Asset Overview

The Company’s 357 km ( 35,700 hectares) 3 Aces gold district, located in southeast Yukon is 100% owned, subject to underlying royalties, is located 40 km south of the Cantung Mine and is road accessible via a newly constructed bridge that will allow for year-round work programs.

Initial exploration efforts have been primarily focused on drill-testing initial vein discoveries identified through extensive trenching.  Additional target definition and refinement has been accomplished with  airborne geophysics, detailed geological mapping and additional soil sampling.

Previous results from the first two vein discoveries, the Ace of Spades Vein and the Ace of Hearts, have yielded grab samples up to 4,820 including several +1,000 g/t samples. A 2016 bulk sampling program focused on the Aces of Spades vein and confirmed high-grade drilling results.

Subsequent field work within the 10 km2 Central Core Area of the 225km2 project has identified more than twenty new veins, of which five have visible gold and is the  target for drilling during the 2016-2017 campaign. Concurrently, airborne geophysics has been completed over a large portion of the remaining 215km2 project area to identify favorable structural controls with potential to host mineralization while soil sampling coverage has been expanded in the underexplored northern portion of the property with the goal of identifying new gold occurrences.

The Company completed 54 holes during winter 2016 drill program for a total of 4,315 m, which included 3,776 m of reverse circulation drilling utilizing a larger 5.5 inch center face-return hammer drill bit and 539 m of PQ-size (3.35 inch) diamond core drilling. 52 of the 54 drill holes reached their targeted depths. A 20,000 meter drilling program is planned to continue in 2017.

The 3 Aces project operates under a Class 4 Mining Land Use Permit.

Orogenic Model

The 3 Aces Project: An Evolving Orogenic Gold Deposit Model

The 3 Aces Project (3 Aces) in Canada’s Yukon Territory features high-grade visible gold-bearing quartz veins and is the flagship project for Golden Predator Mining Corp. (Golden Predator).

Yukon Territory

During initial exploration on the property, the outcropping occurrences although abundant, appeared to be small and unrelated. Further exploration work confirmed that there is a structural and lithological setting that connects these occurrences. A systematic pattern emerged, and this pattern correlates the vision that the occurrences are not only related, but that they stretch both laterally and vertically. This led the technical team at Golden Predator to develop a conceptual Orogenic Gold Deposit Model that highlights the district scale potential at the 3 Aces Project.

District Scale Potential

At 3 Aces, the exploration has been focused on the Central Core Area. This area is 11km2 and contains a broad gold-in-soil anomaly where more than 25 gold-bearing quartz veins have been discovered to date.

Central Core Area:

Central Core Area 1 Central Core Area 2

The Central Core Area only represents 3% of the 357km2 3 Aces Project which spans approximately 40 km north to south. The technical team believes that the systematic pattern that occurs in the Central Core Area could potentially occur throughout much of the property. To further support this, a new gold-in-soil anomaly was identified along the strike to the north-northwest, approximately 7km from the Central Core Area (Fall 2016). Carrying on along the trend in the same direction, Golden Predator recently acquired two new land packages that feature soil data with similar rock units and style of gold mineralization, where rock samples have assayed up to 149 g/t of gold.

Orogenic Gold Deposit 

Gold mineralization at 3 Aces is orogenic in nature. Orogenic deposits are formed during the mountain building process and through the collision of continental plates. Orogenic deposits account for some of the largest gold deposits around the world, such as the California Mother Lode Belt and the Juneau Gold Belt.

The collision of continental plates push rocks deep within the Earth’s crust where they are subjected to high temperatures and high pressures. This environment causes physical and chemical changes (metamorphism) to the rocks and liberates the gold bearing, and other trace element-enriched, fluids. These gold bearing fluids then migrate upwards, working their way into cracks, faults and shears. This leads to the deposition of quartz and gold in the form of veins. Open spaces (dilation) combined with low-pressures, create a favorable environment conducive to the formation of these gold-bearing quartz veins.

Gold Deposition at the 3 Aces Project, Yukon

Three styles of gold deposition have been identified while exploring the Central Core Area.  

1. Bedding-parallel quartz veins along shear zones, featuring low angle faults.

These veins are found among Proterozoic meta-sedimentary rocks including sandstone and phyllite. Compressional tectonics acting on these types of rocks cause movement along the original bedding planes. The movement causes major shear zones and facilitates the formation of open spaces which are enhanced because different rock types are in contact with one another (sandstone and phyllite). We have observed indicators that identify at least three major parallel shear zones stacked 200 or 300 metres above one another featuring low angle faults. There are multiple quartz veins which occur in or near these shear zones, that span up to 7 metres wide with grades anywhere from 1 g/t, to more than 10 g/t of gold.

Conceptual Model

2. Quartz veins occurring at high angle orientations with conjugate geometries.

These veins were formed between the bedding-parallel shear zones as tensional (pulled apart) stress release faults and fractures. Stress release faults and fractures tend to be found at predictable orientations (north-east, west-northwest and east-west). These veins range up to 10 metres thick and host grades ranging from 15 g/t, to more than 30 g/t of gold.

