INTEGRAL METALS CORP. ANNOUNCES COMPLETION OF SOIL GEOCHEMICAL DATASET AT THE KAP PROJECT

Integral Metals Corp. has completed a comprehensive soil geochemical data set at its KAP project, focused on the Main showing and surrounding area. This follows the completion of sample collection (see previous announcement on June 12, 2025).

The program emphasized B-horizon soils, with a total of 2,164 soil samples collected to ensure consistency and minimize surface contamination. Samples were logged for field attributes such as horizon, depth, colour, moisture and texture, creating a data set that integrated both geochemical and environmental context. Laboratory assays were performed for a suite of elements. Zinc and lead were prioritized, with values reported as best consolidated determinations across analytical methods. Quality assurance was maintained by inserting duplicate samples and certified reference standards, representing more than 5 per cent of the data set, to ensure reproducibility and analytical consistency.

Preliminary review of the data underscores the strength of the geochemical footprint at the Main showing on the project. Zinc values ranged from a background of approximately 15 parts per million to highs exceeding 69,900 ppm. Lead ranged from seven ppm to a maximum of 20,100 ppm. Supporting pathfinder elements included cadmium, typically near 0.5 ppm, but reached more than 350 ppm, and thallium, which was consistently detected above background in association with elevated lead. Barium concentrations extended up to 7,800 ppm while strontium exceeded 1,000 ppm in certain places, suggesting variability in carbonate and barite influence.

This new data set has established a baseline for the geochemical character of the Main showing and reaffirms the ability of soil sampling to detect the mineralization present on the property. The company has begun a detailed statistical and spatial analysis of the data set, including assessment of multielement relationships and anomaly clustering.

Paul Sparkes, chief executive officer of Integral Metals, commented: "This is the most comprehensive soil survey ever completed at KAP. To see such highs for zinc and lead gives us real confidence in the scale and strength of the Main showing. This program provides us with a solid geochemical footprint to build on, and we are excited to move forward with the detailed interpretation that will define our next round of drill targets."
