Gran Colombia Gold Completes Acquisition of Approximately 15% Interest in Sandspring Resources Ltd.

TORONTO, July 26, 2018 (GLOBE NEWSWIRE) -- Gran Colombia Gold Corp. (TSX:GCM) announced today that it has completed its previously announced acquisition of an investment in Sandspring Resources Ltd. (TSX-V:SSP) (OTCQX:SSPXF) (“Sandspring”) (the “Transaction”). Sandspring is a Canadian junior mining company currently moving toward a feasibility study for the multi-million-ounce Toroparu Project in the emerging western Guyana gold district. In connection with the Transaction, Lombardo Paredes Arenas, Chief Executive Officer of Gran Colombia, has been appointed to the board of Sandspring, effective immediately.

Through completion of the Transaction, Gran Colombia has received 15,000,000 common shares of Sandspring in consideration for its 30% carried participating interest in the Chicharron Project located within its Segovia mining title.  Gran Colombia has acquired a further 16,000,000 Units of Sandspring at CA$0.25 per Unit in connection with Sandspring’s CA$10.25 million private placement of 41,000,000 Units completed today.  Following completion of the Transaction and the private placement, Gran Colombia now has control and direction over an aggregate of 31,000,000 common shares and 16,000,000 share purchase warrants of Sandspring.  Each share purchase warrant entitles Gran Colombia to purchase one additional share of Sandspring at CA$0.40 for a period of sixty (60) months. The securities acquired in connection with the private placement are subject to a four-month-and-one-day statutory hold period.  The common shares controlled by Gran Colombia represent approximately 14.78% of the outstanding common shares of Sandspring. Assuming exercise of just the warrants controlled by Gran Colombia, when combined with its existing ownership, Gran Colombia would have control and direction over 47,000,000 common shares representing approximately 20.83% of the then outstanding common shares of Sandspring.

Serafino Iacono, Executive Co-Chairman of Gran Colombia, commented, “We are pleased to have closed this investment in Sandspring. From our previous experience in the Guiana Shield and the work we have completed in our due diligence process, we see opportunity in their Toroparu Project and we look forward to assisting management in taking this project to the next level.”

Gran Colombia has acquired the securities of Sandspring for investment purposes and has no present intention to acquire further securities of Sandspring, although Gran Colombia may in the future acquire or dispose of securities of Sandspring, through the market, privately or otherwise, as circumstances or market conditions warrant.

Copies of the early warning report filed by Gran Colombia in connection with completion of the Transaction and the private placement are available under Sandspring’s profile on SEDAR () or by contacting Gran Colombia directly.
