This 2021/2022 phase of drilling is composed of 6,993 m of RC and 897 m of aircore (AC) drilling.

RC was ubiquitously sampled on 1 m intervals. Each rod string is 6 m in length and is checked and marked with grease every 1 m to allow personnel to observe sampling and drill progress. The driller will sound a horn at the end of each 1 m interval, warning the samplers to switch bags at the cyclone.

All industry standard RC sample quality procedures were applied, and each shift a geologist was present to ensure sample quality was maintained, holes were not stopped in mineralisation and activity reporting monitored cost control. No detailed logging or sampling was conducted at the rigs.

All bulk 1 m samples were transported immediately upon hole completion to a central bag farm next to the Sanankoro camp. No samples were left in the field. All samples drilled were shipped to the bag farm for splitting and logging under controlled and secured conditions.

The 1 m bulk samples are riffle split down to 5-6 kg using a three-tier 75:25 riffle splitter and a duplicate pair of 2-3 kg samples are then generated using a two-tier 50:50 riffle splitter. One sample is sent to the lab and the duplicate is stored for any future re-assay or reference.

All RC holes are photographed on chip tables and chip trayed after sampling and logging.

All RC holes are geologically logged and panned for visible gold on
1 m intervals concurrently with sampling.

The logging and panning results dictate whether the logging or senior geologist will instruct compositing in less favourable intersections of a hole. Composites of 4 m are possible in barren intersections.

The RC samples were sent to an accredited laboratory where they were pulverised to 85% passing 75 micron in a Labtechnics LM2 puck pulveriser and sub-sampled to provide 2 kg for CN bottle roll and/or a 50 g aliquot for fire assay. Bottle roll is the preferred assaying method for oxide materials and fire assay for fresh or sulphide-rich material.

AC was sampled and analysed as per the RC procedure.

RC was drilled using a 5^3/8" face-sampling hammer.

All drilling details and dates are recorded on hole logs and are stored in the COLLAR file in DATASHED™.

RC was drilled using a 5^3/8" face-sampling hammer leading a 4^1/2" standard rod string. Auxiliary booster-compressor air packs were used on deeper holes, normally >110 m, to ensure dry sample quality and recovery.

The RC drilling was sampled on a standard 1 m interval and recoveries assessed quantitively by weighing each sampled metre. A total of 6,698 RC samples and 844 AC weights were recorded during this drilling campaign in 2021/2022.

The practice of weighing drill chip samples immediately from recovery at the rig is Cora Gold Limited (Cora Gold) standard practice for all AC and RC drilling.

Sample quality and recovery are monitored at the rig during drilling shift both observationally by the geologist checking the moisture content, possible contamination and relative recovery along the bag line and quantitively by weighing each of the bulk 1 m samples direct from the cyclone before layout.

RC recoveries are logged and recorded in the database. Overall recoveries are >70% for the RC; there are no significant sample recovery issues. A geologist is always present at the rig to monitor and record sample quality.

All RC holes are logged, panned and sampled on a standard 1 m resolution. Every 1 m drilled is logged and panned before being sampled.

4 m compositing may be instructed in barren sections of drilled hole based on the results of the detailed logging.

All RC holes are photographed on chip tables and chip trayed after sampling and logging.

All AC and RC chip samples were weighed and riffle split to 2-3 kg for submission to the lab. All AC and RC holes are sampled in bulk, logged and panned on a standard 1 m interval. Compositing to 4 m may occur in barren geology.

A standard 5:25 sample QAQC was used throughout the 2021/2022 programme, composed of one standard, one blank, two duplicates, and one triplicate. Assay batches had a routine 20% QAQC component.

The database manager monitors all sampling and QAQC vetting of the assay batches.

Field duplicates assist in determining the representivity of subsamples.

QC category ratios

Subsamples are deemed appropriate for the reporting of Exploration Results.

Sample preparation involved oven drying, jaw crushing core P70 passing 2 mm, followed by total pulverisation through an LM2 puck pulveriser to a nominal 85% passing 75 microns.

Historically it has been proven that the nuggety, highly weathered nature of the Sanankoro oxide mineralisation is best head assayed by 2 kg bottle roll/atomic absorption spectrometry (AAS) with a 50 g fire assay/AAS on the bottle roll tail residue on all samples with Au values greater than 0.1 g/t Au. The bulk of the assay database is completed by this method.

A total of 29,899 bottle roll (Leachwell) assays were reported with 7,561 fire assay/AAS tails.

A standard 5:25 sample QAQC was used throughout the programme, composed of one standard, one blank, two duplicates, and one triplicate. The assay batches had a routine 20% QAQC component.

Standard type ratios

Certified reference material (CRM) standards were sourced from accredited suppliers Rocklabs.

Following review of the QAQC, the data are deemed appropriate for the reporting of Exploration Results.

The Competent Person has visually verified some significant RC intersections during the site visit related to the Mineral Resource in 2021.

Geology and sampling data were logged into Microsoft Excel format templates and sent via email to the database manager. Files were imported into Datashed via configured importers and passed through stringent validation. 

Validation included:

·   Logging codes checked against approved code lists

·   Interval overlaps and gaps

·   Records beyond end-of-hole.

All digital files received were archived on the workstation hosting the database. This was located on site with the database manager. Scheduled daily backups of the database and file archive were made to a NAS solution located at the same site. Nightly scheduled offsite backups were conducted to a verified backup service provider. All offsite backups are encrypted.

Overall, the drilling, logging, sampling, assaying and QAQC procedures are considered to be consistent with industry standard practice.

No adjustments or calibrations were made to any assay data used in this estimate.

Grid System: WGS84 UTM zone 29N (EPSG: 32629)

All surface survey features were surveyed with a LEICA GS18-T RTK differential global positioning system (GPS) to within a proven accuracy of 30 cm; Cora conducted the differential GPS work.

A large number of well distributed ground control points and features were used for the TERRABOTICS satellite survey. All points were set-out or picked-up using CG-LEICA.

TERRABOTICS UK produced a site specific 139 km² digital terrain model (DTM) with 0.3 m RL accuracy using tasked MAXAR orthorectified WV3 imagery flown in November-December 2020. The DTM was provided in February 2021 and utilised throughout the latest drill program from March to August 2021.

The TERRABOTICS DTM proved accurate from ongoing survey work to be within 30-50 cm RL. Differential GPS easting and northing showed better resolution.

The TERRABOTICS DTM is an acceptable topographic model for Sanankoro which defines the surface relief and maps the artisanal pits across the 139 km² area of interest accurately. The WV3 imagery maps the full cadastral and natural features across the project area.

The 2022 drilling utilised a WELLFORCE CHAMP north-seeking gyro throughout and every drilled RC hole has a detailed gyro DTH survey file. Historically, DTH surveys were conducted, used a REFLEX EZ-TRAC.

The nominal drillhole collar spacing is 50 m x 25 m and 50 m x 50 m.

Due to the orientation of drill traces on section, data between drillholes can be spaced as close as 10 m in places.

At this stage, no assessment of geological and grade continuity has been conducted.

The bulk of the drilling is orientated 090° or 270° orthogonal to the strike of the mineralised domains. Structural logging based on oriented core indicates that the main mineralisation controls are ±20° from 000 north and largely perpendicular to drill direction.

No orientation-based sampling bias has been identified in the dataset.

The full chain of custody is managed by Cora. Samples collected daily from the rigs and transported to the central bag farm and sample processing area next to the main Sanankoro camp where the bulk samples are logged, split and prepared for onward transport to the various labs.

The samples are stored on site and a truck collects available samples weekly and transports them to Cora Gold office in Bamako for registration and verification prior to onward delivery to ALS Ouagadougou.

The labs sign sample submissions as evidence of receipt.

Completed assay files and pdf certificates were distributed to the approved recipients by Lab LIMS. Assay files were imported as received to Datashed and then archived on the workstation hosting the database.

Database management software used is DATASHED version 4.6.4.2 with DB version 4.6.5 with MSSQL Server SQL2017 backend.

