Regulus Resources Inc. (“Regulus” or the “Company”) (TSXV:REG) is pleased to announce the results from three additional drill holes at the Company’s AntaKori copper-gold-silver project in northern Peru. The drilling campaign is underway in collaboration with Compañía Minera Coimolache S.A. (“Coimolache” or “CMC”), the operator of the Tantahuatay gold mine, immediately to the south of the AntaKori project (please refer to Regulus news releases of January 24, 2017 and April 5, 2017). Holes reported in this news release are AK-17-003A, drilled by Regulus and DHSF17-161 and DHSF17-164, drilled by Coimolache. The two companies are drilling simultaneously hence two numbering sequences for drill holes exist. Results are only reported herein for the portions of the drill holes that occur within Regulus concessions.

The AntaKori system hosts two principal styles of copper-gold-silver sulphide mineralization: 1) skarn and breccias within Cretaceous calcareous sedimentary rocks, likely associated with as-yet undiscovered porphyry mineralization; and 2) younger, epithermal high-sulphidation mineralization in overlying Miocene volcanic rocks and breccias that host the adjacent Tantahuatay heap-leach gold mine to the south. The younger high-sulphidation mineralization locally overprints the earlier skarn mineralization, particularly along the southern part of the AntaKori system. Drilling has commenced on the southernmost margin of the Regulus concessions and will proceed to the north over the next few months as permitting allows (see Figure 1). The initial holes will encounter the overlying Miocene volcanic rocks and high-sulphidation style mineralization prior to entering into the Cretaceous sedimentary sequence and skarn at depth. As the drilling progresses to the north, the volcanic rocks terminate and drill holes will commence directly in the skarn/porphyry environment within the Cretaceous sedimentary sequence.

AK-17-003A (938.1m) and DHSF17-161 (689m) were completed to targeted depths and cut both styles of mineralization, with well-developed skarn in the underlying Cretaceous calcareous sedimentary sequence. DHSF17-164 (303.8m) is a shallow hole that only crossed Regulus concessions for the interval from 78.9-109.7m depth within Miocene volcanic rocks. The more significant results from these three holes are listed below with additional details provided in Tables 1 and 2.
