Minviro, UK has carried out an independent Life Cycle Assessment ("LCA") of the
rutile product to be produced at Engebø Rutile and Garnet. The assessment shows
that rutile from Engebø is top rated in terms of carbon footprint compared to
alternative sources globally and has a superior water scarcity impact.
Results from the LCA
The LCA is a cradle-to-gate assessment of the production of natural rutile
concentrate from Engebø and covers all production stages from the mine to the
final product. The study includes calculations of the Global Warming Potential
("GWP") and the water scarcity footprint. The GWP covers scope 1, 2 and 3[1]
calculations of Green House Gas ("GHG") emissions. The water scarcity footprint
is based on water consumption and the regional water scarcity using the AWARE[2]
methodology.
The table below presents the results summary of the LCA of the rutile product
from the Engebø Rutile and Garnet operation.
Impact Category Impact Value Units (per kg rutileconcentrate)
Global Warming Potential 0.17 kg CO? eq.
Water Scarcity Footprint 0.03 kg water eq.
Logistical advantages, minimal internal transportation and availability of green
hydroelectric power gives a beneficial GWP for the Engebø rutile. The main
drivers of the GWP are the consumption of diesel in the mining operation and the
explosive consumption related to the ore extraction.

Process water at Engebø will be sourced and converted from saltwater resulting
in a limited water impact form the operation. The water impact is primarily from
the impact of consumption of materials such as explosives (specifically ANFO -
ammonium nitrate fuel oil), grinding media, and diesel.
Benchmarking against other raw materials
Minviro conducted a benchmarking study to compare the rutile from Engebø with a
wide range of titanium-bearing feedstock production routes, including other
natural rutile products, synthetic rutile, and titanium slag. The analysis shows
that the GWP and water scarcity impact of the Engebø rutile is top rated and
substantially lower than several alternative sources. Result from the GWP
benchmarking is summarized in the graph below.

Natural rutile (~95% TiO2) is known as a superior titanium feedstock due to its
high purity and TiO2 content. Other alternative titanium feedstocks such as
ilmenite has a substantially lower TiO2 content (~50% TiO2). Natural rutile can
be used directly in chlorination plants to make titanium pigment or as feed for
titanium metal production, while the other raw materials have to go through
additional processing steps. Ilmenite must be converted to upgraded synthetic
rutile or titanium slag. This is done through carbon intensive leaching or
smelting processes that produces substantial amounts of waste. The favorable
logistics combined with the purity of the rutile product gives the Engebø rutile
environmental benefits as a raw material.
"The LCA gives valuable insight into environmental advantages of sourcing rutile
form Engebø. The Engebø rutile will form a good basis for low carbon titanium
value chains. The study also tells us where we should put our effort to do
better. We will continue the work to minimize our environmental footprint and
aim for zero carbon emissions. We are in the process of looking at options to
phasing out diesel in the mine", says VP Resources and Sustainability, Mona
Schanche.

Nordic Mining ASA (www.nordicmining.com)
Nordic Mining ASA ("Nordic Mining" or the "Company") is a resource company with
focus on high-end industrial minerals and metals. The Company's project
portfolio is of high international standard and holds significant economic
potential. The Company's assets are in the Nordic region.
Nordic Mining is undertaking a large-scale project development at Engebø on the
west coast of Norway where the Company has rights and permits to a substantial
eclogite deposit with rutile and garnet. Nordic Mining also holds 12.0% of the
shares in Keliber Oy, which is developing a lithium project in Finland to become
the first European producer of battery grade lithium hydroxide.
In addition, Nordic Mining holds interests in other initiatives at various
stages of development. This includes patented rights for a new technology for
production of alumina and exploration of seabed minerals.
Nordic Mining is listed on Euronext Expand Oslo with ticker symbol "NOM".
