Kumarina results continue to flow for Horseshoe Metals
THE DRILL SERGEANT: Horseshoe Metals (ASX: HOR) has received results from exploration activities being conducted at the company’s 100 per cent-owned Kumarina copper project and Horseshoe Lights copper/gold project in Western Australia.
The company has completed its latest phase of Reverse Circulation percussion (RC) drilling at the Kumarina project with drilling undertaken in the Rinaldi, North Show, Review East and Kumarina copper mine areas.
The primary aim of the drilling was to test for extensions of copper mineralisation identified in 2011 drilling programs.
Horseshoe drilled 13 holes at the Rinaldi prospect with the latest drilling in this area encountering shallow extensions to the copper mineralisation previously identified.
Results included:
– 24m at 3.1 per cent copper from 46 to 70 metres, including 3 metres at 12.3 per cent copper and 1 metre at 9.4 per cent copper;
– 7m at 5.9 per cent copper from 12 to 19m, including 2m at 13.6 per cent copper;
– 3m at 4.2 per cent copper from 11 to 14m, including 1m at 7.5 per cent copper; and
– 5m at 2.2 per cent copper from 17 to 22m, including 1m at 3.9 per cent copper.

“The shallow copper mineralisation observed in these holes occurs as malachite within the weathered zone,” Horseshoe Metals said in its ASX announcement.
“Lower grade intervals of copper were recorded in eight of the nine remaining holes drilled in the immediate Rinaldi Prospect area.”
Horseshoe drilled an additional 18 holes further to the north to test for northward extensions of the Rinaldi Prospect copper mineralisation.
Low grade copper mineralisation was recorded in four of these holes, which the company said confirmed copper mineralisation extends for a distance of at least 600 metres north from the Rinaldi shaft.
“Observations from the latest drilling confirm that the copper mineralisation at the Rinaldi prospect is predominantly quartz vein hosted, with the main concentration of quartz veins occurring within a quartz diorite sill,” Horseshoe explained.
“However the copper mineralisation appears to be structurally controlled within a north-south fault zone.”
Another 3 holes were drilled at the North Show prospect to test for extensions to copper mineralisation identified in the 2011 drilling.
All holes intersected low grade copper mineralisation with best intervals recorded of 6m at 0.4 per cent copper (13-19m) and 10m at 0.3 per cent copper (23-33m).
At Review East 2 holes were drilled about 100m south-west of historic workings.
Both holes intersected low-grade copper mineralisation of up to 4m at 0.4 per cent copper.
Horseshoe considers this to have confirmed the presence of copper in a NE-SW orientated fault.
“This fault runs through the Review East prospect and appears to be a dislocated extension of the NE-SW fault running through the North Show prospect which is located about 3 kilometres to the south-west,” the company said.
Two holes drilled at the Kumarina copper mine prospect failed to intersect any significant copper mineralisation.
Despite this result Horseshoe said the geological information obtained will assist in the planning of future drilling at this prospect.
Horseshoe Metals is starting a follow-up RC drilling program this week at the Kumarina project.
The drilling program will focus on in-fill and step-out holes at the Rinaldi prospect.
