Rupert Resources Drills 3.0 G/t Gold Over 121.3m Including 5.5g/t Over 50m Expanding Higher Grade Central Section at Ikkari With Depth Extended on All Sections
Rupert Resources Ltd. reported new drill results from its Ikkari prospect, the focus of its ongoing 60,000m exploration programme at the 100% owned Pahtavaara Project in the Central Lapland Greenstone Belt, Finland. The mineralised strike length at Ikkari is now at least 650m in total with mineralisation on all sections intersected to a depth of 300 to 500m. The drilling increases maximum intersected vertical depth of mineralisation by 75m to 480m in the east (hole 120119) and by 100m to 320m in the west (holes 120100 and 120122). In the central section, the higher grade mineralised zone now extends to 320m depth within a broader mineralised envelope of almost 400m depth. New results reported from Ikkari continue to expand the mineralisation envelope. In the central part, broad, high-grade intercepts in hole 120123 further define the zone of high-grade mineralisation with 3.0g/t Au over 121.3m from 110.7m, including 5.5g/t Au over 50m in the upper part of the hole, infilling the high-grade zone, and 1.8g/t Au over 80m from 276m (250m vertical) and 1.3g/t Au over 40m from 378m (343m vertical) extending the mineralised depth in the central section of Ikkari to 380m vertical. Notably, the combined uncut down hole intercept of the three zones yields 1.9g/t Au over 307m. In the west, scissor holes 120100 and 120122 both intercepted multiple mineralised zones, (120122 – 1.1g/t Au over 70m from 194m, including 16.4g/t Au over 1m) further defining a broad mineralised envelope, which extends the mineralisation to over 320m vertical depth on this section (120122 – 1.3g/t Au over 23m from 421m). Further west, hole 120121 also intersected a broad mineralised envelope that includes 1.4g/t Au over 46m from 155m and 2.5g/t Au over 13m from 279m. This hole has recently been extended with results pending. In the east, holes 120119 and 120120 targeted deeper mineralisation beneath previously reported intercepts in this area and demonstrate continuity of the mineralised structure to 480m vertical depth, with 3.1g/t Au intersected over 7m, from 546m in hole 120119. Even further to the east, hole 120107 intersected 1.0g/t Au over 32m from 351m (310m vertical), indicating continuation of mineralisation along strike. Holes 120104, 120106 and 120109 failed to reach target depth due to adverse ground conditions. Ikkari remains open in both directions along strike (with gold anomalism identified by BoT drilling extending to at least 1km) and at depth, with step-out drilling also indicating potential for further mineralisation to the north and south. Drilling continues to progress, targeting strike and depth extensions with infill drilling also planned that will contribute to a resource estimation later in the year. To date, 20,386 metres have been drilled at Ikkari in 62 holes, with results reported for 52 holes. Drilling is also ongoing at other Area 1 prospects. Geological description of the Ikkari Discovery: Mineralisation at Ikkari is characterised by intense alteration and deformation. Gold is associated with fine-grained disseminated pyrite within planar quartz-carbonate veins and /or disseminated in the host rocks, commonly as fine-grained visible gold. Host rocks observed thus far include sedimentary rocks overprinted by albite-sericite alteration, and strongly foliated chlorite-altered mafic-ultramafic rocks. A broader, variably mineralised alteration zone comprising magnetite ± hematite ± tourmaline ± K-feldspar ± fuchsite is also present. Holes demonstrate strong foliation, shearing, and veining that is predominantly parallel to the dominant structural fabric and gold appears to be concentrated in sedimentary intercalations associated with zones of structural disruption at lithological boundaries, represented by irregular, cross-cutting vein associations and brittle fracture in albite-altered rocks. The regional structural data collected so far suggest a subvertical, broad and linear structure, within which cross-cutting fractures and variably dipping lithologies, as well as possibly folded bedding, appear to have controlled the introduction of gold-bearing fluids and associated alteration zones. In general, alteration and structure appear to be sub-vertical, with lithologies generally dipping 70 degrees north. Review by Qualified Person, Quality Control and Reports: Mr. Mike Sutton, P.Geo. Director and Dr Charlotte Seabrook, MAIG, RPGeo.

Samples are prepared by ALS Finland in Sodankylä and assayed in ALS laboratories in Ireland, Romania or Sweden. All samples are under watch from the drill site to the storage facility. Samples are assayed using fire assay method with aqua regia digest and analysis by AAS for gold. Over limit analysis for >10 ppm Au is conducted using fire assay and gravimetric finish for assays over >100ppm Au. For hole 120071 all mineralised samples were submitted for screen fire assays with gravimetric finish. For multi-element assays Ultra Trace Level Method by HF-HNO3-HClO4 acid digestion, HCl leach and a combination of ICP-MS and ICP-AES is used. 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 5% of the pulps and rejects are sent for check assaying at a second lab. Base of till samples are prepared in ALS Sodankylä by dry-sieving method prep-41 and assayed by fire assay with ICP-AES finish for gold. Multi-elements are assayed in ALS laboratories in either of Ireland, Romania or Sweden by aqua regia with ICP-MS finish. Rupert maintains a strict chain of custody procedure to manage the handling of all samples. The Company’s QA/QC program includes the regular insertion of blanks and standards into the sample shipments, as well as instructions for duplication.
