Cyprium Metals Limited announced that assay results have been received from the Nifty East infill extensional drilling. The program comprised 21 RC holes for 5,725m targeting areas from the previous program which identified encouraging widths of oxide/transitional mineralisation extending east and sulphide mineralisation extending east at depth beneath the former Nifty open pit. Section 102,800E: Hole 21NRSP021 confirmed oxide mineralisation that was previously intercepted in holes 21NRSP006 and 21NRSP011.

Hole 21NRSP021 also extended sulphide mineralisation at depth within the carbonate-shale host rocks (4m at 0.36% Cu, 3m at 0.47% Cu and 17m at 0.52% Cu, including 2m at 1.14% Cu and 6m at 0.16% Cu). Hole 21NRSP030 confirms oxide mineralisation close to surface that was previously intersected in hole 21NRSP001 and historical drillhole NCP0317. Three deeper holes intercepted sulphide mineralisation extensions at depth where there is no historical drilling.

Hole 21NRSP0022 intercepted 3m at 0.19% Cu, 11m at 0.66% Cu including 2m at 1.57% Cu and 3m at 0.31%, and 5m at 0.51% Cu including 1m at 1.40% Cu. Hole 21NRSP0031 intercepts include 6m at 0.33% Cu and 7m at 1.14% Cu including 4m at 1.76% Cu. 21NRSP0032 intersected 3m at 0.21% Cu, 3m at 0.29% Cu and 4m at 0.20% Cu.

The drilling has identified further extensions to the oxide mineralisation east of the Nifty pit. The mineralization is mostly in proximity to the northern limb of the Nifty Syncline. It has also been confirmed to extend further south, interpreted as an extension of the sub-parallel zone of supergene copper mineralisation, which was identified in the first phase of drilling by Cyprium Metals in 2021.

Hole 21NRSP0033 (4m at 0.14% Cu, 3m at 0.16% Cu, 6m at 0.22% Cu, 14m at 0.27% Cu, 5m at 0.17% Cu and 3m at 0.26% Cu) and Hole 21NRSP034 (3m at 0.13% Cu, 4m at 0.16% Cu, 3m at 0.19% Cu, 4m at 0.70% Cu including 2m at 1.17% Cu, 3m at 0.30% Cu, 5m at 0.32% Cu and 1m at 1.23% Cu) have confirmed oxide and transitional mineralisation previously unidentified. The sub-parallel zone of supergene mineralisation was intercepted by hole 21NRSP024 (5m at 0.47% Cu including 1m at 1.36% Cu and 4m at 0.11% Cu). This hole also confirms sulphide mineralisation at depth (13m at 1.08% Cu including 1m at 1.12% Cu and including 3m at 3.10% Cu).

The drilling has confirmed oxide and transitional mineralisation previously identified in historical holes. New extensions to sulphide mineralisation to the east and at depth have also been identified. Hole 21NRSP035 confirms intercepts of shallow oxide and deeper transitional mineralisation (4m at 0.16% Cu, 7m at 0.16% Cu and 8m at 0.24% Cu).

Hole 21NRSP026 has intercepted the southern sub-parallel zone of supergene copper mineralisation (6m at 0.16% Cu). Sulphide mineralisation within the Nifty Syncline carbonate-shale host rocks was intercepted at depth (7m at 0.30%, 7m at 0.34% Cu and 4m at 0.20% Cu). Sulphide mineralisation was intersected higher in the stratigraphic sequence in hole 21NRSP0025 (13m at 0.52% Cu including 1m at 1.48% Cu and including 1m at 2.13% Cu) and at depth (3m at 0.42% Cu and 4m at 0.19% Cu).
