Silver Storm Mining Ltd. ("Silver Storm" or the "Company") (TSX.V: SVRS | FSE: SVR), is pleased to announce that as a result of strong investor demand, the Company and Red Cloud Securities Inc., as lead agent and bookrunner and Ventum Financial Corp., as co-agent (collectively, the "Agents"), have agreed to an additional increase in the size of the previously announced best-efforts private placement (the "Marketed Offering") from gross proceeds of up to C$8,008,000 to gross proceeds of up to C$10,010,000. The upsized Marketed Offering is comprised of the sale of up to 77,000,000 units of the Company (each, a "Unit") at a price of $0.13 per Unit (the "Offering Price").

Mr. Eric Sprott, through 2176423 Ontario Ltd. and current significant shareholder of the Company, has indicated his intention to participate in the Offering

Each Unit will consist of one common share of the Company (each, a "Unit Share") and one common share purchase warrant (each a "Warrant"). Each Warrant shall entitle the holder to purchase one common share (each, a "Warrant Share") at a price of C$0.20 at any time on or before that date which is thirty-six (36) months after the Closing Date (as hereinafter defined).

The Company has granted to the Agents an option, exercisable in full or in part, up to 48 hours prior to the Closing Date, to sell up to an additional 15,400,000 Units at the Offering Price to raise up to an additional C$2,002,000 in gross proceeds (the "Agent's Option", and together with the Marketed Offering, the "Offering").

The Company intends to use the net proceeds from the Offering to commence rehabilitation work of the La Parrilla processing facility, order long lead items required to restart La Parrilla, fund ongoing operations for the next twelve months, and for general corporate and working capital purposes, all as further detailed in the Offering Document.

Subject to compliance with applicable regulatory requirements and in accordance with Part 5A of National Instrument 45-106 - Prospectus Exemptions and in reliance on the Coordinated Blanker Order 45-935 - Exemptions From Certain Conditions of the Listed Issuer Financing Exemption (the "Listed Issuer Financing Exemption"), the Units will be offered for sale to purchasers resident in the provinces of Alberta, British Columbia, Manitoba, Ontario and Saskatchewan. The Unit Shares and Warrant Shares underlying the Units are expected to be immediately freely tradeable under applicable Canadian securities legislation if sold to purchasers' resident in Canada. The Units sold under the Offering may also be issued to purchasers outside of Canada, including to purchaser's resident in the United States and in certain offshore foreign jurisdictions, pursuant to applicable regulatory requirements and in accordance with OSC Rule 72-503 - Distributions Outside Canada ("OSC Rule 72-503"). The Units sold to purchasers in the United States will be made on a private placement basis pursuant to one or more exemptions from registration requirements of the United States Securities Act of 1933, as amended (the "U.S. Securities Act").

Prospective investors in the Offering should read the Amended and Restated Offering Document before making an investment decision.

Eric Sprott through 2176423 Ontario Ltd., a corporation which is beneficially owned by him and which holds greater than 10% of the Company's common shares , has committed to subscribe for 7,700,000 Units in the Offering for an aggregate purchase price of $1,001,000 (the "Insider Participation"). The Insider Participation will be considered a "related party transaction" within the meaning of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company expects to rely on exemptions from the formal valuation and minority shareholder approval requirements provided under MI 61-101 pursuant to section 5.5(a) and section 5.7(1)(a) of MI 61-101, on the basis that the Insider Participation does not exceed 25% of the fair market value of the Company's market capitalization. The Company did not file a material change report in respect of the Insider Participation at least 21 days before expected closing date of the Offering as the Insider Participation was not confirmed prior to the foregoing period.

The Offering is scheduled to close on or about June 5, 2025 (the "Closing Date"), or such other date as the Company and the Agents may agree. Completion of the Offering is subject to certain conditions including but not limited to the receipt of all necessary approvals, including the approval of the TSX Venture Exchange (the "TSXV").

The Agents shall receive a cash commission equal to 6.0% of the gross proceeds of the Offering and broker warrants (each, a "Broker Warrant") equal to 6.0% of the number of Units sold pursuant to the Offering, other than from proceeds received from sales to certain President's List purchasers identified by the Company, for which a 2.0% cash commission and 2.0% Broker Warrants will be payable. Each Broker Warrant is exercisable into one common share of the Company at the Offering Price for a period of thirty-six (36) months following the completion of the Offering.

The securities have not been and will not be registered under the U.S. Securities Act, as amended or any state securities laws and may not be offered or sold within the United States or to U.S. Persons unless registered under the U.S. Securities Act and applicable state securities laws or an exemption from such registration is available.

Cautionary Note Regarding Forward Looking Statements:

Certain statements in this news release are forward-looking and involve a number of risks and uncertainties. Such forward-looking statements are within the meaning of the phrase 'forward-looking information' in the Canadian Securities Administrators' National Instrument 51-102 - Continuous Disclosure Obligations. Forward-looking statements are not comprised of historical facts. Forward-looking statements include estimates and statements that describe the Company's future plans, objectives or goals, including words to the effect that the Company or management expects a stated condition or result to occur. Forward-looking statements may be identified by such terms as "believes", "anticipates", "expects", "estimates", "may", "could", "would", "will", or "plan". Since forward-looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent risks and uncertainties. Although these statements are based on information currently available to the Company, the Company provides no assurance that actual results will meet management's expectations. Risks, uncertainties and other factors involved with forward-looking information could cause actual events, results, performance, prospects and opportunities to differ materially from those expressed or implied by such forward-looking information. Forward-looking information in this news release includes, but is not limited to, the Company completing the Offering as planned and on the terms presented, the intended use of proceeds of the Offering, the closing conditions of the Offering, TSXV approval of the Offering, the anticipated closing date of the Offering, statements with respect to the Insider Participation, including the terms and quantum thereof, the Company's plans and expectations for La Parrilla, and the ability to eventually place the La Parrilla Complex back into production.

In making the forward-looking statements included in this news release, the Company have applied several material assumptions, including that the Offering will close on the anticipated terms or at all or may not close on the terms and conditions currently anticipated by the Company; that the Units will have the anticipated terms; that the Company will use the net proceeds of the Offering as anticipated; that the Company will receive all necessary approvals in respect of the Offering; that the Insider Participation will be completed on the contemplated terms; the Company´s financial condition and development plans do not change because of unforeseen events, and management's ability to execute its business strategy and no unexpected or adverse regulatory changes with respect to La Parrilla, the decision to potentially place La Parrilla into production, other production related decisions or to otherwise carry out mining and processing operations, being largely based on internal non-public Company data and reports from previous operations and not based on NI 43-101 compliant reserve estimates, preliminary economic assessments, pre-feasibility or feasibility studies, resulting in higher risks than would be the case if a feasibility study were completed and relied upon to make a production decision. Forward-looking statements and information are subject to various known and unknown risks and uncertainties, many of which are beyond the ability of the Company to control or predict, that may cause the Company's actual results, performance or achievements to be materially different from those expressed or implied thereby, and are developed based on assumptions about such risks, uncertainties and other factors set out herein.
