Integral Metals Corp. Provides Comprehensive Analysis of Soil Geochemical Survey at the KAP Project

Over 2,000 soils analyzed; 818 B-horizon samples returned multiple anomalies with scores up to 11

CALGARY, Alberta, Oct. 01, 2025 (GLOBE NEWSWIRE) -- Integral Metals Corp. (CSE: INTG | OTC: ITGLF | FSE: ZK9) (the “Company” or “Integral”) is pleased to report the completion and compilation of its 2025 soil geochemistry survey at the KAP Project, located in the Mackenzie Mountains, Northwest Territories. The program was designed to systematically evaluate near-surface geochemical responses in the vicinity of the Main Showing and to provide a dataset to guide future exploration.

The 2025 program collected a total of 2,164 soil samples, of which 2,040 were B-horizon soils, the material most suitable for detecting subtle geochemical variations. Sample preparation was carried out by ALS Canada Ltd. in Yellowknife, Northwest Territories, where soils were screened to -180 µm and pulped. Analytical work was performed at ALS Canada Ltd. in North Vancouver, British Columbia, using four-acid digestion followed by ICP-MS (ME-MS61L) and ore-grade ICP-AES methods (ME-OG62, Zn-OG62) to provide a broad multi-element suite, including zinc, lead, cadmium, thallium, barium, and strontium. Comprehensive quality assurance and control protocols were implemented, with the insertion of 174 field duplicates and 117 certified reference materials, which showed reproducibility and plotting within acceptable limits for zinc, lead, cadmium, and other key elements.

Figure 1 presents the distribution of anomaly scores across the soil survey grid. To evaluate anomalies, the Company applied a composite anomaly scoring system based on twelve independent geochemical criteria, including single-element thresholds and element ratios. Scores were calculated for all 2,040 B-horizon samples, of which 1,222 samples returned zero or single anomalies and were considered background. The remaining 818 samples showed two or more anomalies, with composite scores ranging from 2 to 11. Two samples reached a maximum score of 11, representing less than 0.1% of the dataset, while 128 samples (6.3%) recorded scores of 7 or higher. Much of the high-scoring samples were concentrated in the immediate vicinity of the Main Showing, with additional clusters following trends elsewhere in the grid.

“We now have a clear dataset that highlights areas of interest around the Main Showing. These results give us a strong foundation to build from as we plan the next stage of exploration,” said Paul Sparkes, CEO of Integral Metals.

The Company will now integrate the soil geochemical dataset with existing geological mapping, drilling, and geophysical surveys. Follow-up exploration will focus on zones where consistently high anomaly scores overlap with structural features, with the objective of defining and prioritizing drill targets.
