Artemis objective is to upgrade exploration target[1] to a maiden JORC compliant resource
Artemis Resources Limited (ASX: ARV) is pleased to provide further drill results from the latest four holes 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). Drilling has now been completed for a total of 2,470 metres, with laboratory assays from the first nine holes confirming the existence of significant antimony–lead-silver-gold mineralisation. Results for the remaining six holes will be reported in November as they are received.
The current results are from the central portion of the Taipan Zone (previously known as the Main Zone) with the primary aim of extending mineralisation down dip below historic drilling (Figure 2). Significantly, the results from hole AREHRC008 have nearly doubled the interpreted depth of the mineralisation by approximately 100m below historical drill intercepts (Figure 3). Results from drill holes AREHRC009 and AREHRC010 have also successfully extended the mineralisation down dip, in line with our technical team’s modelling.
An increase in antimony grades down dip from the historic mineralisation has been observed, particularly in hole AREHRC010 which intersected the following. All new significant intersections are reported on page 4 (Table 1).
| Drillhole | From | To |

Sb (%) | Pb (%) | Au (g/t) | Ag (g/t) | |
|---|---|---|---|---|---|---|---|---|
| AERHRC010 | 156m | 160m | 4m | 5.3 | 13.8 | 1.66 | 109 | |
| incl. | 159m | 160m | 1m | 10.0 | 30.7 | 3.90 | 185 |
Artemis General Manager-Exploration, Trevor Woolfe, commented: “Following earlier results, we are encouraged by new high grade antimony (up to 10%), lead, silver and gold results at depth in the central area of the Taipan Zone, as well as a 35% uplift in grades in our latest twin hole. The mineralisation displays excellent continuity and our results continue to extend the depth potential of the deposit, which remains open down dip and along strike.”

EASTERN HILLS Sb-Pb DEPOSIT – BACKGROUND
==> 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 estimated and released an exploration target for antimony-lead mineralisation covering the recently re-named Taipan Zone1. This exploration target was defined over a 600 metre strike length in what is now thought to be, based on an EM conductor (the Southern Conductor) and the current drill programme, a mineralised system of at least 1 kilometre in strike length (Figure 2) and which is considered to be open at depth, as well as along strike.
An RC drilling program was designed to test the Eastern Hills geology with the objective of obtaining a maiden JORC compliant resource estimate.

==> picture [226 x 66] intentionally omitted <==
The current drilling programme is restricted to the Taipan Zone (Figure 2) and does not include three recently identified additional antimony-lead zones (Dugite, Gwardar and Tiger) directly north and northeast of the Taipan Zone[2] . These 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.
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 the first nine holes drilled have now been received and confirm (and in most cases surpass) the antimony-lead levels initially indicated by the on site hand held XRF equipment. Cross sections displaying interpretations of the mineralisation and significant grades 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. Latest results from the following four drill holes described below, reflect increasing grades towards the central portion of the Taipan Zone.
AREHRC008 – Extends mineralisation 110m down dip, open at depth
Significantly, drill hole AREHRC008 extends the Taipan mineralised zone for a further 110m down dip below the historical drill hole EHRC005, to a vertical depth of 220m below surface. This almost doubling of the depth of the Taipan Zone mineralisation is further enhanced by the improved grade and width of mineralisation, with a zone of 8m @ 2.0% Sb and 2.6% Pb intersected (Figure 3). A lower grade (<1% Sb) mineralised antimony zone defined by a 0.1% Sb lower cutoff in the hanging wall in holes EHRC004 and EHRC005 is also interpreted to continue down dip into the hanging wall zone of AREHRC008 (Figure 3). Mineralisation is still open at depth.
AREHRC009 – Extends Taipan Zone mineralisation 60m down dip, open at depth
As per hole AREHRC008, drill hole AREHRC009 was designed to test the down dip extension of the known mineralisation encountered in historical holes EHRC016 and EHRC017 (Figure 4). The intercept of 3m at 2.1% Sb and 2.5% Pb from 159m down hole (Table 1) confirms the continuity and antimony grades indicated from the two historical holes, and extends the mineralisation 60m down dip . Encouragingly, another mineralised zone (<1% Sb) was intersected in the hanging wall immediately above the Taipan Zone (Figure 4). This may represent another antimony zone developing at depth and correlate with the lower grade zone on the adjacent section (Figure 3). Mineralisation is still open at depth.
AREHRC010 – Hits high grade Sb-Pb-Ag-Au zone and extends mineralisation 65m down dip, open at depth
This hole was designed to test the down dip potential for mineralisation below historical hole EHRC013 (Figure 5). A substantial increase in the antimony grade down dip from the historic mineralisation was observed in this hole which intersected 4m @ 5.3% Sb, 13.8% Pb, 1.66g/t Au and 109g/t Ag from 156m, including 1m @ 10.0% Sb, 30.7% Pb, 3.90g/t Au and 185g/t Ag from 159m. These are the highest grade results for antimony, lead, gold and silver intersected in the Artemis drilling to date. This zone is interpreted to extend the Taipan Zone of mineralisation 65 metres down dip from the historic hole EHRC013 (Figure 5). Mineralisation is still open at depth.
AREHRC011 – Successful twin of historical drill hole, grades improved by over 35%
For quality assurance purposes Artemis drilled hole AREHRC011 to twin historical hole EHRC013. The Artemis hole successfully confirmed the mineralised zone initially encountered in EHRC013. However, the current assay results of 3m @ 3.6% Sb and 6.6% Pb from 83m, including 1m @ 6.9% Sb and 8.9% Pb from 83m (Figure 5), show a significant increase (38% for Sb and 35% for Pb) in grade over the previous historical assays from hole EHRC013 which intersected 3m @ 2.6% Sb and 4.9% Pb from 84m.
2 As per ASX announcement dated 26 September 2013 “New Antimony Zones Identified at Eastern Hills”

==> picture [226 x 66] intentionally omitted <==
The latest assay results confirm that the model for the antimony-lead mineralisation identified at Eastern Hills, as vein hosted massive sulphides bounded by a broader zone of disseminated sulphides, has been validated and confirms Artemis’ objective of extending the Eastern Hills antimony-lead mineralisation both along strike[3] and down dip from the current phase of drilling. Assay results from the remaining 6 holes from this current drilling programme are anticipated over the coming 3-4 weeks (Table 2) with the objective of completing a maiden JORC compliant resource by year end.
