Regulus Resources Inc. Reports 171.95 M of 0.67 % Cueq (1.30% Cueqz Including Zn) from New Area
Regulus Resources Inc. report the results from drill holes AK-22-048, AK-22-049, AK-22-050 and AK-22-051 from the AntaKori copper-gold project in Peru. The goal of holes AK-22-048 and AK-22-049 was to fill-in a gap in the drilling for an eventual resource update and obtain additional information on the higher-grade breccia mineralization encountered in nearby drill holes. Hole AK-22-050 was designed to drill above hole AK-22-047 and provide additional information for an eventual resource update. Hole AK-22-051 was designed to test a previously untested area to the west of the known mineralization. Hole AK-22-051 was drilled to a depth of 1,001.50 m and intercepted several runs of attractive grade mineralization and extended the mineralized footprint significantly to the west, opening a new area for additional drilling. Hole AK-22-050 was drilled to a depth of 530.30 m and intercepted a significant run of attractive grade mineralization confirming the continuity of mineralization previously reported in hole AK-22-047. Hole AK-22-048 was drilled to a 1,273.55 m depth, while hole AK-22-049 crossed the boundary of the Company’s claims at approximately 1,360 m depth and was stopped shortly thereafter. Both holes hit runs of moderate grade mineralization, however the most encouraging information from these holes is that they both intercepted numerous well mineralized porphyry dykes, indicating the presence of a nearby porphyry system. AK-22-048: Drill hole AK-22-048 was drilled at an azimuth of 119 degrees and an inclination of -75 degrees and was collared on the same drill pad as AK-21-046. The hole starts with 9.45 m of overburden material, followed by a 22 m interval of Miocene sub-volcanic intrusion prior to entering the calcareous cretaceous sedimentary sequence. The first intervals of calcareous rocks (Pariatambo Formation) are encountered at 33.55 m as intercalations of banded hornfels and massive retrograde-skarn altered intervals that are affected by moderate oxidation, with the presence of jarosite-hematite and Fe-carbonates, and relics of earlier pyrite-chalcopyrite disseminated mineralization. Narrow younger breccias and galena-sphalerite-carbonate veins also crosscut the oxidized skarn in this interval. The same sub-volcanic intrusion reported above occurs from 65.80 m to 90.20 m, with similar characteristics but this time showing disseminated pyrite-chalcopyrite that locally constitutes mineralized intervals. At 93.95 m the hole entered the more calcareous Chulec Formation, with more abundant and better developed skarn intervals with variable amounts of garnet, chlorite and epidote. Mineralization in this interval consists mainly of pyrite-chalcopyrite-specular hematite dissemination and veins, overprinted by galena-sphalerite-carbonate veins that are more abundant than previous intervals. At 123.10 m, a 100 m interval feldspar-hornblende-biotite porphyry dyke intrudes Chulec Formation and is affected mainly by quartz-sericite-pyrite alteration and prograde/retrograde skarn alteration minerals with complex alteration overprint. Mineralization in this interval is mainly pyritic, with traces of chalcopyrite in the form of disseminations and veins, together with occasional molybdenite and galena-sphalerite veins. From 220.00 m to 303.60 m, intercalations of Chulec Formation banded marble and minor skarn horizons occur with weak pyrite-chalcopyrite disseminations and veins. Several sphalerite-galena veins and semi-massive magnetite-pyrite-chalcopyrite horizons locally constitute mineralized intervals. From 311.80 m to 453.80 m, the hole encountered well-developed skarn intervals of Chulec Formation, intercalated with massive magnetite-pyrite-chalcopyrite horizons. Skarn intervals often shows both prograde garnets and retrograde chlorite-epidote alteration, the latter associated with moderate pyrite-chalcopyrite-magnetite disseminations and veins that become stronger at depth in the reported interval, prior to entering in Inca Formation fine-grained sediments. The contact with Inca Formation is found at 453.80 m and consists of intercalations of hornfels and retrograde chlorite-rich skarn horizons. Mineralization in this interval occurs as both dissemination and veins of magnetite-pyrite-chalcopyrite, as well as some latter galena +sphalerite ±tennantite ±chalcopyrite intermediate sulfidation veins. Farrat Formation quartzites and arkoses are found from 529.50 m to 825.20 m, with a few feldspar-hornblende-biotite porphyry intrusions and crackle breccia intervals. Porphyry dykes are commonly moderately mineralized, with dissemination of pyrite-chalcopyrite associated with sericite-chlorite alteration, with latter enargite-tennantite overprint. From 825.20 m to 925.70 m, breccia intervals are more abundant and are affected by quartz-sericite-pyrite alteration with minor pyrite-chalcopyrite-tennantite-enargite veins and disseminations. At 830.00 m and 845.00 m, two mineralized breccia intervals are found with porphyry matrix. Also, two 1-2 m wide feldspar-hornblende-quartz porphyry dykes occur around 905.00 m, with associated disseminated pyrite-chalcopyrite-bornite. From 925.70 m, the drill hole passes through Farrat Formation quartzites and arkoses, with some feldspar-hornblende-biotite porphyry intrusions and crackle breccia intervals, until the end of the hole at 1,273.55 m depth. Quartzites and arkoses commonly display crackle breccia and vuggy textures, and despite typically being poor host rocks, there are weak to moderate mineralized intervals developed consisting of pyrite-chalcopyrite-bornite-tennantite disseminations and veins. The porphyry dykes are affected by either quartz-sericite-pyrite or sericite-chlorite alteration, with pyrite-chalcopyrite-bornite-tennantite disseminations and veins. AK-22-049: Drill hole AK-22-049 was drilled at an azimuth of 170 degrees and an inclination of -73 degrees and was collared on the same drill hole pad as AK-21-046 & AK-22-048. Drill hole AK-22-049 starts with 9.70 m of overburden material, followed by a 22 m interval of Miocene sub-volcanic intrusion prior to entering the cretaceous calcareous sedimentary sequence. The first intervals of calcareous rocks (Pariatambo Formation) are encountered at 32.50 m as intercalations of hornfels and massive retrograde-skarn altered intervals that are affected by moderate oxidation, with presence of jarosite-hematite and Fe-carbonates, and relics of earlier pyrite-chalcopyrite disseminations. Narrow younger breccias and galena-sphalerite-carbonate veins also crosscut the oxidized skarn in this interval. The same sub-volcanic intrusion reported above occurs from 69.20 m to 97.40 m, with the same alteration assemblage and pyrite dissemination.
