• A total of 324 employees and contractors are currently on site on the construction project (excluding the off-site engineering team and Cabral's in-country exploration and administrative team), 100% of employees and contractors are Brazilian and approximately 42% are from the state of Para

• In-fill drilling of the MG oxide starter pit (first 12 months) is complete, with results supporting the earlier Updated PFS results that were based on wider space drilling

Alan Carter, Cabral's President and CEO, commented, "Construction of our Phase 1 gold-in-oxide heap leach project at Cuiú Cuiú continues to progress and remains on budget and on schedule for commercial gold production during the fourth quarter of this year. The erection of both the dry and wet plant processing facilities are now in progress and the new 160 person mine camp and project offices were commissioned successfully in early April. Overall procurement of equipment for all major plant equipment is now complete, and the adsorption, desorption, and recovery ("ADR") plant is in transit to site. The excellent progress on site has resulted in the plant commissioning schedule being brought forward and is now planned to commence in June 2026. All this has been achieved by the owners' team and contractors having worked a total of 255,960 hours with zero lost time incidents so far during 2026."

Cuiú Cuiú Construction Update

Detailed Engineering

Project engineering has focused on the final design and construction execution for the Heap Leach pads.

Major recent priorities included;

• A review of the piping and instrumentation diagrams ("P&ID's") and detailed design for the plant with a specific focus on the systems downstream of the heap leach pads
• Geotechnical studies and evaluations to support the design of Spent Ore Pile and Waste Rock facilities
• A review of the final design drawings and planned execution for the construction of the Heap Leach Pads (Q2, 2026)

Procurement and Delivery

Overall procurement of equipment for all major plant equipment is now complete, and all items required to commence erection are on site and available to the construction team.

The adsorption, desorption, and recovery ("ADR") plant was successfully dry commissioned in stages at Como Engineering in Perth, Australia. It was then disassembled and packed in shipping containers for transportation to the site. The containers departed Fremantle Port on April 25, and are expected to arrive in Brazil on schedule in late May.

Components of the mineral Sizer that were sourced from Germany are expected to arrive in Brazil in the coming days, with the last of these due to arrive on May 5.

All steel structures and components required for the conveyor systems are now on site and available for plant erection expected in the coming months.

The materials required to commence the construction of the Heap Leach pads and water management and collection ponds, such as HDPE pipes and liners, are on site.

Expenditures and schedule continue to track 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 new mine camp and project offices were commissioned successfully in early April, with most of the new accommodation now occupied by the project team and the new project office fully operational (Figures 1 and 2).

The delivery on schedule of the new accommodation and offices was an important milestone in that it improved the team's operational flexibility and addressed the capacity limitations imposed on the project due to the need to share the original Cuiú Cuiú camp with the growing exploration team. The new accommodation facilities have an increased and final capacity of 160 employees and contractors, while the main project office has the capacity to accommodate 40 staff.

During April, the project reached an important milestone of completing the construction of all major earthworks and civil foundations (including plant foundations, pad layout, and pond excavations). This concludes the ground preparation and foundations ("in ground") phase for the project, supporting the transition of activity to the plant erection and equipment installation ("above ground") phase. Our construction team successfully navigated this critical in-ground phase during the height of the wet period in spite of the difficult conditions. This bodes well for mining in wet conditions and may lead to productivity levels exceeding the conservative metrics of the Updated PFS.

Construction of the ore processing section and the dry circuit of the plant is well underway, with key structures beginning to take shape (Figure 3).

Mining and Resource update

A detailed infill drilling campaign focusing on the first 9 months of production at the MG gold deposit has been completed. Preliminary results from this program were recently reported and were in line with expectations (see press release dated April 7, 2026). The results from these infill drill holes will be used to generate a revised reserve estimate for MG and an updated mine plan.

Preparation required to commence mining is progressing to plan, with mobilization of the mining fleet planned for the coming weeks.

Commissioning

Cabral has engaged Strategic Metallurgy Pty Ltd to oversee and manage the commissioning of the processing plant (ROM pad to ADR plant), with Como Engineering retaining the responsibility for final on-site commissioning of the ADR plant. The commissioning program is likely to take place in 2 phases.

The first phase will focus on the dry circuit, ore leaching on the pads, and the build up of gold inventory (i.e. gold tenor in the pregnant solution) and is planned to commence in June, 2026. This is significantly earlier than previously expected, adopting the "as early as possible" approach, which provides extra time and flexibility to commission the plant in time for planned commercial production in early Q4, 2026.

The second phase will include processing of the pregnant solution, extracting gold through the carbon columns, and producing dore from the ADR plant. The timing of this will be dictated by the progress of the first phase but is currently planned for later in Q3, 2026.

Project Development Timeline

The Project remains on track and on budget for plant commissioning in Q3, 2026, and commercial production in Q4 2026 (Table 1).
