Base Metals: The zinc, lead silver hits just keep getting better for Alta in Italy
Alta Zinc’s (ASX:AZI) maiden drilling program at the Pian Bracca prospect within its Gorno project in northern Italy is off to a flying start with the first hole exceeding the average grade and thickness of any hole drilled within the project’s recent exploration history.
This hole intersected 10.6m at 9.5 per cent zinc plus lead and 34 grams per tonne (g/t) silver from a depth of 36m, and a shallow, higher grade zone of 2m grading 16.1 per cent zinc plus lead and 23.4g/t silver from a depth of 18m.
A second hole also intersected two separate lenses of mineralisation with intersections of 12m and 2m respectively.
The company said the results to date confirmed its geological model for the Pian Bracca prospect, with more than 30 holes still to be completed.
“These first results from our Pian Bracca drilling campaign demonstrate that both the grade and thickness of the mineralisation at Gorno can be significantly greater than has been shown by the nearby Zorzone drilling,” managing director Geraint Harris said.
“As we continue the step-out drilling it will be exciting to see the potential for mineralised extensions, hopefully continuing to confirm the high grades and thicknesses indicated by our channel samples located further to the east and west of these holes.”
In the Northern Territory, KGL Resources (ASX:KGL) has intersected further high-grade copper just below and south of the proposed pit at the Reward deposit within its Jervois project.
Notable results include 17.9m at 3.9 per cent copper, 97.1g/t silver and 0.38g/t gold from a depth of 117.5m and 29.4m at 2.56 per cent copper from 182.7m in the same hole and 65m at 3.6 per cent copper, 98.6g/t silver and 0.45g/t gold from 210.3m.
“Coming after the high-grade results announced three weeks ago, the intersections are very positive,” KGL chairman Denis Wood said.
“They are just below the proposed pit outline at Reward, they come while detailed mine planning is in progress at Jervois, and so they present the company with even more options to increase the scale and improve the costs of the operation.”
Additionally, down-hole electromagnetic surveys have located a new conductor zone just south of the Reward pit.
Coppermoly (ASX:COY) has uncovered substantial widths of copper-zinc mineralisation from trenching at the Nakru-2 North-West prospect in Papua New Guinea. This returned a top result of 11m at 4.13 per cent copper and 9.04 per cent zinc and 14m at 5.16 per cent zinc.
