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

The Masbate Mine in the Philippines had a record year in 2021, producing an annual record of 222,227 ounces of gold, near the upper end of its revised guidance range (of between 215,000 - 225,000 ounces) and exceeding the upper end of its original guidance range (of between 200,000 - 210,000 ounces), due to higher than budgeted mill recoveries (11% above budget), partially offset by lower than budgeted mill throughput (5% below budget). In addition, Masbate's 2021 annual gold production was 9% (17,528 ounces) higher compared to 2020, mainly due to higher mined ore grades as a result of mining through higher-grade zones of the Main Vein and Montana pits in 2021. 

For full-year 2021, Masbate's cash operating costs were $682 per ounce produced ($660 per ounce sold), within its guidance range (of between $650 - $690 per ounce). Masbate's higher than budgeted production largely offset the impact of higher than budgeted mining and processing costs in 2021 (resulting mainly from inflation driven higher diesel and HFO prices). Compared to 2020, Masbate's cash operating costs were $53 per ounce produced (8%) higher, mainly due to higher fuel prices, partially offset by higher production in 2021. 

Masbate's AISC for the full-year 2021 were $914 per ounce sold (2020 - $985 per ounce sold), $41 per ounce (4%) below the lower end of its guidance range (of between $955 - $995 per ounce). This was attributable to higher than budgeted gold ounces sold and realized gains on fuel derivatives in 2021, partially offset by higher than budgeted cash operating costs discussed above. 

The Masbate Mine is expected to produce between 205,000 - 215,000 ounces of gold in 2022 at cash operating costs of between $740 - $780 per ounce and AISC of between $1,070 - $1,110 per ounce. Masbate's gold production is scheduled to be relatively consistent throughout 2022. Approximately 60% of the budgeted increase in Masbate's AISC for 2022 (compared to 2021 guidance of between $955 - $995 per ounce) is driven by inflation, including higher budgeted fuel and consumable costs. The remainder of the increase is driven mainly by higher sustaining capital expenditures including fleet rebuilds and the planned addition of a powerhouse plant generator budgeted for approximately $10 million.

1. Mineral Resources have been classified using the CIM Standards. Mineral Resources are reported 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. Please see heading “− Property Description, Location, and Access” above for a further discussion of the foregoing.
4. The Qualified Person for the resource estimate is Tom Garagan, P.Geo., our Senior Vice President, Exploration.
5. The Qualified Person for the stockpile estimate is Kevin Pemberton, P.E., our Chief Mine Planning Engineer.
6. Mineral Resource estimates assume an open pit mining method, gold price of US$1,800/oz, modeled metallurgical recovery (resulting in average metallurgical recoveries by resource area that range from 57–85%), and operating cost estimates of US$1.42–US$1.68/t mined (mining), US$11.33/t processed (processing) and US$2.20–US$3.70/t processed (general and administrative).
7. Mineral Resources are reported at an average cut-off grade of 0.37 g/t Au.
8. North and South designations refer to locations north and south of the Guinobatan River, respectively.
