The Noomut Gold Project is located in Kivalliq Region, Nunavut, on the eastern shoreline of South Henik Lake, approximately 176 km northwest of Arviat and 300 km southwest of Rankin Inlet. The Noomut Property comprises two claim blocks; the Northern Block and the Southern Block. In aggregate, the two Blocks are comprised of 250 units of mineral claims covering approximately 4,819 hectares.
The mineral rights for the Noomut claims, staked in February 2021, are owned by the Crown and managed by the federal Government of Canada through the Department of Crown-Indigenous Relations and Northern Affairs Canada (“CIRNAC”). The surface rights are managed by the Kivalliq Inuit Association (“KIVIA”) requiring an access agreement to perform exploration work.
Like New Break’s other Nunavut mineral properties, the Noomut Gold Project forms part of the Henik Group, central Ennadai-Rankin Archean greenstone belt. This prolific greenstone belt is exposed in an area 700 km x 200 km forming the second largest greenstone belt in Canada, second only to the Abitibi greenstone belt in Ontario and Quebec, which has yielded over 180 million ounces of gold.
There has been little recorded exploration directly on the Northern and Southern claim blocks. Exploration has been concentrated on the known gold occurences contigous to the Northern and Southern claim blocks on the Esker gold occurrence in the north and on the Ironside and Napartok gold occurences in the south.
Esker Gold Occurence
The Esker gold occurrence is located approximately 1.5 km south of the Northern claim block, where gold mineralization is associated with quartz veins within deformed gabbro dykes and an altered granitic intrusion. In 1997, Comaplex Minerals Corp. (“Comaplex”) conducted ground geophysical surveys, geological mapping, diamond drilling and prospecting with most of the work concentrated at the Esker Main gold occurrence. A grid totaling 2.85 line-km was also established at the Esker III gold occurrence. Surface samples collected at the Esker Main occurrence included a grab sample assaying 55.5 g/t Au.
Assay results from a 7-hole, 2,026 metre 1997 drilling program on the Esker property included the following intersections (not true widths):
- 2.35 g/t Au over 70.95 metres – hole 97-13;
- 8.18 g/t Au over 13.27 metres – hole 97-15;
- 4.00 g/t Au over 5.57 metres – hole 97-16;
- 7.24 g/t Au over 5.0 metres – hole 97-23.
All of the preceding intervals were recovered from between 10 and 155 metres below surface.
Ironside and Napartok Gold Occurences
In 1996, Comaplex conducted airborne and ground geophysical surveys covering parts of the Northern and Southern claim blocks. A helicopter‐borne airborne geophysics survey consisting of magnetics and electromagnetics (“EM”) totaled 2,930.5 line‐km. Four (4) grids were laid out in 1996 which consisted of the 3 grids that made up the Napartok gold occurrence (Napartok Central, Napartok East, and Napartok West) and the Ironside grid, which was originally established in 1995. Ground geophysics was done on all four grids which entailed a Total Field Magnetic survey along with a Horizontal Loop Electromagnetic survey (“HLEM”).
In 1997 The Napartok Central grid was extended by adding an additional 19.77 line‐km. Ground geophysical surveys were only completed at the Napartok Central grid, which included a magnetics survey totaling 19.77 line‐km, a HLEM survey totaling 9.58 line‐km and an Induced Polarization survey totaling 1.6 line‐km.
During 1996, completed a diamond drilling program which consisted of 5 holes at Ironside totaling 667 metres and 7 at Napartok totaling 926 metres. Three of the holes drilled at the Ironside gold occurrence intersected anomalous gold mineralization including hole IR96‐1, which intersected 5.75 g/t Au over 3.0 metres. Of the 7 holes drilled at the Napartok gold occurrences, 4 were drilled at Napartok Central, which yielded the best intersections including 18.3 g/t Au over 3.0 metres in hole NK96‐6 and 9.2 g/t Au over 2.5 metres in hole NK96‐7. Visible gold was present in all 7 drill-holes.
In total, between 1994 and 2002, Comaplex collected over 1,500 surface samples, 692 till samples, and 1,600 core samples from 39 drill holes in the South Henik Lake area, on and in the immediate vicinity of the Esker, Ironside and Napartok gold occurences.
In August 2011, an airborne geophysical survey, consisting of 596 line-km, was flown by Fugro Airborne Surveys Corp., which encompassed parts of the Northern and Southern claim blocks. The airborne survey flight lines were orientated north‐south with a 200-metre primary line spacing and occasional 100-metre infill lines. The helicopter‐borne geophysical survey measured magnetics and EM with a DIGHEMV multi‐coil, multi‐frequency EM system. There has been no additional work completed on the Noomut Property or the contiguous claims since 2011.
Geology and Mineralization
The Noomut Property lies within the Ennadai-Rankin Archean greenstone belt, within the Hearne Province and Kaminak Subprovince, both of which are part of the Western Churchill geological province of the Canadian Shield. This prolific greenstone belt extends westward for over 700 km from Rankin Inlet.
The regional geology of the Noomut Property area comprises Henik Group rocks, which consist of middle greenschist facies metamorphosed volcanics, sediments and intrusives. The volcanics consist of intrusive and extrusive lavas along with pyroclastics, which range in composition from ultramafic to felsic. Andesites and basalts are the main compositions, while dacites, rhyolites and gabbros can be observed in minor quantities. The sediments overlie the volcanics and are mainly composed of argillites and greywackes.
The geology of the Southern Block of Noomut claims comprises sandstone and mudstone turbidites interbedded with variable proportions of felsic to intermediate tuff. There are local examples of conglomeratic units. The Ironside fault transects the Southern Block and hosts the Ironside and Napartok gold occurences on claims contigous to the Southern block.
The geology of the Northern Block of Noomut claims include the sandstone and mudstone turbidites located in the Southern Block and a chert-magnetite-silicate iron formation. The Northern Block is transected by NE trending thrust and shear faulting. The fault structures are associated with the Esker gold occurrence located on a contiguous claim approximately 1.5 km south of the Northern Block, where gold mineralization is associated with quartz veins within deformed gabbro dykes and an altered granitic intrusion.
