Conico has logged zinc, lead and copper sulphides from a 10-hole diamond drill campaign at its Mestersvig project in Greenland consistent with the historic Blyklippen zinc-lead mine at the site.
Eight of the 10 holes completed intercepted disseminated, heavily disseminated or matrix sulphides during the program that was testing for extensions to the known mineralised vein system identified at the Blyklippen and Sortebjerg prospects about 13km along strike from one another.
The explorer says holes that intercepted the modelled mineralised vein exhibit similar mineralisation to the historic Blyklippen mine.
Visual analysis of the drilling returned results including 3.3m of disseminated sulphides from 205m and 15.5m of disseminated sulphides from 211.5m in a second hole.
The company also highlighted a 4.5m hit of matrix sulphides from 134.1m and a 1.4m intercept of heavily disseminated sulphides from 120.5m in a fourth hole.
Conico says it will test assays for zinc, copper, lead and silver with results expected within six to eight weeks.
Reconnaissance exploration has also identified additional lead mineralisation hosted in veins near the surface at the company’s Nuldal prospect.
Conico says it has discovered a massive galena outcrop up to one metre thick that runs roughly parallel to the Blyklippen prospect.
Two rock chip samples taken from the area in 2020 returned results of 60.66 per cent lead, 0.91 per cent copper and 236 grams per tonne silver whilst the second sample recorded 69.47 per cent lead, 0.77 per cent copper and 282 g/t silver.
Conico Executive Director, Guy Le Page said: “Mineralisation at Mestersvig is readily identifiable via visual investigation, with most holes penetrating the anticipated vein system that is known to contain zinc, lead, copper and silver mineralisation. It is pleasing to see that the mineralised vein continues along strike, proving our modelling to be correct and we await the assay results with anticipation.”
The historic Blyklippen mine produced a total 545,000 tonnes of ore at 9.3 per cent lead and 9.9 per cent zinc between 1956 and 1962 and is on the east coast of Greenland, 5km from the Mestersvig military base.
Previous surface grab sampling at Mestersvig returned results of 7.0 per cent copper, more than 10 per cent lead, 0.8 per cent zinc and 273 g/t silver.
Conico has two large wholly owned projects on the east coast of Greenland and previous exploration has been limited.
Last week the multi-metal explorer detected copper sulphide mineralisation at a number of prospects explored as part of a recently completed diamond drill campaign at its nearby Ryberg project.
The 11-hole program at Ryberg 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.
With both drill campaigns at Greenland wrapped up for the year, Conico will be eager to see what the laboratory can discover from the latest assays.
