HIGHLIGHTS

  • Maiden inferred mineral resource estimate for Ikkari of 49 million tonnes (Mt) at 2.5 grams per tonne gold (g/t Au) for 3.95 million ounces (see Table 1). Resource estimate based on over 36,000 metres (m) of drilling to the end of June.
  • Resource timeline - Discovery hole to multi-million ounce baseline resource in less than 18 months.
  • High-quality ounces - Cohesive deposit comprised of broad intervals of strong and consistent gold mineralisation.
  • Maintaining momentum - Over 28,000m drilling in remainder of 2021 and an estimated 62,000m budgeted during 2022 - 60% focused on upgrading and expanding Ikkari resource with remainder to ongoing regional program.
  • Resource growth potential - Ikkari remains open at depth and along strike.
  • High grade potential - New infill drilling (not included in MRE) includes 5.4g/t Au over 122.3m from 241.7m in infill hole 121070,including 16.9 g/t Au over 11m from 286m and 10.6 g/t Au over 10m from 322m.
  • Updated MRE and preliminary economic assessment (“PEA”) planned for mid-2022.

James Withall, CEO of Rupert Resources commented: “Today’s maiden resource confirms Ikkari as a multi-million-ounce gold discovery whose value we are unlocking at an accelerated pace. The deposit’s exceptional continuity and proximity to surface, together with the outstanding performance of our Finnish team has allowed us to deliver an initial resource less than eighteen months from the discovery hole, approximately half the industry average. We believe the demonstrated size, grade, cohesive mineralisation and growth potential, combined with non-refractory metallurgy and proximity to infrastructure, positions Ikkari as one of the most high-quality advanced exploration-stage assets of recent years.”

The mineral resource estimate for Ikkari is reported in accordance with NI 43-101 and has been estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) “Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines”. This mineral resource estimate was calculated using the multiple indicator kriging method (MIK) and is classified as inferred mineral resource as defined by the CIM. Numbers are affected by rounding. The estimate 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 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 as defined in NI 43-101).

The MRE was modelled utilising an initial geological interpretation of the deposit, following a review of all available data that has been collected since discovery in April 2020 and based on over 36,000m of drilling completed by Rupert up to the end of June 2021. Further work to optimize potential extraction methods and cut-off grades will be undertaken as part of the PEA expected to be completed along with an update to the MRE in mid-2022.

MAINTAINING MOMENTUM

2021/22 Gold Growth Program

Exploration and definition drilling is ongoing, and the deposit remains open to depth and along strike. A further 15,000m to 20,000m of additional drilling is recommended to reduce drill spacing from 80m x 60m to 40m x 30m, which is aimed to be sufficient to upgrade a portion of the existing MRE classification from inferred to measured and indicated categories. Rig capacity capable of drilling a budgeted 90,000m to the end-calendar 2022 has been contracted. Approximately 60% of drilling will be focused on upgrading and expanding the Ikkari resource estimate, with the remainder allocated to a regional program targeting potential satellite orebodies and new discoveries of scale.

At Ikkari infill drilling sections are being completed across the deposit, as well as targeted deeper holes, that will contribute to the anticipated 2022 update of the MRE. To date, approximately 39,000 metres have been drilled at Ikkari. In addition, drilling is underway at other regional prospects as part of the continuing new target generation program and resource definition of potential satellite deposits such as Heinä Central.

New drilling - high grade infill and encouraging step-out drilling

Further drilling reported today, but not included in the Ikkari MRE except where indicated, demonstrates the potential for resource uplift through infill and extension drilling as part of the PEA work program.

New infill drill results confirm further continuity of the high-grade zone, including:

  • 5.4 g/t Au over 122.3m from 241.7m, including 16.9 g/t Au over 11m from 286m and 10.6 g/t Au over 10m from 322m, in hole #121070.
  • 7.3 g/t Au over 21m from 355m, in hole #121068
  • 14.7g/t Au over 8.3m from 156m and 2.1g/t over 52m from 243m, in hole #121069

In the central part of the deposit, the deepest hole to date intersected mineralisation at a vertical depth of 740m (#121036: 1.2 g/t Au over 38m from 797m, including 3.0 g/t Au over 8m from 825m). This mineralisation suggests vertical continuity to this depth, although some 350m of depth extent remains untested between the #121036 intercept and the closest overlying intersection (#121021: 3.3 g/t Au over 37m from 517m at 400m vertical). Upcoming drilling will assess this zone and continue to extend downwards.

In addition, recent drilling results in the eastern extents of the current Ikkari deposit has added mineralisation at depth and extended the strike to over 800m. Hole #120159 intersected 2.3 g/t Au over 60m from 415m at ~350m vertical depth. Drilling has extended the mineralised trend eastwards, in #121066 which intersected 1.2 g/t Au over 16m from 386m, including 9.2 g/t Au over 1m, over 80m to the east of the closest mineralised intercept.

IKKARI GEOLOGICAL DESCRIPTION

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 Ga old Savukoski group greenschist-metamorphosed mafic-ultramafic volcanic rocks, part of the 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.
