Weerianna Gold Project Resource Update
Inferred, Shallow Resource of 975Kt @ 2.0 g/t Au for 62,739 contained Oz Au
Artemis Resources Limited (“Artemis” or “the Company”) (ASX:ARV, Frankfurt, US OTC:ARTTF) is pleased to announce the latest resource estimate for the company’s 80% owned Weeriana Gold Project in the West Pilbara region of Western Australia.
The October 2018 resource estimate is classified as Inferred (JORC 2012 Code for reporting Mineral Resources).
Figure 1: Shallow Trenching at Weeriana
Artemis’ Chief Executive Officer Wayne Bramwell commented:
“Artemis has drilled 37,000m across eight of its projects in the last 12 months to best determine which sites warrant more exploration expenditure.
“Weeriana has only been drilled to an average depth of 69m and as a shallow, quartz vein style gold resource may have the potential to increase in scale with deeper drilling.”
WEERIANNA GOLD PROJECT RESOURCE UPDATE
Artemis undertook a reverse circulation (RC) drilling program in 2018 comprising 19 drillholes for a total of 1,644m. Drilling tested for extensions to previously interpreted locations for mineralisation and to provide confirmation of previous results. This announcement provides an updated resource estimate incorporating both the Company’s recent drilling data and drilling data collected during exploration previously undertaken by other companies.
The Weerianna Gold Project (‘Weerianna” or the Project) is located in the West Pilbara region of Western Australia, approximately 25km east of Karratha and 5km west of Roebourne (Figure 2) and is adjacent to the North West Coastal Highway. Weerianna is situated on granted mining lease M47/223 (granted until 27 December 2031). M47/223 is 100% held by Western Metals Pty Ltd, an entity in which Artemis has an 80% interest (via its wholly owned subsidiary, Karratha Metals Pty Ltd). The deposit is 35km by road to the Radio Hill plant where a new gravity gold circuit has recently been installed.

RESOURCE MODELLING AND CLASSIFICATION
The October 2018 Weerianna resource estimate was performed by Mrs Fleur Muller, Director of Geostat Services Pty Ltd (“Geostat”), using Surpac software, utilising historic data and data from the recent RC drilling program completed by Artemis. Mrs Muller has over 22 years of experience in geostatistical resource estimation and meets the requirements for a Competent Person as defined by JORC guidelines.
A classified mineral resource for the Weerianna deposit was calculated by Geostat (as of 27th October 2018) to be 975,700 tonnes at 2 g/t Au for 62,700 ounces (above a cut-off of 1 g/t Au).
Tonnages were applied on a wet basis, as the resource density was derived from gamma density values measured downhole. Diamond density holes will allow the application of a dry tonnage to be applied, resulting in a slight reduction in the total tonnage. Classification of the resource involved several criteria, including drill hole spacing, sampling density, sampling locations, lode geometry, QAQC, bulk density and confidence in grade continuity.
Lodes were classified as Inferred on the basis of the above criteria. A wet density of 2.39t/m3 (oxide), 2.44t/m3 (transitional) and 2.87t/m3 (primary) was used to estimate resource block tonnage for all lodes.
No mining and metallurgical modifying factors have been applied. It is considered that the Mineral Resource may be practically mined by selective open cut mining methods using conventional mining techniques and equipment. It is expected that the various upgrades planned or in progress at the Radio Hill plant allow for processing the Weerianna material. However, no processing test work has been undertaken as yet. The reporting cut-off grade of 1.0g/t Au takes into account these conditions.
The classified Mineral Resource is tabulated in Table 1 as at 27th October 2018 and is reported beneath the topography surface using a 1g/t Au cut-off. Tonnage has dropped by approximately 3% from the previous reported estimate (refer ASX 26 June 2014) as the transitional density of 2.39 for the 2018 resource is lower than that of 2.6 used for the 2009 resource, and this material carries the bulk of the resource tonnage. Another contributing factor is that the recent WERC holes have generally reported lower grades.

