- 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 AuEq1 (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."
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 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 antimony1 (AuEq 110,000oz2). 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.