3. Stockwork veins developed in brittle sandstone or conglomerates.

This style is typical of a lower grade deposit and could potentially be a bulk minable target. At 3 Aces, it has been noted in several drill holes.

Following high-grade, high angled veins to their intersection with bedding-parallel veins is a prime target which, if confirmed by additional drilling, could identify zones of concentrated gold mineralization (shoots).

The 3 Aces Project: An Evolving Orogenic Gold Deposit Model Summary

Additional drilling and sampling work is required to confirm the extent and grade of mineralization at the 3 Aces Project. The goal is to find additional veins, confirm the extent of the high angle veins already identified, and establish the importance of the stockwork mineralization.

The technical team at Golden Predator is committed to testing and refining the conceptual Orogenic Gold Deposit Model that features a structurally and lithologically controlled, orogenic type gold-bearing quartz veining, occurring in repeating or stacked zones of mineralization.


Compressional Tectonism: Tectonism or tectonics describes the movements and evolution of the earth’s crust which is divided into tectonic plates over time. Compressional tectonics are when plates converge or collide with one another creating compressional forces.

Conjugate geometries: When compressional forces act on rocks conjugate geometries describes the mathematical pattern of faults, fractures or breaks that can occur in the rocks.  It is a predictable pattern and replicates itself throughout the area of compressional force. Coupled, predictable patterns of rock deformation, typically fractures or faults, commonly associated with compressional forces.

Country Rocks: Country rocks are the unmineralized rocks that occur in association with mineral deposits.

g/t: grams/tonne is grams per metric tonne and is equal to ppm (parts per million).

Lithology: The type of rocks, defined by mineral composition and texture.

Metamorphism: The process of altering the chemical or mineralogical composition of a rock by pressure and temperature in the earth's interior.

Outcropping Occurrences: Any place where bedrock is visible on the surface of the Earth.

Phyllite: A metamorphic rock, intermediate in grade between slate and mica schist.  The mineral grains are typically flat and shiny.

Proterozoic: The geologic eon between the Archean and Phanerozoic eons, beginning about 2.5 billion years ago and ending 542 million years ago.

Sandstone: Sedimentary rock composed of small grains of mainly quartz and feldspar bound together by silica, carbonate, or clay minerals.

Shear Zones: A tabular zone of rock that has been crushed and brecciated by many parallel fractures due to shear strain. Such an area is often mineralized by ore-forming solutions.

Shoot: A body of ore, usually of elongated form, extending downward or upward in a vein. Also known as an ore shoot.

The 3 Aces Project is host to high grade quartz veins, some with visible gold.  Surface exploration since August, 2016 has been highly successful with the discovery of at least twenty new  quartz veins. Prior to 2016, exploration had focused primarily on just the Ace of Spades and Ace of Hearts zone.

The first high-grade showing explored within the project is the Ace of Hearts vein, where several +1,000 g/t specimens, were taken from the outcrop. Between 2010 and 2012 this vein has been drilled along strike for 275 meters and 275 meters downdip. Additionally, the Aces of Spades vein was drill tested in 2016 where 30 of 31 holes intersected significant gold mineralization including hole 3A16-RC-015 that intersected 11.4m of 31.89 g/t Au.

Systematic geologic mapping and trenching have shown that veins of certain orientations in specific stratigraphic packages yield the most encouraging assays and have been prioritized for drilling.  Further property-wide exploration will focus on these unique factors as guides to additional mineralization.

Initial results from new veins discovered as part of this program included the Jack of Spades, which returned some of the highest gold grades to date including 186.5 g/t Au, 94.7 g/t Au and 64.3 g/t Au. The Clubs area is located approximately 2 to 2.5 km northwest of the Jack of Spades vein, also produced a new discovery, the Queen of Clubs vein, which contains visible gold and assayed 12.9 g/t gold over a 1.0 metre channel sample and 111 g/t gold over a 20 cm channel sample.

A large-scale soil sampling program has identified areas outside of the 10 km2 core area that have potential to host multiple new vein discoveries. These anomalies will be the focus of a follow-up trenching program to be conducted in 2017 in order to identify new gold-rich veins.

The 3 Aces Property is located in the Selwyn Basin; a lenticular belt of sedimentary rocks that extends across the Yukon. The property is underlain by interbedded clastic and carbonate sedimentary rocks of the Hyland Group, the basal unit of the Selwyn Basin. The stratigraphic sequence is assigned to the Yusezyu and Narchilla formations; although recent regional mapping suggests a distinct package of calcareous sedimentary rocks occurs between the two classic formations of the Hyland Group. Polyphase fold and fault systems overprint the stratigraphy, structurally preparing the rocks for later hydrothermal fluids and acting as pathways for the mineralizing fluids. Gold mineralization along with minor sulphides (i.e., pyrite and arsenopyrite) mineralization occurs along late, brittle faults formed within an extensional step-over zone between two regional dextral trans-extensional faults. Mineralised hydrothermal fluids migrated through these faults during late phases of brittle fault displacement. Gold mineralization on the property is associated with extensive argillic, iron carbonate, and limonitic alteration zones that broadly overprint the stratigraphy and early structural fabrics.

