TRENCHING AND PRELIMINARY BENCH TESTING
RETURNS HIGH GRADE GOLD SAMPLES
ON THE
GOLDSMITH PROPERTY
January 15, 201 9, Vancouver, BC – Black Tusk Resources Inc. (“Black Tusk” or the
“Company) (C:TUSK) is very pleased to announce preliminary results for all samples
taken during the 2018 trenching and sampling program on the Goldsmith Property.
Initial results from bench scale testing - Bulk Gravity Assay ( BGA) – has provided
preliminary information in regards to gold grain size and potential grade of the sample
sites selected along the zone of interest.
The calculated grade returned from the preliminary testing include 14.42 grams per
tonne (g/T) gold from the ASP #1 vein, and 5.34 g/T gold from the Black Vein #1, with
5.26 g/T gold from HAM #2. Gravity recoverable gold was considered very high in
some sa mples, ranging up to 85.9% (HAM #2), and averaging 63.1% for all samples
(Note: HAM #1 and HAM#2 results were previously summarized in preceding Black Tusk
news release).
Preliminary Table of Results – Met-Solve BGA process
Black Tusk designed the fall 2018 sampling program to better characterize the “ nugget
gold” effect that appears to be common within the historic mine trend, by obtaining
larger volumes of samples from each trench site. Twenty -litre buckets were filled with
sample material representing the mineralized body, and in places, the enveloping wall
rock was also sampled. Each bucket weighed in the range of 20 to 30 kilograms when
filled with sample material; and one to three buckets were filled for each representat ive
sample. In addition, sites were also sampled using standard hammer and chisel rock
chip sampling for one to two kilograms of material.

HAM #2 5.26 85.9
BU1 0.12 48.9
BU2 0.06 58.4
ASP #1 14.42 28.5
Black Vein #1 5.34 67.3
Black Vein #2 0.16 68.1
The areas of interest are within a one kilometre elongate trend of historic mine workings
dating back to the late 1800’s and early 1900’s. Black Tusk contracted Carmen
Mucciarone Excavator Services that utilized a John Deere 200C excavator for the
trenching program. Each trench site comprised approximat ely 5 to 15 metres of pit and
trench to expose the target structure. A total of roughly 50 lineal metres of trenching
excavated approximately 375 cubic metres of material to expose the targets at the five
sites.
All samples were continuously under the control of the Qualified Professional on the
site, Perry Grunenberg, P.Geo. The large volume bucket samples were shipped to Met -
Solve Laboratories in Langley, BC. Rock samples were shipped to MS Analytical Lab in
Langley, BC, an ISO/IEC standard 17025:2005 accredited laboratory..
At Met -Solve Laboratories, samples were processed by their Bulk Gravity Assay
(MGBA) method , under the supervision of qualified person Jonathan Tan, P.Eng
(Metallurgical Engineer). The MGBA process utilizes centrifugal gravity concentration to
collect free “nugget” gold into a concentrate which gets assayed to extinction (in its
entirety). The gravity tailings, which would be void of the free gold, are then sub-
sampled in triplicate for assays. The head grade of the sample is then calculated based
on the concentrate and tailings products.
In addition to the larger samples , 10 normal sized rock samples were taken from
prospective outcrops and trenches along the 1000 metre corridor. The highest gold
value was from a chip sample across one metre of the Black Vein (BVINSITU) that
returned 13.15 g/T gold. This same vein, when sampled by the larger volume method
and processed at Met Solve, returned calculated grade values of 0.16 and 5.34 grams
per tonne gold. A result of 5.2 g/T gold from the arsenopyrite vein (ASPYINSITU) had a
corresponding 14.42 g/T gold from the Met Solve processing. These results indicate
that nugget effect is likely a factor for gold distribution within this corridor.

These preliminary results from the fall trenching program are very encouraging. The one
kilometre trend that contains historic small scale mining and significant exploration
results continues to provide evidence of unexploited gold mineralization along the
corridor. The abundance of quartz veins have been the focus of prior work, however,

the Black Tusk fall 2018 trenching and sampling program suggests that other veins and
structures may be of interest. These include shear zones with narrow quartz veinlets as
exposed in Trench 5 (Hamburger Vein), and massive sulphide veins such as the
Arsenopyrite and Black Vein.
The final report from Met Solve is expected in the following weeks. Explanation of the
process and further i nterpretation of the results with more details regarding the veining
system(s) will be compiled shortly thereafter.
Black Tusk routinely utilizes standards and blanks placed into the sample stream for
quality assurance, and evaluate the results for quality control. For this program, a single
standard and a single blank sample were submitted in the rock sample shipment. The
results indicate that both of these assurance measures passed evaluation for quality
control.
