Key Projects
Stars Project
The Stars project is a 9,694-hectare, road-accessible copper-molybdenum property situated within the prolific Bulkley porphyry belt. The district is home to past-producing operations such as the Huckleberry mine, operated by Imperial Metals, and Newmont’s Equity Silver Mine, making it a proven copper jurisdiction. Stars is defined by a 5 × 2.5-kilometre annular magnetic anomaly that coincides with a copper-molybdenum mineralized monzonite intrusion. In 2018, drilling confirmed a significant porphyry system at the Tana Zone, returning intercepts of 0.466 percent copper over 195.1 m from 23 m with molybdenum credits and 0.20 percent copper over 396.7 metres from 28 metres depth. Shorter, higher-grade sections included 40 metres averaging close to 1 percent copper. Importantly, every hole drilled on the property has returned copper concentrations well above background levels, with strong phyllic and potassic alteration, multi-phase intrusive textures, and quartz-sulfide veining consistent with productive porphyry systems.
Impressive drill results in 2018 have never seen follow-up exploration
Geological comparisons with Huckleberry suggest Stars has the potential to host multiple deposits along more than 30 kilometres of untested intrusive contact. Upcoming work will focus on IP surveys to vector into contact zones, step-out drilling at the Tana Zone, and initial drilling of embayment features such as the “Big Dipper” anomaly.
Rip Project
The Rip project is a 4,750-hectare copper-molybdenum property located 60 kilometres south of Houston, BC, with excellent access via Highway 16 and logging roads. Geophysical surveys completed in 2024, including airborne magnetics and a 3D-DCIP induced polarization program, identified two concentric chargeability anomalies encircling separate magnetic highs. These “donut” features are classic pyrite halos that typically rim porphyry copper centres.
In late 2024, Copper Quest drilled two holes totaling 1,033 metres into the northern anomaly. The results confirmed the presence of multi-phase porphyry intrusions with abundant quartz-pyrite-chalcopyrite-molybdenite veining, long intervals of anomalous copper above 0.1 percent, and strong alteration patterns. The larger southern anomaly remains completely untested and represents the project’s most significant target. Copper Quest has the option to earn up to 80 percent in Rip by spending $1 million by the end of 2025, after which the agreement transitions to a joint venture. Planned drilling will test the southern anomaly while stepping out on the northern target to vector into higher-grade zones.
Stellar Project
The Stellar project covers 5,389 hectares and lies immediately north of Stars. It consolidates multiple historic claims and showings that had never been evaluated under a unified geological model. Stellar hosts several key targets, most notably the Cassiopeia anomaly, a 2.5-kilometre magnetic bullseye with an 800-metre magnetic low at its centre, discovered in 2019 but never drill tested. This geophysical feature is strongly consistent with porphyry copper-molybdenum-gold models.
The Jewelry Box area is another high-priority target, hosting eight documented MINFILE showings where historical sampling returned extreme grades, including 36.7 percent copper, 31.2 percent copper, 22.6 percent copper with 4,860 grams per ton (g/t0 silver, and gold values up to 42 g/t. These occurrences are related to a porphyritic intrusion that cuts Hazelton Group volcanic rocks and limestone, with mineralization styles ranging from high-grade copper-gold-silver veins to lead-zinc-silver occurrences and rhodonite-hosted mineralization. Additional targets include the Galena Zone, a 100 × 150 metre area with strong lead-silver-zinc mineralization, and the Northwest Showings, associated with syenite intrusions. Copper Quest is applying a holistic approach to the property for the first time, integrating fragmented historical exploration. Planned programs include ground IP at Cassiopeia, systematic mapping and sampling at Jewelry Box, and drill targeting across the consolidated property.
