(TSX-V: KLDC) (OTCQB: KLKLF) is pleased to announce that further to its news releases dated September 17, 2026 and September 22, 2026, it has closed its previously announced upsized brokered private placement, including the exercise in full of the option granted to the Agents (as defined herein) to increase the size of the Offering. The Offering was conducted pursuant to an agency agreement between the Company, Canaccord Genuity Corp. and CFT Financial Corporation, as co-lead agents and co-bookrunners.

Pursuant to the Offering, the Company has issued: (i) an aggregate of 29,457,000 flow-through common shares at a price of $0.40 per FT Share, for gross proceeds of $11,782,800.00; (ii) an aggregate of 5,714,000 special flow-through common shares at a price of $0.483 per Special FT Share, for gross proceeds of $2,759,862.00; and (iii) an aggregate of 16,066,510 common shares at a price of $0.35 per HD Share, for gross proceeds of $5,623,278.50, representing aggregate gross proceeds of $20,165,940.50. Each of the FT Shares and Special FT Shares will qualify as a “flow-through share” for the purposes of the Income Tax Act (Canada).

The Offering included a lead order strategic investment from renowned resource investor, Mr. Eric Sprott. “We are thrilled to welcome Eric’s continued support as a cornerstone investor,” said Stefan Sklepowicz, Chief Executive Officer of the Company. “We view his participation as a strong endorsement of our team and the potential of our Kirkland Lake portfolio, and this Offering positions us well to advance our drill-ready targets.”

Pursuant to the provisions in the Income Tax Act (Canada), the gross proceeds received by the Company from the sale of the FT Shares and the Special FT Shares will be used to incur eligible “Canadian exploration expenses” that qualify as “flow-through mining expenditures” as both terms are defined in the Income Tax Act (Canada) on or before December 31, 2027, and the Company will renounce all the Qualifying Expenditures in favour of the subscribers of the FT Shares and the Special FT Shares with an effective date of no later than December 31, 2026. In the event the Company is unable to renounce Qualifying Expenditures effective on or prior to December 31, 2026 for each FT Share and Special FT Share purchased in an aggregate amount not less than the gross proceeds of the sale of the FT Shares and the Special FT Shares and/or the Qualifying Expenditures are otherwise reduced by the Canada Revenue Agency, the Company will indemnify each subscriber for the additional taxes payable by such subscriber as a result of the Company’s failure to renounce the Qualifying Expenditures or as a result of the reduction as agreed. The net proceeds from the issue and sale of the HD Shares are intended to be used for general corporate purposes.

In consideration for their services rendered in connection with the Offering, the Company paid to the Agents a cash commission and issued to the Agents an aggregate of 2,121,460 non-transferable broker warrants, each exercisable to acquire one common share of the Company at a price of $0.35 per common share for a period of 24 months following the closing of the Offering.
