Nimy announced on Wednesday it had intersected a 54-metre zone of substantial nickel-copper sulphide mineralisation at its flagship Mons project.

The find sent its shares up by as much as 33 per cent to trade at 24¢ by 9.30am on Wednesday. It closed trade at 23¢.

The Perth-based junior has had a tumultuous time in recent months, with its share price sinking 42 per cent on June 29 following lithium assay results from Mons that disappointed the market.

Nimy had a resurgence earlier this month with its shares rocketing over 40 per cent between October 2 and October 4 on the back of initial nickel-copper hits at Mons.

The junior explorer’s share price is down around 6 per cent over the past year.

Nimy executive director Luke Hampson said the latest results from Mons were a “game-changer” for the company.

“Importantly, the result is entirely consistent with the conductor plates we have modelled using geophysics,” he said.

“In light of this result, we are moving quickly to do DHEM and FLEM surveys to gain further understanding of the size of the intrusive and to locate related anomalies around and below the discovered sulphide zone.”
