About Empire Metals Limited
Empire Metals Ltd (AIM: EEE and OTCQX: EPMLF) is an exploration and resource development company focused on the rapid commercialisation of the Pitfield Titanium Project, located in Western Australia. The titanium discovery at Pitfield is of unprecedented scale and hosts one of the largest and highest-grade titanium resources reported globally, with a Mineral Resource Estimate (MRE) totalling 2.2 billion tonnes grading 5.1% TiO₂ for 113 million tonnes of contained TiO₂.

The MRE, which covers only the Thomas and Cosgrove deposits, includes a weathered zone resource of 1.26 billion tonnes at 5.2% TiO₂ and a significant Indicated Resource of 697 million tonnes at 5.3% TiO₂, predominantly from the Thomas deposit. Titanium mineralisation at Pitfield occurs from surface and displays exceptional grade continuity along strike and down dip. The MRE extends across just 20% of the known mineralised footprint, providing substantial potential for further resource expansion.

Conventional processing has already produced a high-purity product grading 99.25% TiO₂, suitable for titanium sponge metal or pigment feedstock. The friable, in-situ weathered zone supports low-cost, strip mining without the need for blasting or overburden removal.

With excellent logistics and established infrastructure, including rail links to deep-water ports with direct access to Asia, the USA, Europe and Saudi Arabia, Pitfield is strategically positioned to supply the growing global demand for titanium and other critical minerals.

Empire is now accelerating the economic development of Pitfield, with a vision to produce a high-value titanium metal and/or pigment quality product at Pitfield, to realise the full value potential of this exceptional deposit.

The Company also has two further exploration projects in Australia; the Eclipse Project and the Walton Project in Western Australia, in addition to three precious metals projects located in a historically high-grade gold producing region of Austria.

Copper Quest Exploration Inc. (CSE: CQX,OTC:IMIMF; OTCQB: IMIMF; FRA: 3MX) (‘ Copper Quest ‘ or the ‘ Company ‘) is pleased to announce it has entered into a strategic partnership with U.S. based Exploration Technologies Inc. (‘ ExploreTech ‘) to deploy generative artificial intelligence across its project portfolio, beginning with the Kitimat Copper-Gold Project in British Columbia. The Company has also completed an initial work program at Kitimat and expanded its geological thesis based on historical datasets and updated field observations.

EXPLORETECH PARTNERSHIP OVERVIEW

ExploreTech integrates drilling, IP/magnetics, geochemistry, structural data, satellite imagery, and field observations into a unified 3D geological framework. The system generates thousands of subsurface model scenarios, evaluates probability, and optimizes drill plans for the highest-priority copper-gold targets. The technology has been successfully applied on multiple porphyry systems.

ExploreTech will collaborate with Copper Quest’s team on their portfolio of projects, with the Kitimat Copper-Gold Project being processed first.

ExploreTech will:

• Conduct AI-driven reprocessing and inversion of historical geophysical datasets
• Generate geological simulations to resolve concealed intrusive centers, alteration, and mineralization
• Produce probability-ranked target clusters
• Recommend optimized drillhole placement, orientations, and depths
• Integrate Copper Quest’s 2025 soil and rock geochemical data
• Provide a fully integrated drill targeting package for the Kitimat Project

The technology is ideally suited for covered porphyry systems such as Kitimat, where limited outcrop and shallow till cover obscure significant subsurface features.

KITIMAT WORK PROGRAM SUMMARY

Copper Quest engaged Hardline Exploration to complete a reconnaissance field program at Kitimat in November 2025, collecting soil and rock samples, documenting structural and lithological observations, and assessing access routes.

Field Highlights

• 24 soil samples collected along two soil lines (assays pending)
• Eight rock samples collected from outcrop and historical working exposures (assays pending)
• Bedrock consists of quartz monzonite
• Strong silicification
• 5–10% disseminated fine-grained pyrite
• Traces of chalcopyrite
• Local molybdenum
• Orange-rusty weathering, consistent with sulphide-rich alteration
• Access roads on the claims are intact
• Historical logging/exploration roads provide excellent future drill access

These observations are indicative of the presence of a large altered intrusive system consistent with a productive porphyry environment.

HISTORICAL DRILLING: CONFIRMATION OF A SIGNIFICANT CU-AU SYSTEM

Exploration at Kitimat dates to the late 1960s. The most significant work was completed by Decade Resources Ltd. in 2010, which drilled 16 diamond holes totaling 4,437.5 m at the Jeannette Cu-Au Zone.

