N27’s Wollogorang Cobalt Project is a sediment hosted cobalt mineralisation system which has potential for low CAPEX and OPEX options due to:
-
Non-refractory mineralisation (predominantly siegenite - a cobalt sulphide mineral)
-
Cobalt dominant mineralisation occurs from surface
-
Flat lying sediment hosted mineralisation - likely open pit operations
-
Occurs in a supportive first-world mining jurisdiction
THE STANTON COBALT DEPOSIT IS IN THE NORTHERN TERRITORY, AUSTRALIA
NORTHERN COBALT has recognised the growing importance of cobalt sourced from developed world jurisdictions

Regional Significance
-
Fertile hydrothermal system exists beyond the pipes, which are simply a conduit
-
Hydrogeology of overlying package determines how the fluid mixing behaves vertically and laterally
-
Karns Prospect is a phosphatic sandstone 200-300m upsequence where U is dominant
-
This level of stratigraphy is currently untested – can’t yet demonstrate connection to concealed breccia pipe cluster and reductant plume below
-
Permeable conglomerate at base of Pungalina – lateral transport of reductants to promote stratiform mineralisation
-
Part of the broader “Engine Room” for stratiform base metal deposits in Batten Trough (HYC etc)

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. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. •Reverse Circulation (RC) drilling using standard equipment. •Sampling was undertaken at one metre intervals when mineralisation was visually identified and as four metre composites when not. •Drilling was designed to intersect the mineralised ore zone based historical drilling |
| Drilling techniques |
• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). •Reverse circulation percussion (RC) with a 137mm diameter hammer. •Diamond drilling (DD) HQ triple tube. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative •Recovery generally good, with poor recovery in a small number of samples due to groundwater. |
| Criteria | JORC Code explanation Commentary |
|---|---|
| nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
|
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. •Drilling logged in detail on a metre by metre basis. •Lithology, alteration and oxidation logged qualitatively. •Sulphide content and type logged quantitatively and qualitatively. |
| Sub- sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in- situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. •RC drill samples split using a rig mounted cone splitter. •Sample duplicates collected, and standards used to confirm representivity of sampling. •DD samples were cut with an Almonte core saw, halved and quartered and quarter core sent for analysis on a single meter basis |
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of •Sample Preparation - The samples have been sorted and dried. Primary preparation has been by crushing the whole sample. The samples have been split with a riffle splitter to obtain a sub-fraction which has then been pulverised in a vibrating pulveriser. •Analytical Methods - The samples have been analysed by Firing a 40 g (approx) portion of the sample. Lower sample weights may be employed for samples with very high sulphide and metal contents. This is the classical fire assay process and willgive total separation of Gold |
| Criteria | JORC Code explanation Commentary |
|---|---|
| accuracy (ie lack of bias) and precision have been established. Platinum and Palladium in the sample. •Au, Pt, Pd determined by Inductively Coupled Plasma (ICP) Optical Emission Spectrometry. •The sample(s) have been digested and refluxed with a mixture of acids, including Hydrofluoric, Nitric, Hydrochloric and Perchloric Acids. This extended digest approaches a Total digest for many elements, however, some refractory minerals are not completely attacked. •Ca, Cr, Fe, K, Mg, Mn, Na, P, S, V, Co, Cu, Ni and Zn determined by Inductively Coupled Plasma (ICP) Optical Emission Spectrometry. The sample(s) have been digested and refluxed with a mixture of acids including Hydrofluoric, Nitric, Hydrochloric and Perchloric Acids. This extended digest approaches a Total digest for many elements however some refractory minerals are not completely attacked. •Ag, As, Ba, Bi, Cd, Li , Mo, Pb, U, Th •Standards (OREAS 181), blanks and duplicates have all been applied in the QAQC methodology. Sufficient accuracy and precision have been established for the type of mineralisation encountered. |
|
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. •An electronic database containing collars, geological logging and assays is maintained by the Company. |
| Location of data points |
• Accuracy and quality of surveys used to locate drill holes (collar and down- hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. •Holes have been surveyed using Differential GPS (DGPS). •UTM grid MGA94 Zone 53 was used •A majority of holes have had down hole surveys completed. |
| Criteria | JORC Code explanation Commentary |

• Data spacing for reporting of Exploration Results. • Whether the data spacing, and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. •RC drill hole spacing approximately every 20m on a grid across the existing mineral resource. •DD drill holes were drilled at 60 degrees to the south along traverses across the deposit from west to east. •Spacing and distribution is considered to be appropriate. |
| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. •Sample relationship to mineralisation and structure is unknown at this stage. |
| Sample security |
• The measures taken to ensure sample security. •Samples are bagged and sealed on pallets on site and transported to the analytical laboratories by commercial transport companies. |
| Audits or reviews |
• The results of any audits or reviews of sampling techniques and data. •No audits undertaken at this stage as the drilling program has only recently commenced. |
Section 2 Reporting of Exploration Results
(Criteria in this section apply to all succeeding sections.)
| 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. |
•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 largelycontrolled bystratigraphy |

| 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. |
•This information was reported on 5 February 2018 as “Final Drilling Results 2017 Drilling Program”. |
|
| 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 |
•Simple length weighted averages were used for reporting of significant drill intercepts with a cut-off grade of 0.05% (500ppm) Co and a maximum internal dilution of 1m. |
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| _should be clearly stated. _ | ||
| 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. _ |
•This information was reported on 5 February 2018 as “Final Drilling Results 2017 Drilling Program”. •Also 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 along a significant portion of the surface geochemical anomaly. |
