Mineralization Comments

Dec 05, 2018 (Therese Pettigrew) - The Lacobeer Lake zone is poorly defined owing to thick overburden. Work to date includes five trenches but only one of them intersected mineralization. The zone is inferred to be a maximum of 25 m thick on surface with complicated textural relationships within Marathon Series gabbros. The best grab sample from prospecting contained 2.6 g/t PGM and 0.53% Cu (Assessment file 20000014536).
