McFarlane intersects 179 metres (m) of 0.87 grams/tonne (g/t) Gold and 155 m of 0.9 g/t Gold
Overall Strike length now extends to 1.9 kilometers (km)
New mineralized lense discovered in “Hanging Wall” widens gold mineralization in Golden Lake Deposit at Juby Gold Project
More mineralization intersected at 826 Zone
TORONTO, July 23, 2026 (GLOBE NEWSWIRE) -- McFarlane Lake Mining Limited (“McFarlane” or the “Company”) (CSE: MLM, OTC: MLMLF, FRA: W2Z) is pleased to announce 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 the 826 Zone, and is now at the Golden Lake Zone (see Figure 1).
Highlights
Golden Lake Deposit continues to show excellent potential to add significant gold mineralization. From recent exploration drilling the strike length of gold mineralization has now extended to 1.9 kilometers in length from a previously announced 0.75 km (See Figure 2). Further holes GL26-83 and GL26-83A demonstrate a widening of the mineralization from the existing open pit shell (see Figure 3), this not only increases revenue potential but also favourably affects the economics of extraction.
Most Western drilled hole extends strike to 1.9 km: Assays from hole GL26-87 (93 m of 0.89 g/t gold) have confirmed a significant intersection on the most western hole drilled in the program on the Golden Lake deposit. This intersection not only extends the strike length to 1.9 km but demonstrates the deposit remains open to the west and at depth in this area.
New Mineralized Lense widens open pit outline in “Hanging Wall”: Commencing at 34 m from surfaces Hole GL- 83A intersected 179.10 m of 0.87 g/t gold which includes 15.55m of 1.58 g/t gold and 6.9 m of 2.33 g/t gold. Commencing at 65.85 m from surface Hole GL-83 intersected 155 m of 0.9 g/t gold which includes 11.4 m of 2.37 g/t gold. Both holes intersected gold mineralization close to surface and about 250 meters before its targeted mineralized area. Mineralization in the hanging wall area of the pit outline was unexpected and but now creates an opportunity to step back and test the extension (widening) in this area.
New Multiple mineralization intercepts at 826 zone: Mcfarlane has recently drilled 8 new holes on the 826 zone covering an additional 1350 m. Full assays are expected on the drilling in the coming weeks. Geologists have reported in the core logs that several intercepts of mineralization were encountered. These intercepts follow previous trends of mineralization seen from past drilling and widen the mineralization “dome” that was reported in detail on March 2, 2026 announcement. Drilling was targeting geophysical chargeability anomalies that follow an southeast/northwest trend and which are detailed in a previous announcement (May 26, 2026). McFarlane is currently engaged with Geoscience North who has teamed up with support from Laurentian University to analyze past geophysical data on the property and propose next steps.
Mark Trevisiol, McFarlane’s CEO, commented, “Both Golden Lake and 826 zone continue to impress. We are looking forward to updating the MRE and demonstrate to our stakeholders how extensive the gold system on our property is. We believe we are just ‘scratching the surface’ on this property with significant upside to add significantly more gold mineralization.”
Drilling at site continues on both Golden Lake and the Juby deposit. Drilling on Golden Lake will concentrate both on infill and some exploratory drilling. On the Juby deposit drilling will focus on grade control sampling for the upcoming Bulk Sample which is planned in 2027.
All the drilling for the upcoming Mineral Resource Estimate (MRE) concluded at the end of June. There was an unplanned 10 day delay in receiving assays due to equipment failure at the assay lab, however, as of todays’ announcement, all assays for the upcoming MRE have been received. McFarlane now expects the MRE to be issued in the next 2 to 3 weeks.
McFarlane is also continuing with Environmental Baseline work on the property. Approximately 19 ground water wells have now been drilled with monthly surface and ground water sampling continuing. Field studies have commenced for vegetation and terrestrial analysis. Environmental Baseline work has been reviewed with all three First Nation communities who have territorial rights in the area. 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.

Quality Assurance and Quality Control
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.
About McFarlane Lake Mining Limited
McFarlane Lake Mining Limited is a Canadian gold exploration company focused on advancing its flagship Juby Gold Project, located near Gowganda, Ontario, within the established Abitibi Greenstone Belt. The Juby Gold 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.
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.
The independent MRE was prepared by BBA E&C Inc. in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The full technical report supporting the resource estimate was filed on SEDAR+ on November 21, 2025. The technical report is also available on the Company’s website www.mcfarlanelakemining.com.

Cautionary Statement on Mineral Resources
This news release uses the terms indicated and inferred mineral resources as a relative measure of the level of confidence in the resource estimate. Readers are cautioned that mineral resources are not mineral reserves and that the economic viability of resources that are not mineral reserves has not been demonstrated. The mineral resource estimates disclosed in this news release may be materially affected by geology, environmental, permitting, legal, title, socio-political, marketing or other relevant issues. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to an indicated or measured mineral resource category; however, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. The mineral resource estimate is classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum’s “CIM Definition Standards on Mineral Resources and Mineral Reserves” incorporated by reference into NI 43-101. Under NI 43-101, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies or economic studies except for preliminary economic assessments. Readers are cautioned not to assume that further work on the stated resources will lead to mineral reserves that can be mined economically.
