Stuhini Exploration Ltd (TSX-V:STU), the Canada-focused metals explorer, has told investors that a high-resolution airborne geophysical survey had been completed at its Big Ledge zinc project in British Columbia, underscoring the potential to expand the resource there.
The helicopter survey spanned 50.93 square kilometres (sq km) and used the company SkyTEM's proprietary time-domain electromagnetic (TDEM) and magnetic survey system.
Stuhini said that preliminary maps have revealed overlapping signatures for around 14 km, interpreted to represent the mineralized horizon and show the potential for expanding the resource.
"We are pleased to see that the geophysics matches the known mineralization and indicates that the mineralized horizon possibly extends well beyond Teck Resources' crown grants, and onto the company's claims surrounding the crown grants," Stuhini's CEO Dave O'Brien said in a statement. "The project's location and its proximity to power and infrastructure makes Big Ledge a very attractive zinc asset."

The Big Ledge covers 5,093 hectares (Ha) and is accessible by a forest service road from Highway 23. Between 1948 and 1966, a total of 10,060 metres (m) of drilling was completed by Cominco, which hit up to 60m of mineralization.
Cominco reported a non-compliant estimated mineral reserve of around 100 million tons of 4% zinc (with minor lead), including about 10 million tons of 7% zinc.
Stuhini's portfolio of exploration properties includes the flagship Ruby Creek property, which sits around 20km east of Atlin, BC; the Que project , which is approximately 70km north of Johnson's Crossing in the Yukon; the South Thompson project around 35km northwest of Grand Rapids, Manitoba; and the Big Ledge property around 57km south of Revelstoke, BC.
