Seabridge to Begin Drill Campaign at Quartz Rise on Iskut

Project

TORONTO, July 10, 2017 (GLOBE NEWSWIRE) -- Seabridge Gold (TSX:SEA) (NYSE:SA) announced

today it has nearly completed the surface sampling and geophysics required to establish drill locations at

its 100% owned Iskut Project in northwestern British Columbia and drilling will begin shortly. The focus is on

the Quartz Rise target which emerged from last year ’s program. Two phases of core drill testing are

planned totaling 8,500 meters to evaluate the potential for high -grade gold concentrations within the

untested Quartz Rise lithocap.

Over the past several months, considerable historical data has been compiled and integrated into the

results obtained from Seabridge ’s 2016 program which included 13 new core drill holes, re -logging of

historical drill holes, a full tensor magnetotellurics (MT) survey and a hyperspectral survey. Interpretations

of this robust data set continue to support the presence of a large, preserved Jurassic calc -alkalic porphyry

system at depth, with an overlaying epithermal mineral system obscured by extensive leaching of the

Quartz Rise lithocap.

Detailed work is now in progress to define specific drill locations. Surface mapping is identifying multiple

mineralized structures projecting into the Quartz Rise target area. These structures appear to form a

graben which constrains the most intense alteration.  Further surface hyperspectral data collection has

confirmed the chemical expression of higher temperature occurrences associated with this graben feature

and co -incident with a promising negative magnetic anomaly. The primary target area hosts a package of

clay-and-silica-altered tuffaceous rocks that are intensely leached at surface. Conceptually, the target

appears to be a stacked lithocap -hosted precious metals system similar to the El Indio (Chile), Mulatos

(Mexico) and Baguio (Philippines) gold deposits.

Commenting on the program, Chairman and CEO Rudi Fronk noted that “we are pursuing a classical model

of metal deposition at Iskut which seems to explain the known data. In our view, Iskut hosts district -scale

porphyry-style mineral systems similar to our nearby KSM project. These systems account for Iskut ’s

numerous gold and copper mineral occurrences. Our data suggests these systems could be largely intact

from top to bottom, unlike KSM. We are concentrating our work on the upper parts of these systems,

targeting the high -grade gold potential which historically has been the hallmark of the Iskut district ”.

The Iskut Project was obtained when Seabridge acquired SnipGold Corp. in June, 2016. The property is

located in northwestern British Columbia, about 110 km northwest of Stewart, BC and 30 km by air from

Seabridge’s KSM Project. The Iskut property consists of a contiguous block of 100 BC Mineral Claims, 2

Mineral Leases and 13 Crown Grants covering 29,436 hectares (294 km 2) situated in the Liard Mining

Division.

The consolidated land package has undergone intermittent exploration since 1907 with the majority of the

work carried out in the late 1980s and early 1990s. More than 30 independent operators have owned and

worked claims within the Iskut property and their uncoordinated efforts discovered numerous promising

targets. Very few of these discoveries have been systematically explored over the past 20 years. The

property includes the former high grade gold Johnny Mountain Mine and the copper -gold Bronson Slope

resource.  

Exploration activities by Seabridge at the Iskut Project are being conducted under the supervision of

William E. Threlkeld, Registered Professional Geologist, Senior Vice President of the Company and a

Qualified Person as defined by National Instrument 43 -101. Mr. Threlkeld has reviewed and approved this

news release. An ongoing and rigorous quality control/quality assurance protocol is employed in all

Seabridge drilling campaigns. This program includes blank and reference standards. Cross -check analyses

are conducted at a second external laboratory on at least 10% of the drill samples.

Seabridge holds a 100% interest in several North American gold projects. The Company's principal assets

are the KSM and Iskut Projects located near Stewart, British Columbia, Canada and the Courageous Lake

gold project located in Canada's Northwest Territories. For a full breakdown of Seabridge's mineral

reserves and mineral resources by category please visit the Company's website at

All reserve and resource estimates reported by the Corporation were calculated in accordance

with the Canadian National Instrument 43 -101 and the Canadian Institute of Mining and

Metallurgy Classification system. These standards differ significantly from the requirements of

the U.S. Securities and Exchange Commission. Mineral resources which are not mineral

reserves do not have demonstrated economic viability.

