Putting the Explore back into Modern Exploration
DiscovEx Resources Limited (ASX: DCX) is pleased to announce the results from the compilation of recently completed soil sampling results at Edjudina. Together with historic soil data, several new targets have been highlighted within both the Hornet Prospect area and the broader project area. Further work on these new areas, including additional surface sampling to better define the anomalies, will culminate in the drill testing of the highest priority targets later in the year.
DCX is also pleased to advise that aircore drilling at the Hornet West prospect is set to re-commence within the next two weeks. Recently completed drilling has provided the Company with a highly significant, consistent, highgrade gold in basement trend over greater than 200m, open in all directions. The most important results from that drilling included:
-
2m @ 3.0 g/t Au from 50-52m EOH (including 1m @ 5.3 g/t Au) in HOAC012
-
• 7m @ 1.4 g/t Au from 40-47m EOH (including 3m @ 2.8 g/t Au) in HOAC032; and • 1m @ 3.4 g/t Au from 54-55m in HOAC026
Visible gold, providing confidence that the mineralisation is in-situ and potentially amenable to conventional processing (yet to be confirmed with cyanide leach assay testing) was panned from the two intervals in holes HOAC012 and HOAC032.
The DiscovEx team plans to continue aircore drilling at Hornet within the next two weeks. A programme of approximately 2,500m will be completed with subsequent RC drill testing to follow.
DiscovEx has also been fortunate enough to win a WA Government Exploration Incentive Scheme (EIS) co-funded drilling grant to the value of up to $80,000 to assist with the cost of diamond drill testing at Hornet. DCX plans to complete this work later in the year once final targeting has been completed.
EDJUDINA GOLD PROJECT – OVERVIEW
The Edjudina Project is situated within the southern portion of the Laverton District, about 700km north-east of Perth. The area hosts numerous major gold deposits, including Anglogold Ashanti’s Sunrise Dam (> 12 Moz Au), Saracen Mineral Holdings’ Carosue Dam (>2 Moz Au) and Matsa Resources’ Red October project (>0.5 Moz Au).
The Edjudina project covers a strike extent of over 50km within the Linden Terrain, east of the Pinjin Fault, over a north-northwest trending sequence of prospective greenstone, gneisses and granites and is immediately along strike from Matsa Resources’ Fortitude gold project (>385,000oz Au), which it continues to actively explore and expand.
Previous work on the Edjudina tenure, mostly during the 1980’s and 1990’s, included soil sampling, geophysics (both airborne and ground-based), air core (AC) drilling and minimal reverse circulation (RC) drilling. Several goldin-soil anomalies were identified during previous exploration programs, in particular at two prospect locations, Hornet and Phantom. Both areas of soil anomalism were the subject of shallow AC drilling to blade refusal. Much of this exploration effort was undertaken at a time when the gold price was less than US$300/oz and therefore the hurdles to mining were much higher than today, with gold prices currently around US$1,700.
GOLD IN SOIL ANOMALIES AT HORNET
At least three generations of soil sampling have been conducted at various spacing on a number of regions within the broader Edjudina Project tenure. Much of this sampling is considered by DCX to have been largely ineffective due to the sample media chosen for sampling. DCX considers that any samples that are coarser than the 175 micron fraction (-80 mesh) are too coarse to provide an adequate signal to noise ratio to be effective at discriminating anomalies from background. Much of the sampling around the Hornet prospect, completed in the late 1990’s, was the 2mm fraction and therefore largely ineffective. Recent sampling by DCX has highlighted this lack of anomaly discrimination at Hornet and provided numerous opportunities for further expansion, both at Hornet and more regionally.
Figure 1 below, provides a compiled representation of the surface geochemical footprint at Hornet and highlights numerous target areas that have been undrilled or drilled at a spacing that renders them effectively untested. The contouring is based upon data normalisation using percentiles. Each individual dataset, including top of hole drill assay data, was normalised to each individual dataset by dividing the data into percentiles for Au.
Several large consistent trends have been identified and will be infilled and further defined prior to subsequent drill testing.

REGIONAL GOLD TARGETS AND ADDITIONAL TENURE
An ongoing review of regional datasets, comprising drilling, geology, surface geochemistry and geophysics, has allowed the DCX team to define numerous additional targets along the length of the Edjudina Project tenure. As indicated above, much of the previous surface sampling is considered to have been largely ineffective. Some areas, such as the Tiger Prospect, have what are considered, in context, significant soil anomalies that require follow-up. Other areas of particular structural interest due to their potential to be environments where destressing and subsequent dilation could have occurred, also require investigation including surface sampling.
This work will begin together with the upcoming drilling programme and continue into the latter part of this year. The data compilation and target generation exercise will be ongoing.

| 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. |
_DCX aircore drilling:_2kg - 3kg samples collected and laid out on 1m intervals. Samples taken via a scoop on 4m composite intervals. Cyclone/sampling equipment cleaned regularly during drilling Mineralisation determined qualitatively through rock type, sulphide and quartz content and intensity of alteration. Mineralisation determined quantitatively via assay (aqua-regia digest followed by ICP-MS for gold and four-acid digest for multi-element data). Single metre assaying was completed using a 50g fire assay. Samples pulverized to 75 μm _Historical Drilling:_No recorded exploration was undertaken on the tenements before 1989. From the late 1980’s a number of exploration companies held the ground including Aberfoyle Resources Ltd, Barranco Resources, Arimco Mining, Midas Resources Ltd, Gryphon Minerals Ltd and Omni Projects Pty Ltd. Works undertaken over the project area involved: • 1km spaced soil sampling by Aberfoyle (1989) • Infill soil sampling by Arimco Mining (1998) • Vertical AC drilling by Arimco (1998) • Airborne Magnetics survey by Arimco. (1998) AC drilling was sampled on a 4m composite basis with follow up 1m splits taken post drilling from composites that returned assays >0.1g/t Au. Downhole samples were analysed for gold and multi-element determinations via Aqua Regia digest and carbon rod finish. End of hole samples were assayed for Ag, As, Bi, Co, Cr, Cu, Fe, Mo, Mn, Ni, Sb, Pb, V and Zn Aqua Regia digest and carbon rod finish. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
_DCX aircore Drilling:_The sample from the cyclone was collected in buckets and dumped into neat piles on the ground. A scoop was used to sample individual piles for the 4m composite. Care was taken to sample to industry standards. _Historical Drilling:_No information exists on sample procedures other than the use of 4m composites being 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 1m samples from which 3kg 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. |

| 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 intervals reported were taken above 0.1g/t Au with a maximum 2m of internal dilution |
|
| 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 high grades in the exploration results have not been cut. Weighted averaging has been used when calculating intervals of differing sample lengths. |
||
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalent values are used for reporting exploration results. |
||
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
No metal equivalent values are used for reporting exploration results. |
|
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
The geometry of the mineralisation is interpreted as striking north/south, however there is no information to suggest a dip of the mineralisation and is therefore not known at this stage. |
||
| 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’). |
The geometry of the mineralisation is interpreted as striking north/south, however there is no information to suggest a dip of the mineralisation and is therefore not known at this stage. |
||
| 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 and 2 within this Announcement. | |
| 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. |
Maximum Au plots can be shown in Figures 1 and 2 and include all available drill information. |
|
| 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. |
The announcement was compiled through the use of publicly available data including aeromagnetics and drill information. |
|
| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large- scale step-out drilling). |
Additional exploration activities are planned to take place in 2020, inclusive of soil sampling, ac drilling and RC drilling. |
|
| Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
