Positive Preliminary Economic Assessment for the River Valley PGM Project, Sudbury, Ontario, Canada
June 27th, 2019 – TheNewswire – Rockport, Canada – New Age Metals Inc. (NAM) (TSX.V: NAM; OTCQB: NMTLF; FSE: P7J.F) Harry Barr, Chairman & CEO, stated; “We are pleased to update our shareholders and interested parties as to the results of the initial Preliminary Economic Assessment (PEA) for the company’s 100% owned River Valley PGM Project in Sudbury, Ontario Canada. The PEA has been developed by various independent consultants – P&E Mining Consultants Inc. (P&E) was responsible for the open pit mining, surface infrastructure, tailings facility, and project economics; DRA Americas Inc. (“DRA”) was responsible for all metallurgical test work and processing aspects of the Project; and WSP Canada Inc. (“WSP”) was responsible for the Mineral Resource Estimate. The PEA demonstrates positive economics for a large-scale mining open pit operation, with 14 years of Palladium and Platinum production.”
Go-Forward Plan: In order to enhance the Project, the PEA has outlined a phased work approach to completing a Pre-Feasibility study. This includes advanced metallurgical testing to improve / confirm process recoveries and more accurately estimate concentrate grades, geotechnical logging of drill core, with new geotechnical holes to create a 3D geomechanical block model and estimate pit wall angles, hydrogeological studies that will estimate water inflows to the open pits and generate a site water and management plan. The Pre-Feasibility study will update the Project study to a higher level of precision.
NAM plans to continue to improve the River Valley Project’s value proposition by drill testing geophysical anomalies found during the 2018 geophysics campaign, continuing the geophysical program throughout the 16 kilometres of the contact mineralization adding significant potential to find new deposits, drilling near the defined open pit shells to increase the mine life, drilling deeper to test the open-ended Deposit at depth, and re-assaying existing drill core for Rhodium in order that Rhodium may be added to the Project’s metal suite.
Technical Report: For readers to fully understand the information in this news release, they should read the PEA Technical Report in its entirety which the Company expects to file in accordance with NI 43-101 within 45 days from the date of this news release on SEDAR (www.sedar.com) and it will also be available at that time on the New Age Metals website, including all qualifications, assumptions and exclusions that relate to the PEA. The Technical Report is intended to be read in its entirety, and sections should not be read or relied upon out of context.
The PEA parameters are summarized in Table 1.
(*) Cautionary statement NI 43-101: The PEA was prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”). Readers are cautioned that the PEA is preliminary in nature. It includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. All currency is stated as CDN$ unless stated otherwise.

River Valley Project Site Plan
See the image below that shows a site plan from the River Valley PEA. The map shows all of the 14 open pits that have been used in the engineering design of the Project as well as the proposed process plant site, low-grade stockpile, waste rock storage facilities, tailings storage facility and site infrastructure.
The pit constrained Mineral Resource Estimate which formed the basis of the PEA, is set out in Table 5 and was prepared by WSP under the supervision of Todd McCracken, P. Geo., an “Independent Qualified Person”, as defined in NI 43-101. The effective date of this Mineral Resource Estimate is January 9, 2019. The Mineral Resource database contains 710 boreholes with 106,554 assays records in the database, and 2,642 surface channel samplings. The Mineral Resource Estimate update was completed on the Dana North, Dana South, Pine, Banshee, Lismer, Lismer Extension, Varley, Azen, Razor, and River Valley Extension Zones, using the ordinary kriging (OK) methodology on a capped and composited borehole dataset consistent with industry standards. Validation of the results was conducted thought the use of visual inspection, swath plots and global statistical comparison of the model against inverse distance squared (ID2) and nearest neighbour (NN) models.
Table 5: Pit Constrained Mineral Resource Estimate for River Valley PGM Project – Effective January 9, 2019.
- CIM definition standards were followed for the Mineral Resource Estimate.
- The 2018 Mineral Resource models used Ordinary Kriging grade estimation within a three-dimensional block model with mineralized zones defined by wireframed solids.
- A base cut-off grade of 0.35 g/t PdEq was used for reporting Mineral Resources in a constrained pit and 2.00 g/t PdEq was used for reporting the Mineral Resources under the pit.
- Palladium Equivalent (PdEq) calculated using (US$): $950/oz Pd, $950/oz Pt, $1,275/oz Au, $1,500/oz Rh, $2.75/lb Cu, $5.25/lb Ni, $36/lb Co.
- Numbers may not add exactly due to rounding.
- Mineral Resources that are not Mineral Reserves do not have economic viability
- The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
Mining and Processing
The PEA is preliminary in nature, and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the Preliminary Economic Assessment will be realized.
The River Valley Project is expected to be mined by a contractor. Initial mining will occur at the northwest end of the Deposit, close to the proposed process plant site. A series of 14 open pits will be mined, and will progress in a southeasterly direction. Pit numbers 1 to 4 contain the bulk of the mineralized process plant feed.
Annual process plant feed of up to 6 Mtpy (0.5 Mtpm) is planned, at an average strip ratio of 3.6:1 over the life-of-mine. It is anticipated that a fleet of 221 t haul trucks, 29 m3 excavators and 254 mm diameter hole rotary drills will be utilized, following industry standard conventional open pit mining techniques.
The process plant is designed to produce a single saleable PGM concentrate using conventional sulphide flotation techniques. The concentrate will be trucked to a smelter/refinery in the Sudbury area.
The Run-Of-Mine (ROM) feed from the mine will be crushed in a single primary jaw crushing stage prior to the grinding circuit. The crusher discharge will be conveyed to a live stockpile, which will provide an operating buffer between the crushing and grinding circuits.
The grinding circuit will consist of a SAG mill in closed circuit with a pebble crusher and two ball mills in parallel.
The process plant design considers three stages of cleaner flotation and is designed to process 21,920 tpd (6.0 Mtpy) of ROM feed.
The flotation circuit configuration and design are based on the locked cycle tests conducted by SGS Canada in 2013.
Concentrate and tailings products will be dewatered using high-rate thickeners and the concentrate will be further dewatered by conventional plate and frame vacuum filtration.
Process water will be recovered from the concentrate and tailings thickener overflow. Raw water is assumed to be sourced from the local environment and will be used as makeup water. It is assumed that 10% of the raw water requirement will be recycled from the tailings pond.
Conventional tailings deposition techniques will be utilized.
A 230 kV transmission line is located passing through the village of Warren, approximately 22 km from the Project. A 115 kV transmission line passes through the village of Field, located approximately 15 km to the east of the Project. It is assumed that electrical power will be provided by the local utility via either of these overland power lines. Diesel generators will be used to supply emergency power.
Project Enhancement Opportunities
The PEA demonstrates that River Valley has the potential to be economically viable. The PEA also outlines several opportunities to enhance Project value. Additional opportunities include:
