• B2Gold consolidated gold production expected to increase to record levels in 2025: Based on current estimates, consolidated gold production is expected to be between 1,130,000 and 1,260,000 ounces in 2025, driven by a significant increase in gold production from the Fekola Complex, relative to 2024, as a result of the scheduled mining and processing of higher-grade ore from the Fekola and Cardinal pits made accessible by the meaningful stripping campaign that will be undertake throughout 2024, a full year contribution of higher-grade ore from Fekola Regional, and commencement of mining the higher-grade Fekola underground (subject to receipt of necessary permits for Fekola Regional and Fekola underground). In addition, the Goose Project is expected to commence gold production in the first quarter of 2025 and contribute between 220,000 and 260,000 ounces of gold production in calendar year 2025.
  

Update on Off-Site Attack in Mali

On February 15, 2024, the Company reported three fatalities from an off-site armed attack in Mali. Traveling on the national highway under Malian gendarme escort, a bus transporting B2Gold employees from the Fekola Mine to Bamako was involved in an incident when it was attacked approximately 75 km west of Bamako. This tragic event was the result of an armed attack on the employee transport convoy, which included Malian gendarmerie vehicles in front and in the rear of the transport convoy. Unfortunately, as of February 21, 2024, B2Gold deeply regrets to report that a fourth employee has passed away as a result of injuries sustained in the attack. Three employees remain in intensive care and are being treated for their injuries in Bamako. All B2Gold employees traveling on the bus have now been accounted for. B2Gold wishes to express its deepest condolences to the families of the deceased employees and extends its best wishes for a full recovery to all those employees who were injured in the attack.

The attack occurred over 300 km northeast of the Fekola Mine site, along a transport route that has been the focus of increased security presence by the Malian armed forces. Mining and processing activities at the Fekola Mine were not impacted by this incident. The Company is actively engaged with the Malian government on a full investigation into the cause of the attack, and on further improvements to security along the national highway.

Operations

Fekola Mine - Mali

^{(1) Non-IFRS measure. For a description of how these measures are calculated and a reconciliation of these measures to the most directly comparable measures specified, defined or determined under IFRS and presented in the Company's financial statements, refer to "Non-IFRS Measures".}

The Fekola Mine in Mali (owned 80% by the Company and 20% by the State of Mali) was a strong performer in 2023, producing 590,243 ounces of gold, near the mid-point of the annual guidance range of 580,000 to 610,000 ounces. For the year ended December 31, 2023, mill feed grade was 2.13 grams per tonne ("g/t"), mill throughput was a record 9.41 million tonnes, and gold recovery averaged 92.3%. In the fourth quarter of 2023, the Fekola Mine produced 143,010 ounces of gold. During the fourth quarter of 2023, the Fekola processing facilities continued to outperform expectations as a result of continued favourable ore fragmentation and continued optimization of the grinding circuit. For the fourth quarter of 2023, mill feed grade was 1.99 g/t, mill throughput was 2.42 million tonnes, and gold recovery averaged 93.4%. Mined ore tonnage and grade continue to reconcile well with the Fekola resource model.

For the year ended December 31, 2023, the Fekola Mine's cash operating costs (see "Non-IFRS Measures") of $572 per gold ounce produced ($566 per gold ounce sold) were at the lower end of Fekola's guidance range of between $565 and $625 per gold ounce produced. Fekola's cash operating costs for the fourth quarter of 2023 were $605 per gold ounce produced ($646 per gold ounce sold), slightly lower than expected due to higher than anticipated production in the fourth quarter.

All-in sustaining costs (see "Non-IFRS Measures") for the Fekola Mine for the year ended December 31, 2023 were $1,194 per gold ounce sold, near the low end of the revised guidance range of between $1,175 and $1,235 per gold ounce sold, but higher than the original guidance range of between $1,085 and $1,145 per gold ounce sold. All-in sustaining costs for the Fekola Mine for the fourth quarter of 2023 were $1,444 per gold ounce sold.

