Basin identifies structures associated with mineralization in projects in North Sweden
Important highlights
– Structural relogation of 48 historical drill holes on the projects of Virka and Bjorkberet completed
o Detailed structural records now available for 28 priority Historical drill holes of Bjorkberet, with 137 samples currently in the Laboratory for Multielement Analysis. Extra 71 samples from Bjorkberette Core are waiting for shipping to Laboratory for Analysis
o All historic drilling core of Virka has been transferred. Samples are waiting for shipping to the laboratory for sample preparation
o Mineralization structure trends clearly identified in the core; Associated change and mineral assembly (pending analysis results) will be used as a vector for future borehole targeting
– Pulp heralysis of 2 samples over detection limit (> 2.95 U3O8) by Fusion XRF of Bjorkberette 2024 Field Mapping Return Very positive results:
o bjk004: exceeded detection limits that again returned more than 5.9% U3O8 from Granite Kei sample with visible yellow oxide color at the basis of an access
O bjk008: Rhyolitic and fine -grained granite breeze with visible mineralization and yellow oxide color at the base of an access is returned to 5.4% U3O8 from Rhyolitic and Fine -grained granite
The director of Basin, Pete Moorhouse, remarked: “The results of the structural relogation and multielement -analysis results add a crucial modern interpretation of the variety of mineral systems that play in our North Sweden projects portfolio. The final ass bonding results in our Projecting result in our Projects Breeding in our Projects Breeding Birds in our Projects Breeding Birds in our Projects Breeding Birding Budgeting Beaching Beaching Beaching Inputs in Projects in Projects in Projects in Projects in Projects in Projects in Projects in Projects in Projects in Projects in Projects. is largely assured.
Data generating good quality data by relogating and sampling the available historical core is a cost-effective approach to unlock the full potential of the North Sweden project portfolio. ”
The results have now been received from the re-analysis of the two Bjork samples that have returned above Uranium mineralization (> 2.95% U3O8) that was previously reported in Basin’s ASX Release1 of 13 February 2025. No further analysis was completed on the other reported elements.
The company continues to promote structural release (figures 1 and 2) and sampling of historic drill holes in the Bjork, Rava and Virka projects with 48 drill holes that have been transferred from 101 total drill holes. A total of 137 samples are currently in the laboratory pending analysis. Basin recently acquired several projects in which limited government historical exploration of uranium mineralization identified; But rarely assessed polymetallic prospectivity, including rare earth, gold and basic metal opportunities.
Structural logging and sampling of historical core
Relogging and sampling continues with historic drilling cores for the North Sweden projects, with 101 drill holes from the combined project areas that have been established to date.
The primary focus of the Relogging program is to investigate the various mineralization systems that are identified by historical exploration and by recent field mapping, to study the structural framework to determine potential for blind mineralization and to investigate change that is known to be used to be a virgin interior.
Drill Core Research includes detailed geological and structural logging and detailed photography. These observations together with a radiometric core scan using a handheld Gamma-ray spectrometer (Exploranium GR-130 MinisPec) are used to define sample intervals to send to the laboratory for analysis.
Basin has completed the logging of all the holes identified from Virka, along with 28 priority drills from 39 at Bjork. There are currently 137 samples from Bjork as Laboratory from important intervals that analysis undergo. Core samples are analyzed with multielement analysis to continue to evaluate the potential for green energy metals at the North Sweden projects of the company.
The historical core investigated from the Bjork project usually includes a homogeneous leucocratic granite consisting of a maximum of 7% MAFIC components, including magnetite. Lithologies are more varied in the Virka core, mainly consisting of granite, amphibolite and porphyritic granite. Uranium mineralization joints as fracture/vein fillings and distribution on the core of both projects (Figure 1, Appendix 2). Localized intervals were registered with visible sphalerite (Figure 2) and nodular sulfides (Figure 1, Appendix 2*). Structural distortion observed in the bjork -core is almost always brittle, with a clear network of microfactures and adlets that consistently wear magnetite/hematite with visible uraninite (Figure 1, Appendix 2*); Small -scale Breccias and cataclasites are also noticed locally.
Re-analyzes of monsters bjk004 & bjk008 by fusion xrf
Of the twelve samples, Bjork gathered during the initial field exploration visit in Q4 2024, sent two samples, BJK008 and BJK004, values above the detection for uranium (> 2.95% U3O8) for the chosen as-analysis method ME-MS89L. Both samples were of boulders with visible yellow oxide color at the basis of an access.
The pulp of these samples were again analyzed by the laboratory using Fusion XRF (ME-XRF15B), the only other reliable high-quality uranium analysis method option that is available locally via ALS.
Reported analysis results (Figure 4 and Appendix 3 for details*):
– BJK008 returned 5.38% U3O8
o First test methods (MS-MS89L): U3O8> 2.95% (above detection limits), PB 1.39%, Fe 23.4%, 0.13% Treo (74% HREO)
o The monster was collected from a boulder with visible yellow oxide color at the basis of an access
– BJK004 returned to the detection limit for the second analysis technique U3O8> 5.9 % of a boulder with visible yellow oxide color at the basis of an access:
o Initial test methods (ME-MS89L): U3O8> 2.95% (above detection limits), PB 1.85%, 0.12% Treo (49% HREO), 522 ppm Mo
*While new analysis has returned the results above the detection limit for Monster BJK004, the company does not plant additional analyzes because of the high -quality nature of the sample.
Update about the proposed changes to Sweden in uranium exploration and mining
The Swedish government announced an investigation into the destruction of the uranium moratory in December 2024. The investigation recommends regulating uranium as a mineral concession within Swedish mineral law, so that its exploitation can be exploited like other natural resources. The findings of the investigation were submitted for consultation with authorities, municipalities and other stakeholders, including a public consultation period that ended on March 20, 2025. After the consultation, a legislative proposal will be presented to the Swedish parliament. If approved by the parliament, the proposed legislative changes are set to come into effect on January 1, 2026. The proposal is driven by the growing needs of Sweden for critical metals and minerals to support the green transition, as well as safety problems arising from the current geopolitan landscape.
