Mink Ventures Corporation (TSXV: MINK) said on July 14, 2026 that it had finished the second phase of diamond drilling at its Warren nickel, copper and cobalt property about 35 kilometres west of Timmins, Ontario, with 477 metres drilled to test two airborne electromagnetic anomalies. The Toronto company reported no assay values and no visual estimates in that release, saying core logging was complete, sampling was under way and results were expected towards the end of August. Six weeks later the assays arrived, and they reported no significant nickel, copper or cobalt values.

The programme as announced

The two holes were designed to test VTEM Maxwell Plate anomalies, conductive bodies modelled from airborne survey data and located in three dimensions before a drill is moved. Warren sits inside the Kamiskotia Gabbro Complex, which Mink describes as broadly equivalent to the Montcalm Gabbro Complex to the north but separated by a granitic arch. That comparison is the whole exploration argument: the Montcalm complex hosts the former Montcalm Mine, which produced approximately 3.93 million tonnes grading 1.25% Ni, 0.67% Cu and 0.05% Co according to Ontario Geological Survey work cited by the company.

Mink also set out the rest of its season in the July release. A drill was to move to the Montcalm property in late August or early September, ground conditions permitting, and preparation of a winter access road into the northern part of Warren would begin in mid-December ahead of a third phase targeting three new anomalies near a historical hole, ML-1, that returned 0.84% Cu over 4.3 metres. Kevin Filo, a professional geoscientist, officer and director, was named as the qualified person under National Instrument 43-101.

What the assays showed

On August 26, 2026 Mink reported the results. Drilling intersected sulphide mineralisation at the modelled depths for both targets, designated 2050A and 2050B, but no significant nickel, copper or cobalt values were detected. Hole W26-20, which tested 2050A, returned anomalous copper across a 42.00 metre interval from 121 to 163 metres, including 0.50 metres assaying 0.20% Cu. Hole W26-21 returned no significant values. The drill hole table shows a third collar, W26-19, abandoned at 54 metres, so the 477 metres quoted in July covers three collars of which two were completed.

Filo said the programme confirmed the targeting method works, in that “the sulphide zones were intersected at the interpreted target depth”. Mink then redirected its drills. Two holes of approximately 425 metres are planned at the Rankin property, optioned in July, to test two anomalies with what the company calls inordinately high conductive values supported by a coincident gravity response. The Warren phase three programme, three holes over 550 metres, is fully permitted and moves to winter. At Montcalm, an independent review of historical survey data recommended one priority anomaly and downgraded a borehole induced polarisation target the company had intended to drill this autumn.

Analysis: the geophysics passed, the geochemistry did not

These two releases illustrate a distinction that headline exploration results often leave implicit. A conductive anomaly is a physical property of rock; sulphide minerals conduct electricity whether or not they contain payable metal. Mink’s Maxwell Plate work predicted where sulphide would sit and the drill found sulphide there. That validates the survey and the modelling, and it is a real result for a company that has to choose where to spend a small budget. It says nothing about grade, and the assays confirmed as much: 0.20% Cu over half a metre inside a 42 metre anomalous zone, against a historical mine next door that averaged 1.25% Ni over 3.93 million tonnes.

The comparison with the company’s own earlier work is the useful benchmark. Mink’s first phase of Warren drilling returned a semi-massive sulphide intercept of 0.48% Ni, 0.12% Cu and 0.07% Co. Historical bulk samples from the B Zone in the 1950s reported 0.96% Ni and 2.83% Cu in separate samples. Nothing in the 2026 phase two work approaches either figure. That is not a failure of the method so much as a statement about which targets remain untested, and the company’s decision to move the drill to Rankin before returning to Warren in winter reads consistently with that.

A second thing worth tracking is the shifting size of the portfolio as described. The July release put Montcalm at approximately 104 square kilometres and Warren at 11 square kilometres, while the Warren project page describes 1,130 hectares and the Montcalm page approximately 100 square kilometres. By August the company was describing a 115 square kilometre critical minerals portfolio in the Timmins nickel district. These are not contradictions so much as different snapshots after option agreements and staking, but a reader comparing releases months apart should check which basis a given number is on.

The capital structure sets the pace. Mink reported 41,447,296 common shares outstanding on July 14 and 41,672,296 as of August 13, 2026, against 22,485,226 warrants, 3,069,045 options and 1,525,000 shares reserved for issuance, for a fully diluted count of 68,751,567. The warrant book is more than half the current share count. For an explorer with no resource estimate on either property, warrant exercises are the cheapest available funding and also the clearest measure of the dilution ahead. The Warren patents option itself is share-settled in part: Mink issued 250,000 shares and 250,000 three-year warrants exercisable at $0.25 on closing, and must incur $300,000 in exploration spending and issue a further 750,000 shares to exercise.

The metals backdrop

The commodities Mink is looking for have been getting cheaper. The US Geological Survey put the average annual London Metal Exchange nickel cash price for 2024 at about $17,000 per metric ton, or $7.70 per pound, a decrease of 21% from 2023 and the continuation of a downward trend the agency attributes largely to Indonesian surplus. Cobalt was weaker still: the LME cash average fell to about $12 per pound in 2024 from $28.83 in 2022.

Canada remains a significant producer within that market. The USGS lists Canadian nickel mine production of 190,000 tons in 2024, up from 159,000 tons in 2023, with reserves of 2,200,000 tons, and reports that Canada supplied 46% of US primary nickel imports between 2020 and 2023. Canadian cobalt production is listed at 4,500 tons for 2024 against reserves of 220,000 tons. Supply-security arguments for Ontario nickel exploration rest on those trade figures, not on the price series, and the two point in different directions.

What to watch

The Rankin drill results are the next data point, followed by the winter phase three programme at Warren aimed at the volcanogenic massive sulphide setting around hole ML-1 rather than the magmatic sulphide targets tested in phase two. Those are different deposit types with different grade expectations, so the phase two outcome does not predict the phase three one. What has not changed is that Mink holds no resource estimate on any of its properties, and that every programme it plans is funded from a treasury whose main forward component is a warrant book.
