Toronto, Ontario – November 24, 2025 – 1290448 B.C. Ltd. (the “Company”) and Investmin Resources Inc. (“Investmin”) are pleased to announce the closing of Investmin’s previously announced private placement financing of Subscription Receipts (as defined herein) for aggregate gross proceeds of approximately $106,897,000, including the exercise of a portion of the Agents' Option (as defined herein). The Financing (as defined herein) was undertaken in connection with the proposed business combination and reverse take-over transaction involving the Company and Investmin, which was previously announced by the Company on October 22, 2025 (the “Transaction”).

Pursuant to the Financing, Investmin issued 106,897,000 subscription receipts (the “Subscription Receipts”) at a price of CAD$1.00 per Subscription Receipt (the “Issue Price”), of which 106,288,000 Subscription Receipts were issued on a brokered private placement basis (the “Brokered Financing”) and 609,000 Subscription Receipts were issued on a non-brokered private placement basis (the “Concurrent Financing”, and together with the Brokered Financing, the “Financing”). A second closing of the Financing is expected in the future and will be announced by the Company.

 The Brokered Financing was led by SCP Resource Finance LP (“SCP”) and Paradigm Capital Inc. (together with SCP, the “Lead Agents”), on behalf of themselves and a syndicate of agents, including Canaccord Genuity Corp. and Cormark Securities Inc. (collectively with the Lead Agents, the “Agents”). The Agents were granted an option (the “Agents’ Option”), exercisable in whole or in part, at any time up to three business days prior to the latest closing date to arrange for the purchase and sale of up to an additional 15,000,000 Subscription Receipts at the Issue Price for additional gross proceeds of up $15,000,000, of which 6,288,000 has been exercised and 8,712,000 remains exercisable.

The net proceeds of the Financing have been deposited into escrow and are being held in trust pending the satisfaction of certain escrow release conditions in connection with the Transaction (the “Escrow Release Conditions”), and, following the completion of the Transaction, will be used to fund Investmin’s acquisition of a certain group of mining claims situated in Pershing County, Nevada (the “Property”) from Rosebud Exploration LLC (the “Acquisition”), exploration of the Property, as well as for general corporate and working capital purposes. The Property consists of 226 unpatented load mining claims covering approximately 1,809 acres (732 hectares) that are on U.S. Bureau of Land Management (BLM) lands and includes the former Rosebud mine, which produced nearly 400,000 oz gold and 2,300,000 oz silver between 1997 and 2000. Certain members of Investmin management participated in the Financing.

Each Subscription Receipt entitles the holder thereof to receive one common share of Investmin (each, an “Investmin Share”). Each Subscription Receipt will be automatically converted (for no further consideration and with no further action on the part of the holder thereof) upon the satisfaction of certain of the Escrow Release Conditions in connection with the Transaction on or before the escrow release deadline for one Investmin Share immediately before completion of the Transaction. Immediately after the conversion of the Subscription Receipts, each Investmin Share issued pursuant to the conversion of the Subscription Receipts will be automatically exchanged into common shares (the “Resulting Issuer Shares”) of the entity resulting from the Transaction. Prior to completion of the Transaction (the “Closing”), it is a condition to completion of the Transaction that: (i) the common shares of the Company (the “Company Shares”), including any Company Shares issued pursuant to private placement offerings completed by the Company, be adjusted such that the Company's shareholders receive, in aggregate, that number of Resulting Issuer Shares that results in such shareholders holding approximately 1.66 million Resulting Issuer Shares (which represents 10% of the total number of issued and outstanding Company Shares and Investmin Shares immediately before the Closing); and (ii) the shareholders of Investmin (inclusive of purchasers in the Financing) receiving Resulting Issuer Shares on a one-for-one basis in exchange for their Investmin Shares that are issued and outstanding.

In connection with the Financing, Investmin and the Company (as well as certain related entities of such parties) will execute an amalgamation agreement (the “Amalgamation Agreement”), pursuant to which , such parties will consummate a three-cornered amalgamation that will result in the reverse take-over of the Company by the shareholders of Investmin, culminating in the listing of the Resulting Issuer Shares on a Canadian stock exchange and a name change of the Company to “Blossom Gold Inc.”, which will thereafter carry on the business of Investmin.

Subject to the satisfaction or waiver of the conditions precedent set out in the binding letter agreement between Investmin and the Company dated October 21, 2025 and the Amalgamation Agreement, the Transaction is expected to close in January 2026.
