Amur Minerals Corporation ('Amur' or the 'Company'), the nickel-copper sulphide exploration and resource development company focused on the far east of Russia, is pleased to announce RPM Global's ('RPM') 25 June 2021 update to the Mineral Resource Estimate ('MRE') for its 100% owned Kun-Manie project ('Kun-Manie').

The MRE update includes all existing drill and trench results. The resource is contained within three deposits identified as Maly Kurumkon / Flangovy ('MKF'), Vodorazdelny ('VOD') and Ikenskoe / Sobolevsky / Kubuk ('ISK'). Based on a 0.3% nickel equivalent cut-off grade ('COG'), the global JORC ore tonnage has increased by 19.2 million tonnes ('Mt') (12.4%) to 174.3 Mt, by 156,000 nickel tonnes (13.5%) to 1.31 Mt of nickel (averaging 0.75% nickel) and by 53,000 copper tonnes (16.6%) to 372,000 copper tonnes (averaging 0.21% copper). Of the global resource available for utilisation in the development of a JORC Mining Ore Reserve ('MOR'), only Measured and Indicated categories qualify for inclusion.

The global Measured plus Indicated resource now consists of 148.3 million ore tonnes containing 1.11 Mt nickel (averaging 0.75% nickel) and 0.31 million tonnes copper (averaging 0.21% copper). An additional 29.4 Mt Inferred ore tonnes averaging 0.69% nickel (204,000 nickel tonnes) and 0.20% copper (58,000 copper tonnes).

Byproduct metal content have been estimated for cobalt, platinum, palladium, gold and silver, but are not reported herein as the nonbinding offtake payable terms for the by-product metals is limited. RPM has stated that in-fill drilling of the existing Inferred resources could expand the Measured and Indicated resource, and the limits of the mineralisation have not been fully defined in the down dip directions and in other areas where limited drilling indicates the presence of mineralisation within the licence boundary limits.

Robin Young, CEO of Amur Minerals, commented: 'The newly released JORC resource estimate on the Kun-Manie nickel copper sulphide deposit is a major step in the update to all future study work associated with western market and funding. Not only has the resource been expanded but the resource categories suited for the definition of JORC mining reserves have also been increased by as much as 25%. Copper will serve to provide additional revenues which had been completely excluded in our February 2019 operational base case. That base case was then comprised of a single nickel only payable concentrate sold into one of the three major nickel consuming nations of China, Japan and South Korea. The addition of the copper revenue will likely have a material impact on the results presented in the independently audited February 2019 PFS.'

Mineral Resource Statements - Competent Person's Criteria

Amur Minerals Corporation reports resources based on JORC 2012 standards. This requires that the Mineral Resource Estimates ('MRE') be independently compiled from audited information attained using best industry practices. AMC has engaged RPM Global ('RPM') as the qualified company responsible completion of this important and mandatory task to assess its Kun-Manie nickel copper sulphide project located in the far east of Russia.

RPM have conducted the mandatory site visit allowing it to audit the Company's field procedures, sample handling and preparation techniques, analytical procedures, results and Quality Assessment / Quality Control ('QAQC') systems (check assaying) that it implements. RPM confirms that AMC has undertaken its exploration programmes using industry best practices enabling AMC to issue this update to the global MRE within the boundary limits of the Kun-Manie detailed exploration and mining property limits and that it is reported in accordance with JORC (December 2012) standards.
