MAWSON EXPLORING 9 HIGH GRADE BOULDER FIELDS OVER 12 SQ. KM IN FINLAND
160 boulders with gold grades ranging from 0.1 g/t gold to 3,870 g/t gold, with an average of 74.9 g/t gold and
median of 0.71 g/t gold
Vancouver, Canada – Mawson Resources Limited (“Maws on”) or (the “Company”) (TSX: MAW) (Frankfurt:
MXR) (PINKSHEETS: MWSNF) announces the result of a systematic review of nine prospect areas at the 100% owned
Rajapalot gold project in Finland. These prospect areas we re discovered by the Mawson team as gold-bearing boulder
fields, from which 160 gold mineralized boulders have now been identified within a 12 square kilometre area. The potential
bedrock source of only three of the nine boulder fields have been located by drilling, with the remaining six boulder trains
now planned for follow up exploration.
Key Points:
A total of 160 boulders and outcrops with >0.1 g/t gold have been discovered within a 4 kilometre by 3 kilometre
area at Rajapalot. Gold grades range from 0.1 g/t gold to 3,870 g/t gold, with an average of 74.9 g/t
gold and median of 0.71 g/t gold. Samples from boulders are grab samples, which are selective by nature and
are unlikely to represent average grades on the property;
The sources of six of nine gold bearing boulder fields remain to be discovered;
The sources of three have been discovered by drilling over the last 18 months, these being:
Palokas (including 10.0 metres @ 11.6 g/t gold from 110.2 metres, Mawson Release Feb 21, 2017)
Raja (including 27.0 metres @ 3.3 g/t gold from 64.0 metres, Mawson Release May 02, 2017),
South Palokas (including 8.4 metres @ 4.2 g/t gold from 206.0 metres, Mawson Release March 07, 2016)
Glacial transport direction, combined with geological features and base of till drill results indicate only a short travel
distance for all mineralized boulders (<250 m). Rock outcrops related to the boulders have been discovered in five
of the boulder fields.
Discoveries of additional Palokas-style amphibole-tourma line-chlorite-pyrrhotite boulders over the last month
(assays pending for 4 mineralized boulders) at Hirvimaa have defined immediate drill targets in areas that can be
drilled year-round;
Winter drilling (2017-18) will focus on delineation of additi onal gold mineralization in prospects already identified
by drilling, and follow-up of boulder fields where the primary source of mineralization remains to be discovered.
Mr Hudson, Chairman & CEO states, "With more than 99% of the gold prospective area at Rajapalot covered with a thin
layer of glacial soil, tracing the source of boulders remains a key to further discoveries. The frequency of boulder discovery
at Rajapalot over at least 12 sq km is impressive. Our field teams are regularly making new finds, including the exciting
Palokas-style mineralized boulders at Hirvimaa, that present immediate drill targets. The bedrock source of only three of
nine boulder fields are known to date, with all nine still providing excellent discovery opportunities.
Further discoveries at Rajapalot will come through rigorous exploration practices and a commitment to drilling. Given the
high success rate of drilling during the last winter program where 28% of drill holes (39 out of a total of 137) recorded
greater than 5 g/t-m intersections, we are looking forward to our upcoming programs.”
A summary of sample statistics is shown in Table 1 and description of all boulder fields is shown in Table 2. Samples from
boulders are grab samples, which are selective by nature and are unlikely to represent average grades on the property. A
lower cut-off for reporting of the boulders is 0.1 g/t Au, and the range, mean and median are all reported to give a more
accurate representation of sample variation.
Compilation and re-examination of all the boulder information was conducted for comparison of the drill results of the 2016-
17 winter drilling and base of till (BOT) results with previously held data. The geochemistry, mineral assemblages and the
shape and size of all boulders was reviewed. Company geologists have determined that the grade distribution of boulders
and their spacial association with outcrops and drill results in dicate that the shallowly buried sources are close to the
northwestern edges of the defined boulder fields.
The source of three boulder fields identified in Figure 1 (Pal okas, South Palokas and Raja) have been located. The source
of the largest boulder field, Rumajärvi, remains elusive, bu t as the boulders contain highly anomalous and disseminated
gold with pyrrhotite, this remains a hi gh-priority target for 2017-18 winter drill pr ogram. Geophysical studies, including
distinguishing magnetic pyrrhotite-bearing metasediments from magnetic volcanic rocks is allowing more effective targeting
of boulder sources.
Technical Background
The qualified person for Mawson's Finnish projects, Dr. Nick Cook, President for Mawson and Fellow of the Australasian Institute of Mining
Metallurgy has reviewed and verified the contents of this release.
Boulder samples were assayed between 2012-2015 and transported by Maws on personnel from site to AL S Chemex Ltd's laboratory in
Pitea, Sweden where the samples were prepared and sent to ALS Chemex Ltd's laboratory in Vancouver, Canada to be analyzed by Au-
ICP21, GRA-21, ME-MS41u and ME-MS61u techniques. The QA/QC program of Mawson consisted of the systematic insertion of certified
standards of known gold content, with blanks at the beginning of each batch. In addition, ALS Chemex inserted a number of blanks and
standards into the analytical process.

found boulder targets; 4 of
these drill holes were not
focused on Palokas-style

Boardwalk
Two types of large boulders
present: grunerite-chlorite-
pyrrhotite-magnetite boulders
with <5 g/t Au and micaceous
sulphidic boulders (up to 221
g/t Au)
Both types of boulders are
magnetic and sulphidic so can
be tested with a combination
of ground magnetics and
gradient array IP.
Magnetic ironstones have been
intersected in early drilling, but
the sulphidic and gold-bearing
rocks are yet to be found.
Micaceous sulphidic rocks are
similar to those found at South
Palokas, and may be derived
from there (< 200 m)
NO 4 NQ drill holes have not
intersected target
Ground magnetics at <50
m spaced lines will be
conducted before further
drilling.
Terry’s
Hammer
22 anomalous boulders spread
across nearly 400 metres;
boulders are large and angular
(many 50 cm to 1 m
diameter). They are inferred to
be derived from the NW and W
edges of the boulder field.
This boulder field and
Rumajärvi (below) are
characterized by micaceous,
sulphidic and magnetic
boulders. As such, they form
excellent combined magnetic
and IP targets.
Narrow intersections in
outcrops do not appear
representative of boulders; the
4 NQ drillholes within and
adjacent to the boulder field
have not intersected the
source
NO Limited drilling has not
located source yet
Drill testing in areas
adjacent to early 2017
drill holes. Additional
magnetic data indicates
more targets to west and
northwest of existing
drilling
Rumajarvi
The best-developed boulder
field in Rajapalot with 55
boulders sampled over 0.1 g/t
Au; highly variable in size and
shape, with some over 2 m in
diameter. Many are angular
indicating close to source.
Magnetic, sulphidic boulders
form the bulk of the
mineralized boulders. More
detailed ground magnetics
(<50 m line spacing) will be
used in follow-up
A few outcrops within the
boulder field are identified, but
only in the central and SE
parts. Therefore, the up-ice
source has not yet been
located.
NO
A single drill hole (PAL0037)
intersected some gold
mineralization, but not of
the major boulder type.
PAL0037: 56 m @ 0.53 g/t
