TROILUS RECEIVES US$850 MILLION CREDIT-APPROVED DEBT COMMITMENT LETTER FOR THE TROILUS GOLD-COPPER PROJECT

Troilus Mining Corp. has received a credit-approved commitment letter from KfW IPEX-Bank and Societe Generale to underwrite a total of $850-million (U.S.) in debt financing to support the development of its Troilus gold-copper project in Quebec, Canada. This commitment forms part of a planned total anticipated $1.1-billion (U.S.) debt financing package, which includes a proposed $250-million (U.S.) contribution from Export Development Canada (EDC) that remains subject to EDC's final approvals.

The commitment letter represents a major advancement under the company's previously announced debt financing mandate (see May 5, 2026, press release), moving a substantial portion of the proposed debt package from mandate to credit-approved underwriting commitments. The approvals follow extensive technical, environmental, social and financial due diligence by the lenders and mark an important step toward a fully financed construction decision.

Justin Reid, chief executive officer of Troilus, commented: "These credit approvals represent one of the most significant financing milestones in Troilus's development to date. The underwriting commitments from KfW IPEX-Bank and Societe Generale reflect the depth of work undertaken to establish the project's technical and economic foundations and advance our execution plan. With $850-million (U.S.) in credit-approved commitments, we have taken a substantial step toward assembling the funding required to build Troilus. Our focus is now on completing the broader financing package to reach a final investment decision and financial close, while advancing permitting, detailed engineering and procurement to support construction readiness."

Debt financing structure and terms

The commitments from KfW IPEX-Bank and Societe Generale (together, the commercial lenders) comprise senior secured project finance facilities expected to form a cornerstone of the project's overall financing package. The commitment letter is subject to various conditions precedent, including, but not limited to, receiving debt commitments for the total $1.1-billion (U.S.) facility, receiving approvals from each applicable export credit agency, finalization of continuing diligence, execution of definitive documents and support arrangements, there being no material adverse change, and receipt of all required regulatory approvals, among other conditions.

Structured with anticipated support from European export credit agencies, the debt facilities feature competitive interest margins consistent with export credit-backed project financings involving leading international lenders and sovereign support. The proposed structure combines attractive pricing with an extended repayment profile, providing a cost-effective source of capital aligned with the project's development and operating requirements.

The debt facilities include up to a three-year repayment grace period during construction, followed by a sculpted repayment profile over a notional 10-year period aligned with expected cash flow generation. Final terms and further details are expected to be disclosed upon execution of definitive financing documentation.

EDC, one of the project's three mandated lead arrangers alongside the commercial lenders, continues to advance its approval process for a proposed $250-million (U.S.) financing contribution. If approved, this contribution would bring total credit-approved debt commitments to $1.1-billion (U.S.). Troilus is also working with the participating European export credit agencies on the remaining approvals and support arrangements for the broader debt financing package.

The project represents a significant opportunity to expand Canada's copper and gold exports, strengthen long-term supply relationships with trusted European trading partners, and deliver lasting economic benefits for Quebec and Canada. As a mandated lead arranger, EDC is working closely with the lending syndicate and participating European export credit agencies to advance the financing while continuing to work toward its final approvals.

Advancing toward financial close

Building on these commitments, Troilus and its project finance adviser, Auramet International Inc., are focused on finalizing definitive facility agreements, completing the broader financing package and satisfying the various conditions and completion requirements to reach a final investment decision and financial close.
