TORONTO--(BUSINESS WIRE)-- Rupert Resources Ltd (“Rupert” or the “Company”) today provides an exploration update from its properties in the Central Lapland, Northern Finland including new drilling results and interpretations from Heinä South (1km from the 4Moz Ikkari Project, see press release dated February 18, 2025) and from other targets along the 12km regional structure east-northeast from Ikkari (the “Rajala” line).

HIGHLIGHTS

• High-grade mineralisation continues to be intersected at Heinä South including 45.7g/t Au over 8m including 362g/t Au over 1m intersected in hole #125001.
• Additionally, to the north of the main trend, additional single metre high grade intercepts of 83g/t Au, 66g/t Au and 31g/t Au intersected in three separate drill holes. Multiple incidences of broader lower grade mineralisation are also evident.
• Induced Polarisation (“IP”) surveys alongside wide-spaced drillholes confirm the continuity of the structural and lithological setting that hosts the Ikkari Orebody for >7km along the ‘”Rajala Line” structure to the ENE.

Graham Crew, Chief Executive Officer of Rupert Resources said “We are encouraged by today’s results and the potential to add to the 4Moz resource inventory at Ikkari through continued drilling success at satellite discoveries. Exploration remains a core part of Rupert’s DNA and we continue to systematically generate, test and assess exploration targets applying our proven exploration methodology and economic criteria to ensure efficient utilisation of exploration expenditure.”

Heinä South

As reported previously, drilling in 2024 had delineated continuous lower grade mineralisation over down hole widths of up to 29m to the southwest of the previously discovered Heinä South gold occurrence, this was typified in #124001 1.1g/t Au over 24.50m (see press release February 8, 2024). In addition to this, very-high grade mineralisation was intersected to the north of this trend. Structural interpretation during the summer months hypothesized a WNW structural control to the high-grade mineralisation sub parallel to the drill direction. This was tested in early 2025 by drilling on a different orientation specifically to target the high-grade mineralisation (Figure 1).

Drilling recommenced at Heinä South in January 2025. Hole #125001 intersected 45.7g/t Au over 8m including 362g/t Au over 1m. To the north several narrow, high-grade, intersections were encountered with #125015 intersecting 83g/t Au over 1m, #125007 intersecting 66g/t Au over 1m and #125010 intersecting 31g/t Au over 1m (Figure 2).

Ikkari – Saitta – Mike Trend

A 13-line 26km IP survey (Figure 3) was undertaken during Autumn 2024 and followed up with widely spaced drilling, including several holes to depth, along the trend. The program has confirmed the presence of the same stratigraphy that hosts that Ikkari orebody along the >7km strike length and provided evidence for a high-strain zone, analogous in orientation and dip of that present at the Ikkari orebody, occurring at depth. These observations confirm the inherent prospectivity of this trend and will feed into more detailed targeting over the coming months (Figure 4).

Target Generation

To date, since December, >2000 base of till (BoT) samples have been taken as part of Rupert’s continued greenfield exploration program. BoT has focused on the Rajala area, 15km northeast from Ikkari and the recently acquired Sayna exploration permit, 20km northwest from Ikkari. These grassroots campaigns will form the basis of Rupert’s target definition work informing future drill programmes through the balance of 2025 and into 2026.

Review by Qualified Person

Mr. Craig Hartshorne, a Chartered Geologist and a Fellow of the Geological Society of London, is the Qualified Person responsible for the accuracy of scientific and technical information in this news release.

The majority of samples are prepared by ALS Finland in either Sodankylä or Outokumpu. Fire assays are subsequently completed at ALS Romania whilst multielement analysis is completed in ALS Ireland. A minority of samples are prepared by Eurofins Laboratory in Sodankylä and Fire Assay is carried out on site. A pulverised sub-sample is then sent to ALS Ireland for multi-element analysis. All samples are under watch from the drill site to the storage facility. Samples at both laboratories are assayed using 50g fire assay method with aqua regia digest and analysis by AAS for gold. Over limit analysis (>100 ppm Au) are conducted using fire assay and gravimetric finish. For multi-element assays, Ultra Trace Level Method by 4-Acid digest (HF-HNO3-HClO4 acid digestion, HCl leach) and a combination of ICP-MS and ICP-AES are used. The Company’s QA/QC program includes the regular insertion of blanks and standards into the sample shipments, as well as instructions for duplication. Standards, blanks and duplicates are inserted at appropriate intervals. Approximately five percent (5%) of samples have the pulp reject resubmitted for check assaying at a second laboratory.

Results presented include results from screen fire assay as indicated in Table 2. Screen fire assays were requested due to the presence of coarse gold in the drill core and were performed by ALS Romania. Screen fire assays involve the screening of 1kg at 106 microns to separate the sample into a coarse fraction (>106μm) and a fine fraction (<106μm). After screening, two 50g sub-samples of the fine fraction are analysed using the normal 50g fire assay method with aqua regia digest and analysis by AAS for gold. The entire coarse fraction is assayed to determine the contribution of the coarse gold using fire assay and gravimetric finish. The “total” gold calculation for the 1kg sample is based on the weighted average of the coarse and fine fractions and is reported for the indicated samples.

Base of till samples are prepared in ALS Sodankylä by dry-sieving method prep-41 and assayed for gold by fire assay with ICP-AES finish. Multi-elements are assayed in ALS laboratories in either of Ireland, Romania or Sweden by aqua regia with ICP-MS finish. Rupert maintains a strict chain of custody procedure to manage the handling of all samples. The Company’s QA/QC program includes the regular insertion of blanks and standards into the sample shipments, as well as instructions for duplication and external check assays.

Cautionary Note Regarding Mineral Resources and Mineral Reserves

Unless otherwise indicated, the scientific and technical disclosure included in this press release, including all Mineral Resource and Mineral Reserve estimates contained in such technical disclosure, has been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council on May 10, 2014 (the “CIM Definition Standards”). Readers are cautioned that Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all, or any part, of Mineral Resources will be converted into Mineral Reserves. Inferred Mineral Resources are Mineral Resources for which quantity and grade or quality are estimated based on limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. Inferred Mineral Resources are based on limited information and have a great amount of uncertainty as to their existence and as to their economic and legal feasibility, although it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. Inferred Mineral Resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves.
