New World Resources Limited (ASX: NWC) has received significant new high- grade assay results from nine recently completed drill-holes at the historic Antler Copper Project in Arizona, USA.
Recent drilling has been targeting:
- Extensions of the very thick, high-grade mineralisation that extends down-dip from the historical workings, which remains completely open at depth – the “Main Shoot”; and
- The poorly explored strike extensions of the Antler Deposit, particularly to the south, where, exploratory drilling in late 2020 discovered a new shoot of thicker mineralisation that remains open at depth – the “South Shoot” (see NWC’s ASX Announcements dated 2 and 12 March 2021).
Having completed ground magnetic and Induced Polarisation (IP) surveys over and along strike from the Antler Deposit between June and September 2020, the company began drilling in the area to the south of the historical workings in October, to test for strike extensions of the mineralisation.
The first hole the company drilled in this area intersected a thick zone of mineralisation. New World subsequently drilled a series of follow-up holes to explore for the extensions of this thick, high-grade mineralisation.
Assay results have now been received for six of the initial holes. Significant mineralisation was intersected in all these holes, with exceptional results returned from ANTDD202030, which intersected two very high-grade zones of mineralisation only 8m apart, comprising: 6.2m @ 4.05% Cu, 12.13% Zn, 1.59% Pb, 50.9 g/t Ag and 0.24 g/t Au from 343.4m (6.2m @ 7.2% Cu equivalent); and 6.7m @ 5.87% Cu, 13.74% Zn, 0.18% Pb, 41.1 g/t Ag and 0.30 g/t Au from 357.8m (6.7m @ 8.9% Cu equivalent).
We are really pleased to have received these outstanding assay results that reaffirm we have a really prospective, very-high-grade near-term development proposition in Antler,” Managing Director, Mike Haynes, said.
“The exceptionally high grades returned from one of the discovery holes drilled into the new South Shoot is a particularly encouraging development. In that hole, a 6.2m thick interval averages 7.2% copper-equivalent and only 8m further down the same hole a different 6.7m thick interval averages almost 9% copper-equivalent. This adds extremely valuable high-grade tonnes to our resource base, in a newly discovered area.
“Additionally, we now have assays for a new 7.1m thick intersection in the shallower part of the Main Shoot that averages almost 10% copper-equivalent. While one of the deepest holes we now have assays for in the Main Shoot has returned a 19.1m-thick intersection that has assayed 3.3% copper-equivalent. We continue to add substantial and valuable high-grade tonnes there as well.
“Antler continues to emerge as one of the highest grade undeveloped copper deposits globally. It is a very exciting discovery and very real near-term development proposition.”
Significantly, the company recently reported visual results from subsequent follow-up drilling which intersected a 17 metre interval of predominantly massive and semi-massive sulphide copper and zinc-rich mineralisation in drill hole ANTDD202156 – the deepest hole drilled to date in the new “South Shoot”
The down-dip extent of the South Shoot now stands at around 250m, with the mineralisation remaining completely open at depth. Assay results for ANTDD202156 and several other proximal holes are pending.
