ASX RELEASE | 6 October 2021 | ASX: AON
SHALLOW HIGH-GRADE MINERALISATION EXTENDS FOOTPRINT AT DIKAKI
DRILLING TO THE SOUTH AND EAST OF PREVIOUS DRILLING CONFIRMS MINERALISED EXTENSIONS
Apollo Minerals Limited (“Apollo Minerals” or the “Company”) is pleased to report additional results received from the drilling program at the province-scale Kroussou zinc-lead project (“Kroussou Project” or “Project”) in Gabon.
Highlights:
-
Results have been received from a further 14 diamond drill holes completed at the Dikaki and Bouambo Prospects, two of 18 highly prospective prospects at the Project.
-
At Dikaki the main channel-wide system is untested for >8km along trend by modern drilling with an average channel width of 420m.
-
Average depth to mineralisation <10m for reported main zones of mineralisation.
-
The results demonstrate the potential of the eastern and central Dikaki zones merging with significant shallow, intercepts including:
-
20.9m @ 2.6% Zn+Pb from 32.4m
- including 6.2m @ 5.3% Zn+Pb from 47.1m; and 2m @ 5.3% Zn+Pb from 32.4m
-
18.9m @ 2.2% Zn+Pb from 1.2m
-
including 5m @ 5.0% Zn+Pb from 1.2m
-
open for 400m on section to the south, and untested 530m along trend to the westsouthwest
-
-
17.3m @ 2.4% Zn+Pb from 37.2m
- including 4.9m @ 3.2% Zn+Pb from 37.8m; and 6.4m @ 2.9% Zn+Pb from 48.2m
-
20.0m @ 2.0% Zn+Pb from 13.5m
-
including 9.3m @ 2.4% Zn+Pb from 13.5m
-
open for 320m on section to the south and >2km along trend to the east
-
-
New drill holes show significantly higher endowment (up to seven times) when compared to the insufficiently sampled nearby historical drilling – highlighting the strong upside potential of the whole Dikaki system.
-
Diamond rigs will shortly move back to Dikaki to test the central to eastern zone linkage.
-
The results continue to support the potential for a large-scale, shallow, flat-lying, broad mineralised system with possible continuity across multiple zones which could allow simple open pit mining extraction.
-
Strong news flow and further results expected in coming weeks with assays pending from the remaining 11 holes completed at Dikaki, and additional holes from the ongoing drilling at the Niamabimbou Prospect.
-
The Kroussou Project represents a significant, large scale, near surface zinc-lead (“ZnPb”) project with more than 80km of strike length , 18 key prospects , and multiple opportunities for further discovery .

Apollo Mineral’s Executive Director, Mr Neil Inwood, commented “The latest results at Dikaki demonstrate the strong potential for both the linking of the eastern and central mineralised zones and for the mineralisation to extend across the whole channel width. The assay results also highlight the significant upside potential in the system, where modern drilling is demonstrating significantly more mineralisation than the historical BRGM drilling (locally up to 700% more). Our maiden drill campaign at Dikaki is continuing to demonstrate the developing potential for a large and shallow channel of mineralisation averaging 420m in width and up to 6km in strike that could be amenable to simple low-cost open pit mining. The Kroussou Project has the potential to deliver a significant, large scale, base metal province.”

PHASE 1 DRILL PROGRAM AT DIKAKI
Exploration drilling at the Kroussou Project to date has focused on the Dikaki Prospect and the newly discovered Niamabimbou Prospect situated approximately 10km to the south of Dikaki. This announcement focuses on the completed Phase 1 drilling from Dikaki and the nearby Bouambo Prospect.
The Phase 1 drilling program at the Dikaki and Bouambo Prospects consisted of 46 diamond drill holes for 2,206m. Assays have now been received from 37 drill holes, with the latest 14 being reported in this announcement. Drilling at Niamabimbou is continuing, and results will be released in the coming weeks.
The assay results from Dikaki continue to demonstrate extensive high-grade zinc and lead mineralisation and the potential for a large-scale, shallow, flat-lying, broad mineralised system .
Dikaki is situated at the centre of the Kroussou project area and represents one of four prospects with historic drilling activity (Figure 1). Apollo Minerals’ diamond drilling within the eastern and central zones at Dikaki was designed to test for the presence of mineralisation near historic exploration conducted by the French Bureau de Recherches Géologiques et Minières (“BRGM”). Historic drilling completed by BRGM at Dikaki identified a variety of mineralisation styles, but the holes were either not sampled or only character-sampled (i.e. only select visually identifiable intervals were sampled, often ending in significant mineralisation) (Figures 3 and 4).
Mineralisation at Dikaki is shallow (0-30m from surface) with mineralisation up to 40m thick (estimated true thickness); this geometry of mineralisation is interpreted to be favourable to potential shallow, open-pit mining scenarios.
Significantly, two of the holes in the current announcement (DKDD061 and DKDD062) have demonstrated shallow metal accumulations of greater than 40%m (Zn+Pb% x thickness) (Figure 2). These metal accumulations demonstrate the significant metal potential within the Dikaki mineralised system; particularly in areas where there was no previous drilling (e.g. DKDD061), or where historical drilling significantly under called the mineralisation due to character sampling (e.g. DKDD062).
DKDD0062 intersected 18.9m @ 2.2% Zn+Pb from 1.2m, including 5m @ 5.0% Zn+Pb from 1.2m ; the nearby historical BRGM hole DK032, located 12m away, was character sampled based upon visual identification of sulphides and reported only 1.6m @ 3.6% Zn+Pb. This significant difference in identified mineralisation (~ 700% increase ) highlights the strong exploration potential within the broader Dikaki system.
The continued trend of modern drilling significantly exceeding the historical BRGM drill results has the impact of increasing the exploration potential of areas which were previously lower-ranked due to reliance on the under-sampled historical BRGM drill holes.
The latest results show significant intersections that have been recorded at shallow depths (from 1.2m), with thicknesses up to 22m, in the 12 drill holes reported herein. Select intercepts include:
-
20.9m @ 2.6% Zn+Pb from 32.4m in DKDD079
-
including 6.2m @ 5.3% Zn+Pb from 47.1m; and 2m @ 5.3% Zn+Pb from 32.4m
-
18.9m @ 2.2% Zn+Pb from 1.2m in DKDD062
-
including 5m @ 5.0% Zn+Pb from 1.2m
-
open for 400m on section to the south, and untested 530m along trend to the westsouthwest
-
17.3m @ 2.4% Zn+Pb from 37.2m in DKDD077
-
including 4.9m @ 3.2% Zn+Pb from 37.8m; and 6.35 @ 2.9% Zn+Pb from 48.2m

