Orvana Announces Filing of Amended Technical Report

Toronto, Ontario, March 15, 2022 - Orvana Minerals Corp. (TSX:ORV) (the “Company” or “Orvana”)

announces that it has filed an amended technical report entitled "National Instrument 43-101 Technical Report

for the Don Mario Property, Eastern Bolivia" (the "Amended Technical Report") and dated March 15, 2022. The

Amended Technical Report addresses comments raised by the Ontario Securities Commission (the "OSC") in

the course of its continuous disclosure review.

On December 29, 2020, the Company filed a technical report effective September 30, 2020, on the Don Mario

oxide stockpile project, located on the Don Mario Property (the "Stockpile Technical Report"). On December

29, 2021, the Company filed a technical report effective September 30, 2021, on the tailings reprocessing

project, also located on the Don Mario Property (the "Tailings Technical Report"). Both projects on the Don

Mario Property were reported independently as the mineral resource base are not connected.

On January 30, 2022, the Company announced that OSC staff advised that under the definition of a technical

report in National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), there can be

only one current technical report in respect of a property. OSC staff also identified certain other deficiencies in

the Stockpile Technical Report and Tailings Technical Report related to disclosure that is required under several

Items in F orm 43- 101F1. The Amended Technical Report resolves these matters by, among other things,

merging the disclosure contained in the Stockpile Technical Report and the Tailings Technical Report.

Mineral Resources and Reserves estimates as of September 30, 2021 of the Don Mario Property remain

unchanged, as previously disclosed in the Annual Information Form for the year ended September 30 , 2021.

The Company, together with qualified persons, have addressed the comments from OSC Staff and all sections

are updated in the document filed on SEDAR. The Amended Technical Report is available on SEDAR at

www.sedar.com and on the Company's website at www.orvana.com.

The Amended Technical Report was prepared by Caracle Creek International Consulting Inc . (Ontario,

Canada). The qualified persons, as defined under NI 43-101, are Scott Jobin-Bevans (PhD., PMP, P.Geo.) and

Michael Gross (MSc., P.Geo.) . Dr. Jobin-Bevans and Mr. Gross have reviewed and approved the technical

content of this news release.
