Exploration Extends Target Footprint at Ferber

Exploration Extends Target Footprint at Ferber Property, Nevada

Galileo Resources Plc ("Galileo") is pleased to report significant exploration progress at its' 100% owned Ferber Property ("the Property") under the terms of a Royalty and Exploration Agreement with Bronco Creek Exploration Inc. ("BCE"), a wholly-owned subsidiary of EMX Royalty Corporation ("EMX"). Mapping and rock sampling to date has extended the scale of the major intrusive and alteration complex indicating a large and strong hydrothermal system.

Highlights

· Significant mapping and sampling results to date as part of the Phase 1 Target Generation programme include:

o Multiple intrusive phases identified, suggesting potential for a substantial and complex mineralising system.

o 4 large fault blocks mapped extending the system to about 10km in an E-W direction.

o Western side of system with granodiorite not previously mapped in detail - intense sericitic alteration with skarns and visible copper oxide mineralisation (grab sample assay results awaited).

o Soil sampling programme complete - samples now with the laboratory.

o Gravity geophysical survey planned for Q3/early Q4.

· Previous grab sampling by Galileo at Ferber showed strong lead-zinc-silver signature as well as copper and gold.

· Analogies to Battle Mountain Trend deposits in Nevada (>100Mt Au in production and reserves + substantial copper and silver production), such as multiphase Eocene intrusives, skarn, alteration and copper-gold-silver mineralisation.

· Phase 2 of the BCE agreement incorporates a Reconnaissance Drilling programme to test priority targets generated by Phase 1.

· US administration support for fast-tracking of mine development within the country represents a boost for exploration/mining projects, including Ferber.

Colin Bird Chairman & CEO said: "I am very pleased to report that, following our announcement regarding commencement of work at Ferber, the Property is showing significant potential as was anticipated when we first acquired the claims from St Vincent Minerals in the US. Nevada is a fertile environment for copper and gold and we have identified geological similarities at Ferber with other producing mines in the district. Our geological thinking drives us towards a porphyry intrusive/skarn model - benefitting from the knowledge and experience of BCE personnel who are executing our field programmes at an operational level.

We strongly believe that the current investment climate and geopolitical drive for certain commodities in the US provides impetus not available in previous years. We are continuing our work with BCE to move the programme forward at pace, with the aim of delineating drill targets during Q4 2025. We are very encouraged by the results to date and look forward to updating shareholders as work progresses."

Ferber Project Background

The Property, located 40 kilometres south of Wendover in Elko County, Nevada, comprises a series of patented and unpatented claims covering an area of about 20 square kilometres.

The Ferber District consists of a multi-phase Eocene igneous complex intruding Pennsylvania-Permian age carbonates. The limestone units are domed around the intrusive. Marble and skarn are developed at the margin of the intrusive complex. The sedimentary and intrusive rock is cut by faults of various orientations. Polymetallic mineralisation occurs as contact skarn and replacement in limestone and the intrusive. Possible structurally controlled sediment hosted gold deposits are present, as well as a porphyry base metals/gold target.

Copper-lead-silver-gold deposits were discovered in the area in the 1880s. Ore was shipped from the Martha Washington, Big Chief, Regent and other small mines intermittently over the years. Limited production figures for the mines list 97,878 pounds copper, 192,613 pounds lead, 11,851 ounces silver. Cordex Exploration, Royal Gold and FMC Corporation have conducted exploration in the area since 1980s-1990s.

Numerous surface samples have been collected during historic exploration along with limited, mostly shallow, drilling. Reported drill intercepts include 2.37g/t Au over 4.6m and 0.59g/t Au over 10.7m as well as 0.83% Cu over 12.0m. Individual grab samples collected by Galileo from old workings and dumps have ranged up to 10.8g/t Au, 674g/t Ag, 4.19% Cu, 8.71% Pb and 7.62% Zn. In addition, assaying for a limited range of other elements has shown anomalous levels of bismuth and arsenic which are on the US list of critical minerals.
