Emmerson’s Managing Director; Mr Rob Bills commented :
“These high-grade results from our Tennant Creek project speak for themselves and support our strategy of building a pipeline of high-grade, high-value mines which feed into the Mine Schedule. Where our partner, Territory Resources Limited (“Territory”) is undertaking various optimisation studies ahead of permitting and development. Emmerson receives a low-risk return either from 12% and 6% of the gold produced at the Edna Beryl and Chariot projects respectively, or a 25% share of the profit from the other seven projects in the Mine Schedule.
Emmerson owns 100% of the Mauretania project and plans to undertake further work to maximise value. In contrast, The Susan project is within the JV area with Territory and is where Territory are funding $5m over 5 years to earn a 75% equity interest.
As previously announced the Edna Beryl Mining Company, now owned by Territory is developing the high-grade, Edna Beryl gold mine. The first parcel of ore produced from the mine is currently being toll treated offsite while Territory complete refurbishment of the Warrego mill with completion forecast by year-end. The development of the Edna Beryl mine not only

provides a low-risk return to Emmerson but also an opportunity to better understand the geology and gold distribution via underground drilling and development. Something that has been instrumental in realising the potential of many of the other historical high-grade mines in the Tennant Creek Mineral Field.”
Northern Project Area Drilling – ERM 100%
A total of 15 holes for approximately 1,700m of Reverse Circulation (“RC”) drilling was completed across three projects in December 2018 (Figure 1). The best assay results were received from Emmerson’s 100% owned Mauretania prospect where drilling was aimed at better defining the shallow, oxide and deeper primary gold zones. Despite difficult drilling conditions which necessitated abandoning and redrilling a number of the holes, these exceptionally highgrade results have increased our confidence in the potential for economic mineralisation in both the shallow oxide and deeper, primary gold zones.
As an example, drill hole MTRC034 was abandoned (due to drilling issues) in broken and brecciated hematite ironstone, with assays of 11m at 54.1g/t gold. Redrilled in hole MTR031 returned 22m at 36g/t gold which included 6m at 122g/t gold that terminated in ore (Figures 2 & 3). Drill hole MTRC028 was aimed at testing the deeper primary mineralisation however, intersected significant copper of 9m at 1.05% copper from 131m. Given the typical metal zonation of copper higher in the system (and closer to the surface) than the gold and bismuth, suggests potential for primary gold at depth. Supported in the next section to the south (Figure 4), where previous drilling intersected 10m at 7.6g/t gold from 171m, including 5m at 13.4g/t gold (ASX:21/06/2018).
Due to challenging drilling conditions, the program was halted early and will require a more powerful RC rig before proceeding. Or alternatively, looking at commercial arrangements to undertake the deeper drilling during development and mining.
Note: Mauretania is a recent green fields discovery, identified from recognising that high-grade gold (and copper), like Emmerson’s recent discoveries at Edna Beryl and Goanna are associated with very oxidised, hematite fluids. These styles of deposits are characterised by very high grades of gold (and in the case of Goanna, copper), strongly controlled by structure and thus represent difficult targets to intersect from surface drilling. By virtue of their association with hematite, they present as weak magnetic anomalies and in the case of Edna Beryl, an associated gravity anomaly. Furthermore, unless these deposits breach the surface, they display very restrictive gold, copper and bismuth geochemical footprints (as illustrated in Figure 2)
Southern Project Area (SPA) – Territory Earning 75%
Drilling in the SPA is part of the $5m earn-in funded by Territory and aimed at “growing” known gold mineralisation around the historic mines that are in the Mining Schedule.
Thus some 76 drill holes for approximately 3,000m were completed across several shallow oxide gold projects including Black Snake, The Susan and the Three Thirty prospects.
With many assays still outstanding, early results from The Susan prospect show great potential for shallow, high-grade gold in the oxide zone. Exemplified by drill holes SS001 and SS003 which intersected 11m at 48g/t gold and 8m at 16g/t gold respectively (Figures 5 & 6).
The early prospectors (from 1955-1960) sunk a small shaft to follow visible gold associated with hematite ironstone in the oxide zone. Mining records indicate production of 120 tonnes @ 23.5g/t gold but mining was curtailed due to water ingress on intersecting the water table at 42m.

Given these positive drill results and the limited historical exploration, it is likely that further predevelopment drilling will be undertaken as part of earn-in expenditures by Territory.
Upcoming Activities at Tennant Creek
– Edna Beryl Gold Mine Territory are the operators and managers (ERM receive 12% of the gold produced)
With the spectacular gold grades encountered during mining on the lowest 80m level at Edna Beryl (figure 7), deepening of the existing shaft and adding a further sub level is currently being evaluated. In addition, an exploration drill drive will be developed toward the Edna Beryl West mineralisation on the new 90m level to accommodate underground drilling. This will assist in understanding the grade distribution of the gold and geology ahead of establishing a Life of Mine plan. Note that under the terms of the agreement with the Edna Beryl Mining Company (now owned by Territory), Territory are responsible for all development, mining and processing which includes the development of the 90m exploration drive towards Edna Beryl West. Emmerson are responsible for the underground drilling and look forward to getting underway as we believe there is good potential to significantly expand the very high-grade mineralisation.
– Southern Project Area Territory Earning 75%
Further drilling is currently being planned across many of the projects in the Mine schedule, including drilling at Eldorado, Black Snake and The Susan. Mine planning, optimisation studies and permitting continue.
Corporate
After due consideration to the capital-intensive phase that our strategic alliance partner, Territory has committed to the Tennant Creek Project, Emmerson has agreed to restructure the timing of the second tranche share placement of $1,000,000 previously announced.
Territory have made an initial $300,000 progress payment toward the second tranche and the restructure grants Territory additional time to subscribe for the shares under the Subscription Agreement.
The recent floods in Cloncurry has significantly delayed the toll treatment of the first parcel of Edna Beryl ore. This restructure recognises these unforeseen delays.
Fully paid ordinary Shares (9,661,836 Shares) at an issue price of $0.1035 per Share will be issued following receipt of the full subscription amount of $1,000,000.
About Emmerson Resources and its New South Wales and Tennant Creek Projects
Emmerson is fast tracking exploration across five exciting early-stage 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 underexplored due to historical impediments, including overlying cover (farmlands and younger rocks) and a lack of exploration. Kadungle is a JV with Aurelia Metals covering 43km[2] adjacent to Emmerson’s Fifield project.

