    • YRC1916D: 4m @ 4.93 g/t Au from 214.4m, 5.2m @ 2.69 g/t Au from 221.7m, 4m @ 4.21 g/t Au from 235m & 13.2m @ 1.31 g/t Au from 242m
    • YRC1947D: 16.2m @ 5.58 g/t Au from 270m
    • YRC2019D: 15m @ 3.49 g/t Au from 268m including 7m @ 4.91 g/t Au from 268m
  • Results returned high-grade intersections in the CMA hanging-wall, reflecting either CMA splays or oblique S-structures:

    • YRC1883D: 1.67m @ 62.29 g/t Au from 314.80m
    • YRC1897D: 4m @ 17.09 g/t Au from 64m

    • YRC2047D: 16m @ 3.39 g/t Au from 56m including 4m @ 10.75 g/t Au from 68m

  • Perseus will use results to upgrade the CMA Underground Inferred Mineral Resource estimate to Indicated status, enabling a Pre-Feasibility Study (PFS) for an underground mining operation to be completed by late June 2022, including an initial Ore Reserve estimate.
  • Step-out drilling on the down-dip extensions of the CMA structure also returned encouraging results, including:

    • YRC1850AD: 5m @ 3.93 g/t Au from 605m and 4m @ 3.98 g/t Au from 628m
    • YRC1855D: 11.10m @ 3.39 g/t Au from 450.40m, including 5m @ 7.16 g/t Au from 452m.

Perseus’s Managing Director and CEO Jeff Quartermaine said:

“With our three gold mines, Yaouré, Edikan and Sissingué, now producing gold at an annualised rate of over 500,000 ounces per year, Perseus’s focus has turned to maintaining this level of production out to the end of the current decade and beyond.

“Our latest infill and step out drilling results from below Yaouré’s CMA open pit confirm previous drill results that indicated that material quantities of additional Indicated Mineral Resources, capable of being economically mined using underground mining methods, may be delineated.

“We are aiming to complete a Preliminary Feasibility Study of this mining operation by the end of the June Quarter 2022, however, timing of the completion of this work will depend on the ultimate footprint size of the orebody as determined by the current drilling programme.”

CMA UNDERGROUND RESOURCE DRILLING, YAOURÉ

Perseus focused recent exploration activities on the Yaouré permits at CMA Underground and CMA down-dip extensions within 2 kilometres of the Yaouré mill (Appendix 1 - Figure 1.1). Results continue to demonstrate the potential for the Company to materially grow its gold inventory at Yaouré organically, through further drilling success.

As noted in Perseus’s ASX release “Positive Exploration Results at Perseus’s Yaouré Mine” dated 14 October 2021, recent drilling at the CMA Underground prospect focused on infill drilling to firm up previously defined underground resources extending below the currently planned CMA pit. Perseus defined an Inferred Mineral Resource of 1.8 million tonnes grading 6.1 g/t Au, extending to a maximum 275 metre down dip beneath the open pit resource (refer Resources and Reserves ASX announcement 24 August 2021), with potential to extend mineralisation further down dip beyond this (Appendix 1 – Figure 1.2). Perseus has also completed a Scoping Study which identified the potential to mine the CMA structure using underground mining methods (refer to “Perseus Mining Completes Scoping Study for Potential Underground Mine at Yaouré” dated 5th November 2018).

Following completion of drilling within the cutback zone of the CMA South open pit, Perseus extended infill drilling north along the CMA structure where grades are generally higher than at the southern end. Drilling during the last quarter comprised 12,437 metres in 56 reverse circulation (“RC”) pre-collared diamond (“DD”) holes, infilling the existing 50 x 50 metres coverage to a nominal 25 x 25 metres pattern to allow conversion of the Inferred resource to Indicated. Results continued to provide encouragement, with intercepts generally consistent with those previously encountered in both thickness and grade (Appendix 1 - Figures 1.3-1.4). Of note has been the presence of 2-3 stacked lodes in places, either as a result of anastomosing of the main lode or structural repetition. This feature has also been noted in the open pit workings, locally significantly increasing the ounces of gold per vertical metre.

The style of mineralisation remains consistent with that encountered previously, comprising pervasive, moderate to strong, pink-pale brown albite and carbonate alteration developed within a well-defined structure marked by quartz carbonate veins, fault veins, multi dilatant fault breccia, cataclasis and shearing.

Better intercepts from the CMA infill drilling are shown in Table 1 below, with a complete summary of significant results included in Appendix 2 Table 2.1.

CMA down-dip DRILLING, YAOURÉ

Perseus stepped up drilling to investigate the next 300 metre down-dip from the current CMA Underground resource, with 9,511 metres drilled in 18 RC pre-collared DD holes. This work focused within the “Magazine Zone” ahead of stocking of the magazine with explosives. The step-out program is also guided by Perseus’s early 2020 3D seismic survey that clearly identified the CMA structure extending to depth beyond the current drill coverage.

Perseus is undertaking drilling on an initial 100 x 200 metres pattern to better define the position of the CMA structure and the intensity of mineralisation. If results are encouraging, this will be infilled to 100 x 100 metres to allow an initial Inferred Mineral Resource Estimate.

Better intercepts from the Yaouré step out drilling are shown in Table 1 below and in Appendix 1 - Figures 1.5 & 1.6, with a complete summary of significant results included in Appendix 2 Table 2.2.

NEXT STEPS AT CMA

Perseus’s ongoing exploration and study programmes at Yaouré will focus on:

  • Continuation of drilling to convert the Inferred Resource at CMA to an Ore Reserve to be potentially exploited by underground mining methods and drilling down dip of the Inferred Resource to identify the potential for further resource extensions.

    Perseus is completing drilling to convert the Inferred CMA resource to an Ore Reserve as the first part of a Pre-Feasibility Study (PFS). Geotechnical, hydrological, mining and metallurgical studies have commenced as drilling and assaying results become available. Target completion for the PFS remains the end of the June Quarter 2022, with timing dependent on the ultimate footprint size of the orebody.
  • Continuation of drill testing of targets generated from the 3D seismic survey, with an initial focus on near-surface targets.
  • Aircore drilling and augering at early-stage regional prospects such as Degbezere NE.

This announcement has been approved for release by Perseus’s Managing Director and Chief Executive Officer, Jeff Quartermaine.

APPENDIX 3 – JORC TABLE 1 – YAOURÉ EXPLORATION

JORC 2012 Table 1 – Section 1 sampling techniques and data

(Criteria in this section apply to all succeeding sections)

Criteria JORC Code Explanation Commentary
Sampling techniques Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.

Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.
Drilling to define underground resources at CMA Lode commenced in July 2021 and is ongoing at the date of the report to which this table refers. Drilling completed in the period to 8 January 2022 comprises:

5,675 metres of RC drilling and 16,689 metres of core drilling in 78 completed pre-collared diamond core holes, and

6.997 metres of RC drilling in 95 pre-collars drilled ahead of core drilling.

Drilling to test down-dip of the CMA Lode Inferred resource commenced in August 2021. Drilling completed in the period to 8 January 2022 comprises:

1,551 metres of RC drilling and 6,655 metres of core drilling in 16 completed pre-collared diamond core holes, and

1,622 metres of RC drilling in 18 pre-collars drilled ahead of core drilling.

RC drilling used face-sampling hammers with 136mm hole diameter. Samples were collected at one metre intervals and logged visually for recovery, sample condition (dry, damp, wet) and contamination. Sample recoveries were measured by weighing bulk recovered samples. RC samples from pre-collars where mineralisation is not expected were normally composited to 4m intervals for assaying.

Diamond drilling utilised HQ triple-tube (61.1mm Ø) drilling in weathered materials and NQ2 (50.6mm Ø) or NQ (47.6mm Ø) core in fresh rock.     
   
