Artemis are very active in the area and have recently entered in to an earn-in and joint venture agreement with Novo Resources Corp.

Artemis recently raised A$12m for the joint venture with Novo from institutional investors including clients of Sprott Capital Partners.

Artemis Resources has announced the following on the ASX on September 28, 2017:

"Artemis is pleased to announce that an option to acquire up to 80% in two Exploration Licence applications has been signed with Canadian listed Macarthur Minerals.

The tenement applications, E45/4779 (128 km²) and E45/4732 (137 km²), are located 42km west-southwest of Marble Bar and 265km east-south-east of Karratha, in the Pilbara Region of Western Australia.

The tenements have been mapped by the Geological Survey of Western Australia (GSWA) with Mt Roe Basalt covering a significant portion of E45/4779, and also being mapped on E5/4762. The target for the conglomerate gold prospective horizon is below the Mt Roe Basalt.

Artemis will now have 60 days to complete due diligence on the tenements."

A copy of Artemis' full release is available here.

Edward Mead, Artemis' Executive Director, commented; "We have been looking for conglomerate gold prospective projects in the West Pilbara, with the Mt Roe Basalt present, and the potential for conglomerates that sit below the Mt Roe Basalt. The Macarthur Minerals tenements are located covering 265km east-south-east of Karratha, offer a very significant package of highly prospective ground in an area becoming well known for conglomerate hosted gold."

David Taplin, President, CEO and Director of Macarthur Minerals commented; "Macarthur Minerals has significant exploration exposure in the Pilbara Region of Western Australia.We have a sizeable1,514 km² tenement position in the Pilbara that we will now focus on with respect to identifying new conglomerate gold targets. Artemis has extensive experience in this new style of gold mineralisation in the Pilbara and we are pleased to be working with them on this exciting gold play going forward. The Macarthur Minerals tenements have evidence of extensive Mt Roe Basalts across both tenements and the rock sequences under this sequence appear to be the main exploration target in the area. We have a lot of additional tenements in the Pilbara and we look forward to advancing these projects as speedily as possible in our own right."
