ACN 119 057 457 AUSTRALIAN SECURITIES EXCHANGE ANNOUNCEMENT 26 July 2021 FIRST DRILL-HOLE AT RYBERG INTERSECTS SIGNIFICANT SULPHIDE MINERALISATION HIGHLIGHTS - Hole MIDD001 is the first ever drill-hole at the Ryberg Project and has been successfully completed, intersecting significant sulphide mineralisation from 78.24m to 133.12m (for a total of 54.88m) downhole. - Sulphides are present in semi-massive, matrix, vein and disseminated forms. The most abundant zone of mineralisation is between 117-124m downhole that contains approximately 4.5m of sulphide-bearing rock. - Preliminary investigations indicate that mineralisation may consist mostly of pyrrhotite and pentlandite, plus minor chalcopyrite which is a typical magmatic sulphide assemblage. - MIDD001 was collared on electromagnetic (EM) target ME1, within the Miki magmatic sulphide prospect. - Drill core will be processed and assayed as soon as possible. - The second drill-hole MIDD002 is near completion, and rigs have been established on holes MIDD003 and MIDD004, all of which are targeting magmatic sulphides at the Miki Prospect.
The drill-hole encountered a sequence of highly altered gneiss intruded by mafic rock that contains zones of intense sulphide mineralisation (figures 1,2 & 3), commencing at 117m drilled depth. In aggregate the sulphide-rich portions of the drill core cover a width of approximately 4.5m and consist of non-pyritic sulphide that is likely to be pyrrhotite and pentlandite, plus minor chalcopyrite - therefore prospective for nickel and copper. The results are preliminary in nature as no drill core has yet been sent for analysis, with results in this announcement coming from observation of the core by a suitably qualified and experienced geologist. Longland CEO Mr Thomas Abraham-James said: "I would like to start by saying thank you to the shareholders and directors of Conico for putting their faith in Longland Resources when they acquired the company last year. We are a greenfields exploration company in a location far from Australia, they saw what I did in the potential of our Greenland assets. I take tremendous satisfaction in the first ever drill-hole to occur at Ryberg encountering significant sulphide mineralisation." The Ryberg Project is located on the east coast of Greenland (Figure 4) approximately 350km NW of Iceland. Longland (a wholly owned subsidiary of Conico) is the 100% owner and operator of the licences that cover an area of 4,521km2. The current drilling program is focussed on two priority targets at Ryberg that commenced in July. The prospects are: - The Miki Prospect (Cu-Ni-Co-Pd-Au): Magmatic sulphide mineralisation associated with mafic dykes/sills that have intruded through Archean basement gneiss and Cretaceous sediments. There are well developed showings of copper-palladium-gold-rich sulphides at surface, with mineralisation occurring as globular sulphides up to ~15 cm in diameter consisting of pyrrhotite and chalcopyrite. Grab samples from surface returned up to 2.2% copper, 0.8% nickel, 3.3g/t palladium and 0.15 g/t gold. A second nickel-rich sulphide phase is also present, with surface samples grading up to 0.8% nickel and 0.1% cobalt. - The Sortekap Prospect (Au-Ni): Gold mineralisation is present at surface and is associated with quartz veins within Archean amphibolite, with surface samples grading up to 2.7 g/t Au. The mineralised veins trend ENE-WSW and appear in rusty bands in the field, caused by the oxidation of sulphides associated with the veins. Three sulphide phases have been identified which are arsenopyrite, pyrite and minor chalcopyrite. Adjacent to the gold veins is an ultramafic intrusion exhibiting magmatic sulphides with surface samples grading up to 0.33% nickel. This ASX Announcement contains preliminary results from the first hole drilled at the Miki Prospect magmatic sulphide target. There are three diamond drill rigs on site that commenced drilling on the 19th of July 2021, with the first hole MIDD001 completed on the 25th July and the second and third holes (MIDD002 & MIDD003) currently underway. All holes are targeting the Miki Prospect however one rig is scheduled to mobilise to the Sortekap Prospect later in the season.
Further mineralogical analysis is required but drill core observations indicate that sulphides are non-pyritic, most depicting varying shades of bronze colours, low hardness, slightly magnetic and are therefore compatible with pyrrhotite-pentlandite assemblages, plus minor chalcopyrite. The sulphide mineralisation which extends over 54.88m shows gradational textural characteristics with increasing sulphide content. In order starting from shallow to deep the visible sulphides consist of: - Fine veins (mm to cm scale) - Numerous commencing at 78.24m drilled depth - Sulphide matrix breccias (~30% sulphide) - 100.91-101.59m downhole - 120.66-121.41m downhole - 121.83-121.88m downhole - 132.77-133.12m downhole - Disseminated - 117.10-117.20m downhole - Semi-massive sulphide (30-50% sulphide) - 117.5-120.47m downhole - 121.41-121.83m downhole
Drill-hole MIDD001 was terminated at 217m depth in un-mineralised gneiss. The core is in the process of being cut, then sampled and sent for assay this week. Assays are anticipated to be received in 4-6 weeks, pending turnaround time at the assay laboratory. In addition to the drilling, a regional 200m line spaced heli-borne magnetic survey is underway.
