ASX Announcement 16 October 2020
Drilling Update at Aileron Gold-Copper JV with Newcrest
-
Diamond drilling ended at the Aileron joint venture with Newcrest Mining located in the West Arunta region of WA
-
Following mechanical issues with the drill rig, a decision has been made to demobilise the rig and assay the completed section of the hole to 158m
-
First drill hole into an unexplored belt which is prospective for large scale gold-copper deposits
-
Initial observations from the Newcrest-funded drill hole include:
-
Shallow cover depth ~10m
-
Extensive hydrothermal alteration including zones of hematite alteration consistent with the IOCG model
-
Magnetite bearing, banded iron formation intersected at ~150m
-
Core samples are being transported to Perth with assays expected in November/December 2020
The directors of Encounter Resources Ltd (“Encounter / the Company”) are pleased to provide an update on the drill program at the Aileron gold-copper project held in joint venture with Newcrest Mining Limited (“Newcrest”) (ASX:NCM) located in the West Arunta region of Western Australia.
Commenting on the drilling at Aileron, Encounter Managing Director Will Robinson said:
“This hole at Aileron is the first drill hole into a remote and unexplored belt. Despite mechanical issues with the rig, the hole appears to have just entered the southern margin of the modelled magnetic anomaly. A decision has been made that the best course of action at this time is to end the current program and assay the completed section of the hole”
Diamond Drilling Update
The Aileron joint venture is located in the West Arunta region of WA, ~600km west of Alice Springs. The project contains a number of structural targets identified through aerial magnetic surveys, including a discrete magnetic anomaly consistent with the scale of an Ernest Henry or Carrapateena style goldcopper system (Figure 1).
There has been no previous mineral exploration on the project and EAL_001 is the first drill hole into an unexplored belt which is prospective for large scale gold-copper deposits.
Diamond drilling commenced in October 2020, but following mechanical issues with the drill rig, a decision has been made to demobilise the rig and assay the completed section of the hole to 158m.

The initial observations from the drill hole include:
-
Shallow cover depth (10m) – opening up potential for application of surface sampling and shallow geochemical drilling.
-
Extensive hydrothermal alteration including zones of hematite alteration consistent with the IOCG model (see Photo 1).
-
Magnetite bearing banded iron formation (BIF) intersected at ~150m (see Photo 2) containing high magnetic susceptibility readings consistent with the modelled anomaly. The centre of the magnetic anomaly was modelled to be intersected at ~300m downhole.
Core from the completed 158m of drill hole EAL_001 will be transported to Perth with assays expected in November/December 2020. Following receipt of assays future work programs for Aileron will be designed.

About Encounter
Encounter Resources Limited is one of the most productive project generation and active mineral exploration companies listed on the Australian Securities Exchange. Encounter’s primary focus is on discovering major gold deposits in Western Australia’s most prospective gold districts: the Tanami, the Paterson Province and the Yilgarn.
The Company is advancing a highly prospective suite of projects in the Tanami and West Arunta regions via joint ventures with Australia’s largest gold miner, Newcrest Mining Limited (ASX:NCM).
Complementing its expansive gold portfolio, Encounter controls a major ground position in the emerging Proterozoic Paterson Province where it is exploring for copper-cobalt deposits with highly successful mining and exploration company IGO Limited (ASX:IGO), and intrusive related copper-gold deposits at its 100% owned Lamil Project.
In addition, project generation activities in the Northern Territory utilising new Geoscience Australia datasets has resulted in Encounter securing the first mover Elliott and Jessica copper projects. Elliott is being advanced in partnership with BHP via an option agreement to enter an earn-in and joint venture.

SECTION 1 SAMPLING TECHNIQUES AND DATA
| SECTION 1SAMPLING TECHNIQUES AND DATA | |
|---|---|
| Criteria | JORC Code explanation Commentary 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. The Aileron project was sampled by Encounter using diamond drilling. A single hole program was completed to a total depth of 157.8m of diamond drilling. The diamond hole was designed to test a discrete high amplitude magnetic anomaly defined in regional aeromagnetics Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used Drill hole collar location was 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 Not applicable as the diamond drill core has not been sampled 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). The hole was PQ rough cored to a depth of 13m then HQ cored to the EOH. Diamond drill core is orientated using a Reflex ACT3 tool. Method of recording and assessing core and chip sample recoveries and results assessed Sections of lost core were minimal and were noted by the diamond drillers. Measures taken to maximise sample recovery and ensure representative nature of the samples Drilling of the cover and clay saprolite was rough cored to provide some sample with recovery approximately 75% with the remainder of the holes being drilled conventional with core recovery +95%. 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.
