VANCOUVER, British Columbia, April 02, 2019 (GLOBE NEWSWIRE) -- Regulus Resources Inc. ("Regulus" or the "Company", REG TSX.V) 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. Holes reported in this news release are AK-18-028 through AK-18-030 (see Figure 1). Results are only reported herein for the portions of the drill holes that occur within Regulus concessions. All of the holes encountered significant mineralization with the most notable results from hole AK-18-030 which is the first hole to step-out significantly to the northwest of the area of the current resource and encountered an extensive zone of low arsenic copper-gold mineralization in porphyritic intrusive rocks and skarn.

-- This hole is located approximately 500 m to the northwest of any previous drilling reported by Regulus. The hole was altered and mineralized over the entire length. Although grades are not high, the mineralization is persistent throughout the hole and with notably low arsenic contents in the porphyritic intrusive and skarn mineralization in the lower portion of the drill hole (see table 2 below).
John Black, Chief Executive Officer of Regulus, commented as follows: “We are excited to report results for the first major step-out hole to the northwest of the known area of mineralization we have been drilling out at AntaKori. Drill hole AK-18-030 is located approximately 500 m to the northwest of our existing drill pattern in an area where we have geophysical data that suggests the potential presence of additional skarn and/or porphyry style mineralization. The hole encountered extensive alteration and low to moderate grade copper-gold mineralization in both the high sulphidation volcanic hosted environment at the top of the hole and also in extensive porphyritic intrusive rocks and minor skarn in the lower portion of the hole. One of the most encouraging aspects of this mineralization is the low arsenic content with the lengthy intercept reported in intrusive rocks containing an average of only about 50ppm arsenic. The location and orientation of the hole was determined by the presence of an existing permitted pad and was not ideally located to test the most favorable geophysical targets, which makes the results even more interesting as they may represent the peripheral expression of the principal targets. Permitting is underway to allow us to complete additional drilling to the north commencing in Q3-2019.”
Dr. Kevin B. Heather, Chief Geological Officer of Regulus, commented as follows: “Although we have become accustomed to longer and higher-grade intercepts during our Phase 1 drilling, the significance of the hole AK-18-030 results should not be underestimated in terms of both the step out distance of about 500m from previously known mineralization, but also in terms of the amount of mineralized and altered porphyry intrusive and skarn rocks encountered. The rock types, alteration and mineralization encountered all bode well for continued exploration to the north and the testing of the previously identified magnetic high (potential magnetite-bearing skarns) and low (potential porphyry intrusive centers) targets.”
The AntaKori system hosts two principal styles of copper-gold-silver sulphide mineralization: 1) mineralized skarn and breccias (Cu-Au-Ag) within Cretaceous calcareous sedimentary rocks, likely associated with as-yet undiscovered porphyry mineralization; and 2) younger, epithermal high-sulphidation (HS) mineralization (Cu-Au-Ag-As) in overlying Miocene volcanic rocks and breccias that host the adjacent Tantahuatay heap-leach gold mine to the south. The younger high-sulphidation mineralization is characterized by pyrite-enargite and locally overprints the earlier skarn mineralization (pyrite-chalcopyrite-magnetite), particularly along the southern part of the AntaKori system. Drill holes at AntaKori typically encounter the overlying Miocene volcanic rocks and high-sulphidation style mineralization prior to entering 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 (see Figures 2-4).
AK-18-028 and AK-18-029 were collared to test Regulus mineral concessions, within the footprint of the newly reported AntaKori NI 43-101 Indicated and Inferred Mineral Resources (see news release of March 1, 2019), to confirm and extend the known, but only partially delineated resource. AK-18-030 is located more than 500 m to the northwest of any drilling to date and encountered extensive mineralization both as high sulphidation epithermal mineralization in Miocene volcanic rocks at the top of the hole and also as lower grade but extensive copper-gold mineralization in underlying intrusive rocks and skarn.
