Cora Gold Limited (CORA.L) Final drill results from Zone B deposit, Sanankoro

17m @ 17.13 g/t Au and 19m @ 6.14 g/t Au in the final drill results from Zone B deposit, Sanankoro

Cora Gold Limited, the West African focused gold company, is pleased to announce the fourteenth, and final, set of drill results from its largest ever +40,000m drill campaign at its Sanankoro Gold Project (‘Sanankoro’ or ‘the Project’) in Southern Mali. The drill results have continued to be extremely encouraging throughout the campaign with high-grade results in generally shallow oxide ore. An updated mineral resource estimate (‘MRE’) is expected in the coming weeks.


· 17m @ 17.13g/t Au from 89m in hole SC0561

· 19m @ 6.14 g/t Au from 59m in hole SC0565

· 22m @ 3.28 g/t Au from 88m in hole SC0559

· 28m @ 2.26 g/t Au from 71m in hole SC0560

· 73m @ 0.71 g/t Au from 95m in hole SC0557

· 54m @ 0.83 g/t Au from 120m in hole SC0558

· 32m @ 1.36 g/t Au from 16m in hole SC0563

· Oxide mineralisation has been defined continuously to +190m vertically in recent metallurgical core drilling and density determinations

· Zone B1 resource remains open in all directions

Bert Monro, CEO of Cora, commented, “This drill campaign has delivered consistently positive results and this last set of samples means that we finish on a high note, reporting some of our best drill hole results to date. 17m @ 17.13 g/t Au and 19m @ 6.14 g/t Au are not only two further excellent drill holes in isolation, but in the context of our full campaign we have had 15 holes of +100 gramme metre which is a fantastic achievement for the exploration team on the ground. Additionally, the additional depth of oxidisation, to greater than 190m, has potentially positive implications as we look towards mining in the future. There has been a lot of hard work gone into this drill campaign from our team and contractors and I would like to thank them publicly for all their hard work.

“The next steps for the Company is the delivery of an updated MRE over the coming weeks. There have also been a number of DFS site visits over the last month with numerous concurrent work streams ongoing and I look forward to sharing more on our DFS and development plans in due course.”

Relevance of the results

The intercepts reported complete the 2021 resource definition drilling for the Zone B1 deposit. Management believes the results reinforce the multiplicity of high-grade vein structures which occur across the Zone B1 resource, highlighted in this release as 17m @ 17.13 g/t Au from 89m in SC0561 and 19m @ 6.14 g/t Au from 59m in hole SC0565 and the previously reported 2m @ 146.43 g/t Au from 160m in SC0471 And 8m @ 19.11 g/t Au from 90m in SC0459. The high-grade veins anastomose across a 75m wide zone of lower grade oxide mineralisation which extends to depths in excess of 150m.

Recent resource and metallurgical coring has confirmed that Zone B1 has extremely deep weathering with shallow oxide densities measured to depths of 190m vertically, down-dip within the ore zone oxidation trough. Drill core samples have been composited and shipped to ALS Perth for metallurgical test work.

Plans of the drill intercepts and annotated drill cross sections Zone B1 1297525N to 1297625N are included to illustrate the grade and geological context of the reported results.

Holes – Metres – Intercepts Reported – Metres Sent for Assay

The intercepts reported equate to the latest 1,749m of an expanded +40,000m drill programme and are hosted on eight 50m cross sections between 1297550N and 1297725N. As of 21 October 2021, 379 holes have been completed totalling 39,791m of reverse circulation (‘RC’) drilling and 3,810m of diamond drill (‘DD’) coring. The Company has now reported all assay results for the total 30,360 RC resource samples submitted during the 2021 programme.

The results reported herein were generated from the last 1,082 submitted samples, which included a high level of 20% blind, independent, accredited QAQC samples. The intercepts reported have passed rigorous QAQC.

Background on the Zone B Geology

Sanankoro is located on the leading western edge of the Yanfolila-Kalana Volcanic Belt, which is the western-most expression of the cratonic Baoulé-Mossi domain, on the major transcrustal margin with the Siguiri Basin. There is major deep-seated structural architecture across the district which links the major gold mines at Siguiri, Lero, Tri-K, Kalana and Yanfolila.

On a project scale, Sanankoro is characterised by the 2km wide Sanankoro Shear Zone, which can be traced over 30km from Kabaya South in the western Yanfolila Mine to north of the Niger River beyond Selin and onto Karan. Within the project area, each of the prospects are underpinned by a strong linear parallel, and where strong mineralisation is developed, a pronounced localised NE-SW focused zone of en-echelon veining and associated sulphide development.

Zone A is the second major resource deposit at Sanankoro behind Selin and shores up the southern limit of the 11.5km long mineralised corridor, which forms the backbone to the Sanankoro Project. Zone A is the southern-most expression of the 010o trending central axis of the Sanankoro Shear Zone, which sits 900m west of the Selin Boundary Shear and hosts the 5.8km chain of open pit resources from Zone A through Zone B1, B2, B3 to Target 3. The deposits of this central trend verge westward mimicking the regional sense of thrusting.

Zone B is the third major resource deposit at Sanankoro behind Selin and A. It is the strike extension of Zone A, sitting 800m to the north. The Sanankoro Main Trend runs for 6km from south end of Zone A to the north end of Target 3. Detailed sectional drilling is required along the length of this major generative gold system. The local structural facing and stratigraphy of Zone B is very similar to Zone A with the western footwall sequences hosting more crystalline volcanic tuffaceous units and the eastern, hanging wall assemblages being more basinal sediments. Zone B hosts an impressive scale of hydrothermal activity and the broad horizontal widths of mineralisation observed in the recent drilling bodes well for future discovery potential along the central and southern sections of the Sanankoro Main Shear Zone (SMSZ).

Zone C sits 650 metres southwest of Zone A on the parallel, +7km long Sanankoro West Shear Zone (SWSZ) which can be traced along a chain of surface workings to the Excavator Prospect, 1.5km NNW of Target 3. The SWSZ is high in the priority list for drilling in a future programme and a number of SWSZ targets, beyond Zone C, will be tested for surface resource potential.

Zones A, B and C deposits are identical in style and typical of Siguiri Basin Deposits, fold-thrust controlled within pelitic and psammitic sediments and very deeply weathered (>120m from surface). There is a highly evolved weathering profile with a pronounced 8-10m thick duricrust-laterite ferro-cap, grading downward into a well-developed mottled zone until 20-25m and remains highly weathered until beyond 140m vertically within the central mineralised fault zone. Zone B1 has extremely deep weathering with shallow oxide densities measured to depths of 190m down-dip within the ore zone trough.

All of the host oxide lithologies are weathered to kaolin with only highly corroded quartz vein material remaining in-situ to mark the main gold faults. Diamond core shows the host lithologies to be predominantly variably grained basinal pelites and sandstones with minor horizons of small quartz clast, matrix-supported greywacke inter-bedded within the sequence. A minor intercept of diorite has been identified but does not form an important control to the mineralisation currently drill tested at Zone A or C. The primary sulphide is pyrite disseminated around central vein networks and enveloped by a broader hydrothermal halo of silica flooding, sericite and ankerite.
