Fortuna Drills 7.3 g/t Au Over 16.1 Meters At Sunbird At Séguéla Mine

Key Concepts

• Fortuna Mining: A mining company.
• Sunbird Location: A specific drilling site at the Sigua mine.
• Sigua Mine: A mine located in Kotivvoir.
• Gold Grade: Measured in grams per ton (g/t), indicating the concentration of gold in the ore.
• True Width: The actual thickness of a mineralized zone, as opposed to the drilled width.
• Down Plunge: Extending deeper into the earth along the direction of the ore body's dip.
• Mineralized Zone: An area containing economically significant amounts of minerals.
• Underground Shoot: A concentrated zone of high-grade mineralization within a larger ore body.
• Infill and Extension Program: Drilling activities aimed at increasing the confidence in existing resources and extending them.
• Resource Confidence: The level of certainty about the quantity and grade of mineral resources.

Fortuna Mining's Sunbird Drilling Update

This update focuses on the recent drilling results from Fortuna Mining's Sunbird location at the Sigua mine in Kotivvoir. The company has reported significant success in expanding the underground potential of the deposit.

Drilling Highlights and Intersections

• Significant Intersections:

  • 7.3 g/t gold over 16.1 meters.
  • 5.2 g/t gold over a true width of 6.3 meters.
  • 6 g/t gold over a true width of 11.9 meters.
  • 8.3 g/t gold over 11.9 meters.
  • 9 g/t gold over 5.6 meters.
  • 9.5 g/t gold over 5.6 meters.
  • 15.6 g/t gold over 5.6 meters.
  • 6 g/t gold over 9.8 meters.

• Expansion of Mineralized Zones:

  • The central mineralized zone has been extended a further 150 meters down plunge, where it remains open.
  • A lower shoot has been extended another 200 meters down plunge.

• Depth and Extent:

  • Mineralization has now been intersected extending more than 1.3 kilometers down plunge.
  • This extends to approximately 700 meters below the surface.

Drilling Program Details

• Program Scope: Fortuna Mining has completed 40 drill holes, totaling 15,088 meters, as part of an infill and extension program.
• Objective: The program aims to upgrade resource confidence.
• Ongoing Operations: Five drill rigs are currently active at the site.

Underground Study Initiation

• Fortuna Mining has initiated an underground study, indicating a progression towards potential underground development or further detailed evaluation of the deposit.

Commentary from Senior VP of Exploration

• Paul Weeden, Senior VP of Exploration at Fortuna, stated that drilling at Sunbird has been "very successful in expanding the underground potential."
• He highlighted that the deepest holes to date have intersected "multiple high-grade intervals."

Site Context and Future Plans

• A map was presented showing the Sunbird location relative to the mill and processing plant at Sigua.
• The presenter, Chris Marcus of Arcadia Economics, plans to visit the Sigua mine in November to gather further commentary from Paul Weeden and provide a tour of the site, referencing a previous video tour.

Conclusion

Fortuna Mining's drilling at the Sunbird location of the Sigua mine has yielded highly encouraging results, demonstrating significant expansion of high-grade gold mineralization both vertically and along plunge. The discovery of a second underground shoot and the extension of existing zones, coupled with the initiation of an underground study, suggest a robust and growing resource base. The ongoing drilling program, with multiple rigs active, is focused on increasing resource confidence and further defining the extent of the mineralization, which now reaches over 1.3 kilometers down plunge and approximately 700 meters below the surface.
