Rupert Resources Ltd (TSX-V:RUP) (OTCQX:RUPRF) a company advancing the multi-million-ounce Ikkari gold deposit and new regional discoveries at the company’s 100% owned Rupert Lapland Project in Northern Finland, is pleased to announce new drilling from its Ikkari and Heinä South discoveries (figures 1 and 2).
Ikkari has a National Instrument 43-101 inferred mineral resource estimate of 49 million tonnes at 2.5 grams per tonne gold for 3.95 million ounces (see Sept. 13, 2021 press release) 1. Over 44,000 metres of drilling has now been completed at Ikkari since the maiden resource statement in September 2021 (location of new holes see figure 3), focused on upgrading and expanding the Ikkari resource estimate. Elsewhere, regional exploration continues with around 25,000m drilled on targets excluding Ikkari since September 2021.
New drilling at Ikkari extends to the west a previously identified zone of mineralisation at depth (figure 4a):
In central Ikkari, further high-grade results were received, and mineralisation was intersected at depth beyond the limits of previous drilling (figure 4b):
Infill drilling in the west of the Ikkari deposit continues to confirm broad gold intercepts from surface (beneath till), as well as at depth at the margin of September 2021’s maiden resource estimate):
Drilling at Heinä South, 300m south of the main Heinä South trend and 800m northwest of Ikkari (figure 5), has intersected the following new mineralisation:
James Withall, CEO of Rupert Resources commented “The new drilling at Ikkari continues to expand the mineralised envelope with the infill drilling undertaken this winter season essential to improving resource confidence and maintaining the permitting timeline for the project. We continue to increase our understanding of the broader mineralising system through drilling and a recently completed geophysical survey. This will inform our next round of step out drilling at Ikkari and our exploration programmes to make further discoveries of scale in the region. Ikkari remains the cornerstone discovery in a potential new mining camp in a tier one jurisdiction.”
New Ikkari drill results
Results from a further 18 holes (figures 1 and 2) continue to define broad mineralised zones, from surface, within the Ikkari orebody. A further 26 holes for over 8,000m remain pending. New results are mostly from the west of the deposit and demonstrate consistently mineralised intercepts at shallow depths e.g. #122066 returned 72m of 2.2g/t Au from 10.4m (9m vertical, sub-crop under till cover) as well as identifying deeper zones of mineralisation e.g. 47m of 1.9g/t Au from 168m, suggesting continuity to depth. Similarly, hole #122031 returned 30m of 2.8g/t Au from 471m (378m vertical).
Hole 122071, in the central part of the deposit confirms the main high-grade zone (33m of 6.5g/t Au from 299m) and further extends mineralisation to depth in the south (16m of 3.0g/t Au from 445m, 413m vertical and 6m of 2.0g/t Au from 503m, 465m vertical). These results extend the mineralised zone by up to 80m depth on this section.
New Heinä South drill results
At Heinä South, infill drilling along the 1km long mineralised trend further confirms mineralisation, with results from #122050 of 7m of 4.5g/t Au from 153m, #122063 of 4m of 4.0g/t Au from 112m and 3m of 2.1g/t Au from 205m, and hole #122054 with results of 5m of 2.7g/t Au from 109m.
A further 300m to the south of the Heinä South trend, initial results from a second, similarly-mineralised zone, parallel to the trend, indicate multiple mineralised zones. #122072 returned 2m at 4.9 g/t Au from 131m, 15m at 1.1 g/t Au from 142m and 3m at 2.5 g/t Au from 204m (figure 5). Results from several additional holes in this area are still pending.

Geological interpretation of Ikkari
Ikkari was discovered using systematic regional exploration that initially focused on geochemical sampling of the bedrock/till interface through glacial till deposits of 5m to 40m thickness. No outcrop is present, and topography is dominated by low-lying swamp areas.
The Ikkari deposit occurs within rocks that have been regionally mapped as 2.05-2.15 billion years old Savukoski group greenschist-metamorphosed mafic-ultramafic volcanic rocks, part of the Central Lapland Greenstone Belt. Gold mineralisation is largely confined to the structurally modified unconformity at a significant domain boundary. Younger sedimentary lithologies are complexly interleaved, with intensely altered ultramafic rocks, and the mineralized zone is bounded to the north by a steeply N-dipping cataclastic zone. In general, alteration and structure appear to be sub-vertical, with lithologies generally dipping ~70 degrees north.
The main mineralized zone is strongly altered and characterised by intense veining and foliation that frequently overprint original textures. An early phase of finely laminated, grey ankerite/dolomite veins is overprinted by stockwork-like irregular siderite ± quartz ± chlorite ± sulphide veins. These vein arrays are often deformed with shear-related boudinage and in situ brecciation. Magnetite and/or haematite are common, in association with pyrite. Hydrothermal alteration commonly comprises quartz-dolomite-chlorite-magnetite (±haematite). Gold is hosted by disseminated and vein-related pyrite. Multi-phase breccias are well developed within the mineralised zone, with early silicified cataclastic phases overprinted by late, carbonate- iron-oxide- rich, hydrothermal breccias which display a subvertical control. All breccias frequently host disseminated pyrite, and are often associated with bonanza gold grades, particularly where magnetite or haematite is prevalent. In the sedimentary lithologies, albite alteration is intense and pervasive, with pyrite-magnetite (± gold) hosted in veinlets in brittle fracture zones.
Geological interpretation of Heinä South
Mineralisation at the Heinä South prospect is covered with up to 10m of transported glacial till with restricted access in winter due to low lying wet ground conditions. Gold mineralisation is associated with multi-phase pyrite within quartz-pyrite and massive pyrite veins and lenses, as part of a stockwork of quartz-carbonate veins. Zones of massive pyrite contain the highest grades (up to 10 – 40g/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.
About the Rupert Lapland Project
The Rupert Lapland Project is located in the epicentre of the Central Lapland Greenstone Belt, Northern Finland, where the company has made six new discoveries including the high quality Ikkari Project with an inferred mineral resource estimate of 49Mt at 2.5 g/t gold for 3.95 million ounces1. The Rupert Lapland Project also holds the permitted Pahtavaara mine and mill (on active care & maintenance) within a regional land package of some 735km2. The Company acquired the project for USD2.5m in 2016 and is undertaking exploration both at the existing mine and across the region to demonstrate the potential for significant economic mineralisation. The Ikkari deposit and five other discoveries are located in a structural corridor that lies between the Kittilä Group allochthon to the north and the younger Kumpu Group basin to the south. The mineralised area is dominated by large E-W to ENE trending faults which have controlled broad to isoclinal folding within the sediment-dominated (Savukoski Group) rock package. A complex network of cross cutting structures has focused multi-stage fluid flow, with gold mineralisation associated with massive to fine-grained disseminated sulphides and concentrated at favourable structural intersections.

Samples are prepared by ALS Finland in Sodankylä and assayed in ALS laboratories in Ireland, Romania or Sweden. All samples are under watch from the drill site to the storage facility. Samples are assayed using fire assay method with aqua regia digest and analysis by AAS for gold. Over limit analysis for >10 ppm Au is conducted using fire assay and gravimetric finish for assays over >100ppm Au. For multi-element assays, Ultra Trace Level Method by 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 the pulps and rejects are sent for check assaying at a second laboratory.
