Westgold has received total consideration of $54.4M comprising a $25M cash payment (including the $1M deposit already received1 ) and a 19.9% shareholding in Great Boulder valued at $29.4M2 . Westgold will also receive a 1.0% Net Smelter Return (NSR) royalty over all future gold production from Peak Hill. The Transaction aligns with Westgold’s strategy to simplify its portfolio and bring forward value for its shareholders from non-core, non-producing assets. Westgold Managing Director and CEO Wayne Bramwell commented: “The sale of Peak Hill is consistent with Westgold’s strategy to streamline our portfolio and focus on our larger, core operating hubs. The sale to Great Boulder is transformational for them and the upfront cash payment and equity exposure delivers immediate value for Westgold shareholders. Our shareholders also retain exposure to the project’s upside potential through a 1.0% NSR royalty, whilst Great Boulder gains access to a processing solution through Westgold’s Murchison hubs. We look forward to the Great Boulder team rapidly advancing Peak Hill and a longer-term relationship across the broader Murchison region.” Advisers Argonaut acted as financial adviser and Thomsons as legal adviser to Westgold in relation to the Transaction.
