Figure 1 10.4 oz gold bar produced from Titan prospect
Artemis Resources Limited ('Artemis' or the 'Company') (ASX/AIM: ARV) is pleased to report the discovery of exceptionally high grade gold in veins at the Titan prospect as part of its recent ground reconnaissance program at its Karratha Gold Project, in the Pilbara region of Western Australia.
Executive Director George Ventouras commented: "We remain excited by the gold prospectivity that our tenements continue to deliver. The re-focus of exploration efforts and strategy on a tenement wide scale is continuing to deliver evidence of multiple new zones for gold mineralisation, which we believe could contain the potential for large scale deposits. The next steps will allow us to refine these zones, delineate bona-fide prospects and work towards more targeted exploration efforts."

Ground reconnaissance recently completed as a follow up to the previous reported work has delivered further gold occurrences in areas that were previously only lightly explored. This work was designed to map the prospective surface veins and identify additional fertile structures that may contain gold & copper mineralisation. Not only did the ground team identify and trace several large-scale vein trends, they were also successful in identifying a vein zone with abundant coarse visible gold at the Titan prospect.

TITAN PROSPECT
The Titan prospect is essentially a greenfields discovery as previous work conducted at this location was limited to broad spaced soil sampling and a constrained moving loop transient electromagnetic survey (MLTEM) program without any follow up exploration. Titan is located within the Company's Carlow tenement and approximately 2km from the Carlow project where there is a current JORC 2012 compliant Mineral Resource of 374,000oz Au (Au Eq total mineral resource of 704,000 oz AuEq).
Figure 4 Gold bar produced from Titan prospect
Recent work by the Company which focussed on the identification of prospective surface veins has resulted in the discovery of a fertile region around the Titan prospect, including a highly mineralised sub vertical quartz-iron vein zone with abundant visible gold. This work involved taking rock chips from surface and exposing the veining below very shallow cover.
The Titan mineralised trend has been tracked for approximately ~700m and appears to remain open under shallow cover. Furthermore, recent field observations suggest it also occurs on a much larger and strike extensive structural zone.
Multiple hard rock gold samples were extracted from the quartz-iron veining with the largest being an estimated 10cm x 4cm (refer figure 20). Importantly, these gold samples are not analogous to the conglomerate hosted mineralisation, Witwatersrand style of watermelon seed gold nuggets as per the Purdy's Reward and other previously reported discoveries. Instead, these gold occurrences originate from a hard rock source which indicates we are potentially looking at large gold structures, at surface with potential to extend along strike and at depth.
Sampling work was conducted around the Titan prospect with around 300kg material removed. This material was sorted, crushed, separated, gold extracted and a gold bar weighing 10.4 ounces was subsequently produced.
The potential upside remains large not only for this prospect, but more importantly for tenement wide prospectivity as the Company believes Titan is not a sole occurrence but instead part of a larger gold mineralised system across the Carlow tenement.
Further, we believe that the mineralisation extends beyond the Carlow tenement and these trends persist across the Silica Hills and Osborne tenements, leading towards the Lulu Creek prospect which was recently the recipient of a government grant for co-funded drilling.
Rock chips samples from Titan were collected and sent to the ALS laboratory in Perth for analysis. Results received and included the following highlights;
o 24AR11-004, 005, 008 - >10,000 g/t Au*
o 24AR07-002 - 6,520 g/t Au
o 24AR07-169 - 10.2 g/t Au
o 24AR07-192 - 6.1 g/t Au
o 24AR07-162 - 5.1 g/t Au
o 24AR07-184 - 23.8% Cu
o 24AR07-183 - 14.55% Cu
*Note - Rock chip sample processing exceeded the capacity of the lab assay capabilities and resulted in over-limits which are reached when a gold sample records an assay higher than 1% or 10,000ppm Au.

Tenement wide prospectivity
Recent ground reconnaissance programs have been completed with surface samples identifying numerous potential gold mineralisation zones including Carlow, Sing 6-Well and Orpheus. These zones are distinctive trends that have the potential for the discovery of sub-surface gold mineralised zones and have expanded the Company's exploration upside, in a greenfields location, only ~15km from Karratha.

Analysis of gold collected from the surface cover assisted with locating the recently discovered surface veins containing abundant visible coarse gold. These samples were not sent to the lab for assay.

The Carlow project, with its 374,000 oz Au Mineral Resource estimate is an important starting point but the Company is interested in further exploring the prospectivity of the greater tenement package and its inherent mineralisation to identify multiple Carlow type projects or deposits which could be combined with Carlow to form a larger overall system of mineralisation.
This recent program continues to demonstrate the prospectivity of the region and in particular the Artemis tenements and we are confident that further work will result in additional exploration success.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
| Sampling techniques | · 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. | · Samples referred to in this report are obtained from random in-situ rock chip samples collected by Artemis Resources during field reconnaissance exercises. Rock chips containing visible gold has been selectively sampled. Sampling also undertaken across historic workings and mullocks heaps. · The random rock chip samples are irregularly spaced which is considered appropriate for "regional-scale" reconnaissance-level gold exploration. · Rock chips are random, subject to bias and often unrepresentative for the typical widths required for economic consideration. They are by nature difficult to duplicate with any acceptable form of precision or accuracy. · Samples were dispatched to ALS Global Laboratories in Perth for analysis. · Analysis included: - Au-AA26 - Au 50g FA AA finish - Au-GRA22 - default overlimit method - 50g FA with Gravimetric finish; upper limit of the method 10,000ppm; ME-MS6148 element four acid digestion and ICP-MS finish. - Trigger default overlimit method also requested for Ag, Cu, and Zn · Crushing and sluicing equipment was used to produce gold bar from approximately. 300kg of quartz vein material collected from Titan.