DATA INFORMING THE ESTIMATE
Project Geology
The project area mainly comprises rock types belonging to the Roebourne Group of greenstones. Two formations can be distinguished: the basal Ruth Well Formation consisting of ultramafic and mafic volcanic rocks including metabasalt, serpentinised peridotitic komatiite, talc-chlorite schist, grey- and white-banded chert and black chert. Conformably overlying is the dominantly sedimentary unit, the Nickol River Formation. Major rock types include grey- and white-banded chert, ferruginous chert, BIF (Banded Iron Formation), fine-grained clastic sedimentary rocks, quartzite, felsic volcanic rocks, carbonate-rich sediments and also conglomerates (Figure 3).
The rock types present at Weerianna mainly consists of poorly outcropping ultramafic chlorite-serpentinite schists showing variable amounts of silicification and carbonate alteration. Moderately thick to narrow cherty intercalations representing interflow sedimentary rocks are frequently found within the ultramafic schist sequence.
Other lithologies present include BIF and a substantial amount of mainly white quartz veins varying in thickness between 1cm and several metres.
Figure 3: Project Geology and Tenement Plan
Drill holes intersected ultramafic rock types in excess of 80m thick and in several of these holes, wide zones of distinctly spinifex textured ultramafics were found. These schists are found mainly north of a prominent ridge of banded chert which forms the backbone of impressive ridges between Weerianna and Carlow Castle, 7km to the SW. However, ultramafics intercalations are also present within this main chert sequence but these are very poorly outcropping as they are often covered by thick chert scree shedding off the ridges.
Recent investigations by the GSWA found these cherts to be much brecciated and totally silicified mafic cataclastic rocks. These outcrops are associated with shearing and mylonitization along the Regal Thrust. At Weerianna this chert is an almost black, cherty microbreccia that is net-veined by quartz with local gossanous lenses.
The 500m wide zone of ultramafic schists and cherts lies between two relatively competent basaltic terrains. The northern basalt is poorly outcropping but the southern forms substantial hills comprising dark coloured basaltic rock types. These basalts are intruded by gabbroic rocks belonging to the Andover Intrusive Complex which is the largest differentiated Intrusive Complex in the West Pilbara.
Relatively late fresh undeformed micro dolerite intrusions have been intersected in several holes.
The chert-ultramafic sequence at Weerianna represents portions of both the Ruth Well and Nickol River Formation of the Roebourne Group of greenstones. The southern basalt forms part of the Ruth Well Formation. The identity of the northern basalts is not certain, but these are likely to belong to the Regal Formation.
At Weerianna, the dominant structural and lithological trend is north-easterly with a generally moderate to steep south-easterly dip. The schistosity is parallel to the bedding and controls the quartz veining. At places the schistosity and quartz veins are folded.
The depth of weathering as found during drilling varies but is generally around 50 to 60 m in mineralised areas.
Mineralisation
Epigenetic gold (with or without copper) within the West Pilbara is almost invariably associated with shearing and faulting in a variety of geological settings. Favourable settings including sheared units are associated with the Regal Thrust (including Weerianna), splay faulting associated with the Sholl Shear Zone and also around the edges of several mafic/ultramafic intrusions.
At the Weerianna Mining Centre gold mineralisation is associated with quartz veining within chlorite-serpentine schists which have undergone variable degrees of silicification and carbonate alteration. Sulphides including pyrite, arsenopyrite and chalcopyrite are sometimes present in substantial amounts.
The gold deposits are hosted by strongly sheared schists of the Roebourne Group within or immediately beneath the Regal Thrust. The quartz veins generally strike between N and E-NE and the main ore zone dips 70° to the south east.
Other nearby gold prospects within a similar geological setting are found at Carlow Castle, Sing Well, Camper Day and No. Six Well. They are all close to the brecciated chert horizon (Regal Thrust) and are either hosted by schists or are found as small discontinuous quartz veins in basalts. This “gold belt” can be traced for more than 20km.
