ACN 119 057 457, AUSTRALIAN SECURITIES EXCHANGE ANNOUNCEMENT, 31 August 2021
HIGHLIGHTS
- The Cascata Prospect is a new discovery interpreted to be a likely volcanogenic massive sulphide (VMS). Over 6km of strike length has been traversed, with sulphides discovered consistently at surface. The area of interest is approximately 15km^2 and is all within the Company's existing Ryberg licence. Drilling has commenced.
- SODD003 (Sortekap Prospect) is complete and intersected 78m of prospective quartz veins hosting sulphide mineralisation within amphibolite. The target is gold, with previous surface samples in the vicinity grading up to 2.7g /t gold.
- SODD002 (Sortekap Prospect) is complete and intersected 6% disseminated chalcopyrite + pyrrhotite over 7.1m from 188.5m downhole. Zones of disseminated pyrite were also encountered.
- 1 x drill rig has mobilised to an electromagnetic target at the Miki Prospect. Conico Limited (ASX: CNJ) ("Conico" or "the Company") and its wholly owned subsidiary Longland Resources Ltd ("Longland ") is pleased to announce that a new discovery interpreted as a likely volcanogenic massive sulphide (VMS) has been discovered and a drilling has commenced. SODD002 and SODD003 have been completed at Sortekap, and hole MIDD008 at the Miki Prospect.
Longland CEO Thomas Abraham-James said:
"The discovery of a potential new VMS occurrence at Cascata typifies the prospectivity of Greenland. Over 6km of strike has been traversed by foot with lithologies prospective for VMS accompanied by consistent sulphide mineralisation observed, justifying immediate drilling. Meanwhile we continue to see mineralisation in drill holes completed at Miki and Sortekap." The newly discovered Cascata Prospect Reconnaissance exploration was successful in identifying outcropping copper and iron sulphides, referred to as the Cascata Prospect (figure 1). The mineralisation is present as pyrite, chalcopyrite and bornite in massive, semi-massive, stockwork and disseminated forms, associated with black shales, rhyolitic volcanism, and underlying amphibolite (figures 2-7). Field investigations conducted thus far suggest that Cascata may potentially be a Volcanogenic Massive Sulphide (VMS) occurrence, with over 6km of strike length traversed by foot and an area of interest covering 15km^2.
Drilling has commenced at Cascata and is situated on the upper end of the stratigraphy. The prospect is situated within the existing Ryberg license and is readily accessible, located only 6km from the coast and has abundant fresh water sources.
Sortekap Prospect: Drill-hole SODD003
Drill-hole SODD003 targeted gold mineralisation hosted in amphibolite (figure 9) and was positioned to drill perpendicular to quartz veins where previous surface sampling returned grades of up to 2.7g/t gold.
The drill-hole was successful in passing through 78m of prospective quartz-bearing amphibolite, commencing at surface (figure 8). The quartz veins frequently contained trace/disseminated sulphides which is encouraging as published literature on the gold occurrences at Sortekap state that gold mineralisation is linked to the presence of trace sulphides (particularly arsenopyrite) in amphibolite. Sulphides encountered do include arsenopyrite, in conjunction with pyrite and chalcopyrite (figures 10-11).
The hole was terminated in serpentinite and the rig has since moved to the next drill-hole at the Miki Prospect, drilling an electromagnetic (EM) anomaly that was identified in the 2020 EM survey. Sortekap Prospect: Drill-hole SODD002
Located in the Sortekap Prospect, drill-hole SODD002 targeted an Induced Polarisation (IP) chargeable anomaly. The drill-hole was successful in intersecting sulphide mineralisation over multiple intervals, the most significant being 7.1m commencing at 188.5m downhole and consisting of 6% disseminated chalcopyrite and pyrrhotite. Deeper in the hole there are zones of up to 20% disseminated pyrite (figure 12).
The hole was extended in length to a total depth of 356m in order to intercept the serpentinite seen in hole SODD001. This ties the geology of the two Sortekap drill-holes together, giving a firmer understanding of the regional stratigraphy. Miki Prospect: Drill-hole MIDD008 This hole targeted magmatic sulphides associated with the Miki Fjord Macrodyke (figure 16). From 78.9m to end of hole (312m), MIDD008 intercepted a quartz - potassic feldspar - mica assemblage (figures 13 to 14) that contains veinlets of molybdenite (between 1 - 2% when encountered), and trace occurrences of chalcopyrite (2% when encountered, figure 15).
Encountering such mineralisation is unexpected, but not surprising considering the location's proximity to nearby known systems such as the Flammefjeld porphyry molybdenum project located 38km to the west.
The drill-hole was terminated at 312m drilled depth while still in the altered country rock, with the rig being re-tasked to the Cascata Prospect.
