Asiamet's Exceptional Zn-Pb-Ag-Au Drill Results Upgrade Potential of BKZ Discovery

Asiamet Resources Limited ("ARS" or the "Company") is pleased to announce that scout drilling at the BKZ prospect continues to intersect broad zones of near surface high grade base and precious metal rich mineralisation. Results received for step-out drilling along strike of earlier intersections (refer ARS Press Releases October 3, 2017) have exceeded all expectations and provide added confidence that the Company has potentially discovered a stand-alone high grade polymetallic Zn-Pb-Ag-Au deposit on its Kalimantan Surya Kencana ("KSK") 6th Generation Contract of Work ("CoW"), in Central Kalimantan, Indonesia. 

BKZ is located approximately 800m north and proximal to the main access road leading to the Company's feasibility stage BKM Copper Project. The discovery of thick, very shallow, high grade polymetallic mineralisation close to planned and propose infrastructure has the potential to transform the value of the KSK property and is considered to be a very significant development for the project and Company.

To date, seven holes (705m metres in total) have been drilled to test a zone of massive sulphide outcrops over an area of 150m x 100m. Highlights of the latest batch of drill results received include:


30.0m at 8.9% Zinc, 2.2% Lead, 46g/t Silver and 0.37g/t Gold (from 43 metres)

Including9.0m at 12.0% Zinc, 5.4% Lead, 94g/t Silver, 0.56g/t Gold (from 44 metres)

Including9.0m at 12.6% Zinc, 1.2% Lead, 28g/t Silver, 0.15g/t Gold (from 61 metres)

The first hole on section line BKZ33650 was drilled 50m south of BKZ33700-02 (113.9m End of Hole "EOH"), which intersected 39m at 7.3% zinc, 2.3% lead, 33g/t silver and 0.33g/t gold from 41 metres (refer ARS Press Releases October 3, 2017). BKZ33650-01 (113m EOH) intersected a broad zone of quartz-sulphide mineralisation from 43m depth, which outcrops approximately 50m to the east. The mineralisation comprises quartz-sulphide veins to massive sphalerite (zinc), galena (lead), chalcopyrite (copper) and pyrite (Figure 2). This intersection is consistent with the interpreted geometry of BKZ mineralisation observed in adjacent holes, indicating the quartz-sulphide body is approximately 40-50 metres in true thickness.

The results of BKZ33650-01 confirming high grade zinc-rich polymetallic mineralisation extends to the south of previous drilling is very promising. This is the highest-grade broad interval of zinc-rich mineralisation the Company has drilled to date and provides further evidence that polymetallic mineralisation is increasing in grade to the east. It also enhances our understanding of the structural and stratigraphic controls on the BKZ mineralisation which remains open laterally and to depth. Step-out drilling continues to the south and east and the drill rig is currently positioned on BKZ33650-02, testing the eastern extensions to the high-grade polymetallic mineralisation intersected in BKZ33650-01.

A drill hole location plan and a table of full assay results are provided in Figure 1 and Table 1 respectively.

Peter Bird, Asiamet's Chief Executive Officer commented:

"As the BKM Copper Project is being advanced through Feasibility Study, a pipeline of additional prospects on the KSK COW such as BKZ Polymetallic, Beruang Kanan West, Beruang Kanan South and Baroi represent high potential walk up drill targets of which some are to be progressively tested over the coming weeks and months. The Company views the recent results from drilling at BKZ, the first pipeline target to be tested in the current program, as a clear illustration of the substantial upside potential remaining on the very underexplored KSK COW. Work undertaken by the Company and its predecessor partners to date suggests that the greater BK area represents a polymetallic mineral district covering approximately 10-15 square kilometres, the potential of which is only beginning to see daylight. The discovery and delineation of the BKM copper deposit in the past three years and these recent exceptional grade polymetallic results from early drilling at BKZ highlight the potential to multiply the value of the KSK COW through systematic exploration. the Company is very excited by this opportunity and looks forward to unlocking this value for its stakeholders."

Glossary of Technical Terms

"anomaly or anomalous"

something in mineral exploration that geologists interpret as deviating from what is standard, normal, or expected.


The laboratory test conducted to determine the proportion of a mineral within a rock or other material. For copper, usually reported as percentage which is equivalent to percentage of the mineral (i.e. copper) per tonne of rock.


the "compass direction" refers to a geographic bearing or azimuth as measured by a magnetic compass, in true or magnetic north.


Bornite, also known as peacock ore, is a copper sulphide mineral with the formula Cu5FeS4.


Breccia is a rock classification, comprises millimetre to metre-scale rock fragments cemented together in a matrix, there are many sub-classifications of breccias.


Chalcocite is a copper sulphide mineral with the formula Cu2S, and is an important copper ore mineral. It is opaque and dark-gray to black with a metallic luster.


Chalcopyrite is a copper sulphide mineral with formula CuFeS2. It has a brassy to golden yellow colour.

