ASX Announcement 19 August 2020
First Mover Camp Scale Copper Projects in the NT
-
Six new project areas covering 14,800km[2] pegged in the Northern Territory based on their potential to contain large, sedimentary-hosted and IOCG style copper deposits
-
The areas lie in a highly prospective but vastly underexplored region under shallow cover located between the major copper-gold producing districts of Mt Isa and Tennant Creek
-
Systematic investigation of rock chips generated from water bore sampling at the Jessica project has identified the existence of near surface copper oxide (malachite) mineralisation (Photo 1)
-
Standout 50km-long copper in groundwater anomaly which is supported by surface geochemical sampling at the Elliott project (Figure 1)
-
Projects were first identified by analysing new datasets generated by Geoscience Australia, as part of the Federal Government’s Exploring for the Future Program
-
Data compilation is continuing across all project areas and the first aircore drill program at Jessica will begin once drilling approvals have been received
-
Consistent with our project generation business model Encounter will consider opportunities to advance the projects through the next phase alone or in conjunction with an earn-in partner

Commenting on the new copper projects, Encounter Managing Director Will Robinson said:
“Copper sourced from sedimentary-hosted deposits is one of the largest sources of copper metal in the world today. The potential for sedimentary-hosted copper deposits to be found under thin cover in the Northern Territory is being opened up through the interrogation of new government datasets. Encounter moved early and aggressively to secure a series of camp scale, first mover opportunities in this new frontier. Early exploration has yielded exciting results which we will now seek to build on.”

The directors of Encounter Resources Ltd (“Encounter”) are pleased to provide an update on project generation activities in the Northern Territory.
Background
New datasets provided by Geoscience Australia (“GA”), as part of the Federal Government’s Exploring for the Future Program, resulted in the application for new exploration licences comprising the Elliott and Jessica copper projects in the Northern Territory.
Elliott Copper Project (“Elliott”) – EL32156, EL32157, EL32158, EL32159, ELA32226, ELA32329 and ELA32437
Elliott was the first project secured by Encounter in the Northern Territory. The project comprises seven tenements covering more than 4,500km[2] . Four of the tenements covering over 3,000km[2] were granted in March 2020. The project is located on the Stuart Highway which runs along the western margin of the project.
Elliott is located at a major structural intersection on the southwestern margin of the Beetaloo Basin targeting sedimentary hosted copper. The Beetaloo Basin is part of the Greater McArthur Superbasin that hosts the giant sediment hosted base metal deposit at McArthur River. The basin contains thick, petroleum bearing, reduced sediments which is an ideal trap sequence and structural setting for major sediment hosted base metal deposits.
Historical exploration within adjacent properties has confirmed the presence of red beds and evaporites within the sedimentary sequence which is an important ingredient in sedimentary copper deposit models. The project encompasses key conceptual criteria for the formation of sedimentary copper and the target sequence is undercover and untested.
New GA datasets released in 2019 and 2020 have supported the conceptual and structural targeting model at Elliott. The standout, copper in groundwater anomaly (order of magnitude above background) in the extensive GA sampling program is located at Elliott. This copper in groundwater anomaly is supported by a copper soil anomaly also collected by GA.
Elliott represents a compelling first mover copper opportunity in a high quality juristiction. Data compilation and a validation program is progressing and is scheduled to be completed in 2020 to allow for on ground exploration to commence in 2021.
Jessica Copper Project (“Jessica”) – EL32273, ELA32317, ELA32338, ELA32339, ELA32386, ELA32387 and ELA32388
Jessica was the second project secured by Encounter in the Northern Territory. Jessica covers approximately 5,500km[2] along key structural corridors east of Tennant Creek and is prospective for sedimentary-hosted copper and IOCG style deposits. Access to the project is via the sealed Tablelands Highway that traverses the western side of Jessica.
Systematic assessment of drill chips from water bores at Jessica has been conducted by Encounter and previous explorer Natural Resources Australia (“NRE”) utilising handheld XRF machines. Areas of copper anomalism were selected by NRE for chemical analysis. Assay results from the interval 0-3m sample in RN28419 (No. 39 water bore) returned 1.5% copper. Visual inspection of this interval by Encounter geologists confirmed the presence of abundant copper carbonate in the form of malachite (Photo 1).

The first tenement at Jessica, which covers the RN28419 (No. 39 water bore), was granted in August 2020. Preparations have commenced for an aircore drill program to confirm the copper mineralisation identified in the water bore cuttings and determine the lateral extent of the near surface copper mineralisation. This program is scheduled for October 2020, pending approvals.

