Rupert Resources Extends Shallow High-Grade Mineralisation at Ikkari

07.06.2022  |  Business Wire

Rupert Resources Ltd. ("Rupert" or the "Company"), 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 that new drilling (figure 1) at its flagship Ikkari discovery has extended near-surface, high-grade mineralisation.

Ikkari has a National Instrument 43-101 mineral resource estimate of 49 million tonnes ("Mt") at 2.5 grams per tonne gold ("g/t Au") for 3.95 million inferred ounces (see Sept. 13, 2021 press release) 1. Over 45,000 metres ("m") of drilling has now been completed at Ikkari since its maiden resource statement (location of new holes see figure 1), focused on upgrading and exploring the limits of the Ikkari resource estimate.

Highlights

New drilling at Ikkari extends near-surface high-grade zone to the east (figures 2 and 3):

  • #122057 returned
    • 59m of 8.0g/t Au from 148m (116m vertical)
    • and 26m of 4.5g/t Au from 223m

In central Ikkari, further high-grade results were received, confirming widths of mineralised zones:

  • #122090 returned
    • 24m of 6.3g/t Au from 206m (173m vertical)
    • and 47m of 5.8g/t Au from 267m
    • and 29m of 1.9g/t Au from 349m
    • and 12m of 1.2g/t Au from 382m
  • #122091 returned
    • 49.5m of 3.6g/t Au from 184m (including 5m of 9.7g/t Au)
    • and 31.7m of 4.0g/t Au from 283m

Drilling at depth in the Ikkari deposit continues to confirm gold intercepts at the limits of September 2021's maiden resource estimate:

  • #122068 returned
    • 80m of 1.4g/t Au from 276m
    • and 13m of 3.7g/t Au from 540m (440m vertical)

James Withall, CEO of Rupert Resources commented "The new drilling at Ikkari continues to impress with more indications of near-surface, high-grade material in the eastern section of the deposit with the drilling providing yet further proof of Ikkari's characteristic exceptional continuity and potentially broad mining widths, which we expect to be captured in the preliminary economic assessment."

New Ikkari drill results and exploration update

Results from six new holes at Ikkari (figure 1) have further confirmed near-surface, high grade mineralisation as well as adding to the depth of the mineralised zone. These results, from holes drilled mostly from the northern side of the deposit, during winter, confirm widths of the mineralised zones and improve continuity of high grades across the main mineralised zone by demonstrating the low variance of grade distribution. For example, in the eastern part of the deposit, hole 122057 includes a substantial intercept of 8g/t Au over 59m from 116m below surface (figures 2 and 3), which improves on previously reported grades on this section, and in the central part of the deposit hole 122090 also returns a high-grade intercept of 6.3g/t over 47m from 173m vertical (figure 1).

Further drilling at depth in the deposit has also improved grades at the lower margins of the reported Resource estimation, with hole 122068 reporting 3.7g/t Au over 13m from 440m vertical (figure 2).

An updated resource and accompanying preliminary economic assessment will be completed in H2 2022. Approximately 75,000m of drilling is budgeted for the next twelve months targeting resource additions through satellites or extensions to Ikkari and elsewhere on Rupert's five regional target areas.

Regional exploration continues with nearly 30,000m drilled on targets, including Heinä Central and Heinä South, since September 2021.

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 ("Ga") old Savukoski group greenschist-metamorphosed mafic-ultramafic volcanic rocks, part of the Central Lapland Greenstone Belt ("CLGB"). 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.

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.

1 National Instrument 43-101 inferred mineral resource estimate ("MRE") for Ikkari of 49 million tonnes ("Mt") at 2.5 grams per tonne gold ("g/t Au"), for 3.95 million ounces ("oz") in total (see the technical report entitled "NI 43-101 Technical Report: Ikkari Project, Finland" with an effective date of September 13, 2021 prepared by Brian Wolfe, Principal Consultant, International Resource Solutions Pty Ltd., an independent qualified person under NI 43-101: the "Ikkari Technical Report").

The MRE has been estimated using the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") "Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines". It was calculated using the multiple indicator kriging method (MIK) and is classified as an inferred mineral resource as defined by the CIM. Numbers are affected by rounding. The MRE was reported using cut-offs of 0.6g/t Au for mineralisation potentially mineable by open pit methods and 1.2g/t Au for that portion that is potentially extractable by underground methods. The cut-offs were based on a gold price of US$1430/oz Au, with a 92% overall recovery and costs derived from benchmarks and first principles (see: the Ikkari Technical Report). Mineral Resources do not include Mineral Reserves and do not have demonstrated economic viability. There is no certainty that any part of the Mineral Resources will be converted to Mineral Reserves.