The Sanankoro Gold Project (area 341.87 km²) is located in the Yanfolila Gold Belt of southern Mali. The Sanankoro Gold Project comprises five contiguous gold exploration permits, being Bokoro II (area 63.1 km²; expiry date 25 August 2023), Bokoro-Est (area 100 km²; expiry date 18 September 2028), Dako II (area 44.66 km²; expiry date 31 December 2027), Kodiou (area 50 km²; expiry date 15 May 2023), and Sanankoro II (see below). The Definitive Feasibility Study is focused on Mineral Resources within the Sanankoro II gold exploration permit.

In accordance with the 2019 Mining Code of the Republic of Mali, the 84.11 km² Sanankoro II gold exploration permit was awarded to Cora Resources Mali SARL on 2 March 2021 (Arrêté no. 2021-0590-MMEE/SG). Cora Resources Mali SARL is registered in the Republic of Mali. The duration of the permit is three years, renewable twice at the holder's request, the duration of each renewal period is extended to three years - as such, the full-term expiry date of the Sanankoro gold exploration permit is 2 March 2030.

Cora Resources Mali SARL is a wholly owned subsidiary of Sankarani Ressources SARL which in turn is a 95% subsidiary of Cora Gold Limited. Sankarani Ressources SARL is registered in the Republic of Mali. Cora Gold Limited is registered in the British Virgin Islands. The residual 5% interest in Sankarani Ressources SARL may be acquired from a third party for the sum of US$1 million. In addition, the Sanankoro II permit is subject to a third party 1% net smelter return (NSR) royalty. All fees due to the government in respect of the Sanankoro II gold exploration permit have been paid and the permit is in good standing.

A gold exploration permit over the same area as that covered by the Sanankoro II gold exploration permit was previously held by Sankarani Ressources SARL. This permit expired on 1 February 2020, having been initially awarded on 1 February 2013.

Exploration activities on the original Sanankoro permit by previous workers have included geological mapping, rock chip sampling, termite sampling, trench sampling geophysical surveys and surface drilling - auger, RAB, AC, RC, and DC.

There were two previous companies who conducted work at Sanankoro, i.e. Randgold Resources Ltd (Randgold) between 2004 and 2008 and Gold Fields between 2008 and 2012.

During 2004 to 2008, Randgold conducted successive programs of soils and termites geochemical sampling on iterative 500 m, 200 m and 100 m grids. Broad blocks of gradient array induced polarisation (IP) were completed to assist drill targeting on the broad regional-scale surface anomalies. They drilled broad spaced 400 m x 100 m auger and RAB fences in search for bedrock targets.

During 2008 to 2012, Gold Fields conducted infill soils and termite sampling down to 100 m x 25 m resolution. They conducted large blocks of regional gradient array IP and three main phases of drilling ranging from 400 m x 100 m RAB with follow-up AC down to
50 m x 25 m RC and RC with DC tails, dependent upon results discovered.

Cora acquired the Sanankoro Permit in April 2017 and started exploration termite sampling in May 2017. Chris Barrett SRK UK - Principal Exploration Geologist visited Sanankoro from 27 to 30 March 2017 to bless the deal. SRK UK, however, never returned to site to do any Competent Person due diligence for the 2019 MRE, due to security concerns.

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 2 km wide Sanankoro Shear Zone, which can be traced over 30 km 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 northeast-southwest focused zone of en-echelon veining and associated sulphide development.

There are five main areas which currently define the Sanankoro Gold project, which in order of significance are Selin, Zone A, Zone B, Zone B North, and Zone C.

Selin is hosted on the eastern margin of the Sanankoro Shear Zone in the north-eastern corner of the Sanankoro permit. The Selin deposit has a typical interference node control but with the additional positive impact of a strong, rheological diorite intrusive host. The gold geology at Selin is anchored along this linear, en-echelon or possibly folded, diorite igneous intrusive which cores the volcaniclastic thrust assemblage and focuses the gold deposition.

Recent core drilling into Selin has enlightened the genetic model for this resource deposit by discovering four to six multiple early/pre-D3 dykes of diorite intruding the 65-80° west dipping axial trace of a western hangingwall F3 anti-form on this major reactivated D2 east-verging thrust. The >100 m wide Selin Shear Zone may be a regional back-thrust and the dominant eastern margin of the regional west-verging Sanankoro Thrust. The largest diorite unit is demonstrably discordant and sits immediately west and adjacent to a major early ductile, 10-30 m wide footwall carbonaceous shear. Progressive deformation has folded, warped and possibly cross-faulted the diorite units prior to gold deposition. The early footwall shear fabrics are overprinted by later semi-brittle to brittle graphitic faults which locally convert all protolith to graphitic schist on sub-metre scale. The diorite units exhibit multi-phase veining interference and sulphide development. The dominant sulphide is pyrite with occasional arsenopyrite and a scattering of chalcopyrite. Alteration minerals are predominantly sericite, silica, fuchsite, ankerite, graphite and calcite.

