Treasury Metals Files NI 43-101 Updated Preliminary Economic

Assessment on the Goliath Gold Project

Toronto, Canada – Treasury Metals Inc. (TSX: TML) (“Treasury” or the “Company”) has filed on

SEDAR a National Instrument 43 -101 updated Preliminary Economic Assessment (“PEA”) on its

Goliath Gold Project (“Goliath” or the “Project”) located in northwestern Ontario. The PEA, announced

on March 8, 2017, was prepared by CSA Global Canada Geo sciences Ltd. (“CSA Global”) with the

assistance of P&E Mining Inc. and the Company’s operations and exploration teams (see Qualified

Persons section below). The updated PEA integrates recent engineering and incorporates the 2015 NI

43-101 Mineral Resource Estimate from the Goliath Gold Project (“Updated Mineral Resource”).

Highlights of the PEA included (all currencies are reported in Canadian dollars unless otherwise

specified):

● The updated 2017 PEA benefits from increased mineable resources with the Updated

Mineral Resource and a higher grade profile while using a more conservative approach

related to all mining costs, capital costs and dilution compared with the 2012 PEA;

● Significantly improved economics with an after-tax NPV at a 5% discount of C$306 million

and IRR of 25% at US$1,225 per ounce gold (Au);

● The PEA benefits from a 37% increase in the Life of Mine (“LOM”) gold production

profile;

● Average an nual production of 87,850 oz Au over a 13 year combined open pit and

underground mine life; peak production exceeding 100,000 oz per year Au from Years 3-6;

● LOM head grade of 3.81 g/tonne Au, an increase of 33% from the 2012 PEA; and

● Attractive total cash cost is estimated at US$525 per equivalent gold ounce (“AuEq”) and an

all-in sustaining cost (“AISC”), as defined by the World Gold Council, estimated at US$611

per AuEq;

Goliath is located in northwestern Ontario, lying 20 kilometres east of the city of the Dryden. The total

area of the Project is 49 km 2 and is owned 100% by the Company. The site benefits significantly from

excellent access to infrastructure and is directly adjacent to the Trans -Canada highway and Canadian

Pacific Railway. The Project ha s access to electrical and natural gas power, rail, paved roadways to site

and several nearby communities.

The mining plan used in the PEA envisions an optimized open pit generating immediate revenues to

fund underground development. Underground (“UG”) pro duction begins in the second year with the

open pit operating over an additional seven years at a reduced output to supplement UG production to a

total of 2,500 tonnes per day over the course of a 13 year total mine life. Total gold production is

estimated at 1.14 million ounces of gold and 2. 1 million ounces of silver. Initial capital to fund

construction is estimated at C$133.2 million with an additional C$132.5 million in sustaining capital

over the LOM primarily to fund the underground expansion.

The mine is proposed to produce an average head grade of 3.81 g/t gold and 10.55 g/t silver with Open

Pit and UG mining producing average grades of 1.58 g/t and 4.87 g/t of gold, respectively. The infill

diamond drilling programs completed since the PEA co mpleted by Treasury in 2012 (the “2012 PEA”)

has resulted in improved project economics and overall confidence in the mine plan. The stripping ratio

of waste rock to ore has been reduced to 6:1, which represents a 35% improvement over the 2012 PEA .

This st ripping ratio does not include pre -production stripping of approximately 1.3 million m3 of

overburden material. When all waste rock and overburden material is include d, the LOM stripping ratio

is 7.9:1. All mined ounces in the open pit are within the Meas ured and Indicated categories. Seventy per

cent of the mineable ounces within the Underground are classified within the Measured and Indicated

categories which represent a significant increase from the 2012 PEA. UG production is envisioned to be

carried out at an average rate of 1,600 tonnes per day using the long hole stoping method on 30 metre

sublevels. Average UG operating costs have been estimated at $77/tonne, a 28% increase over the cost

assumption in the 2012 PEA.

In the March 8, 2017 press relea se announcing the PEA, the Company disclosed total cash cost

estimated at US$518 per equivalent gold ounce (“AuEq”) and an all -in sustaining cost (“AISC”), as

defined by the World Gold Council, estimated at US$566 per AuEq. The final total Cash Cost and all-in

sustaining cost were calculated at US$525 AuEq and AISC at US$611 , respectively . There were no

changes to the financial model used in the PEA or any other changes from the March 8, 2017 press

release.

The PEA was prepared in accordance with National Instrument 43 -101 and the technical report that

summarizes the results of the 2017 PEA is available on the Company’s website

www.treasurymetals.com and on Sedar (www.sedar.com).
