Bacanora Minerals Announces Completion of NI 43-101 Pre-Feasibility Study for Production of 35,000 TPA Lithium Carbonate at Its Sonora Lithium Project, Mexico
(firmenpresse) - CALGARY, ALBERTA -- (Marketwired) -- 03/02/16 -- BACANORA MINERALS LTD. ("Bacanora" or the "Company") (TSX VENTURE: BCN)(AIM: BCN), the London and Canadian listed lithium company that is developing the Sonora Lithium Project(1) ("Project") in northern Mexico ("Sonora"), is pleased to announce positive results of a Pre-Feasibility Study ("PFS") (prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101")) for the development of a mine and lithium carbonate ("Li2CO3") processing facility at Sonora. The PFS estimates a Project pre-tax Internal Rate of Return ("IRR") of 29% (post-tax 25%) and an associated Net Present Value ("NPV") of US$776M, (post-tax US$542M) at an 8% discount rate. These results highlight the strong economic potential of producing up to 35,000 tonnes per annum of battery grade Li2CO3 at Sonora. In addition, Sonora has the potential to produce up to 50,000 tonnes per year of potassium sulphate ("K2SO4"), for sale to the fertiliser industry.
With an Indicated Mineral Resource estimate of 5.0 million tonnes ("Mt") of lithium carbonate equivalent ("LCE")(2) and an Inferred Mineral Resource of 3.9 Mt of LCE, Sonora is one of the world's larger known clay lithium deposits. Following the results of the PFS, management is focused on advancing the development of Sonora and will immediately commence a Feasibility Study ("FS"), as it looks to bring the project into production to satisfy expected strong growth in demand for lithium from fast growing sectors, such as electric vehicles and energy storage.
Highlights of Sonora PFS:
Two phase open-pit mine and lithium carbonate processing facility with a life of over 20 years
The PFS demonstrates the attractive economics of Sonora and key findings are shown in the table below:
Table 1: Key Results
Peter Secker, CEO of Bacanora, commented, "With a Pre-Tax NPV of US$776M and an IRR of 29%, the PFS supports that Sonora is well placed to become one of the next major lithium producers, supplying fast growing industries, such as electric vehicles, smartphones, and energy storage. The next key step in the development of Sonora is a Feasibility Study, which is fully funded and expected to be completed in Q1 2017."
"In tandem with the FS, we will be seeking additional offtake partners for Sonora's lithium carbonate, which will represent a major milestone as we focus on commercialising the project. With recent lithium price increases in the Asian market we believe that Sonora is a highly compelling project with which to generate value for shareholders. I look forward to providing further updates on our progress as we focus on transforming Bacanora from an exploration and development company into the next significant producer of lithium carbonate."
Project Introduction
The Sonora Lithium Project is located in northern Sonora State, Mexico, approximately three hours' drive north east of the state capital of Hermosillo, a city of approximately 700,000 people. Access to the site is by road from either Hermosillo or the US border town of Agua Prieta. The project has access to significant support infrastructure including paved roads, process water and high voltage power.
The Sonora lithium property hosts one of the world's larger known clay lithium deposits. The polylithionite and hectorite mineralisation is hosted within shallow dipping sequences, outcropping on surface. A mineral resource estimate was prepared by SRK Consulting (UK) Limited in accordance with NI 43-101 with an effective date of November 19th, 2015. The following tables present the summary of current lithium resources for the project.

Mining Operations
The mining operation for the project is planned as an open-pit operation using conventional truck/shovel mining methods. Mining operations will be carried out with hydraulic excavators and haul trucks and an ancillary fleet of dozers, graders and water trucks. The Mineral Reserve estimate was prepared by Independent Mining Consultants Inc. in Tucson, Arizona. The Reserve estimate used an ore recovery factor of 100% and a mining dilution rate of 10% at an average dilution grade of 0%. The Mineral Reserve stripping ratio is approximately 5.4:1.
