FINLAY MINERAL'S ATTY 2025 EXPLORATION PROGRAM DELIVERS EXPANDED AND MULTIPLE NEW TARGETS

Finlay Minerals Ltd.'s 2025 Atty exploration program has expanded known targets and identified further new copper and gold porphyry targets. The Atty project is strategically centred within a major porphyry corridor in the Toodoggone district and is under an earn-in agreement with Freeport-McMoRan Mineral Properties Canada Inc.

Highlights from the 2025 Atty exploration program include:

• Expanding the Wrich Cu-Au porphyry target to a 1,200-metre-by-1,200-metre area;
• Discovering the new Wrich Hill Au target;
• Discovering the new Pyramid West and Pyramid East Cu-Au porphyry targets;
• Further extending the Valley chargeability target by 500 metres to the southeast;
• Adding geological and geophysical definition to the porphyry corridor targets within the Atty property.

Ilona B. Lindsay, Finlay's president and chief executive officer, stated: "We are very pleased with the results of our 2025 Atty program and are moving forward with planning for 2026. The expansion of our known targets, along with the discovery of multiple new targets, has reinforced Atty's significant position between Freeport-Amarc's Joy property with its AuRORA discovery and Centerra Gold's expanding Kemess project. Through a systematic exploration approach, supported by Freeport's funding, Finlay is effectively demonstrating the substantial value of its property portfolio."

Detailed overview of 2025 exploration program targets

Northwestern porphyry trend and target areas

The 2025 exploration program expanded on previous work outlining an 8.5-kilometre northwestern porphyry trend, which includes the Wrich, Pyramid and Kem/Attycelley targets. Similar mineralized trends are found at nearby AuRORA, Pil South and Kemess projects. Soil sampling, geological mapping, geophysics and historical data have established targets at the Atty, all of which show strong exploration potential.

Wrich Cu-Au porphyry target

The Wrich Cu-Au porphyry target has strong soil anomalies in copper, gold, silver, molybdenum, selenium and tellurium, a high induced polarization chargeability, and is closely linked to Takla group volcanic rocks, which are favourable for Cu-Au porphyries like the Kemess deposits. Two thousand twenty-two drilling at SWT confirmed anomalous gold and copper zones near a porphyry system; notably, hole JP22028 intersected 78 metres at 0.09 per cent copper equivalent (0.02 per cent Cu, 0.11 gram per tonne Au and 0.04 g/t silver).

Wrich Hill target

The Wrich Hill target is a newly identified geochemical anomaly (1,200 m by 600 m) with elevated gold, bismuth, lead, tellurium and zinc in soil samples. Linked to a magnetic low, it may indicate a low- and high-sulphidation environment noted to be related to porphyry targets. North of Wrich Hill, drilling on the Joy property in 2022 found Au-Ag-Cu mineralization, including 108 metres at 0.03 per cent Cu, 0.23 g/t Au and and 6.4 g/t Ag in hole JP22044 within advanced argillic alteration zones.

Pyramid Cu-Au porphyry target

The Pyramid copper-gold porphyry target consists of two areas:

• Pyramid West: contains a 200-metre-by-200-metre copper-gold-molybdenum-tellurium soil anomaly open to the north, with a single IP line showing a 500-metre chargeability high, cut off by a southern fault; the anomaly extends east with a weaker response; the area is mainly underlain by Toodoggone Hazelton formations, similar to AuRORA and Kemess East;
• Pyramid East: features a continuous IP chargeability high potentially linked to the Wrich target, trending southeast toward an 800-metre-by-850-metre copper-gold geochemical anomaly and a circular magnetic feature; this anomaly lies just south of the Awesome epithermal gold showing, in propylitic-altered Takla volcanic rocks.

Valley target

The 2025 program expanded an already significant IP chargeability anomaly by 500 metres to the southeast, bringing it to a 1.5-kilometre width and a 1.8-kilometre length. Earlier drilling conducted in 2019 revealed anomalous copper in propylitic- and phyllic-altered Takla group rocks, suggesting potential proximity to a porphyry system.

Kem and Attycelley targets

Geological mapping at the Kem copper-gold porphyry target has improved its prospects for discovery. Recent quartz vein samples near the Kem mineral yielded up to 0.685 per cent copper, 0.135 g/t gold and 99.2 g/t silver. The Kem area spans 1,000 m by 2,200 m with high chargeability, forming part of a larger 3,000-metre-by-3,000-metre copper-gold-silver geochemical anomaly that also includes the Attycelley target. Both sites exhibit IP and geological traits similar to the Kemess North trend, which hosts significant deposits. Previous drilling at Kem was limited by inadequate depth and postmineral intrusions.

The 2025 exploration program completed on the Atty consisted of:

• 543 line km of airborne magnetics;
• 152 rock samples collected;
• 647 soil and talus samples collected;
• 14 line km of IP.

Both the Atty and Pil exploration programs are fully financed through earn-in agreements with Freeport. Under these agreements, Freeport can earn an up-to-80-per-cent interest in each property by financing a total of $35-million in exploration expenditures and making cash payments of $4.1-million over a six-year period, Finlay will serve as the operator for both projects and will earn an operator's fee.

Quality control/quality assurance program

Soil samples were sent to the ALS Canada Ltd., North Vancouver, Canada, facility for preparation and analysis. At ALS, soil samples were dried at 60 C and sieved to minus 180 micrometres (minus 80 mesh). The minus 80 mesh fraction for all samples was analyzed for Au at ALS by fire assay fusion of a 30-gram subsample with an ICP-AES finish. Samples were further analyzed for 48 elements using four-acid supertrace analysis (ME-MS61).

Rock samples were crushed to 70 per cent passing less-than-two-millimetre size, mechanically split (riffle split) with a representative sample being pulverized to 85 per cent passing less than 75 mum. Samples were then analyzed for Au at ALS by fire assay fusion of a 30-gram subsample with an ICP-AES finish. Samples were further analyzed for 48 elements using four-acid supertrace analysis (ME-MS61). ALS is ISO/IEC 17025 accredited.

As part of a comprehensive quality assurance/quality control program, Finlay control samples were inserted in each soil sample analytical batch at the rate of one standard and/or blank in 25 regular samples. The control sample results were then checked to ensure proper QA/QC.
