McFarlane Lake Mining Limited Reports Diamond Drilling Results At Juby Gold Project McFarlane Lake Mining Limited announced further results from its diamond drilling exploration campaign being conducted on its 100%-owned Juby Gold Project, located west of Gowganda, Ontario, within the southern part of the Abitibi Greenstone Belt. Drilling was initiated on the property in December 2025, commencing at 826 Zone, and is now at the Golden Lake Zone. The Golden Lake Deposit continues to grow by demonstrating scale and continuity of gold mineralization, extending the mineralized envelope south of and below the current resource pit shell. Drilling has now increased mineralization on the western side of the deposit, confirming a broader and more continuous gold-bearing system than previously defined. Additional wide intercepts expand mineralization to the west: Hole GL26-84 intersected 155 m of 0.59 g/t Gold, including 75.8 metres of 0.70 g/t Au, that includes 3.0 m of 1.91 g/t Au and 3.5 m of 1.80 g/t Au. Hole GL26-85 intersected 92.7 m of 0.64 g/t Au, including 4.8 m of 3.37 g/t Au and 9.0 m of 1.58 g/t Au. Continuity confirmed between prior holes: Hole GL26-77B, drilled between previously reported holes GL26-76 and GL26-78, returned 47.0 m of 0.70 g/t Au, including 13.1 m of 1.92 g/t Au, strengthening confidence in the continuity of mineralization. Multiple catalysts remain pending: Additional holes at Golden Lake have been completed and are awaiting assays, while follow-up drilling has resumed at the 826 Zone after encouraging initial results. McFarlane has recently made presentations to all three First Nation communities having territorial rights in the area. Presentations focused on the environmental baseline study work being conducted, as well as the Company’s plans around the extraction of a 50,000-tonne bulk sample in 2027. Drilling being conducted at site is contracted through two separate firms, each having a business partnership with two of the three First Nation communities that have territorial rights on the property. There are three First Nation communities recognized as having territorial rights within the Juby Gold Project. They include Matachewan First Nation, Temagami First Nation and Atikameksheng Anishnawbek First Nation. The Company, in co-operation with its engineering consultant, BBA E&C Inc., is currently working to update its Mineral Resource Estimate. The Company is expecting to update resources at the Golden Lake deposit as well as the Juby deposit and is expecting to have new compliant resources at its developing 826 Zone. Management decided to add an additional drill hole at the Golden Lake Deposit and incorporate it into the updated Mineral Resource Estimate. The additional drill hole will push back the release of the Mineral Resource Estimate by about 2 weeks, so a new Mineral Resource Estimate is expected within the next 3 to 4 weeks. The Juby Gold Project hosts a current (effective September 29, 2025) NI 43-101 compliant Mineral Resource Estimate 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 USD 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. A sensitivity analysis completed at a higher gold price of USD 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. The independent Mineral Resource Estimate was prepared by BBA E&C Inc. in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The drill core samples collected by McFarlane and described in this news release were placed in core boxes by the drill crew contracted by the Company. Core was then transported by McFarlane personnel to a secure processing facility. The core is then reviewed with core metreage blocks checked to verify core integrity, geologically logged, and samples marked. Core samples are cut in half, with one half remaining in the box and the other inserted into a clean plastic bag with a sample tag. Certified reference materials are inserted into the sample stream at a rate of no less than 10%. Samples are then transported in secure sealed bags with security tags for preparation and assay by MSA Labs in Timmins, Ontario, a certified lab with AC89, IAS accreditation and compliance with ISO/IEC standard 17025:2017. Samples reported are crushed at the lab in their entirety to 70% passing 2 mm, with one 300 to 500 g subsample split and placed into a jar for analysis by photon assay. Gold concentration results are then recorded with reference to each sample tag number. Announcement • Jun 06
