Drilling yielded three meters at 604 grams per tonne silver at 0.68% tin from 24 meters, the filing said.

It showed that the deposit remains open in all directions, the filing added.

Sky Metals is on track to deliver an updated mineral resource estimate at the project in the first half of the year, the company said.
