Regulus Resources recently announce the results from two 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 24th and April 5th, 2017).
Holes reported in this news release are AK-17-002, drilled by Regulus and DHSF17-160, 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.
John Black, Chief Executive Officer of Regulus, commented as follows: “We are excited to begin reporting results from longer drill holes that test both the upper volcanic hosted high sulphidation mineralization as well as the underlying skarn mineralization in the Cretaceous sedimentary host rocks. The results from drill hole DHSF17-160 are particularly encouraging with strong mineralization in a hole that is located 220 m from previously reported drill hole AK-17-001 in an area with limited previous drilling on Regulus concessions. These are the first skarn intercepts reported by Regulus from this drilling campaign and they bode well for the overall skarn target size as they significantly extend mineralization to the south. Two additional drill rigs with greater depth capacity will be arriving to the project prior to the end of the month and we look forward to increasing the rate at which we report drill results.”
