Asiamet BKZ Resource Drilling Continues to Intersect High Grade
Mineralisation
Asiamet Resources Limited ("ARS" or the "Company") is pleased to
report that ongoing Resource delineation drilling at the BKZ
prospect ("BKZ") continues to intersect high-grade polymetallic and
copper - silver mineralisation as predicted. The BKZ prospect is

silver over 1-metre sample intervals in the polymetallic zone and
up to 6.6% copper over 1-metre sample intervals in the interpreted
"Feeder Structure" in the Lower Zone
-- A Maiden Resource estimate for both mineralised domains at
the BKZ deposit is being prepared by Hackman & Associates Pty
Ltd and is expected to be completed in May 2018

The Maiden Resource drilling programme at BKZ continues to
provide confidence in the strike, dip and internal continuity of
the high-grade polymetallic and underlying copper-silver
mineralisation. A total 3,416 metres in thirty-six holes were
completed for the first of a two-phase drilling campaign at BKZ,
where mineralisation continues to define the dimensions of the two
mineralised domains at BKZ, the footprint of which still remains
open in several directions. The analysis from the final five drill
holes is expected in March 2018, and the Company is on track to
report a Maiden Resource estimate for the BKZ deposit in May 2018,
which is being carried out by Independent consulting geologist
Duncan Hackman of Hackman & Associates Pty Ltd.
Peter Bird, Asiamet's Chief Executive Officer commented:
"The excellent results generated from our drilling programmes at
both the BKM and BKZ projects over the past three years clearly
demonstrate the intrinsic value of Asiamet's project portfolio.
This latest batch of results from Resource delineation drilling at
BKZ demonstrate excellent internal continuity of both the upper
high-grade polymetallic and the underlying copper-silver
mineralisation and increase the Company's confidence in defining an
initial high value polymetallic deposit with potential to leverage
off the proposed BKM mining infrastructure. With the recent
financing completed we look forward to reporting further results
from the BKZ infill drilling programme and the initial Resource in
May, together with further results from the final stages of the BKM
bankable feasibility study and first results from our current
programme of drilling and metallurgical testwork underway at the
Beutong porphyry Cu-Au deposit."
Drill Hole Summary
The fifth hole on section line BKZ33700 was drilled to confirm
continuity of mineralisation in BKM33700-03 (101.3m End of Hole
"EOH"), which intersected 30.0m at 8.3% zinc, 3.3% lead, 39g/t
silver and 0.51g/t gold from 14m (refer ARS Press Release October
18, 2017). BKZ33700-05 (94.2m EOH) was drilled eastward and
intersected a broad zone of moderate to high-grade polymetallic
mineralisation from 4.0m depth comprising quartz-sulphide veins and
massive sulphides containing sphalerite (zinc), galena (lead),
chalcopyrite (copper) and pyrite. The sixth hole on section line
BKZ33700 is a scissor hole to BKM33700-02 (113.9m EOH), drilled to
confirm continuity of high-grade mineralisation that included 39m
at 7.3% zinc, 2.3% lead, 33g/t silver and 0.33g/t gold from 41m
(refer ARS Press Releases October 3, 2017). BKZ33700-06 (72.0m EOH)
was drilled eastward and intersected a broad zone of moderate to
high-grade polymetallic mineralisation from 34.0m depth comprising
quartz-sulphide veins and massive sulphides containing sphalerite
(zinc), galena (lead), chalcopyrite (copper) and pyrite. This hole
intersected some of the highest grade polymetallic assays seen to
date, with up to 30.7% zinc, 17.7% lead and 158g/t silver in a
1-metre sample interval.
The fourth hole on section line BKZ33600 was drilled parallel to
BKZ33600-02 (89.6m EOH), which intersected a broad zone of
copper-silver mineralisation assaying 29.3m at 1.52% copper,
0.15g/t gold and 40.1g/t silver from 59.0m and includes 19.0m at
1.97% copper, 0.14g/t gold and 19.0g/t silver from 61.0m depth
(refer ARS Press Release November 13, 2017). BKZ33600-04 (92.1m
EOH) was targeting the area below the hematite rich zone, but
unfortunately the rig was unable to breach this intensely
silicified rock. However, BKZ33600-04 did intersect higher grade
copper-silver mineralisation than was reported in BKZ33600-02, the
interpreted feeder zone comprising a dense stockwork of
quartz-sulphide and sulphide veins containing bornite, chalcopyrite
and pyrite. Individual 1-metre sample intervals assayed up to 6.6%
copper within the higher grade interval from 63m to 81m depth. The
fifth hole BKZ33600-05 (115.8m EOH) was also drilled east, but at a
shallower angle. This hole also intersected the interpreted feeder
zone, comprising a dense stockwork of quartz-sulphide and sulphide
veins containing bornite, chalcopyrite, galena and pyrite. This
hole also terminated in the intensely silicified and hematite
altered breccia, with assays confirming gold-silver
mineralisation.
The drill hole location plan map and a table of full assay
results are provided in Figures 1 and Table 1 respectively.

Notes: Grade intercepts are calculated as a weighted average
grade >=1.0% Zinc (uncut) for Polymetallic Zone. Grade
intercepts are calculated as a weighted average grade >=0.2%
Copper (uncut) for the Copper-Silver Zone. True widths are
interpreted to be between 80-100% of the reported lengths, unless
otherwise stated. Orientation of the polymetallic mineralised
domain is interpreted to have an azimuth of 340 degrees and a dip
of -25 degrees to the northeast. Orientation of the copper
mineralised domain is interpreted to have an azimuth of 340
degrees, a dip of -25 degrees to the northeast and plunging
south-southeast.

---------------------------- -----------------------------------------------
"outcrop" A section of a rock formation
or mineral vein that appears
at the surface of the earth.
Geologists take direct observations

study or feasibility study,
which includes an economic
analysis of the potential
viability of mineral Resources".
---------------------------- -----------------------------------------------
"propylitic alteration" Propylitic alteration is the
chemical alteration of minerals
within a rock, caused by hydrothermal
fluids. This style of alteration

altering biotite or amphibole
minerals within the rock groundmass.
It typically occurs along
with pyrite.
---------------------------- -----------------------------------------------

the accumulation of sediments.
There are three types, Clastic,
Chemical and Organic sedimentary
rocks.
---------------------------- -----------------------------------------------
"sequential assays" Sequential copper analysis
is a technique to semi-quantitatively
define the zonations associated
with some copper deposits.
The method is based on the
partial dissolution behaviour
displayed by the prevalent
copper minerals to solutions
containing sulphuric acid
and sodium cyanide. Results
from sequential analyses can
theoretically determine the
amounts of leachable oxide
minerals, leachable secondary
sulphide minerals, and primary
copper minerals, respectively.
---------------------------- -----------------------------------------------
"sphalerite" Sphalerite is a zinc sulphide
in crystalline form but almost

anastomosing fracture that
has been infilled with mineral
ore (chalcopyrite, covellite
etc) or mineral gangue (quartz,

carried by an aqueous solution
within the rock mass are deposited
through precipitation and
infill or coat the fracture
faces.
---------------------------- -----------------------------------------------
"volcanics" Volcanic rock such as andesite
or basalt that is formed from
magma erupted from a volcano,
or hot clastic material that
erupts from a volcano and
