Gran Colombia Gold Corp. (TSX: GCM) (OTCQX: TPRFF) announced that it has changed its name to GCM Mining Corp. effective immediately and its website can be found at www.gcm-mining.com.

Commenting on the name change, Serafino Iacono, Executive Chairman of the Company, said “We are very proud of our Colombian roots and, in Colombia, we will continue to operate as Gran Colombia. Our new corporate name reflects our strategy to grow through diversification, expanding our operations and investments to other countries and broadening our products to include other metals beyond just gold and silver. With the acquisition earlier this year of the Toroparu Project in Guyana and our equity stake in Denarius and its flagship Lomero Project in Spain, we have commenced our diversification strategy. We have a strong balance sheet and we are fully funded to build Toroparu, one of the largest undeveloped gold/copper projects in the Americas. We expect to announce the results on the updated mineral resource estimate and preliminary economic assessment for Toroparu shortly, solidifying its position along with our Segovia Operations, as a cornerstone asset in GCM Mining Corp.”

There is no change to the Company’s trading symbols for its common shares and common share purchase warrants and we expect that trading on the Toronto Stock Exchange under the Company’s new name will formally commence on December 1, 2021. In the interim, trading will continue under the Company’s old name. The new ISIN and CUSIP numbers for the Company’s common shares are CA36168L1058 and 36168L105, respectively. For the Company’s listed common share purchase warrants (TSX: GCM.WT.B; OTC Pink: TPRXF), the new ISIN and CUSIP numbers are CA36168L1132 and 36168L113, respectively.
