Osino Announces Filing of Amended and Restated Pre-Feasibility Study Technical Report for Its Twin Hills Gold Project, Namibia

VANCOUVER, British Columbia, Oct. 26, 2022 (GLOBE NEWSWIRE) -- Osino Resources Corp. OSI (FSE:RSR1) OSIIF ("Osino" or "the Company") is pleased to announce that it has filed an amended and restated pre-feasibility study technical report entitled, "Amended and Restated Pre-Feasibility Study of the Twin Hills Gold Project, Namibia, NI 43-101 Technical Report" dated effective September 6, 2022 and signed October 25, 2022 (the "PFS Technical Report") for its pre-feasibility study announced in the Company's news release dated September 6, 2022, which amends and restates the initial pre-feasibility study recently filed on October 21, 2022 (the "Initial PFS"). The PFS Technical Report updates and replaces the Initial PFS with the most current information to better reflect the status of the Twin Hills Gold Project and is prepared and filed in accordance with National Instrument 43-101—Standards of Disclosure for Mineral Projects ("NI 43-101").

The amended and restated PFS Technical Report corrects minor editorial mistakes as well as the content of Section 22 where an outdated analysis had been inserted in the Initial PFS. The technical and economic results of the pre-feasibility study as summarized in the Company's news release dated September 6, 2022 remains valid and unchanged.

As previously reported, the PFS Technical Report is based on 2.15 Moz in reserves, outlining a 13-year mine life with an average annual production of 169 koz at all-in sustaining costs of US$930/oz in the first 10 years of operation. The initial capital cost of the project is estimated at US$375M. Osino has initiated engineering studies aimed at optimizing the process flow sheet and reflecting potentially significant capital cost savings which were identified while completing the pre-feasibility. Osino intends on completing and publishing a definitive feasibility study on the Twin Hills project during Q2 of 2023.

For additional information, please refer to the PFS Technical Report available on the Osino website and filed on SEDAR under the Company's profile at www.sedar.com, which is an update of the Initial PFS and contains the most current comprehensive technical information and reflects the Company's news release dated September 6, 2022.