Discussion of results
Table 1 below provides details regarding the mineralized intercepts encountered in drill holes AK-18-028 to AK-18-030. The locations of the reported drill holes are indicated on Figure 1. The design of the current drilling program is for holes spaced on approximately 150 m centres along drill sections oriented at 045 degrees (SW-NE).
Drill Holes AK-18-028 and AK-18-029 were both located within the area of previous Regulus drilling that forms the basis for the recently reported Mineral Resource Estimate (see news release of March 1, 2019). These holes were completed at the end of 2018, after the cut-off deadline for inclusion in the Phase 1 drilling program used for the resource estimate. They are located to fill gaps in the drilling with potential to add to or improve confidence in the resource estimate. These holes will be included in the Phase 2 drilling program projected to consist of approximately 25,000 m of drilling to be completed in 2019.
AK-18-028 was drilled on section line 650NW at an azimuth of 225 degrees and a plunge of -85 degrees. The hole cut the altered and mineralized Miocene volcanic sequence to a depth of approximately 228 m and then intersected well developed skarn to a depth of approximately 460 m when extensive breccia units were encountered to the end of the drill hole at 975 m.
AK-18-029 was drilled on section line 900NW at an azimuth of 045 degrees and a plunge of -70 degrees. The hole cut the typical sequence of Miocene volcanic rocks to a depth of approximately 350 m and mineralized skarn in Cretaceous carbonate rocks to a depth of approximately 680 m. The final part of the hole cut extensive breccia that is variably mineralized and ended at 1,112m.
Drill hole AK-18-030 was drilled from a pre-existing platform allowed under existing permits. The site is over 500 m to the northwest of the previous drilling on Regulus mineral concessions. The hole was drilled at 045 degrees to the northeast at a plunge of -70 degrees. Geophysical data indicates the potential existence of several intrusive centers (magnetic lows) with annular magnetic highs representing potential zones of skarn development in this area to the north and northwest of the main area drilled by Regulus. Hole AK-18-030 is not ideally located to test the principal targets; it essentially tests the boundary between targets. The hole intersected altered and mineralized Miocene volcanic and intrusive rocks to a depth of 411 m prior to entering into the older basement rocks which were predicted to be Cretaceous sedimentary rocks and favorable hosts for skarn formation. However, the hole encountered extensive porphyritic intrusive rock with blocks and remnants of the Cretaceous sedimentary rocks altered to skarn. The porphyritic intrusive rock is pervasively affected by phyllic alteration and hosts low to moderate grade copper-gold mineralization associated with veinlets of pyrite-chalcopyrite-magnetite. The higher ratio of pyrite/chalcopyrite and phyllic alteration suggest a peripheral porphyry environment. Endoskarn is also developed within the porphyritic intrusive, indicating interaction with the calcareous wall rocks. Mineralization in the intrusive is notably lower in arsenic than the high sulphidation epithermal mineralization in the overlying Miocene volcanic sequence with an average of approximately 50ppm arsenic and significant intervals with arsenic levels averaging 25ppm (see Table 2).

