The Company is also pleased to provide an update on its proposed acquisition (the "Transaction") of all of the issued and outstanding shares of Aurea Mining Inc. ("Aurea Mining"), a wholly owned subsidiary of Argonaut Gold Inc. ("Argonaut"), which through Aurea Mining's wholly owned subsidiary Minera Aurea S.A. de C.V. ("Minera Aurea"), holds a 100% indirect interest in and to the Ana Paula Gold project (the "Ana Paula Gold Project"), as well as its option agreement (the "Option Agreement") with Argonaut and its wholly owned subsidiary, Compañía Minera Pitalla S.A. de CV, pursuant to which the Company has been granted an option (the "Option") to acquire a 100% interest in the San Antonio Gold project (the "San Antonio Gold Project").

Private Placement Details

Each Unit consists of one common share (each, a "Share") in the capital of the Company and one-half of one non-transferable Share purchase warrant (each whole warrant, a "Warrant"). Each Warrant shall entitles the holder thereof to purchase one additional Share (each, a "Warrant Share") at an exercise price of C$0.30 per Warrant Share for a period of thirty-six (36) months following the date of issuance (the "Date of Issue").

Aggregate finder's fees of $554,700 in cash were paid and 2,521,461 non-transferable broker warrants (each, a "Broker Warrant") were issued to three qualified finders. Each Broker Warrant is exercisable into one Share (each a "Broker Warrant Share") at an exercise price of $0.30 per Common for a period of thirty-six (36) months following the Date of Issue.

The proceeds from the Offering are anticipated to be used for the purchase and subsequent exploration advancement of the Ana Paula Gold Project as well as for general working capital purposes. All securities issued in connection with the Offering are subject to a four month and one-day restricted resale period.

Each of Charles Funk (Chief Executive Officer), Sam Anderson (VP Exploration) and Mahesh Liyanage (Chief Financial Officer) (collectively, the "Insiders"), participated in the Offering. Accordingly, each of their respective subscriptions constituted a "related party transaction" within the meaning of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The issuance of the Units to the Insiders, however, was exempt from the valuation requirements of MI 61-101 by the virtue of the exemption contained in section 5.5(b) as the Shares are not listed on a specified market and from the minority shareholder approval requirements of MI 61-101 by virtue of the exemption contained in Section 5.7(1)(a) as the value of the Units issued under the Offering did not exceed 25% of the Company's market capitalization.

None of the securities issued in the Offering will be registered under the United States Securities Act of 1933, as amended (the "1933 Act"), and none of them may be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the 1933 Act. This news release shall not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of the securities in any state where such offer, solicitation, or sale would be unlawful.

Transaction Update

By way of update, the Company and Argonaut Gold Inc. ("Argonaut") continue to work towards the closing of the Transaction and have met several of the conditions for the closing of the Transaction (the "Closing"). Accordingly, Heliostar received conditional approval from the TSX Venture Exchange ("TSXV") for the Transaction on March 9, 2023. The Closing remains subject to, among other things, the final approval of the TSXV, as the Transaction constitutes a Fundamental Acquisition as defined in TSXV Policy 5.3 - Acquisitions and Dispositions of Non-Cash Assets. Further to Heliostar's December 5, 2022, January 17, 2023 and March 3, 2023 news releases, the Company has yet to receive conditional approval from the TSXV for the grant of the Option under the terms of the Option Agreement. The Company continues to work towards obtaining receipt of conditional approval from the TSXV for the Option, following which it may, pursuant to the terms of the Option Agreement, earn a 100% interest in and to the San Antonio Gold Project located in Baja California Sur State, Mexico.
