Rupert Resources Provides an Exploration Update and Reports New Drilling From Heinä Central Including 57.9m Grading 1.2 g/t Gold and 0.3% Copper
Rupert Resources Ltd. (“Rupert” or “the Company”) provides an exploration update and reports new drill results from its ongoing exploration programme at Area 1, a 5km long highly prospective section of a regional domain-bounding structure, 20km of which is contained within Rupert’s 100% owned Pahtavaara Project in the Central Lapland Greenstone Belt, Finland (figure 1).

Since commencing exploration activities at Area 1 in January 2019, Rupert Resources has identified and drilled six new gold occurrences, including the significant scale Ikkari discovery. Base of till (“BoT”) sampling is continuing to identify further new gold anomalies that will be drill-tested in the months ahead. This release highlights several significant intercepts drilled at the end of 2020 as part of the continuing regional exploration program.
The exploration plan for the 2021 calendar year includes up to 60,000m of diamond drilling across the Pahtavaara Project including Ikkari, existing and new Area 1 targets and at the mine (figure 2).
Highlights
- Hole 120114 intersected 57.9m grading 1.2g/t gold (“Au”) and 0.3% copper (“Cu”) from 127m (99m vertical) including 11.8g/t Au and 0.2% Cu over 3m which includes 26.4g/t Au and 0.2% Cu over 1m at the Heinä Central target (1km of to the north of Ikkari, see figure 3).
- Hole 120116 intersected 20m grading 1.0g/t Au and 1.3% Cu from 225m downhole (166m vertical) at Heinä Central demonstrating the potential for significant copper mineralisation.
- Hole 120105 at Island North (located 2km to the northeast of Ikkari) intersected 2.2g/t Au over 15m, from 124m (95m vertical) including 4.9g/t Au over 5m. This hole is part of a program following up on high grade vein hosted mineralisation (249g/t Au over 0.5m) identified in early 2020.
- Hit Rate - 75% of drillholes assayed to date from Area 1 have yielded gold grades greater than a 0.4g/t Au nominal cut-off.
- Since work commenced in January 2019, 7,823 BoT samples have been taken with all six gold occurrences at Area 1 discovered beneath coincident BoT anomalies and structural targets identified from geophysics.
James Withall, CEO of Rupert Resources commented “The results reported today continue to highlight the district scale mineralisation potential at Area 1, which only represents around 5% of Rupert’s total 425km2 land package in Northern Finland. The success rate of drilling at Area 1 is very compelling, demonstrating the potential for a large gold mineralising system that we expect will continue to yield further new discoveries of scale. In 2021 we will continue with our target generation program as well as progressing our inventory of new discoveries at Area 1 (including Ikkari) and at the Pahtavaara mine to a resource. Metallurgical test work and environmental studies will run in parallel to ensure timely economic evaluations.”
Exploration update
Winter drilling conditions now allow access to all parts of Area 1 (figure 1). At Ikkari, drilling continues to progress, targeting depth extensions and systematically stepping out along the predicted strike, with the mineralised envelope still open to the east and west. Drilling will also recommence at Heinä South (located approximately 500m north west of Ikkari) where high-grade gold mineralisation (5.2g/t Au over 9.2m and 482g/t Au over 1m, see press release dated June 10, 2020) was drilled at the end of the winter drilling season in 2020. Heinä South has several untested BoT anomalies and the sampling coverage will be expanded to the south and west during the next two months. To date 39,078 metres have now been drilled at Area 1 in 169 holes including 19,645 metres at Ikkari in 62 holes, with results reported for 45 holes. Further results will be released as assays are completed.

Heinä Central
Today’s results further highlight the potential for broad well-mineralised zones of gold and copper. Holes 120014 and 120016 targeted strike orientation of lithologies at Heinä Central (~E-W trending, confirmed by orientation of bedding and foliation in core) to assess mineralisation associated with lithological contacts. The extent and orientation of structural zones, and of the multiple mineralised zones, have not yet been fully determined and sulphide mineralisation remains open to the northwest, north and east. The previous drilling targeted NW trending magnetics coinciding with a contact with a mafic intrusive with holes 119044 (1.4g/t Au and 0.5% Cu over 31m from 64m) and 119062 (3.3g/t Au and 1.5% Cu over 10.6m from 84m, including 12.3g/t Au over 2.0m and 1.8% Cu over 6.0m), demonstrating both the broad zones and high-grade potential of the target (figure 3). Preliminary metallurgical investigation indicates that conventional flotation can recover up to 90.4% of the gold and 99.5% of the copper.
Island North
The Island North target was initially identified from anomalous BoT samples of up to 6.5ppm with limited initial drilling demonstrating potential for very high grades (hole 120015 intersected 249g/t Au over 0.5m within a 10m mineralised fault zone). Follow up drilling reported here (hole 120105 – 2.2g/t Au over 15m from 124m) confirms gold mineralisation associated with brecciated quartz-carbonate-sulphide veins at lithological contacts within altered sedimentary units and further define the potential orientation of mineralisation in a broadly E-W trend.
Saitta
At Saitta, previous drilling (see release 26 February 2020) intersected gold mineralisation in a similar geological setting to the Ikkari discovery with highlights from prior drilling including 1.4g/t Au over 11m from 9m, in hole 120002. Limited follow up drilling of 751m in three holes has intersected further pyrite-hosted gold mineralisation, 0.8g/t Au over 10m from 115m in hole 120077, within the predicted trend, expanding the mineralised envelope at this target. Despite many geological similarities with Ikkari, strongly deformed structural zones have not yet been intersected at Saitta, and further interpretation of the data collected to date will facilitate further drill targeting.

Geological interpretation
All six discoveries in Area 1 have similar geological characteristics, that are typical of orogenic gold systems. Gold is hosted by altered sedimentary and volcanoclastic rocks, associated with quartz, quartz-carbonate veining and or sulphides within structurally deformed settings.
At Heinä Central, the multiple sulphide zones identified (25 to >50% pyrrhotite+chalcopyrite+pyrite) are hosted by cataclastic quartz-dolomite breccia within a sedimentary sequence that includes interbedded siltstone and carbonaceous shale. This sequence is intruded by intermediate dykes, and mafic intrusives are also present. Brecciation is associated with a broad, complex structural zone that is related to decoupling along lithological contacts and localised folding.
At Island North the gold mineralisation is hosted by sericite-albite altered sedimentary rocks, including carbonaceous shales, particularly at lithological contacts with mafic intrusives, and also occurs in association with quartz-sericite veins within carbonaceous shale.
At Saitta gold mineralisation associated with pyrite occurs within sedimentary rocks, close to the Kumpu Group contact.
About the Pahtavaara Project
The Pahtavaara Project is located in the heart of the Central Lapland Greenstone Belt, Northern Finland where the company owns the permitted Pahtavaara mine that is on active care & maintenance and within a contiguous licence package of some 425km2. The Company acquired the project for just USD $2.5m in 2016 and is undertaking exploration both at the existing mine and across the region to demonstrate the potential for significant economic mineralisation.
Area 1 comprises a large part of a structural corridor that lies between Kittilä Group allochthon to the north and the younger Kumpu Group basin to the south. The zone 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.
