Tennant Creek gold-copper project
1. Edna Beryl
Emmerson Resources Limited ("Emmerson") (ASX:ERM) is pleased to announce that final approvals have been received from the Northern Territory Government for production to commence at the Edna Beryl Gold Mine (see Figure 1 in the link below). This will be the first new gold mine in Tennant Creek for over a decade and is testament to the Government's recent announcements on revitalising the region as a major mining centre. The Government is also conducting a feasibility study into establishing a Central Milling Facility - which is expected to stimulate additional mine development and exploration in the region.
Mining at Edna Beryl East is being undertaken by an operator specialising in small mines (the Edna Beryl Mining Company) under a tribute agreement. The agreement relates to a 3D envelope around the shallow mineralisation (see Figure 2 in the link below). Drilling last year extended the mineralisation beyond this 3D envelope, opening up the possibility of either expanding the current mining area or, if the next round of drilling is successful, contemplating a larger scale development. A reverse circulation drill program commenced during the quarter and will test a number of drill targets that were generated from the application of an ultra-high resolution ground gravity survey completed earlier this year. In addition, three deep diamond drill holes aim to test the continuity of the ironstones and chlorite alteration some 350m below the surface.
The tribute agreement with the Edna Beryl Mining Company provides Emmerson with a number of advantages:
- A risk-free income stream from its non-core assets via a royalty agreement that is proportional to the final amount of extracted gold and Emmerson's equity in the Tennant Creek Mineral Field JV (which is currently 100%);
- Future access to refurbished underground workings for near mine exploration; and
- The opportunity to monetise other non-core assets within its extensive tenement holding, subject to formal agreements being executed.
Development drives have intersected visible gold on two levels and assay results from underground sampling of the 90m level development drive at Edna Beryl East correlate well with the bulk sampling of development ore on the ROM pad (see Figures 3 & 4 in the link below). Options to treat the ore are well advanced and include toll treatment or sale to third party mills. Longer term it is envisaged that the Central Milling Facility and/or refurbishment of the Emmerson Warrego plant will provide greater benefits to all stakeholders.
Edna Beryl represents the third discovery by Emmerson (and partners) of high grade, hematite-chlorite hosted gold and copper-gold mineralisation. It validates our science based approach to exploration through ushering in a new generation of deposits that have remained largely undetected by previous explorers.
2. Rover Project
Emmerson drafted and submitted an Application for the NT's CORE (Creating Opportunities for Resource Exploration) initiative which is designed to maximise opportunities for the exploration, discovery and development of new mineral and petroleum resources. The application was submitted on 26 April 2017, and Emmerson was successfully awarded $100,000 funding towards the proposed survey on 1 June 2017.
The application was for a program of 3D IP geophysics over a number of gold-copper targets within the Rover Mineral Field. The cover depth at Rover has historically been a major constraint in undertaking detailed exploration, which if analogous to the well explored Tennant Creek Mineral Field to the north, should yield multiple deposits. The survey aims to provide further geoscientific data to de-risk target generation through providing subsurface information on the depth of the cover, the unconformity between the Wiso Basin and Warramunga Formation and pinpointing sulphide rich ironstones.
The survey will be undertaken in two stages consisting of an initial 'Proof of Concept' over the known Rover 4 (R4) prospect and if positive, be followed by the next stage aimed at testing an inferred, metal fertile corridor that also hosts Rover 11, 12, 14 and 16. The survey is scheduled to commence in mid-July and be completed by mid-August.
The inclusion of this project under the Tennant Creek Mineral Field Earn-in and JV with Evolution Mining is further testament to the calibre and potential of this new acquisition. It not only provides funding by EVN toward the initial earn-in but positions ERM as the major player in one of Australia's highest grade goldfields.
3. Black Snake
A small program of pre-development RC drilling has confirmed the shallow, high-grade nature of the gold mineralisation (see Figures 5 & 6, Tables 4 - 7 in the link below). Samples from this drilling will now be composited and sent for metallurgical, ore and waste characterisation.
The Black Snake mineralisation is interpreted to strike East-North-East within a vertical dipping shear zone, and where gold occurs within hematite shale and veins that have yet to be closed off by drilling (see Figures 5 & 6 in the link below). The high-grade gold mineralisation at Black Snake is very typical of the Tennant Creek Mineral Field and is similar to Edna Beryl in being hematite dominant and thus gone undetected by previous explorers.
Permitting of the Black Snake Mine ahead of development is well advanced, with the Mine Management Plan and Heritage survey completed.
4. Other Small Mines
Planning and permitting is underway for mine development at Malbec and Chariot. It is envisaged that the development of these small mines will be via a similar Tribute style agreement to Edna Beryl however the commercial arrangements are yet to be finalised. This style of agreement has the following advantages:
- A risk-free, near term income stream from Emmerson's non-core assets via a royalty agreement (until EVN completes its earn-in, ERM receives 100% of its share flowing from this agreement).
- Future access to refurbished underground workings for near mine exploration.
- The opportunity to monetise a pipeline of non-core assets within Emmerson's extensive tenement holdings but utilising a dedicated independent small mines company.
5. September Quarter Activities for Tennant Creek and Rover Projects
The following activities are planned for the September quarter:
- Additional drilling at Edna Beryl, outside of the small mines envelope to test for extensions to the high grade gold zones intersected to date and regional tests of targets generated from the gravity survey.