The current exploration strategy on the 3 Aces Property is based on the metallogenic models developed for orogenic gold deposits. These types of deposits have been described extensively throughout the northern Cordillera of Alaska and BC (e.g., Groves et al., 1998; Kerrich, 2000; Goldfarb et al., 2001; Goldfarb et al., 2004), but have not been extensively explored for in Yukon Territory. The primary characteristics of the 3 Aces Property that make the orogenic gold model an appropriate analogy for the property are: mid- to upper-crustal level crack-seal style quartz veins, high competency contrast between lithologies, transextensional crustal-scale regional faults that provide fluid pathways for deeply sourced metamorphic fluids, and a prolonged polyphase deformation history that allowed multiple generations of fluid to pass through the region.

Metallurgical Testing

Mineralization encountered to date consists primarily of free gold in quartz veins. Initial metallurgical testwork in 2014 on a 530 kilogram portion of the Ace of Spades vein indicated a recovery of 78.9% by simple gravity methods. CN leaching of the tails from the sample brought overall gold recovery to 97.9%. An approximately 750 tonne bulk sample was collected in February 2016 from the Ace of Spades vein and a total of 79.70 dry tonnes (87.83 dry tons) were processed intermittently through July 12th, 2016. A total of 4,587 grams of concentrate were recovered from the shaker tables, which was poured into a doré bar which contained 81.408 troy ounces of fine gold and 7.771 troy ounces of silver.  Calculated gravity recoverable gold from analysis of daily head and tails samples returned values of 80.8% to 92.8% confirming that high recoveries can be obtained by simple gravity processing.

Reef Property

Reef  Property
Location Southeastern Yukon, 200 km North of Watson Lake
Summary Sediment Hosted Gold Mineralization (Orogenic)

Exploration completed by Westmin Resources (1996-97), Rimfire (1998), Strategic Metals (2010) and Precipitate (2011-12) has established an extensive gold-arsenic-antimony soil anomaly measuring at least 3 km long; with gold values exceeding 1,000 ppb.

During the 2011-12 field seasons, Precipitate completed airborne magnetics and radiometric surveys, 3D inversion modeling of the magnetic data, and multiple phases of rock-silt-soil geochemical sampling and geological mapping and prospecting. This work has given technical staff a better understanding and appreciation of the structural and lithologic controls on the gold mineralization. In late 2012, work focused on the priority Fer Zone, where detailed geological mapping and rock sampling, additional soil sampling and prospecting on extensions of the South and Northeast soil anomalies and also extended new coverage over the Camp Cirque area was completed. Interpretation these geochemical and geological results indicates that future work should focus on the overlapping gold-arsenic anomalies of the Camp Cirque and Northeast areas. Additional exploration work will be needed to develop high merit drill targets. In preparation for a possible future drill program, the Company has the necessary permits and studies in-place. These include a five-year Class 3 Mining Land Use Permit from the Yukon Government (dated April 2012), a property-wide desktop Heritage Resources Overview Assessment (HROA) and a preliminary field archaeological reconnaissance report for preferred roadside camp locations.

Location, Infrastructure, Access & Ownership

The Reef Property is located in the southeastern Yukon, about 200 kilometers north of Watson Lake. The property covers an area of 8,615 hectares and is comprised of 418 claims owned by or under option to Precipitate Gold. Reef is accessible via the Cantung Mine Road that provides access to the Cantung tungsten mine located about 20 kilometers east of the project. The claims are both road and helicopter accessible, plus chartered fixed wing aircraft can land on the Hyland airstrip located 50 kilometers south.  

Geological Setting and Mineralization

Reef is located at the southeast end of the Tombstone Gold Belt within sedimentary rocks of the lower Selwyn Basin. Reef claims are underlain by Neoproterozoic to middle Cambrian aged Hyland Group sedimentary rocks composed primarily of siliclastic lithologies, with sections of calcareous sandstone and limestone. Reef is positioned in the northern portion of the Upper Hyland Gold Trend; a +50 kilometre long region of gold mineralization, which includes a number of other reputable gold occurrences, such as the Hy, 3 Ace, Sprogge and Justin. Discovered in the late 1990s, Upper Hyland Gold Trend mineralization is dominantly found within favourable sedimentary host rocks which have undergone extensive regional structural modification ("Little Owls Anticlinorium") creating favourable zones of dilation or fluid pathways. Distal or deep buried intrusive bodies are possible sources of the Trend's gold mineralizing fluids. Gold typically is found in zones of quartz veining and extensive silica flooding and is associated with variable but generally low amounts of pyrite, arsenopyrite and trace amounts of other base metals.

Exploration completed by Westmin Resources (1996-97), Rimfire (1998), Strategic Metals (2010) and Precipitate (2011-12) has established an extensive and open ended gold-arsenic-antimony soil anomaly measuring at least 3 km long; with gold values exceeding 1,000 ppb. In 1996, Westmin collected rock chip samples over an 8.0 metre long interval that returned 1.97 ppm gold.
