Cassowary Tenement Granted Holdings Expanded

Cassowary Project - Key Cassowary Tenement Granted Holdings Expanded to cover additional Copper-Gold Targets

Highlights

·      Exploration Licence E69/4266 (341km²) covering the large Cassowary Intrusion[1]  granted on 11 August.  Geophysical surveys and drilling planned to start in December Qtr

·      Four magnetic and structural targets (T1-T4) identified within E69/4266. The Cassowary Intrusion (T1) is the first priority for drilling

·      Targets exhibit geophysical features with similarities to IOCG type and other intrusion-related copper and gold deposits such as Ernest Henry, Carrapateena and Havieron

·      E69/4266 covers northern part of interpreted 30-40km wide rift zone bounded by the Madura Crustal Boundary to the west and an un-named geological domain to the east

·      Further application made for a large exploration licence (EL69/4330 for 447km²) to cover additional interpreted intrusions in the southern part of the rift zone[2]

·      Negotiated terms for an access agreement with the Pila Nguru Aboriginal Corporation with agreement expected to be executed at an upcoming meeting  

·      Artemis well funded to conduct geophysical surveys and initial drilling program at Cassowary following recent $4.75m placement announced 21 July

·      Also on track for a September start to RC drilling at Titan Prospect near the Carlow gold/copper resource[3] in the north Pilbara, followed by drilling for extensions to Carlow

Artemis Resources Limited (ASX/AIM: ARV) ("Artemis" or "the Company") is pleased to advise that Exploration Licence E69/4266 covering the large, interpreted Cassowary Intrusion and three adjacent targets has been granted.  Cassowary is 440km east of Kalgoorlie and accessable via the Trans rail line road, the Connie Sue 'Highway' and station tracks. (Refer Figure 1)

Project Background

The Cassowary Project covers several undrilled interpreted intrusions within a 30-40km wide, previously undocumented, interpreted rift zone - below an estimated 250-300m of consolidated Eucla Basin sediments comprising limestone, sandstone and shale. (Refer Figure 2)

The estimated thickness of the Eucla Basin sequence is based on 13 historic holes drilled across the region which have an average depth of 239m to the Proterozoic basement. The interpreted rift zone is expected to include metamorphosed sediments, mafic volcanic units and intrusions based on sparse drilling across the Madura Province and available geophysical data[4].

The interpreted intrusions may be related to rift margins and cross cutting structures. The Company recently increased its tenement area to around 990km² to cover additional targets within the interpreted rift zone, south of two applications by WA1 Resources Limited (WA1)[5].

Cassowary Intrusion

The interpreted Cassowary Intrusion is the highest priority target (T1) on E69/4266 with drilling likely to follow a detailed gravity survey to assist drill targeting.  The Cassowary Intrusion[6]:

Ø has a large magnetic footprint (5-10kms in width)

Ø is located on the contact of the Madura Crustal Boundary

Ø coincides with a cross-cutting NW-SE trending, 3-4km wide interpreted fault zone

Ø interpreted to have disrupted surrounding magnetic units by >20kms

Ø may represent a long-lived focus for magmatic activity

Ø may also represent a possible conduit for hydrothermal fluids  

Julian Hanna, Managing Director, commented:

"I am happy to report the Artemis team is very excited to have the Cassowary tenement granted which should enable field activities to get underway soon. The 7-month application period has been put to good use by Artemis Chief Geologist, Oliver Hirst.  Oliver has made excellent progress in building our understanding of the unique potential of this area which we think has been overlooked by previous explorers and majors who have held tenements in the region. 

Only two holes (BKD 1 and BKD 2) are recorded as having been drilled within the area shown in Figure 2.  Both holes were drilled by Gunson Resources in 2009, with both reporting elevated copper in a Proterozoic mafic intrusion, 25km south-east of Cassowary.

The Cassowary Intrusion is a rare opportunity to explore the potential for large-scale IOCG type Copper/Gold deposits and other deposit types including Nickel/Copper/PGE (mafic intrusion type) and Gold (hydrothermal vein systems) in an area with effectively no prior drilling. 

We look forward to reporting progress at Cassowary in the lead up to the initial drilling program and the team at Artemis is working hard to get drilling underway as soon as possible".
