Asiamet Intersects Broad Copper Intervals at Beutong -
Identifies Exciting Deep Drill Target
Asiamet Resources is pleased to report the latest assay results
from drilling completed on its 80% owned, Beutong Cu-Au porphyry
project in Indonesia.
Results from hole BEU1450-01 drilled at the Beutong West
Porphyry ("BWP") include:
-- 596.6m at 0.53% CuEq from 153.4m
-- Including 79.0m at 0.84% CuEq from 155m
-- Including 54.5m at 0.73% CuEq from 245.5m
-- Including 62m at 0.75% CuEq from 540m
Extensive oxide gold mineralization was also intersected from
near surface above the copper mineralisation including 136.0m at
0.46 g/t Au from 2.0m. Potential of this shallow gold
mineralisation atop the BWP will be assessed with further
drilling.
The hole was terminated at a depth of 750 metres due to rig
capacity with mineralisation remaining open at depth and
laterally.
The 2018 drill program has proven highly successful with all
seven holes (3,528 metres) drilled to date intersecting wide
intervals of porphyry copper-gold-molybdenum mineralisation which
has significantly increased confidence in the Beutong Resource
model and identified targets with potential to significantly expand
the size of the current deposit. Drill holes testing between the
Beutong East Porphyry ("BEP") and the Beutong West Porphyry ("BWP")
have confirmed broad zones of copper mineralisation extending to
depth outside the current Resource Envelope and additional drilling
is required to fully explore the potential in this area prior to
updating the Resource.
As the drilling program has progressed and the potential for a
coalescence of the BEP and BWP at depth has been recognised,
further modelling of ground magnetic data has been completed and
selected drill holes have been relogged. A strongly magnetic body
has been modelled immediately beneath the central core of the
system, overlapping with the base of the BEP. Previous work clearly
identified a zoned system at Beutong with some of the holes in the
BEP and BWP reporting increasingly elevated copper-gold +/-
molybdenum grades with depth e.g. BEU0700-03 148m at 0.80% Cu,
0.15g/t Au, 98 ppm Mo from 146m and 110.7m at 0.76% Cu, 0.13g/t Au,
129ppm Mo.

This apparent zonation in mineralisation, combined with presence
of a highly mineralised chalcopyrite-bornite-magnetite clast within
diatreme breccia proximal to the modelled large magnetic feature is
considered highly significant and requires further testing with a
series of deep holes. The deep, highly magnetic, potassic altered
cores in some of the giant high grade porphyry copper-gold systems
such as Newcrest's Wafi-Golpu (PNG) and Solgolds Cascabel (Equador)
host the highest grade bornite-chalcopyrite mineralisation.
Peter Bird, Asiamet's Chief Executive Officer commented:
"The 2018 drilling program at Beutong has consistently met or
exceeded expectations and provided greatly improved definition
across the Beutong East and Beutong West porphyry deposits. The two
systems remain open in multiple directions with recent drilling
suggesting they may coalesce at depth.
Strong copper, gold and molybdenum grades and the presence of
highly mineralised magnetite bearing breccia clasts proximal to a
large magnetic feature modelled below current drilling are very
exciting as such features are often associated with the high grade
cores of world class porphyry systems such as Newcrest's Wafi-Golpu
and Solgold's Cascabel.
As such Asiamet is evaluating various options including
partnering to test this deeper potential and more rapidly progress
the development of Beutong in the near term."

Notes: Grade intercepts are calculated as a weighted average
grade above 0.2% Copper (uncut). Broad intercepts calculated with
up to 10m internal dilution. True widths of downhole interval
lengths are estimated to be between 50-70% of the reported lengths,
unless otherwise stated. Orientation of the Beutong mineralised
complex is interpreted to have an azimuth of 250-260 degrees and is
steeply dipping to the north-northwest. Copper equivalent (CuEq)
values have been calculated using the equation CuEq = Cu+(Mo
ppm/10000 * 2.9412) + (Au g/t * 0.5204) + (Ag g/t * 0.0055) at a
copper price of US$3.00/lb, a gold price of US$1300/ounce a silver
price of US$16/ounce and a Molybdenum price of US$10/pound. Copper
Equivalent (CuEq) is used for illustrative purposes and do not take
into account copper or gold recoveries.

and evaluation of the economic viability of the deposit.
Geological evidence is derived from adequately detailed
and reliable exploration, sampling and testing gathered
through appropriate techniques from locations such as
outcrops, trenches, pits, workings and drill holes,
and is sufficient to assume geological and grade (or

It is based on exploration, sampling and testing information
gathered through appropriate techniques from locations
such as outcrops, trenches, pits, workings and drill
holes.
An Inferred Mineral Resource has a lower level of confidence
than that applying to an Indicated Mineral Resource
and must not be converted to an Ore Reserve. It is reasonably

etc.
------------------------------------------------------------------------
"Measured A 'Measured Mineral Resource' is that part of a Mineral
Resource" Resource for which quantity, grade (or quality), densities,

Factors to support detailed mine planning and final
evaluation of the economic viability of the deposit.
Geological evidence is derived from detailed and reliable
exploration, sampling and testing gathered through appropriate
techniques from locations such as outcrops, trenches,
pits, workings and drill holes, and is sufficient to
confirm geological and grade (or quality) continuity
between points of observation where data and samples
are gathered.
A Measured Mineral Resource has a higher level of confidence
than that applying to either an Indicated Mineral Resource
or an Inferred Mineral Resource. It may be converted
to a Proved Ore Reserve or under certain circumstances
to a Probable Ore Reserve.
