HUDSON REPORTS PRODUCTION OF A 55.3% NIOBIUM CONCENTRATE
FROM THE NUKITTOOQ PROJECT IN GREENLAND
Vancouver, BC – HUDSON RESOURCES INC. (“Hudson” or the “Company”) (TSX Venture Exchange
“HUD”; OTC “HUDRF”) is pleased to announce results of independent metallurgical testwork
conducted on the high-grade Nukittooq niobium-tantalum project in Greenland which is owned
100% by Hudson Resources Inc. The testwork , conducted by SGS Canada Inc. in its Lakefield,
Ontario facility , under the supervision of Hudson’s senior consulting metallurgist, John Goode,
achieved a niobium (Nb) concentrate assaying 55.3% Nb2O5 at a 66.6% global recovery along with
65% of the tantalum (Ta).
A Composite sample used in the metallurgical test program assayed 22.3% Nb2O5 and 0.3% Ta2O5.
The Composite sample was comprised of thirty-five samples collected from the Nukittooq project
in September 2020 which a veraged 19.35% Nb 2O5 over 112 meters (see NR2020 -15). The
Nukittooq deposit has some of the highest reported niobium assays in the industry.
QEMSCAN analysis indicated that the Composite sample consist ed of pyrochlore (37.3 %)
(including traces of tentatively identified columbite), aegirine (33.3%), K-feldspars (21.9%), biotite
(5.4%), and trace amounts of other minerals (ca. 2 %). The major gangue elements in the
Composite sample were 36.7% SiO2, 11.5% Fe2O3, and 4.27 % K2O. Rare earth minerals (REM)
including synchysite/parisite and bastnaesite were also present in trace amounts.
Jim Cambon, President commented: “ We are very encouraged by the success of the metal lurgical
program and the ability to produce a very high-value niobium-tantalum concentrate with recoveries
in line with or above current producers. Our goal is to define significant tonnage and rapidly
advance the project where we can ship a concentrate out of Greenland for toll processing. We will
continue to advance the metallurgical program and plan to commence a drill program in 2022 to
outline economic tonnages along the 500m strike length of this exciting target.”
The metallurgical testwork methods conducted by SGS demonstrated the following:
• Wet high-intensity magnetic separation (WHIMS)
o Conducted at 5,000 Gauss on the Composite sample ground to 80% passing 144 µm
removed 48% of the aegirine with 8.5% niobium loss. K-feldspar generally followed
pyrochlore to the non-magnetic products.
• Gravity concentration
o This showed limited effectiveness. However, the u se of WHIMS together with a
Mozley shaking table on the non -magnetic fraction showed some promise. A
combined niobium concentrate assaying 55.6% Nb2O5 at 47.6% global recovery was
produced.
• Flotation
o Seven open-circuit flotation tests were performed on stage-ground and deslimed
feed material . These tests examined a number of procedures, depressants and
collectors. SGS’s extensive experience with pyrochlore flotation allowed rapid
development of a circuit comprising WHIMS for early rejection of aegirine followed
by rougher flotation using a blend of Aero6494+F3900+Pb2+ which selectively
floated pyrochlore from K-feldspar.
o The rougher concentrate was divided into coarse and fine fractions and separate
roughing and cleaning systems , using an amine collector, applied to each stream.
The combined niobium concentrate contained 55.3% Nb 2O5 at 66.6% global
recovery.
Hudson owns 100% of the high-grade Nukittooq niobium-tantalum project and the Sarfartoq rare
earth element (“ REE”) project which are both located on the Sarfartoq exploration license in
southwestern Greenland. The Sarfartoq REE project has a 43-101 indicated and inferred resource
outlining 35,000 tonnes of neodymium oxide plus praseodymium oxide, the two key components
in permanent magnets driving the green revolution. The Nukittooq niobium-tantalum project has
some of the highest reported niobium assays in the industry with potential to extend the strike
length of this largely unexplored target. Hudson also has a 31.1% equity interest in the White
Mountain anorthosite mine and rights to acquire 100%.

information could cause actual events, results, performance, prospects and opportunities to differ materially from those expr essed or implied by
such forward-looking information. Forward looking information in this news release includes, but is not limited to, the Company’s objectives, goals
or future plans, statements, exploration results, potential mineralization, the estimation of mineral resources, exploration and mine development
plans, timing of the commencement of operations and estimates of market conditions. Factors that could cause actual results to differ materially
from such forward-looking information include, but are not limited to failure to identify mineral resources, failure to convert estimated miner al
resources to reserves, the inability to complete a feasibility study which recommends a production decision, the preliminary nature of metallurgical
test results, delays in obtaining or failures to obtain required governmental, environmental or other pro ject approvals, political risks, inability to
fulfill the duty to accommodate indigenous peoples, uncertainties relating to the availability and costs of financing needed in the future, changes
in equity markets, inflation, changes in exchange rates, fluct uations in commodity prices, delays in the development of projects, capital and
operating costs varying significantly from estimates and the other risks involved in the mineral exploration and development industry, an inability
