BLUE THUNDER ANNOUNCES IMPORTANT TECHNICAL COLLABORATION PLUS INVESTMENT BY IAMGOLD

Blue Thunder Mining Inc. has renewed its focus on gold exploration in Quebec with the technical and financial support of Iamgold Corp.

Dorian L. (Dusty) Nicol, CEO of Blue Thunder, stated, "This important technical collaboration and investment by IAMGOLD is a major milestone for Blue Thunder. We look forward to working with the IAMGOLD team to advance our Muus project in Chibougamau, Quebec, as well as other projects in Quebec that may be acquired in the future. The Muus Gold Project is adjacent to, and on trend with, IAMGOLD's 5-million-ounce Nelligan Gold project and IAMGOLD's in depth knowledge of the district will be invaluable in advancing our exploration efforts. As part of our renewed focus on Quebec exploration and development, we will be re-domiciling the company in Quebec."

Advisory Committee

An advisory technical committee (the "Technical Committee") will be formed consisting of two nominees of Blue Thunder and two nominees of IAMGOLD. The mandate of the Technical Committee will be to facilitate the exchange of technical information and ideas to assist Blue Thunder in planning the further exploration of the Muus Project and potentially other Quebec projects it may acquire in the future. The Company looks forward to receiving the benefit of IAMGOLD's extensive knowledge of Quebec geology and mineral deposits through its participation in this advisory Technical Committee.

Strategic Investment by IAMGOLD

Blue Thunder is announcing a non-brokered private placement of common shares for gross proceeds of up to $1,000,000 (the "Private Placement"). The Private Placement consists of a minimum of $750,000 hard dollars and an up to $250,000 flow-through component. IAMGOLD will become a strategic shareholder of Blue Thunder by investing $500,000 in the hard dollar component of the Private Placement, acquiring approximately 14% of the Company's shares on closing of the Private Placement.

Muus Project

The Muus Project comprises mineral claims totaling about 25,250 hectares of ground in the eastern part of the Archean Abitibi Greenstone Belt, located approximatively 60 kilometers southwest of the Chibougamau mining camp, which historically has produced three billion pounds of copper and four million ounces of gold. The Muus Project is underlain by several key regional geologic structures, including the Guercheville Deformation Zone and the Fancamp Deformation Zone. These structures are associated with many of the known gold deposits and occurrences in the district, including IAMGOLD's Nelligan deposit (5 million ounces Au) and its Monster Lake deposit (about 430,000 ounces Au grading over 12 g/t Au), which occur on neighbouring properties and on-strike with Muus.

Historical exploration in the district primarily targeted structurally controlled Archean lode gold and copper systems as well as volcanic hosted massive sulfide ("VMS") mineralization. The discovery of the Nelligan gold deposit highlights the potential for large, bulk tonnage, sediment-hosted gold deposits, as the host rocks and controlling structures at Nelligan extend onto Muus. The Muus Project hosts numerous underexplored mineralized occurrences. Work to date has comprised prospecting, trenching, ground geophysics, and limited diamond drilling, which has identified numerous targets which merit further detailed exploration. Field work completed during 2022 established that the northern portion of the Muus Project is prospective for copper-gold volcanogenic massive sulphide mineralization.

Private Placement

The hard dollar component of the Private Placement involves the sale of at least 10,714,285 common shares (each a "HD Share") at a price of $0.07 per HD Share ("HD Issue Price") for gross proceeds of a minimum of $750,000. The flow-through component of the Private Placement involves the sale of up to 3,333,333 flow-through shares (each a "FT Share") at a price of $0.075 per FT Share for aggregate proceeds of up to $250,000. The proceeds from the flow-through offering will be used to fund exploration programs on one or more of the Company's exploration properties located in Quebec that will qualify as "Canadian Exploration Expenses" and once renounced, "flow-through mining expenditures", as those terms are defined in the Income Tax Act (Canada). The proceeds of the hard dollar component of the Private Placement will be used for further exploration of the Company's Muus Gold Project and for general corporate purposes.

IAMGOLD will be investing $500,000 in the hard dollar component of the Private Placement and will hold approximately 14% of the issued and outstanding common shares of Blue Thunder upon closing of the Private Placement. IAMGOLD will enter into an investor rights agreement with the Company concurrently with the closing of the Private Placement which will entitle IAMGOLD to nominate one director to the Company's board of directors and to participate in future financings as long as IAMGOLD continues to hold at least 10% of the Company's shares. IAMGOLD has agreed not to sell any of the HD Shares it purchases in the Private Placement for a period of 12 months from closing.

Chad Williams, Chairman of Blue Thunder, is subscribing for 1,628,571 HD Shares and 1,146,666 FT Shares for total gross proceeds to the Company of $200,000 and will hold approximately 21% of the issued and outstanding common shares of Blue Thunder upon closing of the Private Placement. Insiders' participation in the Private Placement constitutes a "related party transaction" pursuant to Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company is relying on the exemption from minority shareholder approval and formal valuation requirements of MI 61-101, as the fair market value of the insiders' participation in the Private Placement does not exceed 25% of the market capitalization of the Company.

The closing dates for the Private Placement are expected to occur on or before November 17, 2023, for the HD shares and December 1, 2023, for the FT shares (the "Closing Dates") and is subject to the completion of formal documentation and receipt of the approval of the TSX Venture Exchange. Other than the common shares sold to IAMGOLD, which are subject to a 12 month hold period, the HD shares and FT shares sold in the Private Placement will be subject to a four month hold period from the date of closing of the Private Placement under applicable Canadian securities laws. Finder's fees may be payable in connection with the Private Placement.

Critical Metals Update

The Company previously announced that it was focusing its attention on critical minerals opportunities and announced that it had entered into an agreement to acquire certain critical metals properties in the Yukon ("Yukon Transaction") (see news releases of July 11 and August 1, 2023) and announced that it had acquired rights in respect of a lithium property in Nevada (see news release of July 20, 2023). The Company subsequently determined that it is in the Company's best interests not to pursue critical minerals opportunities, but to refocus its efforts on advancing the Muus Gold-Copper Project and potentially other properties in Quebec. The Yukon Transaction has been terminated by mutual consent of the parties. The Company is considering how the Nevada lithium project may fit with the Company's ongoing strategy and may evaluate the potential for selling it. The Nevada lithium project is not material to the Company.This news release does not constitute an offer to sell, or a solicitation of an offer to buy, any of the securities in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act") 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.

The Muus Gold project covers approximately 23,500 hectares of prospective ground in the eastern part of the Abitibi Greenstone Belt. The Muus Project is prospective for gold mineralization, as it is on strike from Iamgold's 5-million-ounce Nelligan gold project. Field work completed during 2022 established that the northern portion of the Muus Project is prospective for copper-gold volcanogenic massive sulphide mineralization.
