Aircore drilling at Legend Mining’s (ASX: LEG) Rockford project in Western Australia has returned nickel-copper sulphide mineralisation, confirming a third mineralised intrusive body.
The company requested a trading halt this morning before announcing the assay results of a further 24 holes of an ongoing drilling program at Area D of the project located in Fraser Range in WA’s south.
Highlights included a 21m intersection grading 0.34% nickel, 0.05% copper and 0.04% cobalt from 64m, including 4m at 0.64% nickel, 0.07% copper and 0.06% cobalt from 72m.
Another intersection was 37m wide and graded 0.25% nickel, 0.03% copper and 0.04% cobalt from 78m.
This third intrusion lies east of two previously identified bodies, announced in April and earlier this month.
The company also noted that anomalous nickel-copper assays in three of the new holes, located about 800m east of two holes confirming the second intrusion, were interpreted to be part of the same body, thus greatly increasing the size of this second intrusion.
Legend managing director Mark Wilson said the new results supported the company’s earlier statements that “Area D is prospective for multiple such intrusions”.
“We see these and other recent results as demonstrating the prospectivity for nickel-copper-cobalt deposits at not only Area D but the whole of our Rockford project and indeed, the entire Fraser Zone,” Wilson said.
Rockford Area D
The Rockford project comprises 12 granted exploration licences of which Legend holds interests ranging between 70% and 100%. Area D lies close to the centre of the total project area.
Initial assay and petrology results from the first three holes of the ongoing aircore drilling program were announced back in April, with improvements shown with each announcement.
Last week, further assay results confirmed the second mineralised intrusive body. Highlights included a 19m intersection grading at 0.23% nickel, 0.33% copper and 0.02% cobalt from 52m.
A comprehensive geophysical review of all data from Area D is currently underway, Legend stated.
The company also plans to conduct a regional aircore program over selected targets in the southern portion of the Rockford project.
Legend’s share price had jumped 7.14% to A$0.045 on the news by afternoon trade.
