"2020 was a highly successful and pivotal year for the Company, having seen our flagship Hellyer operations finally achieve production rates better than originally forecast from the original mine start-up plan. Hellyer's year end performance, and the revenue boosts associated with production rates of around 1.4 million tonnes per annum, were instrumental in securing a major

2020 saw consistently improving production output at Hellyer, driven by a systematic plan that increased capacity at the plant to around 1.4 million tonnes per annum (mtpa) by year end. This throughput compares to the initial project steady state forecast of 1.2 mtpa and a revised throughput target of 1.5 mtpa planned for the end of Q1 2021. In addition, the Company completed its
Overall production for the 2020 comprised:
· Lead concentrates of 38,319 tonnes - up 53% from the previous year (2019 FY: 24,980 tonnes).
· Zinc concentrates of 19,019 tonnes - up 22% from the previous year (2019 FY: 15,646 tonnes).
Payable gross gold production for 2020 was 5,452 ounces and payable gross silver production was 1,106,440 ounces. These saleable precious metals reported to the lead and zinc concentrates.
The long-term mining and processing plan called for the construction of a new tailings dam at the Hellyer operations. This new tailings dam (TSF2) will service the existing life-of-mine operations from the tailings retreatment project. In addition, this new dam will provide for additional tailings storage capacity in the emptied TSF1 dam for a potential re-opening of the Hellyer underground mining operations, where significant high-grade mineralisation still exists, as previously reported.
Construction of TSF2 commenced at Hellyer in Q4. Tailings deposition into Stage 1 of the new TSF2 is scheduled to start around the end of Q1 2021.The capital cost of Stage 1 TSF2, when completed, will be around Australian
