ATEX Resources Inc. (TSX-V: ATX) (OTCQB: ATXRF) is pleased to announce the closing of its previously announced and now upsized bought deal financing of 42,262,500 units of the Company at a price per Unit of C$2.60 for aggregate gross proceeds to the Company of approximately C$110 million, including the full exercise of the Underwriters’ option.

Each Unit is comprised of one common share and one warrant which entitles the holder thereof to acquire one common share at a price of C$4.00 per share on or prior to November 6, 2029, subject to acceleration as further set out in the warrant indenture governing the warrants, a copy of which is being filed under the Company’s profile on SEDAR+.

ATEX intends to use the net proceeds from the Offering for exploration and development of the Valeriano Project and for general working capital purposes.

BMO Capital Markets, as the sole bookrunner and co-lead underwriter, and Desjardins Capital Markets as co-lead underwriter on behalf of a syndicate of underwriters that included Stifel Nicolaus Canada Inc., Ventum Financial Corp., Cormark Securities Inc., Paradigm Capital Inc. and TD Securities Inc. acted as underwriters of the Offering. In connection with the Offering, the Underwriters received a cash fee of C$3,844,425, representing 5.00% of the gross proceeds from the Offering, subject to a reduced fee of 2.00% in respect of certain purchasers identified on a president’s list agreed to between the Company and the Underwriters.

The Offering remains subject to the final acceptance of the TSX Venture Exchange. The securities issued under the Offering are subject to a hold period of four months and one day from the date hereof.

Certain insiders of ATEX subscribed for a total of 9,500,000 Units. Each subscription by an Insider is considered a “related party transaction” of ATEX for purposes of Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions and Policy 5.9 – Protection of Minority Security Holders in Special Transactions of the TSX Venture Exchange. The Company is exempt from the requirements to obtain a formal valuation or minority shareholder approval in connection with the subscriptions by such Insiders in reliance on Sections 5.5(a) and 5.7(1)(a) of MI 61-101 as neither the fair market value of any securities issued to, nor the consideration paid by, the Insiders exceeded 25% of the Company’s market capitalization. The Company did not file a material change report 21 days prior to closing of the Offering, as the Insiders’ participation had not been confirmed at that time and the Company wished to close the transaction as soon as practicable for sound business reasons.
