Bonanza gold intercept from first diamond drill hole at Mauretania, Tennant Creek
Highlights
Extension of diamond drill hole MTDD010 returns the first bonanza gold intercept in the sparsely drilled primary gold zone of:
- 3.95m at 57g/t gold, 0.22% bismuth, 20.6g/t silver and 0.23% copper from 207m including:
o1m at 102 g/t gold, 47g/t silver and 0.6% bismuth, ando0.8m at 135.5 g/t gold, 40.2 g/t silver and 0.34% bismuth
Previously reported copper mineralisation in the shallower oxide zone of :
-
7m at 0.81% copper from 88m including:
-
1m at 1.66% copper (ASX 17 February 2021)
-
Assay results from the remainder of the current 1700m program expected in late July/early August
-
Next drill program scheduled for Black Snake and Susan following previous high grade gold intersections (ASX:25 May 2021)
-
Ultra-High-Resolution drone magnetic survey 50% complete and aimed at generating new greenfield discoveries
Emmerson’s Managing Director, Rob Bills commented:
“This first drill intersection in the current program demonstrates the unexplored potential beneath the known oxide- gold mineralisation at Mauretania. Previous drilling was focussed on delineating the shallow mineralisation amenable to open pit mining; however, this bonanza intersection now greatly expands the potential for high-grade gold in the underlying primary zone - some 100m below the current modelled open pit floor.
Once all the assay results are received, further drilling will be planned to test for extensions of this primary mineralisation that is open in all directions but likely controlled by the WNW and ENE faults – representing the feeder or conduits to the mineralising fluids.
Emmerson has a strong pipeline of high-grade gold, copper, and cobalt projects at various stages of exploration. The greenfields discovery at Mauretania is one of our most advanced projects with open pit optimisation studies to benefit from the results of this current drill program.
Our Joint Venture partner, TCMG, is fully funding the drill program at Mauretania as part of the $5.5m earn-in over the Northern Project Area at Tennant Creek. Given the favourable economics of the proposed Mauretania open pit, this project is a priority in the TCMG mining schedule. TCMG are in the advanced stages of a feasibility study to build a central processing hub at Tennant Creek. This hub will process ore from multiple sources in the Tennant Creek district and is forecast to be operating in 2022.”

– Mauretania Drilling testing for extensions to the primary gold mineralisation
Mauretania is located within the Northern Project Area (NPA) of the Tennant Creek Mineral Field (TCMF) (Figure 1), where historically drilling has been focussed on the shallow oxide mineralisation (figure 2). Diamond drill hole MTDD010 was prematurely terminated last year at 106m due to the impending wet season. This drill hole has now been completed and is one of only three that have intersected the primary gold zone (figure 3). The results together with intersections of similar primary mineralisation from diamond drill hole MTDD009 (ASX: 17 February 2021) of:
-
8.8m at 3.44g/t gold from 181m including:
-
2m at 9.0g/t gold from 186m
-
plus, a further shallow high-grade copper zone of:
-
12m at 2.5% copper, 0.26g/t gold and 0.14% cobalt from 85m including:
-
2m at 4.1% copper from 90m and
-
9.5m at 0.17g/t gold from 60m
-
are highly encouraging. Supporting the typical metal zonation in the TCMF of near surface bonanza style oxide gold, followed by copper at the base (or lateral) and primary gold below.
The mineralisation in drill hole MTDD010 is some 100m below the oxide gold and copper zones, but within the footwall of a massive hematite +/- magnetite ironstone. It consists of 7m of brecciation and intense chlorite alteration with hematite and magnetite stringers (figure 4). Thus, future exploration in the primary zone will be focussed on pinpointing these structurally controlled, brecciated, feeder conduits – where the mineralised fluids have been channelled into the chemically reactive ironstones.
The remainder of the program at Mauretania was Reverse Circulation (RC) drilling, consisting of ten step out holes to establish the lateral extent of the upper oxide mineralisation, prior to finalising the design of the open pit (Figure 3). This program also consisted of geotechnical drilling that will feed into the final pit design.
Mauretania is a greenfields discovery that recognised the association between high-grade gold, copper and hematite ironstones that had largely gone undetected prior to Emmerson’s entry to the Tennant Creek Mineral Field in 2008. The hallmark of the Company’s discoveries at Edna Beryl, Goanna, Monitor and now Mauretania include the exceptional grade of both copper and gold and their association with hematite dominant ironstones.