Drilling techniques Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). RC drilling used face-sampling hammers with 136mm hole diameter. Samples were collected at one metre intervals. RC samples from pre-collars where mineralisation is not expected were normally composited to 4m intervals for assaying.

Diamond drilling utilised HQ triple-tube (61.1mm Ø) drilling in weathered materials and NQ2 (50.6mm Ø) or NQ (47.6mm Ø) core in fresh rock. Core in fresh rock was oriented using a MAGSHOT II (Wellforce) and an ORISHOT II (Reflex) device.

Drill sample recovery Method of recording and assessing core and chip sample recoveries and results assessed.

Measures taken to maximise sample recovery and ensure representative nature of the samples.

Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.
RC drill samples were logged visually for sample condition (dry, damp, wet) and contamination. Sample recoveries were measured by weighing bulk recovered samples. Preliminary evaluation indicates that RC sample recoveries have been satisfactory. There were no wet samples logged in the CMA UG RC pre-collar holes.

Diamond core recoveries were measured linearly per drill run. Core recoveries average approximately 85% in weathered materials and 100% in fresh rock.

The Competent Person considers that there are presently insufficient data available to permit a meaningful examination of potential relationships between sample recovery and gold grade.

Logging Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.

Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography.

The total length and percentage of the relevant intersections logged.
Geological logs are available for the entire lengths of all drill holes. The logging is qualitative in nature.

Sieved samples of RC chips from each metre of drilling were logged for colour, rock type, alteration type and intensity, vein quartz content, sulphide mineralisation, weathering and oxidation. The chips are stored in plastic chip trays and the trays photographed.

Diamond drill core was logged for geology, structure and geotechnical characteristics. Geological logging included colour, lithology, weathering, oxidation, vein type and vein volume percentage, sulphide species and their estimated percentage, alteration and alteration intensity. Structural logging included fault, fold, cleavage and joint orientation, lithological contacts and vein orientations. Drill core was photographed prior to cutting.

Sub-sampling techniques and sample preparation If core, whether cut or sawn and whether quarter, half or all core taken.



If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry.

For all sample types, the nature, quality and appropriateness of the sample preparation technique.

Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.

Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling.

Whether sample sizes are appropriate to the grain size of the material being sampled.
RC drill samples were collected at drill sites over one metre intervals and manually split using multi-stage riffle splitters to produce assay sub-samples averaging around 3kg. All RC holes have been assayed in entirety. RC samples from pre-collars where mineralisation is not expected were normally composited to 4m intervals for assaying.

In weathered materials, diamond core was halved using spatulas or knives. In fresh rock, core was sawn in half using a diamond blade saw, with one half sent for assaying and the other half stored in core trays for reference. Samples were normally taken at 1 metre intervals. For CMA underground resource definition holes, only core intervals with visible alteration and mineralisation plus approximately 10m up- and down-hole were sampled. For exploration drill holes, all diamond drill core has been assayed.

All sample preparation has been undertaken at Perseus’s Yaouré sample preparation facility operated and supervised by Perseus personnel.

Preparation of core and RC samples followed a standard path of drying at 105 degrees C for at least 12 hours, crushing the entire sample to 85% passing -2mm and grinding a 1.5kg split to 85% passing 75 microns. 300g pulp subsamples are selected by multiple scoop passes.

Quality control measures adopted to confirm the representivity of samples from RC and diamond drilling include:

  • Field re-splits of RC samples at an average frequency of around one duplicate per 20 primary samples respectively.
  • Submission of coarse blanks at an average of around 1 blank per 20 primary samples
  • Use of quartz wash between every sample in crushing and pulverising equipment
  • Screening of approximately 1:20 pulp samples to check grind size
Sample preparation techniques are considered appropriate to the style of mineralisation. Available information indicates that sample sizes are appropriate to the grain size of the material being sampled.

Quality of assay data and laboratory tests The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.

For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.

Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.

All RC and diamond core samples have been assayed by 50g fire assay with AAS determination by Intertek Testing Services Ghana at their Tarkwa assay laboratory or by Bureau Veritas at their Abidjan laboratory. The technique is considered a total extraction technique.

