Artemis to attend World Antimony Conference in Guilin, China in early December
Artemis Resources Limited (ASX: ARV) is pleased to provide final drill results from the 15 hole, reverse circulation (RC) drilling programme at the Eastern Hills antimony–lead deposit, located in the Ashburton region of Western Australia (Figure 1). All laboratory assays from the 2,470 metre drill programme have now been received and confirm the presence of significant antimony–lead mineralisation at Eastern Hills.
The latest results have extended the Taipan Zone along strike to the west resulting in a total strike length of 850m (Figure 2), up 40% from the interpreted strike length prior to Artemis’ drill programme. Additionally, results from hole AREHRC013 have doubled the interpreted depth of antimony-lead mineralisation by approximately 90m on that cross section, with an increase in mineralised thickness (Figure 5). Significantly, the Taipan Zone Sb-Pb mineralisation remains open along strike to the east, and also at depth along the 850m of strike extent defined to date.
The final batch of assay results demonstrates additional mineralisation at the western end of the deposit with grades up to 1m @ 5.3% Sb and 7.3% Pb in AREHRC012. All new significant intersections are reported on page 4 (Table 1).

| AERHRC012 | 141m | 145m | 4m | 2.4 | 3.1 | |
| incl. | 141m | 142m | 1m | 5.3 | 7.3 |
Following receipt of all assay results, Artemis has engaged an independent consultant to commence the estimation of a JORC code compliant resource for the Eastern Hills Sb-Pb deposit. Results will be made available publicly in due course.
Artemis General Manager-Exploration, Trevor Woolfe, commented: “We are extremely happy with the success of our Eastern Hills drilling programme in significantly expanding the antimony-lead mineralisation. Before year’s end we expect to be able to quantify this expansion as we announce a maiden JORC compliant resource for the deposit. In a significant step, Artemis will be attending the World Antimony Conference in Guilin, China in early December, as well as visiting Chinese antimony operations.”

EASTERN HILLS Sb-Pb DEPOSIT
==> picture [163 x 245] intentionally omitted <==
The Eastern Hills antimony-lead deposit is located approximately 30km south-southwest of the Paulsens Gold Mine (Figure 1), operated by Northern Star Resources Limited.
At Eastern Hills, Artemis has previously released an exploration target estimate for antimony-lead mineralisation covering the recently re-named Taipan Zone. This exploration target was defined over a 600 metre strike length in what is now thought to be a mineralised system of at least 850 metres in strike length (Figure 2) and which remains open at depth, as well as along strike.
An RC drilling program was completed in October to test the Taipan Zone mineralisation (Figure 2) with the objective of obtaining a maiden JORC compliant resource estimate.

