David Lenigas, Artemis’ Executive Chairman, commented;
“We believe that Carlow Castle has the potential to be a significant new Cobalt province in Australia based upon recent exploration results as described below and we are pleased to report the first of what is aimed to be several JORC Code compliant resources on our 100% owned Carlow Castle (Cobalt/Gold/Copper) Project near Karratha. With the world cobalt prices now at US$75,000 a tonne (nearly AUD $100,000 a tonne) and our Quod Est deposit having global resource grades of 0.2% Co or greater the potential economics are very attractive. We expect to complete the next JORC Code compliant resource on the much larger Carlow Castle South deposit by the end of the month and are working hard on all fronts to have Carlow Castle ready and available to provide plant feed for our Radio Hill Plant from July. The latest geochemistry programme, covering 50 km[2] , has also serenpiditiously identified a large number of new high priority Cobalt/Gold/Copper targets ready for drilling. We are already receiving interest from international “Cobalt trading houses” for Artemis’s conflict-free Cobalt.”

Artemis Resources Limited (“ Artemis ”) ( ASX: ARV ) is pleased to provide the first of an anticipated number of JORC Code (2012) compliant resources with the Quod Est deposit at the Carlow Castle (Cobalt/Gold/Copper) Project, located about 20 km southeast of Karratha in the Western Pilbara Region of Western Australia.
Carlow Castle is located only 30 km north-east of Artemis’ Radio Hill processing plant, via gazetted roads. Work has also commenced on converting the portion of Exploration Licence E47/1797 covering the deposits to Mining Leases.
A diamond drilling programme is planned for geotechnical analysis for detailed open pit planning purposes and for advanced metallurgical recovery optimisation and plant operating cost planning.
The Co-Au-Cu mineralisation at Quod Est and Carlow Castle South is hosted in chloritic shear zones within the predominantly Archean mafic sequence. The ore zones appear partially oxidised above 20m with sulphides extending to depth, the primary sulphides are chalcopyrite, cobatite and pyrite; the presence of chalcocite in some samples indicates supergene enrichment in the upper portions of the sulphide zone.
Figure 1: Quod Est and Carlow South areas and geology.
==> picture [462 x 320] intentionally omitted <==
The structural environment of the area is complex; Quod Est strikes north-south and dips steeply to the east (Figure 3) whereas Carlow South strikes east-west and dips steeply to the north. A SAM (Sub Audio Magnetics) geophysical survey is in progress to help resolve the interpretation of the structural system.
JORC Code (2012) compliant resources on the much larger Carlow Castle South deposit are currently being estimated and will be available later this month.
The refurbishment and upgrade works at the Radio Hill Plant are progressing well. The Company is working to have the planned works, including the addition of a 70-100 tonne per hour gravity gold recovery circuit, completed and fully operational by the end of June 2018. The Company is also undertaking studies to increase the overall capacity of the plant to over one million tonnes per annum.
Significant drillhole intersections are listed in Table 1 with a full listing previously contained in ASX announcement 20[th] June 2017 High Grade Cobalt – ‘Four New Targets Identified’.

Co, 0.5% Cu , made up of an Indicated resource of 343,100 tonnes at 1.2 g/t Au, 0.2% Co, 0.5% Cu and an Inferred resource of approximately 214,000 tonnes at 0.6 g/t Au, 0.1% Co, 0.3% Cu.
Considering the potential commercial value of all three elements and the proximity to the Company’s processing plant at Radio Hill and the preliminary metallurgical testwork results previously announced in ASX announcement 19[th] June 2017 “Cobalt Metallurgy Tests Prove Positive Carlow Castle Project”, the project warrants detailed, systematic assessment .

Note : Figures have been rounded and totals may reflect small rounding errors.
The Resource estimate was compiled by Mr. Philip Jones of AM&A using MineMap© software. The mineralisation was digitised on cross sections, snapping to the drill intercepts, using a lower cut-off where the total of Au grams per tonne plus Cu% plus 10*Co% is >0.5. This generic metal content factor was used to define the mineralised envelope because the copper, cobalt and gold are strongly associated with each other and are all potentially economically recoverable.
Sample intervals within the interpreted lode below the designated 0.5 metal content were included within the lode wireframe where in this internal dilution did not drop the total intersection below 0.5 and where it provided improved continuity with other adjacent drill intersections of the lode.
The mineralised zones on each cross-section and long-section were then linked by wireframes to produce “solids” as per Figures 2 and 3. The base of oxidation was triangulated from the drill hole geology logs. Separate wireframes were produced for the Oxide and Primary zones in each of the mineralised shears.
This resource estimate was based on data supplied by Artemis Resources consisting of drill collar coordinates, down-hole surveys, down-hole lithology logs, down-hole density measurements, sample recovery data and assay data. The data was reviewed by AM&A who found the quality of the drilling, sample collection and assays met all the expected industry standards.

