recent pressrelease next pressrelease

(businesspress24) -



- Maiden Indicated and Inferred Mineral Resource of 112.4 million tonnes, grading 0.11% cobalt, 0.41% copper and 0.43% zinc, at a cut-off grade of 0.06% cobalt.
- 123,640 tonnes of contained cobalt significantly exceeds the Companys expectation and its previously announced exploration target.
- Mineralised zones comprising the resource are open in all directions, with excellent scope for expansion with further drilling.
- The Mineral Resource will form the basis of the Project Scoping Study for Opuwo, for which key work programs are advancing well, with delivery expected late in Q2, 2018.

Celsius Resources Limited (Celsius or the Company) is very pleased to declare a maiden JORC compliant Mineral Resource at its 95% owned Opuwo Cobalt Project (Project) in Namibia.

The Mineral Resource estimate comprises 112.4 million tonnes at a grade of 0.11% cobalt, 0.41% copper, and 0.43% zinc, at a cutoff grade of 0.06% (or 600 ppm) cobalt. The Mineral Resource estimate represents contained cobalt of 123,640 tonnes and consists of:

- 72.0 million tonnes at a grade of 0.11% cobalt, 0.42% copper and 0.41% zinc in the Indicated category, and a further
- 40.5 million tonnes at a grade of 0.12% cobalt, 0.41% copper and 0.46% zinc in the Inferred category.

The resource has been further split by ore type, as specified in Table 1. Over 95% of the Mineral Resource is comprised of the fresh sulphide ore type, a key feature of the Opuwo Project.

Celsius Managing Director, Brendan Borg commented:

The maiden JORC Mineral Resource for the Opuwo Project meaningfully exceeds the Companys expectations. This is an important milestone that has defined a globally significant potential future cobalt source at Opuwo. The results of the external resource modelling and estimation confirm the consistent and expansive scale of the Project. We are confident that further drilling, which is already underway, will enable future upgrades to the maiden JORC Mineral Resource. The Mineral Resource will underpin our Project Scoping Study, for which key work programs are advancing well.

The Mineral Resource estimate covers a zone of approximately 10 km, with mineralisation remaining open in all directions. Mineralisation, and grade continuity, has already been confirmed over a total of more than 15 km of strike, with over 100 km of total prospective strike identified. The Mineral Resource is considered to have excellent potential for expansion, with further drilling.

Resource modelling and estimation has been completed by independent consultants, DMT Kai Batla.

Summary of Resource Estimate and Reporting Criteria
(for further information please refer to Appendix 2, Sections 1-3)

Geology and Geological Interpretation

Mineralisation at Opuwo is hosted in the Neoproterozoic sediments of the Kaoko Belt, which is interpreted as a western extension of the Copper Belt in the DRC and Zambia. The Dolomite Ore Formation (DOF) is a carbon rich, marly dolomitic horizon in a sequence of clastic and carbonate lithologies in the upper Ombombo Subgroup. The carbon rich nature of the ore bearing horizon is interpreted to have facilitated the precipitation of the metals of interest, namely cobalt, copper and zinc sulphides.

Cobalt, copper and zinc sulphide mineralisation is present predominantly as linnaeite, chalcopyrite and sphalerite respectively. Minor zones of oxidised and partially oxidised mineralisation occur in the upper portion of the deposit.

The lithological logging and grade data obtained from the drillholes reveal excellent continuity along strike, both in terms of geology and grade. The lithological logging and grade values obtained from drillholes drilled in the same section, also reveal excellent continuity, both in terms of geology and grade, down-dip.

The mineralised Dolomite Ore Formation (DOF) was wireframed as a solid, with the aid of drilling, geological logging and grade data. Geological logging and assay data was used to define surfaces to divide the model up into fresh, transition and oxide ore types.

Drilling Techniques and Statistics

The Mineral Resource estimate utilises data from 128 drillholes completed between March, 2017 and December, 2017, covering a zone of approximately 10 km. Twenty-eight (28) holes were drilled using the Diamond Core (DC) drilling technique and one hundred (100) holes were drilled using the Reverse Circulation (RC) method. DC drilling was done using a standard tube, at HQ and NQ size. DC was oriented using a Reflex EZ-TRAC tool.

During the resource definition phase of drilling, all holes were angled at 55 degrees, to attempt to intersect the mineralised unit as close as practicable to perpendicular. A majority of the modelled area was drilled on a nominal 200 metres by 100 metres grid.

All drillholes have been surveyed using Differential GPS, and where possible, holes were surveyed for deviation using a down hole gyroscope. These tasks were undertaken by an external geophysical contractor.
Sampling and Sub-Sampling Techniques

Sampling was undertaken at one metre intervals for Reverse Circulation (RC) drilling and was based on lithology/mineralisation changes for Diamond Core (DC). RC samples were collected from a cone riffle splitter with a three sample chute configuration. Each metre sample was divided into an A (for submission to the laboratory), B (reference sample), and C (large remainder sample). Chips were logged and a small sample of approximately 100g was collected for immediate portable XRF analysis on-site, to assist in determining mineralised zones. The size of the RC samples submitted to the laboratory was typically between 2 and 3 kg.

