RUA GOLD Reports Significant Gold-Antimony Intercepts from Its Reefton Project

Rua Gold Inc. (TSXV: RUA) (OTCQB: NZAUF) (WKN: A40QYC) ("Rua Gold" or the "Company") is pleased to provide an update on assay results from its gold-antimony exploration at the Auld Creek project, within the Reefton Goldfield on the South Island of New Zealand; reporting strong antimony grades from current drilling.

Highlights: 

• Drilling of Auld Creek commenced in December 2024, holes ACDD024 and ACDD025 intersected 4-5m of strong visible stibnite (antimony) mineralization. 

• Assay results show: 

  • ACDDH024: 12m @ 12.2g/t AuEq¹ (1.9g/t Au & 2.4% Sb) from 105m depth

    • Including 2m @ 54.8 g/t AuEq¹ (3.8g/t Au & 11.9% Sb) 

  • ACDDH025: 8m @ 13.2g/t AuEq¹ (2.2g/t Au & 2.2% Sb) from 106m depth 

    • Including 3m @ 33.2g/t AuEq¹ (3.6g/t Au & 6.9% Sb) 

• 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. 

• Drilling has confirmed higher grade antimony mineralisation on the Fraternal shoot within a broader lower grade gold halo. Modelling suggesting a gentle plunge to the south, remains open to the south along strike and at depth with drilling commencing to the south to expand the existing resource. 

• Surface exploration is intensifying to target extensions to the Fraternal and Bonanza north and south, where it remains open over a 2.5km length.

Robert Eckford, CEO of Rua Gold commented: "The results from these two holes drilled at Auld Creek show increased antimony grades which is very encouraging. It further supports the fact that we are holders of New Zealand's largest antimony resource and are delivering on the commitment to our shareholders to build on our inventory of gold ounces and antimony tonnes at our Reefton project.

Drilling to date on Auld Creek antimony-gold prospect has improved confidence in the existing resource and provided detail on higher grade plunging shoots open to the south. We are focused on expanding the Auld Creek resource north and south, with intensified surface exploration to assist targeting additional mineralization over its 2.5km surface strike length.

This comes on the back of both gold and antimony trading at all time high spot prices and both commodities being announced on New Zealand's first ever critical minerals list."

1. 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 mineral sourced from stibnite (Sb₂S₃). In 2023, it was reported by the Critical Minerals Institute (CMI) as one of the scarcest of all critical minerals. Spot prices have risen as demand increases with its essential input into applications across renewable energy, liquid battery metals, defence and technological sectors.

Due to its scarcity and 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 continues to reach new highs, trading over US$50,000 per tonne, a significant increase from US$11,350 per tonne at the start of 2024.

EXPLORATION POTENTIAL

Auld Creek Focus

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 antimony². 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.

2. Please see the Company's technical report entitled, "Technical Report on Reefton Project, New Zealand", dated October 30, 2024.

Two of the four holes completed to date intersected 4-5m of strong visible stibnite (antimony sulfide) mineralization in the Fraternal-Bonanza structure. No significant mineralization was found in holes ACDDH022 and ACDDH023. Results from ACDDH024, ACDDH025 confirm the average gold grades of current resource estimate but report higher antimony grades. Full table of results are in Tables 1 and 2 of the appendices.

Ongoing drilling is targeting the southern plunging Fraternal gold-antimony shoot which remains open along strike and at depth.

Intensified surface exploration is focused both north and north-west to delineate drill 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 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

Drillholes sampled following 1-m sample intervals unless geological contacts (i.e. dolerite intrusions) dictated otherwise. NQ core was analyzed as whole core; therefore, only requiring cutting along sample intervals. PQ and HQ core were sampled as half core.

Drill core samples were sent to SGS Westport for sample preparation. Core was crushed to 75% passing 2 mm, and 1-kg split of material was pulverized (to 85% passing 75 µm). No split duplicates were collected during the crushing steps. Two scoops were taken from the pulverize bowl: one for laboratory analysis (~150 g) and the other for pXRF analysis (~100 g). The pulp reject is stored in Reefton.

Pulverized drill core samples were analyzed 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. The detection limit for Au by this method is 0.01 ppm. As part of SGS' internal quality control, SGS conducted repeat analyses, also at a rate of ~5%.
