Seabridge Gold Begins Drilling Quartz Rise Target on Iskut Project

IP Anomalies and Mapping Point to Possible Source of High-Grade Gold Assays

TORONTO, Aug. 21, 2018 -- Seabridge Gold (TSX:SEA) (NYSE:SA) announced today it has commenced drilling the Quartz

Rise high-grade gold target on its 100%-owned Iskut Project in northwestern British Columbia. 

Last year’s drill program, the first ever at Quartz Rise, confirmed the presence of a gold-bearing intermediate sulfidation

epithermal system beneath the Quartz Rise lithocap. This was our target concept. The drilling intercepted several narrow,

discontinuous intervals of high-grade gold. A subsequent 3D induced polarization (IP) geophysical survey together with detailed

geological mapping and sampling of available rock faces indicate that the 2017 drilling may not have been in the correct

orientation. New results from cliff face sampling show exceptional gold results (Attached Figure) that appear to correspond

with a favorable IP chargeability anomaly under Quartz Rise.

Rudi Fronk, Seabridge Chairman and CEO, commented: “The Quartz Rise target began as a theoretical concept based on our

understanding of porphyry gold-copper systems at our KSM project. In 15 months of work, we have learned a great deal and

the concept has become a real, data-driven target. We believe we can now find the source of the high-grade gold associated

with sulfide-bearing quartz veins at Quartz Rise. Our research continues to uncover compelling reasons why the lithocap may

be hiding a significant, near surface epithermal precious metals system.”

Quartz Rise is underlain by Jurassic felsic volcanic stratigraphy consisting of coarse lithic tuff intercalated with densely-welded

tuffaceous flows, incestuous porphyritic sills and tuffaceous sedimentary rocks, deposited unconformably on Triassic marine

sedimentary rocks. This is the geological time break that has proved to be productive elsewhere in the region. At Quartz Rise,

the coarse lithic tuff tends to show much more intense leaching and acid alteration than do the overlaying densely-welded tuff

units which appear to have capped the fluid flows.  Exposures of the coarse lithic tuff host in the cliff face have yielded

exceptional gold values in more intensely-altered intervals found in proximity to IP chargeability anomalies. 

This year’s drilling is designed initially to follow gold-bearing veins in the coarse lithic tuff away from the cliff face into the

chargeability anomaly.  Additional holes will test other chargeability targets. The 3,000 meter core program can be expanded

contingent on success.   

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

the Company with securities regulators. A detailed cautionary statement outlining the forward looking statements