Capital expenditures for the year ended December 31, 2023, totalled $299 million, primarily consisting of $80 million for deferred stripping, $84 million for mobile equipment purchases and rebuilds, $39 million for tailings storage facility expansion and equipment, $39 million for the development of the Fekola underground mine, $18 million for the expansion of the solar plant, $12 million for site general capital, $12 million for other mining sustaining capital, $10 million for process and power plant, and $5 million for Bantako road construction. Capital expenditures in the fourth quarter of 2023 totalled $88 million, primarily consisting of $24 million for deferred stripping, $18 million for mobile equipment purchases and rebuilds, $16 million for tailings storage facility expansion and equipment, $14 million for the development of the Fekola underground mine, $7 million for the expansion of the solar plant, $5 million site general capital, and $3 million for other mining sustaining capital.

The Fekola Complex is comprised of the Fekola Mine (Medinandi permit hosting the Fekola and Cardinal pits and Fekola underground) and Fekola Regional (Anaconda Area (Bantako, Menankoto, and Bakolobi permits) and the Dandoko permit). The Fekola Complex is expected to produce between 470,000 and 500,000 ounces of gold in 2024 at cash operating costs of between $835 and $895 per ounce and all-in sustaining costs of between $1,420 and $1,480 per ounce. The Fekola Complex's total 2024 gold production is anticipated to decrease relative to 2023, predominantly as a result of the delay in receiving an exploitation license for Fekola Regional from the Government of Mali, delaying the 80,000 to 100,000 ounces that were scheduled in the life of mine plan to be trucked to the Fekola mill and processed in 2024. The contribution of this gold production from Fekola Regional is now assumed to commence at the beginning of 2025. If an exploitation license is received in the first half of 2024, there is potential for 2024 Fekola Complex production to be supplemented with up to 18,000 ounces of higher-grade ore from Fekola Regional.

During the year ended December 31, 2023, the State of Mali introduced a new mining code (the "2023 Mining Code"). Receipt of an exploitation license for Fekola Regional remains outstanding pending finalization of an implementation decree for the new 2023 Mining Code by the State of Mali. B2Gold recently held meetings with representatives of the Government of Mali regarding the 2023 Mining Code. The Government of Mali assisted the Company in clarifying the application of the 2023 Mining Code to existing and future projects in Mali, and also expressed their desire for B2Gold to rapidly progress the development of Fekola Regional and committed to assisting the Company in such development.

The haul road from Bantako North to Fekola is complete and construction of the mining infrastructure (warehouse, workshop, fuel depot, and offices) will be completed in the first quarter of 2024. Mining operations will commence upon receipt of an exploitation license, with initial gold production approximately three months after commencement.

Fekola is expected to process 9.4 million tonnes of ore during 2024 at an average grade of 1.77 g/t gold with a process gold recovery of 90.9%. Gold production is expected to be evenly weighted between the first half of 2024 and the second half of 2024. In the second half of 2024, gold production is expected to be weighted approximately 40% to the third quarter and approximately 60% to the fourth quarter.

The expected increase in Fekola's all-in sustaining costs for 2024 relative to 2023 reflects the expected decrease in production at Fekola in 2024 due to the delay in receiving an exploitation license for Fekola Regional and higher sustaining capital expenditures. Capital expenditures in 2024 at Fekola are expected to total approximately $309 million, of which approximately $202 million is classified as sustaining capital expenditures and $107 million is classified as non-sustaining expenditures. Sustaining capital expenditures are anticipated to include $80 million for deferred stripping, $45 million for ongoing construction of the new tailings storage facility (expected to be completed in the second quarter of 2025), $39 million for new and replacement Fekola mining equipment, including capitalized rebuilds, and $19 million for the expansion of the Fekola solar plant (expected to be completed in the third quarter of 2024). Non-sustaining capital expenditures are anticipated to include $64 million for underground mine development and $43 million for mine development and infrastructure at Fekola Regional.

