Pan American Silver Reduces Certain Activities at the Dolores Mine

Vancouver, B.C. - May 28, 2018 - Pan American Silver Corp. (NASDAQ: PAAS; TSX: PAAS) (“Pan American Silver”, or

the “Company”) today announces that it has initiated steps to reduce certain activities at its Dolores mine in

Mexico following recent security incidents along the access roads being used to transport personnel and materials

to and from the Dolores mine. The Company is working with state and federal authorities to provide safe access to

the mine. The mine site remains secure. Ore stacking to the leach pads and the processing plant are currently

operating at normal rates.

"Our priority is the safety and security of our personnel. We have been monitoring the situation, and with the

recent incidents that have occurred along the access roads, we have determined the prudent course of action is to

suspend personnel movements to and from the mine until the roads are safe for our employees," said Michael

Steinmann, President and Chief Executive Officer of the Company.

The Company will maintain personnel at the mine at levels necessary for site security and reduced operating

activities.
