Lindero Mine, Argentina
As of December 31, 2022, the Lindero Mine has Proven and Probable Mineral Reserves of 79.2 Mt containing 1.4 Moz Au, in addition to Measured and Indicated Resources, exclusive of Mineral Reserves, of 29.5 Mt containing 399 koz Au, and Inferred Resources of 24.2 Mt containing 365 koz Au.
Since December 31, 2021, Mineral Reserve tonnes decreased by 11 percent, while gold grade remained unchanged at 0.57 g/t Au. Changes are primarily due to mining related depletion and sterilization of 6.0 Mt of material containing 158 koz Au delivered to the heap leach pad in 2022 and an increase in the reporting cut-off grade due to higher operating costs resulting in a decrease of 3.4 Mt containing 30 koz Au.
Measured and Indicated Resource gold ounces, exclusive of Mineral Reserves, decreased slightly by 16 koz Au or 4 percent since December 31, 2021 to 400 koz Au year-over-year, due to an increase in the cut-off grade used for reporting resources as a result of increased operating costs.
Inferred Resources tonnes decreased by 2.9 Mt or 11 percent, to 24.2 Mt since December 31, 2021 with the gold grade increasing 9 percent to 0.47 g/t. The decrease in Inferred Resources is due to the aforementioned changes in cut-off grade used for reporting resources.
Yaramoko Mine, Burkina Faso
As of December 31, 2022, the Yaramoko Mine has Proven and Probable Mineral Reserves of 1.2 Mt containing 220 koz Au, in addition to Measured and Indicated Resources, exclusive of Mineral Reserves, of 0.5 Mt containing 89 koz Au, and Inferred Resources of 0.14 Mt containing 25 koz Au.
There has been no material change to the previously reported Mineral Reserves and Mineral Resources as of June 30, 2022 (refer to Fortuna news release dated January 27, 2023) other than production related depletion to December 31, 2022.
San Jose Mine, Mexico
As of December 31, 2022, the San Jose Mine has Proven and Probable Mineral Reserves of 2.1 Mt containing 11.8 Moz Ag and 80 koz Au, in addition to Inferred Resources of 2.5 Mt containing a further 9.6 Moz Ag and 67 koz Au.
Year-over-year, Mineral Reserves decreased 28 percent in terms of tonnes, while silver grade decreased 4 percent and gold grade decreased 1 percent after net changes of minus 950,000 tonnes resulting from production-related depletion, application of higher cut-off grades related to increases in operational costs amounting to a decrease of 267,000 tonnes and the upgrading and conversion of 370,000 tonnes of Inferred Resources to Mineral Reserves due to infill and exploration drilling. Silver and gold grades decreased slightly to 172 g/t and 1.16 g/t, respectively due to upgraded grades having lower average grades than those depleted in 2022.
Measured and Indicated Resource tonnes exclusive of Mineral Reserves remained relatively unchanged year-over-year with tonnes decreasing by 3 percent and silver and gold grades increasing by 10 percent due to an increase in the cut-off grade used for reporting resources because of increased operating costs.
Year-over-year, Inferred Resources decreased 16 percent in terms of tonnes, with grades decreasing for silver and gold by 6 percent and 11 percent, respectively. The net variation is due primarily to reductions resulting from the upgrading of Inferred Resources related to infill drilling and an increase of 106,000 tonnes due to exploration drilling activities.
The Brownfields exploration program budget for 2023 at the San Jose Mine is US$3.3 million, which includes 5,500 meters of diamond drilling, focused on extensions to the Magdalena, Trinidad and Victoria systems, as well as work along the Taviche corridor (refer to Fortuna news release dated January 17, 2023).
Caylloma Mine, Peru
As of December 31, 2022, the Caylloma Mine has Proven and Probable Mineral Reserves of 3.2 Mt containing 8.3 Moz Ag, 15 koz Au, 85 kt Pb, and 124 kt Zn in addition to Inferred Resources of 5.0 Mt containing 16.9 Moz Ag, 72 koz Au, 112 kt Pb, and 171 kt Zn.
Year-over-year, Mineral Reserve tonnes increased by 1 percent, while silver grade decreased 4 percent to 81 g/t, lead grade increased 5 percent to 2.66 %, and zinc grade increased 5 percent to 3.88 %. Changes are primarily due to mining related depletion of 497,000 tonnes, upgrading and conversion of 548,000 tonnes of Inferred Resources to Mineral Reserves and the addition of 594,000 tonnes due to successful infill drill and exploration programs, respectively, focused on the Animas, Animas NE, Nancy and associated splay veins counteracted by a decrease by 336,000 tonnes due to higher cut-off values related to increases in operational costs and an additional decrease of 279,000 tonnes as a result of changes in estimation parameters, geological interpretation and commercial terms.
