CORE ASSETS CORP. Core Assets Corp. announced the completion of two diamond drill holes totaling 671 metres at the Laverdiere Skarn-Porphyry Project, eastern Blue Property; Atlin Mining District of NW British Columbia. 1,500 metres of exploratory HQ-sized diamond drilling is planned for the Laverdiere Project in June.
2022 drilling efforts are designed to confirm and extend high-grade Fe-Cu-Au skarn and associated Cu-Mo porphyry style mineralization exposed for 800 metres along the western flank of Hoboe Creek, and up to 400 metres depth, situated between the historic North and South Adits. The Laverdiere Project is located proximal to the Llewellyn Fault Zone, coincident with Hoboe Creek in the eastern Blue Property. Laverdiere is characterized as a fine-to-coarse grained and locally massive Fe-Cu-Au-rich skarn (magnetite and/or magnetite-chalcopyrite-dominant±bornite-tetrahedrite-molybdenite-pyrite-pyrrhotite) hosted in dolomitic limestone and marble of the Devonian Boundary Ranges Metamorphic Suite.
Along the western side of Hoboe Creek, dolomitic limestone is overlain by thin-bedded calcareous siltstone, quartzite, and schist all of which are locally folded, dip moderately to the west, and are intruded by an Early Cretaceous post-accretionary granodiorite intrusion of batholith size (Coast Plutonic Complex). The granodiorite is locally foliated, Cu-Mo-bearing, and exhibits potassic alteration in the form of secondary K-feldspar and shreddy biotite after hornblende along the Fe-Cu-Au skarn contact. The highest-grade skarn occurrences observed at Laverdiere are hosted in dolomitic limestone, near the siltstone contact and along the margins of the granodiorite intrusion.
Disseminated and quartz-vein/fracture-hosted chalcopyrite, molybdenite, magnetite, and malachite have been observed in granodiorite outcropping along the Lewellyn Fault Zone (LFZ/Hoboe Creek) for up to 3.9km south from the main Fe-Cu-Au Skarn body.