Masbate Mine - The Philippines

^{(1) Non-IFRS measure. For a description of how these measures are calculated and a reconciliation of these measures to the most directly comparable measures specified, defined or determined under IFRS and presented in the Company's financial statements, refer to "Non-IFRS Measures".}

The Masbate Mine in the Philippines continued its strong operational performance in 2023, producing 193,502 ounces of gold, exceeding the upper end of its guidance range of 170,000 to 190,000 ounces. For the year ended December 31, 2023, mill feed grade was 0.97 g/t, mill throughput was a record 8.30 million tonnes, and gold recovery averaged 74.5%. Gold recoveries for 2023 of 74.5% were in-line with those of 2022. Average 2023 gold recoveries were as expected despite processing a higher percentage of sulphide and transitional ore than planned. Masbate's mill throughput was higher than anticipated in 2023 as a result of continued improvements to optimization of mill operations and blending of mill feed. Mined ore tonnage and grade continue to reconcile well with the Masbate resource model. In the fourth quarter of 2023, Masbate produced 46,490 ounces of gold. Lower ore gold grade during the quarter was offset by higher than expected mill throughput. Fourth quarter 2023 mill feed grade was 0.90 g/t, mill throughput was 2.08 million tonnes, and gold recovery averaged 77.0%.

The Masbate Mine's cash operating costs (see "Non-IFRS Measures") of $859 per gold ounce produced ($844 per gold ounce sold) for the year ended December 31, 2023 were at the low end of the revised guidance range of between $855 and $915 per gold ounce produced and significantly below the original guidance range of between $985 and $1,045 per gold ounce produced. As a result of lower than anticipated diesel and heavy fuel oil costs, Masbate experienced lower than expected mining and processing costs throughout 2023, which with the higher than anticipated gold production, contributed significantly to the lower than expected cash operating costs per gold ounce produced for Masbate for the year ended December 31, 2023. The Masbate Mine's cash operating costs for the fourth quarter of 2023 were $910 per gold ounce produced ($817 per gold ounce sold).

All-in sustaining costs (see "Non-IFRS Measures") for the Masbate Mine were $1,143 per gold ounce sold for the year ended December 31, 2023, below the lower end of the revised guidance range of between $1,155 and $1,215 per gold ounce sold and well below the original guidance range of between $1,370 and $1,430 per gold ounce sold. All-in sustaining costs for the year ended December 31, 2023 were lower than anticipated as a result of higher than expected gold ounces sold, lower than expected cash operating costs as described above, and lower than anticipated sustaining capital expenditures. All-in sustaining costs for the Masbate Mine for the fourth quarter of 2023 were $1,118 per gold ounce sold.

Capital expenditures totalled $30 million in 2023, primarily consisting of mobile equipment rebuilds and purchases of $17 million, $3 million for the completion of a new powerhouse generator and other powerhouse engine rebuilds, $2 million in deferred stripping, $2 million for tailings storage facility projects, and $2 million for capitalized mill maintenance. Capital expenditures for the fourth quarter of 2023 totalled $9 million, primarily consisting of $5 million for mobile equipment rebuilds and purchases, $1 million for capitalized mill maintenance, $1 million for powerhouse rebuilds, and $1 million for the tailings storage facility.

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 mine development.

Otjikoto Mine - Namibia

^{(1) Non-IFRS measure. For a description of how these measures are calculated and a reconciliation of these measures to the most directly comparable measures specified, defined or determined under IFRS and presented in the Company's financial statements, refer to "Non-IFRS Measures".}

The Otjikoto Mine in Namibia, in which the Company holds a 90% interest, had a strong finish to 2023 and produced an annual record of 208,598 ounces of gold, at the upper end of the guidance range of 190,000 to 210,000 ounces, mainly due to improved processed grade as a result of higher-grade ore mined from the Wolfshag underground mine. For the year ended December 31, 2023, mill feed grade was 1.91 g/t, mill throughput was 3.44 million tonnes, and gold recovery averaged 98.6%. In the fourth quarter of 2023, the Otjikoto Mine produced a quarterly record of 81,111 ounces of gold. For the fourth quarter of 2023, mill feed grade was 2.88 g/t, mill throughput was 0.89 million tonnes, and gold recovery averaged 98.5%.

