Clarification of Disclosure Respecting: Preliminary Economic Assessment Commences at Diba Gold Project in Western Mali

DIDCOT, April 17, 2020 - Altus Strategies Plc (AIM:ALS & TSX-V:ALTS), the Africa focused project and royalty generator, at the request of IIROC, hereby clarifies certain disclosure in its news release entitled "Preliminary Economic Assessment Commences at Diba Gold Project in Western Mali" dated April 16, 2020 (the "News Release").

The various references in the News Release to a "historical resource" and "resource update", including the statement from Altus' Chief Executive that "the historic resource alone may already represent a very significant opportunity for Altus to create substantial near-term value", could be interpreted as treating the historical resource estimate for Diba as a current mineral resource which is not permitted by National Instrument 43-101 "Standards of Disclosure for Mineral Projects" of the Canadian Securities Administrators ("NI 43-101"). That was not the Company's intention and it clarifies that it is not treating the historical estimate as a current mineral resource.

The cautionary disclosure required by NI 43-101, namely, that a Qualified Person has not undertaken sufficient work to classify the historical resource as a current mineral resource and that the Company is not treating the historical resource as a current mineral resource was made under "Diba Project: Historical Resource" but was not (and is now hereby deemed to be) stated under the "Highlights" in the News Release proximate to the historical resource amounts as required by CP 43-101.

The News Release makes several references to Diba's proximity to the multi-million ounce Sadiola gold mine and the multi-million ounce Yatela former gold mine. Cautionary language stating that the "mineralization hosted on these properties is not necessarily indicative of mineralization hosted at Diba" should have appeared next to (and is now hereby deemed to be) such references.

Finally, the News Release makes reference to "orebody" and "low mining strip ratio". Under NI 43-1010, the term "ore" may only be used in connection with mineral reserves. Furthermore, the "potential for a low mining strip ratio" is not supported by a preliminary economic assessment, preliminary feasibility study or feasibility study. The references to "orebody" and "low mining strip ratio" are hereby retracted.
