FURTHER POSITIVE RC DRILLING RESULTS FROM THE SPLIT ROCKS GOLD PROJECT
- Further assay results from phase one of the reverse circulation (RC) drill campaign at the Dulcie Laterite Pit target validate the concept of a broad scale gold mineralised shear zone target.
==> picture [6 x 5] intentionally omitted <==
- The Company previously reported initial 4m composite assay results for the first 18 RC holes of the drill program (ZDRC026 to ZDRC043) on the 17[th] Dec 2020, from a total of 27 RC holes completed on 120m spaced sections. Drilling testing the upper portion of the drill target returned gold mineralisation in every hole, except one. Notable results previously reported include:

The large-scale gold bearing bedrock shear zone extends over 2km in strike and remains open down dip (at 30[0] ) with a thickness ranging from 4 to 40m (refer to Figures 3 - 5). The depth extent is yet to be fully defined.
-
Gold zones appear to also be locally stacked and open to the east, as well as down-dip to the west, requiring a second phase of RC drilling – this will commence early this year.

These RC results compliment those previously reported from aircore drilling on the 2-Dec-20. These results included:
-
14m @ 3.5 g/t Au
-
4m @ 2.9 g/t Au
-
4m @ 1.5 g/t Au
-

-
20m @ 0.7 g/t Au (eoh)
-
12m @ 1.2 g/t Au
==> picture [5 x 6] intentionally omitted <==
- Remaining 1m resamples will be submitted to the laboratory shortly. Follow-up drilling is anticipated to recommence upon receipt of all assay results and a refined interpretation of current available data. On ground activity including drilling is anticipated in early February.
==> picture [5 x 5] intentionally omitted <==
- The Dulcie Laterite Pit is one of 3 high priority targets to being evaluated first at Split Rocks, the other two are Dulcie North with intersections of 32m @ 9.4 g/t Au, incl 9m @ 31.4 g/t Au and Dulcie Far North with an intersection of 5m @ 5.6 g/t Au. Permitting for follow-up drilling of these two areas is in progress.
==> picture [5 x 5] intentionally omitted <==
- A further 8 of the originally 18 defined gold targets have yet to have first pass drill testing. This work will proceed in early 2021.
Commenting on the results announced Chairman Peter Bird said ” We have now validated the first of multiple targets in the Dulcie area with further drilling planned at Dulcie North and Dulcie Far North. The Dulcie area is the current focus for the Company, however another 8 targets are sited within 18km of prospective strike. The next stage at Dulcie is to try and identify some higher-grade zones and to consider some great depth extensions. This activity will follow immediately after we have completed our refined interpretation of the dataset we now have. The objective here is to define a broad scale open pit type resource. The current year is going to be very interesting at Split Rocks especially once we get the permits to drill Dulcie North and Dulcie Far North”

Split Rocks Project Background on Gold Potential
Zenith’s Split Rocks project is located within the Southern Cross region in the Forrestania greenstone belt, approximately halfway between Perth and Kalgoorlie. Several very large current and previously operated gold mines located north and south along strike from Zenith’s project area attest to the regional gold endowment of this area.
A major targeting exercise by the Company’s geological team initially identified 12 high-quality gold drill targets, subsequently expanded to 18 targets in the north eastern sector of the Company’s 100% owned Split Rocks project (Refer to ZNC ASX Release 2 September 2020).
Drilling to date has tested 10 targets with outstanding first pass results returned at:
-
Dulcie North: 32m @ 9.4 g/t Au, incl 9m @ 31.4 g/t Au with the highest individual 1m sample returning 199.2 g/t Au.
-
Dulcie Laterite Pit:
-
§ 2m @ 14.5 g/t Au, incl. 1m @ 20.8 g/t Au,
-
§ 18m @ 2.0 g/t Au (EOH) incl. 1m @ 23.7 g/t Au
-
§ 14m @ 3.5 g/t Au &
-
§ 2m @ 4.7 g/t Au incl. 1m @ 8.3 g/t Au
-
Estrela Prospect: 2m @ 9.8 g/t Au (open to north & south)
-
Dulcie Far North: 5m @ 5.6 g/t Au incl. 4m @ 6.8 g/t Au
Phase 2 follow-up drilling at Estrela provided sufficient encouragement to continue to test the identified structural target further along strike to the north with new results including 2m @ 0.4 g/t Au and 1m @ 0.6 g/t Au along strike from 2m @ 9.8 g/t Au and 3m @ 2.6 g/t Au. The mineralised structure at Estrela appears to be present over at least 200 metres of strike but is disrupted by numerous unmineralized pegmatites.
A further 8 of the 18 targets generated by Zenith extending over 18km of strike are yet to have first pass drill testing. Given recent positive ASX announcements, first pass testing of these additional targets will now be deferred whilst the Company concentrates its efforts on following up the significant near surface gold results at the 3 Dulcie targets, Dulcie Laterite Pit, Dulcie North & Dulcie Far North.
RC drilling at the Dulcie Laterite Pit is the subject of this ASX release, whilst permitting is now anticipated to be completed in January for a major follow-up drill campaign at Dulcie North and Dulcie Far North prospects.

Note: Zenith has gold rights below 6m from surface only. Some 4m composite results extend through the zone 4m – 8m depth interval. High-grade intersections are length weighted average grades with minimum cut -off grade of 1.0g/t Au and no internal dilution, whilst lower grade intersections are length weighted average grades with minimum cut-off grade of 0.4g/t Au and maximum internal dilution of 4m. 4m composites are based on riffle split samples, 1m resamples are all cone split.

