RUA GOLD Completes the Second Phase of Surface Exploration and Drill Targeting at the Glamorgan Project, New Zealand
RUA GOLD Completes the Second Phase of
Surface Exploration and Drill Targeting at the
Glamorgan Project, New Zealand
Vancouver, British Columbia--(Newsfile Corp. - May 13, 2025) - Rua Gold Inc. (TSXV: RUA) (OTCQB:
NZAUF) (WKN: A4010V) ("
RUA GOLD
" or the "
Company
") is pleased to announce the completion of
the second phase of surface exploration on its Glamorgan Project, an epithermal gold system in the
Hauraki Goldfield, North Island, New Zealand.
The Hauraki Goldfield is a major epithermal gold province, with over 50 historic mines having produced
more than 15 million ounces of gold. The Glamorgan Project lies adjacent to OceanaGold's
Wharekirauponga deposit, with Indicated Mineral Resources of 1.4Moz at 17.9 g/t Au and is scheduled
to enter construction in the second half of 2025
1
.
Highlights:
The Company has completed its second phase of surface exploration, identified initial drill targets,
and will submit its Access Agreement application at the end of May.
Results indicate classic features of a major epithermal gold-silver system and are identical to the
surface features of neighboring OceanaGold Project, Wharekirauponga.
Four significant gold-arsenic soil anomalies trending north, north-east and north-northwest strike
out individually over 4 kms in length.
Rock chip samples containing up to 43 g/t Au highlight specific targets for evaluation, coincident
with the intersection of two gold-arsenic soil anomalies.
TerraSpec soil and clay mineralogy has identified a zonal clay distribution that reflects high-level
epithermal alteration coincident with gold anomalism.
Ground-based geophysics Controlled-source Audio-frequency Magnetotellurics (CSAMT) has
identified three major resistive structures coincident with surface alteration and gold mineralization.
These resistive structures may represent pervasive silica-quartz at depth - key criteria for targeting
the drilling within a major epithermal gold system.
All of the above results are being uploaded to the VRIFY AI-platform, where geological modelling is
starting to assist in the systematic identification and ranking of drill targets.
Simon Henderson, COO of RUA GOLD, commented: "This comprehensive, district-wide surface work
has provided valuable new information, highlighting not just one, but three significant zones of potential
mineralization for drill testing. These targets will be included in the Access Agreement for drilling, which
is scheduled for submission at the end of May 2025.
Following detailed surface geological mapping, comprehensive soil geochemistry, specialist clay
mineralogy, ultra-high resolution UAV magnetics, and proven depth-penetrating CSAMT geophysics,
three significant zones have emerged as high-potential targets for drill testing. High-grade rock chip
samples further support the potential to discover a major epithermal gold-silver vein system.
Results from this inaugural district-wide program are now streaming in and are being compiled,
reviewed and actively prioritized in partnership with the VRIFY AI-platform to confirm and prioritize the
drill program. The exploration team is excited to advance to the drilling phase of this unique and
prospective target area."
Program Overview
Exploration activities - including extensive geological mapping, TerraSpec clay mineralogy, and ultra
detailed magnetic and resistivity surveys - have focused on four major alteration cells that envelope
these structures. These cells are directly associated with surface quartz veins, platy quartz after calcite,
quartz-adularia minerals, and sinter-like textures, all indicative of the high levels of an epithermal gold-
silver system.
The principle components of the surface work are detailed below.
Geological Mapping
Exploration in the first quarter of 2025 included the completion of geological mapping across the major
drainages within the Glamorgan prospect, along with detailed examination of areas exhibiting intense
alteration and mineralization identified in Stage 1. The Company also completed follow-up testing of the
significant gold grades (8-43.1 g/t Au) previously reported in rock float and insitu rock samples (reported
on January 25, 2025). Additional rock chip sampling (2-8 g/t Au) has identified key areas proximal to
resistive zones and high-level clay alteration.

TerraSpec Clay Mineralogy
A TerraSpec 4 High-Res portable spectrometer was used to analyze all soil and rock-chip samples, as
well as available historical drill core. The hyperspectral reflectance data collected were interpreted using
the cloud-based AI software program, aiSIRIS.
Anomaly A trends north-northwest for 4.2 kms with conjugate gold-arsenic trends extending in a
northeast direction (Anomalies C and D). Montmorillonite clays mirror this anomaly, indicating
strong structural control on fluid flow along this trend.
Anomaly B trends northerly, following north to northeasterly quartz veins mapped over 4 kms that
remain open to the north and south. The southern end of this anomaly coincides with historical
mine workings. This anomaly is highlighted by strong illite clay alteration enveloping quartz-calcite
veins observed in mapping.
Anomalies C and D trend northeast, parallel to insitu quartz veining in the Phoenix Stream
(Anomaly C), and silica-clay alteration along Wires Ridge (Anomaly D) (Figure 2).