Measured and Indicated Resource tonnes, exclusive of Mineral Reserves, increased slightly by 4 percent year-over-year to 2.8 Mt with silver, lead and zinc grades decreasing slightly by 7 percent, 1 percent and 2 percent, respectively due to the same reasons as detailed for reserves.
Inferred Resources tonnes increased by 31 percent year-over-year. Silver and zinc grades decreased 9 percent and 2 percent, respectively whereas lead grades increased by 10 percent. The increase in Inferred Mineral Resources is primarily due to the inclusion of 1.9 Mt of new resources in relation to exploration drilling expanding identified mineralized material in the lower levels of the Animas and Animas NE veins counteracted by the infill drill program of the Animas and Animas NE veins resulting in the upgrading of Inferred Mineral Resources to Mineral Reserves.
Management is in the process of conducting a cost-benefit analysis to assess increasing plant throughput. This is supported by the expanded mineralization which remains open at depth in the Animas and Animas NE veins.
Séguéla gold Project, Côte d'Ivoire
As of December 31, 2022, the Séguéla gold Project has Proven and Probable Mineral Reserves of 12.1 Mt containing 1.1 Moz Au, in addition to Indicated Resources of 7.1 Mt containing 523 koz Au and Inferred Resources of 5.7 Mt containing 610 koz Au. There has been no material change to the previously reported Mineral Reserves and Mineral Resources (refer to Fortuna news release dated December 5, 2022).
Infill drilling at the Sunbird Deposit is currently in progress with a 2023 program budget of US$1.7 million, which includes 9,500 meters of diamond drilling, aimed at upgrading Inferred to Indicated Resources with the ultimate intention of conversion to Mineral Reserves once sufficient studies are complete to determine modifying factors.
Arizaro Project, Lindero Property, Argentina
The Lindero Property contains two known porphyry gold-copper deposits. The Lindero Deposit, the focus of current mining activities as described above in the Lindero Mine section and the Arizaro Deposit which is located 3.2 km southeast of the Lindero Deposit.
Gold-copper mineralization at Arizaro is associated with two different mineralizing events. The strongest is a non-outcropping intrusive which occurs in the north part of the porphyry with an elongated shape trending northeast to southwest for more than 400 meters with an estimated average width of 60 meters. The other mineralizing event is in the center of the system and is related to breccias and micro-breccias which have a semi-oval shape at surface. In the center, there is a higher-grade core with a semi-ellipsoidal form, extending north-south for 480 meters with an estimated average width of 50 meters. The Arizaro Deposit has mineralization styles with copper-gold grades that are strongly correlated with different alteration assemblages. Mineralization is mainly associated with potassic alteration. This occurs generally in multi-directional veins, vein stockworks and disseminations. In some areas, the vein density is high, forming vein stockworks in the intrusive rocks. These vein stockworks are limited to magnetite-biotite veinlets, quartz-magnetite-chalcopyrite veinlets, late magnetite breccias and in late-stage mineralization events, anhydrite-sulfide veinlets. Chalcopyrite and bornite are the main copper minerals. Gold is mainly associated with chalcopyrite, quartz, and anhydrite veinlets.
A total of 65 surface diamond drill holes totaling 16,166 meters were used in the modelling of the Inferred Mineral Resource at Arizaro in conjunction with surface mapping to construct three-dimensional wireframes to define individual lithologic structures. Drill hole samples were selected inside these wireframes, coded, composited and grade top cuts applied if applicable. Boundaries were treated as hard with statistical and geostatistical analysis conducted on composites identified in individual lithologic units. Gold and copper grades were estimated into a geological block model consisting of 10m x 10m x 8m selective mining units. Grades were estimated by ordinary kriging and constrained within an ultimate pit shell based on estimated metal prices and actual costs experienced at the Lindero Mine, along with estimated geotechnical constraints and metallurgical recoveries to fulfill the reasonable prospects for eventual economic extraction. Estimated grades were validated globally, locally, and visually prior to tabulation of the Mineral Resources.
As of December 31, 2022, the Arizaro Project has Inferred Mineral Resources of 22.1 Mt averaging 0.39 g/t Au containing 280 koz Au. Mineralization remains open at depth and along the trend of the northeast to southwest striking porphyry.
