HIGHLIGHTS:
Trial mining and toll treatment operation to start in the September quarter of 2019
Exploitation of high-grade (~15% Zn+Pb) mineralisation to generate early cash flow
Operation is fully funded by A$2M convertible note from major shareholder
Feasibility Study for stand-alone, full-scale mining and processing is continuing
Azure Minerals Limited (Azure or the Company) (ASX: AZS) is pleased to announce that the Board has approved the commencement of trial mining and processing of high-grade mineralisation from its 100%-owned Oposura zinc-lead project, located in Sonora, Mexico.
Planned mine production and processing rate will initially be between 1,500tpm to 3,000tpm (tonnes per month) of mineralised material grading approximately 15% combined zinc and lead with ore processed on a toll treatment basis through a nearby sulphide flotation processing facility. There is scope to increase the mine production rate if additional processing capacity becomes available.
Commenting on the decision to commence trial mining at Oposura, Azure’s Managing Director Mr Tony Rovira said: “This is an exciting step forward for the Company. With minimal upfront capital required, this trial mining operation will provide early positive cash flow and Azure will start to realise value from the asset. Generation of this cash flow will assist in funding completion of the Feasibility Study and meeting other corporate expenses.
“Furthermore, this operation will provide additional confidence for development of the full-scale mining and processing operation at Oposura, while the delivery of high-quality concentrates ahead of full-scale production will support future concentrate marketing and project financing negotiations.
“Azure thanks its major shareholder Deutsche Balaton for its strong and ongoing support of the Company and the development and production strategy the Company is implementing at Oposura.”
FUNDING
Azure has secured financing for the trial mining option at Oposura by entering into a binding commitment with the Company’s major shareholder Deutsche Balaton for it to provide A$2,000,000 in funding via a convertible note. This funding will enable the Company to meet start-up costs and working capital requirements with operations to commence in the September quarter of 2019.
The convertible note will have a term of two years at an interest rate of 12.5% per annum. It will be convertible at any time during the term at the note holders’ election at an effective share price of 14.5 cents (a 38% premium to Azure’s closing share price on 31 May 2019).
The issue of the convertible note is subject to shareholder approval which will be sought at a General Meeting of the Company to be held in July. The Notice of Meeting and Explanatory Memorandum will be despatched to all shareholders shortly.
DETAILS OF TRIAL MINING AND PROCESSING OPERATION
Azure has studied the option of trial mining and toll processing of high-grade mineralisation from Oposura since late-2018. The aim is to deliver early cash flow to the Company to aid in financing the completion of the Feasibility Study and meet other corporate expenses.
Components of the trial mining study have included infill and extensional drilling, upgrading the Mineral Resource, geotechnical studies, mine planning and scheduling, bulk sampling, metallurgical testwork, and negotiations with mining, trucking and processing contractors and off-take companies.
The recently updated JORC Mineral Resource estimate for Oposura (ASX: 8 May 2019) is 3.1Mt @ 5.0% Zn & 2.7% Pb, with 85% classified as Indicated resources and 15% as Inferred resources. Importantly, all mineralised material to be extracted and processed by this trial mining operation is classified in the Indicated resource category.
Included within the Oposura Mineral Resource is an area containing very high-grade, zinc-rich mineralisation, designated by Azure as the Tunnel D HG zone. This mineralisation occurs on the western side of the East Zone deposit and is accessible via the existing underground drive, Tunnel D. Specifically targeted, close-spaced infill drilling comprising more than 20 holes with a hole spacing of less than 25m x 25m defined the lateral extent, internal continuity, tonnage and grade of this highgrade area (see Figures 1 & 2).
Some of the better Tunnel D HG mineralised intersections (ASX: 22 May & 24 October 2018) include:
Based upon the updated Mineral Resource model, the Tunnel D HG zone is estimated to contain sufficient high-grade mineralised material to support the planned trial mining operation for at least 12 months at average grades of approximately 15% zinc and 3% lead. All mineralisation in this zone is classified as Indicated resources.
Mining
Azure has prepared a trial mining plan and schedule for the Tunnel D HG zone. Tunnel D is a level drive approximately 250 metres in length which traverses high-grade, zinc-rich mineralisation along the drive.
Mining studies indicate that this massive sulphide mineralisation can be extracted at a production rate of at least 100 tonnes per day with the option of mining at a higher rate if additional processing capacity becomes available.
Selective mining by the room and pillar method will ensure maximum recovery of the massive sulphide ore while minimising dilution. Mechanised underground haulage will transport ore along Tunnel D to surface to be loaded on trucks for transport to the processing facility.
Processing
Azure has entered into a toll treatment agreement to process Oposura ore through the San Javier sulphide flotation plant. The San Javier plant has recently been fully refurbished and has a rated throughput of 100tpd. The plant is located approximately 200km by highway from Oposura.
Metallurgical testwork confirmed excellent recoveries into separate zinc and lead-silver concentrates with very low levels of impurities. Processing at the San Javier plant is expected to achieve industry benchmark grades of +53% zinc in the zinc concentrate and +60% lead and +2,000g/t silver in the lead concentrate.
In addition to San Javier, there are several other sulphide flotation processing facilities within trucking distance of Oposura, which provides Azure optionality around additional toll treatment possibilities.
Azure has received offtake terms from several international metal trading companies to sell its zinc and lead concentrates. Favourable commercial terms, including optionality around frequency and tonnage of concentrate delivery, payabilities and payment terms, have been offered due to the quality of the concentrates and the high level of interest expressed by traders. A decision on the preferred off-take partner will be made shortly.
Importantly, trial mining of the Tunnel D HG zone is not expected to impact on the broader economics of the full-scale, stand-alone operation currently being assessed by Feasibility Study. As determined in the mine production plan of the Scoping Study (ASX: 15 October 2018), this part of the deposit was scheduled to be mined in Years 5 and 6 of the mine life. By mining this high-grade material over the next year, Azure is bringing forward this source of cash flow by several years.
Meanwhile the Feasibility Study into full-scale production at Oposura is continuing, albeit at a reduced rate due to the study into the trial mining and processing operation taking precedence. It is now expected that the completion of the Feasibility Study and the interim PFS will both be delayed by up six months.