Quality control procedures include submission of coarse blanks (1:20) and certified reference standards (1:20).

The available information indicates that the assaying of RC and core samples is free from any significant biases and is of acceptable accuracy.
Verification of sampling and assaying The verification of significant intersections by either independent or alternative company personnel.

The use of twinned holes.

Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.

Discuss any adjustment to assay data.
Numerous significant mineralised intersections have been checked against visual alteration and sulphide mineralisation in drill chips and core.

None of the holes in the report to which this table relates have been deliberately twinned.

Geology, structure and geotechnical logs are paper based. Sample intervals are recorded in pre-numbered sample ticket books. All logging, sample interval and survey data are manually entered to digital form on site and stored in an acQuire relational database. Data exports are normally in the form of MS Access files.

Data verification procedures include automated checks to:

  • prevent repetition of sample numbers
  • prevent overlap of from-to intervals in logging and sample interval data
  • ensure that total hole depths in collar, assay and geology tables match
  • ensure that drill collar coordinates are within the project’s geographic limits
Down-hole survey data are examined for large deviations in dip or azimuth that may represent erroneous data or data entry errors and corrected on a case-by-case basis including estimates of dips and azimuths where the original data appear to be in error.

Additional data checks include viewing drill hole traces, geological logging and assays in plan and section views.

Location of data points Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.

Specification of the grid system used.

Quality and adequacy of topographic control.
Drill hole collars have been surveyed by qualified mine surveyors using differential GPS equipment with coordinates recorded in UTM grid, WGS84 Zone 30N datum.

All RC and diamond core holes have been surveyed at 12m depth and at approximately 30m down-hole increments using digital compass instruments.

A topographic surface has been established by a LiDAR survey conducted in 2017. The topographic surface is reliable to +/- 0.2m.

Topographic control is adequate for the current work being undertaken at Yaouré.

Data spacing and distribution Data spacing for reporting of Exploration Results.

Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.

Whether sample compositing has been applied.

The CMA Lode is delineated by regular drilling at 50mN x 25mE spaced holes to between 150 and 200 metres below natural surface. Partial coverage at 50mN x 50mE spacing extends to between 200 and 275 metres below surface. Holes have generally been drilled dipping at -55 to -75 degrees toward 270 degrees (UTM grid) azimuth.

Orientation of data in relation to geological structure Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.

If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.

Drill holes are oriented approximately orthogonal to the dip and strike of the CMA Lode. Drill intercept lengths closely approximate true widths of mineralisation.

The relationship between drill intercept lengths and true widths of mineralisation in the CMA East Seismic Target area is not known at the time of this report.
Sample security The measures taken to ensure sample security. RC and core samples were delivered to the secure core yard compound at Yaouré mine by Perseus personnel. RC field sample splits and samples of half diamond core were placed in numbered bags and those bags, in turn, placed into polywoven sacks that were closed with plastic cable ties prior to transport to the Yaouré sample preparation facility by Perseus personnel. Security guards were employed at drilling sites, the core yard compound and the sample preparation facility on a 24 hour per day basis.

Results of field duplicates along with the general consistency of assay results between neighbouring drill holes and drilling methods provide confidence in the general reliability of the assay data.

Audits or reviews The results of any audits or reviews of sampling techniques and data. The Yaouré sample preparation facility has previously been subject to formal audit, the last being in 2017. Standard operating procedures have not changed materially since that audit.

The Competent Person has reviewed the available sampling and assaying quality control data and found no errors or bias likely to significantly affect the reliability of the exploration data. These reviews included review of database consistency, comparisons between database records and laboratory source files, and review of QAQC information.

The Competent Person considers that the sample preparation, security and analytical procedures adopted for the CMA resource drilling provide an adequate basis for the reporting of Exploration Results.