- If results of the orientation, ultra-high resolution gravity survey at Edna Beryl are successful, then extensions of this survey will be undertaken to map out further hematite ironstones in fertile structural locations.
- Execute the 3D Deep IP survey at the Rover Joint Venture.
- Drill-Target delineation at the Rover Joint Venture, from the IP survey and also from the completed geological review which identified some outstanding targets from previous exploration work done by Andromeda (formerly Adelaide Resources).
- Continuation of mining within the Edna Beryl Tribute area and identification of processing options
- Continuation of the planning, permitting and approval process for the additional small mines Exploration remains fully funded under the $15M earn-in JV with Evolution.
New South Wales gold-copper projects
1. NSW General
Emmerson is pleased to announce the continuation of exploration over four of our NSW projects (see Figure 7 in the link below). These projects were generated from the application of proprietary, predictive 2D and 3D targeting models - developed in conjunction with our strategic alliance partner Kenex Limited. This alliance aims to greatly increase the success of predicting the next discoveries in NSW through identifying independent geological attributes that are highly correlated with mineralisation. Note: Kenex can earn up to a 10% interest in any tenements acquired upon achieving certain predetermined milestones (this does not apply to the Kadungle project).
Landowner/stakeholder engagement commenced over prioritised projects ahead of field work in EL's 8464 (Fifield) and 8465 (Temora) with early success in both verbal and signed access agreements, ahead of field mapping, sampling and rock chipping.
Exploration on our NSW projects is fully funded by Emmerson and at the appropriate stage, a suitable JV partner may be sought.
2. Kadungle Project
Emmerson's first drill hole at Kadungle in NSW (see Figures 8 & 9 in the link below) has intersected visible sulphides within an extensive zone of alteration. This drill hole supports the previous historical drilling where high-level epithermal veins were intersected with best assays of 12m at 7.73 g/t (KDD002) and 3m at 7.14 g/t Au (KRC019) (see Figures 8 and 9 in the link below). Similarly, deeper disseminated and veined copper-gold produced intersections of 37m at 0.23% copper including 6m at 1.1% copper (KDD013) and 154m at 0.12% copper and 0.37g/t gold (KRC019) (ASX- 4 October 2016).
This recent drill hole not only extends the known mineralisation but points to the potential for both high level (shallow) epithermal gold-silver and deeper porphyry copper-gold mineralisation. The alteration of upper level quartz-pyrite-hematite grading to deeper chlorite-epidote-quartz is consistent with this interpretation (see Figure 9 in the link below). Moreover, the intersection of mineralised hydrothermal breccia which cuts the volcanic breccia/diatreme (see Figure 8 in the link below); both containing disseminated chalcopyrite (assays pending) is very positive (see Figure 10 in the link below). In terms of scale, the discovery of further hematite bearing epithermal quartz veins, some 2.5 kms north at the Trig prospect provides some indication that this is a large mineralised system (see Figures 1 and 5 in the link below). ). Work is already underway to better define the geology and alteration assemblages.
Note the Kadungle project falls under an option agreement with Aurelia Metals and provides the right for Emmerson to earn up to 80% through spending $0.5m over a five year period.
3. September Quarter Activities for NSW Projects
The following activities are planned for the September quarter:
- Geophysical Modelling of the detailed high-resolution magnetic surveys is well underway over Emmerson's NSW projects at EL's 8465 (Temora) and 8464 (Fifield).
- Design and implementation of a 3D IP geophysical survey at Kadungle ahead of further drilling.
- Continuing landholder/stakeholder engagement over prioritised projects ahead of field work

About Edna Beryl Mineralisation
Edna Beryl was discovered by prospectors in 1935 and mined underground in the 1940s and 1950s to a maximum depth of approximately 50 metres. Production up until 1952 was reportedly 2,700t of ore at an exceptional grade of 53g/t gold.
More recent exploration in the Edna Beryl area between1996 and 2000 by Giants Reef Mining (GRM) outlined additional high-grade gold mineralisation below the historic workings and resulted in an estimate being reported in 1998 by independent consultants in accordance with the Australasian Code for Reporting of Identified Mineral Resources and Ore Reserves (JORC: 1998). While this estimate does not meet the minimum reporting requirements for a Mineral Resource under the current 2012JORC Code, Emmerson considers the Edna Beryl mineralisation to constitute an Exploration Target of 5,000t to 10,000t at 20 to 30 g/t gold, however cautions that the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to estimate a Mineral Resource and that it is uncertain if further exploration will result in the estimation of a Mineral Resource.

About Aurelia (ASX:AMI)
Aurelia Metals became a gold producer in 2014 and its flagship asset is the high-grade Hera gold-lead-zinc-silver mine in central NSW.
In FY 2016, the Hera mine produced 46,882 ounces of gold and 25,406 tonnes of lead-zinc concentrates from the processing of 308,118 tonnes of ore.
The Company is pursuing significant further improvements in the Hera operation including improved metal recoveries, increased throughput and operating cost reductions. Aurelia is also pursuing a near mine exploration programme, with a strong view on the capacity for Hera to evolve into a large scale, high-grade 'Cobar style' deposit.
Aurelia is also actively evaluating the evolving copper deposit at Nymagee with the potential that the Nymagee mineralisation may evolve into another 'Cobar Giant' similar to the world class CSA copper deposit located approximately 100km north-west along strike.
