• Completed 100% acquisition of Plomosas in September 2019, acquiring the remaining 10% interest, in exchange for a 1.0% net smelter return royalty
  • First full quarter of production from the third party Aldama concentrator, processed up to 266 tonnes ore day during September
  • 7,511 tonnes ore mined during the quarter grading 13.5% zinc and 8.2% lead, down from the June quarter as the Company processed significant ore stockpiles
  • 9,120 tonnes of ore processed at 12.5% zinc and 7.9% lead, down from the June quarter due to one off events (power outages, high lightning strikes)
  • Payable metal sold of 773 tonnes of zinc, 273 tonnes of lead and 854 ounces of silver in concentrate, up from the June quarter as the Company sold down stockpiles

    • 256 tonnes of zinc concentrate, and 106 tonnes of lead concentrate stockpiled and available for sale
  • C1 cash cost of payable zinc sold $1.01/lb, primarily higher than the June quarter due to the temporary increase in development costs incurred to access the high-grade SOX orebody in the December quarter and an industry wide increase in smelter treatment charges
  • Significant operational improvements at the mine and processing plant have resulted in positive cash flows generation from the Plomosas operations in October
  • Drill plans finalised to follow up LV5040 which identified 3.75m (TW) at 37.5% Zn+Pb potential extension of mineralisation down dip of the current JORC resource.

OPERATIONS – PLOMOSAS MINE, CHIHUAHUA STATE, MEXICO (100% OWNED)

Health, Safety and Environment

There were no reportable environmental or safety incidents during the quarter.

Mining

During the quarter 7,511 tonnes were mined at Plomosas, which was lower than the previous quarter at 15,881 tonnes due to a decision taken to reduce high run-of-mine (ROM) stockpile balances which peaked at 7,301 tonnes during the quarter.

Mining unit costs for the quarter were higher than planned due to the use of on-ore development mining methods, which was at a substantial cost premium to lower cost stope mining.

The use of this higher cost mining method is temporary and was selected to establish the development required for stope mining of the semi-oxide (SOX) orebody. Stope mining will enable higher rates of mining of the high-grade SOX mineralisation. Ore was extracted from ore strike drive development at the 921mRL, 913mRL and a decline from 921mRl to 900mRL where old working established an ore strike drive along 200m of SOX ore. The decline was then advanced to the 888mRL level.

The ore strike drives established at 921mRL, 913mRL and 888mRL along with the previously established strike drive at 900mRL will form the basis for sublevel development between 875mRL and 921mRL levels. Sublevels at 12.5m  intervals will then allow for mining of the SOX ore with up-dip stopes extending 30m. The development will be completed in the December quarter and stoping will them be undertaken between 875mRL and 921mRL along 200m of SOX strike length for 120m up dip stoping.

The benefits of stope mining which will commence during Q4 2019 is that it permits the mining of increased tonnages of higher-grade ore with lower mining dilution. This will lead to lower mining costs, higher processing throughputs and higher head grade in Quarter 4.

TABLE 1. QUARTER ENDED 30 JUNE 2019 PRODUCTION STATISTICS

Processing

The Company is pleased to report that it is seeing early results from the upgrade of the Aldama processing facility with  ore processing throughput at Aldama improved significantly towards the end  of quarter, operating at up to 266 tonnes per day in September.

During the quarter 9,120 tonnes of ore were processed at average milled grades of 12.5% zinc, 7.9% lead and 37.4g/t silver. The target was to operate at 150 tonnes per day during the quarter while 101 tonnes per day was achieved. The plant availability was lower than budgeted with repeated lightning strikes through August and September affecting the grid power supply, with power restoration times taking up to 21.5 hours per lightning related power outage.

Zinc recoveries have reflected the benefits of metallurgical testwork results and towards the end of the quarter recoveries lifted from below 60% to above 70% with recoveries of zinc to zinc concentrate averaging 74% at the end of the quarter.

Lead recoveries have also reflected the benefits of metallurgical testwork resulting in an average 31% of lead to lead concentrate. Specialist studies have been commissioned and alternate reagent additions have targeted increasing the lead recoveries while retaining the higher than expected zinc recoveries.

CZL continues to hold a significant ROM stockpile with 4,424 tonnes held at the end of the quarter to be processed through Aldama in the December quarter.

Corporate

Acquisition of 100% of Plomosas

  • de C.V. The consideration for the acquisition is a 1% Net Smelter Return Royalty (“NSR”) from the sale of zinc and lead concentrates produced from Plomosas.

Placement and Rights Issue

During the quarter, the Company completed a Placement to new sophisticated and professional investors, raising A$1.0 million (before costs) at A$0.011 per share (the “Placement”) and announced a fully underwritten non-renounceable rights issue of 1 new share for every 6 shares held at an issue price of A$0.011per share to raise A$2.48 million (before costs) (the “Rights Issue”). The Rights Issue closed on 4th October 2019, with the Rights Issue shares issued on 10th October 2019.

Cash

The Company’s closing cash at the end of the quarter was $0.30 million (prior quarter $0.20 million) excluding the A$2.48 million raised from the Rights issue which closed post quarter end.

Trade receivables

The VAT refunds are in the process of being recovered through a combination of cash refunds and credits offsetting future VAT payable on the sale of concentrates in each calendar month.

Convertible Notes

During the quarter, A$1.762 million of convertible notes and capitalised interest were converted to fully paid ordinary shares at a conversion price of A$0.01 per share. The closing balance of convertible notes on issue at the end of the quarter was A$1.186 million inclusive of capitalised interest.

The convertible notes on issue have a principal value of A$1.052 million, with:

  • A$0.900 million with a maturity 30 June 2020 at a conversion price of A$ 1.0 cent per share;

ABOUT CONSOLIDATED ZINC

Consolidated Zinc Limited (ASX: CZL) owns 100% of the historic Plomosas Mine, located 120km from Chihuahua City, Chihuahua State. Chihuahua State has a strong mining sector with other large base and precious metal projects in operation within the state. Historical mining at Plomosas between 1945 and 1974 extracted over 2 million tonnes of ore grading 22% Zn+Pb and over 80g/t Ag. Only small- scale mining continued to the present day and the mineralised zones remain open at depth and along strike.

The company has recommenced mining at Plomosas and is committed to exploit the potential of the high-grade Zinc, Lead and Silver Mineral Resource through the identification, exploration and exploitation of new zones of mineralisation within and adjacent to the known mineralisation with a view to identify new mineral resources that are exploitable.
