Cora Gold Limited ('Cora' or 'the Company')
73m @ 2.24 g/t Au at Zone B and 34m @ 3.06 g/t Au at Zone A, Sanankoro Gold Project
Cora Gold Limited, the West African focused gold company, is pleased to announce the twelfth 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 Company focussed the drill campaign on both resource growth as well as infill drilling to convert existing Inferred resources to Indicated. The drill results have continued to be extremely encouraging throughout the campaign with high-grade results in generally shallow oxide ore.
HIGHLIGHTS

· 22m @ 3.73 g/t Au from 117m in SC0556
· 2m @ 17.9 g/t Au from 39m in SC0553 and
· 23m @ 1.62 g/t Au from 60m in SC0553
Zone A
· 34m @ 3.06 g/t Au from 61m in hole SC0521
· 59m @ 1.28 g/t Au from 60m in hole SC0523
· 2m @ 34.85 g/t Au from 81m in hole SC0519
· 36m @ 1.65 g/t Au from 66m in hole SC0543
· 30m @ 1.85 g/t Au from 96m in hole SC0544
· Results show both good infill continuity and extensions along strike and at depth beyond existing pit shells
Bert Monro, CEO of Cora, commented, "To have two more holes of over 100 gramme metres, taking the total number of +100 gramme metre holes to 13 in this drill campaign, is extremely exciting and also very encouraging as we approach an updated mineral resource estimate ('MRE'). The results continue to show good consistency of widths and grades in oxide ore which offers us further encouragement as we look towards the DFS which is already underway.
"The RC drill campaign is now complete and we will expect the final assay results over the coming weeks in advance of an updated MRE. We look forward to updating shareholders in the near future with further news."

Relevance of the results
The intercepts reported confirm strong grade continuity within the 2019 pit shells and extension of these on strike and at depth. Management believes recent metallurgical coring has clearly evidenced the extreme depth of weathering and consequent strong oxide resource potential of both our Zone A and Zone B1 deposits.
The results reported for Zone A complete the resource drilling for this prospect and show resource and metallurgical drill hole assay results, which clearly consolidate a 50-70m wide, 60o east-dipping orebody which extends at least 200m down-dip from surface to well beyond the 2019 pit shell limits.
The drill results reported for Zone B1 present the first of the Phase 2 resource consolidation programme. The systematic infill pattern is confirming the continuity of the high-grade vein network along the eastern contact of the shear zone with new assays and visible gold ('VG') logging showing strong strike and dip correlation with previous high-grade intercepts such as 2m @ 146.4 g/t Au in hole SC0471 and 8m @ 19.11 g/t Au in hole SC459.
Current metallurgical and resource coring is pushing the depth of oxide in Zone B1 to greater than 150m vertical from surface. Bottle Roll recoveries are +90% to the extent of current drilling intercepts and core samples are currently being shipped to ALS Perth for metallurgical test work.
Plans of the drill intercepts and annotated drill sections Zone B1 1297525N and Zone A 1296000N and 1296100N are included to illustrate the grade and geological context of the reported results.
Details
The Company is pleased to report the assay results from the latest 55 holes in Cora's 2021 programme from Selin, Zone A and Zone B1, including various holes reported in ranges SC0518 to SC0556, SC1032 to SC1048 and SD0024 to SD0037. Phase 2 (P2) has focused resource consolidation on Selin, Zone A and Zone B1 pit shells, growing and closing gaps between existing pits.
Holes - Metres - Intercepts Reported - Metres Sent for Assay
The intercepts reported equate to the latest 6,697m of an expanded +40,000m resource programme and are hosted on thirty-nine 25m sections between 1295825N and 1305670N. As of 6 October 2021, 376 holes have been completed totalling 39,791m of reverse circulation ('RC') drilling and 3,406.6m of diamond drill ('DD') coring. The Company has received assay results for 26,752 sampled intervals which equates to 88% of the total 30,360 samples submitted to date. There are 3,608 samples still to be reported.
The results reported herein were generated from 7,402 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 A, Zone B and Zone C 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 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 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. There is no surface resource declared for Zone C currently but in response to the success of the P1 results, a detailed P2 programme has been devised to endeavour to create a new first oxide resource. The SWSZ is high in the priority list for drilling in the future 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 130m vertically within the central mineralised fault zone. Below the saprolite lies a 35-40m thick transition zone ending in top of fresh rock at between 160 to 170m.
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.

Notes
Cora is a gold company focused on two world class gold regions in Mali and Senegal in West Africa. Historical exploration has resulted in the highly prospective Sanankoro Gold Discovery, in addition to multiple, high potential, drill ready gold targets within its broader portfolio. Cora's primary focus is on further developing Sanankoro in the Yanfolila Gold Belt (Southern Mali), which Cora believes has the potential for a standalone mine development. Sanankoro has a positive Scoping Study published on it showing an 107% IRR and US$41.5m NPV8 at a US$1,500 gold price. Cora's highly experienced management team has a proven track record in making multi-million-ounce gold discoveries, which have been developed into operating mines.
