Drilling at Niamabimbou is targeting shallow, high grade zinc-lead ( Zn-Pb ) mineralisation.
-
Widespread high-grade mineralisation was identified in the 2020 sampling program, with grades of up to 24.85% combined Zn-Pb from rock chip samples.
-
Strong news flow expected shortly as results from the ongoing drilling programs at the Dikaki and Niamabimbou prospects continue to delineate the scale of the project.
-
The Kroussou Project represents a significant, large scale, shallow Zn-Pb project with more than 80km of strike length of prospective contact, 18 target Prospects , and multiple opportunities for discovery indicated by soil and rock chip sampling.
Apollo Mineral’s Executive Director, Mr Neil Inwood, commented “The confirmation of base metal sulphides at shallow depths in the maiden drilling program at Niambabimbou confirms the prospectively of both the large Niamabimbou Prospect area and the broader Kroussou Project (over 80km of prospective strike length and 18 identified Prospects). The Company eagerly awaits the results of this first ever drilling at Niamabimbou.”

DRILLING AT NIAMABIMBOU
Drilling at the Niamabimbou Prospect commenced in July 2021 and focused on drill testing multiple targets defined by mapping and rock chip sampling (Figure 2). The overall drill program comprises approximately 100 holes for 5,000 metres of diamond drilling.
This program represents the first ever drilling at Niamabimbou , which is developing into a potential new discovery with significant scale including a prospective strike length of ~8km.
The Niamabimbou drill program is based on targeting derived from mapping and rock chip sampling completed in 2020. This work was successful in refining the interpreted geology of the sedimentary channels (Figure 2) and generated numerous new high priority drill targets, with the potential to host significant tonnage of shallow base metals mineralisation (refer ASX announcements dated 15 January 2020 and 11 May 2020 ).
To date, 19 drill holes for 970m have been completed at Niambimbou (Figure 2), with two rigs currently deployed at the Prospect. The majority of holes drilled have intersected visible ZnPb sulphide mineralisation, as observed by in-field drill core logging, with visual identification of up to 8% galena (lead sulphide) content recorded locally (e.g. NBD0006 23.90m-24.25m).
These first drill holes at Niamabimbou have targeted the northern region of the Prospect, and cover only approximately 1.5km of the ~8km prospective trend. Four other priority target areas are still to be drill tested at the Prospect. Based on visual observations from the drilling completed to date, a mineralised trend of up to 1.3km is being indicated in this initial target area ; with the remaining ~7km of prospective trend at the Prospect still to be tested in this program.
The presence of shallow, base metal sulphide mineralisation in the majority of holes logged validates the Company’s exploration targeting model . The initial geological logging of the drill holes is also showing potential for: a) coherent distinct sedimentary units that are hosting the mineralisation in a similar geometric pattern to that observed at Dikaki; and b) coherent mineralisation footprint across the entire channel (Figures 2 and 3).
Intervals of Zn-Pb sulphide mineralisation have been identified using a combination of visual identification, with assistance of a hand-held XRF (‘pXRF’ readings) and indicates the presence of broad mineralisation ranging from 2 to 20m true thickness. These intervals contain observed sulphide mineralisation between 0.5% to 8.0% Zn-Pb sulphide content (sphalerite + galena) in holes (NBDD001, 2, and 4-16, see Table 1) typically in the range of 1 to 4% sulphides, with localised intervals of more intense mineralisation (2-8% Zn-Pb sulphide content over 0.2 to 4.0m) that form part the broader mineralised packages.
The various styles of mineralisation encountered to date include coarse galena veinlets associated with cavities/fractures, disseminated galena and sphalerite (zinc sulphide) within sandstones, and coarse galena veinlets and fine-grained sphalerite associated with carbonate lithologies (Figure 4).
It is important to note that both the visual identification of sulphide mineralisation, and the use of a hand-held XRF, are empirical methods of mineralisation identification; and that final laboratory analysis of the drill core samples is required to demonstrate actual Zn-Pb grades . Assays are pending from this drilling and results are expected in the coming weeks.

