District Metals Corp., a junior explorer focused on uranium and polymetallic projects, has wrapped up an intensive reconnaissance program on its wholly owned Sågtjärn Property in Jämtland and Västernorrland Counties, Sweden. The work followed a 2025 UAV-based radiometric and magnetic survey that highlighted several anomalous zones, prompting a ground-based verification campaign that began after the September 3, 2025, announcement of the airborne results.
The field effort combined traditional mapping with modern handheld instrumentation. Surveyors recorded radiometric readings at 163 stations using an Exploranium GR-110 scintillometer, while also logging geological contacts and structural observations. In parallel, a team collected 32 rock and boulder samples from outcrops and surface deposits for laboratory analysis at ALS Geochemistry in Sweden and Ireland.

Survey design and data collection
The reconnaissance grid was intentionally aligned with the strike of the principal radiometric anomalies identified from the aerial survey. By walking transects across both the pegmatite and granite intrusions that cut the surrounding metamorphic host, the crew could directly compare handheld counts with the UAV-derived signatures. The handheld scintillometer measured gamma radiation in real time, allowing the team to prioritize zones with the strongest natural emission for sampling.
Geochemical sampling results
Laboratory analysis converted raw uranium concentrations to U₃O₈ equivalents (U₃O₈ = U × 1.1792). Several samples far exceeded the 500 ppm cutoff used to flag noteworthy mineralization. Highlights include a boulder with 1,179 ppm U₃O₈, another returning 3,538 ppm U₃O₈, and a gneiss fragment that measured an impressive 3,656 ppm U₃O₈. A concise table of the highest results is presented below:
| Sample | U₃O₈ (ppm) | Co (ppm) | Cu (ppm) | Mo (ppm) |
|---|---|---|---|---|
| M305451 | 1,179 | 5 | 1 | 407 |
| M305453 | 1,019 | 7 | 115 | 151 |
| M305454 | 3,538 | 15 | 169 | 43 |
| M305463 | 614 | 2 | 37 | 356 |
| M305464 | 2,594 | 4 | 33 | 597 |
| M305465 | 2,123 | 5 | 1 | 194 |
| M305476 | 812 | 6 | 743 | 2,710 |
| M305478 | 3,656 | 54 | 245 | 2,320 |
| M305479 | 1,769 | 9 | 955 | 13 |
| M305480 | 1,651 | 333 | 1,800 | 5,250 |
Extent and grade of uranium mineralization
Mapping revealed that the uranium-bearing pegmatites are not confined to the historic Sågtjärn deposit. Instead, mineralized bodies extend for roughly 2 km along strike, reaching both northwest and southeast of the area previously drilled by the Geological Survey of Sweden (SGU). Boulders located up to 1.5 km beyond the historic drill pattern still returned values above 1,000 ppm U₃O₈, indicating that the mineralized system likely continues beyond the known limits.
In addition to the pegmatite-hosted zones, silicified gneiss in the north-western 101-license and the adjoining Hammarmyran area displayed consistent enrichment. Boulders from these gneissic zones produced uranium concentrations from 1,019 ppm up to 3,656 ppm U₃O₈, suggesting a pervasive hydrothermal alteration halo that may be as significant as the primary intrusive bodies.
Associated base and critical metals
The reconnaissance program also highlighted a suite of by-product elements. South of the Staverberget Occurrence, a boulder exhibited a molybdenum content of 5,250 ppm Mo, while a separate gneiss sample delivered 333 ppm cobalt and an extraordinary 1,800 ppm copper. These ancillary grades reinforce the view that the Sågtjärn system is polymetallic in nature, with uranium acting as the primary commodity but accompanied by valuable critical metals.
Because the Staverberget Occurrence lies within the adjacent Sågtjärn 102 licence, the presence of copper-molybdenum mineralization dovetails with historic mining interest in the area, which once reported copper-molybdenum-gold boulders and modest uranium values. The new data therefore resurrects the possibility of a combined uranium-base-metal project.
Outlook for further exploration
Garrett Ainsworth, President and CEO of District Metals, expressed optimism: “We are very encouraged by the results from our reconnaissance program at our Sågtjärn Property, which have identified widespread uranium mineralization across multiple areas of the Property, including significant uranium values in both pegmatites and the surrounding gneiss.” He added that the discovery of mineralized boulders extending roughly 2 km beyond the historic deposit “provides compelling targets for follow-up exploration.”
The company plans to prioritize the high-grade zones identified in this campaign for targeted drilling, with an emphasis on testing the continuity of both the primary uranium system and the ancillary molybdenum-cobalt-copper enrichments. Should subsequent drilling confirm the inferred resource, the Sågtjärn Property could become a critical component of District’s broader Swedish portfolio, complementing its flagship Viken project.
