35.7% Sb - HIGHEST ANTIMONY RESULT TO DATE AT EASTERN HILLS New Dugite Zone grades overshadow Taipan Zone EASTERN HILLS ANTIMONY-LEAD (Sb - Pb) DEPOSIT New zone at Eastern Hills reveals highest antimony grade to date Dugite Zone rock chip sample returns 35.7% Sb, 29.0% Pb, 1,335g/t Ag & 0.56g/t Au Significant gold mineralisation also identified – up to 3.36g/t Au in Dugite Zone rock chip sample Historic rock chip results up to 33.0% Sb, 36.0% Pb, 1,500g/t Ag & 6.80g/t Au also on Dugite Zone Reinforces potential of new zones to add to Taipan Zone metal inventory Follow-up field campaign in November to close off 2013 field season JORC code compliant resource estimation of Taipan Zone mineralisation is underway
Artemis Resources Limited (ASX: ARV) is pleased to announce that high grade assay results have been received from follow-up geological mapping and sampling of antimony-lead mineralisation zones identified in close proximity to the Taipan Zone at Eastern Hills (Figure 1), located in the Ashburton region of Western Australia (Figure 4). While the Taipan Zone was the focus of Artemis’ recent drilling programme and current JORC resource study, the Company 1 announced in September that it had identified three additional zones of similar style mineralisation that appear to be part of a more widespread mineralised system – the Dugite, Gwardar and Tiger Zones. The latest rock chip sampling results from the Dugite Zone, located just north of the Taipan Zone, have returned the highest antimony grade seen to date at the Eastern Hills Project of 35.7% Sb. The same sample, collected from the eastern portion of the Dugite Zone (Figures 1 & 2), also included extremely high grades of 29.0% Pb, 1,335g/t silver (Ag) & 0.56g/t gold (Au). Further significant results from the Company’s October rock chip sampling of the new zones included: 5.4% Sb, 9.2% Pb, 277g/t Ag & 1.53g/t Au (Dugite Zone) 1.1% Sb, 3.9% Pb, 44g/t Ag & 3.36g/t Au (Dugite Zone) 3.8% Sb, 11.7% Pb, 50g/t Ag & 0.24g/t Au (Tiger Zone) These results elevate the Dugite Zone to become a key focus in the Company’s quest for additional resources to add to the mineralisation recently drilled at the Taipan Zone. This is reinforced by Artemis’ recent re-evaluation of previously unseen historical data which revealed rock chip sampling results of up to 33.0% Sb, 36.0% Pb, 1,500g/t Ag & 6.80g/t Au in the vicinity of the Dugite Zone high grade results described above (Figure 2). Artemis will undertake another detailed mapping and sampling campaign of the Dugite, Gwardar and Tiger Zones over the coming weeks, before the end of the field season. Artemis General Manager-Exploration, Trevor Woolfe, commented: “Our exceptionally high grade rock chip results from the Dugite Zone that correlate with equally exceptional historical sampling results highlight the new zone’s antimony-lead-silver-gold potential in addition to that already outlined at the Taipan Zone. The high grades at Dugite are significantly higher than any of the surface sampling results recorded on the Taipan Zone.”

EASTERN HILLS Sb-Pb – A MULTIPLE VEIN SYSTEM CONFIRMED 2
In January 2013, Artemis announced an exploration target at Eastern Hills. This target was based on antimony-lead mineralisation identified by historical exploration on a singular massive sulphide vein (now known as the Taipan Zone) over a strike length of at least 600m. Identification of three new zones (Dugite, Gwardar and Tiger), as well as 1 extensions to the Taipan Zone, through mapping and sampling in September , increased the potentially mineralised combined strike length of all four zones by 350% to 2.8km. Quartz-sericite alteration and silicification along fault structures identified at Dugite, Gwardar and Tiger corresponds with similar mineralised alteration on the Taipan Zone and indicates that the Eastern Hills system is not a lone vein, but a multiple vein system. The latest round of rock chip sampling, consisting of 15 samples, was undertaken during breaks in the recent Taipan Zone drilling programme. Sampling was focussed on the Dugite and Tiger Zones in response to positive results received from our initial mapping programme in September where results of up to 2.9% Sb (Dugite Zone) and 5.0% Sb (Tiger 1 Zone) were obtained . 2
Exploration target reported in ASX Announcements dated 16 and 18 January 2013