Diamond Core was sampled according to lithologies, over a length between 20 cm and 100 cm for the NQ or HQ drill core, as half core samples. Diamond Core was cut using a core saw. Generally, half core was submitted to the laboratory, except where a duplicate sample was taken, in which case quarter core was submitted for each of the original and duplicate samples. Field duplicates were collected and analysed to confirm representivity of sampling from both RC and DC drilling.

Sample Analysis Method

Samples were prepared at Activation Laboratories Limited (ACTLABS) Windhoek Laboratory. This preparation consisted of drying, splitting and pulverising. Once prepared, pulp samples were air freighted to ACTLABS in Ancaster, Canada, for digestion and analysis. A 4-acid digestion sample preparation method and ICP-MS/OES finish were utilised. This digestion method acts as a near complete digest for many elements. Samples were routinely assayed for 36 elements, namely Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, Hg, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sr, Te, Ti, Tl, U, V, W, Y, Zn and Zr.

The drilling program included field duplicates, standards and blanks that were inserted into the drill sequence, in addition to the standard QA/QC samples and procedures used by the laboratory. A review of the QA/QC program concluded that the data set was acceptable for the purpose of resource estimation.

Estimation Methodology

GSLIB software was used for the estimation process (Geostatistical Software Library from Stanford University), and all other processes used Datamine Studio 3.0 software. Inverse distance squared was the method used to interpolate grades into a three-dimensional block model.

Directional variography revealed excellent anisotropy along strike for 250 m and good anisotropy down-dip for 250 m. Azimuth and dip anisotropic models were generated in order to account for localised changes in strike direction and orebody dip, respectively.

The mineralised DOF geological wireframe was used to control all the estimates and the block model is contained within this solid. Only composites occurring within the modelled solid were allowed to estimate blocks.

Whilst bivariate statistics were calculated, all metals were estimated individually. A bulk density of 2.9 was used for the fresh and transition ore types, and 2.65 was used for the oxide ore type. Values were determined from routine testing of ore and surrounding zones during the drilling program.

Classification Criteria

The Indicated Mineral Resources were classified based on the modelled variogram ranges, along with an elevation limit of 825 m (equivalent to approximately 425 m below surface). The Inferred Mineral Resource extends 600 m down dip from deepest drillhole intersections, which varies along strike.

All relevant factors have been taken into account for the estimation, and the geological model was reviewed by the site geologists and the Chief Geologist. Sections were generated and submitted to all technical staff for review. The results appropriately reflect the Competent Persons view of the Opuwo deposit.

Cut-off Grade

The cut-off grade of 600 ppm (0.06%) cobalt was selected based on what is currently expected to provide a grade of resource that will be economic to extract. Further, the cut-off grade selected is expected to provide a coherent and mineable body of mineralisation. It is expected that higher grade portions of the deposit can be selectively mined, at higher cut-off grades, if required.

Metallurgical and Mining Factors

Significant metallurgical test work has been completed on mineralisation from the Opuwo Project. Good to excellent recovery of cobalt, copper and zinc sulphides has been demonstrated using conventional flotation techniques. Leach extraction test work on Opuwo sulphide concentrates has demonstrated high leach extractions of approximately 95% for the metals of interest, into a sulfuric acid medium, under relatively low pressure and temperature conditions. All work to date has been completed on fresh, unweathered mineralisation, which is the dominant ore type in the Mineral Resource, with test work currently underway on the minor oxide and transition ore types.

It is anticipated that the deposit can be extracted in part by open pit methods where the mineralised DOF occurs at relatively shallow depths. At deeper elevations, it is expected that the orebody can be extracted by methods such as sub level open stoping, due to the ideal dip of the orebody and the widths of the mineralised zone. A detailed mining study has commenced as part of the Project Scoping Study.

About the Opuwo Cobalt Project

Celsius is aiming to define a long life, reliable source of cobalt at Opuwo. The Company considers the Project to have the following advantages:

· Large scale.
· Favourable mineralogy: cobalt and copper sulphide minerals.
· Low in deleterious elements: notably arsenic, cadmium and uranium.
· Mining friendly, politically stable and safe location with excellent infrastructure.
· Cobalt: best exposure to lithium ion battery boom.

The Opuwo Cobalt Project is located in northwestern Namibia, approximately 800 km by road from the capital, Windhoek, and approximately 750 km from the port at Walvis Bay (Figure 11). The Project has excellent infrastructure, with the regional capital of Opuwo approximately 30 km to the south, where services such as accommodation, fuel, supplies, and an airport and hospital are available. Good quality bitumen roads connect Opuwo to Windhoek and Walvis Bay. The Ruacana hydro power station (320 MW), which supplies the majority of Namibias power, is located nearby, and a 66 kV transmission line passes through the eastern boundary of the Project.

The Opuwo Project consists of four Exclusive Prospecting Licences covering approximately 1,470 km2.