As of the beginning of 2023, the Probable Mineral Reserve estimate for the Wolfshag deposit included 203,000 ounces of gold in 1.1 million tonnes of ore at an average grade of 5.55 g/t gold. Open pit mining operations at the Otjikoto Mine are scheduled to ramp down throughout 2024 and conclude in 2025, while underground mining operations at Wolfshag are expected to continue through 2026. Processing operations will continue through 2031, when economically viable stockpiles are forecast to be exhausted.

On January 31, 2024, the Company announced positive exploration drilling results from the Antelope deposit at the Otjikoto Mine. The Antelope deposit, comprised of the Springbok Zone, the Oryx Zone, and a possible third structure, Impala, subject to further confirmatory drilling, is located approximately 3 km south of the Otjikoto Phase 5 open pit. The Antelope deposit has the potential to be developed as an underground mining operation, which could complement the expected processing of low-grade stockpiles at the Otjikoto mill from 2026 through 2031.

The Otjikoto Mine's cash operating costs (see "Non-IFRS Measures") for the year ended December 31, 2023 were $585 per gold ounce produced ($568 per gold ounce sold), within its revised guidance range of between $545 and $605 per gold ounce produced and below its original guidance range between $590 and $650 per gold ounce produced. Cash operating costs per gold ounce produced for the year ended December 31, 2023 were lower than expectations as a result of higher than expected gold ounces produced and lower operating costs due to a weaker than anticipated Namibian dollar. For the fourth quarter of 2023, the Otjikoto Mine's cash operating costs were $451 per gold ounce produced ($503 per ounce gold sold).

All-in sustaining costs (see "Non-IFRS Measures") for the Otjikoto Mine for the year ended December 31, 2023 were $984 per gold ounce sold, within its revised guidance range of between $950 and $1,010 per ounce sold and well below its original guidance range of between $1,080 and $1,140 per ounce sold. All-in sustaining costs for the year ended December 31, 2023 were below the low end of its original guidance range as a result of higher than anticipated gold ounces sold, lower than expected cash operating costs and lower than anticipated sustaining capital expenditures primarily related to deferred stripping and underground development. All-in sustaining costs for the Otjikoto Mine for the fourth quarter of 2023 were $816 per gold ounce sold.

Capital expenditures totalled $61 million in 2023, primarily consisting of $47 million for deferred stripping for the Otjikoto pit, $10 million for Wolfshag underground development, and $2 million in mobile equipment rebuilds. Capital expenditures for the fourth quarter of 2023 totalled $15 million, primarily consisting of $10 million for deferred stripping for the Otjikoto pit and $3 million for Wolfshag underground development.

The Otjikoto Mine is expected to produce between 180,000 and 200,000 ounces of gold in 2024 at cash operating costs of between $685 and $745 per ounce and all-in sustaining costs of between $960 and $1,020 per ounce. Gold production at Otjikoto is expected to be relatively consistent throughout 2024. For 2024, Otjikoto is expected to process a total of 3.4 million tonnes of ore at an average grade of 1.77 g/t with a process gold recovery of 98.0%. Processed ore will be sourced from the Otjikoto pit and the Wolfshag underground mine, supplemented by existing medium and high-grade ore stockpiles.

Capital expenditures in 2024 at Otjikoto are expected to total $33 million, of which approximately $32 million is classified as sustaining capital expenditures and $1 million is classified as non-sustaining capital expenditures. Sustaining capital expenditures are anticipated to include $32 million for deferred stripping and deferred underground development.

Goose Project Development

On April 19, 2023, the Company completed the acquisition of Sabina Gold & Silver Corp. ("Sabina"), resulting in the Company acquiring Sabina's 100% owned Back River Gold District located in Nunavut, Canada by issuing approximately 216 million common shares of B2Gold as consideration. The Back River Gold District consists of five mineral claims blocks along an 80 km belt.

