Re-Interpreting the Roger Copper-Gold Project

While the Roger deposit was historically interpreted as a porphyry-style or intrusion-related Au-Cu system, Kintavar's recent work suggests that strong potential for gold-rich basemetal sulphides also exist on the property. The high degree of deformation and alteration observed in the rocks raises questions about the prior intrusive-only origin of the mineralization.

Base metal sulphide intervals across the property are observed to occur within iron chlorite-altered felsic to intermediate tuffs, agglomerates, and banded flows, characteristic of VMS-style horizons. This mineralized 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 was completed to better detect subtle geophysical signatures of deep sulphide targets.

Geological Comparisons to 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 and geochemical environment of the Agnico Eagle's LaRonde 20N massive sulphide deposit¹. Results from major oxide and trace element geochemical analysis from sampling of historical core completed in early August are comparable to the chemical signatures of LaRonde Mine rocks.

Detailed Results of Kintavar's Borehole Electromagnetic Survey

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, Quebec were mobilized to the property on October 1 and commenced survey work on October 2. Borehole electromagnetic data (BHEM) was collected in nine historical drillholes across 1.4 km strike-length of the Roger mineralized system (see Figure 1 ). The survey work was completed on October 17^th. The results of the final interpretation of the field data were recently received and are herein summarized.

Abitibi utilized the DigiAltantis BHEM probe and TerraScope 400V transmitters to acquire 3-component B-Field data with high dipole moment using a low base frequency for high conductance targets and a Single loop (400 to 600m 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. A total of nine holes for 16 downhole tests (some holes were probed twice using different loop geometries to optimize the resolution of the EM signal) were completed.

NE Sector

BHEM surveys were completed in holes over the northeastern area of the Roger mineralized (see Figure 2 ). The survey was focused on borehole 1206-13-57, where massive sulphides grading 7.0% Zn, 0.36% Cu, 10.5 g/t Ag over 6.0 m were detected within the Roberge ultramafic intrusive south of Roger mineralization.

A series of strong to moderate off-hole conductors were identified below historical drillhole 1206-08-25, 13-57, 18-93, 18-94 and 87-MOP2-01. Two parallel, moderate, NW-dipping (65⁰) conductive plates were detected approximately 100 m below the deepest drilling in what is the most strongly sulphide-mineralized area of the Roger Au-Cu deposit system (see Figure 2 ). A shallow to moderate NE-plunge is interpreted for the conductors which matches the plunge direction of the area geology. Of particular interest is a very strong (500 siemens) off-hole conductive plate approximately 250-300 m NE of the eastern extremity of the survey. This anomaly aligns with a base metal exhalative horizon intersected in historical hole 1206-18-114, 300 m further to the northeast ( 1.73% Cu, 25.0 g/t Ag, 15.2 g/t Au over 0.7m ). This target constitutes a highest-priority base metal sulphide target to be drilled. The geometry and location of the conductors will be used to optimize drill targeting for the upcoming winter program.

SW Sector

BHEM survey work in this region (see Figure 2 ) was completed on drillholes 1206-04-19 and 1206-13-73, 77, 78 and 83 in an area of base metal sulphide exhalative horizons. Grades of 3.93% Cu, 50.0 g/t Ag, 3.7 g/t Au over 3.8m (BH 1206-18-73) and 3.6% Zn, 3.2% Cu, 124.0 g/t Ag, 27.0 g/t Au over 1.2m (BH 1206-13-75) from massive sulphide-bearing chloritic horizons were reported in historical drilling in the area.

The survey detected a weak to moderate off-hole formational conductive plate below the earlier drilling. Of particular interest is the observation that the conductivity of the plate strengthens towards the southwest of the survey area (125 siemens) and may be related to base metal sulphide bodies in that area.

Oblique 3-D images of the conductive targets identified by the survey work are present in Figure 1 & 2 and will aid in locating diamond drillholes for our Winter 2026 program.