==> picture [75 x 46] intentionally omitted <==
In addition, Emmerson has a commanding land holding position and 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 two decades.
Emmerson recently announced the formation of a strategic alliance with Territory Resources to build a central mill in Tennant Creek to support the processing from Emmerson’s small gold mines and other third-party feed. This alliance also extends to a $5m earn-in by Territory Resources over Emmerson’s southern tenements (where ERM is the Operator and Manager) plus a Mining Joint Venture over a portfolio of Emmerson’s small mines that is on a 75/25 profit share basis, except for the Edna Beryl and Chariot mines which respectively have a 12% and 6% gold production royalty.
Emmerson is led by a board and management group of experienced Australian mining executives including former MIM and WMC mining executive Andrew McIlwain as non-executive chairman, and former senior BHP Billiton and WMC executive Rob Bills as Managing Director and CEO.

These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • 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 (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30g 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 (eg submarine nodules) may warrant disclosure of detailed information. |

SECTION 1.2 REPORTING OF EXPLORATION RESULTS – THE SUSAN PROJECT AREA – RC DRILLING (Criteria listed in the proceeding section may apply to this section)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• The Susan Exploration Target_is located within Mining Licence Central 524 (ML C524). • _The Susan Exploration target_is located on Vacant Crown Land, Parcel 04440. • Mining Licence Central 524 (ML C524).is 100% held by Emmerson Resources Limited. • Land Access is secured through Emmerson’s Pre-Existing Tenements Agreement (PET) with the CLC which is in good standing. • Land Access is secured through Emmerson’s Land Access Agreement signed by the owners of the Tennant Creek station. • Heritage surveying (assisted by the Central Land Council) was conducted prior to any exploration being conducted within_The Susan Project Area. • Sacred Site Certificate Number 2016-114 was issued post field inspection allowing field exploration and drilling to commence. • One restricted work area is identified over The Susan ironstone outcrop. Drilling was approved under The Susan outcrop. • Emmerson do not believe that the two identified exclusion zones will impact of future exploration of_The_ Susan Project Area. • The tenement is in good standing and no known impediments exist. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Prospecting via a shallow vertical shaft (30m) produced a reported 120 tonnes of ore at a grade of 23.5 g/t gold (91 0z) from 1955-1960. • Normandy Mining completed regional mapping and reconnaissance drilling over the Susan Project area. This work was completed during 1995-2000. • Emmerson Resources commenced exploration at_The_ _Susan Exploration Target_in 2016. RC drilling 10 holes for 1,065 metres (SSRC011- 012) & (SSRC014-021) and one diamond (NQ) drill hole for 549.2 metres. • Outcrop mapping and rock chipping was undertaken by Emmerson Resources. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The reader is referred to AusIMM Monograph 14 (Geology of the Mineral Deposits of Australia and Papua New Guinea), Volume 1, pp. 829-861, to gain an introduction to the regional geology and styles of gold-copper mineralisation of the area. • In 1995 the Northern Territory Geological Survey released a geological map and explanatory notes for the Tennant Creek 1:100,000 sheet, which covers the area of the license. |

| • The rocks of the Warramunga Formation host most of the ore bodies in the region and underlie the Exploration License. • Mineralisation is considered to be Proterozoic Iron Oxide Copper Gold (IOCG) mineralisation of similar style and nature to other mineralisation / deposits in the Tennant Creek Mineral Field. |
||
| Drillhole information | • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: o easting and northing of the drillhole collaro elevation or RL of the drillhole collaro dip and azimuth of the holeo downhole length and interception deptho hole length. |
• A list of the drillholes and the drillhole collar locations and elevation, the total depth, drill type and dip and azimuth and assay results are included as a Table in the body of the text. |
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• Mineralized intersections are reported as down hole intervals and not weighted averages. • Please refer to the table of significant results in the body of the text for detail on cut off grades and mineralised widths. • These results are exploration results only and no allowance is made for recovery losses that may occur should mining eventually result, nor metallurgical flow sheet considerations. • Cut-off grades have been used for reporting of exploration drill results and are defined in the Table of Significant results. |
| Relationship between mineralization widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drillhole angle is known, its nature should be reported. • If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (eg ‘downhole length, true width not known’). |
• Mineralisation identified at The Susan _Exploration Target_is contained within hematite- magnetite ironstone (see cross – section in the text). • The ironstone dips 85 degrees to the south and strikes east-west. Magnetic modelling suggests the ironstone has a strike length of 30m and the modelled body plunges to the southwest. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drillhole collar locations and appropriate sectional views. |
• Refer to Figures in body of text. |
| Balanced reporting | • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• All available results are reported. Note that many of the 4m composite samples have not been received or provided by Territory Resources to Emmerson Resources Ltd. Refer to Table 2 in the text. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not |
• Not Applicable. |

| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• Collection of a 100kg composited bulk metallurgical sample from recent drilling. • Ore and waste characterisation sampling to assist with production of a Mining Management Plan. • Additional drilling is required to establish grade and volume of the mineralised body. • Geotechnical investigations. |
