G Mining Ventures forecasts gold output at its Tocantinzinho gold mine to rise from 160,000–190,000 ounces in 2026 to 200,000–235,000 ounces in 2027, representing a roughly 25% increase at the midpoint. Production in 2026 is weighted 62% toward the second half as higher-grade Phase 2 ore becomes available. Cash operating costs are projected at $736–$865 per ounce in 2026, improving to $633–$743 in 2027, while all-in sustaining costs (AISC) are expected to decline from $1,230–$1,444 per ounce in 2026 to $977–$1,146 per ounce in 2027. These figures assume a realized gold price of $4,000/oz and exchange rates of BRL/USD 5.55 and CAD/USD 1.40.

For 2026, sustaining capital spending at Tocantinzinho is estimated at $69–$81 million, including $31–$36 million of waste-stripping. Plant upgrades, equipment replacement and tailings management account for the balance. Growth capital for the Oko West project in Guyana is budgeted at $514–$568 million as construction ramps up, with major equipment deliveries and process plant works underway. In 2027, sustaining capital at Tocantinzinho will range between $62–$74 million while non-sustaining expenditures—primarily Oko West development—are set at $217–$240 million as the project moves into commissioning and pre-production stages.

The Corporation plans its largest exploration program ever in 2026 with a $42–$50 million budget: $21 million at the Gurupi greenfields project, $16 million at Oko West and $9 million at Tocantinzinho. At Tocantinzinho, auger drills and soil geochemistry will target new prospects. At Oko West, follow-up and infill drilling will focus on high-grade shoots, supporting a mid-2027 production start. Gurupi expenditure will advance a Preliminary Economic Assessment scheduled for second-half 2026. Engineering at Oko West is 60% complete, and $423 million—or 44% of upfront capital—has been committed to date.