Zone A shores up the southern limit of the 11.5 km mineralised corridor, which forms the backbone to the Sanankoro Project. Zone A is the southern-most expression of the 010° trending central axis of the Sanankoro Shear Zone, which sits 900 m west of the Selin Boundary Shear and hosts the 5.8 km 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 strike extension of Zone A, located 800 m to the north. The Sanankoro Main Trend runs for 6 km 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, hangingwall 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.

Zone C is located 650 m southwest of Zone A on the parallel, >7 km long Sanankoro West Shear Zone (SWSZ) which can be traced along a chain of surface workings to the Excavator Prospect, 1.5 km north-northwest of Target 3. The SWSZ is high in the priority list for drilling in the 2022 program and a number of SWSZ targets, beyond Zone C, will be tested for surface 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 (>120 m from surface). There is a highly evolved weathering profile with a pronounced 8-10 m thick duricrust-laterite ferro-cap, grading downward into a well-developed mottled zone to 20-25 m depth and remains highly weathered until beyond 140 m vertically within the central mineralised fault zone. Zone B1 has extremely deep weathering with shallow oxide densities measured to depths of 190 m down-dip within the ore zone trough.

All 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.

Significant intercepts that form the basis of the MRE have been released to the AIM in previous announcements (available on the Cora website) with appropriate tables incorporating Hole, Easting, Northing, From, Depth and Intercept Assay Data.

Appropriate maps and plans accompany these Exploration Results.

Previous drilling completed by Cora, Gold Fields and Randgold is documented herein and in the publicly available report "Sanankoro Gold Project, Mineral Resource Estimate" prepared by CSA Global UK and dated January 2022.

A complete listing of all drillhole details is not necessary for this release which describes the intersections of the latest drill programme. In the Competent Person's opinion the exclusion of this data does not detract from the understanding of the Exploration results contained herein.

The 2021 programme twinned important historical Goldfields and early Cora Gold, smaller diameter, AC and RC intercepts. Historical Energold DD NQ core holes exhibited sections of unacceptably poor recoveries, especially in the deeply oxidised deposits of Zone A and Zone B1, which were twinned using the deep RC rig.

All RC intersections are sampled and assayed on 1 m intervals but could be composited up to 4 m in areas interpreted to be barren.

Significant intercepts have previously been reported using a cut-off grade of 0.5 g/t, without top cuts.

Mineralised intervals are reported with a maximum of 3 m of consecutive internal dilution of less than 0.5g/t Au. Mineralised intervals are reported on a length-weighted average basis.

No metal equivalents are reported.

The orientation of the mineralised zone has been established and majority of the drilling was planned to intersect the mineralised structures orthogonally or as close as practicable.

Existing artisanal workings, buildings, sacred sites and drainage sometimes created obstacles which prevented perfect intersection and some holes were required to be drilled at less-than-ideal orientations. 

For the bulk of drillholes, site preparations were carried out and
35 m x 25 m drill spacing applied and acceptable intersection orientations were achieved.

The appropriate plans and sections are included in this document.

All grades, high and low, are reported accurately with "from" and "to" depths and "hole identification" shown.

Detailed metallurgical test work has been carried out as part of a previous scoping study. Testwork shows that the material is amenable to conventional crushing, grinding, gravity and carbon-in-leach processing. Oxide recoveries have been determined to be >95%. An updated metallurgical variability testwork program is ongoing at ALS Perth.

1.068 detailed dry bulk density determinations were conducted on all 2021 drilled core. 589 detailed UCS point load determinations were conducted on all drilled fresh core. Detailed geotechnical logging and analysis was conducted on all drill core.

Detailed regional exploration programs continue to generate new drill targets which will feed into potential Mineral Resource growth.
