KINTAVAR COMMENCES DOWNHOLE GEOPHYSICAL SURVEY TO TEST NEW VMS INTERPRETATION AT ROGER COPPER-GOLD PROJECT, CHIBOUGAMAU, QUEBEC

Kintavar Exploration Inc. has commenced downhole geophysical survey work of historical holes on its Roger property, five kilometres north-northwest of Chibougamau, Que. The objective of the survey is to detect the centre of gravity of a massive sulphide deposit interpreted to exist on the property.

Highlights:

• New geological model identifies volcanic-hosted massive sulphide (VMS) potential at Roger for the first time;
• Downhole electromagnetic and induced polarization (IP) surveys are now under way to locate the core of a potential Cu-Zn-Au-Ag (copper-zinc-gold-silver) sulphide body;
• Off-hole anomalies will be prioritized for drill testing;
• Early relogging and geochemical work confirm LaRonde-style geological similarities and strong base metal grades in historical drilling.

"Our preliminary evaluation has identified a potential Cu-Zn-Ag-Au massive sulphide marker horizon that has been traced along a strike length of at least 1.4 km," said Peter Cashin, Kintavar's chief executive officer. "The strong geological similarities of Roger with Agnico-Eagle's LaRonde mine rocks gives us confidence that a base metal sulphide deposit could exist on the property. Positive geophysical results will be confirmation of the integrity of our geological model."

Interpreting the Roger copper-gold project

While the Roger deposit was historically interpreted as a porphyry-style system, Kintavar's recent work suggests otherwise. The high degree of deformation and alteration observed in the rocks raises questions about the intrusive origin of the mineralization. Instead, evidence now points to a volcanic-hosted massive sulphide (VMS) environment.

Significant historical intersections support this reinterpretation, including 7.0 per cent Zn, 0.36 per cent Cu, 10.5 g/t Ag over 6.0 m and 3.6 per cent Zn, 3.2 per cent Cu, 123.5 g/t Ag, 27.0 g/t Au over 1.2 m. These intervals occur within iron-chlorite-altered felsic to intermediate tuffs, agglomerates and banded flows, characteristic of VMS-style horizons. This marker horizon has now been traced along at least 1.4 km of strike length.

To refine this model, Kintavar has systematically compiled and re-evaluated all historical data from Roger, completing relogging and resampling of drill core, detailed rock geochemistry, and age dating of mineralized host rocks. In parallel, physical property testing (density, magnetic susceptibility, conductivity, resistivity and chargeability) across all lithologies is under way to better detect subtle geophysical signatures of deep sulphide targets.

Geological comparisons with known VMS deposits in the Abitibi greenstone belt

The geological reinterpretation of the historical exploration work completed on the property shows very strong similarities to the geological environment of the Agnico-Eagle's LaRonde 20N massive sulphide deposit. Results from major oxide and trace element geochemical analysis from sampling of historical core completed in early August are comparable with the chemical signatures of LaRonde mine rocks.

Downhole geophysical survey work

The best means of detecting the deep presence of massive sulphide bodies is with the use of in-hole geophysical surveys. Survey crews from Abitibi Geophysics of Val d'Or, Que., were mobilized to the property on Oct. 1 and commenced survey work on Oct. 2. Data collection of the 12 to 15 drill holes to be surveyed, covering 1.4 kilometres strike length of the Roger target, is estimated to be completed within two weeks.

Two methods of detection of sulphide conductors, borehole electromagnetic (BHEM) and borehole induced polarization (BHIP) systems will be used for this work:

1. For the company's BHEM, Abitibi will utilize the DigiAltantis BHEM probe and TerraScope 400V transmitters to acquire three-component B-field data with high-dipole moment using a low base frequency for high conductance targets and a single loop (400 to 600 metres side) configuration. The radius of detection by this method from the hole axis is about 150 m and is used to detect the presence of massive sulphide conductors.
2. For the BHIP, the company will use its H2H-3D-IP configuration in 12 to 15 pairs of holes. The current electrodes C1 and C2 are positioned at surface far from (twice the maximum depth of the surveyed holes) and on both sides of the zone of interest. Subsequently, two potential electrodes, P1 and P2 (receivers), are introduced in two predetermined holes at the same depth and are simultaneously lowered into the pair of holes as readings are performed. This method is used to detect the disseminated sulphide cloud commonly surrounding massive sulphide deposits.

Roger exploration plan for 2026

Geophysical targets identified from the survey work will be drill tested during the winter of 2026.
