Defiance Commences Drilling at San Acacio

Exploration Programs

DEFIANCE COMMENCES DRILLING AT SAN ACACIO

FOR RELEASE: May 16, 2017 TSXV: DEF

OTC: DNCVF

Defiance is pleased to announce that it has commenced a drill program at the San Acacio Silver

Project in the Zacatecas silver district. This drill program will target the expansion of the current

deposit and will focus specifically on following up on the Esperanza and Almaden Targets.

Previous drilling at Esperanza intersected 12.7m grading 297g/t Silver Equivalent (“AgEq”). At

Almaden, drilling returned 8.3m grading 278 g/t AgEq. Both of these targets are open to depth

and along strike.

A third target that will be tested is the Quartz -Pyrite Breccia that was discovered in the

Guadalupe area of the project. The Breccia exhibits signs that it may represent a completely new

system richer in gold and zinc mineralization.

“We are excited to commence drilling at the San Acacio deposit and to follow up on the many

targets that exhibit the potential to dramatically increase the size of the current resource. The

current focus continues to be on the portion of the San Acacio project that has returned strong

results, namely beneath the 1.2 km of historic workings on the vein along with the newly defined

Quartz-Pyrite Breccia target.” said Bruce Winfield, President and CEO of Defiance Silver Corp.

Defiance drilling to date has extended mineralization below the base of the current resource in

two of the past producing zones , Al maden and Guadalupe. Results were excellent , producing

long intersections of high grade mineralization in the extension to depth of two of the zones as

follows.

** Grade not calculated because of no data for open mine workings

***True Widths are approximately 70% to 80% of each intersection

**** Calculated using zero grade for the mine openings.

Results from drill hole SAD15 -10 includes two historic mine openings that were assigned no

grade. Even with this artificially low assumption, the intercept returned the strong grade of

163.07g/t Ag Eq. It can be assumed that the high -grade was mined out by the historical mi ners.

If this were to have been left in -situ, the grade would have been considerably higher. This

extends the depth of the strongly mineralized main vein 150m below the base of the current

resource.
