High Grade Zinc-Lead Sampling Results at the Kroussou Project
(firmenpresse) - Apollo Minerals Limited (Apollo Minerals or Company) is pleased to report the results of a recent surface exploration program undertaken at the Kroussou zinc-lead project (Kroussou Project or Project) in western Gabon.
Highlights:
- A program of geological mapping, rock chip and soil sampling was carried out across three target Prospects within the Kroussou Project, including the high priority Niamabimbou Prospect (~8km strike length of prospective geology)
- Rock chip samples collected from the Niamabimbou Prospect identified widespread high grade zinc-lead mineralisation with grades up to 20.16% combined Zn-Pb
- Best results from the sampling program at the Niamabimbou Prospect include:
o 20.16% combined Zn-Pb from sample JBR246
o 15.20% combined Zn-Pb from sample JBR244
o 10.71% combined Zn-Pb from sample JBR136
o 8.15% combined Zn-Pb from sample JBR069
o 7.98% combined Zn-Pb from sample JBR201
o 7.84% combined Zn-Pb from sample JBR131
o 7.14% combined Zn-Pb from sample JBR049
- Mapping has identified multiple new zones of mineralised outcrops extending over wide areas, each representing an exploration target with the potential to host significant shallow, zinc-lead mineralisation
- Soil sampling grids were completed at the Niamabimbou, Dignali and Ofoubou Prospects, with the results pending
- Exploration to date continues to validate the province-scale base metals potential of the Project
- Only four of the 18 prospects have been drill tested to date, with all four channels intersecting zinc-lead mineralisation at very shallow depths
- Multiple opportunities for discovery with all 18 prospects remaining open and under-explored, with broader, deeper parts of the basin to the west completely untested
- Positive initial metallurgical test work has confirmed high recoveries and produced separate, high grade and high-quality zinc and lead concentrates with very low deleterious / penalty elements
- Drilling programs are being designed to focus on defining sufficient shallow (open-pittable), high grade zinc-lead mineralisation to justify commencement of feasibility studies
- Drill rigs will be mobilised to site in the coming months

KROUSSOU PROJECT OVERVIEW
The Kroussou Project consists of the Prospecting License G4-569 which covers 986.5km2 in the Ngounié Province of Western Gabon located approximately 220km southeast of the capital city of Libreville (Figure 2).
Zinc-lead mineralisation is hosted in Cretaceous sediments on the margin of the Cotier Basin within preserved channels lying on unconformable Archaean and Paleoproterozoic basement rocks (Figures 3).
Historical exploration work at the Kroussou Project identified 150 base metal occurrences along a +70km strike length of prospective geology within the project area.
The zinc-lead 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 zinc-lead 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.

