onlyNew Century Delivers Strong June Quarter Production and Drilling Results
Highlights
Strong quarterly production results from Century operations:
31,699t of zinc metal produced during the June 2022 quarter, up 14% on March quarter
Full year revised production guidance achieved in mid-range, with 118,108t zinc metal produced
C1 costs expected to be mid-range of guidance of US$0.85/lb to US$0.95/lb (pending reconciliation)

Advancements in the Century expansion: | |
Watson's Lode drilling, targeting increased Mineral Resource confidence and potential conversion to | |
a mineable Ore Reserve, has delivered exceptional shallow, high-grade drill intercepts: | |
o 7.0m @ 43.2% Zn + Pb from 66m (40.4% Zn, 2.8% Pb, 28g/t Ag) downhole | |
o 4.0m @ 26.4% Zn + Pb from 61m (20.3% Zn, 6.1% Pb, 5g/t Ag) downhole | |
o 7.5m @ 16.9% Zn + Pb from 134m (16.8% Zn, ≤0.1% Pb, ≤0.5g/t Ag) downhole | |
o 4.8m @ 13.7% Zn + Pb from 87m (13.6% Zn, ≤0.1% Pb, ≤0.5g/t Ag) downhole | |

| Watson's Lode remains open along strike, which is to be tested on conclusion of current program |
(current Inferred Mineral Resource of 1.74Mt @ 9.7% Zn + Pb covers ~700m of known ~4km strike)
Lilydale prospect identified as a high potential target, with stratigraphy and structural setting similar to the original Century 'Big Zinc' ore body (drilling scheduled for September quarter)

Lilydale Prospect
The Lilydale prospect sits adjacent to and stratigraphically above the Watson's Lode vein and targets the younger Century host sequence. The area has a similar cluster of veins to those around the original
onlyCentury 'Big Zinc' deposit. These veins are considered a potential feeder within the larger system.
Historic geochemical anomalies of zinc, lead, and manganese have been identified in the surrounding soil plains which may indicate the presence of additional economic mineralisation beyond the known veins.
Drilling at Lilydale aims to intersect the Century stratigraphy proximal to the Watson's Lode and Lilydale structures, to gain insights into the relative timing of the vein forming events and the fertility of the Century host unit locally.
The potential of the area is considered analogous to the satellite Teena deposit (58Mt @ 11% Zn, 1.6% Pb)1 relative to the larger HYC (McArthur River) deposit (227 Mt @ 9% Zn, 4% Pb, 40g/t Ag)1.
The Company plans continued drilling across the historic vein field seeking incremental and value accretive sources of feed, in addition to the planned Silver King mine.
