Health, Safety and Environment

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


During the quarter, 2,575 tonnes of ore were mined at Plomosas, which was lower than the previous quarter of 9,987 tonnes, primarily due to the COVID-19 suspension of operations.

Stope mining proceeded at the Semi-Oxide Ore (SOX) stopes between level 7 and Level 9 and a new stoping area at Las Espadas was opened up increasing available stope areas to 6.

All labour contracts were revised at Plomosas to align the objectives of the employees with that of the Company’s Key Performance Indicators (KPI) by lowering base rates and increasing KPI based bonuses. The labour contract revisions have reduced operating costs.

Mining costs started the quarter at US$85/t hauled to the surface and by late June had reduced to US$44/t, with the average quarterly mining costs at US$49/t. Mining costs are trending favourably with tonnes mined increasing and the unit cost per tonne reducing.


During the quarter 2,201 tonnes of ore were processed at average milled grades of 16.6% zinc, 9.2% lead and 64 g/t silver.

Significant operational improvements were made at the Aldama concentrator under the Company’s guidance during the Covid19 required shutdown. The maintenance team improved the crushing circuit availability, while the plant pumping systems and flotation mechanics were serviced. These works resulted in a significant improvement of availability on restart with 94.5% availability versus 68% availability prior to the shutdown.

Operations did not recommence until 21 June 2020 due to the COVID-19 impacts on the supply of key equipment and personnel availability.

At the end of the quarter inventory stockpiles were 1,087 tonnes of ROM ore available for processing and 293 tonnes of zinc concentrate and 100 tonnes of lead concentrate.

Operating Costs

The June 2020 quarter C1 operating costs were $0.84 per payable pound of zinc sold which was 20% lower than the previous quarter ($1.05/lb), due to the following factors:

  • Owner operated mining allowed for improved efficiencies however, this was partly offset by lack of mechanical availability of rental equipment used during the transition while waiting for delivery of purchased mining equipment; and
  • Plant production was limited to 15 days in 91-day quarter.

The Company expects the trend of reduced operating costs to continue, as cost savings related to the labour efficiencies, improved plant performance and a full quarter of steady state operations are reflected in the operating costs.


Concentrate Sales

541 tonnes of zinc concentrates and 201 tonnes of lead concentrates were sold in the quarter.

At the end of the quarter, 293 tonnes of zinc concentrate, and 100 tonnes of lead concentrate were stockpiled and scheduled for sale in in Q3 2020.


During the quarter $0.057 million of exploration expenditure was incurred.

Resource Update

During the quarter, the Company announced the results from the incorporation of the Inferred to Indicated resource category conversion drilling into the updated resource model. Refer to the ASX announcement dated 29 April 2020 for full details.



Regional exploration during the quarter has demonstrated the presence of high-grade, narrow vein gold mineralisation that pinches and swells along strike. Three separate areas of gold mineralisation have been identified for initial follow up and more work is planned to confirm and identify additional targets.

At the La Chona- Enrique prospect, the veins swell to over 1.5m width and previous mining has seen the development of stopes to 16 metres depth.

The Potrero prospect contains gold veins which have been mined along 300 metres of continuous surface veins at a time when no modern exploration techniques were applied.

The Northern Extension Targets comprising the Javier, Jose and Alfonso prospects where a felsic intrusion appears to have been truncated by regional deformation faulting may host classic traps for gold fluid to pool.

At all of these priority prospects, further work is planned to better understand the gold mineralisation and define targets prior to drilling. A scope of works has been defined and once COVID-19 restrictions allow for the mobilisation of exploration personnel to site, the Company plans to re-commence planned exploration prior to drilling the targets later this year.

Refer to the ASX announcement dated 23 April 2020 for the full details of the gold regional exploration results.


Board fees and Executive salaries reduction

The Board and management recognise the impact of the COVID-19 on shareholder value and cashflow. In response the non-executive Directors have voluntarily reduced their fees by 50%, and the Managing Director and Chief Financial Officer voluntarily reduced their salaries by 20%. These initiatives will remain until the Board sees a return to pre COVID-19 commodity prices and operating conditions normalise.


In early April 2020, the Mexican Government issued a COVID-19 related decree to shut down all non-essential services, which included all mining operations at that time. However, from 1 June 2020, the mining sector was deemed to be an essential service, allowing operations to re-commence.

The Company has put in place stringent health, safety and hygiene standards at its operations to identify any COVID-19 risks and minimise the risk of transmission amongst its employees and contractors. No cases of COVID-19 have been reported to date at our two operational sites.

During the shutdown period, maintenance was completed enabling the removal of hire equipment and employee contracts were renegotiated to better align remuneration with performance. Supplier contracts were also reviewed and renegotiated where possible.

Capital Raisings

During the quarter, CZL completed a fully underwritten Entitlements Offer and Placement.

The Company announced a fully underwritten pro-rata non-renounceable entitlements offer (“Offer”) on 23 April 2020 to raise A$1,725,933 on the basis of 1 new share (“New Share”) for every 3 shares held at the record date, at an issue price of $0.003 per New Share which closed in accordance with the Offer timetable.

Subscribers in the Offer received one (1) free-attaching option (New Option) for everyone (1) New Share subscribed for and issued, exercisable at $0.006 per New Option on or before 1 June 2023.

The Company announced on 11 June 2020, following the strong support from shareholders in the completed Offer, firm commitments to raise a further A$570,000 via a single tranche placement of 190.0 million new fully paid ordinary shares (“Placement Shares”).

The Placement was on the same terms as the Entitlement Issue, i.e. at an issue price of $0.003 per Share, together with one (1) listed option for every one (1) Share subscribed in the Placement (exercisable at $0.006, expiry date 1 June 2023, listed under ticker ‘CZLOB’ (Placement Options)). The Placement Options are subject to shareholder approval at the annual general meeting to be held on 31 July 2020.

Funds raised from the Offer and Placement have or will be used for exploration of gold prospects at the Plomosas project, to repay unsecured loans, for working capital, purchase of equipment to increase efficiencies at Plomosas and to meet the Offer and Placement expenses.


The Company’s closing cash at the end of the quarter was US$0.745 million (prior quarter $0.298 million).

Trade Receivables

The Company’s trade receivables due from the sale of zinc and lead concentrates was $0.118 million (prior quarter $0.473 million) and VAT refundable of $1.172 million (prior quarter $1.273 million).

VAT refunds from the Mexican government are denominated in Mexican Peso and recoverable through a combination of cash refunds and offsetting against any monthly VAT payable amounts due to the Mexican government.

The invoice value of zinc and lead concentrate stockpile at the end of the quarter $0.237 million.

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.
