Masbate Mine – The Philippines (1)

The Masbate Gold Project is located on Masbate Island in the Philippines. The Masbate Mine is located approximately 360 km southeast of the country's capital, Manila.

B2Gold acquired its interest in Masbate through its acquisition of CGA Mining Limited in January 2013.

The Masbate Mine is expected to produce between 170,000 and 190,000 ounces of gold in 2024 at cash operating costs of between $945 and $1,005 per ounce and all-in sustaining costs of between $1,300 and $1,360 per ounce. Gold production is scheduled to be relatively consistent throughout 2024. For 2024, Masbate is expected to process 7.9 million tonnes of ore at an average grade of 0.93 g/t with a process gold recovery of 76.0%. Mill feed will be a blend of mined fresh ore and low-grade ore stockpiles.

Capital expenditures for 2024 at Masbate are expected to total $49 million, of which approximately $33 million is classified as sustaining capital expenditures and $16 million is classified as non-sustaining capital expenditures. Sustaining capital expenditures are anticipated to include $16 million for mining and mobile equipment replacement and rebuilds, $6 million for deferred stripping, $6 million for process plant, and $3 million for tailings storage facility expansion. Non-sustaining capital expenditures are anticipated to include $16 million for land acquisition and development.

  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.

  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.

  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.
