Rupert Resources Reports Initial Underground Sampling Results Including Record 3,100g/t Over 0.5m

James Withall, Chief Executive of Rupert Resources said “The initial results of the underground sampling programme are extremely encouraging and show the potential for near mine resource additions at Pahtavaara. The ongoing underground sampling combined with assaying of unsampled core is equivalent to around 10,000m of diamond drilling which Rupert is able to complete on a low cost basis. Beyond the mine limits Rupert has an extensive 2018 fieldwork plan based on our historic data review, results from 2017 and a new regional structural interpretation that utilised our detailed UAV aeromag survey. We have also applied for a further 65km² contiguous ground located between Pahtavaara and the two major base metals deposits in the region.”

Initial results from underground sampling

Rupert is undertaking a comprehensive underground sampling program utilising the 35km of existing underground infrastructure to validate the geological model and potentially expand the resource at Pahtavaara. Results have now been received from 942 underground channel samples with 40 yielding gold grades of over 0.5g/t Au (see Tables 1 and 2). The program has been designed to sample up to 5,000m of underground development thoughout the vertical extent of the resource and across all the main mineralised zones.

Samurai
A group of samples in the Samurai zone at the -120 level (300m from surface) indicate the 400m strike extent mined in the upper levels of the mine may continue at depth. The historic mining at depth was constrained by the lack of drilling data, focussing on an ever reducing strike length as shown in Figure 1 below. The results from sampling of -120 level development drifts demonstrate the potential for a 60m south western extension from the historically mined stopes. Of particular note channel sample 818020 intersected 2m grading 11g/t and a separate chip sample (818019_4) from the same structure assayed 3,100g/t Au over a 0.5m interval, the highest gold assay value recorded at Pahtavaara. The area to the southwest of this lacks drilling and will be a target of programs planned to follow up this work.

NFE

As previously reported on 1 March 2018, underground sampling of a structure at the -150 level (400m below surface) in the existing decline yielded assays of 3.5g/t Au (817011_1), 26.2g/t Au (817011_2) and 4.9g/t Au (817011_4). Rupert maintains that this structure may be the NFE zone at depth in an area with no previous drilling between the historically mined Samuari and DB plunge zones.

The intervals presented in Tables 1 and 2 represent sampling widths and are not representative of true width of mineralisation.

2018 regional fieldwork

The Company has recently completed the consolidation of all historic geological and geochemical information covering our extensive licence areas into our inhouse database. Further, we will have completed the last areas of our detailed UAV magnetic surveying by the end of May. An updated regional geological and structural interpretation is well advanced and key areas of the licence package have now been prioritised. The 2018 summer fieldwork will begin in early June with six additional geologists joining the team to undertake an extensive regional mapping and sampling programme. This will include followup work at the Valimaa and Saitta targets identified last year through boulder and outcrop sampling along with the known occurrences at Koppelokangas and Hookana. Near mine exploration will also continue with base of till (“BOT”) drilling planned to followup results from the ionic leach sampling, heavy mineral sampling and drilling completed to date at the Liikamaa and Paskamaa targets in the Western Extension area (see figure 2).

Expanded licence area

Rupert has applied to expand its contiguous licence area in the Central Lapland Greenstone Belt by 30% to 290km². The new area extends Rupert’s position eastwards towards the two significant base metals deposits in the region operated by Boliden and Anglo American. The expanded area also extends coverage of the significant East - West structure that hosts Pahtavaara (see figure 3).

Review by Qualified Person, Quality Control and Reports

In compliance with National Instrument 43-101, Mr. Mike Sutton, P.Geo. is the Qualified Person who supervised the preparation of the scientific and technical disclosure in this news release. Samples are assayed by CRS/Actlabs Finland at Takatie 6, 90440 Kempele Finland, who have ISO9001 sample prep and ALS Minerals at Sodankyla, Finland and Pitea, Sweden. All samples are under watch from the drill site to the storage facility. Samples are assayed using cyanide leach methods with AAS detection of Au. 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 lab with the results averaged and intersections updated when received.
