Cascadia Minerals (TSXV:CAM) has picked up the highest grade gold and silver samples so far from its Catch Property in Yukon.
The junior explorer, which has a market capitalisation of C$15.2 million ($16.8 million), reports gold grades of up to 1,065 grams per tonne (g/t) gold and 267g/t silver from outcrop at the Amp Zone.
A second 1.4kg sample from a different section of the same outcrop returned 47.2g/t gold and 19.3g/t silver.
Cascadia says the mineralisation provides evidence of a “large and fully preserved” epithermal target associated with the nearby porphyry system.
CEO Graham Downs says epithermal gold-silver mineralisation is often associated with porphyry systems, but not always preserved.
“The discovery of such high-grade epithermal gold mineralisation over 1km north of a new drill-confirmed porphyry discovery is a significant development for us,” he says.
“The Amp Zone represents another distinct target on this district-scale property.”
In 2023, prospecting samples at Amp returned 0.21% copper with 4.82g/t gold from outcrop.
Cascadia says the Amp Zone also exhibits significant copper mineralisation in rock samples, with a 2023 subcrop sample 60m northwest of the high-grade gold-silver outcrop returning 1.68% copper with 0.72g/t gold and another 2023 sample returning 2.13% copper in outcrop.
The company believes the samples collected so far are suggestive of the potential for both copper-gold porphyry at depth and epithermal gold-silver mineralisation at surface at the Amp Zone.
The latest sampling results were part of a phase-one exploration program at the Catch Property that comprised prospecting, mapping and diamond drilling.
Three diamond drill holes totaling 1,613m were drilled at the Spark Zone and 89 rock samples were collected.
A phase-two exploration program is currently underway, with additional prospecting, mapping, diamond drilling and induced polarisation surveys.
Downs says Cascadia is continuing to follow up on the Amp Zone and other targets while drilling is underway at Spark.
“In addition to our ongoing drill programs at Catch and PIL, soil sampling and prospecting is now underway at the Sands of Time, Macks Copper, and Milner properties, which all have early-stage copper-gold porphyry potential,” he says.
