Evidence Mounting for Copper Potential at Sandover - NT
-
Additional surface sampling and field reconnaissance completed at Sandover in April 2022 confirmed further areas of surface copper oxide mineralisation
-
Historical drill holes (drilled in 1968, 1971 & 1994) reviewed at Alice Springs Core Library
-
Key geological units and processes for the formation of sediment-hosted copper established
-
Nodules of copper sulphide minerals, including bornite, identified in historical drill core providing evidence of high grade mineralisation processes
-
Encounter awarded a $100,000 grant by the Northern Territory Geological Survey (“NTGS”) to complete a gravity survey at Sandover which is scheduled to commence in the coming weeks
-
Sandover has been expanded by 2,195km[2] to increase Encounter’s portion of the Northern Arunta Pegmatite Province. The potential for lithium and other critical metals will be investigated in conjunction with copper exploration activities.
The directors of Encounter Resources Ltd (“Encounter”) are pleased to provide an update on exploration activities at the 100%-owned Sandover project in the Northern Territory.
Commenting on Sandover’s emerging copper potential, Managing Director Will Robinson said:
“Evidence of the processes that produce high grade copper mineralisation continue to mount at Sandover.
A field trip by our team in April 2022 confirmed further areas containing copper-bearing shale units. In addition, bornite nodules within a mineralised grey shale horizon were identified in both surface sampling and historical drill core at Sandover.
The shale units containing the outcropping copper at Sandover are only considered to be moderate reductants but have precipitated considerable copper which provides evidence that a highly copper charged fluid has been active at Sandover.
We have also significantly expanded our footprint over the Northern Arunta Pegmatite Province.
A detailed gravity survey is scheduled to commence in the coming weeks to inform the basin wide stratigraphic model for drill targeting. Encounter appreciates the co-funding support from the NTGS.”

CAUTIONARY STATEMENT ON VISUAL ESTIMATES OF MINERALISATION
References in this announcement to visual results are from historical diamond drilling from Sandover stored at the Alice Springs Core Library. Photos 1 & 2 provide information supporting the geological context of observations of mineral processes reported in this announcement.
Visual estimates of mineral percentages are based on preliminary visual observations of the drill core surface as presented in the core trays and may not be representative of potential mineralisation at Sandover. Visual estimates of mineral abundance are not considered to be a proxy or substitute for laboratory analyses where metal concentrations or grades are the factor of principal economic interest.
The Company does not intend to complete laboratory assays of the samples in Photos 1 and 2.
Background
Sandover is located 170km north of Alice Springs and covers a major structural corridor on the southern margin of the Georgina Basin. Access is excellent with the Stuart Highway and Ghan railway extending through the western margin of the project.
Sampling in October 2021 was conducted in four field areas located up to 6km apart (Figure 1). Each area confirmed the presence of an outcropping red-bed sandstone sequence with multiple narrow but strike extensive grey shale units containing copper oxide mineralisation (malachite). Sampling of copper mineralisation at surface returned assays up to 20.9% Cu and a suite of highly anomalous pathfinder elements (Zn, Ag, As, Bi, Mo and Pb) (refer ASX announcement 16 December 2021) .
Copper Exploration Activity
Additional surface sampling and field reconnaissance was completed in April 2022. This program confirmed additional mapped areas containing surface copper oxide mineralisation (see Figure 1, Area 5). The surface mapping also identified small bornite nodules, interpreted to be zones of increased fluid flow after replacement of anhydrite, within the grey shale unit (Photo 1).
Surface samples were also collected from various outcropping stratigraphic horizons for chemical analysis and stratigraphic correlation.
Inspection of historical drill core from Sandover in the Alice Springs core library was completed in April 2022. A number of historical drill holes (drilled in 1968, 1971 and 1994) were reviewed and confirmed key geological units and processes to enable the formation of sediment hosted copper deposits are present. Significantly, narrow zones of copper sulphide minerals, including bornite, were identified in historical drill core (Photo 2).
It is interpreted that the copper rich nodules identified at the surface represent the weathered form of the bornite nodules observed in historical drill core. This provides encouraging evidence that processes capable of forming high grade copper mineralisation are present in the basin.
Furthermore, shale units containing the outcropping copper mineralisation at Sandover are considered to be only moderate reductants yet have precipitated considerable copper. This suggests that a highly copper charged fluid has been active at the project.
Accordingly, exploration activities at Sandover are focused on identifying more reduced units within the basin. There will be a particular emphasis on where these units intersect long-lived basin forming structures which are areas with the potential to host major mineral deposits.

NTGS Funding
All available geophysical datasets have been compiled, integrated and evaluated by Encounter’s geophysical consultant Terra Resources. As a result of this exercise, 1x1km spaced gravity data has been identified as a key dataset to be collected. Encounter has been awarded a $100,000 grant to complete this gravity survey at Sandover under the Northern Territory Geological Survey Geophysics and Drilling Collaborations Program.
Sandover Lithium and Critical Minerals Potential
Sandover sits within the Northern Arunta Pegmatite Province. NTGS interpret that these pegmatites are Lithium-Caesium-Tantalum (LCT) pegmatites similar to the host pegmatites of the lithium deposits at Greenbushes in Western Australia and the Finnis deposit in the NT*. The presence of LCT type pegmatites is further supported at Sandover by two tin-tantalum occurrences in the south-east of the project area which also occur within these pegmatite mineral systems. The region’s lithium prospectivity has also been recognised by a number of other companies including Core Lithium Ltd (ASX:CXO) who hold the Anningie and Barrow Creek Lithium Projects in the district.
Sandover has been expanded by 2,195km[2] to increase the portion of the Northern Arunta Pegmatite Province controlled by Encounter. The new tenure contains additional mapped pegmatites with lithium potential (Figure 4). The potential for lithium and other critical metals will be investigated in conjunction with copper exploration activities.
Next Steps
The development of a basin wide stratigraphic model is in progress and a NTGS co-funded gravity survey is scheduled to commence in June/July 2022.
Data compilation of historical tin-tantalum exploration will assess the potential for LCT (Lithium-CesiumTantalum) pegmatites at Sandover.

