FINAL DRILLING ASSAYS DEMONSTRATE POTENTIAL FOR INITIAL 'HIGH GRADING' OF ZINC PRODUCTION FROM THE

CENTURY TAILINGS DEPOSIT

  • Assays for all 173 holes of the tailings drilling program now received

  • Continued zinc grades in excess of current Mineral Resource, highlights include:

    o 15.1m at 3.28% Zn, 0.52% Pb & 17.8g/t Ag (TSF166) o 18.5m at 3.17% Zn, 0.48% Pb & 13.4g/t Ag (TSF246) o 16.7m at 3.15% Zn, 0.45% Pb & 13.0g/t Ag (TSF173) o 17.4m at 3.09% Zn, 0.43% Pb & 12.7g/t Ag (TSF249) o 16.1m at 3.07% Zn, 0.45% Pb & 13.2g/t Ag (TSF190) o 20.1m at 3.04% Zn, 0.46% Pb & 14.2g/t Ag (TSF248)

  • Weighted average composite grade of all holes 3.00% Zn, 0.45% Pb, 12.4g/t Ag

  • Calculated dry bulk density (tonnage indicator) 1.90t/m3 vs 1.67t/m3 in Resource

  • Deposit confirmed to have excellent vertical & lateral grade continuity

  • Deposit confirmed to have consistent silver & lead assays

  • High-grade zones to provide potential increased production during initial operations

  • Updated Mineral Resource estimation process underway

New Century Resources Limited (Company or New Century) (ASX:NCZ) is pleased to announce the receipt and interpretation of assays from the final 61 holes of the tailings infill drilling program at the Century Zinc Mine in Queensland.

Commenting on the drilling results, New Century Resources Managing Director Patrick Walta stated:

"The results of the drilling program have vastly exceeded Company expectations, showing strong potential for a material increase in both zinc grade and density across the Century Tailings Deposit.

It has also been fantastic to confirm of the consistency in grades across the Deposit. With the grade profile now confirmed, New Century has an opportunity to initially target the defined higher grade sections of the Deposit, providing potential for increased zinc metal output during the first years of production."

The current Century Tailings Resource stands at an Indicated Resource of 12.8Mt at 2.97% zinc and Inferred Resource of 58.2Mt at 2.68% zinc for a total 71.0Mt at 2.73% zinc (1,940,000t of contained zinc metal).

Only the Indicated Resource area (see Figure 1) had been subject to drilling prior to the 2017 program recently completed by New Century. The process for calculation of the Inferred Resource area was via deduction of the Indicated Resource from an assumed total resource, which had been calculated from irregular tailings feed assays and unreconciled tonnage deposition data since commencement of operations in May 2000.

The drilling results received from New Century's 2017 program have produced an average grade of 3.00% zinc. This represents a 10% increase on the global Mineral Resource grade of 2.73% zinc, providing potential for a material increase in global zinc grade across the Century Tailings Deposit.

In addition, based on preliminary results from 137 of 173 holes analysed to date, potential for a material increase in the dry bulk density (and hence Deposit tonnage) has been identified. Preliminary analysis has indicated an average calculated dry bulk density of 1.90t/m3. This represents a 14% increase compared to the dry bulk density value of the global Mineral Resource of 1.67t/m3.

Furthermore, New Century's 2017 drilling program has analysed for lead and silver which were not reported within the existing Mineral Resource estimate for the Century Tailings Deposit. The average of all results received is 0.45% lead and 12.4g/t silver, providing potential for additional payable metal credits in the zinc concentrate.

Cross sections through the current drilling (see Figures 2 to 5) demonstrate the vertical and lateral consistency of zinc grades across the tailings dam, in addition to the continued observation of higher grades compared with the previously reported Mineral Resource. These cross sections also demonstrate strong consistency between the results of the 2015 and 2017 drilling programs.

A vertical exaggeration of 20:1 has been applied to all cross sections for purpose of grade interpretation at the metre scale. All holes drilled in 2017 were at 125m grid spacing.

Figure 1: Century Tailings Deposit drilling overview

As shown in Figure 1, the entire Century Tailings Deposit is consistently mineralised, with a notable higher grade weighting toward the SE corner of the Deposit. This is also the deepest part of the Deposit with holes averaging approximately 20m in depth compared to a 13m Deposit average.

This higher grade zone provides an opportunity for increased production during the initial years of future operations and is planned to be targeted in the mine schedule as part of the Restart Feasibility Study currently underway by Sedgman.