Notable Drill Intervals (2010)

• Hole J-7: 117.07 m @ 1.03 g/t Au and 0.54% Cu (from 1.52 m to 118.60 m)
• Hole J-1: 103.65 m @ 1.00 g/t Au and 0.55% Cu (from 9.15 m to 112.80 m)
• Hole J-2: 107.01 m @ 0.80 g/t Au and 0.45% Cu (from 6.10 m to 113.11 m)
• Hole J-8: 112.20 m @ 0.41 g/t Au and 0.33% Cu (from 11.89 m to 124.09 m)
  (Kruchkowski, E., 2010, BC Assessment Report #31807)

Interpretation

• Long, continuous, near-surface copper-gold intervals
• Mineralization remains open at depth
• Geological indicators suggest the system extends laterally beyond the drilled area
• Vectoring from 2010 drilling trends northeast toward a concealed porphyry center
• No systematic follow-up drilling has been completed in 15 years

Copper Quest believes these results represent a strong opportunity for discovery within a larger, buried hydrothermal system.

2010 Drilling – Collar Location Data:

MANAGEMENT COMMENTS

Brian Thurston, CEO of Copper Quest

‘The Kitimat Project hosts excellent, historic mineralized intervals interpreted to represent a buried porphyry system. The long, near-surface copper-gold intercepts drilled in 2010 remain open and were never systematically followed up. ExploreTech’s AI platform will allow us to integrate decades of fragmented datasets and directly target the buried porphyry center that the geological evidence strongly supports.’

Alex Miltenberger, CEO of ExploreTech

‘Our generative AI technology evaluates thousands of geological and geophysical scenarios to identify the most probable mineralized centers. We look forward to supporting Copper Quest in unlocking the full potential of their portfolio of projects starting with the Kitimat Copper-Gold project.’

NEXT STEPS

1. Deliver all historical datasets to ExploreTech
2. Begin AI-driven modeling and geophysical inversion
3. Integrate 2025 soil and rock geochemical results
4. Receive probability-ranked target clusters and drillhole trajectories
5. Finalize the 2025–2026 exploration and drilling program
6. Assess applying ExploreTech’s technology to additional Copper Quest properties

Mineralization intersected in 8 of 9 holes at Tahami South, directly adjacent to Aris Mining’s producing operations in the Segovia gold district

Quimbaya Gold Inc. (CSE: QIM,OTC:QIMGF) (OTCQB: QIMGF) (FSE: K05) (‘Quimbaya’ or the ‘Company’) is pleased to announce the discovery of two new mineralized vein systems at its 100%-owned Tahami South Project in the Segovia-Remedios gold district of Antioquia, Colombia.

The Company’s ongoing drill program at Tahami South has successfully identified vein systems that include the previously targeted Vein S and Vein V, confirming the presence of mineralization consistent with quartz vein systems mined regionally. These results confirm the continuation of the Segovia district’s geological architecture onto Quimbaya’s ground, a core thesis of the Company’s strategy.

‘This is a milestone event for Quimbaya. These first vein discoveries validate our thesis and represent a turning point as we move from land assembly into value creation through the drill bit,’ said Alexandre P. Boivin, CEO of Quimbaya Gold. ‘They are not just promising results, they are proof that we’re on to a significant mineralized system, with the grades, geometry, and geology that define Colombia’s most productive gold district.’

Discovery Highlights

• Several Veins intersected across multiple drill platforms

• Mineralization intersected in 8 out of 9 drill holes, demonstrating strong structural continuity and robust targeting accuracy in the inaugural Phase 1 program.

• Drilling remains ongoing, with over 4,000 meters completed to date; the program has been extended beyond its initial scope in response to encouraging early results.

• Two distinct vein structures system (S & V) discovered, confirming Segovia-style mineral continuity on Quimbaya’s ground.

• Mineralization comprises quartz, barite, carbonate veining with sulphide assemblage (pyrite, chalcopyrite, galena, sphalerite).

‘These intercepts confirm that we are tapping into the same geological architecture that has made the Segovia district one of the most prolific gold producers in Latin America,’ said Ricardo Sierra, B.Sc., AusIMM, VP Exploration. ‘We see clear continuity in structure, mineralogy, grade, and believe we are only beginning to uncover the full potential at Tahami South.’

While initial assay results have been received from select drill holes, the Company is continuing to await the return of a significant portion of its Phase 1 drill campaign. In the interest of providing a more complete and technically coherent picture of the emerging discovery at Tahami South, Quimbaya intends to release assay data once a critical mass of results has been compiled. This approach ensures a balanced and contextualized interpretation of both grade distribution and structural continuity, and reflects the Company’s commitment to disciplined, data-driven disclosure as the scale of the system comes into focus.

Strategic Implications: Thesis Confirmed

The discovery of vein systems that include the previously targeted Veins S and V represents the first clear technical validation of Quimbaya’s exploration thesis: that district-scale mineralized structures extend beyond known mines into underexplored ground. The Company’s focused land acquisition strategy prioritized claims with gold & silver+ at surface and proximity to producers, and now, early drilling confirms this model is working.

With over 4,000 meters already drilled, surpassing the originally planned Phase 1 total, the Company has extended its current program to follow up on promising early results and to further evaluate vein continuity at depth and along strike. The strong correlation between drill intercepts and the geological model has reinforced Quimbaya’s exploration thesis. These results not only validate the presence of a robust mineralized system but also provide clear vectors for systematic expansion drilling in 2026.
