Drilling at Casper, 20km north of E&L in the Eskay Camp of
Five diamond drill holes followed-up the first four holes into the Casper Discovery reported on
Drill core samples from silicified volcanic rocks containing quartz-carbonate-sulfide veins at a depth of 129.5 m returned 10.15 g/t gold over 4.5 m (CAS-21-05: 129.5-134m), including 29.94 g/t gold over 1.5 m (CAS-21-05: 129.5-131m). This intercept may be continuous with the 4-meter-thick mineralized silicified unit containing visible gold intercepted in 2020, located approximately 65 m to the northwest. This hole validates the exploration concept that gold mineralization is associated with a broad silicified volcanic unit rather than discrete local veins, expanding the potential for a much larger gold-bearing mineral system.
Elevated gold abundances along a 260m strike length are confirmed by drilling, and the system remains open with increasing potential to the southeast. Previously reported surface trenching has also exposed the Casper vein for over 120m strike length, and select rock samples exceeding 1.0 g/t Au occur at surface for over 330m, within a 500 m wide zone of anomalous gold concentrations in soil.
Fine grained visible gold has been intercepted in both 2021 and 2022 drilling as well as 2022 trenching. Multiple grab samples with visible gold trenched in 2020 from the east side of the main Casper vein returned 249.0, 92.3, 75.3 and 58.4 g/t gold
Exploration at Casper has identified a continuous zone of gold-rich quartz vein mineralization in association with soil geochemical gold anomalies and extensive rock-chip gold anomalies both along strike and across strike indicating potential for multiple sub-parallel veins of mineralization. The development of silicified country rocks with elevated gold content, and the complex structural relationships evident from the LiDAR data highlight the potential that the results sit on the edge of a much larger gold-bearing mineral system where altered country rocks and quartz veins with elevated gold are controlled by NW-SE and N-S lineaments corresponding to a shear zone. An exciting opportunity exists to expand the footprint of the mineral zone and identify structurally-controlled blow-outs with economically interesting grade and thickness of gold-silver mineralization.
