The channel sediments are mineralised over very significant widths which opens up the broader potential within the deeper, much more voluminous basin to the west
-
Results confirm emergence of Trek’s Kroussou Project as a potentially world‐class zinc‐lead discovery
-
Drilling is now completed, with further assay results to be reported in the weeks ahead
Trek Metals Limited ( “Trek” or the “Company” ) (ASX:TKM) is pleased to present further highly encouraging results from the recent drilling completed at its flagship Kroussou Project in Gabon (Figure 1) (“ Kroussou ”).
These latest drill results continue to demonstrate the presence of highly significant, sulphide dominated zinc‐lead mineralisation that has been intersected at or very near to surface, and offers potentially very large scale, open pitable ore systems (Figures 2‐7).
A number of assays have been received from drilling targeted within the Dikaki Channel, which is the most advanced of the many Kroussou Project prospects, and first of several channels in which Trek expects to define JORC Resources during 2019.
Best results from latest drilling within the Dikaki Channel returned:
-
5.5m @ 1.2% Zn + Pb (DKDD018 from 15.1m – 20.6m)
-
4.2m @ 1.8% Zn + Pb (DKDD019 from 32.0m – 32.6m)
-
1.7m @ 4.6% Zn + Pb (DKDD023 from 20.2m – 21.9m)
-
7.8m @ 2.5% Zn + Pb (DKDD025 from 33.0m – 40.8m)
In addition to the results at Dikaki, Trek is pleased to confirm that diamond drilling within the Bouambo South channel, located only 4km SW of Dikaki, targeting soil anomalies and rock chips has confirmed its potential as a host to significant mineralisation (Figure 8, Table 1). The results for part of DKDD004, released in September ( 5.8m @ 6.5% Zn + Pb from 10.2m ), have now been complemented by further results from DKDD001 and 002 that provide confidence that mineralisation is widespread within the Bouambo South channel. This re‐affirms the Company’s belief that there is potential for Kroussou to host several large deposits within multiple channels contained within the project area. Assays from the remaining holes into the Bouambo South channel are expected to be received in the coming weeks.
Key to the potential of the Kroussou Project, is understanding the very large scale and the broad nature of the anomalism and mineralisation that is present in the channels along the basin margin.
These windows into the basin present, in themselves, very large tonnage targets with the volume of rock present in the broader basin to the west, offering an opportunity for the discovery of potentially super‐ giant base metal deposits.
Trek has clearly demonstrated with the limited drilling undertaken to date, that the mineralising system is in the order of several tens of kilometres long and present within vast thicknesses of the sediment pile, providing all the ingredients for a very significant orebody to have developed under the right conditions.
Further results from the remainder of the recently completed drilling programme are anticipated in the coming weeks.
TKM’s Managing Director Bradley Drabsch commented:
“The latest results continue to validate our exploration approach and signal that we are genuinely onto an ore forming system of significance that could produce numerous, very large mineralised bodies located at or very close to the surface.
Dominated by sulphide ore minerals, these deposits would potentially be very easy to mine and process and present real company‐making opportunities. We have yet to explore the broader basin to the west, which is potentially where even larger, even more significant mineralisation could be hidden under cover.”

JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
(Criteria listed in the preceding section also apply to this section.)
| 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. 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 (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30g 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. |
Trek Drilling Drill core has been cut in half using a coresaw. Sampling is being and has been conducted to industry standard with samples taken either at metre or geological boundaries as appropriate with a minimum sample length of 0.3m (some minor exceptions due to core loss in some intervals). Core has been cut to ensure that both sides approximate one another to ensure representivity of each length. Historic Drilling Due to the historic nature of the drilling results reported herein, it is not possible to comment on the quality of the sampling used to produce the results described. It is known from the historic reports that the drillcore was sawn. TKM continues to try to locate any remnant core from the drilling but as yet as been unsuccessful. It is highly likely that, due to the passage of time, the core from the BRGM work in the 1960’s and 1970’s has been lost or destroyed. Results were obtained from historic reports produced by the Bureau de Recherches Géologiques et Minières (BRGM, French Geological Survey) during the 1960’s and 1970’s. |
| 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). |
Trek Drilling Drilling is either HQ diamond (63.5mm diameter core) or NQ diamond (47.6mm diameter core) standard tube. Historic Drilling Drilling was completed using a Winkie style diamond drill rig producing drill core ofapproximately25mmdiameter. |
| 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 _ |
Trek Drilling Core recoveries are measured using industry standard methods for each run of core drilled. The use of HQ and NQ diamond core ensures the best recovery under the conditions experienced in the project area. No relationshipbetween recoveryandgrade has been established. |

| loss/gain of fine/coarse material. | Historic Drilling Due to the historic nature of the drilling results reported herein, it is not possible to comment on the recoveries achieved at the time. Only sporadic reference to recoverywas made in historic logs. |
|
| 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. |
Trek Drilling Field logging to industry standard has been conducted on the drill core in its full condition. The core will be re-logged once cut. All observations are logged in Microsoft Excel before being uploaded into the company database. This method will allow the logging to support Mineral Resource Estimations if/when required. Geological observations such as lithology, alteration, mineralisation etc are qualitative whereas recovery, RQD etc are quantitative. 100% of the drill core has been fully logged and photographed (dry and wet). 100% of the non-sampled core has been retained and stored for future reference. Historic Drilling All drill core was logged in detail, however, due to the age of the drilling and the inability to check-log the core due to its destruction, these logs can be used as a guide only and will not be suitable for use in a Mineral Resource estimation. Qualitative: Lithology, alteration, mineralisation etc. All holes for their entire length appear to have been logged, however, some logs are missing from the historic dataset). |
| 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. _ |
Trek Drilling The drill core has been cut in half using a standard petrol-powered core saw. Sampling half core is industry standard. Core has been cut to ensure that both sides approximate one another to ensure representivity of each length. The sample size collected is appropriate for this stage of exploration. Historic Drilling Due to the historic nature of the drilling results reported herein, it is not possible to comment on the method of sampling, sampling techniques and sample preparation methodology. |

