Fortuna Silver provides Sunbird exploration update

Published by , Editor
Global Mining Review,

Fortuna Silver Mines Inc. has provided an update on its Sunbird exploration programme at the Séguéla gold project, located in Côte d’Ivoire.

Paul Weedon, Senior Vice President of Exploration, commented: “Following the release of Sunbird´s maiden inferred mineral resource containing 350 000 gold (Au) oz in March 2022, expansion drilling has continued to grow the high grade mineralised footprint at depth and beyond the initial maiden resource envelope”

“Results such as 28.2 g/t Au over 3.5 m from drill hole SGRD1408 and 12.6 g/t Au over 7.7 m from drill hole SGRD1422 highlight the open nature of the deposit mineralisation,” added Weedon. “Further drilling is underway to test these extensions, with drill hole SGRD1423, a further 100 m down plunge, intersecting several points of visible gold.”

Weedon concluded: “In addition to the exploration success at Sunbird this field season, target generation elsewhere on the Séguéla property has continued to grow the portfolio with several new very encouraging prospects identified.”

Sunbird Prospect drill highlights include:

  • SGRD1405: 18.3 g/t Au over an estimated true width of 11.9 m from 168 m.
  • SGRD1408: 28.2 g/t Au over an estimated true width of 3.5 m from 351 m.
  • SGRD1421: 6.1 g/t Au over an estimated true width of 8.4 m from 252 m.
  • SGRD1422: 12.6 g/t Au over an estimated true width of 7.7 m from 319 m.

Subsequent to the release of Sunbird´s maiden inferred mineral resource of 3.4 million t at an average grade of 3.16 g/t Au containing 350 000 Au oz, expansion drilling further down-dip and down-plunge has continued to intersect high grade mineralisation beyond the initial optimised pit shell used to constrain the maiden inferred mineral resource.

Drilling has successfully intersected an interpreted continuation of the core high grade mineralisation a further 100 m down-plunge from previous intersections with drill hole SGRD1408 intersecting 28.2 g/t Au over an estimated true width of 3.5 m and drill hole SGRD1422 intersecting 12.6 g/t Au over an estimated true width of 7.7 m. Assays are pending for drill hole SGRD1423, which intersected several points of visible gold a further 100 m down plunge. This structure remains open at depth, some 350 m below surface.

In addition to extending mineralisation at depth, drilling was also designed to further define the central high-grade core, with a total of eight holes consistently intersecting high grades (greater than 100 g x m), including the most recent drill hole SGRD1405 intersecting 18.3 g/t Au over an estimated true width of 11.9 m from 168 m down-hole.

An additional 5110 m 15-hole programme to infill and extend the depth potential has commenced with four holes completed to date. Drill hole SGDD095, for which assays are pending, intersected more than five points of visible gold to 2 mm dia. in geological logging of the drill core. This interval has the potential to extend the high grade core a further 25 m to the north.
