Aura Signed the Agreement to Relocate Road at Borborema Mine, Unlocking an additional 670 Koz of gold in Mineral Reserves, totaling 1.5 Moz

Executive Summary

• Aura Minerals signed a cooperation agreement with Brazil’s DNIT to relocate the federal road intersecting the Borborema mine, enabling immediate conversion of a large portion of Indicated Resources into Probable Reserves.
• The updated technical report increases Borborema’s Proven & Probable Reserve base by 82 %, now totaling ≈1.5 Moz Au (40.7 Mt @ 1.13 g/t).
• Project economics improve markedly: NPV rises to US$612.5 M and after‑tax IRR to 42.8 % based on a gold price of US$2,274/oz; LOM is extended to 20.5 years with average annual production of 65 koz Au.

Key Details

• Cooperation Agreement: Aura & DNIT will relocate the federal road (BR‑226) that currently crosses the mine, removing a key constraint on pit expansion.
• Reserve Increase: Probable reserves now 40.7 Mt @ 1.13 g/t Au = 1,479 koz Au (up 82 % from prior study).
• Life‑of‑Mine (LOM): 20 years + 5 months; weighted average annual production ≈65 koz Au.
• Economic Highlights:
• NPV (pre‑tax) US$612.5 M (previously US$182 M).
• After‑tax IRR 42.8 % using gold price US$2,274/oz and exchange rate BRL 5.70/USD.
• Technical Methodology: SRK block model built with Ordinary Kriging; nested grade shells at 0.2, 0.5, 1.0 g/t Au; oxidation boundary from 2012 Crusader model; pit design uses gold price US$1,472/oz, mining cost US$2.40‑3.20/t, processing cost US$14.82/t, G&A US$2.8 M/a, sustaining cost US$0.62/t.
• Mining Parameters:
• Plant capacity 2.0 Mtpa; total material movement ≈16 Mtpa.
• Stripping ratio 5.13:1 (waste:ore).
• Total ore mined over LOM 40.69 Mt @ 1.13 g/t Au; waste 224.7 Mt.
• Infrastructure: Road bypass (BR‑226) and high‑voltage transmission line limit pit expansion northward; road relocation removes southern constraint.
• Qualified Persons: Erik Ronald (SRK), Bruno Yoshida Tomaselli (Deswik), Homero Delboni Jr., Farshid Ghazanfari reviewed technical content.
• Forward Outlook: New Resources & Reserves report expected by end of Q1 2026 concurrent with 20‑F filing; ongoing exploration to expand strike and depth extensions.

Notable Quotes

“This agreement is a major milestone that significantly accelerates value creation at Borborema… With the updated reserve now at 1.5 million ounces — 82 % larger than our previous feasibility study — we are immediately advancing engineering and water‑access solutions to increase capacity, while progressing the road relocation.” – Rodrigo Barbosa, President & CEO
