Los Andes Copper Ltd. Receives Updated Rougher Flotation Assessment Results for the Vizcachitas Project

Perth, Australia (ABN Newswire) - Cyprium Metals Limited (ASX:CYM) is pleased to announce progress at its Nifty Copper Project. Since taking control of the site on the 30th March 2021, the Company has made significant progress towards establishing itself as an Australian copper producer.

Project Progress

Drilling programmes continue to upgrade mineral resource confidence, close the gaps in resource and to target extensional areas of the mineralised formation. Currently the Phase 2 reverse circulation ("RC") drilling programme is being completed in the South East of the Nifty open pit. There are now approaching 4,000 samples from this programme that have not had assays returned. Further to this, there remain over 8,000 samples for which assays have not been returned from the +16,000 metre South West drilling programme that was completed in November. The RC drilling continues to intersect ore grade intervals and following receipt of assays, will be included in the mineral resource model for the design and scheduling of the planned Nifty open pit. Once all of the assays have been received, a follow up Phase 2 drilling programme will be planned in the South West of the Nifty open pit and a follow up Phase 3 drilling programme in the South East of the Nifty open pit will be planned. This is very positive for the Nifty Copper Project as there are further copper tonnes to be added to the project copper inventory but also potentially delays final mine designs and schedule progress.

Design and scheduling of the open pit continues based on the recently released Nifty Mineral Resource. The current pit envelope does not include any increase in resources from the results of our drilling programmes as mentioned above. These designs will be sufficient to be included in the Restart Study and for the Finance process but will not be final until the resource is re-estimated during the first quarter of 2022 at the earliest.

Engineering design of the SX-EW plant and heap leach pads is nearing completion. The new heap leach pads construction and design detail is required for the Works Approval submission so that construction activities can commence. Concurrent with the design process, tenders are being issued for the purchase and supply of long lead items.

Metallurgy check column test work continues. Four columns have been undertaken, including the fourth column which is a 6-metre column to match operating conditions. Results have been as expected and optimisation of reagent consumptions continues. When this round of work has been completed, a number of follow up tests will be conducted to further optimise the operating parameters. Reporting to the market on these results will be done once the test work has been completed on the residues and the reports compiled. There will also be follow up tests undertaken on core and sonic drill samples. In addition, there are 550 sonic samples yet to be assayed that have been obtained from around the site to test for the location of stockpiled oxide material.

A consultant has been engaged to firstly, build a complete mass balance and copper recovery cathode software model for the project based on the metallurgical parameters and then secondly, to design and build a metallurgical accounting system for the project so that it is ready upon the commencement of plating copper metal at Nifty. This work is well advanced.

Finance process will commence once the Restart Study is finalised. Outstanding items are schedules, with allowance for an extended approval timeline, and final costs on a number of items including civil construction elements of the heap leach pads and associated crushing infrastructure.

Government Approvals are required in the new areas of the project. As a State Agreement tenement there is a Ministerial approval required to amend the project size and life. There is a requirement for clearing permits for the new clearing required for the new heap leach pads and an amendment to a current approval for the extension to the waste dump. There is an amended Mining Proposal required for the restart of the pit, pads and SX-EW which includes submission of a Project Management Plan and a Mine Closure Plan. There is an amended Works Approval required for the restart of the SX-EW and the new heap leach pads and an amendment to the Water Licence for the change in water extraction method from underground. There are also a number of smaller permits required around the restart of the mining operation, that require reactivation or renewal.

The process of obtaining these approvals is well advanced, having conducted initial meetings and workshops, document compilation is nearing completion. The first submission of the required proposals for the clearing of native vegetation for the waste dump and the new heap leach pads has already been lodged. This is the first stage in the approval process, with management and consultants preparing submissions for the subsequent approvals. Progress is being hampered by shortage of personnel and availability of external specialists to complete the various reports that are required to lodge approval documentation. The expectation is that all documents will be lodged by the first quarter 2022.

Government staff have been very helpful in assisting CYM in making sure that the required proposals contain all that is necessary for an efficient approval process but the various departments, like the whole WA resource industry are suffering from understaffing, and it is expected that the timelines to approval will be longer than originally anticipated. Site visits have been undertaken and the learnings from these visits have been helpful in ensuring that the proposal documentation is complete.

During CYM's tenure, staff have rectified a number of legacy issues at the site that have been paid little attention for some years and site crews have managed to rectify a number of areas that have previously been raised by the regulators. Further, the site crew have been cleaning and collecting years of rubbish and waste to centralised locations and are now going through a process of scrap, recycle or disposal for these waste streams. These waste streams also include chemicals and reagents that are expired and have been on site for many years. The sale of unwanted or scrap equipment has been commenced with sold items already been removed from site. This process will continue for some time due to the volume of equipment, materials, scrap and rubbish that has built up while Nifty was operational.

Refurbishment of the oxide crushing circuit and SX-EW plant has begun. Currently the plant is being stripped down and assessed for refurbishment on an item-by-item basis. The items to be refurbished are then despatched to the required refurbishment location for the work to be undertaken whether on site, in Perth or Kalgoorlie or another specialist location. As an example, the EW electric rectiformer has already been delivered to the workshop in NSW for its refurbishment. The items are also matched with any parts or spares in stock in the warehouse.

The accumulation process as described in the site clean-up section has also delivered a significant number of new and "useable" items back into the store, which had previously been located in sub or "squirrel" stores around the site. Stores staff are still in the process of cataloguing all these items for which they lack sufficient centralised storage areas for. As items are declared not required and sold it creates space to bring in items from those other areas.

Accommodation Camp refurbishment has begun with the eastern side of the camp undergoing a refurbishment process first. The refurbishment will bring the accommodation standard to be aligned with Cyprium's attraction and retention requirements for site personnel. Once the eastern refurbishment is complete the western refurbishment will commence. The dry mess is undergoing a refurbishment process concurrently with the eastern side of the camp.

Managing Director Barry Cahill commented:

"The Cyprium team continues to kick goals on its way to producing copper metal plate at Nifty. Drilling success continues, design process is proceeding, and we have commenced refurbishment of the project. Despite our best efforts and the exceptional progress that we have made in 8 months, there are pressures being felt throughout the mining industry. These additional pressures are primarily due to labour shortages, increasing costs, COVID related impacts and long timelines that have impacted on our original projections.

These same factors are also impacting on processing times for regulatory approvals. Consequently, we have been forced to reschedule our forecast project timelines, with the commencement of new construction activities now expected in September 2022, following regulatory approvals. Copper metal production at Nifty will now commence by the second half of 2023. As usual for our team, we will aim to commence copper production at the earliest opportunity."
