Following a focus during the prior winter drilling season on infill and project drilling required for the PFS and EIA, exploration has recommenced on the most prospective areas of Rupert’s land package. Figure 1 shows the location of the new drilling in addition to all assays over 0.4g/t Au achieved over the past five years in the close proximity to Ikkari including the Hein? South trend.
Hein? South was the first gold occurrence to be discovered in Area 1 in 2019. Drilling has now confirmed a strike of more than 1000m with mineralisation across a 200m wide corridor. Hein? South contains the highest-grade intercepts drilled in Area 1. Follow-up drilling continues.
Today’s drill results are part of the broader "West of Ikkari" drill campaign that is based on an updated structural interpretation of the area. Drilling targeted untested extensions that were previously overlooked due to a lack of base of till anomalism. The exploration team continue to evaluate all the data we have collected in the last five years together with a new drone-based aerial magnetic survey and our evolving geological understanding to prioritise the most prospective targets in the key winter drilling season.
Geological interpretation
Gold mineralisation in the west of Hein? South is associated with multi-phase sulphide mineralisation consisting of pyrite+-pyrrhotite+-chalcopyrite, principally occurring as the matrix to an earlier brecciated (iron)-carbonate phase. The earlier veins occur primarily within altered carbonaceous sediments folded between more homogenous gabbroic units. Gold mineralisation in the east of Hein? South is hosted within quartz-pyrite and massive pyrite veins and as lenses, as part of a stockwork of quartz-carbonate veins. Zones of massive pyrite contain the highest grades (>10g/t Au) with disseminated sulphide zone containing anomalous (<0.5g/t) gold. Early quartz-carbonate veins are overprinted by extensional veins that include coarse-grained pyrite and form sub-parallel trends, broadly related to lithological contacts between sediments and mafic-intermediate intrusives, although mineralisation also occurs within both lithologies. Further drilling is required to allow a resource to be published on the occurrence.

Review by Qualified Person, Quality Control and Reports
Craig Hartshorne, a Chartered Geologist and a Fellow of the Geological Society of London, is the Qualified Person, as defined by National Instrument 43-101, responsible for the accuracy of scientific and technical information in this news release.
The majority of samples are prepared by ALS Finland in either Sodankyl? or Outokumpu. Fire assays are subsequently completed at ALS Romania whilst multielement analysis is completed in ALS Ireland or Sweden. A minority of samples are prepared by Eurofins Laboratory in Sodankyl? 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 for Hole 124006 include results from screen fire assay as indicted 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 Sodankyl? 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.

1 November 2023 Updated Mineral Resource Estimate for the Ikkari Project.
The Mineral Resource Estimate for the Ikkari project has been prepared in accordance with NI 43-101 and following the requirements of Form 43-101F1. The methodology used to determine the Mineral Resource Estimate is consistent with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Estimation of Mineral Resource and Mineral Reserves Best Practices Guidelines (November 2019) and was classified following CIM Definition Standards for Mineral Resources & Mineral Reserves (May 2014). Readers are cautioned that Mineral Resources are not Mineral Reserves, and do not demonstrate economic viability. There is no certainty that all, or any part, of this Mineral Resource will be converted into Mineral Reserve. 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. Numbers may be affected by rounding.
The QP for the Ikkari Mineral Resource estimate is Mr. Brian Thomas, P.Geo., an independent QP, as defined under NI43-101 and an employee of WSP Canada Inc. based in Sudbury, Ontario, Canada.
The effective date of the 2023 Mineral Resource Estimate for Ikkari is 24th October 2023. The Mineral Resource Estimate at Ikkari is interpolated using Ordinary Kriging (OK) and is reported both within a Whittle optimized open pit shell and as a potential underground operation outside that. Underground mineral resources are constrained within the estimation domains to meet the RPEEE criteria for UG mining. The Mineral Resource Estimate at Ikkari is reported using a cutoff grade of 0.4g/t Au for mineralisation potentially mineable by open pit methods and 0.9g/t Au for mineralisation potentially extractable by underground methods. The open pit and underground cut off-grades are calculated using a gold price at $1700 per ounce; 95% Au Metallurgical recovery; open pit mining costs at $2.9/t; underground mining cost at $29/t; process costs at $11.3/t; G&A, Rehab and Closure $4.8/t and a royalty of 0.75%. The calculated cutoff grade is rounded up to 0.4g/t for reporting. The calculated underground cutoff grade is rounded up to 0.9g/t.