Thane Project
The Thane project is a 20,658-hectare copper-gold property in the Toodoggone District of the Quesnel Terrane, an area that hosts major porphyry deposits such as Mt. Milligan and Kemess. The property encompasses a 14 km × 6 km alteration footprint with at least ten mineralized centres, including Cirque, Fairway, Bananas, Gail, and Aten. Historical exploration has involved more than $5 million of investment in mapping, geochemistry, geophysics and shallow drilling, with 12 short diamond drill holes completed to date. Rock sampling campaigns between 2013 and 2020 returned copper grades exceeding 9,000 parts per million (ppm) and gold values up to 12.8 g/t, highlighting the system’s fertility. Regional Geoscience BC datasets place Thane in the 100th percentile for copper prospectivity across British Columbia. Copper Quest views Thane as a large-scale discovery opportunity and is considering a joint venture to advance the project while retaining upside exposure.
Nekash Project
The Nekash project is a highly prospective copper-gold porphyry opportunity in Lemhi County, Idaho, situated along the prolific Idaho-Montana porphyry belt. Spanning 70 unpatented federal lode claims (~585 hectares), the property is fully road-accessible via maintained US highways and forest service roads. Historic sampling has confirmed the presence of high-grade surface mineralization, including up to 3.8 percent copper, 0.9 g/t gold, and 25 g/t silver over 6.4 m in a stratabound “manto” horizon, and porphyry-style veins grading as high as 6.6 percent copper with gold values.
Acquired at a modest cost (4.25 million shares, no cash payment or royalties), and coupled with the appointment of an experienced technical advisor, Nekash offers shareholders exposure to a jurisdiction with favorable infrastructure, strong comparables and room for significant upside through geophysics, geochemistry and drilling.

Copper Prices Up as Freeport-McMoRan Announces Force Majeure at Grasberg
It is expected that the investigation will be completed by the end of 2025.
Due to the mine's closure, Freeport has adjusted its guidance, reporting that third quarter consolidated sales will be 4 percent lower for copper and 6 percent lower for gold compared to its July estimates.
Furthermore, Grasberg's closure means sales from the mine during the fourth quarter will be insignificant; the company previously forecast the sale of 445 million pounds of copper and 345,000 ounces of gold.
The Grasberg site encompasses several underground mines: the Grasberg block cave, the Deep Mill Level Zone (DMLZ) and Big Gossan. DMLZ and Big Gossan were not affected, and could restart production in the fourth quarter.
However, according to Freeport-McMoRan, a preliminary assessment indicates a delayed restart of operations at the Grasberg block cave, resulting in the deferral of significant production in the near term. A ramp up in this area is not anticipated to begin until the first half of 2026, with the mine potentially returning to full production in 2027.
Grasberg is one of the world’s largest copper and gold mines, producing 1.7 billion pounds of copper and 1.4 million ounces of gold annually. Freeport holds a 49 percent interest, with the Indonesian government owning the rest.
The announcement caused copper prices to spike nearly 5 percent in trading on Wednesday, climbing to US$4.84 per pound on the COMEX and US$9,900 per metric ton on the London Metal Exchange.
Freeport’s share price tumbled 16.95 percent in trading, closing the session at US$37.67 after opening at US$41.66.

Nine Mile samples up to 18.27% Cu at Wedge
As previously reported, the Cominco drill data were acquired by Nine Mile and formatted to facilitate modelling. With the addition of Mike Dufresne, MSc, PGeol, PGeo, of Apex Geoscience Ltd. to the technical advisory committee, the company provided the technical database to Apex for 3-D modelling and drill hole targeting. Data provided included all historic drill holes and assays in addition to the recent successful drilling conducted by Nine Mile. To further assist in targeting, the UAV (unmanned aerial vehicle) magnetics and borehole electromagnetic (BHEM) data collected by EarthEx Geophysical Solutions Inc. was integrated into the modelling in addition to the initial, reprocessed MegaTEM conductivity interpretation that highlighted the Wedge and the Wedge VMS trend.
At the Wedge mine's western extension (Target 2), modelling has focused on the unmined portions of the deposit with drill holes targeting a copper-rich lens to the west and the unexplored depth extension below 150 metres, where recent drilling and historical cross-sections indicate mineralization occurring to a minimum depth of 300 metres. Apex is designing a sequence of drill holes to test the seven modelled TDEM (time-domain electromagnetic) conductivity plates adjacent to the Tribag VMS occurrence identified by EarthEx (Target 3).
