Green Shift Provides Metallurgical Update for the Berlin Deposit with High Recoveries
through Membrane Technology
Toronto, Ontario – November 09, 2022 – Green Shift Commodities Ltd. (TSXV: GCOM), (“Green Shift” or the
“Company”) is pleased to announce the results of further test work that show membrane technology being utilized
for testing at the Company’s Berlin Deposit to be highly efficient in separating uranium, battery commodities and
rare earth elements found in the Company’s Berlin Deposit (“Berlin”). Prior test work showed that not only could
membranes significantly reduce the size of the processing plant but could simplify the recovery of phosphoric acid
in comparison to the design modelled in the previous economic assessment of the Project completed in 2013. The
current reported results are from tests undertaken during the second phase of a three -phase testing program ,
completed earlier this year.
Highlights
• The test work was successful in achieving uranium, nickel, vanadium and rare earth element recoveries of
over 95%.
• Phosphoric acid recovery is comparatively lower and other membranes will be tested to improve its
recovery.
• The greater efficiency of membranes in separating rare earth elements could significantly increase the
potential of the Berlin Deposit.
Trumbull Fisher, Director, and CEO commented, “We are very pleased and encouraged by the improved recoveries
achieved by membranes in recovering the green energy metals during metallurgical testing on our Berlin asset.
This asset contains commodities that are critical to the global green movement as we drive towards cleaner sources
of energy and energy storage. In addition, we continue to seek other battery metal assets that would compliment
Berlin’s core commodities and be accretive to our Company’s vision of becoming a go-to source of clean energy
commodities.”
Membrane Efficiency
Test work completed to date demonstrates that membrane separation is a highly efficient process at concentrating
uranium, nickel, vanadium, rare earth elements, molybdenum and zinc from a liquid that was synthesized to match
the pregnant leach solution (“P LS”) – the liquid generated from leaching the mineralized rock - from the Berlin
Deposit. The results show that metals are effectively separated from the PLS. While phosphoric acid recovery is
not as good with the selected membranes , further work will co nsider options to improve this – aiming for a target
range of 80% to 90% recovery.

Commodity Percentage Recovery
Option A Option B
Uranium 97.1 99.7
Nickel 97.5 99.9
Vanadium 97.0 99.9
Phosphoric acid 79.3 63.6
Rare Earth Elements 98.5 99.7
Molybdenum 86.5 97.6
Zinc 96.6 99.9
Flow Rate Reduction (%) 90.2 81.2
Next Steps
• In response to the rapid adoption of lithium ferro-phosphate (“LFP”) as safe, reliable batteries by the electric
vehicle industry, it is a priority for the Company to assess the potential cost s/benefits of producing ferro-
phosphate from Berlin. It will be assessed as to whether the phosphate from Berlin can be combined with
iron to form ferro-phosphate for LFP batteries , rather than simply producing phosphoric acid as was
originally contemplated.
• The rapid advances in sensor-based sorting technology requires that this be tested on mineralized material
from Berlin. This technology uses scanners to detect physical and or chemical characteristics of mineral -
bearing components of the crushed rock as it emerges from the mine and uses a jet of compressed air to
remove the mineralized fragments from waste fragments. If this technology works on mineralized material
from Berlin, it could significantly enhance the efficiency, and could potentially lower operating costs, of a
future processing plant.
• Further work is planned to strive to improve the recovery of phosphoric acid from the 63%-70% achieved
so far to a target range of 80% to 90%.

The Company is developing the Berlin Deposit in Colombia. Apart from uranium, for clean nuclear energy, the Berlin
Deposit contains battery commodities including nickel, phosphate, and vanadium. Phosphate is a key component
of lithium-ion ferro-phosphate (“LFP”) batteries that are being used by a growing list of electric vehicle manufacturers.
Nickel is a component of various lithium-ion batteries, while vanadium is the element used in vanadium redox flow
batteries. Neodymium, one of the rare earth elements contained within the Berlin Deposit, is a key component of
powerful magnets that are used to increase the efficiency of electric motors and in generators in wind turbines.
