Extensive Alteration and Copper Sulphides Intersected in Discovery Drill Hole at Kadungle
Extensive Alteration and Copper Sulphides Intersected in Discovery Drill Hole at Kadungle
Perth, Dec 13, 2017 AEST (ABN Newswire) - Emmerson Resources Limited ("Emmerson") (ASX:ERM) is pleased to announce preliminary results from two of the drill holes at its Kadungle, Mt Leadley prospect in NSW, where Emmerson can earn up to an 80% interest from Aurelia Metals by spending $0.5m over a five-year period. Kadungle and the adjacent Fifield tenements are one of four major projects held by Emmerson Resources in the highly prospective yet under explored Macquarie arc in NSW (see Fig 2 in link below). Whilst this arc hosts world class deposits of gold and copper-gold, it remains underexplored, mainly due to the challenges of exploring under younger cover. Emmerson and strategic alliance partner, Kenex Limited aim to validate a new approach to predicting the next big copper-gold discoveries in the region. This approach is probability based and utilises multiple independent data sets that are tested with respect to the known deposits to mitigate the challenges of exploring under cover.

- Early results from the first of the eight holes, 2000m drill program intersects extensive alteration and visible copper sulphides

- Drilling is still underway on the second drill hole with visible copper sulphide mineralisation increasing with depth

- The drilling is testing targets generated from the deep penetrating, Induced Polarisation geophysical survey combined with geological and alteration studies that point to a large underlying alkalic porphyry copper-gold system, with shallow epithermal gold veins over some 4km2

- A second drill rig will commence on a 5-hole program, some 2km north at the Trig prospect where gold in epithermal veins has recently been identified

Utilising this approach, Emmerson has picked up four large projects in what we believe are highly prospective areas for both shallow epithermal gold and deeper copper-gold. Exploration is underway across all four, with Kadungle being the most advanced.

Kadungle NSW - Drilling in Progress (see figure 3 in link below)

A recently completed IP geophysical survey and alteration mapping at the Mt Leadley prospect within the Kadungle project confirms the potential for shallow gold and deeper copper-gold mineralisation. The IP anomalies are apparent across five consecutive lines, over 1km in extent and within a previously identified zone of magnetite destruction (Fig 4). This is the first systematic exploration on this project and although there has been previous but limited drilling, this recent work extends the shallow gold and deeper copper-gold potential, particularly as most of the anomalies remain untested.

Drill hole KDD017 (still in progress) is aimed at testing both the IP and the increase in rank and intensity of alteration and copper mineralisation with depth, as the causative intrusion(s) is approached (see figure 5 in link below). This is supported by observations from the drill core (visible only) with shallow silicification and sericite-pyrite alteration, to pervasive chlorite-hematite, and now to deeper k-spar-pyrite-quartz-chalcopyrite. The increasing density of chalcopyrite - pyrite +/- quartz veins (visible estimates of 3 to 8 volume % of the drill core) with depth along with k-spar alteration is consistent with this model. The drill hole is currently at 525m down the hole (~450m below the surface) and still in mineralisation.

Drill hole KDD016 tested both shallow resistivity and chargeability anomalies within a broad zone of magnetite destruction, interpreted to represent hydrothermal fluids focussed within fault bounded breccias. The alteration mapping (ASD) from sparse historical drill holes support increasing alteration rank and intensity within this breccia and at depth. Pleasingly KDD016 confirms this zonation where alteration assemblages of quartz (silicification), chlorite, hematite and sericite also containing up to 25% fine disseminated pyrite is cut with intermittent veins of quartz-pyrite-chalcopyrite (visible estimates of less than 5 volume % of the core) (see figure 6 in link below).

Site preparation has now been completed at the Trig prospect ahead of mobilising a second drill rig later this week (access and weather permitting). This 5-hole program is aimed at testing the extent of gold in epithermal veins recently mapped on the surface and undercover by a Gradient Array Induced Polarisation (GAIP) survey. Note this prospect is some 2km north of Mt Leadley and has never been drill tested before - and if related provides an indication of the possible scale of the Mt Leadley-Trig mineralisation which puts it on scale with other similar deposits in the belt.

Drilling is anticipated to be finished prior to Christmas and assay results will be available in late January to early February 2018.

Emmerson's Managing Director, Mr Rob Bills commented:

"These early results at Mt Leadley, although preliminary, are very encouraging in confirming the existence of a large mineralised copper-gold system within our Kadungle tenements. The alteration and mineralisation from the drilling is consistent with our exploration model of a buried (oxidised, silica undersaturated) alkalic porphyry system which typically has great potential for not only copper but also associated gold - note assays will be required before the grade is established.

Drill hole KDD017 whilst still in progress, is encountering increasing intensity and rank of alteration plus copper mineralisation with depth. Drilling will continue on two shifts and a further rig is scheduled to commence at the Trig prospect later this week.

Whilst still early days in the program, we are optimistic given both the depth extent as revealed in drill hole KDD017 and size of the footprint of magnetite destruction at both Mt Leadley and Trig.

These positive results at Kadungle have implications to the rest of Emmerson's NSW projects, given they were targeted utilising the same parameters and methodology.

About Emmerson Resources Limited

Emmerson

Emmerson Resources Limited (ASX:ERM) (FRA:42E) recently commenced exploration on new gold-copper projects in NSW, identified (with our strategic alliance partner Kenex Limited) from the application of 2D and 3D predictive targeting models – aimed at increasing the probability of discovery. The highly prospective Macquarie Arc in NSW hosts >80Mozs gold and >13Mt copper with these resources heavily weighted to areas of outcrop or limited cover. Emmerson's five exploration projects contain many attributes of the known deposits within the Macquarie Arc but remain under explored due to historical impediments, including an overlying cover (plus farmlands) and a lack of exploration focus. Kadungle is a JV with Aurelia Metals covering 43km2 adjacent to Emmerson's Fifield project.

In addition, Emmerson is exploring the Tennant Creek Mineral Field (TCMF), one of Australia's highest-grade gold and copper fields producing over 5.5 Mozs of gold and 470,000 tonnes of copper from deposits including Warrego, White Devil, Orlando, Gecko, Chariot and Golden Forty. These high-grade deposits are highly valuable exploration targets, and to date discoveries include high-grade gold at Edna Beryl and Mauretania, plus copper-gold at Goanna and Monitor. These are the first discoveries in the TCMF for over a decade.
