RUA GOLD Reports High-Grade Gold Results from Supreme and Caledonian in the Reefton Goldfield, New Zealand
RUA GOLD Reports High-Grade Gold Results
from Supreme and Caledonian in the Reefton
Goldfield, New Zealand
Vancouver, British Columbia--(Newsfile Corp. - April 7, 2026) - Rua Gold Inc. (TSX: RUA) (NZX: RGI)
(OTCQX: 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.
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.
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."

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.
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.

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

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.
