Corporate and Project Update on the Emily Manganese Project


TORONTO, ON / ACCESSWIRE / December 21, 2021 / Nevada Silver Corporation (“NSC” or the “Company”) (TSXV:NSC) is pleased to provide an update on its 100% owned subsidiary North State Manganese Inc (“North Star”) and the Emily Manganese Project (“Emily”). Emily is in the Cuyuna Iron Range, Crow Wing County, Minnesota and was the subject of a June 2020 NI 43-101 mineral resource estimate by Barr Engineering Company (Table 1)1.


Review of NI 43-101 resource drill data highlights high-grade intersections

North Star recently commissioned a review of drilling and other technical data contained within the Barr Engineering mineral resource estimate. A number of high-grade drill intersections were identified within thicker zones of mineralization2, including:

  • Drill hole VC-01-11: 33.68 meters from 70.56 meters @ 16.93% Mn
    • Including 8.99 meters @ 34.58% Mn; and
    • Including 1.07 meters @ 50.10% Mn
  • Drill hole AC-01-11: 36.88 meters from 135.02 meters @ 9.98% Mn
    • Including 7.47 meters @ 29.48% Mn; and
    • Including 1.52 meters @ 43.00% Mn
  • Drill hole AC-02-11: 19.5 meters from 70.1 meters @ 18.5% Mn
    • Including 8.84 meters @ 32.94% Mn; and
    • Including 6.10 meters @ 39.33% Mn; and
    • Including 3.05 meters @ 45.74% Mn
  • Drill hole AC-04-12: 9.0 meters from 137.2 meters @ 17.6% Mn
    • Including 4.47 meters @ 24.47% Mn (Figure 1)

A summary of intersections of the drill holes included in the Barr Engineering NI 43-01 Technical Report is contained in the appendix.


Historical metallurgical work at Emily was undertaken by Montana Tech, of the University of Montana, Coleraine Minerals Research Laboratory, Hazen Research, Inc., Outotec, USA, and Kemetco Research, Inc. North Star is presently updating the metallurgical tests performed by Kemetco on samples from the Emily deposit. Historic samples were successfully upgraded to produce MnCO3 (manganese carbonate), EMD (electrolytic manganese dioxide – MnO2) and EMM (electrolytic manganese metal – Mn) (Figure 2).


Emily is well located near regional industrial centers (iron mining and processing) with major transportation linkages (road, rail and shipping). In addition to its ownership and management rights, North Star also has exclusive surface leases and operational rights to the structures and facilities located at Emily (Figure 3).

Building A High-Purity Manganese Supply Chain In North America

It is North Star’s ultimate aim is to produce high-purity manganese products for North American technology and energy markets. There are currently no producing manganese mines in the USA or Canada, and manganese is on the strategic metals list in both countries.

Manganese is a critical component to the lithium-ion battery (Li-B) supply chain, being used in two of the most prominent batteries in production, i.e., Nickel Lithium Manganese Oxide (LMO) and Manganese Cobalt (NMC) batteries. Within LMO batteries, there is approximately 61% manganese in the cathode, while in the NMC battery, manganese constitutes 20-30% of the total cathode material3. BASF recently unveiled ambitious plans to boost investment in battery cathode active materials (CAM), including a new family of manganese-rich products. Volkswagen and Tesla have each announced plans to mass produce a new battery that requires a high proportion of manganese with no cobalt (Tesla at ~ 33% Mn, and VW over 50% Mn)4.

“We believe the high-purity manganese market will be driven by the demand for these specialized products over the next decade” commented NSC’s CEO Gary Lewis. “This is line with the North Star’s aspiration to capture significant value of the supply chain for high-purity manganese products, from raw material extraction and product upgrading, through chemical processing and high-purity manganese sales in the North American marketplace.”


Corporate update

The Company is continuing to assess options for the commercialization of the Emily Manganese Project to the benefit of NSC shareholders. Alternatives under investigation include potential joint venture arrangements and / or the spinning-out of North Star into a standalone listed entity. NSC will provide a further update early in the new year.
