UPDATE 2.55pm: Shares in Thundelarra soared after the explorer released more promising drilling results from its Red Bore project near Meekatharra.

The company said it had encountered copper mineralisation in four of six holes drilled recently.

The best intercept was 0.65 metres at 36.04 per cent.

Thundelarra said two immediate drill targets had been identified following the recent drilling program.

"The new interpretation has increased the prospectivity of the Red Bore project area by opening up the possibility that we have an intrusive-related system preserved in its entirety," the company said in a statement.

Thundelarra shares closed up 2.4 cents, or 34.29 per cent, at 9.4 cents after touching an earlier high of 11 cents.
