RUA GOLD Reports Auld Creek Drilling

Drill Results

RUA GOLD Reports Auld Creek Drilling

Results Including 2.1m @ 64g/t AuEq

Intersected 120m Below the Current Resource,

Demonstrating Significant and Open-Ended

Depth Potential

Vancouver, British Columbia--(Newsfile Corp. - June 16, 2025) - Rua Gold Inc. (TSXV: RUA) (OTCQB:

NZAUF) (WKN: A40QYC) ("

RUA GOLD

" or the "

Company

") is pleased to provide an update on its

gold-antimony exploration at the Auld Creek project in the Reefton Goldfield on the South Island of New

Zealand, reporting further high-grade gold-antimony intersections 120 meters below the current resource

estimate.

Highlights:

Auld Creek has an inferred resource hosted by two ore shoots, Bonanza and Fraternal. This

resource outcrops at surface.

The latest drilling increases the vertical extent of the resource

from 160m to 280m and remains open at depth.

Following up on the encouraging high-grade gold-antimony results from drillholes ACDDH026-028;

holes ACDDH030-33 intersected excellent high-grade mineralization with continuity of the strong

gold-stibnite (antimony sulfide) mineralization previously reported.

Assay results show:

ACDDH031: 2.1m @ 64.0g/t AuEq

1

(5.5g/t Au & 13.1% Sb) from 310m depth

ACDDH032: 2m @ 1.4g/t Au

from 296m depth

Current drilling is testing the Fraternal north prospect and Bonanza northeast prospect, where

surface soil geochemistry has confirmed the system is traceable over a 2.5km length.

Drilling in the second quarter will then probe further at depth and test its extent southward with the

goal of growing the current resource.

Antimony is in rising demand due to its vital role in renewable energy, batteries, defense, and

technology. Its supply is scarce and largely controlled by China, Russia, and Tajikistan, making it a

strategic material, especially during geopolitical tensions, which has caused prices to surge from

US$11,350 to over US$60,000 per tonne.

Robert Eckford, CEO of RUA GOLD commented: "

This is an exciting development to see high-grade

gold-antimony mineralization at Auld Creek that is 120m deeper than the current resource. Proving

out continuity at depth and growing this resource will be a key focus of drilling in the next quarter, while

simultaneously drilling the Cumberland-Galant deposit 3km to the south.

We continue to be focused on expanding the Auld Creek resource both north, south and at depth, with

intensified surface exploration showing early promise in identifying additional mineralization over its

2.5km length.

With Antimony being at the top of every nations' critical minerals lists, the importance of this resource

growth to both RUA GOLD and New Zealand is significant."

Using recent spot prices of gold and antimony, and applying a ~30% discount, the gold equivalent formula is based on AuEq = Au g/t + 4.3 x Sb%

using a Au price of US$2065/oz, Sb price of US$34,300 per tonne and 85% recovery.

GLOBAL SUPPLY AND VALUE OF ANTIMONY

Antimony is a critical metalloid primarily sourced from the mineral, stibnite.

It is highly valuable and

increasing in demand due to its versatility and has essential applications across renewable energy,

liquid battery metals, defence and technological sectors.

Due to its limited supply, predominantly controlled by China, Russia & Tajikistan, antimony is considered

a strategic material essential for supply chain security, particularly during periods of geopolitical

instability. This was heightened in September 2024, when China announced export controls on

processed antimony products. In response to these controls, nations have accelerated their efforts to

secure alternative sources of antimony to mitigate the risk of significant supply chain vulnerabilities.

The US, EU, UK, Japan, Canada and Australia all designate antimony as a critical mineral. On January

31, 2025, New Zealand also announced their Critical Mineral List which included antimony.

Reflecting heightened demand, the price of antimony has reached new highs, currently trading over

US$60,000 per tonne, a significant increase from US$11,350 per tonne at the start of 2024. This market

shift has intensified interest in the strategic antimony potential held by RUA GOLD.

EXPLORATION POTENTIAL

RUA GOLD commenced drilling at Auld Creek in December 2024. It has a targeted program to drill four

mineralised shoots identified from historical surface exploration work interpreted by the RUA GOLD

team over the past 3 months.

Auld Creek is situated between two past producing mines, Globe Progress mine, and the Crushington

Group of mines which collectively produced 933,000oz at 14.0g/t Au (Barry 1993). Auld Creek has three

historic adits but no commercial production from the reefs.

RUA GOLD has an inferred resource indicating 700,000 tonnes at 3.1g/t Au and 1.1% Sb for 67,000oz

of gold and 8,000 tonnes of antimony

1

(AuEq 110,000oz

2

). The resource is restricted to two of the four

known shoots. Soil geochemistry indicates the potential for discovery of additional mineralised shoots

over a strike length of 2.5km.

Four of the eight holes completed to date intersected 4-5m of strong visible stibnite (antimony sulfide)

mineralization in the Fraternal-Bonanza structure.

Results from ACDDH024, ACDDH025 confirm the approximate average gold grades, but report higher

antimony grades than the current resource estimate. Results from ACDDH027, ACDDH028 highlight

above average gold grades with narrow but high-grade antimony in ACDDH028.

Drilling of ACDDH030,31,32 and 33 (results pending, but structure intercepted) provide strong evidence

of the continuity of the Fraternal gold-antimony structure at depth, and the narrow high-grade intersection

of ACDDH031 has confirmed resource grade mineralization and continuity with the previously reported

drilling of holes ACDDH027 and ACDDH028.

Intensified surface exploration is showing very encouraging strong trends both north and north-west

confirming additional targets on the Fraternal North and Bonanza north-west extensions.

QA/QC Drill Core

Core samples were sent to SGS Laboratories, Westport for sample preparation. Samples were crushed

and pulverized to 85% passing 75 µm. The pulverized rock-chips were split into two samples: a ~50 g

sent for laboratory analysis, and the reject returned to RGL for pXRF analysis and storage. Pulverized

rock-chip samples were analyzed for gold (Au) by 50-g fire assay with AAS finish at SGS Waihi (SGS

Code FAA505); and for antimony (Sb) by Sodium Peroxide Fusion Analysis by ICP-MS at SGS Waihi.