Magnetics
Ultra detailed UAV magnetics flown by the RUA GOLD team highlight strong alteration (de-
magnetization of the host rocks) enveloping the four anomalies and demonstrating a major alteration cell
indicative of a significant epithermal system.
Resistivity
A CSAMT survey was completed in February 2025 by the RUA GOLD team. CSAMT is particularly
effective at detecting ground resistivities to depths of several hundred meters, which can be interpreted
to represent strong silicification and quartz veining when directly related to an area of intense alteration.
The survey identified several major, deep structures that align with features previously identified by UAV
magnetics, gold-arsenic geochemistry anomalies, and mapped quartz veins, silicification and clay
alteration (Figure 3).

Glamorgan Exploration Overview
Following grant of a drone concessions in May 2024, and minimum impact exploration in July 2024,
RUA GOLD's exploration commenced with UAV ultra detailed magnetic surveying completing 590-line
kms of flying using Geometrics MagArrow magnetometer suspended under a DJI M300 drone.
Interpretation of the data has assisted in defining key aspects of lithology and alteration of the Whitianga
Group rhyolites, and Coromandel Group andesites. Major structural elements are interpreted in the data
aligning with regional mineralization trends.
Soil sampling commenced in July 2024 sampling along 250m spaced crosslines with a sample spacing
of 20m. 3181 samples were collected, dried, sieved in RUA GOLD's Waihi facility, then transported to
Reefton for pXRF analysis. Each sample was also scanned using a TerraSpec 4 Hi-Res mineral
analyzer to complete a picture of clay/alteration system enabling identification of the higher levels of the
epithermal system. 50gms of soil was then freighted to ALS Brisbane for low-level precision gold assay.
Arsenic anomalism with coincident gold anomalism highlights the four major soil anomalies A-D (Figure
2).
Anomaly A trends North north-west for 4.2 kms with conjugate gold-arsenic trends in a north-east
direction. This anomaly remains open to the northeast. This north-east direction mirrors the orientation of
the significant Wharekirauponga gold deposit 3 kms southeast of the Glamorgan permit.
Anomaly B trends northerly and follows north to northeasterly quartz veins mapped over 4 kms and open
to the north and south. The southern end of this anomaly coincides with the Wentworth/Auckland
historical mine workings.
Ultra detailed UAV magnetics flown by the RUA GOLD team highlights strong alteration (de-
magnetization of the host rocks) enveloping the two anomalies and demonstrating a major alteration cell
indicative of the footprint of a major epithermal system.
Field mapping (ongoing) has highlighted broad alteration and veining in situ, and areas of quartz-
adularia float displaying banded, platy quartz after calcite, and brecciated andesite with stockwork
veining increasing toward the zones of interest. Rock sampling both float and in situ sampling has
returned encouragingly anomalous gold (refer to Table 2 in the appendix below), coincident with the
zones of high soil geochemistry.

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
geophysical, sampling, and mapping programs to verify that they have been conducted in accordance
with the 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 SOIL SAMPLES
A bulk sample of ~0.5-1 kg was collected in the field. 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 Waihi facility for preparation. 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 50-100g was scooped from the <180 µm
size fraction for analysis. The remaining material was retained and stored in Waihi.
The 50-100-g fine-sieved (<180µm) soil sub-sample was sent to RUA GOLD's Reefton facility for pXRF
using an Olympus Vanta hand-held analyser, and then on to ALS Geochemistry, Brisbane, for Au-TL43
analysis. The ALS analysis consisted of 25-g sample digestion by aqua regia, followed by trace Au
analysis by ICP-MS. The detection limit for Au by this method is 1ppb. ALS Brisbane is independent to
RUA GOLD.
Field duplicates were collected every 20
th
sample and underwent the same drying, sieving, pXRF, and
gold assay process outlined above. Duplicates were checked and validated by RUA GOLD's Isogonal
data validation system to ensure compliance.
QA/QC ROCK-CHIP SAMPLES
Rock-chip samples were collected in the field during routine mapping and soil sampling. The location of
each sample was recorded in the field with a Garmin GPSMAP 66i and details of the samples recorded
in a notebook or mapping application. Samples were photographed and sent to SGS Waihi for sample
preparation. Sample information was entered into .csv files and uploaded to an SQL database.
Samples were crushed to 75% passing 2 mm (SGS code CRU75) and pulverised to 85% passing 75
µm (SGS code PUL85_CR). The pulverised rock-chips were split into two samples: a ~50 g sent for
laboratory analysis, and the reject returned to RUA GOLD for pXRF analysis and storage.
The 50 g sub-samples were analysed by AAS after fire assay at SGS Waihi (SGS code FAA505).
Detection values for this method are 0.01-100 ppm Au.
SGS is independent to RUA GOLD and its laboratories are accredited to applicable ISO/IEC 17025
standards.
