First Majestic Silver Corp. purchased C$2.0 million of the Private Placement. The Company issued a total of 8,750,000 units ("Units") at a price of C$0.80 per Unit for gross proceeds of C$7.0 million. Each Unit consisted of one common share of the Company ("Common Share") and one-half of one common share purchase warrant (each whole warrant, a "Warrant").

Each Finder Warrant entitles the holder to acquire one Common Share at an exercise price of C$1.20 until November 3, 2023.
