About Masbate

Masbate is considered to be an example of a low sulphidation epithermal gold deposit. The gold deposits currently being mined at Masbate are centered on a 5 - 7 km wide northwest-to-southeast oriented mineralized volcanic block which is bounded by two interpreted northwest-trending fault zones.

Masbate is a conventional open pit operation. Based on the current life of mine, mining activities are expected to end in 2027 while Mineral Reserve stockpile processing is expected to continue into 2033.

Notes
  1. Mineral Resources have been classified using the CIM Standards. Mineral Resources are reported in situ or in stockpiles inclusive of those Mineral Resources that have been modified to Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
  2. All tonnage, grade and contained metal content estimates have been rounded; rounding may result in apparent summation differences between tonnes, grade, and contained metal content.
  3. Mineral Resources are reported on a 100% project basis. Pursuant to the ore sales and purchase agreement between Filminera and PGPRC, our wholly-owned subsidiary, PGPRC has the right to purchase all ore from the Masbate Gold Project. We have a 40% interest in Filminera, which owns the majority of the Masbate Gold Project tenements, and the remaining 60% is owned by Zoom, a Philippine shareholder company.
  4. The Qualified Person for the resource estimate is Michael Johnson, P.Geo., our Technical Services Manager.
  5. The Qualified Person for the stockpile estimate is Peter Montano, our Vice President, Projects.
  6. The Mineral Resource estimate for the Masbate Gold Project accounts for mining depletion as of December 31, 2023. The Mineral Resource estimate has an effective date of December 31, 2023.
  7. Mineral Resource estimates assume an open pit mining method.
  8. Mineral Resources are reported within a conceptual open pit based on a gold price of US$1,850/oz, modeled metallurgical recovery (resulting in average metallurgical recoveries by resource area that range from 62%-89%), and operating cost estimates of US$1.52–US$2.01/t mined (mining), US$14.63/t processed (processing) and US$2.39–US$3.90/t processed (general and administrative).
  9. Mineral Resources are reported at an average cut-off grade of 0.41 g/t Au.
  10. North and South designations refer to locations north and south of the Guinobatan River, respectively.

Notes
  1. Mineral Reserves have been classified using the CIM Standards, and are reported at the point of delivery to the process plant.
  2. All tonnage, grade and contained metal content estimates have been rounded; rounding may result in apparent summation differences between tonnes, grade, and contained metal content.
  3. Mineral Reserves are reported on a 100% project and attributable basis. Pursuant to the ore sales and purchase agreement between Filminera and PGPRC, our wholly-owned subsidiary, PGPRC has the right to purchase all ore from the Masbate Gold Project. We have a 40% interest in Filminera, which owns the majority of the Masbate Gold Project tenements, and the remaining 60% is owned by Zoom, a Philippine shareholder company.
  4. The Qualified Person for the reserve estimate is Peter Montano, our Vice President, Projects, and a Qualified Person under NI 43-101.
  5. Mineral Reserves are based on a conventional open pit mining method, gold price of US$1,600/oz, modeled metallurgical recovery (resulting in average LoM metallurgical recoveries by pit that range from 60% to 86%), and average base operating cost estimates of US$1.46–US$2.23/t mined (mining), US$14.63/t processed (processing) and US$2.39-3.90/t processed (general and administrative).
  6. Reserve model dilution and ore loss were applied through whole block averaging such that at a 0.45 g/t Au cut-off there is a 2.6% increase in tonnes, a 6.6% reduction in grade, and a 4.1% reduction in ounces when compared to the Mineral Resource model. Mineral Reserves are reported at an assay cut-off grade of 0.47 g/t Au.
  7. North and South designations refer to locations north and south of the Guinobatan River, respectively.

Exploration

The total budget for the Philippines in 2025 is approximately $5 million, of which the Masbate exploration budget is $3 million, including approximately 4,200 meters of drilling. The 2025 exploration program will continue to focus on exploration of new regional targets located south of the main mine infrastructure at Masbate.

An additional $2 million will be allocated to targeting new regional projects in highly prospective areas in the Philippines, leveraging off B2Gold's presence and operation experience in the country.
A total of 2,000 meters is allocated to testing new projects.
