MacDonald Mines Exploration Ltd. announced the start of a 1,200 meter drill program along the prospective McLaren Lake Fault Zone ("MLFZ") at the Alwyn Copper-Gold ("Cu-Au") trend ("Alwyn"), as well as the Glade Gold ("Glade") located on MacDonald Mines' 100% owned SPJ Project near Sudbury, Ontario. The Company also reports preliminary mineralogical observations from hole AW-23-106. Mineralogical observations from hole AW- 23-106 support the Alwyn Cu-Au mineralized system's affiliation with metasomatic iron and alkali-calcic ("MIAC") mineral systems capable of forming iron-rich copper-gold mineralization.

Chalcopyrite associated with actinolite (Fe-rich amphibole) and andradite garnet (Fe-rich garnet) is interpreted to represent iron seeping into the system to form iron-silicate alteration associated with chalcopyrite mineralization. This suggests a potential for the gravity anomalies detected in the Alwyn Cu-AU trend to represent areas of stronger Fe alteration and to potentially host zones of iron-rich alteration affiliated with iron oxide-copper-gold (IOCG) mineralization. Drilling of up to 1,000 meters at the Alwyn Cu-Ai trend commenced on June 8th, 2023, aiming to: Expand the footprints laterally and at depth of the vein networks mineralized in copper and gold identified during the 2022 drilling program and indicated by historical drilling (AFRI 41I10NE0158), Test the association between gravity highs and hydrothermal iron enrichments that could be suggestive of the presence of iron-rich copper-gold Mineralization affiliated with iron oxide copper-gold ("IOCG") mineralization in the Alwyn Cu- Au trend.

Drilling integrates new data that supports the extension of copper-gold mineralization outside of the area of the Awlyn Cu-Au trend drilled in 2022 that includes: The results from the 2023 gravity survey and 10 new targets generated by ALS GoldSpot in the Alwyn Cu- au trend, which could expand the size of the Cu-Au mineralized System and confirm the relationship between iron-rich alteration/mineralization and the gravity anomalies and targets identified in collaboration with ALS GoldSpot.
