Vancouver, March 5, 2026 - Cabral Gold Inc. (TSXV: CBR) (OTCQX: CBGZF) ("Cabral" or the "Company") is pleased to provide a construction update regarding its Phase 1 gold-in-oxide heap leach project at the Cuiú Cuiú Gold District, Brazil.

Highlights

• Construction activity for the Phase 1 gold-in-oxide heap leach construction project is now 54% complete, with 71% of project costs committed under contract

• The project remains on budget and on schedule for plant commissioning in Q3, 2026 and commercial production in Q4 2026

• Detailed engineering is on track, and procurement of major plant equipment is now over 90% complete, with the procurement of the remaining equipment to be finalized later this month.

• The Owners team and Contractors have so far worked a total of 93,625 hours during 2026 with a Lost Time Incident ("LTI") rate of zero

• A total of 283 employees and contractors are currently on site on the construction project (excluding the off-site Ausenco Brazil engineering team and members of the owners' team as well as Cabral's exploration team), 100% of employees and contractors are Brazilian and 70% are from the state of Para

• In-fill drilling of the MG oxide starter pit (first 12 months) is 75% complete and once completed will feed into a detailed mine design which provides the mine plan for the commencement of mining activities in mid-2026

Alan Carter, Cabral's President and CEO, commented, "Our Construction team continues to make excellent progress in executing on the 12-month construction program for our Phase 1 gold-in-oxide heap leach project at Cuiú Cuiú. Our team has demonstrated resilience and strong technical capability in successfully dealing with the challenges encountered to date. We have put behind us the uncertainty normally associated with significant earthworks of a construction project, and we are now focused on above-ground construction and plant erection, which is less dependent on weather conditions. The execution of the project plan is proceeding on budget and to schedule, targeting commissioning of the plant in the third quarter of 2026, followed by commercial production at Cuiú Cuiú in the fourth quarter of 2026."

Cuiú Cuiú Construction Update

Detailed Engineering

Project engineering and construction execution drawings continue ahead of plan ensuring these activities are unlikely to impact the critical path.

Major current priorities include;

• P&IDs and detailed design for wet systems (post Heap Leach Pads)
• Geotechnical study and evaluation in support of design of Spent Ore Pile and Waste Rock facilities
• Finalise design and execution drawings in preparation for the construction of the Heap Leach Pads (quarter 2, 2026)

Procurement and Delivery

Overall procurement of equipment for all major plant equipment is over 90% complete. Notable long-lead items currently being manufactured include the adsorption, desorption, and recovery ("ADR") plant, the mineral sizer, and the various conveyor systems. The ADR plant is in the final assembly stage at Como Engineering in Perth, Australia (Figure 1). After a dry commissioning program in March, the plant will be disassembled and packed in shipping containers for transportation to the site.

Expenditures and schedule are tracking in line with the Pre-Feasibility Study with an effective date of July 29, 2025 (filed under Cabral Gold's profile on Sedar, entitled "Pre-Feasibility Study - NI 43-101 Technical Report, Cabral Gold Inc.").

Infrastructure Improvements and Construction

The area for the permanent mine camp has been cleared and leveled, and construction began in January 2026. The mine camp and project offices will be located within the secured operations area and alongside the new dedicated private airstrip. The new accommodation facilities will have capacity for 136 employees and contractors, and they remain on schedule for completion by the end of March 2026 (Figure 3).

Earthworks on the production plateau are now 95% complete, as are most of the concrete foundations required to support the process equipment due on site in the coming months. The final water and solution storage ponds are currently nearing completion (Figure 4). This critical phase of the project was completed on time and within the allocated budget.
