautionary Statement" at the end of this news release for

further information regarding reliance on historic resources.

Historical reports note that the width and length of the vein increased with depth, and grades remained

remarkably consistent throughout the ore body

6

- an encouraging sign that the system may be far from

exhausted. Golden Cross plans to drill beneath the historic workings at Welcome Reef testing for gold

mineralization. The drill design will be based on detailed structural mapping of the historic workings

currently underway at the Welcome Reef area.

At Empress Reef, the southeasternmost drilling to date along the Reedy Creek goldfield, drill core shows

the presence of quartz carbonate veins containing multiple sulphide species such as sphalerite,

chalcopyrite, and arsenopyrite as well as stibnite (Figure 6). These sulphide species are important

pathfinders to potential gold mineralization.

QA/QC and Analytical Procedures

All samples reported from the current drilling program, as well as the rock chip samples collected during

the structural mapping campaign were processed under the Company's QA/QC protocol. Samples were

prepared and assayed at ALS Laboratories using industry-standard methods. The Company's QA/QC

program includes insertion of certified reference materials, blanks and field duplicates at regular

intervals. Assay data is validated and reviewed for quality as part of routine data verification.

In addition to the Company's QAQC practices, when assessing gold assays, the company re-submits

any sample interval that reports over 2g/t Au for analysis via Screen Fire Assay. Screen Fire Assays

separate and measure both coarse and fine gold fractions, improving accuracy and reproducibility of

nuggety samples and providing a clearer estimate of total gold content.

The QAQC regime for the sample batches of the Re-assay Program was modified as essentially every

sample in the program was a duplicate of a known result. Regular insertion of standards was replaced

with strategic insertion centred around confirmation of higher-grade samples. While sampling of

previously untested intervals from historic drilling was subject to the Company's regular QAQC protocols.

The original assays from GPAC's drill programs, as reported by GPAC, were all subject to quality control

measures appropriate for percussion drilling with duplicates, blanks and commercially available

standards with the expected results from the samples submitted. All assays were conducted by Onsite

Laboratory Services Ltd (ISO: 9001), located in Bendigo, Victoria, using fire assay techniques with a

25g or 50g charge and ICP or AAS finish. The quality control results are consistent.
