Galway Metals Confirms Improved Au and Sb Recovery with Process
Optimization
(Toronto, Ontario, May 14, 2025) – Galway Metals Inc. (TSX-V: GWM); OTCQB: GAYMF) (the
“Company” or “Galway”) is pleased to report improved gold recovery, and the capture of antimony as
a potential bi-product following the recent completion of Q1 2025 test work on diamond drill hole
samples from the Southwest, South and North Deposits at the Company’s 100%-owned flagship
Clarence Stream high-grade gold project in New Brunswick, Canada.
The Clarence Stream Gold Project has district-scale potential with approximately 65-kilometre strike
length of highly prospective gold showings and anomalies; and a 2022 MRE of 12.4 Mt @ 2.3 g/t Au
Indicated for 922,000 M ozs Au, and 16.0 Mt @ 2.6 g/t Au Inferred for 1.334 M ozs Au (at $1650 Au
price) from the NI 43-101 technical report titled “Technical Report on the Clarence Stream Mineral
Resource Project, New Brunswick, Canada” dated March 31, 2022, by SLR Consulting Ltd.
Rob Hinchcliffe, President and CEO of Galway Metals, commented, “We’re very encouraged by the
strong gold recoveries from both low -grade and high -grade antimony mineralization at Clarence
Stream, demonstrating the robustness of our new processing strategy. Working with Steve Haggarty,
in just under a year we’ve made great progress advancing our hybrid flowsheet. These results highlight
the potential to c apture additional value from antimony. With two rigs drilling, we’re focused on
expanding high-quality gold ounces and improving metallurgical recoveries. Together, these efforts are
building a stronger foundation to support future economic assessments of Clarence Stream.”
Metallurgical Highlights
• Gold extraction of 89–95% achieved in samples with low antimony content (<100 ppm Sb) via
direct cyanidation
• Gold extraction of 85–94% realized in high-antimony mineralization (up to 5% Sb) using hybrid
cyanidation-flotation process
• Antimony recoveries of 55–85% achieved to a gold-antimony flotation concentrate suitable for
off-site processing
Studies to Improve Overall Gold Recovery and Target Antimony Recovery
Recent test work evaluated a novel hybrid process configuration that is applicable to all material types
within the deposit over a range in Au, Sb and sulfide content. Realized Au recoveries varied from 85 to
94% Au recovery in the presence of elevated antimony content up to 5%, with an associated 55 to 85%
recovery of antimony.
This is particularly significant given Clarence Stream hosts over 25 million pounds of antimony (2022
MRE), and recent Chinese export restrictions have driven antimony prices up from roughly US$5 per

pound to about US$15 per pound, underscoring the value of capturing this strategic by-product.
The process strategy maximizes Au recovery to doré bullion, with an ability to recover antimony to an
Au-Sb concentrate for secondary processing. Associated test work was pursued by Galway Metals,
involving Haggarty Technical Services (Burlington, Ontario), and was completed at SGS-Lakefield.
Process Metallurgy Optimization
The amenability of Clarence Stream mineralization to cyanidation has been confirmed with 89-95% Au
extraction from material containing less than 100 ppm Sb at a grind size of 80% passing 75 µm. An
estimated 75% of mineralization present in the deposit is assoc iated with trace levels of Sb and is
expected to yield relatively high Au recovery.
The passivating influence of antimony on gold cyanidation is well known in the mining industry at
antimony levels greater than 100 ppm Sb. The hybrid process scheme provides the flexibility required
to pursue the recovery of soluble Au values in cyanidation, followed by cyanide destruction and the
flotation of remnant values to a low tonnage gold-antimony concentrate for secondary processing.
Secondary treatment of the gold-antimony concentrate is often pursued with off -site smelting.
Alternatives for the C larence Stream project could consider on -site, low pressure, low temperature
alkaline sulfide leaching to yield incremental Au recovery to doré bullion, and a marketable crystalline
sodium antimonate biproduct. As a technology, alkaline sulfide leaching has been successfully applied
on an industrial scale since 1942 treating similar concentrates.
Depicted in the simplified process schematic, the hybrid process involves conventional technology, with
a focus on maximizing Au recovery to doré bullion, while enabling the potential for bi-product recovery
of Sb values from secondary treatment of an Au-Sb concentrate.
Additional test work is in progress by Galway Metals over a range in Sb head grade to confirm the
potential upside and incremental Au and Sb recovery that could be expected from the hybrid process
strategy which will benefit project financials.

Geology and Mineralization
The Clarence Stream deposits can be characterized as intrusion-related, structurally controlled, quartz-
vein hosted gold deposits. These deposits consist of quartz veins and quartz stockwork within brittle-
ductile fault zones that include adjacent crushed, altered wall rocks and veinlet material. The

mineralized systems are hosted in intrusive and metasedimentary rocks within high strain zones
controlled by regional fault systems. Pyrite, base metal sulphides, and stibnite occur in these deposits
along with anomalous concentrations of bismuth, arsenic, antimony and tungsten. Alteration in the host
rocks is confined within a few metres of quartz veins and occurs mainly in the form of sericitization and
chloritization. A more complete description of Clarence Stream’s geology and mineralization can be

New Brunswick Junior Mining Assistance Program
Galway would like to acknowledge financial support from the New Brunswick Junior Mining Assistance
Program, which will contribute up to $50,000 towards exploration drilling in 2024.
