Multi-metal explorer Conico has detected copper sulphide mineralisation at a number of prospects explored as part of a recently completed diamond drill campaign at its Ryberg project in Greenland.
The 11-hole program was targeting copper, nickel, gold and platinum group elements at the company’s Sortekap, Miki, Cascata and Pyramid prospects that were identified from previous field campaign data.
Seven of the holes intersected zones of weakly disseminated and disseminated sulphides in mafic dykes at the Sortekap and Miki prospects.
A total of 344 samples from Sortekap and Cascata are currently at the laboratory awaiting testing with a further 345 samples from Miki, Pyramid and Sortekpa set to be shipped this week.
Conico Executive Director, Guy Le Page said: “Drill meterage at Ryberg was lower than anticipated, however we are pleased to have drilled four prospects at Ryberg this season. The presence of copper sulphide mineralisation in multiple drill holes at Sortekap and Miki is encouraging as historic surface samples at each location are known to carry PGEs.”
Six diamond drill holes were completed at the Miki prospect along a 3700m length of the target dyke with highlights including a 17.7m intercept of disseminated sulphides from 180.2.
A second hole at Miki contained a number of hits with the best result a 32.6m section of disseminated sulphides from 109.8m.
Conico says mineralisation consisted of chalcopyrite associated with bornite, pyrrhotite-pyrite and magnetite.
Drilling at the Sortekap prospect was targeting induced polarisation chargeability and magnetic anomalies previously identified from data collected over the past two years.
Significant intersections at Sortekap include a 4.2m section of disseminated sulphides from 103.6m in addition to a deeper 15.8m hit from 260.4m in the same hole.
Conico also recorded a 32.6m intercept of weak disseminated sulphides from 68.5m in a second hole drilled at the prospect.
The company says mineralisation included weakly disseminated and disseminated chalcopyrite with minor pentlandite.
A single scout hole was completed at Cascata that aims to investigate a volcano-sedimentary sequence and an interpreted layered gabbroic intrusive intersected from two holes drilled totalling 1600m last year.
A further single scout hole was drilled at the Pyramid prospect to test a magnetic anomaly identified from aeromagnetic data during the previous season.
The hole was abandoned due to poor ground conditions with no samples collected.
Conico is expecting the first assays from the latest program to completed within two weeks with drilling now over for the typically short Greenland season.
The 4521 square kilometre Ryberg tenement is in an under-explored igneous rock mineral province.
In addition to the earlier gold intersections, geochemical analysis has picked up samples rich in copper, nickel, cobalt, palladium and gold.
Conico will now be waiting to see what the lab makes of its handiwork in Greenland.
