Bond guarantees expected to release approximately US$42 million of cash reclamation bond collateral to Silver Bow Mining; US$5 million pre-bridge financing to be funded within five business days

BUTTE, Mont. -- (Business Wire)

Silver Bow Mining Corp. (NYSE American: SBMT) ("Silver Bow Mining" or the "Company") is pleased to announce that it has signed a non-binding term sheet (the "Term Sheet") with Ocean Partners UK Limited ("Ocean Partners") for an integrated funding, credit support, and offtake package with an aggregate total of approximately US$88 million.

The funding package contemplates a US$40 million concentrate prepayment facility linked to ten-year zinc and lead concentrate offtake agreements for the Company’s Rainbow Block Project in Butte, Montana (the “Rainbow Block”) and the to-be acquired Montana Tunnels Mine (the “Montana Tunnels Mine”) within the Jefferson County Metallurgical Complex (the “Complex”) (collectively, the Properties), approximately US$43.1 million of reclamation bond guarantees at the Rainbow Block and Montana Tunnels Mine, and a US$5 million lead in a future Silver Bow Mining equity investment. A binding US$5 million pre-closing bridge note, to be funded within five business days of signing, forms part of, and will be credited against, the first tranche of the prepayment facility.

The contemplated zinc and lead concentrate offtake agreements would cover concentrates attributable to the Rainbow Block, ores from outside the M-Pit at the Montana Tunnels Mine and one-third of concentrate from ores from the M-Pit at the Montana Tunnels Mine. The Company previously entered into an agreement to acquire the Complex and is targeting final closing of the acquisition (“Final Closing”) in the fourth quarter of 2026, subject to the closing conditions, as described below.

Highlights

• Approximately US$88 million in total funding and credit support. Funding from a single strategic counterparty, Ocean Partners, structured to fund the restart of the Rainbow Block, the refurbishment of the Complex and working capital, without production-timing covenants.
• Approximately US$42 million of cash to be released to the Company. Ocean Partners would provide guarantees supporting replacement surety bonds of up to US$43.1 million. Subject to acceptable terms and approvals, the replacement bonds would be expected to release US$40.9 million currently posted as a cash reclamation bond for the Complex and approximately US$1.1 million of cash collateral currently supporting the Rainbow Block US$2.19 million surety bond.
• Butte reclamation bond also guaranteed. Ocean Partners would provide a guarantee supporting the Company’s approximately US$2.19 million Rainbow Block reclamation bond.
• US$40 million concentrate prepayment facility in three tranches: US$10 million at initial closing of the Facility; US$20 million on a board resolution approving a restart or refurbishment program at either the Properties; and US$10 million at the Company's option after three consecutive months of concentrate deliveries under any of the concentrates contracts. No production-timing covenants; repayment principally by set-off against concentrate deliveries.
• US$5 million pre-bridge financing. As part of the US$40 million concentration prepayment facility, Ocean Partners is expected to fund a US$5 million pre-closing bridge within five business days after execution of the Term Sheet and short-form bridge note. The bridge would be credited against the initial US$10 million tranche at initial closing of the Facility.
• US$5 million lead investment in future equity investment. Ocean Partners will agree to act as lead investor, if and when, the Company conducts its next round of equity financing on the same terms as other investors.
• Ten-year offtake agreements with flexibility preserved. Ocean Partners would purchase 100% of any future potential zinc and lead concentrates attributable to the Rainbow Block, 100% of any future potential zinc and lead concentrates attributable to ores from outside the M-Pit at Montana Tunnels and one-third of future potential zinc and lead concentrates from inside the M-Pit at Montana Tunnels on benchmark-linked terms with no minimum tonnages and no take-or-pay. The Company retains priced rights to terminate the offtake contracts at any time, before or after production, and these rights survive a change of control of the Company.
• Junior to future project debt. The Ocean Partners financing is structured to rank subordinate to future senior project debt financing for both the Rainbow Block and the Complex, preserving the Company's ability to put conventional project financing in place as the Properties advance.
• Definitive documentation targeted concurrently with Final Closing of the acquisition of the Complex, which the Company is targeting for the fourth quarter of 2026.

“This proposed Ocean Partners funding and offtake package is designed to strengthen Silver Bow Mining’s liquidity and financial flexibility as we advance the Rainbow Block Project and work toward completing the acquisition of the Jefferson County Metallurgical Complex," said Travis Naugle, Chairman and Chief Executive Officer. "The release of roughly US$42 million of cash from behind the reclamation bonds at the Complex and Rainbow Block, together with the US$40 million concentrate prepayment facility that carries no production deadlines, would put the Company in a strong position heading into Final Closing on the Complex. It would also provide us the balance sheet to advance the high-grade Rainbow Block through its next technical, permitting and strategic planning steps on our own timetable. Once this package is in place, we do not envision any short-term need for equity financing as we advance these efforts. We intend to preserve the Company's flexibility throughout, including conditional rights to exit the proposed offtake agreements, and we look forward to working with Ocean Partners and their smelter relationships as we continue to explore these Montana assets and move towards development decisions."

"Silver Bow Mining is advancing two significant historic Montana zinc-lead-silver assets, and we are pleased to support the Company with a flexible financing structure linked to future concentrate deliveries," said Brent Omland, Chief Executive Officer of Ocean Partners. "The contemplated prepayment facility and bond guarantees would provide the Company the balance sheet to advance the Properties, while a ten-year offtake for Butte and Montana Tunnels concentrates gives us a long-term, high-quality US-origin supply to place with our smelter partners. We look forward to a long relationship with Travis and the Silver Bow Mining team."

