Sweden
European GIGAFACTORIES
Summary
The Bergby Project is a newly discovered Lithium deposit in central Sweden, near to the world famous Woxna graphite mine, the new Northvolt lithium battery gigafactory, and close to major mining and transportation infrastructure, workforce and equipment.
The Bergby project is secured by eight exploration licenses that cover a total of 10,828 Ha.
Bergby is optimally positioned to benefit from access
to the EU/UK market and the demands for alternative energy vehicle manufacturing, high tech devices and grid storage systems, proximity to next generation Lithium-Ion battery manufacturing plants, educational institutions and the development of Li-Ion research and development as well as an abundant supply of fresh water and low power costs for processing hard rock lithium bearing minerals cost effectively.
The property is prospective for near-surface lithium mineralization observed in surface boulders and outcrops, positioning the property for cost effective extraction potential.

PROJECT TENURE
Historic Work
Mapping and sampling of the Bergby site located an extensive lithium-mineralized surface boulder field. Assay results from 41 boulders shows Li2O (lithium oxide) averaged 1.06% and ranged from 0.03% to 4.56%; and Ta2O5 (tantalum pentoxide) averaged 168ppm and ranged from 1 ppm to 499 ppm.
The Discovery
Further mapping located lithium mineralization in outcrop, as reported during December 2016. Fifteen samples from three outcrop areas returned Li2O averaging 1.71% and ranging from 0.01% to 4.65%; and Ta2O5 (tantalum pentoxide) averaging 133 ppm and ranging from 16 ppm to 803 ppm.
Samples included representative chip samples, composite samples and selective grab samples depending on outcrop quality and were taken from three sites across an area of approximately 350m x 750m.
In 2017, the first drill program was completed on the project. 28 of the 33 holes drilled on the property intersected lithium mineralization along an approximate 450m strike length. The deepest holes tested approximately 65m below surface with mineralization open along strike in both directions and well as down dip.

MINERALIZATION
Three principal styles of lithium mineralization have been observed in boulders and outcrops, providing encouragement that mineralization may be extensively developed.
- Homogeneous, fine grained to medium grained leucogranite/aplite: Complex zoned boulders where the aplite textured material appears to intrude coarse grained pegmatite observed. This style is rich in tantalum, with an average grade from 31 boulders of 208 ppm Ta2O5. The lithium mineralogy of this style not yet confirmed; however, the low measured specific gravity of highest-grade samples suggests petalite is dominant.
- Petalite dominated extremely coarse-grained pegmatite: Located in both outcrop and boulders, this style is relatively poor in tantalum and high in lithium.
- Spodumene bearing very coarse grained pegmatite: Coarse grained spodumene crystals have been recognised in boulders, with crystals up to 30 cm in length.
GROUND MAGNETIC SURVEY
A low magnetic feature is present where later drilling identified the thickest part of the pegmatite
IMAGE A is showing the drilled thickness (close to true width) of the pegmatite. Blue crosses on the drill holes is showing the intersection point projected to surface. IMAGE B is showing countours of the thickness times the composite Li2O grade (Li2O x m) of the same intersections.
