McFarlane Intersects 9.20 Grams per Tonne Gold over 26.40 Metres - Intersection Includes 15.43 Grams per Tonne Gold over 4.60 Metres

Purdex Zone continues to deliver world-class gold intersections.

Toronto, Ontario--(Newsfile Corp. - March 6, 2023) - McFarlane Lake Mining Limited (NEO: MLM) (OTCQB: MLMLF) ("McFarlane" or the "Company"), a Canadian mineral exploration and development company, is pleased to provide a further update on the progress made at the Company's High Lake property in Ontario, near the Ontario-Manitoba Border. McFarlane completed 46 holes totalling just over 10,000 metres and is awaiting assays for a handful of holes.

Drilling in hole MLM-22-45 intersected a broad mineralized zone of 9.20 g/t gold over 26.4 metres from 292.1 to 318.5 as measured in drill core length from surface, including 15.43 g/t gold over 4.6 metres. The elevation of the broader intersection was -285.3m below surface.

"The Purdex Zone continues to deliver world-class gold intersections both near surface and at depth. Our High Lake property hasn't seen this intensity of drilling in its history but has proved if you are willing to do the work, the gold mineralization is there to be found," said Mark Trevisiol, CEO of McFarlane Lake Mining.

The mineralized zone in hole MLM-25-45 was comprised of altered mafic volcanics and quartz-feldspar porphyry intruded by numerous quartz-tourmaline veins. The zone occurs at the contact between the metasediments and mafic metavolcanics.

"Follow-up drilling in drill hole MLHL-22-45, above previously reported drill hole MLHL-22-06 (24.96 gpt Au over 14.9m), has confirmed the widening and high-grade nature of the Purdex Zone in this area," said Bob Kusins, Vice President of Geology at McFarlane. "We look forward to continuing exploration on our prospective target areas and developing a compliant resource on the Purdex Zone."

The Company released previous drill results showing attractive gold mineralization at High Lake on December 12, 2022, January 9, 2023, January 25, 2023, February 7, 2023, and February 28, 2023.

The mineralized zone and our current drill results to date with multiple high-grade intersections are shown in figures 1 and 2 below.

"As we wrap up a successful exploration program in the field, we continue to see high-grade intersections in our assays and are eager to see the results of the final holes to be returned," said Roger Emdin, COO of McFarlane. "We look forward to the work of developing and publishing a technical report that includes a mineral resource for the Purdex Zone on our High Lake property later this year."

Significant intersections are summarized in Table 1. Collar locations and details of the holes with assays received are summarized in Table 2.

Results from the remaining holes of the drill program will be released when they are available.

A technical report prepared in accordance with National Instrument 43-101 ("NI 43-101") with respect to the High Lake and West Hawk Lake properties is available under the Company's profile on SEDAR at www.sedar.com and on the Company's website at https://mcfarlanelakemining.com.

QA/QC Control Procedures

McFarlane Lake has implemented a Quality Assurance/ Quality Control (QA/QC) program consistent with industry best practices. The drill core is being logged and sampled at a nearby facility with sawn half-core samples, including QA/QC samples, being sent to an accredited lab (Actlabs) in Thunder Bay, Ontario, for processing. The remaining half core has been retained in a locked facility for future examination. Certified reference material (CRM) standards and blanks are inserted every 10 samples into the sample stream. Gold was analyzed by 30-gram fire assay with AA-finish. Samples above 5 grams per tonne gold were re-assayed for gold with a gravimetric finish, while those above 10 grams per tonne were re-assayed utilizing the pulp metallic method.
