ASX ANNOUNCEMENT / MEDIA RELEASE
ASX:ABU
18 July 2016
Exploration Update – Suplejack Project
ABM Resources NL (“ABM” or the “Company”) is pleased to report that the recently announced (ASX 2 June 2016) reverse circulation (RC) drilling program at the Suplejack Project has been completed with a total of 84 holes for 8,346 metres drilled. All assay results from the Tethys Prospect, which is situated on the Hyperion trend to the east of the current resource (see appendix for details) and was the primary target of this drilling program, have now been received.
Highlights
-
22 of the 33 holes completed at Tethys returned significant gold intercepts, including:
-
Hole TYRC100001 – 17 metres at 5.74g/t gold
-
Hole TYRC100003 – 26 metres at 2.56g/t gold
-
Hole TYRC100006 – 21 metres at 2.89g/t gold
-
Hole TYRC100028 – 7 metres at 13.17g/t gold
-
Hole TYRC100030 – 18 metres at 4.52g/t gold
-
The drilling results confirm that gold mineralisation on the Hyperion trend extends over a strike length of at least 1,300 metres
-
All mineralisation at Tethys/Hyperion remains open at depth
-
Follow-up RC and diamond drilling is planned
The Tethys Prospect is situated within the Suplejack Project area on exploration license EL9250 in the northern Tanami. The latest drilling indicates that Tethys represents a significant extension of the Hyperion mineralised system.
Geology at Hyperion consists of steeply dipping sedimentary rocks (sandstone and shale), dolerite and basalt. Mineralisation is considered to be associated with a granite dyke or sill and is typically evidenced by quartz veining and elevated alteration of the host rocks. The upper parts of the system are generally leached, with mineralisation tenor increasing from 20 metres depth.
In the recent drilling program, 33 RC holes were completed for a total of 3,288 metres. The drill holes were designed to confirm and extend gold mineralisation identified by air-core drilling in 2015 (ASX 26 August 2015). This objective was achieved with 36 significant gold intercepts returned from 22 of the 33 completed holes. Collar positions for the new RC holes are shown in Figure 1 below with selected major intercepts labelled. Drill hole coordinates and details of all significant intercepts are presented in Tables 1 and 2 in the appendix.

Figure 1: Hyperion Trend Drill Collar Plan with Major Drill Intercepts
Two holes drilled down dip from the initial air-core discovery holes on cross-section 613480mE extended mineralisation at depth, as shown in Figure 2. Two holes drilled 50 metres to the west returned broad, high grade intercepts, as shown in Figure 3, indicating potential for extending mineralisation further towards the current Hyperion resource.

Drilling also extended mineralisation eastward as far as 614180mE, where some of the strongest intercepts were returned, as shown in Figure 4. However as can be seen in the cross-section, there is an apparent discontinuity in the interpreted mineralisation, with the main intercept in hole TYRC100030 (18 metres at 4.52g/t) not in alignment with mineralised intersections in holes TYRC100028 and TYRC100029. This suggests possible displacement by faulting, a sudden flattening of dip or emergence of an additional parallel body of mineralisation.

Figure 4: Tethys Cross-section at 614180mE
It is intended to drill an additional two RC holes on this section up and down dip of TYRC100030 and a line of three holes 50 metres along strike to both the east and west in order to help interpret the apparent change in geometry and potentially extend the high grade mineralisation intersected in this hole. The RC drilling rig utilised in the recent program has remained in the area, which should enable this follow-up drilling to be carried out in the near term.
Significant mineralisation has now been identified on the Hyperion trend over a strike length of 1,300 metres, albeit with three apparent breaks in high grade mineralisation as shown in the long section in Figure 5. There is currently a 200 metre gap in drilling between TYRC100030 and a line of three holes to the east
that did not generate any significant intercepts, providing scope for a material extension in this direction. It is not yet known whether the line of sub-grade holes on section 614380mE represents the potential limit of mineralisation or is simply another break in the strongly mineralised system.

Figure 5: Hyperion long-section with drill hole pierce points
Mineralisation on the Hyperion trend remains completely open at depth, with the deepest hole within the current resource little more than 200 metres below surface and drilling at Tethys generally shallower than 100 metres.
A detailed mapping and re-logging program is currently underway at Suplejack in order to develop an alteration profile for the Hyperion area that may assist in targeting further mineralisation. A limited diamond drilling program is also proposed to further improve the company’s understanding of the geology of this mineralised system.
