 CALGARY, Alberta, Sept.  15, 2025  (GLOBE NEWSWIRE) -- Integral Metals Corp. (CSE: INTG | OTC: ITGLF | FSE: ZK9) (the “Company” or “Integral”)  is pleased to announce the completion of a comprehensive soil  geochemical dataset 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 dataset 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 five percent of  the dataset, 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 ppm to highs exceeding 69,900 ppm. Lead  ranged from 7 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 dataset 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 now begun a  detailed statistical and spatial analysis of the dataset, including  assessment of multi-element relationships and anomaly clustering.
 
 Paul  Sparkes, CEO 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.”