| The grades are uncut. HS = high-sulphidation epithermal style mineralisation. CBM = carbonate-base metal style epithermal mineralization. This table reports the mineralized intervals based upon lithology and demonstrates the notable difference in arsenic content between high-sulphidation mineralization in the Miocene volcanic sequence (typically 1000-5000 ppm As) and the lower concentrations found in the zones of skarn mineralization (typically 100-400 ppm As). | ||||||||
The true widths of the mineralized intervals reported in Tables 1 and 2 are difficult to ascertain and additional drilling and geologic modelling will be required to better constrain the geometry of the mineralized zones. High-sulphidation epithermal mineralization within the Miocene volcanic sequence is characterized by extensive zones of low to moderate-grade disseminated and fracture-controlled mineralization that enclose zones of higher grade mineralization. These higher grade zones consist of irregular pyrite-enargite veins, veinlets, and open space infilling that exhibit both a subvertical structural control and a sub-horizontal permeability or manto control within the volcanic sequence. The margins of the higher grade high-sulphidation epithermal zones are generally not sharp or planar in nature. Skarn style mineralization in the Cretaceous sedimentary sequence is mainly controlled by the sub-horizontal stratigraphy and reported mineralized intercepts are probably close to true thicknesses as the drill holes are steeply inclined at 60-90 degrees. In addition to high-sulphidation epithermal and skarn styles of mineralization, the project also exhibits zones of irregular veins and veinlets of chalcopyrite-pyrite-anhydrite-quartz that are thought to be more typical of porphyry copper style mineralization and likely occurring as broad zones of stockwork veining rather than distinct veins. This latter style of mineralization typically overprints skarn mineralization and increases the overall grade. Mineralization at the AntaKori deposit also occurs within breccias as both mineralized fragments (post-mineral breccias) or as infilling of voids within the breccia (pre-mineral breccias). Mineralization within breccias tends to be irregular but the majority of the breccias bodies are subvertical and planar in nature.
2019 Drilling Program
The three holes reported in this release were completed in late 2018 after the cut-off date for inclusion in the mineral resource estimate presented in March 2019 (see news release of March 1, 2019). They are part of the Phase 2 drilling program to be completed in 2019 and followed by the preparation of an updated mineral resource estimate in early 2020. The Phase 2 drilling program is anticipated to consist of approximately 25,000 metres of additional drilling and has recently recommenced with one rig currently drilling and a second rig ready to start drilling soon (see figure 1 for locations). When the rainy season stops in May the rig count will be incrementally increased to 4 to 5 drill rigs to allow the completion of the planned drilling by the end of 2019. The Phase 2 drill program will initially focus on immediate extensions to the current resource including drill holes in the vicinity of recently reported AK-18-26 and will include drilling to offset the mineralization reported in AK-18-030 in this release. Approval of an additional drilling permit is anticipated by Q3 2019 that will allow drilling further to the north and northwest to test geophysical targets that may represent additional skarn and/or porphyry style mineralization.

Having the extensive and varied experiences of both Dr. Windle and Dr. Redwood on the Antakori team, both experts on large porphyry-skarn-epithermal systems, will greatly enhance the company’s technical and exploration abilities during next stages of the project’s development.
Sampling and Analytical Procedures
Regulus follows systematic and rigorous sampling and analytical protocols which meet and exceed industry standards. These protocols are summarized below and are available on the Regulus website at www.regulusresources.com.
All drill holes are diamond core holes with PQ, HQ or NQ core diameters. Drill core is collected at the drill site where recovery and RQD (Rock Quality Designation) measurements are taken before the core is transported by Company truck to the Regulus core logging facility in Cajamarca, where it is photographed and geologically logged. The core is then cut in half with a diamond saw blade with half the sample retained in the core box for future reference and the other half placed into a pre-labelled plastic bag, sealed with a plastic zip-tie, and identified with a unique sample number. The core is typically sampled over a 1 to 2 metre sample interval unless the geologist determines the presence of an important geological contact. The bagged samples are stored in a secure area pending shipment to a certified laboratory sample preparation facility. Samples are sent by batch to the ALS laboratory in Lima for sample preparation and assay. Regulus inserts certified control standards, coarse field blanks, and duplicates into the sample stream to monitor data quality. These standards are inserted “blindly” to the laboratory in the sample sequence prior to departure from the Regulus core storage facilities. At the laboratory the samples are dried, crushed, and pulverized and then analyzed using a fire assay – AA finish for gold and a full multi-acid digestion with ICP-AES analysis for other elements. Samples with results that exceed maximum detection values for gold are re-analyzed by fire assay with a gravimetric finish and other elements of interest are re-analyzed using precise ore-grade ICP analytical techniques.
