Drilling underway to target gold reefs at East Thomson’s
A 5,000m RC/aircore drill program at East Thomson’s Dome and Telfer West has commenced and will include:
1. RC drilling of the near surface, high grade gold reefs discovered at the Fold Closure prospect at East Thomson’s Dome including:
-
2.9m @ 7.7g/t Au from 127.1m incl. 0.45m @ 25.4g/t Au from 129.55m to end of hole (“EOH”) in ETG0053
-
2.5m @ 7.3g/t Au from 11.4m, part of 26.6m @ 1.0g/t Au from 4.2m in ETG0055 (see ASX announcement 14 September 2017)
2. RC drilling up dip and along strike of the newly discovered gold reef 500m north-west of the Fold Closure prospect at ETD:
- 2m @ 26g/t Au from 178m, part of 6m @ 9g/t Au from 178m to EOH in ETG0045 (see ASX announcement 16 August 2017)
3. RC drilling of the gold stockwork corridor at Telfer West to test a recently identified surface geochemical anomaly
4. Aircore drilling of new targets identified at ETD and Telfer West
The directors of Encounter Resources Ltd (“Encounter / the Company”) are pleased to announce the commencement of a 5,000m RC/aircore drill program at the East Thomson’s Dome (“ETD”) and Telfer West Gold Projects. The program will be completed within the next six weeks.
Commenting on the upcoming program, Encounter Managing Director Will Robinson said:
“We are excited to commence the RC drill program on the back of last month’s discovery of multiple new high grade gold reefs at East Thomson’s Dome project, located 5km north-west of the Telfer gold-copper mine. The program will include detailed drilling at the Fold Closure prospect to determine continuity of mineralisation and as a prelude to potential resource drilling. We will also complete additional drilling adjacent to the new reef discovered in ETG0045 (6m @ 9g/t Au from 178m to end of hole).”
ETD - Fold Closure prospect – High grade reef system
Four diamond drill holes were completed by Encounter at the Fold Closure prospect in August 2017. Three of the four holes were drilled immediately south-east of a series of outcropping high grade gold reefs where drilling in the 1990s defined high grade near surface reef mineralisation including (see ASX release 14 February 2017):
-
4m @ 29 g/t Au from 31m in NTR 5
-
2m @ 33 g/t Au from 22m in NTR 12
-
10m @ 9.8 g/t Au from 16m in NTR 17 incl. 2m @ 45.8 g/t Au from 20m
-
• 2m @ 76.2 g/t Au from 35m in NTR 57
-
• 7m @ 17.1 g/t Au from 16m in NTR 61 incl. 3m @ 37.6 g/t Au from 19m
Diamond holes ETG0053, ETG0054 and ETG0055 drilled by Encounter all intersected oxidised, reef-style gold mineralisation and returned high grade gold intersections including:
-
2.9m @ 7.7g/t Au from 127.1m incl. 0.45m @ 25.4g/t Au from 129.55m to EOH in ETG0053
-
• 1m @ 3.2g/t Au from 80m in ETG0054
-
2.5m @ 7.3g/t Au from 11.4m, part of 26.6m @ 1.0g/t Au from 4.2m in ETG0055
It appears the reef mineralisation at ETD is stacked, with more than one mineralised horizon intersected in the diamond drill holes. These high grade reefs at the Fold Closure prospect remain open down dip and along strike.
The current RC program will be drilled on a notional 40x40m spacing to test for continuity and test along strike and down dip for further extensions of the high grade mineralisation.
If successful, this drilling will be followed by resource drilling at ETD.
Follow up drilling of the gold reef discovered in ETG0045 at ETD
Encounter completed a program of 18 broad spaced RC holes for 3,816m over six 200m to 800m spaced traverses. This drilling was completed in July 2017 and was focused on the eastern half of a 2km long surface geochemical anomaly. Holes were planned to a nominal depth of 200m which was thought to be sufficient to test the important geochemical horizon at the base of oxidation. Anomalously deep oxidation at ETD resulted in many of the RC holes finishing above the target horizon.
Although many holes did not test the base of oxidation, the results received were highly encouraging with a well mineralised (+1g/t Au) trend defined over a strike length of +500m. In particular, RC drill hole ETG0045 finished in 6m @ 9.0g/t Au from 178m to EOH including 2m @ 26g/t Au from 178m. In September 2017, ETG0045 was extended with diamond drilling to 396m and assays from the diamond extension are expected later in October 2017.
The current RC drill program will close up drill spacing around the high grade gold intersection in ETG0045 as well as extending the RC drill pattern west over an untested portion of the surface geochemical anomaly.

