The first prize of Ujarassiorit 2019, 55,000 Danish kroner (tax-free), goes to Louise Therkildsen from Ikerasak, south of Uummannaq. The winning rock sample is a sulphide-bearing hydro-thermal vein in a volcanic rock from the Angineq island, 10 km southeast of the Svarthenhuk Peninsula. The in-situ sample contains 0.1 g/t gold, 389 g/t arsenic, 10 g/t thallium, 113 g/t molybdenum and 0.1 g/t rhenium. The gold, arsenic and thallium metals indicate a potential hydrothermal gold mineralisation in the area.
The second prize of Ujarassiorit 2019, 25,000 Danish kroner (tax-free), goes to Therkild Hansen from Qaarsut on the Nuussuaq Peninsula for his nickel-bearing basaltic rock sample. The sample yields over 1% nickel, 0.25% copper, 0.2 g/t palladium, 0.1 g/t platinum and has slightly elevated gold content. While the Nuussuaq Peninsula has known nickel and copper potential, this sample indicates a potential new area for nickel and copper mineralisations southwest of Qaarsut. Nickel is mainly used for producing stainless steel, but is also a main component in metal alloys used in high-tech products, such as medical equipment, electronics and energy generation devices.
The third prize of 10,000 Danish kroner (tax-free) each goes to two winners:
- Laura Jensen from Narsaq, for her sulphide-bearing granitic rock sample found in Kangerlua, 16 km northwest of Narsaq. The sample yields 0.84% zinc and 0.22 % lead. Similar zinc-lead mineralisation has been previously documented through Ujarassiorit, but this sample shows the possibility of finding this type of mineralisation over larger areas.
- Otto Ugpernangitsoq from Attu, for his iron-, niobium-, and rare earths-bearing hydrothermal rock sample. The sample yields 41.7% iron, over 500 g/t niobium, 672 g/t lanthanum and over 500 g/t cerium.
The fourth prize of 5,000 Danish kroner (tax-free) each goes to four winners:
- Ludvig Knudsen from Kangersuatsiaq for his in-situ rusty, sulphide-bearing gneiss sample from Singarnaq island, 25 km south of Upernavik. The sample is rich in iron-sulphides (yields 29.1% iron), and contains several other metals in slightly elevated amounts – 0.1 g/t gold, over 500 g/t cerium, and 490 g/t lanthanum.
- Aninaaq Kivioq from Qaanaaq, for her magnetite-rich sample. The sample is likely an intrusive rock yielding over 50% iron, 0.17% copper and 268 g/t tin. The combination of iron, copper and tin is quite rare in Greenland.
- Kristian-Henrik Hansen from Nuuk, for his sulphide-bearing gneiss from Iterlak, on southern shore of Ameralik Fjord south of Nuuk. The sample is rich in iron sulphides, pyrrhotite, and yields 17% iron, 0.61 % zinc and 0.12 % copper. A few minor occurrences of these base metals are found in the Nuuk-region, mainly north of Ameralik Fjord.
- Aviaaja Olsen from Nuuk, for her rock sample with the green gemstone, greenlandite. The sample was found in Oqummiaa, along the northern part of the west coast of Nordlandet. The sample location is not primarily known for this mineral, but has general gemstone potential.
1100 rock samples were submitted to Ujarassiorit in 2019. 169 of these samples showed signs of mineralisations, and were sent for geochemical analysis.
The jury committee of the country-wide mineral hunt, Ujarassiorit, consisted of ore geologists from the Ministry of Mineral Resources, and the Geological Survey of Denmark and Greenland (GEUS). Ujarassiorit is only for Greenlandic residents, who can participate by sending in samples for free from every post office in Greenland to the Ministry for geological inspection. Further information on the Mineral Hunt can be found www.ujarassiorit.gl.
Ujarassiorit is organised and financed by the Ministry of Mineral Resources. The prizes are sponsored by the following funds and companies:
The Bank of Greenland contributed with 40,000 Danish kroner.
Greenland Resources Inc. and Greenfields Exploration Ltd. each contributed with 10,000 Danish kroner.
Naalakkersuisut (The Government of Greenland) congratulate all the prize winners and thank all participants of Ujarassiorit 2019 for getting involved in promoting the mineral resource sector in Greenland. Merry Christmas and Happy New Year.