B2Gold recognizes that respect and collaboration with the Kitikmeot Inuit Association ("KIA") is central to the license to operate in the Back River Gold District and will continue to prioritize developing the project in a manner that recognizes Inuit priorities, addresses concerns, and brings long-term socio-economic benefits to the Kitikmeot Region. B2Gold looks forward to continuing to build on its strong collaboration with the KIA and Kitikmeot Communities.

Construction at the Goose Project continues to progress on track, with the project remaining on schedule to pour first gold in the first quarter of 2025. Concrete and steel works in the mill area to date are progressing ahead of schedule. Exterior cladding of the mill building and truck shop is complete and cladding of the power house will commence in the first quarter of 2024. Enclosure of these buildings has allowed for work to continue through the colder months and remain on schedule. Additionally, the ball mill will be set in place in the first quarter of 2024, approximately four months ahead of schedule, and the focus will switch to piping, electrical, and mechanical systems as materials begin to arrive via the WIR from the MLA. Crews for installation of piping, electrical, and mechanical systems have been mobilized and will work within the enclosed workshops and buildings as the site ramps up to peak 2024 construction season. Progress to date has considerably de-risked the Goose Project as the site ramps up to the peak 2024 construction season.

Following the successful completion of the 2023 sealift, construction of the 163 km WIR between the MLA and the Goose Project is being finalized. The WIR is scheduled to be fully operational by February 23, 2024, transporting all required materials from the MLA to the Goose Project site by the end of April 2024, keeping the Goose Project on schedule to pour first gold in the first quarter of 2025.

After completing a detailed review of the Goose Project design, materials, and construction schedule as part of the 2024 budgeting process, the Company has revised the total construction capital estimate from C$800 million to C$1,050 million. Most of the increase in the construction capital estimate relates to underestimated labour and site operating costs in the feasibility study, along with additional general inflationary impacts on construction materials, consumables, and transportation costs. In addition, a detailed review of the project design has identified deficiencies in project components including power generation and distribution, laboratory, piping, and controls and instrumentation, which are being corrected to deliver a reliable operation. In 2024, B2Gold expects to incur approximately C$280 million in construction capital costs. Future construction cost variance is expected to be minimal as over half of the construction capital costs to be incurred in 2024 are related to labour in order to bring the project close to commissioning by the end of the year, and all major components have been purchased or are under contract. In the fourth quarter of 2023 and post-acquisition to December 31, 2023, the Company incurred $126 million (C$171 million) and $282 million (C$381 million), respectively for construction activities at the Goose Project.

In addition, the net cost of open pit and underground development, deferred stripping, and sustaining capital expenditures to be incurred prior to first gold production is estimated at approximately C$200 million (including approximately C$125 million of direct mining costs related to open pit and underground development). The cost of these initiatives is primarily related to optimization changes in the underground mine plan as a result of switching the underground mining method to long-hole stoping and prioritizing ore from the Umwelt crown pillar area ahead of the zones below. It is anticipated that the increase in underground development costs will be offset during operations through lower sustainable operating costs than could be achieved with the cut-and-fill underground mining method. Additionally, B2Gold has elected to advance open pit mining of the Echo Pit, which is underway and will produce construction fill, stockpile ore, and provide tailings storage capacity. Open pit mining of the Umwelt Pit is expected to commence later in the first quarter of 2024 and will produce much of the commissioning ore as well as future tailings storage. In 2024, B2Gold expects to incur approximately C$170 million in open pit and underground development, deferred stripping, and sustaining capital expenditures.

In 2024, the Company will undertake a buildup of working capital over the Goose Project construction period up to the first quarter of 2025 in order to materially de-risk the execution of the production ramp-up phase and initial years of operation by including 2025 and certain 2026 consumables and sustaining capital equipment on the 2024 sealift. Areas of focus for working capital include: accelerated purchase and additional storage of diesel fuel to manage the requirements for operations in 2025 and part of 2026; critical inventory of consumables and spares for mining and processing to avoid the requirement for air transport; and development of open pit and underground ore stockpiles to provide a consistent and uninterrupted feed to the process plant. The Company estimates that approximately C$205 million of fuel, reagents, and other working capital items will be purchased in 2024 to build up site inventory levels, which will substantially de-risk the project from operational and supply chain disruptions. Post-acquisition to December 31, 2023, $57 million of consumables inventory costs were incurred, including long-term consumables of $44 million.

