McFarlane Files Technical Report on its High Grade Gold Resource on High Lake Property, Includes Technical Update on West Hawk Lake Property

TORONTO, CANADA, July 5, 2023 – McFarlane Lake Mining Limited (NEO: MLM) (OTCQB: MLMLF) (“McFarlane Lake” or the “Company”), a Canadian gold exploration and development company, is pleased to announce the filing of an independent Technical Report (the “Technical Report”) prepared in accordance with National Instrument 43-101 for the 100% owned High Lake Property west of Kenora, Ontario and the West Hawk Lake property in Manitoba 10 kilometres west of the High Lake property. The Technical Report includes an Initial Mineral Resource Estimate (“MRE”), previously announced (see table 1), of the Purdex Zone on the High Lake Property

The Technical Report titled “Technical Report and Initial Mineral Resource Estimate of The High Lake – West Hawk Lake Gold Project, Kenora Mining Division, Ontario and Falcon Lake Area, Manitoba” was independently prepared by P&E Mining Consultants and is dated June 30, 2023, and supports the disclosure made by the Corporation in its May 24, 2023 press release announcing an Initial Mineral Resource Estimate. There are no differences between the Technical Report and the information disclosed in the May 24, 2023, news release.

The Technical Report can be found under the Corporation’s profile on SEDAR ( and on the Corporation’s website (

The MRE, independently prepared by P&E Mining Consultants Inc., has been classified in accordance with CIM Definition Standards on Mineral Resources and Mineral Reserves (CIM, 2014) and follows the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (CIM, 2019). It is based on our recently completed drilling program and mineralization modelling with an effective date of April 14, 2023.

  1. The mineral resources described above have been prepared in accordance with the CIM Standards (Canadian Institute of Mining, Metallurgy, and Petroleum, 2014) and follow Best Practices outlined by CIM (2019)
  2. Underground Mineral Resources have been reported using a 2.6 g/t lower cut-off based on US$1,800/oz Au, 0.77 US$ FX, 95% process recovery and costs of C$130/t mining, C$40/t processing and $15/t G&A.
  3. The High Lake deposit has been classified as Inferred and Indicated Mineral Resources according to drill spacing and two grade estimation passes. Underground Mineral Resources have been classified manually within a constraining volume to remove isolated areas not satisfying reasonable prospects for eventual economic extraction (“RPEEE”) and have been reported using an approximate 2 m minimum thickness.
  4. There are no known underground workings at the High Lake Deposit
  5. The bulk density of 2.7 t/m3has been applied based on measurements taken on the drill core and assigned in the block model.
  6. The MRE is based on a block models with a block size of 0.5 m x 0.5 m x 0.5 m.
  7. Tonnage has been expressed in the metric system, and gold metal content has been expressed in troy ounces.
  8. The tonnages have been rounded to the nearest 100 tonnes and the metal content has been rounded to the nearest 100 ounces. Gold grades have been reported to two decimal places.

These Mineral Resources are not Mineral Reserves as they have not demonstrated economic viability. The quantity and grade of reported Inferred Mineral Resources in this news release are uncertain in nature and there has been insufficient exploration to define these Mineral Resources as Indicated or Measured; however, it is reasonably expected that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

The mineralized zone on the Purdex Zone extends to surface and there may be an opportunity to mine these Mineral Resources early in a development project through an open pit. P&E has reviewed two potentially feasible pit options and subsets of the Mineral Resource that could be exploited through these options, which are outlined in Table 2 below.
