Rupert Resources Drills 26.8g/t Gold Over 2.0m and 11.6g/t Gold Over 5.0m Confirming a 500m Long Mineralised Trend at the Pahtavaara Mine

TORONTO / Jul 29, 2021 / Business Wire / Rupert Resources Ltd (“Rupert” or “the Company”, TSX-V: RUP) reports further drill results and geological interpretation from in-mine exploration drilling at the 100%-owned Pahtavaara mine in the Central Lapland Greenstone Belt, Finland.

Highlights

• Hole 120525 intersected 11.6g/t gold (Au) over 5.0m from 51m (35m vertical) confirming continuation of T-Vein mineralisation towards surface.
• High-grade mineralisation including 26.8g/t Au over 2m in hole 121469 and wider mineralisation including 3.7g/t Au over 12.4m in hole 121406 highlight both the grade and width present within the T-Vein mineralisation trend.
• Mineralisation at T-Vein now extends 500m, from surface in the down-plunge direction.

James Withall, CEO of Rupert Resources commented “These new results from the Pahtavaara mine are significant because they show the potential for near surface, potentially open-pit mineable material in immediate proximity to the Pahtavaara mine and mill. Importantly these results provide further evidence of a previously unidentified easterly plunge control on mineralisation. The Pahtavaara mine remains an important asset in the region, as one of only two permitted gold mills, and any new discoveries in the immediate vicinity could add significantly to mine life. Drilling will continue at the mine, Ikkari and our numerous other targets as part of our ongoing exploration program, with the goal of highlighting the geological and economic potential of the Pahtavaara Project in its entirety.”

New mine drilling

Further to the last reported mine drilling of 1,657m (results reported on Oct 20, 2020), 93 holes for a total of 6561.5m were drilled as part of the circa 10,000m resource expansion drilling program at the Pahtavaara Mine site (announced Oct 20, 2020). Headline drilling intercepts from the 2020-21 program are shown in table 1, and results from all 93 new holes reported in table 3.

The focus of resource expansion drilling was T-Vein, where a new geological interpretation envisaged an easterly plunging mineralised trend (figure 2). The drill program successfully delineated continuous mineralisation over a 500m easterly plunge between surface and 300m depth. This trend has only been the subject of sporadic previous mining.

This drill program successfully delineated mineralisation close to surface with hole 120527 intersecting 2.4g/t Au over 3.3m, only 11m below surface and less than 3m below the bedrock surface. Hole 120525 intersected 11.6g/t over 5.0m a further 28m down dip whilst hole 121501 intersected 2.8g/t Au over 9m a further 28m down plunge to the east. These results confirm continuity of a significant mineralised trend between surface and historic underground workings (figure 2).

At the centre of the plunging T-Vein trend, significant widths of mineralisation were encountered, including hole 121406 grading 3.7g/t Au over 12.4m, hole 121427 grading 3.6g/t Au over 11m, and hole 121431 grading 3.8g/t over 12m; all these intercepts represent over 75% the true width of mineralisation with the latter two over 90% true width.

Figure 2 shows intercepts from this drill program and those previously reported (May 21, 2020 and October 20, 2020) plotted on a long section to highlight the continuous nature of the mineralisation along the trend. Figures 3 and 4 show example cross-sections through the mineralisation trend, both close to surface and in the middle of the trend, highlighting the thicker intercepts found towards the centre of the trend. Locations for the cross sections are indicated on figure 2.

The new results are consistent with the revised geological interpretation at T-Vein. The application of this new interpretation to other mineralisation trends on the southern flank of the Pahtavaara Mine is underway, including testing new interpretations to the mineralisation plunge at Karoliina and Karoliina East.

Fourteen out of the 93 holes reported here are from the Karoliina target area. The Karoliina target shares a similar structural and lithological setting to T-Vein though the mineralisation present is typically lower grade. These new drillholes aimed to expand the resource through a portion of the deposit between 150-250m below surface but adjacent to existing underground infrastructure. By implementing the interpretations from T-Vein, mineralisation was successfully traced through this previously untested part of the deposit highlighted by hole 121449 grading 2.1g/t Au over 4m and hole 121453 grading 2.1g/t Au over 3m. Figure 5 shows these intercepts on a long section.

Results were also received from four holes targeting mineralisation above the Karoliina East Zone, a portion of the deposit that has been historically mined from underground, but which has seen very little exploration closer to surface. The short drill program successfully intersected mineralisation above the zone with hole 120518 intersecting 46.8g/t Au over 2.6m, 120517 intersecting 4.8g/t Au over 2.3m, and 120519 intersecting 1.3g/t Au over 3.0m.

Further results from the drilling close to surface at the Karoliina target are awaited and the work to update the mineral resource model to reflect these new results is ongoing.

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 licence package of some 509km². The Company acquired the project for 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.

The Pahtavaara Mine is an orogenic gold deposit hosted in an altered komatiitic sequence in the eastern part of the greenstone belt. Mineralisation is hosted by the predominantly pyroclastic, voluminous ultramafic volcanic rocks of the Sattasvaara komatiite complex (Savukoski group).

Mineralisation consists of structurally controlled sub-parallel lodes with steeply dipping ore shoots, comprising mostly free gold in quartz-dolomite vein stockwork. Mineralization is hosted predominantly by coarse-grained, non-schistose amphibole rocks with brittle dolomite ± quartz (± barite) veins, or biotite-talc (± chlorite) dominated schists with talc-carbonate ± pyrite ± magnetite veins, which are related to structural failure at the contact between the amphibolite rocks and the talc-chlorite schists. Coarse-grained amphibole dominated lithologies dip and plunge sub-vertically to the west-southwest within a wider, more diffuse, amphibole porphyroblast alteration domain which overprints the talc schists. Folding of the amphibole unit controls brittle fracture in hinges and associated gold mineralisation in places.
