Corporate Update – High Lake Drilling Program Shows World-Class Gold Intersections - Geophysical Survey Outlines Extension of Anomaly Next to Existing Gold Intercepts
From Mark Trevisiol, President, CEO and Chair of the Board
When we founded McFarlane Lake Mining, our High Lake property was identified as our most promising exploration target. Historical gold intercepts at surface (9.84 g/t gold over 10 metres) and within 100 metres of surface (11.66 g/t gold over 7.01 metres) had given us good reason to believe so. This coupled with our review of the geology where historically, similar types of Archean gold systems have been known to have continuity of gold mineralization along strike and depth, with some deposits extending thousands of meters at depth and hundreds of meters on surface. Our recent drilling results (highlighted below) have proved up our strategy in a way that exceeded our expectations.
We commenced a 10,000-metre drilling program (the “Drill Program”) at High Lake in early November of last year. Since then, we completed 46 holes totalling 10,438 metres of diamond drilling and intersected some world-class gold intersections, three of which made the top weekly intercepts list on the “Junior Mining Hub” (an organization which lists current worldwide gold exploration results, Figure 1) We were further encouraged by the discovery of a high-grade gold pod within 20 to 30 metres of surface (see figure 2) opening the potential for a sizable bulk sample using low-cost open pit mining methods. Further, our geophysical survey identified a high chargeability anomaly over our existing gold mineralization (see Figure 1A and Figure 5). This anomaly continues east in unexplored ground for 300 metres opening up the potential for more gold discoveries.
We were also attracted to High Lake as it is well-located near the city of Kenora, Ontario and close to power lines, major highways and a skilled labour force to aid future mine development.
- MLHL-22-06 intersected 24.96 grams per tonne of gold over 14.9 metres, from 325.56 to 340.46 metres from surface and was Junior Mining Hub’s top 5 weekly intercepts for week of January 9, 2023
- MLHL-22-17 intersected 148.37 g/t gold over 1.3 metres from 113.20 to 114.50 metres from surface and was Junior Mining Hub’s top 3 weekly intercept for the week of February 10, 2023.
- MLHL-22-45 intersected 9.20 g/t gold over 26.4 metres from 292.1 to 318.5 metres from surface and was Junior Mining Hub’s top 7 weekly intercept for the week of March 3, 2023.
- MLHL-22-40 intersected 6.14 g/t gold over 24.55 metres from 14.61 to 41.80 metres from surface.
- MLHL-22-12 intersected 13.52 g/t gold over 6.5 metres from 229.00 to 235.5 metres from surface.
- MLHL-22-28 intersected 9.82 g/t gold over 9.75 metres from 25.25 to 35.00 metres from surface.
- Holes MLHL-22-45, with MLHL-22-40 and MLHL-22-28 (shown above), has defined a near-surface gold mineralized pod, which has the potential for near-term bulk sample of ore

Our focus for the Drill Program was the Purdex Zone, which had attractive historical resources but had not been tested below 100 metres. This Drill Program has identified several high-grade mineralized trends that extend well below 300 metres (see Figure 3) with some exceptional intercepts (see Table 1) and confirms our outlook that the geology supports a continuance of gold mineralization. This, coupled with our geophysical survey, which further supports the extension of elevated chargeability levels east of our existing drilling (Figure 1A and Figure 5) is a strong indicator that more gold mineralization lies along strike of our existing discoveries.

Geophysical Induced Polarization (“IP”) Survey
A program of IP surveying covering 18.7 line kilometres was completed during January and early February 2023. Surveying was completed on two grids, the eastern grid covering the Purdex zone and a western grid covering the P, R, W and Porphyry zones. Five priority targets, Purdex East, Conglomerate, A-D Extension, Porphyry and Gap, were defined from the survey data as shown in Figure 4.
Figure 4 – IP Chargeability Plan
Purdex East is the continuation of the chargeability anomaly that occurs over the Purdex zone where existing gold mineralization has been identified, this is our highest priority for continued exploration. The zone displays increasing chargeability as it approaches a potential fold nose area which may bode well for additional gold mineralization. To the west along strike, the Purdex zone transgresses into conglomerate units with elevated chargeability, possibly providing a favourable host to gold mineralization. It is very rare that conglomerates carry chargeability. This shows potential for gold mineralization. Details of these two targets are shown in Figure 5.
Figure 5 – IP Chargeability Plan – Purdex Area
Two gold targets are defined on the western grid with favourable chargeability anomalies associated with extensions to known gold mineralization at the A-D Extension and the Gap, as shown in Figure 4. The A-D extension represents the eastward extension of four known gold zones onto McFarlane Lake ground. A potential fold nose, as defined by the IP, may provide a favourable site for gold mineralization. The Gap area is situated between two historical zones, the W and P zones. A chargeability trend between the two zones has not previously been drilled.
The Porphyry target covers historical trenches on surface in the High Lake Porphyry, which have returned copper values of 0.95% and up to 1 g/t of gold over 22.9m (see ODM Report 41, Davies 1965). This large chargeability target remains largely untested with significant potential.
With the successful conclusion of this Drill Program, we will be developing and publishing an NI 43-101 technical report that includes a mineral resource for the Purdex Zone on our High Lake property later this year.
Based on available funding, we are aiming to begin another 10,000-metre drilling program at the High Lake property as the results from the Drill Program indicate gold mineralization is open to the east of the Purdex Zone. Early geophysics data also show anomalies to the east of the Purdex Zone where no drilling has been done and are similar to where the Drill Program intersected high-grade gold mineralization. We also will be investigating the near surface mineralized pod and potential options around its extraction.
Besides High Lake, we are also looking to further explore our West Hawk Lake property later this year. We completed a drill campaign at the property last year and announced results that supported historical reports of gold mineralization.
These are exciting times for the company as we successfully execute our overall strategy. With our high-quality property portfolio that has significant potential to define economic resources, and nearby infrastructure that provides the necessary support for exploration and any potential mine development, as well as our seasoned team with decades of experience in exploration, resource development, mining and processing development, we are well-positioned to provide value for our shareholders.

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.
The technical contents of this news release have been reviewed and approved by Robert Kusins, Vice President of Geology of McFarlane. Mr. Kusins is a qualified person, as defined by NI43-101. However, Mr. Kusins is not independent of the Company by virtue of his position.
