[{"type":"text","content":"Petrographic Analyses and Geophysics Support Porphyry Copper-Gold Deposit Potential on PJX Resources’ Dewdney Trail PropertyTORONTO, ON / ACCESSWIRE / May 10, 2023 / PJX Resources Inc. (\"PJX\") is pleased to announce that results from Vancouver Petrographics' (\"VanPetro\") thin section and polished section analyses of rock samples from the Estella Basin support porphyry copper-gold deposit type potential on the Dewdney Trail Property. Deposit potential is also supported by large (5 km diameter) ring features in airborne magnetic data that may define the margins of collapsed plutons at depth. Porphyry copper-gold deposits often occur above and along pluton margins.Porphyritic intrusions (alkalic porphyries, felsitic rhyolite, trachy­latite), breccias, meta-sediments, carbonates, plus quartz-filled veins comprise the various Estella Basin samples that were analyzed by VanPetro laboratory. Typical porphyry deposit alteration assemblages (Ca-Mg-Fe-carbonates, pyrite, epidote, sericite, chlorite) as well as disseminated and vein copper minerals were identified and are similar to those that characterize alkalic porphyry copper-gold deposits.The Estella Basin target area, with gold-copper-silver mineralization related to alkalic intrusions, is one of a number of target areas on PJX Resources 116 km² Dewdney Trail Property in the Sullivan Mining District.John Keating, President of PJX commented: \"It has taken 10 years to consolidate the mineral rights to the Dewdney Trail Property and the historical Estella mine. Geological and geophysical data combined with copper and gold mineralization in soils and porphyry intrusions at surface all support the potential to discover porphyry type deposits on the Dewdney Trail Property. There are multiple drill ready targets that we plan to test for the first time this year.\"Factors supporting porphyry deposit potential include:Differentiated intrusions with porphyritic rock types ranging from syenite to granodiorite in composition.Hydrothermal breccias.Copper sulphide and pyrite mineralization in veins and disseminated in the fine-grained groundmass of various porphyry phases (see photo A).Clustering of multiple and varied intrusions.An exposure level that indicates only the top of some intrusions are exposed. This supports the potential for additional mineralization at depth.Air...
