New World Resources Limited (ASX: NWC) has intersected significant new massive sulphide intercepts in its ongoing drilling programme at the historic, high-grade Antler Copper Project in Arizona, USA.
Recent drilling has been targeting:
- Depth extensions of the very thick, high-grade mineralisation that extends down-dip from the historical workings, which remains completely open at depth; and
- The poorly explored strike extensions of the Antler Deposit, particularly to the south, where strong Induced Polarisation and magnetic anomalies coincide with outcropping mineralisation that has been mapped to extend over more than 750m of strike.
Two diamond drill holes completed during the past week have encountered significant intercepts of massive and semi- massive sulphide mineralisation.
Managing Director, Mike Haynes, said that for the past 6-8 months, the company has been systematically drilling deeper holes below the historical workings at the Antler Deposit, as it has discovered a continuous, thick, shoot of high-grade mineralisation that remains open at depth.
Results returned recently from the deeper levels of this “Main Shoot” include:
- 23.3m @ 3.48% Cu, 8.84% Zn, 1.24% Pb, 64.4 g/t Ag and 0.50 g/t Au (23.3m @ 6.7% Cu equivalent) in drill hole ANTRCDD202020;
- 23.1m @ 2.56% Cu, 5.57% Zn, 0.66% Pb, 36.1 g/t Ag and 0.30 g/t Au from 456.3m (23.1m @ 4.5% Cu equivalent*) in ANTDD202021; and
- The intersection of 24.5m of copper and zinc- rich massive sulphides in the previous deepest hole the Company had drilled at the Project, ANTDD202144 (assays pending).
New World has recently completed an additional hole to continue to evaluate the depth extensions of the deposit – ANTDD202153. This is the deepest hole the Company has drilled to date.
Significantly, the hole intersected a total of more than 17 metres of very well mineralised material (within an overall 30m-thick mineralised interval) approximately 65m down-dip from the mineralisation intersected in the company’s previous deepest hole, ANTDD202144. Assay results for this new hole are pending and expected in April 2021.
Mr Haynes said this extends the thick high-grade mineralisation in the Main Shoot to more than 450m down-plunge from the deepest historical stopes (previously 400m) and more than 600m down-plunge from outcropping mineralisation at surface.
Follow-up drilling has commenced to continue to evaluate the depth extents of the Main Shoot.
This is another significant achievement in our exploration of the Antler Copper Deposit,” Mr Haynes said.
“In the past week, we have completed the deepest holes we have drilled so far in both the Main Shoot of thick high-grade mineralisation, which we now know extends more than 450m down-plunge from the historical workings, as well as in the recently discovered South Shoot along strike from the main workings. These holes have both intersected more than 17m of very good-looking mineralisation.
“This bodes well for the potential to expand the resource base at Antler. And the thick, high-grade, nature of the mineralisation intersected should continue to positively impact the economics of our plans to resume mining operations in the near term.”
