Laverdiere Project
3-D depiction of modelled geology at the Laverdiere Copper Project highlighting the two main Target areas (Valley and Main) and the widespread distribution of significant copper grades at surface and along the Llewellyn Fault. Drillhole intercepts are reported as length weighted values and true width is unknown currently.
In 2024, a 20cm thick east-west striking quartz vein grading 0.44 g/t Au and 0.83% Cu was discovered. Multiple other stringer-oriented northeast-southwest returned anomalous values for Cu and Ag.
The samples that generated interest in the Valley Zone at Laverdiere are summarized in Table 1 below, along with 2024 results. Historic highlights include samples 8801 and 8803, which returned values of 0.11g/t Au and 2.73% Cu, respectively. Samples collected in 2022 returned values up to 3.24% Cu and 3210 ppm Mo. In addition to the reconnaissance field program, the Laverdiere geological model was revisited and remodeled by Core Silver geologists over the Fall of 2024.
At the Laverdiere Copper Project, an extensive Cretaceous granodiorite intrusion hosts widespread Cu-Mo-Ag-Au porphyry mineralization over a 1.8km by 2.2km trend. The intrusion is associated with zones of very high-grade Fe-Cu-Au-Ag massive sulphide skarn that are exposed at surface along the western flank of the prolific Llewellyn Fault Zone (LFZ) at the porphyry-marble contact. In 2024, high-grade porphyry mineralization at the newly defined Valley Zone was structurally mapped and sampled, and updates to the Laverdiere Copper Project 3-D geologic model were completed.
Various datasets from the 1973 Aeromagnetic (Rio Plata, 1973) and the 2021 VTEM (Geotech, 2021) Surveys showing overlapping, circular magnetic low geophysical responses, interpreted as a zone of increased hydrothermal alteration coinciding with a high-grade porphyry centre at the Laverdiere Copper Project. The 2021 Calculated Vertical Gradient (CVG) data show multiple, grouped donut-shaped magnetic lows at the Valley Zone that may represent clustered porphyry centres.
Drilled and mapped high-grade copper-bearing skarn mineralization at Laverdiere is coincident with embayments in the contact zones of the expansive Cretaceous intrusions on the west side of Hoboe Creek. A large unexplored embayment in the intrusion is mapped 8km to the south of the to-date explored zone at Laverdiere and is in contact with Boundary Range metamorphic rocks at this location. Apophyses of the larger granodiorite intrusion are also mapped in contact with limestone and marbles amenable to massive sulphide skarn mineralization approximately 7km to the southwest of the known zones of high-grade porphyry-skarn mineralization.
