  • Bankable Feasibility Study Completed


Consolidated Zinc Limited (ASX:CZL or “the Company”) is pleased to present the September 2018 quarterly activities report.

OPERATIONS – PLOMOSAS MINE, CHIHUAHUA STATE, MEXICO

Health, Safety and Environment

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

Toll Treatment and Offtake Agreement

The Group has entered into a twelve month Toll Treatment and Offtake Purchase Agreements (“the Tolling Agreements”) with Grupo Mexico.

The Plomosas ore will be processed through Grupo Mexico’s Santa Eulalia concentrator with the resulting zinc and lead concentrates sold to Grupo Mexico in accordance with the terms of the Tolling Agreements for refining at the San Luis Potosi zinc smelter located in Mexico. The sale of the concentrates within Mexico delivers substantial logistics and commercial savings. For further details of the Tolling Agreements refer to the ASX announcement dated 5 September, 2018.

Mining

Following approval by the Company to proceed with the Tolling Agreement, the mining contractor rapidly mobilised and was ready to commence mining by 13 September, 2018. First ore was hauled to the surface on 19 September, 2018.

Mining commenced at Level 5 with extraction from ore strike drives north and south in the Tres Amigos zone and a north strike drive in the Tres Amigos North mineralised zone.

The decline bypass, detouring around the zig zag bottleneck in the decline, has commenced and will be completed in the December quarter allowing for reduced haulage cycle times, improving both productivity and production.

**Mined grade was impacted by low grade material derived from strike drive and access development (442 tonnes) while 342 tonnes grading 13.1% Zn, 2.9% Pb were mined from stopes in the latter part of September.

All Plomosas mine and site support service costs were capitalised during the development and commissioning phase of operations and will be capitalised until commercial production is achieved.

The total expenditure capitalised as mine development and property, plant and equipment for the quarter was US$275,000 (inclusive of site support services).

Relative spatial locations of resources are shown with proximity of shafts and underground development and areas with potential for future extension and infill resource drilling. Note extensive down dip extent identified for Tres Amigos whose strike extent has remains untested and is confined by the lack of drilling.
 
Processing

Plomosas ore deliveries to the Santa Eulalia concentrator commenced on 20 September, 2018, with Santa Eulalia building the first stockpile in advance of commencing the first campaign batch treatment in October.

Revenues generated from the sale of zinc and lead concentrates mined and produced during the commissioning period will be capitalised during mine development in accordance with Australian Accounting Standards.

Bankable Feasibility Study

The Detailed Costing Study (“DCS”) was completed and incorporated into a Bankable Feasibility Study (“BFS”). It was submitted to banks and merchant trading houses for review and several finance offers were received comprising debt and/or offtake and equity funding and funding term sheets were provided. A Mexican bank experienced in mine resource debt funding offered a US dollar debt facility, the terms of which were considered favourable and would have funded the proposed development plan including commencement of mining, refurbishment of the concentrator at Plomosas and expansion of the tailings dam.

Subsequent to these offers of finance, a proposal was received from Grupo Mexico for the toll treatment of the Plomosas ore at their nearby Santa Eulalia concentrator and the sale of the resulting zinc and lead concentrates to the Grupo Mexico smelter.

The Grupo Mexico proposal was considered far superior to the options presented in the DCS and BFS, particulalry in the short to medium term. It resulted in Plomosas being brought into production far sooner than originally planned, with a much reduced capital requirement and operating cost benefits in both processing and transport.

The BFS completed to date will be used as a basis for ongoing studies into expanded operations in line with future Resource improvements and exploration success.

Environmental Permits for Operations

During the quarter the Mexican Environmental Authority (PROFEPA) provided the Company with an MIA Exception (EPA exception) for the mine and processing plant area. This MIA exception issued for the mine and process plant allows the Plomosas mining operations to commence whilst the environmental approval process continue for the remainder of the site and tailings storage facility (TSF).

Work will continue into the next quarter on the baseline study for the new design for the TSF and surface buildings to support the mine’s ongoing operations and planned expansion.

While current mining activities do not utilise a TSF at Plomosas, CZL considers it prudent to have all permits in place to develop a concentrator on the Plomosas mining lease in the event of an expanded mine operation.

 

Corporate

Board changes

Ms Angela Pankhurst commenced on 1 August 2018 as a Non-Executive Director and brings a wealth of international mining, financial and corporate experience to the Board.

Mr Andrew Beigel joined the Board in June 2018 following the resignation of Eduardo Valenzuela as a Director to assist with the Company restructuring. Subsequent to the end of the quarter Mr Beigel resigned as a Director and stepped back into the role as Company Secretary.

Third Party Claim

During the quarter, the Company announced it has received a claim by a company named Pandion Minerals Pty Ltd (“Pandion”) pursuant to which Pandion claims to be entitled to a 10% interest in the Plomosas project at such time as a Bankable Feasibility Study is completed.

The Company considers the claim to be unfounded, and if the claim is pursued it will be defended vigorously.

 

Cashflows and Funding

Cash balance

The closing cash balance at 30 September 2018 was $0.609 million, with the convertible note facilities fully drawn to $3.527 million. Future operational cash surplus are expected to be sufficient to pay down the convertible loans.

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.