Drilling
Artemis recently completed an RC drilling program at Weerianna of 19 RC drillholes, totalling 1,644m. Artemis drilling combined with exploration drilling done by previous companies totals 163 RC holes, 3 percussion holes and 5 diamond drillholes for 11,827m. Drill hole depths vary from 30m to 180m, averaging 69m.The hole collar listing for all holes and downhole surveys for Artemis holes can be found in Appendix 1 and Appendix 2.
Sampling and Assay
The majority of samples are derived from RC drilling where 1m downhole samples were collected via a cyclone and passed through either a riffle splitter (historic drilling) or cone splitter (Artemis) to yield a subsample of 2-4kg for assay.
Several assay procedures have been employed with the historic drillholes, which in summary include aqua regia digest followed by AAS of Au followed by fire assay with AAS finish if the gold values were above a defined threshold e.g. 0.5g/t. In addition, when the fire assay exceeded 5g/t another fire assay was done on a split from the original coarse residue.
Samples from Artemis drillholes were assayed for gold by 50g fire assay with AAS finish. Additionally, multi element (33) analyses by 4 acid ICP AES was performed on samples taken by Artemis.
QAQC procedures included, insertion of blanks and reference materials, field duplicate sampling and analysis of historical coarse residue resplits and lab pulp repeats. Geostat’s assessment of 2018 QAQC results for standards was fair, with several values reporting outside the 3SD threshold. The results for blanks indicate the laboratory had acceptable processes in place to minimise sample to sample contamination. Field duplicate results show a fair correlation with a slight bias at higher grades.
Geostat notes that no firm conclusions could be made with respect to historical field duplicates due to differing sample preparation methods. Similarly, for coarse residue analyses the absence of using the same standards and blanks at all three laboratories makes it impossible to draw definite conclusions.
Geological Model
The Weerianna deposit is located within a chert-ultramafic schist sequence, on the overturned eastern limb of an ENE trending syncline. Mineralisation at Weerianna is associated with quartz veins, which are controlled by the schistosity present.
Four distinct mineralisation zones comprise the deposit, with an overall east-west trend and steep dip of approximately -80° towards grid south. 18 wireframes were delineated from sectional outlines to represent all mineralisation within these zones. A combination of assays and lithology were used to define these wireframe envelopes, with a cut-off of approximately 0.5 g/t Au to separate mineralisation from waste.
The wireframed lodes extend over a distance of 600m along-strike, with a maximum down-dip extent of 120m.
Statistics
Log histograms and probability plots of all elements exhibit mixing of populations, likely caused by the presence of both structural and vein related mineralisation. Top-cuts of either 10g/t Au or 20g/t Au were applied to selected lodes in order to constrain extreme values and reduce their impact on estimated grades. Upper inflexion points in probability distribution plots and a high coefficient of variation were used as a guide to determining top-cuts for these wireframes.
Variography
Variography analysis using lognormal variograms was completed on combined composites to supply variogram parameters for grade interpolation. A strike of 090° was interpreted, with a dip of -80° towards 180°. No plunge was detected with the current data levels. A moderate nugget effect is inherent, with 30% of the total variability. Maximum spatial continuity ranges indicate a range of continuity of up to 200m along-strike and 22m down-dip. Downhole variograms are of reasonable quality and indicate a downhole lode width of up to 5m. Quality of down-dip variograms are poor and illustrate the need for infill drilling in this direction.
Block model
A block model of parent cell size 4m (N) x 12.5m (E) x 5m (RL) sub celled to 1m x 6.25m x 2.5m was constructed for the Weerianna deposit. The resource was estimated using ordinary kriging interpolation for all lodes. A minimum of 4 composites and a maximum of 25 composites were used in interpolation of grades into blocks. Search ellipses for initial interpolation of grades comprised 75m x 25m x 10m.
A second subsequent interpolation pass was employed with expanded search ellipses in order to fill blocks in areas of sparse drill density within the lodes. Lodes were classified as Inferred on the basis of drill hole spacing, sampling, lode geometry, bulk density and confidence in grade continuity.
