Sienna Resources Employs Norway’s Arctic Drilling AS for its Slättberg Project

Sienna Resources Inc. reports that it has employed Norway’s Arctic Drilling AS as the driller on the scheduled multihole drill program on its flagship platinum-palladium and nickel Slättberg project located in Sweden.

We are very pleased to have Arctic as our drillers. They have a vast knowledge of the area which is a tremendous asset. We are planning on building on our success from the last drill program which intersected some of the highest PGE numbers to date on the property (4.15 g/t) PGE.

Jason Gigliotti, President, Sienna Resources Inc.

Gigliotti continued, “We are expecting to commence drilling shortly at a time when the junior mining market is showing robust fundamentals. We are very optimistic about what this drill program will uncover at a time when the market is much more receptive to drill results than when we drilled last year.”

In October 2019, Sienna performed a two-hole drill program at the Slättberg project located in southern Sweden. The target of that program was two electromagnetic (EM) anomalies identified by downhole surveys conducted at the end of the 2018 drill program.

One anomaly was identified in and around the SIE-18-006 drill hole, which is situated at the west end of the trend of historic nickel mines. The other anomaly was identified close to the SIE-18-003 drill hole, in the vicinity of the center of the mineralization trend.

The SIE-19-002 drill hole was drilled to investigate a powerful EM response to the west of the SIE-18-003 drill hole at the center of the mineralization trend. The SIE-19-002 drill hole intersected a PGE-rich vein with a width of 0.55 m (from 88.0 m to 88.55 m), averaging 1.79% Cu, 0.22% Ni, and 4.15 ppm (4.15 g/t) PGE (4.05 g/t Pt versus 0.095 g/t Pd).

In this vein, there is a prominent peculiar enrichment of PGE, which represents one of the maximum values ever reported from the property. PGE contents observed in the 2019 drill holes of Sienna show powerful PGE potential on the project.

In the SIE-19-002 drill hole, unmapped mine workings were intercepted at a depth of 70 m. This shows that nickel mineralization was extensively mined than suggested by historic records.

The SIE-19-001 drill hole was drilled to investigate the western anomaly. Multiple sulfide mineralization zones were intercepted in this hole over an interval of 28 m at depths of 167 to 195 m. This represents the widest sulfide mineralization zone ever intercepted on the property.

Sulfide mineralization was found as huge sulfide veins and in breccias. It is also associated with an extremely thick swarm of mafic dikes. The highest intercept from within the sulfide mineralization zone was 5.0 m (from 167.75 to 172.75 m), averaging 0.06% Co, 0.47% Cu, 0.57% Ni, and 0.48 ppm PGE (actual thickness predicted to be 55%–65% of reported interval), or about 1% Ni equivalent.

Textures in the sulfide intervals indicate tectonic sulfide remobilization from an adjacent source. Several thick mafic dikes were also found in SIE-19-001. These dikes were not observed in surface exposures or in the shallow drill holes in other parts of this area.

The higher PGE values, sulfide abundance, and multiple mafic dikes indicate that Sienna is turning out to be a source area for the sulfide mineralization and related mafic intrusions, with drilling performed to increasingly deeper levels in the western target area.
