Cabaçal DFS Economics: USD 5.4 Billion Life-of-Mine Revenue and Sub-One-Year Payback

The Cabaçal DFS, announced on 22 September 2026, outlined base case life-of-mine total revenue of USD 5.4 billion and after-tax free cash flow of USD 2.9 billion, using price assumptions of USD 3,570 per ounce of gold, USD 5.03 per pound of copper, and USD 50.17 per ounce of silver. Life-of-mine all-in sustaining costs are estimated at USD 1,056 per ounce of gold equivalent. In the first five production years, the project is expected to average 183,526 ounces of gold equivalent annually at an AISC of USD 715 per ounce AuEq, with average annual after-tax free cash flow of USD 413.8 million. The mineral reserve estimate stands at 56.04 million tonnes at 0.61 g/t gold, 0.35% copper, and 1.33 g/t silver.

AFRY Appointed EPCM Contractor and USD 30.9 Million Pre-Construction Contracts Committed

Following the quarter end, Meridian appointed AFRY as EPCM contractor for Cabaçal following an assessment process that included extensive technical due diligence. The company also committed to contracts totalling USD 30.9 million covering pre-construction investments across multiple fronts, including the EPCM contract itself, power transformers, off-site civil infrastructure such as bridges and road upgrades, a SAG mill, Jameson Cells, and an IsaMill. The installation licence for structures along the 138 kV power line route was also secured during the quarter, representing a material regulatory milestone as the project advances towards a final investment decision.

Over Twenty Debt Financing Proposals Received, Several Exceeding USD 400 Million

Post quarter end, Meridian completed an initial project finance outreach programme and received over twenty indicative financing proposals. The announcement states that several parties submitted fully financed indicative proposals of USD 400 million, covering project debt, cost overrun funding, any required equity contribution, and offtake and marketing services. The company is assessing the proposals to generate a shortlist of preferred bidders for detailed negotiations. Investors may be watching the pace of this financing process closely, as selection of a funding partner is a critical step before a final investment decision on what the company describes as the first new producing copper-gold mine in the broader Cabaçal district can be taken.

FTSE 250 Inclusion and Santa Helena Discovery Broaden Meridian's Investment Profile

Meridian was included in the FTSE 250 Index effective 1 October 2026 and was added to the VanEck Junior Gold Miners ETF (GDXJ) effective the close of markets on 18 September 2026, broadening its institutional investor base. At the Santa Helena area within the Cabaçal VMS Belt in Mato Grosso, the company announced the discovery of multiple stacked layers of Au-Cu-Ag and Zn-Pb VMS mineralisation, further extending known mineralisation limits. These developments alongside the DFS reinforce the company's stated Cabaçal Hub strategy, which targets regional-scale exploration across the Cabaçal VMS Belt to support potential long-term expansion beyond the initial project scope.
