As consideration for the acquisition, First Mining issued to Chalice 32,260,836 common shares (the 'Consideration Shares'), representing approximately 8.1% of the issued and outstanding shares of First Mining as of today's date.

First Mining has retained the right to repurchase 0.5% of the NSR royalty for CDN$1,000,000.

This is our third significant acquisition in north-western Ontario and we believe that the Cameron project complements our growing portfolio of advanced assets with sizeable in-situ gold resources in geopolitically safe regions.