SECTION 1 SAMPLING TECHNIQUES AND DATA
| SECTION 1 SAMPLING 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. Areas 5-7 at the Sandover project were sampled by Encounter staff by surface rock chips. Rock chip samples were taken of outcropping and float rocks including copper bearing mineralisation contained within grey shale units. Rock chips are random, subject to bias and often unrepresentative for the typical widths required for economic consideration. This announcement also includes initial visual observations from historical diamond drill core inspected from Sandover stored at the Alice Springs Core Library. Photos 1 & 2 provide information supporting the geological context of observations of mineral processes reported in this announcement. Visual estimates of mineral percentages are based on preliminary visual observations of the drill core surface as presented in the core trays and may not be representative. The Company does not intend to complete laboratory assays of the samples in Photos 1 and 2. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used Sample locations were recorded by handheld GPS, which has an estimated accuracy of +/- 5m. |
|
| 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 Rock chip samples were sent to Bureau Veritas Minerals Pty Ltd Laboratories in Perth, where they will be dried, crushed, pulverised and split to produce a sub – sample for ICP (OES) (MS) 4 Mixed Acid Digest. |
|
| 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). No drilling was undertaken by Encounter. Historical drill core inspected from Sandover region was inspected at the Alice Springs Core Library. Diamond core varied between AQ and BQ diameters. Core was not oriented |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed No drilling undertaken by Encounter. Historical drill core from Sandover region was inspected at the Alice Springs Core Library. Core loss did not appear to be a major issue in the historic core sample |
| Measures taken to maximise sample recovery and ensure representative nature of the samples No drilling was undertaken by Encounter. Historical drill core from the Sandover region was inspected at the Alice Springs Core Library. |
|
| 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. Rock chips are random, subject to bias and often unrepresentative for the typical widths required for economic consideration. |

|---|---|
| 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. A geological description was recorded and photograph taken of each surface sample prior to submission to the lab for analysis. Historical core was viewed at the Alice Springs core facility and photographed in detail to support exploration targeting at the project. As this is early phase exploration no detailed studies are warranted. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Geological logging is qualitative in nature and records interpreted lithology, alteration, mineralisation, structure, veining and other features of the samples. |
|
| The total length and percentage of the relevant intersections logged All surface samples have been logged by Encounter geologists. Core has also been inspected and photographed by Encounter geologists. |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. Historical drill core from the Sandover region was inspected at the Alice Springs Core Library. No additional sampling was completed by Encounter staff. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. No non-core drilling |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. For rock chip samples, sample preparation is being completed at Bureau Veritas Minerals Pty Ltd Laboratories in Perth. Samples will be dried, crushed, pulverised (90% passing at a ≤75µM size fraction) and split into a sub – sample for ICP (OES) (MS) 4 Mixed Acid Digest. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. Field QC procedures involve the use of commercial certified reference materials (CRMs) and in house blanks. The insertion rate of these will be at an average of 1:33. |
|
| 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. No duplicate samples were taken. Rock chips are random, subject to bias and often unrepresentative for the typical widths required for economic consideration. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. The rock chip sample sizes are considered appropriate to give an indication of the outcropping geological units at Sandover. |
|
| 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 rock chip samples will be analysed by ICP using a 4 mixed acid digest including Hydrofluoric, Nitric, Hydrochloric and Perchloric Acids. This extended digest approaches a total digest for many elements however some refractory minerals are not completely attacked. Assays will be determined by Inductively Coupled Plasma (ICP) Optical Emission Spectrometry (OES)(Al, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, S, Sc, Ti, V, Zn) and ICP – Mass Spectrometry(MS) (Ag, As, Bi, Cd, Co, Ga, Hf, In, La, Mo, Nb, Pb, Rb, Sb, Sn, Sr, Ta, Te, Th, Tl, U, W, Y, Zr) plus additional elements includingBe, Cd, Ce, Cs, Dy, Er, Gd, Ho, In, Lu, Nd, Pr, Re, Sm, Tb, Tm, Yb No sampling of the drill core has been completed by Encounter staff to date |

Historical drill hole collar locations are collated from exploration reports into the Northern Territory open file database COREDAT |
| Specification of the grid system used. The grid system used is MGA_GDA94, zone 53. |
|
| Quality and adequacy of topographic control. Estimated RLs were assigned to be corrected at a later stage using a more detailed DTM. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Rock chips at the Sandover prospect have been collected in seven areas, over 15km apart. |
| 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. Mineralisation has not yet demonstrated to be sufficient in both geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications to be applied. |
|
| Whether sample compositing has been applied. No sample compositing has been applied |
|
| 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. No sampling of the drill core has been completed to date by Encounter Resources. Historic drilling has intersected lithologies at approximately true width |
| 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. No sampling of the drill core has been completed to date by Encounter Resources Historical drilling has intersected lithologies at approximately true width |
|
| Sample security | The measures taken to ensure sample security. The chain of custody is managed by Encounter. Samples were delivered by Encounter personnel to the assay laboratory. |

| 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 sampling of the drill core has been completed by Encounter staff to date |
| 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 sampling of the drill core has been completed by Encounter staff to date |
|
| 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. Refer to body of this announcement |
|
| 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. All meaningful and material information has been included in the body of the text. |
|
| 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. |
