FOR IMMEDIATE RELEASE - August 19th, 2015

Cerro Grande Mining Corporation Reports Disruption of Operations at its Pimenton Mine

Toronto, Ontario, Canada - Cerro Grande Mining Corporation (the "Company" or "CEG") (CSE:CEG)(OTCQB:CEGMF) reported that operations at its Pimenton mine have been interrupted.
A partial road closure (from the railroad crossing outside of Los Andes to Codelco's Andina mine) caused by Codelco's striking subcontract workers at Andina who also temporarily hijacked a Pimenton truck waiting at the rail crossing to go to the mine stealing a load of timber for feeding their fires on the road, during the period of August 3 to the 7. These actions by the striking Andina workers interrupted both the shipments of copper concentrate and gold dore as well as the shipment of fuel oil into the Pimenton mine. This was followed by a snow storm which began on Saturday, August 8 to August 13th during which time approximately 2.60 meters of heavy wet snow fell at Pimenton, which caused the mine operations to be shut down for 3 days and the plant operations to be shut down, because of lack of fuel, until August 18th when the road was partially reopened.
The primary reason for the road closure is that Pimenton had a D5 level (15 meters in height and
235 meters along the road center line) avalanche mid way along the 80 kilometer road leading into Pimenton. A D5 avalanche on the US Destructive Scale, as described in the Standards for

NR2015

Weather and Avalanche Recording Guidelines for the U.S. as the most destructive of avalanches recorded in the U.S.
This series of events has adversely impacted operations at Cerro Grande Mining Corporation's
100% owned Pimenton mine and will have a negative impact on the Company's earnings in its fourth fiscal quarter ended September 30th, 2015.
Cerro Grande Mining Corporation is a minerals producing, exploration and development company with properties and activities currently focused in Chile.