"channel sample"

Samples collected across a mineralised rock exposure. The channel is typically orientated such that samples are collected perpendicular to the mineralised structure, if possible.


Chargeability is a physical property related to conductivity. Chargeability is used to characterise the formation and strength of the induced polarisation within a rock, under the influence of an electric field, suggesting sulphide mineralisation at depth.


The reporting standard adopted for the reporting of the Mineral Resources is that defined by the terms and definitions given in the terminology, definitions and guidelines given in the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral resources and Mineral Reserves (December 2005) as required by NI 43-101. The CIM Code is an internationally recognised reporting code as defined by the Combined Reserves International Reporting Standards Committee. 


Covellite is a copper sulphide mineral with the formula CuS. This indigo blue mineral is ubiquitous in some copper ores.

"diamond drilling"

A drilling method in which penetration is achieved through abrasive cutting by rotation of a diamond encrusted drill bit. This drilling method enables collection of tubes of intact rock (core) and when successful gives the best possible quality samples for description, sampling and analysis of an ore body or mineralised structure.


A line directed down the steepest axis of a planar structure including a planar ore body or zone of mineralisation. The dip has a measurable direction and inclination from horizontal.


grams per tonne; equivalent to parts per million ('ppm'). 


Galena is the natural mineral form of lead (II) sulphide, with formula PbS. It is the most important ore of lead and an important source of silver. It has a silver colour.

"grab sample"

are samples of rock material collected from a small area, often just a few pieces or even a single piece of rock "grabbed" from a face, dump or outcrop or roughly 2-5kg. These are common types of rock samples collected when conducting mineral exploration. The sample usually consists of material that is taken to be representative of a specific type of rock or mineralisation.


The proportion of a mineral within a rock or other material. For copper mineralisation this is usually reported as % of copper per tonne of rock (g/t).


Hypogene ore processes occur deep below the earth's surface, and form deposits of primary minerals, such as chalcopyrite and bornite.

"Indicated Resource"

An "Indicated Mineral Resource" is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

"Induced Polarisation Geophysics"

Induced polarisation (IP) is a geophysical survey used to identify the electrical chargeability of subsurface materials, such as sulphides. The survey involves an electric current that is transmitted into the subsurface through two electrodes, and voltage is monitored through two other electrodes.

"Inferred Resource"

An "Inferred Mineral Resource" is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.


Refers to a sample or sequence of samples taken across the entire width or an ore body or mineralised zone. The intercept is described by the entire thickness and the average grade of mineralisation.


Pounds (measure of weight)


In a geological sense, refers to a zone of mineralisation that is dominated by sulphide minerals. The sulphide-mineral-rich material can occur in centimetre-scale, meter-scale or in tens of meters wide veins, lenses or sheet-like bodies containing sphalerite, galena, and / or chalcopyrite etc.

"Measured Resource"

A "Measured Mineral Resource" is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.

"Mineral Resource"

A "Mineral Resource" is a concentration or occurrence of diamonds, natural solid inorganic material, or natural solid fossilised organic material including base and precious metals, coal, and industrial minerals in or on the Earth's crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge.


In geology, mineralisation is the deposition of economically important metals (copper, gold, lead, zin etc) that in some cases can be in sufficient quantity to form mineral ore bodies.


Million pounds (measure of weight)

"open pit mining"

A method of extracting minerals from the earth by excavating downwards from the surface such that the ore is extracted in the open air (as opposed to underground mining).


A section of a rock formation or mineral vein that appears at the surface of the earth. Geologists take direct observations and samples from outcrops, used in geologic analysis and creating geologic maps. In situ (in place) measurements are critical for proper analysis of the geology and mineralisation of the area under investigation.


Three or more metals that may occur in magmatic, volcanogenic, or hydrothermal environments; common base and precious metals include copper, lead, zinc, silver and gold.


A geology term, often applied to breccias or conglomerates, which identifies the composition as consisting of fragments of several different rock types.

"Preliminary Economic Assessment"

NI 43-101 defines a PEA as "a study, other than a pre-feasibility study or feasibility study, which includes an economic analysis of the potential viability of mineral resources".


Sedimentary rocks formed by 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 is a zinc sulphide in crystalline form but almost always contains variable iron, with formula (Zn,Fe)S. It can have a yellowish to honey brown or black colour.


Supergene ore processes occur near surface, and form deposits of secondary minerals, such as malachite, azurite, chalcocite, covellite, digenite, etc.

"surface rock chip samples"

Rock chip samples approximately 2kg in size that are typically collected from surface outcrops exposed along rivers and mountain ridgelines.


A vein is a sheet-like or anastomosing fracture that has been infilled with mineral ore (chalcopyrite, covellite etc) or mineral gangue (quartz, calcite etc) material, within a rock. Veins form when minerals carried by an aqueous solution within the rock mass are deposited through precipitation and infill or coat the fracture faces.


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 is deposited as volcaniclastic or pyroclastics.
