的 Séguéla 黄金 Project in Côte d’Ivoire consists of the resource-defined, 近地表天线, Koula, 刺, 博尔德, and 旧 orogenic lode-style deposits. Within a total land package of 62,000公顷, there are an additional 22 highly prospective targets. It is located near existing infrastructure, including grid power, transport, and water resources. (纬度:8°8.905' N, Longitude: 6° 47.312' W)
In September 2021 Fortuna made the decision to proceed with the construction of an open pit gold mine at Séguéla. Long lead items have been procured and the development teams are commencing work on the ground. Séguéla will become our fifth mine with the first gold pour projected by mid 2023. 的 mine has compelling economics, with a nine year mine life in reserves. 的 initial six 年 are expected to report 130,000 ounces of gold production annually. With the total initial capital investment of $173.500万年, the anticipated construction schedule is approximately 20 months and ramp-up to name plate capacity of 3,750 tpd is expected in the third quarter of 2023.

GEOLOGY AND MINERALIZATION
的 Séguéla 黄金 Project is situated within the Paleoproterozoic (“Birimian”) Baoule-Mossi Domain of the West African Craton. Two cycles of volcanism/sedimentation are recognised within the Birimian rocks of the Baoule-Mossi Domain; each followed by a period of orogenesis, and together described as the Eburnian Orogeny which is dated c. 2.19–2.08 Ga. Rocks of the Baoule-Mossi Domain are primarily polyphase granitoids, and volcano-sedimentary sequences forming granite-greenstone terranes. 的 first cycle of sedimentation and orogenesis (“Eburnian 1”) is described by the accumulation of volcanic and volcaniclastic rocks; then subsequently intruded by early stage granitoids. Following a period of uplift and erosion, the Eburnian 2 cycle is described by the filling of intra-montaine basins with predominantly arenaceous sediments of the Tarkwaian Series.
- 的 天线存款 occurs within a greenstone package deposited during Eburnian 1, is an orogenic lode-style gold system, hosted by a brittle-ductile quartz-albite vein stockwork predominantly contained within flow banded rhyolite units.
- 的 Koula存款 is located approximately one kilometer to the east of 天线 and was discovered through field reconnaissance and coincident recent artisanal workings in an area previously considered to be a lower exploration priority. 结果 from the first of four drill holes testing the projected depth extensions approximately 120 meters down-plunge from the previously deepest intersection of 14 meters at 4.3 g / t盟 included an intersection of six meters at 10.8 g / t盟 from 355 meters downhole.
- 的 旧的存款 is associated with an interpreted D2 sinistral shear zone. Significant mineralization is restricted to the more reactive and competent tholeiitic basalt unit and is best developed in zones of strong brittle-ductile brecciation and shearing, with selective sericite+/-silica alteration and intense quartz and quartz-carbonate veining.
- 的 博尔德 and 刺 prospects are both located within a distinct northerly-trending litho-structural corridor that extends from 博尔德 in the south to Gabbro in the north. 黄金 mineralization at the 博尔德 and 刺 prospects is associated with strongly foliated or mylonitized, quartz/quartz-carbonate veined basalt and the margins of the felsic intrusives.

- 笔记
- Mineral Reserves and Mineral Resources are as defined by the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves
- Mineral Resources are exclusive of Mineral Reserves
- Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability
- Factors that could materially affect the reported Mineral Resources or Mineral Reserves include; changes in metal price and exchange rate assumptions; changes in local interpretations of mineralization; changes to assumed metallurgical recoveries, mining dilution and recovery; and assumptions as to the continued ability to access the site, retain mineral and surface rights titles, maintain environmental and other regulatory permits, and maintain the social license to operate
- Mineral Resources and Reserves for the Séguéla gold Project are estimated and reported as of March 31, 2021 with the exception of the 太阳鸟 deposit which is estimated and reported as of December 31, 2021
- Mineral Reserves for Séguéla are reported constrained within optimized pit shells at an incremental cut-off grade of 0.54 g / t盟 for 天线, 0.55 g / t盟 for 刺, 0.55 g / t盟 for 博尔德, 0.56 g / t盟 for Koula and 0.56 g / t盟 for 旧的存款s based on an assumed gold price of US$1,500/oz, metallurgical recovery rate of 94.5%, mining cost of US$2.87/t for 天线, US$2.74/t for 刺, US$2.81/t for 博尔德, US$2.85/t for Koula and US$2.93/t for 旧, processing and G&A费用为21美元.64/t, mining owner cost of US$1.30/t, refining cost of US$2.60/oz and royalty rate of 6%. 的 Mineral Reserves pit design were completed based on overall slope angle recommendations of between 37° and 57° for 天线, Koula and 刺 deposits from oxide to fresh weathering profiles, between 34° and 56° for 旧的存款 from oxide to fresh weathering profiles and 37° and 60° for 博尔德 deposit from oxide to fresh weathering profiles. 的 Mineral Reserves are reported in situ with modifying factors of 15% mining dilution and 90% mining recovery applied. Mineral Resources for Séguéla are reported in situ at a cut-off grade of 0.3 g / t盟 for 天线 and 0.5 g / t盟 for the satellite deposits, based on an assumed gold price of US$1,700/oz and constrained within preliminary pit shells. 的 Séguéla gold Project is subject to a 10% carried interest held by the government of Côte d'Ivoire.