==> picture [88 x 39] intentionally omitted <==
-
20.0m @ 2.0% Zn+Pb from 13.5m in DKDD061

open for 320m on section to the south and >2km along trend to the east
The locations of the reported drill holes, along with their accumulated intercepts shown as grade times thickness (Zn+Pb % x thickness in metres) are shown in Figure 2 overpage. All significant intersections within the new drill holes, along with the details of the collar position, drill hole orientation and depth, are summarised in Appendix 1.

CURRENT EXPLORATION ACTIVITIES
First stage drilling at the Niamabimbou Prospect has now finished, with a total of 40 holes for 2,088m. The rigs have now returned back to Dikaki for the remainder of the 2021 field season (expected to finish in late-October).
The majority of holes drilled at Niamabimbou to date have intersected visible Zn-Pb sulphide mineralisation, as observed by in-field drill core logging, with visual identification of up to 8% galena (lead sulphide) content recorded locally ( refer ASX announcement dated 30 August 2021 ).
The presence of shallow, base metal sulphide mineralisation in the majority of holes logged at Niamabimbou validates the Company’s exploration targeting model. The geological logging of the drill holes is showing potential for: a) coherent distinct sedimentary units that are hosting mineralisation in a similar geometric pattern to that observed at Dikaki; and b) coherent mineralisation footprint across the entire channel. The various styles of mineralisation encountered to date in the Niamabimbou drilling also show similarities to those observed at Dikaki (Figure 5).
The Niamabimbou Prospect alone has over 9km of prospective trends for Zn-Pb mineralisation (Figure 6).
Regional geological mapping and soil sampling activities are also underway in the southern portion of the Project, and a passive seismic survey is also expected to commence in the coming weeks.
The ongoing drilling and field exploration activities at the Kroussou Project will continue to generate strong news flow during the upcoming December quarter.

ABOUT THE KROUSSOU PROJECT
The Kroussou Project (Figures 1 and 7) consists of the Prospecting License G4-569 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 well-maintained 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 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. ½ core samples were assayed at Intertek Perth where the entire sample was crushed, and a charge digested by ore grade multi-acid digest and analysed by ICP-MS or ICP-OES |
| 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 drilling contactors.. 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 obtain 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 firm relationship between recovery and grade has been identified to date; however it is noted that poor recovery can occur near some high-grade intercepts, with indications from the outside return of the rig indicating that mineralised material is being lost. Further investigation is required. |

| 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 introduced a sampling bias, this should be assessed and reported if material. |
This is not currently considered material. | |
| Sample security |
The measures taken to ensure sample security. | All core sample intervals are labelled in the core. Cut core samples are collected in bags labelled with the sample number and a sample tag. Samples are delivered to the Intertek, Libreville sample preparation facility directly by AON personnel or transport contractors. The samples were then transported to the Intertek Genalysis Laboratory in Perth for geochemical analysis. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |
All QAQC data is reviewed to ensure quality of assays; batches containing standards that report greater than 2 standard deviations from expected values are re-assayed. |

| Exploration done by other parties |
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. |
|
| Geology | Deposit type, geological setting and style of mineralisation. |
The deposit style reported in BRGM historical files is Mississippi Valley Type (MVT) sedimentary mineralisation of Pb-Zn-(Ag) where mineralisation is similar to the Laisville (Sweden) style with deposition within siliciclastic horizons in a reducing environment. On a regional scale, the Pb-Zn mineral concentrations are distributed at the edge of the continental shelf which was being eroded during 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. |

| 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: o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevationabove sea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho hole length. |
All new drill hole details are provided in Appendix 1. | |
| 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. |

| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. |
Significant intercepts are reported as down-hole length- weighted averages of contiguous grades above approximately 0.5% Zn+Pb and above a nominal length of 1m. No top cuts have been applied to the reporting of the assay results. Overall sample recovery is predominantly > 90%; intervals with no sample recovery have not been diluted in the compositing process. |
|
| 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 |
Higher grade intervals are included in the reported grade intervals; and have also been split out on a case-by-case basis where relevant.. |

| examples of such aggregations should be shown in detail. |
|||
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalent values are used. | ||
| Relationship between mineralisation 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. |
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. |
|
| 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. |
All meaningful and material information is reported. | |
| 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. |
