Cora Gold reports further positive Sanankoro drill results

Cora Gold Limited (LON:CORA), the West African focused gold company, has providedfurther drill results from the ongoing 2026 mineral resource estimate growth drilling programme being conducted at the Company’s Sanankoro Gold Project in southern Mali. The drill programme aims to unlock the broader long-term potential of the Project through an extensive resource growth and exploration programme, targeting both extensions to existing deposits and a number of highly prospective near-mine greenfield targets.

The latest assay results have been received from drilling at the Selin deposit, the largest and most continuous of the MRE deposits at Sanankoro, with a continuous strike extent of >2.75km.  Due to its size and the current depth of drilling, selected locations of the deposit were targeted by this 2026 MRE drill programme, with 21 reverse circulation (‘RC’) holes drilled for 3,748m. All holes were designed to test for extensions to mineralisation outside of the MRE, mainly targeting new Inferred mineralisation under the main zone and along strike continuity of the ‘blind’ western zone, which is relatively untested.  The targeted drill programme at Selin completed its objective, defining new extensions to the mineralisation outside of the MRE and demonstrating grade continuity. Further drilling is required in the future as mineralisation remains open at depth beyond the current limits of the MRE model.

Selin Drilling Highlights

●       Best intercepts from Selin include:

o        17m @ 1.65 g/t gold (‘Au’) from 113m in hole SC0725 “western zone”

o        23m @ 1.34 g/t Au from 38m in hole SC0726 “main zone”

o        18m @ 1.03 g/t Au from 111m in hole SC0728 “western zone”

o        14m @ 1.33 g/t Au from 146m in hole SC0729 “main zone”

o        12m @ 1.34 g/t Au from 185m in hole SC0729 “main zone”

o        16m @ 1.32 g/t Au from 177m in hole SC0730 “main zone”

o        13m @ 1.25 g/t Au from 169m in hole SC0743 “main zone”

o        15m @ 1.76 g/t Au from 143m in hole SC0744 “main zone”

o        22m @ 1.28 g/t Au from 135m in hole SC0745 “main zone”

●       The assay results continue to show the continuous nature of mineralisation and gold grade.

●       New intervals of mineralisation were intersected along the interpreted extensions of the ‘blind’ western zone, providing a key resource growth target in the future.

●       Results build on the recent high-grade gold intercepts from Zone B (see announcement dated 7 September 2026), giving further confidence in the potential to materially expand the Project’s current MRE inventory of 1.044 Moz and life of mine of 10.2 years.

●       The drill programme was 89% complete at the end of September and remains ongoing, with the diamond drill rig now onsite to complete deeper holes at Zone B.

●       Assays remain pending from Zone A, Zone C, Dakounkoura (‘Dako’), TRA07, Kary (Zone B south/west) and the remaining drill holes at Zone B.

Bert Monro, Chief Executive Officer of Cora, commented,

“Good mining operations are built around grade consistency and Selin continues to deliver as a robust gold deposit that will underpin the early years of our mine plan.

“It’s exciting to see the targeted drill programme intersect extensions to the relatively untested western zone. This is significant because any new resources defined at this zone will also help deepen the resources in the main zone by decreasing the strip ratio.

“These results build on the encouraging initial assays from Zone B. With assays pending from six drill areas and diamond drilling just starting, we believe that we are only just beginning to tap into the immense exploration potential at Sanankoro.”

Selin Drill Programme Overview

The 2026 MRE growth drill programme at Selin comprised of 21 RC holes (3,748m) and was primarily located around the central and southern areas of the deposit, near where the north and south reserve pits join and where there is a flex in the structural trend controlling the mineralisation as shown on the map below (Figure 2). The drilling also targeted what is referred to as the ‘blind’ western zone, which is weakly mineralised near surface and stronger at depth.  Mineralisation from this zone that has been defined and modelled previously is contained within the 2025 MRE Reasonable Prospects for Eventual Economic Extraction (‘RPEEE’) pit shell based on a gold price of US$2,400/oz.

Selin Drilling Results Summary

Below, in Table 1, is the full summary of the drill intervals for Selin, where the reporting criteria cut-off is Au≥0.1 g/t Au, minimum 3m interval and ≥6m waste included (where all drill holes dip is -60 degrees and drill hole azimuth 270 degrees). 

Table 1. Summary of the drill intervals from Selin

Three holes (SC0722, SC0746 and SC0749) did not intersect mineralisation.

Selected drill sections from the drill programme

In Figure 3 below, drill hole SC0725, targeting the ‘blind’ western zone, intersected 17m @ 1.65 g/t Au, from 144m, and also intersected a second deeper zone, 9m @ 0.93 g/t Au from 144m. Both intervals are within the previous 2025 MRE RPEEE pit shell, but importantly outside of the MRE mineralised grade shell. New mineralisation intersected within the previous RPEEE pit shell is free carry and once re-modelled, is expected to add new resources to the next MRE update.

Figure 4, below, shows the reported drill intercepts for hole SC0729, which targeted deeper extensions to the main zone mineralisation below and outside the previous 2025 MRE. The section also shows that the reserve pit and MRE RPEEE pit shell ‘bottom out’ at or near the base of the MRE model at a relatively shallow depth of 75m and 100m respectively beneath the surface topography.

Hole SC0729 recorded two intercepts, 14m @ 1.33 g/t Au from 146m, and 12m @ 1.34 g/t Au from 185m, with both mineralisation zones remaining open at depth for future MRE growth.

Figure 5, below, shows SC0729 and its surrounding 2026 drill holes, which all intersected mineralisation beneath the base of the 2025 MRE model. Collectively, once re-modelled, this new mineralisation is expected to allow the updated MRE RPEEE pit optimisation to go deeper and add more resources in this central area where both the north and south reserve pits join.

Hole SC0747 in Figure 6 below, targeted shallow extensions to the main zone underneath the shallow reserve pit design and 2025 MRE RPEEE pit shell at the southern end of the Selin deposit.  The hole recorded an intercept of 23m @ 0.85 g/t Au from 109m, proving up the continuity of the mineralisation, and is expected to now allow for the MRE to be modelled and extended to the same depth as to the north and south of the hole.
