Rockport, Canada – March 2, 2021 Rockport, Canada – New Age Metals Inc. (NAM) (TSX.V: NAM; OTCQB: NMTLF; FSE: P7J) (“NAM” or the “Company”) announces completion of Phase 1 of an ongoing Rh assay program on the River Valley Palladium Deposit near Sudbury, Ontario (Figure 1). Phase 1 of the Rh assay program collected 303 pulp samples from 17 mineralized intervals in 14 drill holes through the Pine Zone. The samples were selected to provide Rh data for mineralization in two cross-sections spaced 50 metres apart through the Pine Zone, located near the north end of the 16 km long River Valley Deposit (Figure 1). In addition to Rh, the samples were also assayed for gold (Au), iridium (Ir), palladium (Pd), platinum (Pt), and ruthenium (Ru). The assays were completed on 2015-2020 drill core sample pulps at the Geoscience Laboratories in Sudbury.
The new Rh data reported herein are in addition to historical data generated from drill core, channel and surface grab samples from the River Valley Deposit (Figure 2) (see also Pacific North West Capital Corp. press release dated July 26, 2011). Rh is the most valuable platinum group metal (PGM), with recent spot price highs of over $US24,000/oz Rh, nearly 18 times higher than Pt. However, Rh analyses are too costly to be performed on every drill core assay sample. Rh is reported in the current Mineral Resource Estimate for the River Valley Deposit (see NAM press release dated August 8, 2019), based on regression analysis of historical drill core and channel sample assay data for the Dana North, Dana South and Lismer Zones.
This announcement is the first report of Rh assay data for the Pine Zone.

Figure 2. Property scale geology and topography map showing location of the Pine Zone, River Valley Palladium Deposit. Also shown are the number of Rh assays for contiguous drill core samples from each mineralized zone (total = 7910). Note that the Pine Zone occurs 100 m to 250 m below surface in the immediate footwall to the Dana North Zone.
The purpose of the multi-phase Rh assay program is three-fold:
- Investigate Rh concentration and distribution trends within the River Valley Deposit;
For this study of the Pine Zone, the Rh assay values returned range from <0.00005 g/t (below the lower limit of detection) to 0.177 g/t Rh. Ten samples returned assays of equal to or greater than 0.100 g/t Rh and 50 samples returned assays higher than 0.050 g/t Rh (Table 1) (click here to view all results). The highest assay result for Ir is 0.039 g/t and for Ru is 0.013 g/t.
Compared to the other mineralized zones, the range of Rh assay values for Pine Zone appears to be most similar to Dana South Zone (Table 2).
Rh at Pine Zone was determined for 303 samples out of a total of 2443 (12%) drill core samples from that zone. The results show very strong positive correlation of Rh with the other four PGM (R2 >0.9) (Table 3), consistent with presence in the mineral phase Hollingworthite [(Rh,Pt,Pd)AsS], which has been identified in previous mineralogical studies of River Valley. Rh shows strong correlation (R2 >0.8) with copper (Cu) and moderate correlation
(R2 >0.5) with sulphur (S) (Table 3). On the other hand, Rh does not correlate (R2 = -0.015) with chromium, and therefore is not held in Cr-bearing phases (chromite).
The occurrence of Rh with sulphides and not chromite differs from other Rh-bearing PGM deposits elsewhere, and could potentially simplify metallurgical recovery processes.
- Develop a more robust regression technique to estimate Rh concentrations from Pt grades for future Mineral Resource Estimates; and
Statistical analysis indicates that Rh values for the remaining 2140 samples from the Pine Zone can be estimated on the basis of Pt values through regression analysis. Results of this study indicate that Rh concentrations are equivalent to be approximately 12% of the Pt grades.
A plot of measured Pt values versus Rh values for the 303 drill core samples from the Pine Zone and the robust simple regression line with its derived equation are shown in Figure 3.

Statistical analysis indicates that Rh values for the remaining River Valley Deposit can be estimated on the basis of Pt values through regression analysis. A plot of measured Pt values versus Rh values for all the drill core samples from River Valley and the robust simple regression line with its derived equation are shown in Figure 4. Phase 2 of the Rh assay program plans to analyse samples from the Dana South and Lismer Zones in 2021.

- Investigate potential of Rh as payable metal at River Valley
In order to complete the study, subsequent phases of work will take samples of PGM mineralized intervals from additional mineralized zones to establish and confirm the spatial distribution of
Rh throughout the River Valley Deposit. Specifically, the mineralized zones selected to be studied next are Dana South and Lismer. Rh recovery testwork will be included in future metallurgical studies, in order to determine whether Rh could be a payable metal for a potential PGM mining operation at River Valley.
Rh is the rarest and most valuable of the PGMs. The main use for Rh is in catalytic converters designed to clean vehicle emissions. This metal is particularly effective in cleaning nitric oxide emissions from internal combustion engine vehicles. The majority of Rh is produced as a by-product of platinum mining in South Africa. South Africa is the world’s largest producer of Rh (~80%), followed by Russia (~10%), Zimbabwe (~5%), Canada (~2%) and the USA (~2%).
The global average mineral resource/reserve grade is 0.281 g/t Rh, with the lowest reported mineral resource/reserve grade of 0.010 g/t Rh and the highest reported mineral resource/reserve grade of 0.381 g/t Rh (source: S&P Global, 2020).
Assay Procedures & QA/QC
Drill core pulps were selected by NAM geologists from PGM-Cu sulphide mineralized intervals in Pine Zone holes drilled in 2015, 2016, 2017 and 2020. The pulp samples were delivered directly to Geoscience Laboratory in Sudbury, Ontario for sample preparation and assay analyses. Gold, iridium, palladium, platinum, rhodium and ruthenium were assayed by 30 g nickel fire assay with ICP-MS finish (IMP-200; ISO/IEC 17025 Accredited). Blanks and blind certified reference material (standards) samples were inserted at regular intervals for assay with the core samples as part of NAM’s rigorous Quality Assurance/Quality Control program.
About the River Valley Palladium Project
The details of the updated Mineral Resource Estimate (MRE) and Preliminary Economic Assessment (PEA) were announced in the press release dated August 9, 2019 and are described on NAM’s website. The pit constrained Updated Mineral Resource Estimate formed the basis of the PEA. At a cut-off grade of 0.35 g/t PdEq, the Updated Mineral Resource Estimate contains
2.867 Moz PdEq in the Measured plus Indicated classifications and 1.059 Moz PdEq in the Inferred classification. The PEA is a preliminary report, but it demonstrates that there are potentially positive economics for a large-scale mining open pit operation, with 14 years of palladium production. Refer to the NAM website (www.newagemetals.com) for details.