Fekola Complex Development

Based on B2Gold's preliminary planning, the Anaconda Area could provide selective higher-grade saprolite material (average annual grade of up to 2.2 g/t gold) to be trucked approximately 20 km and fed into the Fekola mill at a rate of up to 1.5 million tonnes per annum. Trucking of selective higher-grade saprolite material from the Anaconda Area to the Fekola mill will increase the ore processed and has the potential to generate approximately 80,000 to 100,000 ounces of gold production per year from Fekola Regional sources. Receipt of a mining permit for the Fekola Regional licenses remains outstanding pending finalization of an implementation decree for the new 2023 Mining Code by the State of Mali. The Company does not currently forecast any production from Fekola Regional in the Company's 2024 guidance, with production now expected to commence at the beginning of 2025. If an exploitation license for Fekola Regional is received in the first half of 2024, there is potential for 2024 Fekola Complex production to be supplemented with up to 18,000 ounces of higher-grade ore from Fekola Regional. In addition, if the Company is successful in discovering additional sulphide ore across the Fekola Complex, the trucking of oxide ore from Fekola Regional to the Fekola mill may potentially be extended. B2Gold recently held meetings with the representatives of the Government of Mali regarding the 2023 Mining Code. The Government of Mali assisted the Company in clarifying the application of the 2023 Mining Code to existing and future projects in Mali, and also expressed their desire for B2Gold to rapidly progress the development of Fekola Regional and committed to assisting the Company in such development.

For the fourth quarter of 2023 and the year ended December 31, 2023, the Company invested $10 million and $56 million respectively, in the development of Fekola Regional (Anaconda Area) saprolite mining including road construction, mine infrastructure, and mining equipment. For 2023, the Company had budgeted a total of $63 million for Fekola Regional development.

Gramalote Project Development

B2Gold's in-house projects team has commenced work on various smaller scale project development plans for the Gramalote Project, with the goal of identifying a higher-return project than the previously contemplated joint venture development plan. Based on the results of the 2022 Gramalote feasibility study, the contemplated larger scale project did not meet the combined investment return thresholds for development by both B2Gold and AngloGold. In 2023, B2Gold completed a detailed review of the Gramalote Project, including the facility size and location, power supply, mining and processing options, tailings design, resettlement, potential construction sequencing, and camp design to identify potential cost savings to develop a smaller scale project. The results of the review allowed the Company to determine the optimal parameters and assumptions for a formal study, which commenced in the fourth quarter of 2023, with the goal of completing a PEA by the end of the second quarter of 2024.

Exploration

B2Gold executed another year of aggressive exploration in 2023 incurring $78 million (including $2 million of target generation costs included in other operating expenses in the Consolidated Statement of Operations) compared to a revised budget of approximately $84 million (original budget of $64 million). Exploration in 2023 was focused predominantly in Mali, other operating mine sites in Namibia and the Philippines, both infill and generative exploration at the Back River Gold District, as well as a continued focus on grassroots targets around the world.

B2Gold is planning another year of extensive exploration in 2024 with a budget of approximately $63 million. A significant focus will be exploration at the Back River Gold District, with the goal of enhancing and growing the significant resource base at the Goose Project and surrounding regional targets. In Namibia, the exploration program at the Otjikoto Mine will be the largest program since 2012, with 39,000 meters of drilling planned to define and expand the recently discovered Antelope deposit. In Mali, the exploration program will be a more strategic search for near-mine, near-surface sources of additional sulphide-related gold mineralization. In the Philippines, the exploration program at Masbate will focus on converting inferred mineral resource areas and expanding the existing open pits. Early stage exploration programs will continue in Finland, the Philippines, and Cote d'Ivoire in 2024. Finally, the search for new joint ventures and strategic investment opportunities will continue, building on existing equity investments in Snowline Gold Corp. and Matador Mining Ltd.

Outlook

Total gold production in 2024 is anticipated to be between 860,000 and 940,000 ounces, including 40,000 to 50,000 ounces of attributable production from Calibre. Production is expected to be relatively consistent throughout 2024, with third quarter production expected to be slightly lower and fourth quarter production expected to be slightly higher. The expected decrease in gold production relative to 2023 is predominantly due to lower production at the Fekola Complex as a result of the delay in receiving an exploitation license for Fekola Regional from the Government of Mali, delaying the 80,000 to 100,000 ounces that were scheduled in the life of mine plan to be trucked to the Fekola mill and processed in 2024. The contribution of this gold production from Fekola Regional is now assumed to commence at the beginning of 2025. The Company's total consolidated cash operating costs for the year (including estimated attributable results for Calibre) are forecast to be between $835 and $895 per gold ounce produced and total consolidated all-in sustaining costs (including estimate attributable results for Calibre) are forecast to be between $1,360 and $1,420 per gold ounce sold. The anticipated increase in the Company's consolidated cash operating costs per ounce for 2024 reflects the processing of lower-grade ore at Fekola in 2024. The total consolidated all-in sustaining costs per ounce for 2024 reflect the final full year of spending on both the new Fekola tailings storage facility and the Fekola solar plant expansion, in addition to the ongoing substantial capitalized stripping campaign planned at Fekola for 2024.

B2Gold consolidated gold production is expected to increase to record levels in 2025. Based on current estimates, consolidated gold production in 2025 is expected to be between 1,130,000 and 1,260,000 ounces, driven by a significant increase in gold production from the Fekola Complex, relative to 2024, as a result of the scheduled mining and processing of higher-grade ore from the Fekola and Cardinal pits made accessible by the meaningful stripping campaign that will be undertaken throughout 2024, a full year contribution of higher-grade ore from Fekola Regional, and commencement of mining from the higher-grade Fekola underground (subject to receipt of necessary permits for Fekola Regional and Fekola underground). In addition, the Goose Project is expected to commence gold production in the first quarter of 2025 and contribute between 220,000 and 260,000 ounces of gold production in calendar year 2025. The Company still expects gold production from the Goose Project to be approximately 300,000 ounces per year over the first five years of operation. As a result of the expected completion of several capital projects in 2024 and early 2025, the Company also expects that there will be a significant decrease in both sustaining and growth capital expenditures in 2025.

Construction of the Goose Project is progressing on track, with the project remaining on schedule for first gold pour in the first quarter of 2025. Construction continues ahead of schedule within the mill and processing buildings, along with preparatory work for peak construction activities in the second and third quarters of 2024. Mine development is well underway at the Echo Pit and Umwelt Underground mine to generate high-grade stockpiles prior to mill commissioning. Following the successful completion of the 2023 sealift, construction of the WIR is being finalized and scheduled to be fully operational by February 23, 2024, transporting all required materials from the MLA to the Goose Project site by the end of April 2024.

Results of the Fekola Complex technical report outlining the trucking of ore from the Anaconda Area will be released in the first quarter of 2024. Results indicate that the trucking of both oxide and sulphide ore from Fekola Regional to be toll milled by the Fekola mill is the optimal option to maximize the value of Fekola Regional, and to extend the processing life of the Fekola mill.

The Company has completed a detailed review of the Gramalote Project, including the facility size and location, power supply, mining and processing options, tailings design, resettlement, potential construction sequencing, and camp design to identify potential cost savings to develop a smaller scale project. A formal study commenced in the fourth quarter of 2023, with the goal of completing a PEA by the end of the second quarter of 2024.

The Company's ongoing strategy is to continue to maximize profitable production from its mines, further advance its pipeline of remaining development and exploration projects, evaluate new exploration, development and production opportunities and continue to pay an industry leading dividend yield.

