DRILLING RESULTS - WOLLOGORANG COBALT PROJECT, NT
-
Assays received for 320 of 805 reconnaissance shallow air core drill holes completed this season.
-
Positively 53 of 320 (~17%) of the holes have anomalous cobalt in excess of 100 ppm Co. This compares favourably with the signature of 147ppm Co over the existing Stanton Cobalt Deposit. Deeper drilling on the most prospective targets will commence in two weeks.
-
Shallow drill testing of drill targets to continue for another 2 weeks. Drilling is expected to continue till the commencement of the wet season in November.
-
Measures to overcome recent technical issues with field equipment have been implemented. Over the coming weeks, laboratory assay results from the additional ~500 holes are expected to be released.
Wollogorang Cobalt Drilling Program
Northern Cobalt Limited ( ASX: N27 ) is pleased to announce that ongoing drilling has confirmed significant new cobalt mineralised targets in the results from the first pass drilling campaign. The company has been testing drill targets consisting of magnetic lows similar to that underlying the Stanton Cobalt Deposit. This exploration method has been encouraging, with approximately 17%, or 53 of the 320 drill holes analysed so far intersecting cobalt mineralisation in excess of 100ppm which is comparable to similar samples taken over the Stanton Cobalt Deposit. Deeper follow up drilling to test these targets will commence in two weeks.
“These new drill results are a strong step towards our strategy of adding additional resource tonnes near our existing Stanton Cobalt Deposit ”, Managing Director, Michael Schwarz.

Shallow Drilling Results Defining Deeper Drilling Targets
The highly mobile, 6-wheel drive mounted drill rig is proving very effective at rapidly testing the cobalt potential of our multiple drill targets. The rig is, on average, drilling to a depth of 5 m, allowing us to see beneath the overlying sands and clays which have masked the underlying mineralisation.
To give context to the results we have compared the surface sampling undertaken over the Stanton Cobalt Deposit to get an idea of anomalous values expected in the material over the top of the cobalt mineralisation at depth. The average cobalt of all lag samples taken within the resource boundary is 147 ppm Co with a peak value of 358 ppm Co. Given the shallow nature of drilling on our regional targets we would expect that assay results of 100 ppm and above are anomalous are a good indicator of cobalt mineralisation at depth.

It will take about another 2 weeks to complete the first pass drilling of targets within the immediate vicinity of the Stanton Deposit.

Follow-up Drilling
Northern Cobalt is now refining drill targets that indicate good potential for hosting mineralisation similar to that at the Stanton Cobalt Deposit.
Once the first-pass drilling is complete the drill rig will return to prospects that have demonstrated good cobalt mineralisation. These prospects will be drilled out on a 25m grid, to depths of 30m-40m, to map the dimensions of the mineralised body.
Those prospects that demonstrate the potential to host an economic resource will be drilled out with a large percussion reverse-circulation (RC) rig on 40m centres to a depth of 80m100m.

Appendix 2. The following tables are provided to ensure compliance with the JORC Code (2012) requirements for the reporting of the exploration results for the Wollogorang Cobalt Project
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| 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 down hole 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.

| 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 inthe area. _ |
•Wollogorang Cobalt Project exploration area occurs on EL 31272 which is 100% owned by Mangrove Resources Pty Ltd a wholly owned subsidiary to Northern Cobalt Ltd. •The licence is currently in good standing with the relevant authorities. |
|
| Exploration done by other parties • Acknowledgment and appraisal of exploration by other parties. |
•The Stanton Cobalt Deposit and surrounding prospects were discovered by CRA Exploration Pty Ltd in the period 1990-1996 period under a farm in arrangement with W J (Joe) Fisher. |
|
| Geology • Deposit type, geological setting and style of mineralisation. |
•The local geology is dominated by the Gold Creek Volcanics of the Tawallah Group. This formation is a series of basaltic lavas and shallow intrusives, interlayered with thin oxidised sandstone, carbonate and siltstone units. It is conformably underlain by reduced sedimentary facies of the Wollogorang Formation, which includes dolostones, sandstones and carbonaceous shales. A regional dolerite sill, the Settlement Creek Dolerite, was emplaced synchronous with effusion of the Gold Creek Volcanics. The Wollogorang Formation and Settlement Creek Dolerite do not outcrop on the Stanton prospect area, but are however intersected in a number of drill holes on the tenement. Within the district, the Gold Creek Volcanics are disconformably overlain by a felsic volcanic package that includes a rhyolitic rheoignimbrite sheet (Hobblechain Rhyolite), proximal epiclastics (Pungalina Member) and distal reworked clastics (Echo Sandstone). |

| •Mineralisation is interpreted to be largely controlled by stratigraphy within the flat lying interbedded sediment and volcanic rock units of the Proterozoic Gold Creek Volcanics. Brecciation and faulting has a strong control on the intensity and limits of mineralisation. In fresh rock the cobalt-nickel is located in disseminated siegenite (cobalt-nickel sulphide). Chalcocite and pyrite are also noted. Weathering to a variable depth of approximately 30m has resulted in cobalt oxide secondary mineralisation in a large proportion of the deposit. |

| Drill hole Information • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill holecollar o elevation or RL (Reduced Level –elevation above sea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interceptiondepth o hole length.• If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
•See Appendix 1 | |
| 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 |

| Relationship between mineralisatio n 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 drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not _known’). _ |
•Any observations made are down hole length and true width is 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 drill hole collar locations and _appropriate sectional views. _ |
•See attached release. | |
| 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 significant drill intersections have been reported and it has been noted when no significant intersection has been encountered. |
|
| 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. |
•No other relevant data to report. | |
| 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. |
•Planned further work detailed in this, and previous releases, and in figures. This work includes comprises drill testing further drill targets and follow up drilling of mineralised prospects. |
