Deep Drilling intersects further mineralisation
-
Deep drill hole GODD032 intersects further new zones of copper, pyrite and bismuth mineralisation associated with hematite some 400m below the historic Gecko copper mine
-
This hole provides exciting potential for expanding the already significant 2.7km long Gecko-Goanna-Monitor mineralisation
-
Only 8% of historic drilling in the Tennant Creek Mineral Field has penetrated beyond 150m from the surface. The success of this deep drilling now highlights the depth potential of the field
-
Drilling to commence at the Mulga 1 target this week – part of the 28,000m program approved and funded by partner, Evolution Mining
Emmerson Resources Limited (“Emmerson”, ASX: ERM) is pleased to provide the following update on its first deep drill hole (GODD032) at the Tennant Creek project, which is co-funded as part of the Northern Territory’s “Creating Opportunities for Resources Exploration” (CORE) initiative.
The Gecko-Goanna-Monitor mineral system is the largest in the Tennant Creek Mineral Field (TCMF) (Figure 1), stretching over 2.7km in strike extent and until now, the limiting factor for targeting the deep gold zones under Gecko has been a lack of an effective geophysical technique to guide drilling. A combination of the 2D seismic survey and Emmerson’s new exploration model have been instrumental in the success of this program.
Drill hole GODD032 has intersected further new zones of copper, pyrite and bismuth mineralisation (Table 1) at approximately 400m below the historic Gecko copper mine. The hole has been terminated at a down hole depth of 1,279m - making it the deepest known drill hole in the TCMF(Figures 1 & 2). Representative photos of the various styles of mineralisation intersected are presented in Figures 3, 4, 5 & 6.

This hole has successfully validated Emmerson’s structural interpretation for repetitions of mineralisation at depth. Moreover our exploration model predicts a transition from near surface copper dominant mineralisation to pyrite-hematite-gold-bismuth within the deeper and hotter, fluid conduits of this large mineralising system.
Further work including logging and cutting of the drill core ahead of dispatch for assaying is now underway. Results from this hole will determine the next steps for exploration at Gecko.
Emmerson Managing Director Rob Bills commented: “this deep drill hole is highly significant as it opens up the potential to extend the shallower “Goanna style” copper and also within the deeper dilatant conduits, the possibility for high grade gold-bismuth that was blind to previous explorers. We look forward to receiving the assay results in coming weeks.
The geological implications of this recent drilling go far beyond the Gecko project and provide added confidence for targeting deeper mineralisation across the entire TCMF utilising new concepts and technologies.
The support and co-funding from the Northern Territory Government coupled with the first application of seismic geophysics in the TCMF introduced by our JV Partner, Evolution Mining, was pivotal to the success of this drill hole.
The 28,000m of drilling scheduled for this quarter is underway and will be test a variety of regional greenfield and near mine brownfield targets.”

About Tennant Creek and Emmerson Resources
The Tennant Creek Mineral Field (TCMF) is one of Australia’s highest grade gold and copper fields producing over 5.5 Mozs of gold and 470,000 tonnes of copper from a variety of deposits including Gecko, Orlando, Warrego, White Devil, Chariot and Golden Forty, all of which are within Emmerson Resources (ASX: ERM) exploration and joint venture portfolio. These deposits are considered to be highly valuable exploration targets and, utilising modern exploration techniques, Emmerson has been successful in discovering copper and gold mineralisation at Goanna and Monitor in late 2011, the first discoveries in the TCMF for over a decade. To date, Emmerson has only covered 5.5% of the total tenement package (in area) with these innovative exploration techniques and is confident that, with further exploration, more such discoveries will be made.
Emmerson holds 2,500km[2] of ground in the TCMF, owns the only gold mill in the region and holds a substantial geological database plus extensive infrastructure and equipment. Emmerson has consolidated 95% of the highly prospective TCMF where only 8% of the historical drilling has penetrated below 150m.
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.
Pursuant to the Farm-in agreement entered into with Evolution Mining Limited (Evolution) on 11 June 2014, Evolution is continuing to sole fund exploration expenditure of $15 million over three years to earn a 65% interest (Stage 1 Farm-in) in Emmerson’s tenement holdings in the TCMF. An option to spend a further $10 million minimum, sole funded by Evolution over two years following the Stage 1 Farm-in, would enable Evolution to earn an additional 10% (Stage 2 Farm-in) of the tenement holdings. Evolution must spend a minimum of $7.5 million on exploration, or pay Emmerson the balance in cash, before it can terminate the farm-in. Emmerson is acting as manager during the Stage 1 Farm-in and is receiving a management fee during this period. Exploration expenditure attributable to the Stage 1 Farm-in to date is approximately $5 million.

Section 1: Sampling Techniques and Data – Deep Gecko GODD032 Diamond Drill
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg 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 (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g 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. |
• The Deep Gecko exploration target has not been drill tested before and GODD032 is a proof of concept exploration drill hole. • GODD032 is the first hole drilled into the target. • The RC pre collar (0 – 256m) has been sampled and dispatched to the laboratory. • The RC pre collar chips were riffle split on site to obtain 3m composite samples from which 2.5 – 3.0kg was pulverised (at the laboratory) to produce a 25g charge for analysis by Aqua Regia digestion / ICP- MS/OES (Au,Ag,Bi,Cu,Fe,Pb,Zn). • Individual 1m samples are retained on the drill site. • RC samples were collected via a fixed splitter that is mounted to the drill rig under a 900cfm cyclone. • A reprehensive bottom of hole chip sample was also retained in labelled chip trays for reference and dispatched for ASD analysis in Queensland (Evolution mine site). • Diamond core has been or is in the process of being logged for lithological, structural, geotechnical, density and other attributes. • Sampling was carried out under Emmerson’s procedures and QAQC measures as per industry best practice. • Diamond core is NQ2size, sampled on geological intervals (0.2 m to 1.4 m), cut into half (NQ2) core to provide sample weights of approximately 3.0kg.
