Artemis Resources boss David Lenigas just tweeted this picture of a heart-shaped gold nugget recovered in the Pilbara region of Western Australia.

“Heart of the Pilbara gold nugget found yesterday,” Mr Lenigas said on Twitter this morning.

The Pilbara region has been undergoing something of a gold nugget rush since last July when Artemis and Canadian partner Novo Resources made a now-legendary announcement regarding a gold nugget find at their Purdy’s Reward site south of Karratha, WA.

Since then a swathe of ASX-listed gold explorers — including De Grey, DGO and Kairos — have converged on the area, pushing up their share prices by double or triple often before a hole has been drilled. (See table below)

Artemis (ASX:ARV) and Novo have been trying to better understand the nuggetty gold phenomenon since they discovered the “watermelon” seed shaped coarse gold nuggets.

Recently Artemis teamed up with the Australian government’s CSIRO science division to investigate the nature of the new style of gold mineralisation.

Here’s a table of ASX-listed Pilbara gold explorers showing how their share prices have fared over 12 months and so far this year:
