Jubilee bumps resource at WA nickel project

A new resource figure for the Sinclair nickel deposit near Leonora, Western Australia, is significantly higher than the previous one.

Operator Jubilee Mines (JBM-A) puts the inferred resource at 1.2 million tonnes grading 2.8% nickel, divided between four mineralization types.

Primary nickel mineralization at depth makes up about half the resource, and supergene material — 356,000 tonnes at 3.3% nickel — another third. Ther is a minor contribution from oxidized and transitional types.

Jubilee, which operates the Cosmos nickel mine near Leinster, W.A., has been assembling resources at Sinclair and at two prospects near the Cosmos mine, Prospero and Alec Mairs. At Prospero, it has blocked out 1 million tonnes grading 4.9% nickel in proven and probable categories, and at Alec Mairs it has a high-grade resource of 61,000 tonnes grading 12.9% nickel.