The latest drilling programme was restricted to the Taipan Zone and does not include three additional antimony-lead zones – Dugite and Gwardar (Figure 2) and Tiger – recently identified to the north and northeast of the Taipan Zone[1] . The three new zones have a combined mapped strike length of approximately 2.8 kilometres, and show similar alteration and mineralisation styles to the Taipan Zone and could add significantly to the Eastern Hills resource potential. Encouraging rock chip samples containing up to 5.0% antimony have been collected from these new zones.
TAIPAN ZONE – DRILL PROGRAMME
The 15 hole RC drill programme focussing on the Taipan Zone (previously known as the Main Zone) at Eastern Hills was completed in early October – a total of 2,470 metres were drilled – and details are shown in Table 3.
Laboratory assay results from all holes drilled have now been received and confirm (and in most cases surpass) the antimony-lead readings initially indicated by the on-site hand held XRF equipment. Cross sections displaying interpretations of the mineralisation and significant intervals which are the subject of this most recent announcement are shown in Figures 3-5, while significant intersections are also shown below in Table 1. All intersection lengths are down hole lengths as the interpretations, and hence true widths, are yet to be finalised. Results from the last six drill holes to be reported are described below.
AREHRC006 – Continuation of Taipan Zone mineralisation
Drill hole AREHRC006 successfully intersected the continuation of the Taipan Zone however, represented by a lower grade (<1% Sb) mineralised antimony zone occurring at 120m downhole. This zone is interpreted to continue down dip. It is believed that cross structures have assisted in focussing higher grade Sb-Pb mineralisation in the Eastern Hills deposit. AREHRC006’s lack of proximity to any obvious cross structures may account for the weaker results.
AREHRC007 – Intersects new Dugite Zone near surface, open at depth
This hole was designed to test an electro-magnetic (EM) conductor, termed the “Northern Conductor”, identified in recent remodelling of historical EM data[2] . Geological evaluation of this hole, in conjunction with recent surface mapping, indicates that the mineralisation intersected in the upper 20m of the hole is part of the new Dugite Zone (Figure 2). The Dugite Zone is interpreted to be south dipping and sub-parallel to the Taipan Zone mineralisation, as seen in hole AREHRC014, 130 metres to the south (Figure 3).
AREHRC012 – Hits high grade Sb-Pb zone and extends mineralisation along strike, open at depth
This hole successfully extended mineralisation at the southwestern end of the Taipan Zone (Figure 2). In addition to two lenses of the Taipan Zone being intersected, high grade Sb-Pb mineralisation at depth in this hole is associated with an additional sub-parallel footwall lens (Figure 4) with grades as high as 1m @ 5.3% Sb & 7.3% Pb from 141m intersected. This additional footwall lens appears continuous onto the adjacent section in drill hole AREHRC013. Mineralisation was intersected 150m below surface and is open at depth.
AREHRC013 – Intersects a widening Taipan Zone at depth and an additional footwall zone, both open at depth
Two zones of mineralisation were intersected in this hole confirming the extension of the Taipan Zone and a mineralised footwall zone below historical drill holes EHRC008 and EHRC015 (Figure 5). Results included 2m @ 3.0% Sb & 3.7% Pb from 137m in the Taipan Zone and 1m @ 2.4% Sb & 2.8% Pb from 203m in the footwall zone position. These results extend the Taipan Zone mineralisation 70 metres down dip from the historic hole EHRC008 (Figure 5). Mineralisation is still open at depth.
AREHRC014 – Confirms continuity of the Taipan Zone mineralisation
This hole confirmed the continuity of mineralisation within the central portion of the Taipan Zone. Hole AREHRC014 returned an intersection of 1m @ 3.0% Sb & 3.6% Pb from 59m with mineralisation still open at depth (Figure 3).
AREHRC015 – Pinch out of Taipan Zone mineralisation in structurally complex area, additional potential exists
No significant intersections were returned from the Taipan Zone in this hole, effectively limiting the mineralisation at the western end. However, the drilling intersected a new lower grade (<1% Sb) mineralised antimony zone,

structurally above the Taipan Zone, at 68m downhole. The western end is structurally complex with an interpreted fault offsetting, or restricting, mineralisation to the west. This fault trends northerly towards the adjacent Mt Clement gold deposit, located only 700m to the northwest. Further ground work is scheduled for November to further assess the significance of structural complexity in this area and its relationship to the contrasting mineralisation styles observed at both Eastern Hills and Mt Clement.
The final assay results have advanced the Eastern Hills antimony-lead deposit further to the west, while continuing to extend the mineralisation down dip and confirm its continuity. Drill hole AREHRC007 also provides the first glimpse into the sub-parallel Dugite Zone mineralisation (Figure 2), albeit a low grade intercept close to surface. Significant intercepts from the final batch of drill results are displayed below in Table 1.

FOLLOW UP ON NEW ANTIMONY ZONES
A field campaign at Eastern Hills is scheduled this month to further map and sample the broad area to the north of the Taipan Zone, where three additional zones were recently identified - the Dugite, Gwardar and Tiger Zones. The objective is to delineate new targets (Table 2) for drilling in 2014 and subsequently provide additional antimony resources to the inventory. The complexities of the structural zone between the western end of the Taipan Zone and the Mt Clement gold deposit will also be explored.