In preparation for drilling, prospecting was conducted at surface in an area proximal to the proposed drill collars along the western flank of the Wedge mine stepping out to test the expansion westward of the mine footprint. A total of 19 samples were catalogued, photographed, and then analyzed with a portable X-ray fluorescence (XRF) instrument utilizing an Olympus Vanta 50 portable 50-kilovolt workstation and Reflex XRF software to provide instant real-time geochemical information. Each sample was analyzed in three separate locations and the results averaged by the Reflex XRF software. The XRF process included calibrating the machine and utilizing two standards in the sample stream (OREAS622 and CDN-BL-10) twice during analysis. The results are presented in Table 1. The samples have been forwarded to ALS Global in Moncton, N.B., for preparation, with final geochemical analysis conducted in Vancouver, B.C.
Highlights:
- Samples were massive VMS (copper-lead-zinc) mineralization collected at the coming Wedge drill area.
- The samples were weathered and predominantly copper rich with minor lead/zinc.
- Most samples consisted of 90 per cent plus sulphides and minor quartz and accessory minerals.
Samples 280370 and 280375 are examples of the massive high-grade cooper sulphide mineralization. The samples were collected in the area immediately to the northeast of proposed drill holes 25WG-01 and 25WD-02.

Mr. Dufresne, Apex's president and an independent consultant and technical adviser, commented that these high-quality conductivity targets at the Wedge mine's western extension and TriBag target line up with the horizons that have yielded high-quality VMS drill intersections at the Main Wedge deposit and, based upon the modelling to date, could provide some new exciting discoveries for Nine Mile with the planned drilling.
Gary Lohman, PGeo, vice-president, exploration, stated: "With the provincial-wide fire ban lifted and Apex Geoscience's 3-D modelling complete, the team is looking forward to drilling at the Wedge mine's western extension. With the assistance of Apex, two main zones of mineralization have been identified, one copper rich and another primarily lead/zinc. Targeting has been refined by leveraging the extensive geological and geophysical data (including recent borehole EM and plate modelling), allowing us to prioritize copper mineralization in the upcoming program. This western extension area is the high-grade section of the deposit focused on the copper-rich lens. These massive sulphide samples clearly demonstrate the potential of this untapped area at depth. We are building on last year's new eastern extension successes with our eight VMS drill holes with results of 136.31 metres of 0.68 per cent copper equivalent, including 40 metres of 2.03 per cent copper equivalent (see news release [dated March 26, 2024]). A key aspect here is testing this deposit at depth and how far it extends westward resulting in additional new tonnage."

About Empire Metals Limited
Empire Metals is an AIM-listed and OTCQX-traded exploration and resource development company (LON: EEE,OTCQX: EPMLF) with a primary focus on developing Pitfield, an emerging giant titanium project in Western Australia.
The high-grade titanium discovery at Pitfield is of unprecedented scale, with airborne surveys identifying a massive, coincident gravity and magnetics anomaly extending over 40km by 8km by 5km deep. Drill results have indicated excellent continuity in grades and consistency of the in-situ mineralised beds and confirm that the sandstone beds hold the higher-grade titanium dioxide (TiO₂) values within the interbedded succession of sandstones, siltstones and conglomerates. The Company is focused on two key prospects (Cosgrove and Thomas), which have been identified as having thick, high-grade, near-surface, in-situ bedded TiO₂ mineralisation, each being over 7km in strike length.
An Exploration Target* for Pitfield was declared in 2024, covering the Thomas and Cosgrove mineral prospects, and was estimated to contain between 26.4 to 32.2 billion tonnes with a grade range of 4.5 to 5.5% TiO2. Included within the total Exploration Target* is a subset that covers the in-situ weathered sandstone zone, which extends from surface to an average vertical depth of 30m to 40m and is estimated to contain between 4.0 to 4.9 billion tonnes with a grade range of 4.8 to 5.9% TiO2.
The Exploration Target* covers an area less than 20% of the overall mineral system at Pitfield which demonstrates the potential for significant further upside.
Empire is now accelerating the economic development of Pitfield, with a vision to produce a high-value titanium metal 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.
*The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. See RNS dated 12 June 2024 for full details.
