McFarlane Lake Mining Limited is focused on advancing its flagship Juby Gold Project, located near Gowganda, Ontario, within the established Abitibi Greenstone Belt. The Juby Project hosts a current (effective September 29, 2025) NI 43-101 compliant Mineral Resource Estimate (MRE) of 1.01 million ounces of gold in the Indicated category at an average grade of 0.98 g/t gold (31.74 million tonnes) and an additional 3.17 million ounces of gold in the Inferred category at an average grade of 0.89 g/t gold (109.48 million tonnes). The estimate was calculated using a long-term gold price of US$2,500 per ounce, applying cut-off grades of 0.25 g/t gold for open pit and 1.85 g/t gold for underground resources.

Table 1

A sensitivity analysis completed at a higher gold price of US$3,750 per ounce resulted in an Indicated Mineral Resource of 1.20 million ounces grading 0.94 g/t gold (39.51 million tonnes) and an Inferred Mineral Resource of 4.23 million ounces grading 0.85 g/t gold (154.50 million tonnes) applying cut-off grades of 0.25 g/t gold for open pit and 1.15 g/t gold for underground resources.

McFarlane is actively planning an exploration drilling program and additional technical studies at the Juby Project to further evaluate and advance this large-scale gold system.

The properties are located within Northeastern Ontario, approximately 13 km south of Espanola and 70 km southwest of Sudbury.

The McMillan Property is comprised of 12 mining leases totaling 268 hectares. The Mongowin Property is comprised of 122 mining and 3 patented claims, totaling 2605 hectares. McFarlane Lake acquired 1 claim by staking April 2022.

Gold associated with extensive albitization developed along fault systems – linked to timing of 1700 +/- 2 Ma alkalic magmatism.

Multiple high grade gold occurrences focused along E-W trending House Lake and NE trending Fox Lake fault systems. Extensions of McMillan mine mineralization open at depth and along strike.

McMillan Historical Mining Operation

• McMillan is 1 of 3 historical gold producers of >10,000 oz in the region
  1. McMillan Mine ~10 koz gold
  2. Scadding Mine ~30 koz gold
  3. Long Lake ~ 55 koz gold
• The largest historical mining operation in the 28 km Huronian Gold Belt trend

The property has been explored since 1910, initially with test pitting, followed by shaft and level development commencing in 1927. The shaft reached a depth of 900 feet with development being completed on 7 levels.

Mine production as reported between 1934 and 1937 amounted to approximately 10,591 ounces of gold from 60,139 tons of ore for a recovered grade of 0.176 oz/ton.

Geophysics

Original VLF survey completed by Ingmar Explorations Limited 1985.

Data was re-processed by Superior Exploration using proprietary software.

 A number of high priority targets were identified for ground follow-up and drilling.

Of particular note is anomaly C displaying a continuing of the mine trend to the east beyond current drilling and a strengthening of the anomaly with depth.

McMillan Mine Significant Gold Intercepts

McMillan Future Work

• Focusing on the McMillan Mine with historic mine infrastructure and year-round access
• Property covers 9 km of the 28 km Huronian gold belt
• 6 historic workings and multiple gold occurrences, samples of up to 10.9 gpt gold
• McMillan is Magnetic! Magnetic anomalies may represent more mineralization. Excellent tool to discover more mineralization

                                   Michaud – Numerous historic shallow gold intersects. Approximately 4000m drilled since 1955,                                                                       last drilled in 1995. Two well-known major fault systems to South and North of property                                                                                     (Destor-porcupine and pipestone faults). Property was family held for 50+ years until recently

                                   Munro – Munro property is part of the prolific Kidd-Munro Lithostratigraphic assemblage within                                                                       the Abitibi Greenstone belt. Ultramafic and Mafic Vocanic rocks which hosted 4 VMS producing                                                                       mines, Kidd Creek mine 80km to the east and Potter, Potterdoal and Hedman mines to the                                                                                 immediate north and south of the property.