Summary of the Term Sheet

The contemplated US$40 million concentrate prepayment facility consists of: (i) Tranche A of US$10 million, available after satisfaction of the conditions precedent, with the US$5 million pre-closing bridge credited against that amount; (ii) Tranche B of US$20 million, available following delivery to Ocean Partners of a resolution of the board of directors of Silver Bow Mining approving a restart or refurbishment program at either the Rainbow Block or Montana Tunnels; and (iii) Tranche C of US$10 million, available at Silver Bow Mining's option after concentrate deliveries under the applicable offtake arrangements have occurred in each of three consecutive months.

Under the ten-year offtake contracts, Ocean Partners would purchase Rainbow Block and Montana Tunnels non-M-Pit zinc and lead concentrates and one-third of Montana Tunnels M-Pit zinc and lead concentrates on benchmark-linked commercial terms, with no minimum annual tonnages and no take-or-pay obligation. The Company would retain sole discretion over mine plans, sequencing and care-and-maintenance decisions, and has negotiated priced rights to terminate the offtake contracts, for either property, at any time before or after production. Those rights are exercisable by the Company or by any acquirer of the Company or of either property, and a change of control of the Company will not be an event of default under the arrangements. Ocean Partners would hold a right of first offer over the offtake of other concentrates, ores and products from the Rainbow Block and Montana Tunnels, as well as future prepayment, streaming or other offtake-linked funding associated with the Properties.

The concentrate prepayment facility would bear interest at 12-month SOFR plus 6.75% per annum, payable monthly, with a 1.0% arrangement fee deducted from each draw. The principal repayment route would be set-off against net amounts payable for concentrate deliveries. If deliveries are not sufficient, the applicable amounts would be repaid in cash under the agreed amortization schedules. Tranches A and C would have final maturities 36 months after their respective drawdowns. Tranche B would amortize over 24 months after its amortization start date, as defined in the Term Sheet. Silver Bow Mining may prepay at par plus a 1.0% early repayment fee.

The US$5 million pre-closing bridge would bear the same pricing as the contemplated facility and would be supported by a corporate obligation of Silver Bow Mining and an assignment by way of security of Silver Bow Mining's rights under the secured note and acquisition agreement relating to the Jefferson County Metallurgical Complex. If Final Closing of the acquisition of the Complex does not occur, the bridge would become repayable on the long-stop date specified in the bridge note, contemplated to by March 31, 2027.

Ocean Partners would guarantee a surety bond of up to US$40.9 million covering the reclamation obligations of the Complex on a zero cash-collateral basis and a guarantee of approximately US$2.19 million for the current Rainbow Block reclamation bond. On placement of the guaranteed bond and its acceptance by the Montana Department of Environmental Quality ("DEQ"), the existing cash reclamation bond of approximately US$40.9 million associated with the Complex and approximately US$1.1 million of Company’s current US$2.19 million reclamation bond for the Rainbow Block will be released to the Company. The guarantees would have a 60-month term and carry a fee of 3.0% per annum on amounts actually guaranteed, payable at Silver Bow Mining's option in cash, shares or warrants, subject to applicable securities-law and stock-exchange requirements. At the end of the applicable term, Silver Bow Mining would be required to replace the guarantee or provide cash collateral for the relevant bond unless otherwise agreed.

Separately, Ocean Partners would agree to act as lead investor, with a US$5 million commitment, if and when Silver Bow Mining elects to undertake an equity financing within the period specified in the definitive documents. Silver Bow Mining is not obligated to undertake an equity financing, and any investment would be subject to applicable securities-law and stock-exchange requirements.

Further details, including the security package and the terms of the Company’s termination and buy-out rights, will be disclosed if and when the definitive agreements are finalized and executed.

Timing, Conditions, and Binding Effect

The parties will target signing of definitive agreements concurrently with, or as soon as practicable after, Final Closing of the Company's previously announced acquisition of the Complex, which the Company is targeting for the fourth quarter of 2026, with the bond guarantee facility and the first tranche of the prepayment facility available at that time. Completion is subject to customary conditions, including negotiation and execution of definitive agreements, Final Closing of the Complex acquisition, security documentation, satisfactory due diligence, approval of the board of directors of Ocean Partners and the Company, and surety terms and DEQ acceptance of the guaranteed surety bond satisfactory to the Company.

Completion of the Company's acquisition of the Complex remains subject to the conditions described in the Company's news release of August 24, 2026 announcing the definitive agreement, including approval of the shareholders of Silver Bow Mining, approval of the NYSE American LLC, certain other governmental approvals, if deemed necessary, and the absence of material adverse changes or litigation materially affecting the acquired assets. There can be no assurance that Final Closing will occur within the targeted timeframe or at all.

Other than the pre-bridge financing note and customary provisions relating to exclusivity, expenses, communications and governing law, the Term Sheet is non-binding and its terms remain subject to change in the course of negotiating the definitive agreements. There can be no assurance that definitive agreements will be entered into or that the transactions described in this news release will be completed on the terms described or at all. The Company will file a Current Report on Form 8-K and issue a further news release if and when the definitive agreements are executed and delivered.
