RUA GOLD Reports High-Grade Gold Results from Supreme
and Caledonian in the Reefton Goldfield, New Zealand
Rua Gold Inc. (TSX: RUA | NZX: RGI | OTC: NZAUF | FSE: X9R) (“RUA GOLD" or the "Company") is
pleased to provide an update on recent drilling and surface sampling results from its regional
exploration program across the Reefton Project on the South Island of New Zealand.
The Company’s CEO Robert Eckford commented: “These results continue to demonstrate the
broader potential of the Reefton Goldfield. While Auld Creek remains our primary development
focus, recent success at Supreme and Caledonian highlights the strength of our regional
exploration strategy and the scale of opportunity across the district.
We continue to hit high-grade intercepts while step-out drilling has nearly doubled the strike
extent of known mineralization and extended the system to depth at Supreme. With further robust
geochemical results from Supreme, together with encouraging results from Caledonian, we
believe the scale, grade and repeatability can support meaningful resource growth across the
district.
This is precisely what we aim to achieve through our regional exploration program—expanding
beyond our core assets, validating new targets, and demonstrating that Reefton is a district-scale
opportunity for RUA GOLD.”

Highlights:
• The Supreme resource, previously explored by OceanaGold as a potential satellite pit
to Globe Progress mine, hosts an Inferred Mineral Resource of 1.46Mt @ 1.96g/t,
containing 92koz Au
(1)
. These step-out holes indicate the potential for a high grade
shoot.
• This broad step out increases down-plunge extent of the Supreme resource from
250m to 400m and extending mineralization to approximately 230m depth, with the
system remaining open to the south-southwest.
• Highlighted assay results from Supreme SPDDH003: 0.9m @ 26.9g/t Au from
178m in hole
• Highlighted assay results from Caledonian CLDDH005: 4.0m @ 6.9g/t Au from
265m, including 1m @ 11.5 g/t Au
• All Caledonian drill holes intersected the host quartz structure, with three out of six
holes returning significant mineralization, demonstrating the coherence and extent
of the target zone.
• Mineralization has been intersected 186m below historical workings at Caledonian,
further highlighting untapped depth potential of the Reefton deposits and validating
RUA’s exploration strategy.

SUPREME EXPLORATION UPDATE
The updated 2026 NI 43-101 technical report outlines an Inferred Mineral Resource at Supreme
of 1.46Mt @ 1.96g/t Au, containing 92koz Au
(2)
. This estimate does not yet incorporate recent
drilling results, indicating clear potential for resource growth.
Results from SPDDH002, along with mineralized quartz zones intersected in SPDDH003 and
SPDDH004, confirm that the Supreme system remains open at depth and along strike. Soil
geochemistry also indicates potential extensions to the north.
Drill Results Summary:
• SPDDH001 intersected the targeted structure, confirming continuity of the mineralised
system despite returning narrow, lower-grade intervals. These results support the
interpretation of discrete high-grade shoots within a broader mineralised corridor.
• SPDDH002 returned 3.1m @ 3.2g/t Au from 202m and 7.0m @ 1.2g/t Au from 230m,
demonstrating the presence of both high-grade intervals and broader zones of sulphide-
hosted mineralization typical of large hydrothermal systems. Shear-hosted deposits like
Supreme have the potential to host significant volumes and high grades.
• SPDDH003 confirms that high-grade gold at Supreme is not a one-off hit but is associated
with a broader mineralized corridor that is open at depth. As well as significantly
increasing the down plunge extent of mineralization at Supreme, the hole returned 0.9m
26.9g/t Au from 178m, the second-highest intercept ever recorded at the prospect,
within a wider zone of quartz veining and arsenopyrite mineralization (Figure 4).
• SPDDH004 intersected a low-grade shear zone, returning 5.4m @ 0.15g/t Au from
168.5m.

The 2025 drilling program confirms that Supreme hosts a coherent structural system capable of
supporting both broad mineralised zones and discrete high-grade shoots. Future work will focus
on testing extensions to the north, along strike, and at depth, as well as identifying parallel
structures.
A broader regional study is also underway to better understand the structural controls within the
north-south trending mineralised corridor. This study will assist the technical team when
planning more aggressive step outs that target multi-million-ounce deposits in the Reefton area.


CALEDONIAN EXPLORATION UPDATE
At Caledonian, RUA GOLD completed 1,579m of diamond drilling designed to test extensions
beneath the historic mine. The program successfully extended the known mineralised system
approximately 170m below historical workings and across a 270m strike length, confirming that
gold mineralisation continues well beyond the limits of the old mine.
Drilling consistently intersected the targeted quartz reef structure, with geological logging
confirming the presence of shearing, quartz veining, and arsenopyrite-bearing mineralization.
These results demonstrate that Caledonian is a coherent mineralised system with strong
potential for further growth down-plunge and along strike.
Drill Results Summary:
• CLDDH003 returned 3m @ 2.66 g/t Au and intersected an arsenopyrite-rich mineralised
halo, a style commonly associated with the margins of higher-grade gold shoots. This
supports the interpretation that Caledonian is not a narrow isolated vein system, but
rather a broader mineralised hydrothermal system with potential for higher-grade zones
to occur adjacent to or within these wider sulphide-rich envelopes.
• CLDDH004 intersected two discrete high-grade gold intervals of 1.0m @ 6.17 g/t Au
from 158.0m and 1.0m @ 6.96 g/t Au from 162.0m, reinforcing the continuity of
mineralisation. The hole intersected, with the close spacing of the intervals suggesting a
structurally complex mineralised zone rather than a single isolated vein.

5
• CLDDH005 was the standout hole, returning 4.0m @ 6.9 g/t Au from 265.0m (Figure 5).
Mineralisation persists 170m beneath the historic mine workings and remains open at
depth, intersecting. Importantly, the strongest mineralisation is associated with a
structurally complex zone of metasediments, quartz veining/stockwork, graphitic
alteration and abundant arsenopyrite (Figure 6).

The program has also generated valuable structural data, which will be incorporated into a 3D
geological model together alongside aeromagnetic data to refine targeting for future drilling.
Once this reinterpretation is complete, RUA GOLD will reassess Caledonian and determine the
most effective next phase of drilling.

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
All core samples sent for laboratory analysis was HQ sized, ½ core sampled to lithological
changes. Control samples (certified standards and uncertified blanks), along duplicates, are
inserted at a target 5% insertion rate. Results are assessed for accuracy, precision, and
contamination on an ongoing basis. Core samples were sent to SGS Laboratories, Westport for
sample preparation. SGS is independent of the Company. 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.
