(TSXV: PPP; OTCQB: PMCOF; Frankfurt: 1ET0) today announced key additions to the Technical and Corporate team. The Company is also providing an update to its upcoming drill program and the proposed transaction (the “Transaction”) with BeMetals Corp.

Highlights

⦁ Prospector has received conditional TSX Venture Exchange approval to sell its non-Yukon assets (See “Assets Portfolio” below) for 29,400,000 Consideration Shares.

⦁ In connection with closing the Transaction, Prospector plans to distribute the Consideration Shares to its shareholders on a pro-rata basis, with a date of record to be announced shortly.

⦁ BeMetals will be renamed Lightning Resource Corp after the transaction is completed. BeMetals has completed a 10:1 consolidation (the “Consolidation”) and is now trading on a post-consolidation basis.

Benefits for Prospector Shareholders

⦁ Transaction will unlock value in projects that have been overshadowed by the flagship ML Project, Yukon.

⦁ Intended share distribution gives Prospector shareholders direct exposure to a new ground floor opportunity led by proven leadership.