Trek Drilling Samples from the first phase of drilling (Hole DKDD001 – 009) were processed in Gabon by Setpoint laboratories. Samples were: oWeighedoDriedoCrushed to 80% passing 2mmoPulverised to 80% passing 80 micronsoPackaged and sent to Intertek Genalysis in Perth for assay Samples from the second phase of drilling (all other holes) were processed in Ghana by Intertek Genalysis laboratories. Samples were: oDriedoCrushed to 2mmoPulverised to 85% passing 75 micronsoPackaged and sent to Intertek Genalysis in Perth for assay All Samples are assayed by Intertek Genalysis in Perth using a 4 acid digest (considered a total digest) with an ICP-OES or ICP-MS (element dependant) finish for a suite of ore and indicator elements Laboratory and Trek submitted QAQC samples returned results within acceptable limits to date. Historic Drilling Due to the historic nature of the drilling results reported herein, it is not possible to confirm the method of assay or analytical technique however historical reports indicate the drill samples were analysed using atomic absorption methods but the digestion method is not clear. No description of QAQC protocols are provided in the historic reports. |
| 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. |
Trek Drilling All logging observations are handwritten or entered into a field laptop using MS Excel before being uploaded into the company database. Historic Drilling Due to the historic nature of the drilling results reported herein, it is not possible to verify any of the results. TKM has drilled a number of holes in an effort to twin historic holes. This process has resulted in confirmation that the assay results published in historic reports are valid and can be used to guide modern exploration. Due, however, to numerous uncertainties, these historic results cannot be used for the estimation of mineral resources. |

| 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. |
Trek Drilling A handheld GPS was used to locate each sample. Sample locations are provided as UTM co-ordinates within Zone 32, southern hemisphere using WGS 84 datum. Easting and Northing is typically accurate to +/-10m with RL presented as nominal at this stage. Accurate topographic control is yet to be established. Historic Drilling Drillholes were located according to topography on maps produced at the time of drilling. A process is underway to attempt to accurately locate these; however, this process is incomplete at this stage. Location accuracies are approximately +/- 10m but may be less accurate in certain areas due to difficultyin locatingmapped features. |
| 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. |
Trek Drilling Samples have been collected at regular 1m intervals unless a specific geological boundary of significance is within an interval. Samples are then adjusted to reflect that boundary to a minimum length of 0.3m (some minor exceptions due to core loss in some intervals). Whilst no Mineral Resources are discussed in this announcement, logging, sampling, assaying and associated data collection is being conducted to industry standard levels for future use in Resource/Reserve calculations if/when required. Historic Drilling Drillhole collars described in historical reports are spaced at various intervals including random locations and on grids of 50m x 100m and 25m x 50m. Due to the historic nature of the drilling results reported herein, they will not be suitable for use in a Mineral Resource estimation. |
| 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. |
Trek Drilling and Historic Drilling Drillholes are vertical (one hole only has been drilled at -60o). Due to the shallow dipping nature of the known geology in the project area, this orientation is considered appropriate. |
| Sample security |
The measures taken to ensure sample security. | Trek Drilling Samples were transported from the field by company field personnel and then tothe preparatory and assayinglaboratoryviaDHL. |

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. |
TKM owns the Kroussou Project in Gabon 100%. Havilah Consolidated Resources (HCR) holds a 0.75% NSR. This royalty may be bought back from HCR by TKM for US$250,000. ASX:BAT holds a 2.5% NSR with 1% subject to buy back by TKM for US$1.5M. The Kroussou tenure is an Exploration License (G4-569) renewable each year for a further 3-year period beginning the 2ndJuly 2015. The renewal process for the second 3-year period is currently underway. The Company is not aware of any impediments relating to the licenses or area. |
| 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, 1977-1980. ASX:BAT obtained historical reports and drill logs relating to BRGM’s field program and completed cursory rock chip and mapping work in 2015 and 2016. |
| 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 – elevation above sea levelin metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception depthohole length. |
See table 1 within the document. |
| 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. 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. _ |
Trek Drilling Intervals reported using a minimum width of 1m and a minimum assay of 1.0% Zn + Pb and a maximum of 3m internal dilution |
| Relationship between mineral- isation widths and intercept lengths |
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 (eg ‘down hole length, true width not known’). |
Trek Drilling and Historic Drilling Mineralisation is understood to be within shallowly dipping horizons and therefore vertical drillholes should intersect zones at approximately right angles and approximate true widths. |
| 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. |
Refer to figures and tables in report. |
| 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. |
See table 1 within the document. |
| 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. |