Sandover Copper Project (“Sandover”) – ELA32374 and ELA32421
Sandover covers an intersection of major structural corridors on the southern margin of the Georgina basin, 200km north of Alice Springs. Historical exploration at Sandover has mapped copper oxides at surface in a stratiform position extending over 20km of strike. Exploration will focus on the down dip continuation of this horizon and identifying where this mineralised horizon extends under cover.
Carrara Copper/Zinc Project (“Carrara”) – ELA32476 and ELA32477
Carrara was secured following the release of the South Nicholson Seismic Survey, a foundational dataset acquired as part of the GA Exploring for the Future Program. A key finding of this study is the correlation of prospective stratigraphic units from the Isa Super basin into the Carrara Sub-basin that extended the Mount Isa Province to the west. The Carrara project is located at an interpreted structural offset of the western margin of the Carrara Sub-basin where the prospective Isa Super basin has been modelled closer to surface.
Brunchilly Copper/Zinc Project (“Brunchilly”) – ELA32478
Brunchilly contains a zinc in groundwater anomaly (top 1% of results) in the GA sampling program and is located on a major north-east trending regional structure north of Tennant Creek. This anomalous sample is supported by elevated anomalism in pathfinder elements that are considered prospective for sedimentary-hosted base metals deposits.
Playford Copper Project (“Playford”) – ELA32493
Playford is located in a region of copper regolith anomalism identified through handheld XRF analysis of water bore drill chips. The bore is located on the margin of an interpreted felsic intrusion identified in a seismic survey completed by GA in the Exploring for the Future Program.
Conclusion
Encounter has secured a large and highly prospective project portfolio in the Northern Territory focused on the discovery of base metal deposits under shallow cover. The new datasets provided by GA as part of the Exploring for the Future Program provide crucial new data to open up and facilitate exploration in this covered, highly prospective and underexplored region of Australia (Photo 2).
The compilation, interpretation and modeling of the data packages at Elliott will continue through to the end of 2020. At Jessica, preparations have commenced, and an aircore rig has been tentatively booked for a drill program to be completed in October 2020, pending approvals. Data compilation and validation will continue at Jessica with remaining tenements expected to the granted in early 2021.
Encounter will continue to progress access agreements and complete data validation at the Brunchilly, Carrara, Playford and Sandover projects in the lead up to the grant of these tenements which is expected early in 2021.
Consistent with our project generation business model Encounter will consider opportunities to advance this project through the next phase alone or in conjunction with an earn-in partner.

SECTION 1 SAMPLING TECHNIQUES AND DATA
| SECTION 1SAMPLING TECHNIQUES AND DATA | |
|---|---|
| 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 sounds, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. A small sample of drill chips from each 3m interval was collected from RN28419 and stored by the Northern Territory Geological Survey at the Darwin Core Facility. The single hole RN28419 completed at the #39 water bore was drilled as a replacement to the original failed bore. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used Drill hole collar locations were recorded by handheld GPS and are considered to be an approximation. |
|
| 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 Rotary air blast (RAB) drilling was used to collect drill chips at 3m intervals down hole and small (~100gm) sub samples from these intervals were stored by the NTGS. A previous explorer, Natural Resources Australia (“NRE”) used handheld XRF units to identify intervals of anomalous geochemistry. The interval from 0-3m in RN28419 was then selected by NRE for chemical analysis. Material from this interval was sent to ALS laboratories for Aqua Regia ICP-AES analysis. Encounter geologists have inspected the RN28419 sample stored at the Darwin Core Facility and have confirmed the presence of copper carbonate mineralization through visual inspection and use of a handheld XRF |

| 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). Results reported in this announcement from RN28419 refer to samples from rotary air blast drilling. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed Historical documents on which this report is based does not detail this information. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples Historical documents on which this report is based does not detail this information. |
|
| 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. Historical documents on which this report is based does not detail this information. |

| For all sample types, the nature, quality and appropriateness of the sample preparation technique. Sample preparation was completed at ALS Laboratories. Samples were dried, crushed, pulverised (90% passing at a ≤75µM size fraction) and split into a sub – sample that was analysed using ICP – AES analysis. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. The sub sample collected from the 3m sample interval is small at ~100gms. No information is available to determine how representative the sub sample is of the original interval. |
|
| 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. Historical documents on which this report is based does not detail this information. |

|
| 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 sample(s) for ICP analysis have been digested using Aqua Regia methodology. This digest methodology produces variable digestion of various elements due to the variable refractory nature of minerals. Samples were analyzed for 35 elements by ICP – AES method (Cu, Fe, Ga, Hg, K, La, Mg, Mn, Ni, P, S, Sc, Ti, Zn, Ag, Al, As, Ba, B, Be, Bi, Ca, Cd, Cr, Co, Mo, Na, Pb, Sb, Sr, Tl, U, V, W and Au). |
| 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. Handheld XRF device used was a Thermo Niton XL3t 500 although these results are not reported and were only used to determine which intervals were sent for wet chemistry analysis. |
|
| 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. Historical documents on which this report is based does not detail this information. |

| Data aggregation methods Relationship between mineralisation widths and intercept lengths Diagrams Balanced Reporting Other substantive exploration data Further Work |
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. No weighting or cut-offs have been applied to the results |
| Where aggregated 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. No aggregation of results has been applied to the results |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. No metal equivalents have been reported in this announcement. |
|
| 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. 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’). The geometry of the mineralisation is not yet known due to insufficient drilling in the targeted area. |
|
| 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 plane view of drill hole collar locations and appropriate sectional views. The reported result is a single sample from a single hole and therefore plans or sections are considered inappropriate at this time. |
|
| Where comprehensive reporting of all Exploration Results is not practical, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. The reported result is a single sample from a single hole with no other wet chemical analysis completed on the samples from this hole. |
|
| Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observation; 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 has been included in the body of the text. No metallurgical or mineralogical assessments have been completed. |

| The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large – scale step – out 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. A program of shallow aircore drilling is being designed to confirm the copper oxide mineralization seen on RN28419 and to test for the extent of this mineralization. |
