Regulus Announces US$5.0 M Investment From Osisko Gold Royalties

VANCOUVER, Oct. 14, 2022 - Regulus Resources Inc. ("Regulus" or the "Company", TSX-V: REG, OTCQX: RGLSF) is pleased to announce the completion of a US$5 million investment (the "Investment") from Osisko Gold Royalties ("Osisko") in exchange for a net smelter return ("NSR") ranging from 0.125% to 1.5% on certain claims of the Company's AntaKori project ("AntaKori"), as well as a right (currently held by Regulus) to buy-back a 1% NSR from a third party on certain claims of AntaKori. Proceeds from the Investment will be used for exploration activities at AntaKori and for general corporate purposes. This Investment is the second completed by Osisko on the AntaKori project. The first was the strategic partnership between Regulus and Osisko announced on October 1, 2020 (the "Strategic Partnership").

Highlights

• The Investment represents a significant financing in challenging capital markets.
  • No incremental royalties on the claims where Osisko acquired a 0.75-1.5% NSR through the Strategic Partnership in 2020, where the majority of current NI 43-101 resources lie.
  • Deal structured such that the NSR's issued in relation to the Investment together with existing outstanding royalties will not exceed 1.5%.
• Brings cash into the treasury with no dilution to shareholders.
• The Investment allows Regulus to continue to advance exploration activities on the AntaKori project and maintain its social commitments.
• Represents a strong technical endorsement for the AntaKori project.

John Black, Chief Executive Officer of Regulus, commented as follows:

"The continued support of Osisko is a strong endorsement of the AntaKori project. Given that equity markets are currently very challenging, we believe this transaction adds value to shareholders by avoiding equity dilution while providing Regulus with cash to continue to advance work programs at AntaKori."

"The next major milestone for the project will be a decision on the Colquirrumi earn-in claims whereby Regulus can earn up a to 70% interest from Buenaventura by completing 7,500 m of drilling. Upon completing the 7,500 m, Buenaventura can elect to either give Regulus a 70% interest in the claims or pay Regulus US$9 million and give Regulus a 30% interest in the claims, with Buenaventura retaining a 70% interest. We plan to complete the 7,500 m of drilling in October and expect a decision from Buenaventura in Q1 2023. With either a 70% or 30% interest, we retain the ability to layback onto these claims which will enable us to increase the size of the pit and thereby increase our resource base at AntaKori. With two drill rigs active on the project, we will continue drilling to expand the mineralized footprint of the project, with the target of completing a resource update around mid-2023."

Details of the Transaction

Regulus, through its wholly owned Peruvian subsidiary, will grant to Osisko an NSR on certain claims of AntaKori ranging from 0.125% to 1.5%. As well, Regulus will transfer a right to buyback a 1% NSR for US$4.5 M on the Maria Eugenia, Maria Eugenia No1 and Rita Margot claims. As per the Strategic Partnership, Osisko previously held the right to acquire 50% of the 1% NSR on Maria Eugenia, Maria Eugenia No2 and Rita Margot if Regulus had exercised its buy-back right. In accordance with the Investment Agreement entered into by Osisko and Regulus, consideration of US$5 million was paid to Regulus on closing. See Table 1 and Figure 1 for details of where the new royalties will be applicable and the overall royalty profile of the project.
