CEO.CA Chairman's Briefing

Toronto, Ontario--(Newsfile Corp. - April 21, 2022) - McFarlane Lake Mining Limited (NEO: MLM) ("McFarlane" or the "Company"), a Canadian mineral exploration and development company, is pleased to provide an update of the progress made at the Company's West Hawk Lake property in Manitoba, near the Ontario-Manitoba Border. A technical report (the "Technical Report") prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") with respect to the West Hawk Lake and High 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/.

The first two drill holes of McFarlane's 3,000m drill program conducted this year have successfully intersected the historic Waverly Raise Zone and expanded the zone laterally with intersections in both MLWH-22-01 and MLWH-22-02.

2022 Drilling Highlights of Waverly Raise Zone include:

• MLWH-22-01 intersected two zones, 22.17g/t gold over 1.27m including 49.4g/t gold over 0.55m, and 9.85g/t gold over 1.62m.

• MLWH-22-02 intersected a single zone of 9.88g/t over 1.0m.

Past Drilling (2012) Highlights in Waverly Raise Zone include:

• CSM WH-12-05 intersected 24.68 g/t over 2.6 m.

• CSM WH-12-07 intersected 19.55 g/t over 1.3 m.

The intersections have expanded upon the previous drilling program conducted by Canadian Star Minerals Ltd. ("CSM") in 2012 at the Waverly Raise Zone, outlined in the Technical Report. The drill program has expanded the Waverly Raise Zone for a total length of 150m with the Waverly Raise Zone remaining open to depth and discovery of additional shoots along the established structural corridor and IP geophysics trend (Figure 1).

Drilling Program at West Hawk Lake

McFarlane initiated a 3,000m drill program in January 2022 to confirm past reported gold mineralization and to follow up on geophysical targets. Assay results from the first six holes have been received from the fifteen-hole program (which includes one abandoned hole). The drill program has confirmed prospective trends established by previous drilling and the recently completed IP survey, which outlined a number of favourable trends and anomalies (please refer to McFarlane's news release dated March 21, 2022).

Drilling has intersected zones of sheared and altered quartz monzonite with local sections of quartz veining mineralized with fine pyrite, arsenopyrite and locally minor chalcopyrite and sphalerite. Gold mineralization often occurs within these more mineralized intervals. Thin mafic dikes frequently intrude these sheared sections and the dikes are subsequently sheared, altered and mineralized.

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

Table 1: Significant Intersections.

Because insufficient drilling has been conducted to determine true width, the results are reported as core length.

Table 2: Collar Location Details (NAD83 Zone 15).

Results from the remaining nine holes of the drill program have been submitted to the lab and will be reported upon completion.

QA/QC Control Procedures

McFarlane 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 for processing. The remaining half core has been retained in a locked facility for future examination. Certified reference material 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 were re-assayed for gold with a gravimetric finish, while those above 10 grams per tonne were re-assayed utilizing the pulp metallic method.
