AAMURUSKO PROSPECT

Aamurusko Prospect

The Aamurusko prospect is located near the center of the Risti Property. A total of 1,210 samples with an average grade of 24.9 g/t Au have been collected from an area measuring 1.7 km by 1.3 km. The samples are predominantly from large and angular quartz (with or without tourmaline and/or Fe-Oxide) blocks with many samples containing coarse visible gold. The quartz vein blocks range from 0.1 m to >3 m wide, trend NE-SW and are hosted by quartzites and polymictic conglomerates of the Kumpu Group and mafic volcanics of the Sodankylä Group. The conglomerates are interpreted to be unconformably in contact with the mafic volcanics.

The initial prospecting and mapping campaign was followed by further field activities including the maiden drilling program in 2017 and follow up drilling programs in 2018, 2019 and early 2020. A total of 138 holes and 24,216 m of drilling has been completed in the Aamurusko area at various targets including Main, NW and Gap Zone.

At Aamurusko Main, gold mineralization intersected at shallow depths (40-60 m vertically from surface) expands known mineralization in an area that is now estimated to be 100 m long in an east-west orientation with a sub-vertical distance of 150 m. Multiple high-grade (anything greater than 10 g/t Au is considered high-grade) intercepts occur in this area including a very high-grade intercept of 789 g/t Au over 2.90 m.

While true widths are unknown at this time, the ability to successfully target and intercept gold mineralization with drill step outs both vertically and horizontally suggests that the mineralization appears to form part of a coherent body or shoot. The mineralization lies proximal to the faulted/sheared contact between a gabbro intrusive and sedimentary rocks. Mineralization remains open at depth and along strike.

Drilling at Aamurusko Main has been focused over an east-west distance of approximately 250 m at the eastern extent of the boulder field. This suggests that the mineralization encountered there is only one source of the many high-grade boulders at Aamurusko. Gold mineralization was also intersected in 500 and 800 m step out drill holes to the west-northwest providing further evidence that additional near surface gold mineralization may exist in the same geological/structural setting west of the current main focus of drilling.

Drilling 235 m east of Aamurusko Main also returned significant drill intercepts:

Aamurusko NW is approximately 600 m northwest of Aamurusko Main target. This target consists of a 10- 30 m wide zone of gold-bearing quartz veins within altered and mineralized clastic sedimentary rocks. Drilling has delineated Aamurusko NW to 300 m vertical depth and the mineralization is open to extensions. Drilling in early 2020 also identified new zones of gold mineralization 200 m north of Aamurusko NW along and on the northern side of a previously untested fault structure.

Aamurusko Gap covers the approximately 600 m long “gap” between the Aamurusko NW and Aamurusko Main targets. Mapping has identified fault structures and a widespread quartz stockwork extending 300 m by 100 m. The target was tested by a few drill holes in early 2020. All drill holes intersected zones of gold mineralization.
