Rupert Resources Defines Broad Copper Zones at Hein?? Central (Area 1), Extends Strike Length to 350m and Identifies Similar Mineralisation 2km East at the Island Target

2019-11-07 / @businesswire

 

Rupert Resources Ltd (“Rupert” or “the Company”) is pleased to report copper assays from initial Heinä Central drilling that show the wide sulphide-rich brecciated zones contain significant copper mineralisation along with the gold assays previously reported. In addition, assay results from hole 119050 extend the strike of mineralised zone at Heinä Central to 350m. New drilling at the “Island” target, 2km east of Heinä Central, provides evidence of another similar mineralised system.

Highlights

  • The scale of the multiple sulphide-rich breccias that host gold and copper mineralisation at Heinä Central continues to increase. Drill results over 350m of the 700m EM geophysical anomaly show strong mineralisation. Further drilling is currently underway.
  • Hole 119049 intersected two breccia zones. Copper assays from the upper zone show high grades up to 4.3% Cu associated with high grade gold zones. The lower zone which extends up to 82m includes intercepts of: 19m of 0.6% Cu & 0.7g/t Au from 125m (including 1.6% Cu & 0.3g/t Au / 3m from 126m) and 37.5m of 0.8% Cu & 0.4g/t Au from 154m (including: 1.6% Cu & 0.3g/t Au / 1m from 156m, 1.8% Cu & 0.4g/t Au / 1m from 159m, and 2.7% Cu & 0.9g/t Au / 5m from 166m)
  • New drilling at a second regional target, the “Island”, following anomalous base of till sampling over EM geophysical anomalies, has intersected similar mineralisation to the Heinä Central system. This target is 2km east of Heinä Central.

James Withall, CEO of Rupert Resources commented “The latest assay results from Heinä Central demonstrate significantly increased widths as a result of the potentially economic contribution from copper, and the ever increasing scale of the mineralising system. Our exploration program continues to deliver excellent results. The intensity of the program is now increasing with three diamond rigs active, a base of till rig testing further new targets and a detailed EM geophysical survey starting next week.”

Summary

As first reported on October 17, 2019 broad intersections of gold and copper mineralisation have been identified in a series of sulphide-rich (over 50% sulphides) brecciated zones at Heinä Central, 25km from the Pahtavaara mill (figure 1). Gold and copper correlate very well. The mineralised zones are up to 75m true width and sulphide-rich breccias intersected in hole 119050 (150m to south of previously reported drill holes) are now confirmed to be mineralised and thus extend the demonstrated strike to 350m. The electromagnetic geophysical (“EM”) anomaly associated with the main sulphide zone extends for some 700m and significant (>1g/t) gold anomalies in Base of Till “BoT” persist to the north, beyond the extent of the EM anomaly. Furthermore, reconnaissance drilling targeting a similar EM anomaly at the Island prospect, 2km east of Heinä has intersected similar sulphide breccias comprising chalcopyrite associated with pyrrhotite in quartz-carbonate veins.

New copper assays received (table 1) for holes 119047, 119049 (figure 2) and 119050 (five narrower copper zones with associated gold) indicate increased continuity of mineralisation at Heinä Central, extending the mineralised envelope.

Notes to table. True widths cannot be determined from the information available. Copper grades reported using 0.1% cut-off with max 2m internal dilution to define broad mineralised envelopes. ^Previously reported in October 17, 2019 release.

Regional exploration drilling is ongoing at other high priority targets that have been identified across the 297km2 licence holding as well as resource extension drilling at the Pahtavaara mine.

Geological interpretation

The multiple sulphide zones identified are hosted by cataclastic quartz-dolomite breccia within a sedimentary sequence that includes interbedded siltstone and carbonaceous shale and is intruded by intermediate dykes. 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 has 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 relative economic contribution at the discovery from gold and copper.