Table 4: Probable Mineral Reserves: (Cut-off grade of 0.12% Li)
For the Stage1/Stage2 mining design a total of 50 Mt of ore at a grade of 3,525 Li ppm and 1.49% K and a stripping ratio of 3.1:1 will be mined over the initial 20-year mine life.
Processing
Metallurgical testwork for the PFS was carried out at SGS Lakefield Laboratories in Canada and process engineering and design for the process plants and infrastructure was completed by Ausenco Limited ("Ausenco"). The processing plant design comprises a pre-concentration stage comprising scrubber, hydrocyclones and reverse flotation to produce an initial concentrate prior to roasting. The concentrate is subsequently heated in a kiln, at approximately 1,000 degrees Celsius, with gypsum to produce a lithium sulphate product. This sulphate material then undergoes hydrometallurgical treatment, filtration, cleaning, precipitation and packaging, to produce a 99.5% Li2CO3 final battery grade product. The integrated plant has been designed to initially process 1.4 Mt of ore per year, during the first two years of the project, subsequently increasing to some 2.7 Mt per year subsequent to year three.
The plant design also includes a circuit to produce 50,000 tonnes per annum of commercial grade K2SO4 through a series of evaporation, precipitation, filtration and packaging stages. The plant has the potential to produce up to 50,000 tonnes per annum of this material, which could be sold as a fertiliser grade product for domestic consumption in Mexico.
Capital Costs
The initial mining capital costs include an initial fleet comprising a 12 cubic metre backhoe excavator and three 90-tonne haul trucks, building up to sixteen haul trucks at full production. In addition, there is an ancillary mobile fleet including dozers, graders and front end loaders. The initial capital cost of the equipment is estimated to be US$19M.
The metallurgical processing facility capital cost estimate is based on an on-site processing plant comprising all new equipment, to produce battery-grade lithium carbonate.
The capital cost estimates for process plant, infrastructure, Tailings Management Facility construction, Engineering, Procurement, and Construction Management ("EPCM") fees, owner's costs and general administration costs were determined by Ausenco.
Table 5: Construction Capital Costs (rounded to nearest US$'000)
The LOM sustaining mining and processing capital requirement is approximately US$111M.
Operating Cost Estimate
The mining and processing operating costs are for an operation achieving average annual production of approximately 35,000 tonnes of battery-grade, 99.5% Li2CO3. The estimated average operating cost for the mine, primary and secondary processing facilities are presented below.
Table 6: Project Operating Costs
Cash Flow Analysis
The project is currently estimated to have a short payback period of five years. Cash flows are based on a 100% equity funding basis and the economic analysis indicates a pre-tax Net Present Value, discounted at 8%, of approximately US$776M as shown below and IRR of approximately 29%. Post tax the NPV is approximately US$542M and IRR 25%.
Table 7: Sensitivity Analysis
Base case LOM revenue is estimated at US$4 billion, with an EBITDA of approximately US$2.7 billion. An average MEX$/US$ exchange rate of 17.1:1 has been used over the life of the mine.
Market Review
SignumBox (Chile) has provided a lithium carbonate price forecast in the range of $5,500 to $6,000 per tonne. Recent data from Asia indicates that spot pricing is currently above $6,000 per tonne.
The current dominant lithium battery technologies such as lithium cobalt oxide, lithium manganese oxide and lithium nickel manganese cobalt oxide typically use lithium carbonate as the main source of lithium cathode material and battery cathode demand is the fastest growing segment of the lithium market. K2SO4 is used as a fertilizer product and can sell in the range of $600-$700/t.
Community and Environment
As part of the Company's Environmental Management Programs, initial site sampling and monitoring commenced in Q3 2015. Local environmental consulting groups are being used to prepare the Manifestacion de Impacto Ambiental, which is scheduled to be lodged with the appropriate local authorities in Q3, 2016. In addition, the Company has designed an active programme to engage with the local communities living within the project area.
Project Timetable
Over the next 18 months the Company will continue to progress the Sonora Lithium Project through the project development stages, with the intention of completing a Feasibility Study by Q1 (calendar) 2017. The following preliminary indicative timetable is proposed:
