Step-Out Drilling Intersects 22m of 4.24% Copper and 2.16 g/t Gold in Yukon

The Whitehorse Copper Belt in the Yukon produced 267.5M pounds of copper, 225,000 oz of gold, and 2.8M oz of silver from 10.5M tonnes of ore between 1967 and 1982 (Source). A new high-grade discovery in that belt, backed by a fully funded drill program, is the kind of story that tends to build momentum quickly. Today, a Canadian junior advancing an aggressive copper-gold portfolio in the Yukon logged single-session gains after validating a priority target trend.

Gladiator Metals Corp. (TSX-Venture: GLAD)(OTCQB: GDTRF) reported the latest high-grade assay results from the Cub East prospect, a recent discovery positioned within the broader Bear Cub trend at its Whitehorse Copper Project. Three step-out diamond drill holes, completed 40m north of the previously released sections, successfully confirmed high-grade strike continuity over a greater than 80m interval.

The batch was headlined by hole BCG-023, which intersected a broad mineralized zone of 35.9m grading 2.68% Cu, 1.35 g/t Au, and 19.55 g/t Ag from 172.1m downhole. This intercept includes a high-grade core of 21.9m grading 4.24% Cu, 2.16 g/t Au, and 31.04 g/t Ag.

The remaining two step-out holes demonstrated consistent, repeatable thickness and grade profile characteristics:

• BCG-022: Intersected 23.43m grading 1.36% Cu and 0.59 g/t Au from 159.95m, plus a deeper secondary zone of 30m grading 1.32% Cu and 0.50 g/t Au from 223m (including 15.17m of 2.32% Cu and 0.86 g/t Au).
• BCG-021: Returned 22m grading 1.24% Cu and 0.44 g/t Au from 186m downhole, including an internal high-grade zone of 10m of 2.24% Cu and 0.78 g/t Au.

All three step-out holes successfully encountered texturally robust copper-gold-silver magnetite skarn mineralization. The system remains completely open in all directions.

To complement the drill data, Gladiator finalized a 3D Induced Polarization (IP) geophysical survey across a 1.5km - 1.5km grid at Cub East. Early structural interpretations from the survey have outlined a newly defined, non-linear strike anomaly extending over 900m. This large-scale geophysical footprint suggests system expansion potential beyond the current 80m of drill-confirmed high-grade strike, allowing the company to direct rigs to test down-dip and along-strike targets.

Gladiator is currently fully funded for a 45,000m exploration. At least 8,000m of grid-spaced infill and step-out drilling are mapped out at Cowley to support a planned maiden Mineral Resource Estimate.

GLAD / GDTRF shares responded favorably to the discovery metrics, climbing 18.3% and 19.5% to C$2.65 and US$1.89, respectfully. With sample batches from the final step-out holes at Cub East actively moving through the assay pipeline and initial resource delineation numbers from Cowley expected over the coming weeks, the company maintains a active catalyst flow.
