Grizzly Maps Five IP Anomalies at Motherlode in Greenwood, BC

Grizzly Discoveries said preliminary results from a Phase 2 induced polarization survey run in April and May 2026 identified at least five discrete chargeability anomalies at its Motherlode critical minerals target near Greenwood, British Columbia, with four returning core readings of 30 to 52 mV/V.

Grizzly Discoveries Inc. (TSXV: GZD; OTCQB: GZDIF; FSE: G6H) has released preliminary results from a Phase 2 induced polarization survey at its Motherlode critical minerals target near Greenwood, British Columbia, saying the geophysics has outlined at least five discrete chargeability anomalies across ground that already carries high-grade copper and gold surface samples.

The survey was run in April and May 2026 as a follow-up to earlier surface sampling and to historical drilling on the property. Four of the five anomalies produced numerous readings in their cores ranging from 30 up to 52 millivolts per volt (mV/V). Two of the features are on the order of 1 km by 500 m in their current extent and remain open, meaning the survey grid stopped before the anomaly did.

What a chargeability anomaly actually tells you

Induced polarization is a ground geophysical method that measures how well rock holds an electrical charge after a current is switched off. Disseminated sulphide minerals \u2014 the hosts for copper in porphyry and skarn systems \u2014 hold that charge unusually well, so a chargeability high is a proxy for sulphide content at depth. Millivolts per volt is the unit of that response.

What IP does not do is tell you what metal is in the sulphide, or how much. Graphite, pyrite and clay alteration can all light up a chargeability map without a gram of payable copper attached. That is why the coincidence Grizzly is describing matters more than the raw mV/V numbers: the company says most of the anomalies have moderate to strong copper and gold in soils and in rocks sitting over them, which narrows the range of things the geophysics could be responding to.

The surface numbers behind that claim are the strongest part of the release. Each of the three pit areas \u2014 the Greyhound Pit, the Sunset Pit and the Motherlode Pit \u2014 has yielded numerous samples anomalous in copper at greater than 1% and up to 5%, and in gold at greater than 1 gram per tonne. Those are rock-chip and soil grades from historic workings, not drill intercepts or a resource, but they establish that mineralisation reaches surface across the target.

The size of the target, and the size of the company

A 1 km by 500 m chargeability body covers roughly half a square kilometre in plan, on an illustrative basis from the dimensions Grizzly gave, and it is described as open for expansion in both figures accompanying the release. Two features of that scale, plus three smaller ones, is a respectable inventory of drill targets for a single season of geophysics on a brownfield property with old pits already on it.

The market treatment of that news says a good deal about where micro-cap exploration sits in 2026. The OTCQB line, GZDIF, last traded at 0.05, up 13.64% on the day from a prior close of 0.04, with a session range of 0.04 to 0.05, as of 15:23 GMT on September 2, 2026. That is a double-digit percentage move expressed in a single tick of price \u2014 the arithmetic of a sub-nickel stock, where the bid-ask spread and the day's entire range can be the same penny.

For context, the broader market was firm but unexcited on the same session: the S&P 500 tracker was at $765.96, up 0.55%, the Nasdaq 100 proxy at $709.13, up 0.21%, and the Dow tracker at $530.84, up 0.59%. Exploration results move small caps on their own logic, not the index's.

From geophysics to a drill bit

The unavoidable next question is funding. An IP survey is cheap relative to drilling; converting five anomalies into tested targets is not. Nothing in the announcement sets out a drill program, a budget, a rig contract or a timeline, and readers should not assume one exists. The release describes preliminary results, which means the data are still being processed and inverted \u2014 a step that typically refines the depth and geometry of each anomaly before collar positions are chosen.

Investors following the story can watch for a small number of concrete markers. First, final inverted IP sections and any three-dimensional modelling, which will show whether the chargeability bodies are shallow enough to be drilled economically. Second, whether the survey grid is extended to close off the two large open anomalies. Third, any financing \u2014 for a company trading at this level, a drill campaign almost certainly requires new equity, and the terms of that raise will matter as much to existing holders as the geology does. Fourth, the historical drilling Grizzly cites as part of the rationale: re-logging or re-assaying old core is a low-cost way to test whether the IP response lines up with what past operators actually intersected.

Where Greenwood fits

The Greenwood camp in southern British Columbia is old ground, with pits and workings that predate modern geophysics. That cuts both ways. Historic activity is evidence that mineralisation is present and was once considered worth mining, and it leaves behind sampling and drill records that a junior can use rather than pay for. It also means the obvious surface expressions have generally been looked at before. The argument for a company like Grizzly is that IP sees what surface prospecting could not \u2014 sulphide bodies beneath cover and between the old pits.

Copper is the reason that argument is being made now. Grid buildout, electrification and the broader critical-minerals push have kept exploration capital flowing toward copper-gold targets in stable jurisdictions, and British Columbia qualifies on both counts. The details of the survey and the accompanying figures were set out by the company in a release carried by INN Precious Metals.

For now, the honest description of Motherlode is a set of geophysical targets with supportive surface geochemistry over historic workings. That is a real step forward for an explorer of this size, and it is several steps short of a discovery. The drill is the only instrument that settles the difference.

Frequently asked questions

What did Grizzly Discoveries report at Motherlode?

Grizzly Discoveries announced preliminary results from a Phase 2 induced polarization survey carried out in April and May 2026 at its Motherlode critical minerals target near Greenwood, British Columbia. The survey identified at least five discrete chargeability anomalies, four of which returned numerous core readings between 30 and 52 millivolts per volt, near the Greyhound, Sunset and Motherlode pits.

What is an induced polarization survey?

Induced polarization is a ground geophysical technique that measures how long rock holds an electrical charge after a current is switched off. Disseminated sulphide minerals, which commonly host copper, retain that charge strongly, so high chargeability readings measured in millivolts per volt can indicate sulphides at depth. It does not identify which metal is present or at what grade.

How large are the anomalies Grizzly identified?

Grizzly said a couple of the chargeability anomalies are on the order of 1 kilometre by 500 metres in their current mapped size, and that they remain open for further expansion, meaning the survey grid ended before the anomaly did. Three additional discrete anomalies were also identified within the same target area.

What surface grades support the geophysical targets?

According to the company, each of the Greyhound, Sunset and Motherlode pit areas has produced numerous samples anomalous in copper at greater than 1% and up to 5%, and gold at greater than 1 gram per tonne. Most of the chargeability anomalies have moderate to strong copper and gold in overlying soils and rocks.

How did Grizzly's shares trade on the news?

The OTCQB-listed line, GZDIF, last traded at 0.05, up 13.64% from a prior close of 0.04, with a day range of 0.04 to 0.05 as of 15:23 GMT on September 2, 2026. At a sub-nickel share price a single tick produces a double-digit percentage move, so the size of the gain overstates the change in value.

Has Grizzly announced a drill program at Motherlode?

No. The release covers preliminary geophysical results only and does not set out a drill program, budget or timeline. Investors watching the story should look for final inverted IP sections, any extension of the survey grid to close off the two larger open anomalies, and any financing needed to fund drilling on the targets.