JORC 2012 Table 1 – Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section)

Criteria JORC Code explanation Commentary  
Mineral tenement and land tenure status Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.
The drill holes discussed in the report to which this table relates are located within the Yaouré exploitation permit (PE50). The permit has an expiry date of 23 April 2030. The permit is held by Perseus’s subsidiary Perseus Mining Yaouré SA in which the government of Côte d’Ivoire holds 10% free carried interest.  Additionally, the Government of Côte d’Ivoire is entitled to a royalty on nett revenue (revenue minus transport and refining costs) as follows:



 
    Spot price per ounce - London PM Fix Royalty Rate
    Less than or equal to US$1,000 3%
    Higher than US$1,000 and less than or equal to US$1,300 3.5%

    Higher than US$1,600 and less than or equal to US$2,000 5%
    Higher than US$2,000 6%
       
    A further 0.5% of nett revenue is required to be paid to a local community development fund.

The reported exploration areas have no known exploration-specific environmental liabilities.

Exploration done by other parties Acknowledgment and appraisal of exploration by other parties. Exploration geochemical sampling, trenching and exploration and resource definition drilling have previously been carried out by BRGM, Cluff and Amara.  Drill hole data deriving from work by Cluff and Amara are considered reliable.

Geology Deposit type, geological setting and style of mineralisation. Yaouré may be described as orogenic lode-style gold mineralisation. The Yaouré project comprises two adjacent deposits, Yaouré and CMA, that occur near the south-eastern flank of the Bouaflé greenstone belt in central Côte d’Ivoire. Mineralisation is hosted by Paleoproterozoic aged metabasalts and felsic intrusive rocks of the Birimian Supergroup. The rocks are metamorphosed to lower greenschist facies and only locally feature penetrative deformation fabrics.

In both deposits, gold is associated with disseminated pyrite. At CMA deposit, mineralisation is associated with quartz-albite-carbonate veining in reverse fault structures that dip at 25 to 35 degrees to the east. Yaouré deposit comprises several mineralisation styles controlled by east-dipping structures, similar to CMA, in addition to mineralisation associated with quartz-tourmaline-chlorite-carbonate veining controlled by NE and NW striking, sub-vertical faults and also stockwork quartz veins with associated alteration selvages hosted by a granodiorite intrusive body.

The combined deposits extend over an area around 1.4 km east west by 2.1 km north-south.

Drill hole Information A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
  • easting and northing of the drill hole collar
  • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
  • dip and azimuth of the hole
  • down hole length and interception depth
  • hole length.
If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

A table of drill hole and intercept details is included in the report to which this table relates.
Data aggregation methods In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.
Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
The assumptions used for any reporting of metal equivalent values should be clearly stated.

The cut-off grade, minimum down-hole length and maximum included internal waste are clearly stated in the report to which this table relates.
Higher-grade “included” intercepts are clearly reported.
Drill hole intercepts have not been reported as metal equivalents.
     
Relationship between mineralization widths and intercept lengths These relationships are particularly important in the reporting of Exploration Results.
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’).

The geometry of the CMA Lode has been clearly demonstrated by previous drilling. The lengths of drill intercepts of that structure in the report to which this table relates closely approximate true widths.

 

The relationship between drill intercept lengths and true widths of mineralisation in the CMA East Seismic Target is not known at the time of this report.
Diagrams Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

Appropriate plans and sections are included in the report to which this table relates.
Balanced reporting Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.

Holes that did not intercept significant mineralisation are shown on plans and cross-sections and “NSI” holes are included in tables of intercepts.
Other substantive exploration data Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. The Yaouré property has been subject to extensive exploration, including:

  • Soil sampling, surface mapping
  • Approximately 300,000 metres of drilling
  • Previous mining by Compagnie Miniere d’Afrique (CMA) and Cluff Mining
  • Airborne EM, gravity, radiometrics and magnetic surveys
  • 2D & 3D seismic surveys.
 

 The CMA Lode is presently being exploited by open pit mining.

Further work The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).
Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.

Perseus intends to continue drilling at CMA to delineate an Indicated Mineral Resource and to undertake such studies as are required to complete an economic evaluation of material that may be exploited by underground mining.
