Potential to introduce a suitable joint venture partner for the Lamil Prospects in the future, consistent with Encounter’s project generator model
The directors of Encounter Resources Ltd (“Encounter / the Company”) are pleased to provide an update on generative activities in the Paterson Province.
In light of the insights gained from the recent exploration success at Rio Tinto Ltd’s (ASX:RIO) Winu copper-gold discovery (“Winu”), a regional structural review of Encounter’s Paterson Province tenure was completed as part of ongoing target generation activities.
This review has identified a series of discrete magnetic anomalies with known copper-gold mineralisation in the southern area of the Telfer West Project (“Telfer West”) on a major regional gravity-lineament. The setting is similar to that at Winu and is considered prospective to host intrusive related copper-gold deposits and will now be progressed by Encounter in conjunction with other activities.
Winu is located adjacent to the margin of the Waukarlycarly rift basin which is highlighted by a regionalscale, north-west trending gravity lineament. The gravity lineament marks the location of a significant structure and deformation zone that would have acted as a major pathway for ore forming fluids during the formation of the Proterozoic aged deposits. This gravity lineament cross-cuts the north-northwest trend of the Paterson Basin and also has a spatial relationship to Greatland Gold plc’s Havieron prospect on the east margin of the Paterson (Figure 1).
A second parallel, north-west trending gravity lineament is located ~40km south west along the margin of the Waukarlycarly rift basin. Encounter’s Lamil copper-gold prospects are adjacent to this major gravity structure. Shallow drilling in the 1980s by Newmont intersected thick zones of strong coppergold anomalism (Figure 2) which may be significant given the learnings from Winu.

Lamil Copper-Gold Prospects at Telfer West (E45/4613, 100% Encounter)
Telfer West covers an area of ~61km[2 ] and is located 25km northwest of the major gold-copper mine at Telfer, owned by Newcrest Mining Ltd (ASX:NCM) and 40km north of Encounter’s Yeneena CopperCobalt Project in the Paterson Province. Yeneena is subject to an Earn-In Option as part of an exploration partnership with Independence Group NL (ASX:IGO) (refer to ASX announcement dated 12 November 2018).
Telfer West contains the Lamil prospects where historical gold exploration, in the vicinity of a series of magnetic anomalies, was conducted by Newmont from 1983-1993. There was no exploration between that phase of exploration and the commencement of gold exploration activities by Encounter in late 2016.

Figure 2 – Detailed aeromagnetics over regional gravity image showing the location of magnetic anomalies on the margin of the Waukarlycarly rift basin
Newmont’s limited shallow drilling specifically targeted a series of magnetic features and intersected strong copper anomalism, associated with gold anomalism, at the Lamil prospects (Figures 3 & 4):
Lamil 1:
-
58m @ 922ppm Cu from 32m to end of hole (LSR87-31)
-
33m @ 1004ppm Cu and 0.45g/t Au from 96.6m (LSPC1) including:
-
5.5m @ 0.38% Cu & 1.2 g/t Au and from 124.7m
-
Broad zones of copper-gold anomalism (LHS88-4) with narrow intersections up to 1.2% Cu and 1.9 g/t Au (thick areas of missing assays to be re-analysed (see Figure 4))
Lamil 3:
-
62m @ 0.1% Cu from 42m (LSPC3) including:
-
15m @ 0.22% Cu from 42m
-
narrow intersections up to 2.32% Cu towards end of hole

Figure 4 – 3D magnetic model of Newmont drilling at Lamil 1 (colour by copper grade)
While copper exploration has not been the historical focus at Lamil, the geological processes to form high-grade copper mineralision have been active along a major regional gravity-lineament which is almost certainly representative of a major crustal structure.
Whilst there is a broad spatial relationship between copper anomalism intersected in the historic drilling and the Lamil magnetic anomalies, the Company believes that the magnetic anomalies may not be the direct primary target. Rather the magnetic anomalies may provide a general indication that mineralisation and related alteration has been focused in this area. The broad area outlined by the Lamil magnetic anomalies will be targeted by the Company in the next phase of exploration.
Airborne Electromagnetic Surveys (AEM) were used to define the initial drill target at Winu and various AEM tools are currently being assessed for deployment at Lamil.
Next Steps
The historical drill core from Newmont will be relogged and resampled where required. A detailed AEM survey, or potentially, a ground IP survey, will be completed by Encounter at Lamil to define targets for the next phase of drilling.
In addition, there is potential to introduce a suitable joint venture partner for the Lamil Prospects in the future, consistent with Encounter’s project generator model.

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 sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Historical drilling at the Lamil prospects was sampled by Newmont Australia Ltd. The drilling was completed over several drilling campaigns from 1984-1993. Drill core intervals selected for sampling varied from specific narrow intervals based on geological logging and routine 1m composite samples. Sampling, when completed, was half core. Not all drill core was sampled and in some holes sampling was selective. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used Where drill site locations were evident the collars were recorded by Encounter staff using a handheld GPS, which has an estimated accuracy of +/- 5m. Where collars could not not be found they were approximated based on the position of the historic drill sump. The estimated accuracy of these holes (noted in TABLE 1 in the main body of this document) is +/- 15m. |
|
| 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 The diamond core was drilled at either HQ or NQ diameter. Samples submitted were half core samples. |
|
| 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 refer to samples from the diamond or RC drilling. Diamond holes were either HQ or NQ sized holes. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed All zones of core loss were logged as individual units. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples Unable to determine from historical reports. |
|
| 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. To date, no detailed analysis to determine the relationship between sample recovery and/or and grade has been undertaken for this drill project. |
| Criteria | JORC Code explanation Commentary 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. Geological logging is carried out on all drill holes by Newmont geologists, with lithology, alteration, structure and sulphide recorded. Based on the information available in the historical reports these diamond holes were not orientated. 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 drill holes were logged in full by Newmont geologists. If core, whether cut or sawn and whether quarter, half or all core taken. The core samples reported in this announcement were half cut core. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. Unable to verify from historical geological reports. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Unable to verify from historical geological reports. Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. No QAQC samples were submitted with these holes. 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 submitted with these holes Whether sample sizes are appropriate to the grain size of the material being sampled. The sample sizes are considered appropriate to give an accurate indication of the gold and base metal anomalism and mineralisation at Lamil. The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. No information is available in the historic reports on the nature of the assaying completed. 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 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. No information is available in the historic reports on laboratory QAQC procedures. |

| Geology | Deposit type, geological setting and style of mineralisation The Telfer West project is situated in the Proterozoic Paterson Province of Western Australia. A simplified geological interpretation shows a domal feature with Isdell Formation in the core of the fold being overlain by Malu Formation and the Puntapunta Formation forming the uppermost unit. The Telfer West project is considered prospective for sediment – hosted ‘Telfer style’ gold-copper mineralisation and intrusive related copper-gold mineralisation. |

| 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. All reported assays have been length weighted, with a nominal 0.1g/t gold lower cut-off or 500ppm Cu considered anomalous in the context of the geological setting. No upper cuts-offs have been applied. |
| 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. Higher grade intervals that are internal to broader zones of gold - copper anomalism are reported as included intervals, using a lower cut-off of 1g/t Au or 1% Cu and no minimum width. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. No metal equivalents have been reported in this announcement. |
