GREENWOOD, B.C. — Grizzly Discoveries has identified at least five geophysical anomalies around the historic Mother Lode, Greyhound and Sunset mining areas near Greenwood, and the company is seeking permits to test several of them with drilling this fall.
The Edmonton-based mineral exploration company released preliminary results Sept. 2 from an induced polarization survey completed in April and May at its Motherlode Critical Minerals Target.
The survey covered 12.9 line kilometres along eight north-south survey lines spaced about 200 metres apart. Grizzly reported at least five separate chargeability anomalies, with four producing readings between 30 and 52 millivolts per volt in their central areas.
Grizzly said two of the anomalies are currently about one kilometre by 500 metres and remain open for further expansion.
Induced polarization, commonly called IP, is a geophysical method used in mineral exploration to measure differences in the electrical properties of rock below the surface. Higher chargeability can be associated with disseminated metallic sulphides, which can occur with copper and other mineralization.
The results are exploration targets rather than confirmation of a mineral deposit. IP responses can also be produced by materials including graphite and magnetite, meaning the survey alone cannot establish what is causing the anomalies. Drilling is needed to determine their source.
Grizzly said most of the newly identified anomalies are also associated with elevated copper and gold values found through earlier soil and rock sampling. The company interprets the survey results as possible disseminated sulphides associated with skarn or porphyry-style mineralization.
B.C. MINFILE records show the Mother Lode property, northwest of Greenwood, was developed first through underground workings and later as an open-pit mine. Historical production recovered approximately 77 million pounds of copper, 173,319 ounces of gold and 688,203 ounces of silver.
The nearby Greyhound property also underwent underground exploration early in the 20th century before open-pit mining began in 1969 and continued through 1971. Provincial records say about 900,000 tonnes of ore and waste were excavated during that period.
Grizzly has previously explored the Motherlode area through geological mapping, soil and rock sampling, geophysical work and drilling. Its 2026 program has returned to the historic mining area with additional geophysics intended to refine targets for another round of drilling.
The company said it is working to permit additional drill pads at Motherlode and plans further IP surveying, geological mapping and surface sampling before drilling begins.
Grizzly says additional drilling across its Greenwood-area properties is planned between October and December, including work at Motherlode and potentially at its Sappho and Midway target areas.
Results from other parts of the company’s 2026 Greenwood exploration program are also pending.
A historic mine opening near Rossland’s Kootenay Columbia Trail will be permanently sealed, with a three-week trail closure beginning Sept. 28 so crews can complete the work.
