Comments
"Our ongoing program at Risti has high ambitions; to make new discoveries and to make meaningful increases in the scale of our existing discoveries. The exploration success at Ikkari (4mm oz), by our neighbour Rupert Resources, has moved the focus of our efforts away from our outcropping discoveries hosted in clastic sediments and towards the large areas of mafic/ultra-mafic rock that lie under cover across Risti" commented Matti Talikka, Aurion's CEO. "The recently commenced scout drill program has identified gold mineralization in all selected target areas tested to date. Gold intercepts 1.5 km west of Aamurusko and at Aamurusko gabbro target expand the mineralized footprint along the Aamurusko trend. At the Kaares area, 4 km to the south of Aamurusko, drilling encountered wide zones of strongly deformed and altered mafic to ultramafic volcanic rocks with elevated gold resembling Helmi-Ikkari style of gold mineralization. In addition, a wider interval of PGE mineralization was intersected south of the Kaaresselka gold prospects further supporting the prospectivity of the untested major structure that extends for 15 km along the southern part of the Risti property."
Regional programs have generated 20 high priority targets
The vast majority of the Risti property is covered by glacial till. Such areas are not amenable to prospecting and surface mapping that has led to multiple discoveries, including the Aamurusko high-grade discovery. Base of till (BoT) sampling combined with geophysical surveys have been key exploration methods behind most gold and base metal discoveries within the Central Lapland Greenstone Belt, including Agnico Eagle's Kittila Mine, Ikkari by Rupert Resources and Sakatti by Anglo American.
The ongoing geophysical and geochemical surveys within the Risti property continue to generate numerous targets that warrant follow up work. A total of 4,134 base of till samples have been taken since late 2020 with a focus on the unexplored mafic-ultramafic domains and areas within proximity to interpreted structural features.
The surveys have generated 20 high priority targets where gold and/or pathfinder element anomalies co-exist with interpreted structural features (Figure 1). The ongoing scout drilling program is testing selected high priority targets.
Gold mineralization was intersected in 17 out of 23 holes and in all target areas tested to date (Figure 2). In addition, PGE mineralization was identified in a previously untested area.
The scout drilling program is planned to continue until mid December and will be testing further high priority targets.
Aamurusko Trend
Seven scout drill holes, totalling 1,182.00 m, were completed along the Aamurusko Trend (Figure 2). This area, located 1-2 km west of Aamurusko Main, is interpreted to be the continuation of the domain boundary hosting the Aamurusko Main gold mineralization. These holes were targeting various geophysical and geochemical features along the trend. Holes AM22215, AM22216 and AM22217 were drilled along the same profile approximately 1.5 km west of Aamurusko Main. Holes AM22215 and AM22217 intersected 2.17 g/t Au over 2.90 m from 152.35 m and 0.60 g/t Au over 1.25 m from 93.20 m, respectively. This mineralization is hosted by siliciclastic sediments proximal to the domain boundary. Holes AM22218, AM22219 and AM22220 were drilled along the same profile approximately 2 km west of Aamurusko Main. Holes AM22218 and AM22219 intersected anomalous (>0.1 g/t Au) values up to 0.24 g/t Au. This mineralization is also hosted by siliciclastic sediments proximal to the domain boundary.
Two scout drill holes, totalling 200.60 m, located 2 km west-northwest of Aamurusko Main, were drilled to test a BoT anomaly. Hole AM22221 was abandoned and re-collared as AM22222, which intersected 0.11 g/t Au over 0.85 m from 57.15 m within siliciclastic sediments.
The gold intercepts in these widely spaced scout holes confirm that the interpreted domain boundary, that remains mainly untested for 5 km to the west from Aamurusko Main, is prospective for the existence of gold mineralization.
Aamurusko
In the Aamurusko Main and Aamurusko NW areas, four drill holes were completed for a total of 1,781.40 m. The holes were planned to test for mineralization within the gabbro units adjacent to the domain boundary (Figure 3). All four holes successfully intersected gold bearing structural zones within gabbro and sediments proximal to a domain boundary. At Aamurusko Main, hole AM22210 intersected multiple mineralized intervals including 1.74 g/t Au over 2.85 m from 259.45 m, 5.57 g/t Au over 1.00 m from 281.85 m, 1.27 g/t Au over 2.50 m from 305.50 m and 1.26 g/t Au over 2.05 m from 394.35 m. At Aamurusko NW, hole AM22212 intersected 0.25 g/t Au over 49.60 m from 278.40 m. These intersections provide further indications of the potential to host gold mineralization of scale in mafic and/or sedimentary rocks.
Notches
A total of five drill holes, totalling 434.70 m, were completed in the Notches area (Figure 2). These holes were targeting a mineralized conglomerate unit exposed in Aurion trench NOT1817. All five holes intersected gold mineralized intervals within the conglomerate unit over a strike length of 150 m. Mineralization was also intersected in the host sandstone unit. Mineralized intersections include: 7.03 g/t Au over 0.90 m from 50.25 m, 1.19 g/t Au over 0.87 m from 59.63 m and 1.41 g/t Au over 1.35 m from 62.15 m in hole AM21205; 5.38 g/t Au over 1.15 m from 46.40 m and 1.03 g/t Au over 1.35 m from 68.10 m in hole AM22209; 2.27 g/t Au over 1.00 m from 54.15 m in hole AM22206.
The gold mineralization intersected extends the structures and confirms the style of mineralization observed in the trench NOT1817 area. The drill holes focused on a small area within the 5 km by 1 km Notches prospect from which approx. 2,650 grab samples averaging 2.2 g/t Au have been collected.
Kaares Area
Six scout drill holes, totalling 869.40 m, were completed in the greater Kaares area in the southern part of the Risti property (Figure 4). The scout holes targeted selected geophysical and geochemical anomalies located on or adjacent to interpreted domain boundaries outside previously drill tested areas. The anomalies resulted from Aurion's ongoing BOT sampling and geophysical surveys.
Drilling intersected new gold bearing zones in highly deformed and altered mafic volcanic rocks in previously untested areas. KS22016 and KS22017, located approximately 1.7 km SW of Kaaresselka, returned 3.07 g/t Au over 1.00 m from 34.90 m and 1.66 g/t Au over 1.22 m from 41.00 m respectively. In addition, a wider zone of anomalous gold, up to 0.28 g/t, was intersected (KS22019) approximately 1.4 km NW of Kaaresselka.
Drill hole KS22015, located 1.7 km SW of Kaaresselka, intersected mafic intrusive hosted Pt and Pd mineralization, returning an interval of 0.30 g/t Pt+Pd over 43.10 m from 74.50 m. This new mineralization, along with a previous interval of 1.43 g/t Pd, 0.51% Cu over 0.85 m from 71.80 m in hole KS21014 (2.5 km E of KS22015), highlights the Pt and Pd potential of the area.
The existence of gold mineralized zones in strongly altered and sheared mafic volcanic rocks well outside the previously drill tested areas and the large number of untested geochemical and geophysical anomalies further support the prospectivity of this major structural trend that extends 15 km in the southern part of the Risti Property.