For personal use only
Significant results from the latest rock chip sampling (Table 1) provide further evidence that Eastern Hills is shaping up to be a significantly mineralised multi-vein system predominantly containing antimony-lead with locally rich precious metals. In addition to the exceptional antimony and lead results (35.7% and 29% respectively), silver up to 1,335g/t (or 43oz/t) and 3.36g/t gold have been obtained on the Dugite Zone (Table 1). The Tiger Zone also reported significant results up to 3.8% Sb.

Taipan Zone Drilling from the Company’s recently completed 15 hole reverse circulation (2,470 metre) programme along the Taipan Zone (Figure 1) has confirmed the excellent potential for this zone with the deposit extended to at least 850m strike 5 length, and it remains open to the east and down-dip . Artemis has now commenced a JORC code compliant resource estimation on the Taipan Zone. Dugite Zone The Dugite Zone lies immediately to the north of the Taipan Zone (Figure 1). This zone currently has a mapped strike length of approximately 1.1km and is striking east-northeast. As mentioned above, further encouragement was obtained from the latest rock chip sampling campaign with one particularly high grade result (sample 238639 - Table 1). Artemis recently uncovered, and reviewed, historical rock chip sampling results along the Dugite Zone. Significant historical results (Sb>1%) are provided in Table 2 and are displayed on Figure 2. The results provide further support that the eastern end of the Dugite Zone is highly prospective for exceptionally high grade antimony, lead, silver and gold. Results of the historical sampling returned up to 33.0% Sb, 36.0% Pb, 1,500g/t Ag & 6.80g/t Au within a 50m zone of Artemis’ recent high grade antimony result (sample 238639), all of which were taken from the eastern end of the Dugite Zone. More detail of the results from both phases of sampling can be seen in Figure 2 which clearly shows high grade zones associated with two northwest-southeast trending interpreted fault zones cross-cutting the Dugite Zone. The two cross-cutting structures, which also appear to cut the eastern end of the Taipan Zone, are interpreted to have provided a pathway for mineralising fluids.

Figure 2: Dugite Zone (East) – Artemis & Historic Sampling Results and Mapping (refer Fig 1)
The recent and historical sampling results have defined not only significant base metal (Sb & Pb) mineralisation but also significant zones of precious metal (gold and silver) mineralisation at numerous points along the Dugite Zone (Figure 3). Dugite Zone precious metal results include (see Tables 1 and 2): 220g/t Ag & 6.80g/t Au (EHG057 - historic result) 110g/t Ag & 6.40g/t Au (EHG001 - historic result) 200g/t Ag & 3.90g/t Au (EHG002 - historic result) 44g/t Ag & 3.36g/t Au (238638 - Artemis result) 1,500g/t Ag & 0.50g/t Au (EHG141 - historic result) 1,335g/t Ag & 0.56g/t Au (238639 - Artemis result) Mineralisation at the eastern end of the Dugite Zone is interpreted to be the result of a northwest-southeast fault zone cross-cutting the Dugite silica alteration zone roughly perpendicular to the strike of that zone. It would appear that this later stage cross-cutting fault zone provides the fluid pathway for the antimony-lead-silver-gold mineralisation seen at the Eastern Hills deposit. This model provides encouragement for further discoveries of mineralisation on both the Gwardar and Tiger Zones, which at this point have not been mapped or sampled to the same level of detail as the Dugite Zone.

Tiger Zone The Tiger Zone is located 500 metres to the northeast of the Taipan Zone (Figure 1) and returned a high grade result of 5.0% Sb from the recent September 2013 sampling programme. Follow-up work during October detailed further encouraging mineralisation with 3.8% Sb and 1.6% Sb results obtained from this latest campaign (Table 1). The Tiger Zone has a northeast orientation which, although different from the more central alteration zones, still shows evidence of a pathway for mineralisation along the fault structure. The Tiger Zone, with only limited mapping and sampling by Artemis to date (8 samples), will be a focus for follow-up mapping and rock chip sampling this month. Gwardar Zone 1 The Gwardar Zone was recently identified and lies to the north of the Dugite Zone (Figure 1) with an approximate strike length of 700m. No further mapping or sampling of this zone was undertaken during the recent sampling programme. To date only one rock chip sample has been taken by Artemis from the Gwardar Zone and an encouraging result of 0.4g/t Au was recorded. A gold result of this level is encouraging as it suggests a potential link between the nearby Mt Clement gold deposit and the western end of the Eastern Hills mineralisation. More systematic mapping and sampling of the Gwardar Zone is currently being planned. November Field Campaign Following the encouragement of reconnaissance mapping and sampling to date, the Dugite, Gwardar and Tiger zones will now be subjected to a more detailed mapping and rock chip sampling programme with the objective of defining further targets outside of the Taipan Zone for drill testing to be undertaken in the 2014 field season. This campaign will be undertaken in November prior to the onset of the wet season, with results expected in the New Year.

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. 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, facesampling bit or other type, whether core is oriented and if so, by what method, etc). Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative 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.
A rock chip sampling technique testing specific geological targets was used to obtain a 0.5-1.5kg sample for submission to the laboratory for ICP and XRF analysis. No field duplicates or blanks were submitted for analysis.

Sample security
The measures taken to ensure sample security.
All geological mapping and sampling information is completed firstly on to paper maps and survey books before being transferred to Microsoft Excel spreadsheets. All electronic field data is then transferred into a Microsoft Access database for validation and compilation. Physical maps and sampling data are returned to the Artemis head office for scanning and storage. Electronic copies of all information are backed up daily. No adjustments of assay data are considered necessary. A Garmin GPSMap62 hand-held GPS is used to define the location of the rock chip sample locations. Standard practice is for the GPS to track the location of the user constantly and the location of the rock chip samples are recorded electronically as ‘waypoints’ at the time of sampling. Sample locations are considered to be accurate to within 5m. Grid system used for Artemis Resources Ltd sampling is MGA 94 (Zone 50) Topographic control is obtained from surface profiles created by close spaced historical aeromagnetic survey data and calibrated with GPS surface measurements. It will be necessary to undertake more detailed topographic controls later in the program. Historical (Taipan Resources NL) locations were obtained by a handheld GPS using the AMG66 coordinate system. Artemis has converted these locations to MGA94 using mining software (Mapinfo coordinate converter) before validating the data for storage in an Access database. Rock chip sampling has been completed on specific geological targets during geological mapping activities. Data from rock chips will not be used in resource and reserve estimations. Sampling is based on specific geological targets to understand geochemical distribution. No sample compositing is used in this report. Most rock chip samples have been obtained whilst conducting reconnaissance geological mapping which was seeking to identify mineralised structures/lodes. As the sampling was targeting specific lithologies, to understand the distribution of geochemistry within different rock types and alteration types, there may be some bias in these samples.

Relationship between mineralisation widths and intercept lengths
JORC Code explanation
Commentary remains open along strike to the east and at depth. Mineralisation occurs as massive sulphides bounded by a broader zone of disseminated sulphides. Sulphide mineralogy consists of pyrite, boulangerite – a lead-antimony sulphide – and arsenopyrite with minor pyrrhotite, chalcopyrite and galena. The reconnaissance mapping that is the subject of this report has confirmed three new alteration zones (named Dugite, Gwardar & Tiger) which, given the currently available information, appear to be analogies of the Eastern Hills antimonylead deposit geology (termed the ‘Taipan’ Zone).
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 hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth 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.
Not applicable.
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 should be clearly stated.
A lower cut-off grade of 1% Sb and/or 0.2 g/t Au have been used for assessing significant intercepts, and no upper cut-off grade was applied. No metal equivalents are used for reporting.
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

JORC Code explanation are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).
Commentary
Diagrams
Appropriate maps and sections are available in the body of this ASX announcement.
Balanced reporting
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. 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.
Reporting of results in this report is considered balanced.
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 significant exploration work has been done by Artemis.
Further work
The nature and scale of planned further work (eg tests for lateral extensions, 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.
Artemis has plans in place to follow-up this reconnaissance mapping and sampling with more detailed mapping during November 2013. Results from this work will be announced when available.
