Proposed Acquisition OF Tintic Consolidated Metals

MONTRÉAL - Osisko Development Corp. has entered into definitive agreements with IG Tintic LLC and Ruby Hollow LLC to acquire 100% of Tintic Consolidated Metals LLC. On completion of the Transaction, Osisko Development will acquire 100% ownership of the producing Trixie Mine, as well as mineral claims covering more than 17,000 acres (including over 14,200 acres of which are patented) in Central Utah’s historic Tintic Mining District. Tintic’s recent discovery of an ultra-high grade structure (“T2”) positions Trixie as one of the highest grade gold mines in the world. Ongoing exploration work has demonstrated significant potential for expansion and further discovery both at Trixie and over the broader land package.
