Corazon identifies high-grade nickel-copper

THE DRILL SERGEANT: ASX-listed Canada-focused exploration company Corazon has intersected approximately 50 metres of sulphide mineralisation from 771 metres down-hole, including three zones of high-grade semi-massive to massive nickel-copper sulphide breccia, at its Lynn Lake nickel sulphide project.

The result comes from an ongoing exploration hole, which is currently being drilled at Lynn Lake.

“The intensity of the mineralisation is some of the strongest observed at the Lynn Lake Project to date, and is significantly greater than anything the company has drilled in the upper parts of the EL Deposit and resource area,” Corazon Mining said in its announcement to the ASX.

Visual analysis carried out by Corazon of the drilling so far along with results from a hand-held XRF instrument supports the company’s belief in the existence of nickel and copper mineralisation at the project within a breccia internal to the ultramafic intrusion.

The current hole is a follow up drill hole to a discovery hole, which the company completed in May this year.

This hole returned:

–    23.75 metres at 3.34 per cent nickel, 1.54 per cent copper and 0.079 per cent cobalt from 731.25 metres, targeting down plunge extensions to the historic EL Mine.

The company said the current drilling has now established a down-plunge extent to mineralisation of at least 100 metres between the discovery hole and the latest hole while remaining open to the south and at depth.

“This is a significant discovery and supports the existence of a breccia body similar to the high grade nickel/copper/cobalt sulphide mineralisation mined at surface within the EL mafic/ultramafic pipe,” the company said.

“The reported intercept does not represent a true width for the mineralisation.

“At this stage the orientation of the mineralisation is uncertain. Analogous mineralisation outcropped at surface and was mined to 210 metres depth at a consistent diameter of between 80 metres and 120 metres, pertaining to the ultramafic core of the intrusion.”

Corazon has now drilled seven holes into this target, which had initially defined by drilling and verified by downhole EM geophysics.

All of these holes have intersected high-grade mineralisation and support the company’s interpretation that the EM conductors recently defined are likely to represent substantial zones of high-grade nickel/copper sulphide.

Results of drilling within the EM conductors include:

–    23.53 metres at 1.46 per cent nickel, 0.54 per cent copper and 0.036 per cent cobalt from 718.47 metres;

–    23.75m at 3.34 per cent nickel, 1.54 per cent copper & 0.079 per cent cobalt from 731.25 m, including 13 m at 4.27 per cent nickel & 0.89 per cent copper;

–    2.30m at 3.84 per cent nickel, 0.41 per cent copper & 0.092 per cent cobalt from 715.25 m; and

–    1.42m at 3.99 per cent nickel, 0.36 per cent copper & 0.027 per cent cobalt from 724.00 m, and 6.00m at 1.89 per cent nickel, 1.17 per cent copper & 0.048 per cent cobalt from 739.00 m;

The company said all holes except for one are believed to have intersected the upper-northern parts of the targeted EM conductor.