Section 1 Sampling Techniques and
Data
(Criteria in this section apply to all succeeding sections.)
| Criteria JORC Code explanation Commentary |
Criteria JORC Code explanation Commentary |
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. |
1m assay results received for 18 reverse circulation drill holes. 4m composite assays received for the last 9 RC holes. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Two 1m drill samples were collected via a cyclone cone splitter. One set of samples was split through riffle splitter to obtain 4m composites. Selected 1m intervals were collected from the other set of 1m samples and assayed |
|
| 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. |
Reverse circulation drilling was used to obtain 1 m to 4m samples from which ~2kg was pulverised to produce a 50 g charge for fire assay |
|
| 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.). _ |
Reverse circulation |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
Drill chips were sieved and logged by a qualified geologist on site, data recorded in field on a laptop and then entered into a database |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
Drilling produced generally dry samples with excellent recoveries, all 1m samples were cone split on site with a subsequent 4m composite sample generated using a riffle splitter to ensure a representative sample was collected for assay |
|
| 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 indications of sample bias based on results to date |
| 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. |
Drill chips were sieved and logged by a qualified geologist on site. No reporting of resources |
|---|---|---|
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. |
Drill chips logging is qualitative. Representative chip samples collected and stored in 20 compartment plastic chip trays |
|
| The total length and percentage of the relevant intersections logged. |
All intervals logged and sampled | |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
No core |
| If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. |
4m composite samples were riffle split | |
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
Samples were analysed at Nagrom Laboratories in Perth, the samples were crushed, pulverised and assayed by gold using fire assay |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. |
~2kg of drill sample was crushed and pulverised and a sub-sample was taken in the laboratory and analysed. |
|
| Sub-sampling techniques and sample preparation - continued |
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. |
Field duplicates were collected during sampling by riffle splitting selected 1m samples. |
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
Each sample was ~2kg in weight which is appropriate to test for the grain size of material |
|
| 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. |
The samples were crushed and assayed for gold using fire assay which is considered a near total assay technique |
| 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. |
No geophysical tools used in this drilling program | |
| 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. |
Certified reference material, blanks and duplicates samples were included in each sample batch and appropriate levels of precision and accuracy were confirmed in QA/QC review |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
Company personnel have observed the assayed samples |
| The use of twinned holes. | No twinning |

||
|---|---|---|---|
| Discuss any adjustment to assay data. | No adjustments were made. | ||
| 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. |
Sample location is based on GPS coordinates +/-5m accuracy |
|
| Specification of the grid system used. | The grid system used to compile data was MGA94 Zone50 |
||

| Data spacing and distribution |
Data spacing for reporting of Exploration Results. |
Drill holes shown in Figures 2 to 5 and Tables 1 & 2 | |
| 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. |
The data alone will not be used to estimate mineral resource or ore reserve |
||
| Whether sample compositing has been applied. |
Drilling produced generally dry samples with excellent recoveries, all 1m samples were cone split on site with a subsequent 4m composite sample generated using a riffle splitter to ensure a representative sample was collected for assay |
||
| 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. |
The intersections in all drill holes are interpreted to be close to true widths |
|
| 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. |
As above | ||
| Sample security | The measures taken to ensure sample security. |
Samples were kept in numbered and secured bags until delivered to the laboratory |
|
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code explanation Commentary |
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. |
Zenith announced on the 21stMarch 2019 that it has a 2- year option to explore for bedrock gold (any gold 6 metres below surface) and lithium mineralisation on tenements covering the operating Dulcie Heap Leach Gold Project (DHLGO) in exchange for surface laterite gold rights on Zenith’s adjoining exploration licence E77/2388. Zenith may at its sole election exercise the option through the payment of a 2% NSR royalty payable on any future bedrock gold production from the DHLGO project area. The project is located predominantly in vacant crown land. |
| 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. |
Tenements are mining leases and prospecting leases, current heap leach operation is active, no known impediments to obtain a licence to operate. |
|
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
Refer to ASX release 21stMarch 2019. |
| Geology | Deposit type, geological setting and style of mineralisation. |
Archean mesothermal lode gold mineralisation hosted within banded iron formation (BIF) and mafic rock types. |
| 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: |
Refer to Figures 1 - 5 and Tables 1 & 2and descriptions in body of text of this ASX release and to Figures 1,2 & 3 and Table 1 and descriptions in body of text of ZNC ASX Release 21 Oct 2019 |
| o easting and northing of the drill hole collar | ||
| o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar |
||
| o dip and azimuth of the hole | ||
| o down hole length and interception depth | ||
| o 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. |
||
| 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. |
High-grade intersections are length weighted average grades with minimum cut -off grade of 1.0g/t Au and no internal dilution, whilst lower grade intersections are length weighted average grades with minimum cut-off grade of 0.4g/t Au and maximum internal dilution of 4m. |
| 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. |
As above and included in Tables | |
| Data aggregation methods - continued |
The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalents used. |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
All Zenith drilling is angled -60 degrees east and based on current interpretation is thought to be representing true width thickness of the flat lying supergene or gentle west dipping gold mineralised zones however further drilling is required to confirm this interpretation. |
|---|---|---|
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
As above | |
| 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’). |
Mineralised intervals reported are down-hole lengths but are believed to be close to true thickness |
|
| 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 1 - 5 and Table 1 and 2 in body of text of this ASX release and to Figures 1,2 & 3 and Table 1 and descriptions in body of text of ZNC ASX Release 21 Oct 2019 and those in ZNC ASX Release 5 Aug 2020 & 2 Sep 2020. |
| 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. |
Refer to Figures 1 - 5 and Table 1 and 2 in body of text of this ASX release. |
| 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. |
No other meaningful or material exploration data to be reported at this stage. |
| The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). |
Follow-up drilling planned. |
|
| Further work | Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Refer to figures in body of this report. |
