VANCOUVER, Dec. 21, 2020 - Eclipse Gold Mining Corp. ("Eclipse") (TSXV: EGLD) (OTC: EGLPF) and Northern Vertex Mining Corp. ("Northern Vertex") (TSXV: NEE) (OTC-NASDAQ Intl: NHVCF) are pleased to announce that, further to the companies' press release dated December 7, 2020 and the Eclipse press release dated December 15, 2020, Eclipse has successfully completed the book build for its previously announced private placement of subscription receipts in the amount of C$20 million (the "Offering"). As a result of the strong expressions of interest received, Eclipse has granted an option (the "Agents' Option") to the syndicate of agents led by Stifel GMP and including Canaccord Genuity Corp., Raymond James Ltd., Beacon Securities Limited, and PI Financial Corp (the "Agents"), entitling the Agents to sell, on Eclipse's behalf, up to an additional 8 million subscription receipts at C$0.50 per subscription receipt for additional gross proceeds of up to C$4 million.

Douglas J. Hurst, proposed Chairman of the combined company stated, "The support reflected in this over-subscribed financing validates our vision for the company. For us as shareholders, management, and the Board, this demonstrates alignment with investors on our views regarding the exploration upside offered by Moss and Hercules, and the value of operating cash flow."

Kenneth Berry, President, CEO and Director stated, "With a strengthened balance sheet we look forward to advancing the Moss mine and systematically exploring both the Moss and Hercules properties. The potential of both properties provides a unique opportunity for value generation and growth of the combined company."

The Offering is in connection with the proposed plan of arrangement transaction (the "Transaction") between Northern Vertex and Eclipse that was announced on December 7, 2020.

All other terms of the Offering and the Transaction as set out in the December 7 and December 15, 2020 press releases remain the same. The Offering is currently expected to close on or before January 14, 2021, subject to standard industry conditions, including, but not limited to, receipt of approval by the TSXV, the entering into of an agency agreement between Eclipse and the Agents and the return of properly completed subscription agreements.