Niamabimbou Prospect Geology and Targeting
Drill targeting at Niamabimbou includes a focus on defining mineralisation around broader channel targets, as well as interpreted horst related faulted ‘weir’ outcrops.
The ‘weir’ targets are indicated in four areas where a dominance of conglomerate and/or microconglomerate outcrop has been mapped. These outcrops have been interpreted as a shallow underlying basement, compared to the other parts of the channel where sandstone and siltstone are dominant lithologies. These ‘weirs’ are potentially the result of fault-related horst type features in the basement and their external margins are considered favourable geomorphologic settings for potential high-grade mineralisation in part due to the presence of clastic sediments.
Mineralised outcrops identified on the weir margins represent priority drilling targets, particularly in the zones “Wr2” and “Wr3” (Figure 2). High priority drilling targets were also identified at Niamabimbou NE (NB-NE) where a zone of mineralised outcrops (including JBR049 and JBR069 which returned 7.14% and 8.15% combined Zn-Pb respectively) extends 400m by 150m, with potential extending down-dip and laterally to the south and west. Recent results of soil geochemistry in this area delineated a significant Zn-Pb anomaly approximately 1.5km long by 200m wide.
ABOUT THE KROUSSOU PROJECT
The Kroussou Project (Figure 5) consists of the Prospecting License G4-569 (the Company recently applied for the extension of the Prospecting Licence) which covers 986.5km[2] in the Ngounié Province of Western Gabon located approximately 220km southeast of the capital city of Libreville. The project is easily accessible by the major sealed N1 road from Libreville, and wellmaintained provincial roads to towns bordering the project. Well-established and wide forestry tracks are present within the project area to the camp and exploration sites.
Zn-Pb mineralisation is hosted in Cretaceous sediments on the margin of the Cotier Basin within preserved channels lying on unconformable Archaean and Paleoproterozoic basement rocks.
Historical exploration work at the Kroussou Project identified 150 base metal occurrences along a +80km strike length of prospective geology within the project area. The Zn-Pb mineral occurrences are hosted within exposed channels that offer very shallow, near surface targets close to the basement rocks.
Only two of the 18 exposed channels were drill tested by the Bureau de Recherches Géologiques et Minières ( BRGM ) historically, with both channels containing significant base metal mineralisation. A further two near surface targets were drilled by Trek Metals Limited ( Trek ), which also returned significant Zn-Pb intervals, further validating the province scale, base metal potential of the project area.
There are multiple opportunities for the discovery of further base metal mineralisation within the remaining untested 14 channels and also further exploration westward within the broader Cotier Basin is warranted.

JORC Code, 2012 Edition – Table 1 Report
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 (eg 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. |
Diamond Core was cut in half to produce a ½ core samples using a core saw - DDH. All sampling was either supervised by, or undertaken by, qualified geologists. Drill core was scanned for 30 seconds every 20cm by NITON XRF for the entire length of the drill hole. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Drill hole locations were surveyed using standard Garmin GPS equipment achieving sub metre accuracy in horizontal and vertical position. Sampling was carried out under the AON protocols and QAQC. See further details below. |
|
| 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. |
Half-core samples are selected based on geological criteria (presence of sulphide mineralisation). |
|
| Drilling techniques |
Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). |
HQ-sized (63.5 mm diameter) and NQ size core drilling has been completed by FGSD Drillers. All drilling is vertical. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
Drill hole recoveries were recorded during logging by measuring the length of core recovered per 1m interval. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
Drilling is carried out vertical and orthogonal to the mineralization to get representative samples of the mineralization. |
|
| 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. |
No relationship between recovery and grade has been identified to date in the data review stage. |
|
| 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. |
All drill core was logged onsite by geologists 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. |
Logging is qualitative and records lithology, grain size, texture, weathering, structure, alteration, veining, and sulphides. Core is digitally photographed. |
|
| The total length and percentage of the relevant intersections logged. |
All holes are logged in full. | |
| 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. |
Core is cut using a diamond saw and ½ core is submitted for assaying. |

