RUA GOLD Expands High-Grade Intercepts at Depth at Auld Creek: 5.9g/t AuEq over 9m and 48.3g/t AuEq over 1.25m

Drill Results

RUA GOLD Expands High-Grade Intercepts at

Depth at Auld Creek: 5.9g/t AuEq over 9m and

48.3g/t AuEq over 1.25m

Vancouver, British Columbia--(Newsfile Corp. - April 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 improved gold grades from current drilling in diamond drillholes ACDDH026,

ACDDH027, ACDDH028.

Highlights:

Following up on the last high grade results from the Company, the next holes intersected broader

zones of gold in hole ACDDH027 and narrow but strong gold-stibnite (antimony sulphide)

mineralization in ACDDH028.

Assay results show:

ACDDH026: 2.1m @ 1.25g/t Au

from 175m depth

ACDDH027: 9m @ 5.9g/t AuEq

1

(5.2g/t Au & 0.16% Sb) from 159m depth

ACDDH028: 1.25m @ 48.3g/t AuEq

1

(13.3g/t Au & 8.1% Sb) from 210m depth

ACDD024,025 confirmed higher grade antimony mineralisation on the Fraternal shoot, the recent

drilling ACDDH27,28 indicates an improvement in gold grade with depth.

The gold grades on the Fraternal shoot plunge to the south, current drilling is testing 80-100m

below the current resource envelope, before pivoting to testing the northerly extensions of the

Fraternal ore body.

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

resource outcrops at surface and is continuous to 160m vertically and open at depth.

Surface soil geochemistry strongly endorses extensions to the Fraternal north prospect and

Bonanza northeast prospect, confirming the system is traceable over a 2.5km length.

Robert Eckford, CEO of RUA GOLD commented: "

It is encouraging to see an improvement in gold

grades with depth on the Fraternal lode, and the continuation of high-grade antimony accompanying

the gold in narrow plunging shoots.

Drilling to date on Auld Creek antimony-gold prospect has increased confidence in the existing gold-

antimony resource and highlighted higher-grade plunging shoots that remain open to the south. We

are focused on expanding the Auld Creek resource both north and south, with intensified surface

exploration showing early promise in identifying additional mineralization over its 2.5km length."

Note that AuEq amounts have been calculated 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 August 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$50,000 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 at Auld Creek indicating 700,000 tonnes at 3.1g/t Au and 1.1% Sb

for 67,000oz of gold and 8,000 tonnes of antimony

2

(AuEq 110,000oz

3

). 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.

Ongoing drilling is targeting the southern plunging Fraternal gold-antimony shoot which remains open

along strike and at depth.

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.

TECHNICAL INFORMATION

Simon Henderson CP, AUSIMM, a qualified person under National Instrument 43-101

Standards of

Disclosure for Mineral Projects

and Chief Operating Officer and a director of RUA GOLD, has reviewed

and approved the technical disclosure contained herein. Mr. Henderson has participated in the

geochemical sampling, and mapping programs to verify that they have been conducted in accordance

with standard operating procedures. Mr. Henderson has verified the data disclosed by running checks

on the location, analytical, and test data underlying the information in the technical disclosure herein.

QA/QC Drill Core

Rock 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.

QA/QC Soil Samples

Pre-planned soil sampling points on a 20 m x 100 m grid were loaded onto a handheld GPS for

guidance. A spade was used to acquire a ~1.0 kg sample from the C horizon, which was put in a wet-

strength paper sample bag with wire ties. Sample information was logged in a notebook in the field,

including sample ID, depth, color, horizon, slope, sample description, sampler, basement, and

comments. Each sample was photographed in the field alongside the GPS with coordinates visible and

each sample site marked in the field with biodegradable flagging tape. Samples were taken back to

RUA GOLD's Reefton facility for preparation. The sample information was entered on.csv files and

uploaded to an SQL database.

Samples were dried in a customized incubator, set at 38°C, for a minimum of two days. Once the

samples were fully dried, they were sieved to <180µm in size. A sub-sample of 30-50g was scooped

from the <180 µm size fraction for analysis. The remaining material was retained and stored in Reefton.

The fine-sieved (<180µm) soil sub-sample was first analyzed in RUA GOLD's Reefton facility using a

Olympus Vanta

pXRF analyzer; and then on to ALS Brisbane, Australia, for low-level gold analysis using

Au-TL43; trace level Au by aqua regia extraction with ICP-MS finish. Detection limit 1 ppb Au.

Field duplicates were collected every 20th sample and underwent the same sample collection and

preparation process outlined above. Duplicates were checked and validated by RUA GOLD's Isogonal

data validation system to ensure compliance.
