Golden Cross Resources Commences Drilling at its Reedy Creek High-Grade Gold Project in Victoria, Australia

Summary:

• Golden Cross has commenced drilling at the Reedy Creek Gold Project, 10 km northeast of and contiguous to Southern Cross Gold's recent Sunday Creek gold discovery

• Historical drilling at Reedy Creek revealed high-grade gold intercepts including 11 m at 31.4 g/t gold and 2 m at 174.42 g/t gold¹

• Recent soil geochemical sampling also identified a ~3 km-long gold-in-soil geochemical anomaly

• Fully funded: Initial 2,000 metres of drilling at key targets will aim to expand known gold mineralization and support an additional fully funded 4,000 metres of drilling

Vancouver, British Columbia--(Newsfile Corp. - June 4, 2025) - Golden Cross Resources Corp (TSXV: AUX) (OTC Pink: ZCRMD) ("Golden Cross" or the "Company"), a company focused on high-grade gold exploration at the historic Reedy Creek Goldfield in Victoria, Australia, is pleased to announce it has commenced an inaugural fully funded 6,000-metre phased drill program to test and expand on key high-grade gold targets.

An initial 2,000-metre diamond drilling program comprises 15 shallow drill holes at the Prince of Wales & Wieneroider Ridge targets within the Reedy Creek Goldfield (Figure 1, below). This initial phase has been guided by LiDAR survey data, a review of recent previous drilling as well as the recently completed structural mapping. It is designed to systematically improve the structural and geological understanding of the targets and will aim to expand on the known mineralization. This will be achieved by targeting interpreted faults, shears, and quartz veins.

Enhanced geotechnical insight from the early drilling will support a further 4,000m of fully funded drilling. This drilling will be aimed at investigating extensions to vein systems at depth, as well as testing of adjacent ladder targets.

The drill targets have been identified from geological mapping of surface workings and are untouched by modern exploration techniques. They offer the potential to identify previously unrecognized mineralization that could be incorporated into the broader Reedy Creek exploration model.

Golden Cross Resources will have the option to field additional drill rigs later in 2025. This decision will be based on drilling results and will be guided by ongoing structural mapping running in support of the drilling program.

Management Commentary

"With drilling having commenced at Reedy Creek, our focus is to develop a deeper understanding of the structural controls on mineralization as we look to expand our drilling program. We expect to announce initial drill results later this summer," said Golden Cross CEO Matthew Roma.

About the Reedy Creek Project: Historic High-Grade Gold Intercepts

Located just 10 km northeast of Southern Cross Gold's recent Sunday Creek gold discovery, historical drilling at Reedy Creek points to a potential high-grade gold system. Significant intercepts¹ include:

• 2.0 m at 174.4 g/t gold
• 11.0 m at 31.4 g/t gold

These shallow intercepts demonstrate very high gold grades but were never followed up with deeper or systematic drilling. Golden Cross intends to apply modern structural, geochemical, and geological tools to define its scale and continuity.

~3km Gold-in-Soil Anomaly Suggests Potential Large-Scale System

Supporting Golden Cross' 6,000 metre drill campaign this summer is a recently outlined gold-in-soil anomaly stretching more than 3 kilometers in length and running parallel to a regional anticline -similar in style to structures hosting mineralization at Sunday Creek. Gold-in-soil anomalies are critical early indicators of mineralized systems, especially in epizonal deposits where gold is often closely associated with fault zones and vein swarms near surface.

The anomaly identified at Reedy Creek aligns with mapped folding and structural complexity, suggesting the potential for multiple pathways for gold deposition - a key requirement for high-grade, vertically extensive gold systems.

"Testing the Ladder": A Strategy That Delivered at Sunday Creek

Golden Cross is adopting the same exploration model that led to the breakthrough discovery at Sunday Creek: the "Testing the Ladder" approach. This strategy focuses on identifying stacked, steeply dipping high-grade gold bearing quartz veins (the "rungs" of a ladder) that can deliver multiple intercepts from a single drill hole when drilled at depth. The high-grade quartz veins forming these rungs are connected by a halo of lower grade mineralization within the intervening host rock.

Shorter historical holes from past drill campaigns could have potentially missed many of these deeper vein intersections. At Reedy Creek, past drilling at hole RWD01 reported the following grade intervals²:

• 0.8 m @ 21.7 g/t Au from 40.8 m
• 0.7 m @ 239.64 g/t Au from 68.7 m

By drilling deeper and along structurally favorable trends, Golden Cross aims to define the vertical extent, continuity, and true size of the potential system.