This document contains "forward -looking information" within the meaning of Canadian

securities legislation and "forward -looking statements" within the meaning of the United States

Private Securities Litigation Reform Act of 1995. This information and these statements, referred

to herein as "forward -looking statements" are made as of the date of this document. Forward -

looking statements relate to future events or future performance and reflect current estimates,

predictions, expectations or beliefs regarding future events and include, but are not limited to,

statements with respect to: (i) the extent and timing of this year ’s drill program; (ii) the

interpretation of the exploration results at the Iskut property supporting the presence of a

large, preserved Jurassic calc -alkalic porphyry system at depth, with an overlaying epithermal

mineral system that is obscured by extensive leaching of the Quartz Rise lithocap and that this

is similar to the El Indio (Chile), Mulatos (Mexico) and Baguio (Philippines) gold deposits, the

projection of multiple mineralized structures into the Quartz Rise target area and the

appearance that these form a graben that constrains the most intense alteration; (iii) the Iskut

property hosting a district -scale porphyry -style mineral systems and that such systems remain

intact from top to bottom with characteristic epithermal tops that have high grade gold potential;

and (iv) the Iskut property mineral resource at Bronson slope. Any statements that express or

involve discussions with respect to predictions, expectations, beliefs, plans, projections,

objectives or future events or performance (often, but not always, using words or phrases such

as "expects", "anticipates", "plans", "projects", "estimates", "envisages", "assumes",

"intends", "strategy", "goals", "objectives" or variations thereof or stating that certain actions,

events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved, or

the negative of any of these terms and similar expressions) are not statements of historical fact

and may be forward -looking statements.

All forward -looking statements are based on Seabridge's or its consultants' current beliefs as

well as various assumptions made by them and information currently available to them. The

principle assumptions regarding disclosure on the Iskut Property include: (i) that the Company

will be successful in future efforts to finance the Company; and (ii) the mineralized system at the

Iskut Property will conform to similar systems elsewhere. The principle assumptions regarding

disclosure on the reserve at the KSM Project are set forth in Seabridge's Annual Information

Form filed with SEDAR in Canada (available at www.sedar.com ) for the year ended December 31,

2015 and in the Corporation's Annual Report Form 40 -F filed with the U.S. Securities and

Exchange Commission on EDGAR (available at www.sec.gov/edgar.shtml ) Although management

considers these assumptions to be reasonable based on information currently available to it,

they may prove to be incorrect. Many forward -looking statements are made assuming the

correctness of other forward looking statements, such as statements of net present value and

internal rates of return, which are based on most of the other forward -looking statements and

assumptions herein. The cost information is also prepared using current values, but the time for

incurring the costs will be in the future and it is assumed costs will remain stable over the

relevant period.

By their very nature, forward -looking statements involve inherent risks and uncertainties, both

general and specific, and risks exist that estimates, forecasts, projections and other forward -

looking statements will not be achieved or that assumptions do not reflect future experience.

We caution readers not to place undue reliance on these forward -looking statements as a

number of important factors could cause the actual outcomes to differ materially from the

beliefs, plans, objectives, expectations, anticipations, estimates, assumptions and intentions

expressed in such forward -looking statements. These risk factors may be generally stated as

the risk that the assumptions and estimates expressed above do not occur, but specifically

include, without limitation: risks relating to variations in the mineral content within the material

identified as mineral reserves or mineral resources from that predicted; variations in rates of

recovery and extraction; developments in world metals markets; risks relating to fluctuations in

the Canadian dollar relative to the US dollar; increases in the estimated capital and operating

costs or unanticipated costs; difficulties attracting the necessary work force; increases in

financing costs or adverse changes to the terms of available financing, if any; tax rates or

royalties being greater than assumed; changes in exploration, development or mining plans due

to changes in logistical, technical or other factors; changes in project parameters as plans

continue to be refined; risks relating to receipt of regulatory approvals or settlement of an

agreement with impacted First Nations groups; the effects of competition in the markets in

which Seabridge operates; operational and infrastructure risks and the additional risks

described in Seabridge's Annual Information Form filed with SEDAR in Canada (available at

www.sedar.com ) for the year ended December 31, 2015 and in the Corporation's Annual Report

Form 40 -F filed with the U.S. Securities and Exchange Commission on EDGAR (available at

www.sec.gov/edgar.shtml ). Seabridge cautions that the foregoing list of factors that may affect

future results is not exhaustive.

When relying on our forward -looking statements to make decisions with respect to Seabridge,

investors and others should carefully consider the foregoing factors and other uncertainties

and potential events. Seabridge does not undertake to update any forward -looking statement,

whether written or oral, that may be made from time to time by Seabridge or on our behalf,

except as required by law.