A total of 743 density measurements (averaged over 1 m) were collected from 14 of the Artemis drill holes using a downhole gamma/caliper/density/resistivity logger by Downhole Services Group. Of these measurements 52 were in mineralised intervals with >0.5 g/t Au. The average density of the 10 partially-moderately weathered mineralised measurements was 2.65 while the 42 fresh mineralised samples averaged 2.99. Because the less dense, strongly weathered mineralisation near to the surface was not measured due to the spacing of the drill collars, a conservative overall bulk density of 2.5 was used for weathered mineralisation and 3.0 for the fresh ore.

The Indicated and Inferred Resources (Figure 5) extend over a strike length of 220 m with AM&A having classified the reported resources at Quod Est within the portion drilled on a 20 m x 20 m grid down to -50 m RL as Indicated and the remainder as Inferred according to the JORC Code (2012).
Soil Sampling Programme
Subsequent to the Quod Est and Carlow Castle South drilling, Artemis has completed a soil sampling program covering >50 km[2 ] surrounding Carlow Castle and extending through the Sing Well area.
The soil samples were collected at a 15 cm depth within the soil profile on a spacing of 100 m along lines 400 m apart. These were sieved to -2 mm and analysed using the ALS Global partial extraction Ionic leach technique providing low level detection limits and not requiring sample preparation or handling.
The data has been normalised for regolith and lithological variations within the area based on the GSWA 1:100,000 Roebourne mapsheet. Numerous gold, cobalt, copper and palladium targets have been identified, Figures 6, 7, 8 and 9. All data searches have ascertained this area has never been previously geochemically sampled, nor has there been any multi-element data available for the area.
The normalisation process requires the assay value as a ratio to the background, assumed to be the 25[th] percintile of the data, for each individual regolith or geological unit. This results in a value which is unit-less and the results are presented on a percentile basis.

The gold geochemistry indicates strong agreement with structural features from the Roebourne 1:100,000 GSWA mapsheet. The identified anomalism to the north of Carlow Castle is entirely new as the area has undergone extremely limited exploration.
Cobalt shows strong correlation with structural trends, whereas copper shows major anomalies in the Good Luck/Little Fortune Area.

BACKGROUND INFORMATION ON ARTEMIS RESOURCES:
Artemis Resources Limited is a resources exploration and development company with a focus on its prospective Karratha (gold, cobalt, base metals, platinum group elements and iron ore) and the Mt Clement Paulsens (gold) project in Western Australia.
Artemis owns the fully permitted ~500,000 tpa Radio Hill nickel and copper operations and processing plant located 35 km south of Karratha. JORC Code 2004 compliant resources of gold, nickel, copper PGE's and zinc, all situated within a 40 km radius of the Radio Hill plant and on 1,838 km[2] form the newly consolidated assets of Artemis Resources. Artemis is currently refurbishing and upgrading the Radio Hill processing plant and is targeting on having it operational in June 2018.
Artemis have signed Definitive Agreements with Novo Resources Corp. (“Novo”), which is listed on Canada’s TSX Venture Exchange (TSXV:NVO), and pursuant to the Definitive Agreements, Novo has satisfied its expenditure commitment, and earned50% of gold (and other minerals necessarily mined with gold) in conglomerate and/or paleoplacer style mineralization in Artemis’ tenements within 100 km of the City of Karratha, including at Purdy’s Reward (“the Gold Rights”). The Gold Rights do not include (i) gold disclosed in Artemis’ existing (at 18 May 2017) JORC Code compliant Resources and Reserves or (ii) gold which is not within conglomerate and/or paleoplacer style mineralization or (iii) minerals other than gold. Artemis’ Mt Oscar tenement is excluded from the Definitive Agreements.
The Definitive Agreements cover 38 tenements/ enement applications that are 100% owned by Artemis. Pursuant to Novo’s successful earn-in, three 50:50 joint ventures have been formed between Novo’s subsidiary, Karratha Gold Pty Ltd (“Karratha Gold”) and three subsidiaries of Artemis (KML No 2 Pty Ltd, Fox Radio Hill Pty Ltd, and Armada Mining Pty Ltd). The joint ventures are managed as one by Karratha Gold. Artemis and Novo will contribute to further exploration and any mining of the Gold Rights on a 50:50 basis. Further definitive agreements covering approximately 19 Artemis tenements/tenement applications that are already subject to third party interests are expected to be signed once all necessary third-party consents have been obtained