Emmerson and TCMG to drive aggressive gold exploration in 2021
As previously announced, Emmerson has entered into a Strategic Alliance at Tennant Creek with Tennant Consolidated Mining Group (TCMG), which includes the following:
-
$10.5m Exploration Earn-in and JV (EEJV) across both the Northern Project (NPA) and Southern Project (SPA) areas
-
A Small Mines JV (SMJV) with a free carried 6% gold gross revenue royalty for production from Small Mines (<250,000oz); and
-
A Major Mines (MMJV) interest whereby Emmerson retains up to a 40% interest in any Major Discovery (>250,000oz gold equivalent)
This Strategic Alliance establishes a funded pathway for the development of Emmerson’s high-grade gold projects and provides substantial new funding for exploration to continue to build and advance the resource pipeline.
As part of this funding, and consistent with Emmerson applying new technology to make new discoveries, a large drone magnetic survey is underway. The resolution of this survey is far superior to historic, fixed wing surveys due to the drone being able to fly 15m above the ground and on 10m spaced lines.
Emmerson retains 100% ownership of the Jasper Hills and Edna Beryl projects and is advancing these through to planned drilling activities in 2021.
Next Steps – TCMG Joint Venture
Emmerson and TCMG are advancing Tennant Creek on two major fronts:
-
Undertaking advanced scoping studies on existing projects such as Mauretania, Chariot, Malbec West and Black Snake – it is anticipated these will advance to JORC compliant resource estimates in late 2021 and will provide feed for the central mill, plus support a “see through valuation” of the emerging Emmerson royalty business. Noting that under the SMJV, the costs associated with this phase of work are covered 100% by TCMG.
-
Exploration and discovery of new gold projects and/or extensions to existing projects. In the first instance this will include drill programs at Black Snake, Susan and further drilling at Mauretania. New technology such as the Ultra High Resolution Drone magnetic survey is aimed at pinpointing new green field opportunities. Emmerson remain the managers and operators of the EEJV until TCMG have met their earn-in commitments.

About Emmerson Resources, Tennant Creek and New South Wales
Emmerson has a commanding land position and is exploring the Tennant Creek Mineral Field (TCMF), one of Australia’s highest-grade gold and copper fields that has produced over 5.5Moz of gold and 470,000t 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 discoveries were found utilising new technology and concepts and are the first discoveries in the TCMF for over two decades.
A recent rush of new tenement applications by major and junior explorers in the Tennant Creek district, not only highlights the prospectivity of the region for copper and gold but also Emmerson’s strategic 1,800km[2] land holding.
In addition, Emmerson is fast tracking exploration across five early-stage gold-copper projects in NSW, identified (with our strategic alliance partner Kenex/Duke Exploration ASX: DEX) from the application of 2D and 3D predictive targeting models – aimed at increasing the probability of discovery. Duke can earn up to 10% (to pre BFS) of any project generated providing certain success milestones are met.
The highly prospective Macquarie Arc in NSW hosts >80Moz 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 effective historic exploration.

Section 1: Sampling Techniques and Data – MAURETANIA EXPLORATION TARGET – MTDD009 and MTDD010 DIAMOND DRILLING
| Criteria | **JORC Code explanation ** | Commentary |
|---|---|---|
| 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 downhole gamma sondes, or handheld XRF instruments, etc). 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 (e.g., ‘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 (e.g., submarine nodules) may warrant disclosure of detailed information. |
• The_Mauretania Project_holes have been sampled using Diamond (DDH) drilling techniques. MTDD009 was drilled with a total depth of 214m. MTDD010 have been partially drilled down to 106.5m in 2020, drilling resumed in May 2021, drilled to 220.4m. MTDD009 and MTDD010 are vertical holes to confirm shallow oxide gold mineralisation and extended to test for deeper, primary gold mineralisation confirmed by previous drilling. • Diamond core has been logged for lithological, density, magnetic susceptibility, and geotechnical characteristics. The core interval for sampling was marked by Emmerson geologist during logging, taking into account the contact of mineralization and alteration. Core was cut along a longitudinal line (core axis) and sampled on geological intervals (0.5 m to 1.5 m) as marked and using the pre- designed sample number/cut sheet • MTDD009 & MTDD010 were drilled with PQ3, HQ3 and NQ3 size, sampled on geological intervals cut into half core to provide sample weights of approximately 4.0kg. • Individual DDH core samples are pulverised to produce a 25g charge for analysis by Aqua Regia digestion/ ICP MS & 50g charge Fire Assay/ICP- OES. |

| 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 (e.g., ‘downhole length, true width not known’). |
• Mineralisation identified at the_Mauretania_ Exploration Target is contained within hematite-magnetite-quartz jasper ironstone in the oxidized zone, and intense chlorite alteration with hematite and magnetite stringers in the primary zone see cross – section in the text). • The ironstone dips ~75 degrees to the southwest and strikes NW-SE. Irontstone intersections from current drilling showed a lateral extent of ~150m • Downhole lengths only, true width not known |
| 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. |
• Drilling results are reported at cut-offs as shown in Table 1. |

| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• Refer to body of report. |

| Further work | • The nature and scale of planned further work (e.g., 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 thisinformation isnot commercially sensitive. |
• Geological reinterpretation based on new drilling information • Refer to Figures and text in body of report |