NON-IFRS MEASURES

Cash operating costs per gold ounce sold and total cash costs per gold ounce sold

''Cash operating costs per gold ounce'' and "total cash costs per gold ounce" are common financial performance measures in the gold mining industry but, as non-IFRS measures, they do not have a standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other issuers. Management believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate our performance and ability to generate cash flow. Accordingly, these measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The measures, along with sales, are considered to be a key indicator of the Company's ability to generate earnings and cash flow from its mining operations.

Cash cost figures are calculated on a sales basis in accordance with a standard developed by The Gold Institute, which was a worldwide association of suppliers of gold and gold products and included leading North American gold producers. The Gold Institute ceased operations in 2002, but the standard is the accepted standard of reporting cash cost of production in North America. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measures of other companies. Other companies may calculate these measures differently. Cash operating costs and total cash costs per gold ounce sold are derived from amounts included in the statement of operations and include mine site operating costs such as mining, processing, smelting, refining, transportation costs, royalties and production taxes, less silver by-product credits. The tables below show a reconciliation of cash operating costs per gold ounce sold and total cash costs per gold ounce sold to production costs as extracted from the annual consolidated financial statements on a consolidated and a mine-by-mine basis (dollars in thousands):

Cash operating costs per gold ounce produced

In addition to cash operating costs on a per gold ounce sold basis, the Company also presents cash operating costs on a per gold ounce produced basis. Cash operating costs per gold ounce produced is derived from amounts included in the statement of operations and include mine site operating costs such as mining, processing, smelting, refining, transportation costs, less silver by-product credits. The tables below show a reconciliation of cash operating costs per gold ounce produced to production costs as extracted from the annual consolidated financial statements on a consolidated and a mine-by-mine basis (dollars in thousands):

All-in sustaining costs per gold ounce

In June 2013, the World Gold Council, a non-regulatory association of the world's leading gold mining companies established to promote the use of gold to industry, consumers and investors, provided guidance for the calculation of the measure "all-in sustaining costs per gold ounce", but as a non-IFRS measure, it does not have a standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other issuers. The original World Gold Council standard became effective January 1, 2014 with further updates announced on November 16, 2018 which were effective starting January 1, 2019.

Management believes that the all-in sustaining costs per gold ounce measure provides additional insight into the costs of producing gold by capturing all of the expenditures required for the discovery, development and sustaining of gold production and allows the Company to assess its ability to support capital expenditures to sustain future production from the generation of operating cash flows. Management believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company's performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measures of other companies. The Company has applied the principles of the World Gold Council recommendations and has reported all-in sustaining costs on a sales basis. Other companies may calculate these measures differently.

B2Gold defines all-in sustaining costs per ounce as the sum of cash operating costs, royalties and production taxes, capital expenditures and exploration costs that are sustaining in nature, sustaining lease expenditures, corporate general and administrative costs, share-based payment expenses related to RSUs/DSUs/PSUs/RPUs, community relations expenditures, reclamation liability accretion and realized (gains) losses on fuel derivative contracts, all divided by the total gold ounces sold to arrive at a per ounce figure.

Adjusted net income and adjusted earnings per share - basic

Adjusted net income and adjusted earnings per share - basic are non-IFRS measures that do not have a standardized meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other issuers. The Company defines adjusted net income as net income attributable to shareholders of the Company adjusted for non-recurring items and also significant recurring non-cash items. The Company defines adjusted earnings per share - basic as adjusted net income divided by the basic weighted number of common shares outstanding.

Management believes that the presentation of adjusted net income and adjusted earnings per share - basic is appropriate to provide additional information to investors regarding items that we do not expect to continue at the same level in the future or that management does not believe to be a reflection of the Company's ongoing operating performance. Management further believes that its presentation of these non-IFRS financial measures provide information that is useful to investors because they are important indicators of the strength of our operations and the performance of our core business. Accordingly, it is intended to provide additional information and should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS. Other companies may calculate this measure differently.

A reconciliation of net (loss) income to adjusted net income as extracted from the annual consolidated financial statements is set out in the table below:
