Investors were liking Mincor Resources’ (ASX:MCR) news today that it had delivered a 52 per cent increase in the resource for its Cassini nickel mine in Western Australia.

Anything over 3 per cent nickel is generally considered high-grade.

Shares gained as much as 6.5 per cent to trade at an intra-day high of 49c on Tuesday.

Over 80 per cent of the resource is now in the higher confidence indicated category.

Mineral resources are categorised in order of increasing geological confidence as inferred, indicated or measured.

By moving resources into the indicated category, it means a company has sufficient information on geology and grade continuity to support mine planning.

Cassini is the first new discovery in the belt in more than 20 years.

Mincor says the updated resource positions the Cassini find as one of the “largest and highest-grade nickel resources in the Kambalda district”.

It is expected to form the cornerstone of Mincor’s strategy to restart nickel production next year.

The company recently inked an off-take deal with BHP Nickel West, which needs more nickel ore for its Kambalda concentrator.

“The program at Cassini has gained pace since we signed the game changing off-take term sheet with BHP Nickel West on 19 March 2019, with our initial objective being to build a high-grade nickel resource inventory capable of supporting at least a four-year mine plan,” managing director David Southam said.

Mincor is aggressively pursuing a further resource upgrade with two rigs currently drilling.

Another resource update is slated to be delivered by the end of June quarter.
