ATAC Resources Ltd. Announces Letter of Intent with Hecla Mining Company

VANCOUVER, Feb. 21, 2023 - ATAC Resources Ltd. ("ATAC") (TSXV: ATC) (OTCQB: ATADF) is pleased to announce that it has signed a non-binding Letter of Intent (the "LOI") with Hecla Mining Company ("Hecla") (NYSE:HL) respecting a proposed transaction pursuant to which Hecla will acquire all of the issued and outstanding shares of ATAC for C$0.14 per ATAC share, payable in shares of Hecla common stock (the "Proposed Transaction"). ATAC shareholders will also receive shares in a new exploration company ("Spinco") which will hold all of ATAC's rights and interests with respect to the Idaho Creek, Catch, Rosy and PIL projects (the "Spinco Assets") as well as ATAC's cash balance following completion of the Proposed Transaction.

Pursuant to the LOI, Hecla intends to make a C$2.0 million strategic investment (the "Strategic Investment") into Spinco in which Hecla will acquire (i) a right of first refusal ("ROFR") to acquire any or all of the Spinco Assets, and (ii) a number of units of Spinco (the "Spinco Units") such that it will own 19.9% of Spinco's issued and outstanding common shares following completion of the Strategic Investment. Each Spinco Unit will contain one common share of Spinco (a "Spinco Share") and one warrant (a "Spinco Warrant"). Each Spinco Warrant will entitle Hecla to purchase one additional Spinco Share for a period of five years at the same price as a Spinco Unit.

The Proposed Transaction represents consideration to ATAC shareholders of C$31 million in Hecla shares and a value of approximately C$8 million in Spinco shares based on Hecla's C$2 million placement¹. ATAC's Board and Management are of the opinion that the Proposed Transaction is in ATAC's best interests. The Hecla shares contemplated to be received provide ATAC shareholders with a premium of 66% based on ATAC's 20-day volume-weighted average price of C$0.0845 as of February 17, 2023, or a 109% premium when including the value of Spinco.

"We believe the Potential Transaction will provide significant value to ATAC shareholders. Hecla is an ideal acquirer for the Rackla Gold Property, given its adjacent Keno Hill mining project and demonstrated commitment to the Yukon and its communities. As an established and successful multi-asset producer, Hecla has the resources, strengths and experience to meaningfully advance the known targets at Rackla and Connaught," stated ATAC president and CEO, Graham Downs. "The spin-out of a new copper-focused exploration company provides additional value to shareholders. With the foundation of our existing copper assets, Spinco will be well positioned to aggressively explore for copper - a key critical metal - throughout BC and Yukon. We look forward to working with the Hecla team to negotiate a binding agreement for the Proposed Transaction, and in partnership subsequently advance the new Spinco."

The LOI is effective from February 17^th, 2023, until the earlier of (i) the execution of a definitive and binding agreement in connection with the Proposed Transaction (the "Definitive Agreement"), and (ii) March 15^th, 2023. The LOI includes customary provisions, including an exclusivity period for its duration. The final structure of the Proposed Transaction will be governed by the terms of the Definitive Agreement. The LOI does not create a binding agreement with Hecla for the Proposed Transaction, and there is no assurance that ATAC and Hecla will reach agreement on the terms of the Definitive Agreement as set out in the LOI or at all. In addition to the parties entering into the Definitive Agreement, completion of the Proposed Transaction is subject to, among other conditions, satisfactory completion of due diligence, voting support of key shareholders, shareholder approval, and TSX Venture Exchange approval.

Agentis Capital Mining Partners is acting as financial advisor to ATAC with regard to the Proposed Transaction. Stikeman Elliott LLP is acting as legal counsel to ATAC.
