Spring 2022 Diamond Drilling Program At Poplar Copper Deposit
VANCOUVER - Universal Copper Ltd. reported drill results from the remaining Spring 2022 diamond drilling program holes at the Poplar Copper Deposit, located southwest of Houston, British Columbia. All drill targets in the Poplar copper-gold exploration district are shallow and road accessible, within 88 km of rail infrastructure.
Highlights: Hole 22-PC-138 – 0.500% copper equivalent (CuEq)– 0.401% copper, 0.15 g/t gold and 1.27 g/t silver over 214.4 meters; Hole 22-PC-139 – 0.564% copper equivalent (CuEq) – 0.412% copper, 0.02% molybdenum, 0.10 g/t gold and 1.14 g/t silver over 162.8 meters, within a larger interval of 222.8 meters at 0.0461% CuEq – 0.338% copper, 0.017% molybdenum, 0.08 g/t gold and 0.96 g/t silver.
Clive Massey, CEO, said, “Our ongoing ability to recover long intervals of porphyry copper mineralization at Poplar is the result of several months of focused technical work including drill core re-logging and detailed geological modeling. The three-dimensional targeting framework is coming into focus for the first time in the project history and Universal Copper intends to leverage newly defined geological controls on mineralization to continue to produce robust porphyry copper intercepts. Our objective is to increase the grade and tonnage of the Poplar Resource and establish it as a top-tier road accessible deposit in the Central British Columbia Porphyry-Epithermal Belt.”.
The 2022 Poplar drill holes were designed to: a) follow-up on the 0.546% copper over 129 meters discovered in the bottom of 21-PC-135; b) expand the higher-grade portion of the known mineralization to the northwest and c) test the first of the Vector Geological Solutions targets identified from their early 2022 targeted drill core logging initiative. Hole 22-PC-138 was designed to test the southwest edge of the apparent low-grade core of the high-grade ring associated with the Main Zone. The hole intersected 214.4 meters averaging 0.401% copper, before trending into the lower grade material. A 5 meter shear zone with fault gouge at 204 meters roughly corresponds to the marked decrease in grade, suggesting high grade domain is fault bound as has been suggested by the recent geological modeling by Vector Geological Solutions.
Mineralization and alteration in drill hole 22-PC-138is associated with intensely altered porphyry intrusions and consists of pyrite, chalcopyrite, molybdenite and trace bornite. Pyrite and chalcopyrite form disseminations, fracture fillings, stringers, veins, and veinlets in domains of dense quartz vein stockwork and dikes. Molybdenite, where observed is associated with quartz-sulphide veins, and is typically associated with pyrite and chalcopyrite. Potassic alteration (biotite and K-feldspar) of varying intensity and silicification were noted through the strongly mineralized upper section of 22-PC-138, with sericite and silicification dominating below the fault.
Drill hole 22-PC-139 was designed to test one of the target areas identified by the Vector Geological Solutions geological modeling. The hole significantly expanded the mineralization footprint to the northwest, intersecting 162.8 meters of 0.412% copper within a longer 222.8 meter interval of 0.338% copper. Mineralization in drill hole 22-PC-139 is characterized by disseminated pyrite and chalcopyrite, quartz veinlet pyrite, chalcopyrite and local molybdenite. Alteration consists of moderate to intense potassic flooding, silicification in addition to sericite, with the potassic alteration decreasing toward the bottom of the hole.
The entire length of core for 22-PC-138 and 22-PC-139 was sawn and sampled at continuous 3 meter or less intervals, with a few samples taken at shorter or longer intervals based on apparent lithological, alteration or mineralization contacts. Half of the core was bagged, sealed and securely stored until shipment to the laboratory. The other half was retained in a secure storage location. Certified reference standards, a certified reference blank, and sample duplicates were placed in the sample stream of each drill hole alternating at every 10th to 18th interval. The secured and sealed samples were packed into rice bags, sealed and securely stored until they were turned over to the local trucking company for transport to the ALS prep lab in Kamloops, B.C. with the prepared pulps subsequently sent to the ALS Mineral Laboratory ("ALS") in North Vancouver, B.C.
