Rupert Resources Reports New Drilling at Heinä Central Identifying High Grade Near-Surface Mineralisation
Rupert Resources’ (“Rupert” or “the Company”) on-going systematic drilling campaign has confirmed a second parallel zone of mineralisation at the Heinä Central discovery in Area 1, 25km from the Pahtavaara mill.

Highlights
- Hole 119062 intersected a mineralised zone of 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) confirming a second higher grade mineralised zone, parallel to the main zone of mineralisation at Heinä Central
- Heinä Central continues to grow. Drilling has now intersected similar sulphide-rich breccias over a strike length of 600m of the 700m EM anomaly. The recently completed down-hole EM survey has also indicated depth potential to at least 350m
James Withall, CEO of Rupert Resources commented “These latest higher grade assay results, near to surface, and in a second zone at Heinä Central further demonstrate the potential for economic continuity of mineralisation. The results show the ongoing effectiveness of Rupert’s exploration approach to generate positive drill results across its 297km2 land package in the Central Lapland Greenstone Belt.”
Summary
As previously reported on November 7, 2019 a broad zone of gold and copper bearing sulphide mineralisation has been identified at Heinä Central, in Area 1 of the Pahtavaara Project (figure 1). Previously reported shallow intercepts from hole 119049 of 4.1g/t Au & 1.6% Cu over 4.0m from 35m (including 12.7 g/t Au and 4.3% Cu over 1.3m) and 8.3g/t Au & 2.0% Cu over 1m from 44m indicated a second zone to the east of, and parallel to, the broader main zone of mineralisation. The follow-up drilling in hole 119062 was designed to test the potential for vertical extent and successfully identified a more cohesive zone of mineralisation grading 3.3g/t Au and 1.5% Cu over 10.6m from 84m. This hole has confirmed continuity to at least 75m vertical depth with high-grade gold and copper mineralisation.
So far three mineralised zones have been identified within the broader envelope and mineralisation is open to the north, where untested base of till anomalies (>1g/t Au) are present, and to the south east. Estimated true width of the broadest zone intersected to date is up to 75m. Drilling has intersected sulphide-rich breccias over strike length of 600m with results received to date from drilling over 350m. Recently completed down-hole EM surveys from three holes indicate multiple sulphide zones that extend to at least 350m vertical depth. Drilling will continue to test the strike and depth potential of this discovery.

Ongoing Programs
The success of the first three months of the Company’s exploration campaign has been outstanding. At the end of November 2019 a total of 5,072m had been drilled of our planned 15,000m regional exploration program and assays remain pending for initial drilling at the Hirvi and Island projects. Further to this, the base of till sampling over geophysical targets continues to identify further coincident anomalies of interest. Drilling will continue throughout the winter.
At the Pahtavaara mine, the Phase one surface diamond drilling program that has demonstrated an exceptional hit rate, will be completed in the coming weeks. The Phase Two program comprising surface reverse circulation and underground diamond drilling will begin in January.
Geological interpretation
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 regional thrusting and localised folding. The extent and orientation of these structural zones and of the multiple mineralised zones, have not yet been fully determined and sulphide mineralisation remains open in all directions. Mineralised intercepts indicate that sulphides host broad zones of gold and copper mineralisation, with the potential for higher grade shoots to be developed within. Multi-element data and mineralogy suggests a magmatic component to mineralising fluids and the development of redox gradients, particularly evident by pyrite to pyrrhotite transitions, contributing to gold precipitation. Rupert has commenced metallurgical studies to understand the potential recoverability of gold and copper at this discovery.
