ASX Announcement 11 February 2019

  • Objective of programme was to determine amenability of Carlow Castle Au-Cu-Co Project to conventional gravity, leach and flotation processes 
  • Results confirm effective separation and high recoveries of Gold, Copper and Cobalt via conventional process routes 
  • Preliminary test work on two composite samples indicates: 
  • Total recovered gold of 98-99% - with significant coarse, gravity recoverable gold up to 48% 
  • Total recovered copper of 77-85% - with flotation producing premium grade concentrates of ≈30% Cu 
  • Total recovered cobalt of 73-79% - with flotation producing concentrates of 2.3 – 5.3% Co 
  • Gold not recovered via flotation amenable to cyanide leach process 
  • Results provide a strong basis for further flowsheet optimisation and geometallurgical test work

Artemis Resources Limited (“Artemis” or “the Company”) (ASX:ARV, Frankfurt: ATY, US OTCQB: ARTTF) is pleased to provide this metallurgical update on the company’s Carlow Castle Au-Cu-Co Project in the Pilbara region of Western Australia.

Laboratory scale gravity gold, cyanide leach and flotation processes were adopted with a view to gain an insight into the metallurgical behaviour and recoverability of gold, copper and cobalt. Two drill hole composites were generated and tested at ALS Metallurgy in Western Australia. Table 1 summarises metallurgical results from optimised tests from a 50- test suite.

Table 1: Carlow Castle Au-Cu-Co Project – Summary of Optimised Results 

Artemis Chief Executive Officer Wayne Bramwell commented; 

“Artemis is encouraged by the amenability of the deposit to conventional processing options and the excellent recoveries of the three key minerals. Gold and high-grade copper concentrates will be the primary value drivers at Carlow Castle with cobalt representing a third and valuable product stream that should appeal to many potential off-take partners.”


Artemis has completed preliminary metallurgical test work on the Carlow Castle Au-Cu-Co Project at ALS Metallurgy in Western Australia. The programme focussed on metallurgical amenability on selected samples from the Carlow Castle deposit employing conventional gravity gold, cyanide leach and flotation processes. Outcomes specific to the metallurgical response and recovery for three target commodities (gold, copper and cobalt) are proposed to be used for further project development evaluations.

Sample Selection 

Two 100 kg HQ diamond core metallurgical composites, sampled from drill holes CCAD001 to CCAD012 (refer ASX release 15 October 2018 and Figure 1), were used for this programme.

ASX Announcement 31 January 2019 

Artemis Resources Limited (“Artemis” or “the Company”) (ASX:ARV, Frankfurt: ATY, US OTCQB: ARTTF) is pleased to provide this update on activities for the quarter ended 31 December 2018, and significant events post the reporting period.

Artemis’ Executive Chairman David Lenigas commented: 

“This has been a massive quarter with the company’s exploration team successfully defining eight (8) new exploration targets at the Armada Prospect in the Paterson Ranges, delivering three (3) resource updates across our gold and base metal assets and announcing three (3) new gold discoveries in the West Pilbara. 

With respect to the restart of Radio Hill, resource definition and geo-metallurgical programmes remain the key determinants of the timing to production. To underpin commencement of operations, Artemis is working towards defining at least 3 years of plant feed from within the company’s extensive gold and base metal assets or equivalent tonnages of gold ore from third-parties or joint ventures. 

As such it is prudent to concurrently advance resource development and geo-metallurgical studies on Carlow Castle Au-Cu-Co and Whundo Cu-Zn Projects and evaluate third-party gold ore toll treatment options prior to completion of the Radio Hill refurbishment.” 

Highlights to 30 January 2019 include: 

  • Eight new exploration targets defined in the Paterson Province 
  • Shallow Nickel-Copper resource defined at Radio Hill
    Resource Update for Weeriana Gold Project 
  • Drilling recommences at Carlow Castle Gold-Copper-Cobalt Project 
  • Overseas Institutional Funding for Patersons Range 
  • Artemis commences trading on U.S. OTCQB exchange 
  • Three new Gold discoveries in the West Pilbara
  • Metallurgical Update for the Carlow Castle Gold-Copper-Cobalt Project 
  • New Cobalt targets defined in the West Pilbara 
  • Artemis and Pacton Sign Strategic Processing alliance 
  • Resource Update for Whundo Copper-Zinc Project


The December quarter saw the culmination of the 2018 exploration and drilling programmes undertaken by Artemis across its suite of West Australian gold, base and battery metal assets. The company’s resource inventory continues to grow with three resource updates released to the market. A new resource update for the Carlow Castle Au-Cu-Co Project is now expected for release in February 2019, post final internal review. 

Exploration success has defined three new gold discoveries within 30km of the Radio Hill process plant. New targets at Patterson’s Hut, Ruth Well North and Pipeline show strong gold grades from surface rock chip sampling up to 11.4g/t Au and pending access agreements will be advanced in 2019. 

Concurrently Artemis has moved rapidly on its newly acquired Pilbara exploration licence application over ≈600km2 in the Paterson Ranges with the first magnetic survey flown by the company identifying eight (8) new targets to the north and south of the Havieron Prospect (refer Figure 1). Artemis expects this tenement to granted in Quarter 1, 2019.

ASX Announcement 21 December 2018 

Indicated JORC resource of 1.15 Mt @ 0.52% Ni, 0.73% Cu and 277ppm Co for 5,980 t contained Nickel, 8,395 t contained Copper and 318 t contained Cobalt

Artemis Resources Limited (“Artemis” or “the Company”) (ASX:ARV, Frankfurt:ATY, US OTC:ARTTF) is pleased to announce a new, shallow JORC 2012 resource estimate for the company’s 100% owned Radio Hill Nickel Mine in the West Pilbara region of Western Australia. The December 2018 resource estimate is classified to JORC 2012 compliant Indicated category. 

Figure 1: Radio Hill Mine area, Processing Plant and resource drilling location. Artemis’ Executive Director Ed Mead commented: 

“This updip extension to the historic Radio Hill underground represents a new, shallow nickel – copper resource approximately 400m from the Radio Hill plant.

Further resource development work isrequired to determine the optimum means to monetise the project and this work will be reviewed in 2019.” 


The Radio Hill Nickel Mine is in the West Pilbara region of Western Australia, ≈35 km by road south of the city of Karratha (Figure 2). Access is via the Karratha - Tom Price sealed road and then mine access tracks. Radio Hill is on a fully approved mining lease and contains Artemis’ 100% owned Radio Hill Processing Plant and the historic Radio Hill underground mine. The underground mine ore was processed through Radio Hill prior to the plant being placed into care and maintenance in September 2008 due to low commodity prices.

Drilling by previous operators of Radio Hill comprised 1,052 drill holes including open hole percussion, RAB, RC, underground sludge and diamond drilling for a total of approximately 89,885 metres. In 2018 Artemis drilled the shallow mineralisation up-dip from the Fox underground workings on a regular grid. This included another 80 Reverse Circulation (“RC”) drill holes and 7 diamond drill holes for an additional 6,779.5 metres, aiming to verify older drilling and to increase the drill data available in the upper levels of the mineralisation.

Figure 2: Radio Hill Location Map 

This drilling, sampling and assaying has been verified by Al Maynard & Associates (AM&A) as complying with the JORC Code (2012) for reporting exploration results and Mineral Resources. AM&A used the Artemis drilling only to model the shallow resources, ignoring the earlier drilling as it could not be verified as conforming to the JORC Code (2012). 

These Indicated resources, as estimated by AM&A are 1.15 million tonnes at 0.52% Ni, 277ppm Co and 0.73% Cu. 

Cobalt is a potential by-product that may report to the Ni concentrate and so is included in the resource estimate.
