Regulus Announces Completion of Mineral Resource Estimate for Integrated Coimolache Sulphide/AntaKori Copper-Gold Project
NEWS RELEASE
Regulus Announces Completion of Mineral Resource Estimate for Integrated
Coimolache Sulphide/AntaKori Copper-Gold Project
June 30, 2026 (Vancouver, BC) - Regulus Resources Inc. ("Regulus" or the "Company", TSX-V: REG,
OTCQX: RGLSF) is pleased to announce that the Company, in collaboration with Compañía Minera Coimolache
S.A. (“Coimolache”, collectively with Regulus the “Parties”) have completed the first phase of the collaboration
agreement previously announced on July 25, 2024. The agreement was designed to evaluate the viability of an
integrated Coimolache Sulphides /AntaKori copper-gold project (“Integrated Sulphide Project”), starting with
the completion of a mineral resource estimate (“MRE”), with the option, upon mutual agreement of the Parties
following the completion of a MRE, to complete a preliminary economic assessment (“PEA”). The results of the
MRE and PEA (should the Parties agree to move forward) can only be publicly released upon mutual agreement
of the Parties and regulatory approvals.
John Black, Chief Executive Officer of Regulus, commented: “The completion of the Integrated Resource
Estimate constitutes a milestone for both Regulus and our neighbours . This is the first fully unconstrained
resource estimate created by a third-party, removing property boundaries and focusing solely on mineralization.
While we don’t anticipate the report being made public, the completion of the study still represents a significant
step forward for the region, as it allows all parties to understand the value that can be unlocked in the district via
collaboration. While we decide next steps regarding our agreement with Coimolache, we continue to de-risk the
project on the ground via advancing our community programs to set the stage for future development.”
The MRE was completed by SRK Peru, which has developed an internal report that has been distributed to the
Parties. The Company will provide no further updates regarding discussions with Coimolache until decisions are
made regarding the MRE and PEA. The Company cannot provide a timeline for a decision at this time.
The AntaKori Project
The AntaKori project, located in Cajamarca, Peru, currently hosts a resource with indicated mineral resources of
250 million tonnes with a grade of 0.48 % Cu, 0.29 g/t Au, 7.5 g/t Ag, and inferred mineral resources of 267
million tonnes with a grade of 0.41 % Cu, 0.26 g/t Au, 7.8 g/t Ag. The AntaKori project is immediately adjacent
to and interfingered with mineral concessions owned by Coimolache. The last mineral resource estimate on the
AntaKori project was completed under a now-expired agreement with Coimolache whereby Regulus could use a
portion (but not all) of the Coimolache drill database to develop a partially integrated resource estimate, but only
report resources from the AntaKori claims. A total of 71,762.04 m of drilling (historical + Regulus) has been
completed on the AntaKori project from 1997-2022. Since the 2019 AntaKori resource estimate was completed,
Regulus has completed 31,666.99 m of drilling on the AntaKori project.
Qualified Person
The scientific and technical data contained in this news release pertaining to the 2019 AntaKori mineral resource
estimate has been reviewed and approved by Dr. Kevin B. Heather, Chief Geological Officer, FAusIMM, who
serves as the qualified person (QP) under the definition of National Instrument 43-101.