Reconnaissance Geological Mapping and Sampling Programs
Two phases of geological mapping, rock chip and soil sampling were completed late in 2019. The mapping and sampling programs were designed to identify new targets for base metals mineralisation for future drilling campaigns, and to further interpret regional geology within sedimentary channels.
Sampling occurred at the Niamabimbou, Ofoubou and Dignali Prospects (Figure 3) and a selection of 75 mineralised rock samples were sent to the Intertek laboratory in Libreville for sample preparation before being sent to the Intertek Genalysis laboratory in Perth for assaying.
Niamabimbou Prospect
At Niamabimbou, a total of 556 points of observation were mapped, 92 outcrops were sampled, and 75 rock chip samples sent for analysis.
Based on the lithologies of rock samples and topographic contours the basin-basement contact was reinterpreted in some areas of the channel.
Four areas with a dominance of conglomerate and/or microconglomerate outcrops were 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 horst-type features in the basement and their external rims are considered favourable geomorphologic settings for high grade mineralisation (Figure 4).
https://www.irw-press.at/prcom/images/messages/2020/49774/200115 Kroussou Exploration Results_FINAL_v2_cleanPRcom.004.png
Figure 4: Niamabimbou Prospect Geological Map
Mineralised outcrops were identified on the rim of these weirs and represent priority drilling targets, particularly in the zones Wr2 and Wr3.
Rock samples JBR131 and JBR136 located on the northwest rim of the Niamabimbou channel, close to Wr3, returned 7.84% and 10.71% combined Zn-Pb.
The eastern rim of the channel, coincident with a northwest trending fault returned also high values with 7.98% combined Zn-Pb in JBR201, with the richest outcrops located on the external rim of Wr2 (15.20% and 20.16% combined Zn-Pb in JBR244 and JBR246 respectively).
A new target was discovered at Niamabimbou-DS (NB-DS) approximately along strike of Wr2 mapped in the central channel of Niamabimbou (assays pending). This may indicate the presence of an east-west oriented horst type feature in this area.
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.
According to the drilling programs carried out in 2017-18, clastic ore is the more favourable ore type for lenses of significant tonnage with medium/high grade. Drill targeting at Niambimbou will therefore initially focus on mineralised outcrops with clastic ore type.
An extensive program of soil sampling occurred in two phases at the Niamabimbou Prospect, with a total of 410 soil samples collected. The program commenced with infill sampling on a 50m by 100m grid at NB-NE, with the objective of confirming and refining the shape of a strong lead anomaly that had been identified during previous exploration campaigns. Soil sampling was also completed on a 100m by 200m grid at the Niamabimbou Northern Tributary (NB-NT) and in the southern parts of the Prospect (50m by 100m infill grids at NB-SE and NB-SW) in order to identify new anomalies. Results from the soil sampling grids are anticipated in late February.
Dignali and Ofoubou Prospects
Programs of geological mapping, rock chip and soil sampling were also carried out at the Dignali and Ofoubou Prospects (Figure 3) where very limited exploration has been carried out to date.
At the Dignali Prospect a total of 72 points of observation were mapped and six mineralised outcrops sampled (assays pending). Despite lack of significant outcrop, the Dignali setting is considered favourable for lead-zinc mineralisation under cover.
A new 100m by 100m soil grid was sampled in the south-east tributeary of Dignali embayment. This 2km long narrow arm of Cretaceous sediments is located in a favourable erosive domain and is prospective for structurally controlled mineralisation.
Soil sampling at the Ofoubou prospect was carried out on a 100m by 200m grid covering the southern side of the channel. A total of 116 soil samples collected.
Results from the soil sampling grids at the Dignali and Ofoubou Prospects are anticipated in late February.
Initial Metallurgical Testwork
An initial metallurgical testwork program in 2018 produced separate, high-grade, high-recovery zinc and lead concentrates with very low deleterious / penalty elements (antimony, arsenic, bismuth and mercury impurities were all below the detection limit).
The testwork predicted relatively potential low-energy costs due to low grind times to achieve target sizing (see Treks ASX Release dated 8 November 2018). The independent testwork, undertaken by METS Engineering in Perth, Western Australia, resulted in the production of:
- Lead concentrate up to 79% Pb (overall un-optimised lead concentrate graded >70% Pb with > 90% recovery); and
- Zinc concentrate up to 58% Zn (overall zinc concentrate graded 53% Zn at 65% recovery, with the majority of the zinc losses reporting to the lead rougher concentrate. Of the zinc reporting to the zinc rougher, 90% was recovered. Further optimisation on zinc depression in the lead rougher is expected to significantly improve the overall zinc recovery
Exploration Plan
The initial exploration program is focussed on defining sufficient shallow (open-pittable), high grade zinc-lead mineralisation to justify commencement of feasibility studies.
The proposed work plan for the Kroussou Project includes:
· Conduct surface exploration programs comprising geological mapping, rock chip and soil sampling to further assess identified prospects and to generate new targets within the broader project area;
· Rank and prioritise exploration targets across the project area based on newly acquired and historical data;
· Plan for the mobilisation of a track-mounted reverse circulation (RC) rig suitable for a rapid drilling program over multiple channels;
· Mobilise drill rigs to conduct an infill and extensional drilling program at the Dikaki Prospect and initial drill testing of other priority targets;
· Create road access to new prospects in anticipation of an aggressive drill program;
· Conduct ground geophysics to refine identified prospects and generate new targets;
· Continue metallurgical test work over all prospective targets to assess recovery characteristics, concentrate quality, and variability;
· Estimation and reporting of a Mineral Resource in accordance with the JORC Code; and
· Commence with feasibility studies.
The Company will undertake the work program with a strong commitment to all aspects of sustainable development and responsible mining, with an integrated approach to economic, social, environmental, health and safety management.

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

as well as others along
various river systems on the
Kroussou license.
BRGM conducted drilling on the

historical reports and drill

Trek completed soil surveying,
mapping, rock chip sampling,
ground geophysics and two
drilling programs to confirm
historical results during
2017 and

mineralisation is similar to

On a regional scale, the Pb-Zn
mineral concentrations are
distributed at the edge of

Mineralisation is located
within the
Gamba Formation part of the NZ

during the Cretaceous as part
