Osisko announces sale of Brucejack offtake to Pretium

Sean Roosen, Chair of the Board and CEO of Osisko stated: “The sale of Osisko’s offtake contract on the Brucejack mine will result in the elimination of a low margin offtake contract and allow better utilization of our working capital. Since acquiring the Orion portfolio in 2017, we now have received approximately US$164.3 million from Pretium, including proceeds from the buyback of the stream and sale of the offtake as well as cash margins to date from the offtake, compared to a book value of approximately US$147.3 million for our investment in Pretium.”

The Sale is expected to close on September 30^th 2019 (the “Closing Date”). Pretium will make a payment of US$31.2 million to OBL on the Closing Date, with the remainder of the Purchase Price to be paid on November 30, 2019. Osisko expects to use the proceeds from the Sale to fund additional investments. As of the date hereof, OBL will no longer receive any deliveries under the Offtake Agreement. Since purchasing the Offtake Agreement in 2017, OBL has realized approximately US$4.5 million in cash margins[1].

Under the Offtake Agreement, Pretium had an option on December 31^st 2019 to repurchase up to 75% of OBL’s share of the Brucejack gold offtake by making a payment of US$13 per ounce of remaining contained gold under the contract.

Osisko’s 2019 guidance included 500 GEOs from the Brucejack offtake for the fourth quarter.