Gold Stockwork Zone at Telfer West
In July 2017, a program of RC drilling was completed at Telfer West which included two RC drill holes (ETG0067 and ETG0068). These holes were drilled 800m south-east and along strike of the Egg prospect where hole ETG0002 was drilled in December 2016. ETG0002 intersected an 80m wide, depth extensive zone of stock-work style gold mineralisation that included:
- 38.6m @ 1.0g/t Au from 333m (including 4.2m @ 3.2g/t Au from 333.5m) and 36m @ 0.6g/t Au from 396m (including 3.2m @ 3.3g/t Au from 415.2m) (see ASX release 19 January 2017)
The first RC hole in the new area, ETG0067, returned 122m @ 0.2g/t Au with gold mineralisation strengthening towards the bottom of hole (see ASX release 31 July 2017). The RC pre-collar of ETG0068 contained a thick zone of oxidised gold mineralisation of 30m @ 1.1g/t Au from 96m which is located to the north-east of the new stock-work zone (see ASX release 31 July 2017).
ETG0067 and ETG0068 were extended with diamond tails in August 2017. Assay results from the diamond tails included sporadic gold mineralisation down hole but did not include significant extensions to the gold mineralisation drilled in the pre-collars. Assay results from the additional RC/diamond drill hole (ETG0070) that was completed 80m north-east of ETG0068 remain pending and will be received later in October 2017.
In addition, a surface geochemical program has been completed along the interpreted surface expression of the gold stockwork system at Telfer West. The program was successful in highlighting the stockwork zone surface position with assays up to 100 times background collected.
Soil samples collected over the 800m gap between the two competed drill lines has identified a coherent gold anomaly that has not been tested by previous drilling (Figure 2). The current drill program will test the centre of the new anomaly, 400m north-west of ETG0067, ETG0068 and ETG0070 and 400m south-east of the drill line containing ETG0002.

Aircore Drilling at Telfer West and ETD
The current drill program will include initial aircore drilling of three structural targets identified at Telfer West. These targets are located to the north-east and south of the main stockwork corridor (see Figure 3).
Detailed surface geochemical sampling at a 40x40m spacing was recently completed over a 600m section of the 2km regional anomaly at ETD. This program was designed to locate additional subcropping high grade reefs within the broader regional anomaly. A zone of elevated soil anomalism has been identified to the north-east of the Fold Closure prospect (Figure 1). A program of aircore drilling will be completed in this area to determine the significance of these anomalous results.

| 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. New information reported in this announcement relates to a soil sampling program at East Thomson’s Dome and Telfer West. A total of 132 samples were collected at Telfer West in this program with sample spacing of 100m spaced lines and 20m spaced samples. A 359 sample program was completed at East Thomson’s Dome on a 40m by 40m grid. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used Soil 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 Soil samples collected by Encounter at designated sample locations and sieved in the field to -250 micron. Approximately 300g of sieved material was then bagged in pre-number geochemical bags. The samples from the soil sampling were sent to Bureau Veritas Minerals Pty Ltd Laboratories in Perth, where they were dried, pulverised and split to produce a 40g sub-sample for Aqua Regia digest and ICP analysis. |
