Introduction
Junior exploration companies in Yukon continued to brace themselves against unfriendly equity
markets. Exploration spending decreased from $80 million in 2014 to $61 million in 2015. It
should be noted, however, that a single large project can skew the exploration spending numbers
in a small jurisdiction like Yukon. Selwyn-Chihong Mining Ltd. spent $32 million on exploration in
2014 (40% of total exploration spending for that year), but just over $8 million in 2015.

Exploration Projects (precious metals)
Capstone’s Minto mine site from the air
Bellekeno Mine & Keno Hill deposits - Alexco Resource Corp.

(e.g., Flame & Moth and Lucky Queen) are being advanced. Engineering and permitting activities
are underway for the Flame & Moth deposits.
Wolverine Mine - Yukon Zinc Corp.

The Wolverine Mine was placed on care and maintenance in January 2015.
Lonestar - Klondike Gold Corp.
Orogenic gold. Diamond drilling (19 holes, 1374 m) on targets with visible
gold in quartz veins. Drill hole EC15-10 near Gay Gulch intersected 75.6 g/t Au
over 2.8 m. The company also carried out a drone orthophoto survey, 1000 m
of induced polarization and remediated historically disturbed areas.
MARIPOSA

Dublin Gulch (Olive zone) - Victoria Gold Corp.
Intrusion-related gold. Metallurgical testing on Olive zone drillcore
demonstrated favourable heap recoveries. Resource estimate on Olive zone
underway to be later incorporated into an updated feasibility study.

The Minto Mine is the only hard rock mine currently operating in
Yukon. In August 2015, the company received its water use
licence to allow for stripping at the Minto North deposit. Capstone
expects to start supplementing the mill feed with Minto North ore in
Q4 2015.

MINING AND EXPLORATION PROJECTS
There were 14 drill programs in the territory this year, an increase from the 10 drilled projects of
the previous year. Of the 85 exploration projects, 11 projects are projected to spend over a million
dollars. Almost 60% of exploration programs were searching for gold; the remainder for lead, zinc,
copper, nickel, silver, platinum group metals and jade.
Levels of funding for the Yukon Mineral Exploration
Program (YMEP) remained at C$1.4 million. This
program is consistently oversubscribed. The funds
were distributed to 48 placer and hard rock
exploration projects to offset exploration costs.
Although some companies dropped out of the
program early on due to the inability to raise
matching funds, several late season programs were
able to receive funding.
Exploration Projects (precious metals cont’d)
Coffee property - Kaminak Gold Corp.
Orogenic gold. Working toward feasibility
(expected Q1 2016). Completed 70 000 m of infill
drilling on four of the main deposits in 2015.
Updated resource (Sept 2015): 52.4 Mt @ 1.68 g/t
Au (2,824,000 oz) indicated and 42.7 Mt @ 1.52 g/t Au
(2,088,000 oz) inferred. Engineering work is
well underway.
Plateau South - Goldstrike Resources Ltd.
Vein gold. Shallow drilling (11 holes, 924.1 m) at Goldstack and Gold Dome
prospects. At Goldstack, a 30 m step-out hole (PSGS15-01) assayed
13.5 g/t Au over 17.5 m (from 22.0 - 39.5 m) and remains open at depth.
Mt. Good and North Rackla - Cantex Mine Development Corp.
Vein gold. 156 Rotary Air Blast drill holes at North Rackla. Fire assays of RAB
samples up to 183 ppb Au. Infill soil-talus sampling at Mt. Good and North
Rackla - results are pending.

drilling and exploratory step-out holes at the ABM and GP4F
deposits. Relogged 19 000 m of historic drillcore, 75 line km
of ground gravity and a VTEM survey. Advancing project
through pre-feasibility in 2016.
Geologists at the Kudz Ze Kayah exploration camp
Hopper property - Strategic Metals Ltd.
Copper-gold skarn and porphyry. Historic drilling identified shallowly dipping copper-rich skarn
horizons. Deeper drilling in 2015 intersected gold-rich new horizons (e.g., DDH 15-01 - 12.15 g/t Au
and 0.95% Cu over 2.65 m (true thickness)), 340 m north-northwest of historic drilling.

2015; however, Minquest released updated JORC-compliant resources based on refined geological
interpretations for both properties in 2015 and plans to complete a scoping study on the Marg project
by the end of 2015.
