Toronto, Ontario--(Newsfile Corp. - May 3, 2023) - Palladium One Mining Inc. (TSXV: PDM) (FSE: 7N11) (OTCQB: NKORF) ("Palladium One" or "PDM") and MetalCorp Limited (TSXV: MTC) ("MetalCorp" or "MTC") are pleased to announce the successful completion of their previously-announced statutory plan of arrangement under the provisions of the Business Corporations Act (Ontario) (the "Arrangement"). Pursuant to the Arrangement, among other things, Palladium One acquired all of the issued and outstanding shares of MetalCorp. The Arrangement became effective at 12:01 a.m. (Toronto time) on May 2, 2023 (the "Effective Time"), resulting in MetalCorp becoming a wholly-owned subsidiary of Palladium One.

Under the terms of the Arrangement, each former MetalCorp shareholder ("MTC Shareholders") is entitled to receive, in exchange for each common share in the capital of MetalCorp (a "MTC Share") held, 0.30 of a common share in the capital of Palladium One (each whole share, a "PDM Share") (the "Exchange Ratio"). Further, under the Arrangement, all options to acquire MTC Shares outstanding immediately prior to the Effective Time are exchanged for stock options to purchase PDM Shares at the Exchange Ratio.

"The deemed value of the MetalCorp acquisition is approximately $3.3 million paid in shares, and for that Palladium One assumes approximately $1.8 million of cash and for the remainder of the purchase price being approximately $1.5 million obtains optionality on both precious metal and critical mineral projects in Ontario, Canada. Importantly, Palladium One assumes a significant pool of assessment credits and therefore has no spending obligations for many years to come," commented Derrick Weyrauch, President and Chief Executive Officer of PDM.

In order to receive the PDM Shares in exchange for their MTC Shares, registered MTC Shareholders are reminded that they must complete, sign and return the letter of transmittal to Computershare Investor Services Inc., in its capacity as depositary under the Arrangement, together with their certificate(s) or DRS statement(s) representing their MTC Shares, in accordance with the tender procedures described in MTC's management information circular dated March 22, 2023 (the "Circular") which is available on SEDAR () under MTC's issuer profile. Any MTC Shares held in the CDS system were automatically deposited under the Arrangement and the beneficial shareholders thereof will receive the PDM Shares at the Exchange Ratio in respect of such MTC Shares.