|
| 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. |
GPS coordinates of drill hole locations were captured using a Garmin GPS in UTM WGS84 Easting/Northing coordinates with metric accuracy in horizontal and vertical position. |
| Specification of the grid system used. | Sample locations are provided as UTM co-ordinates within Zone 32, southern hemisphere using WGS 84 datum. |
|
| Quality and adequacy of topographic control. | Topographic control is based on topographic contours sourced from SRTM data. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. | Drill hole spacing for the 2021 drill program is variable as most drilling to date is either first pass drilling of new exploration targets or step- out brownfields exploration targeting along strike from existing intercepts. |
| 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. |
Further work is required at the Project to test for extension of mineralisation potential and verification of historical collars. Some drilling is on a spacing which is sufficient to test the grade continuity of mineralisation for this style of mineralisation. The current data set is considered potentially appropriate for use in a future Mineral Resourceprovidingfurther drillingis completed. |
|
| Whether sample compositing has been applied. | No compositing of samples in the field was undertaken. | |
| 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. |
It is considered the orientation of the bulk of the drilling and sampling suitably captures the dominant “structure” of the style of mineralisation at the Project. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have |

Acknowledgment and appraisal of exploration by other parties. |
Intermittent historical exploration as conducted by French Bureau de Recherches Géologiques et Minières (BRGM) at Kroussou from 1962 - 1963, the project was then later re-examined in 1979-1981 by the BRGM in joint venture with Comilog which is a Gabonese government owned mining company. BRGM discovered the Kroussou Pb-Zn-(Ag) mineral occurrences as well as others along various river systems on the Kroussou license. BRGM conducted drilling on the project in 1962 and 1977-1980. Metals of Africa (renamed Battery Minerals) obtained historical reports and drill logs relating to BRGM’s field program and completed cursory rock chip and mapping work in 2015 and 2016. Trek completed soil surveying, mapping, rock chip sampling, ground geophysics and two drilling programs to confirm historical results during 2017 and 2018. |

| Lower Cretaceous time. Mineralisation is located within the Gamba Formation part of the N’Zeme Asso Series and was deposited during the Cretaceous as part of the Cocobeach Complex deposited during formation of the Cotier Basin. Mineralisation is hosted by conglomerates, sandstones and siltstones deposited in laguno-deltaic reducing conditions at the boundary of the Cotier Basin onlapping continental basement rocks. Large scale regional structures are believed to have influenced mineralisation deposition. |

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. |
Down-hole lengths are reported. The exploration drilling was conducted so that results would be close to orthogonal to the mineralisation as understood at the time. As such, the intercepts are interpreted to be close to true thickness of the mineralization. |
|
| If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
|||
| 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 diagrams, including geological plans, are included in the main body of this release. |
|
| 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. |
The exploration results should be considered indicative of mineralisation styles in the region. Exploration results stated indicated highlights of the drilling and are not meant to represent prospect scale mineralisation. As the projects are brownfields exploration targets, and there are large numbers of holes drilled over the region, it is considered appropriate to illustrate mineralised and non-mineralised drill holes by the use of diagrams, with reference to the table of significant intercepts. |

| Further work The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step- out drilling). |
Infill and extensional drilling at the Dikaki Prospect and initial drilling testing at the Niamabimbou Prospect. Additional surface exploration programs comprising soil surveying, geological mapping, rock chip sampling to further assess identified prospects and to generate new targets within the broader project area. Further drill testing of multiple exploration targets across the project area following after ranking and prioritisation. Additional metallurgical test work over all prospective targets to assess recovery characteristics, concentrate quality, and variability. |
